5870 Crossfire Performing Worse Than A Single 5870


I just bought 2 5870's today after much research and reading benchmarks they are the way to go, and i have installed them, and in crossfire they are performing, well under what a single 5870 should be doing. My 3d mark vantage score with crossfire is 14, 186. Yes, in crossfire, i heard it should be up near the 22, 000 mark. Also, in mw2 with settings maxed out and crossfire enabled, i am getting an average of 48fps, according to guru 3d it should be 128fps at my resolution with a single card, my old 8800gt's in sli were getting me 90+ and the 5870's should eat the 8800gt's allive and then some. I have the worlds worst luck, so if you guys could point me in the right direction that would be awesome, cause i really want to put my hard earned dollars to work as im sure you can understand.

5870 Crossfire 4th Monitor

I can't get the second card to detect any displays. Has anybody else had this problem? I have crossfire enabled and i can see the performance increase in bc2 but only with 3 displays. I can even hookup the 4th monitor in place of one of the eyefinity monitors and it detects it. I have tried dvi and hdmi in the second card and neither works. Do i need to try the 10. 3 beta? I am currently 10. 2.

4 Monitors On A Single 5870

I'm looking to eyefinity 4 monitors (3 would be 1 group and extended on the fourth). My monitors don't have display ports, and so from what i read i would have to buy active adapters for the last two monitors. If i just buy another 5870 would i be able to use the dvi on the second card?

It seems it would be better to go ahead and get another card instead of spending 200$ on adapters. Is there something i'm missing or is this the only way?

A Single 5870 Enough For A 30 Inch Monitor ?

About to order my new rig to coincide with the release of windows 7, i got most of what i want in there already figured out:

Phenom ii x4 965 (the 955 is only 20 bucks cheaper)
Msi 790fx-gd70
4 gb ocz black edition 8-8-8-24 1600
2 640gb wd caviar black in raid 0
Sapphire radeon hd 5870
Lian li x1000
Corsair tx850w
Samsun 305t 30 inch monitor @ 2560x1600
Prolimatech megahalems

I plan on playing games at max settings crysis/crysis warhead included. I am worried that at that resolution 1 5870 will not cut it and i am already over my budget by a solid 300$ to afford the second graphic card would have to wait for the end of next november probably. If i wait till november i might as well see what the new nvidia cards look like and just buy this thing post xmas (might get a better deal!). So the way i see it i can do one of two things, buy it now or buy an xbox 360 to tide me over till january and buy the best computer i can afford then! I refuse to pay 3300$ for a computer and not bbe blown away by the performance!

5870 Crossfire Upgrade - Frame Rate Loss In Oblivion

I know i'm contradicting myself in saying i wouldn't purchase a second 5870 but my impulsive ass just had to rent an additional xfx 5870. I swear i went to frys for a different reason but it was staring me in the face! I thought to myself, i should know what future upgrades are in store for me if i stick with this 5870 and one day i decide to crossfire it right?

Well i spent several hours last night playing around with my dual 5870 setup and, i wasn't impressed at all with crossfire performance. 3dmark06 went up by 2k (wooo) from 26xxx to 28xxx. Crysis seemed a little faster but had severe slowdown at certain areas of the map (it was like as if i was maxing out the frame-buffer or something). But i mean even when it was faster, weren't not talking much, maybe like 20% at most. That's really *** poor scaling i'd say. I do like how it opened up new function in ccc called gpu scaling which corrects my hdtv 24hz issue without custom res but ccc is still one cluster of a gui and still buggy as ***. Sometimes crashes (have to re-run the runtime). Sometimes when i close crysis, it leaves my desktop messy looking, as if it's trying to apply all my aa & af in game settings to my desktop now and i have to reboot to correct this. And also ati for whatever reason has never rendered my desktop as crisply as nvidia. I have no idea, it's like the text isn't as clear but i was willing to put up with that if these cards were a significant upgrade from my old setup. Games take precedence after all. But worst of all, the biggest disappointment was. My favorite game, oblivion took a frame-rate hit! Meaning i got a better frame-rate with a single 5870. This is with 9. 12 /w hot-fix. I dunno $920 (plus tax) of an "upgrade in video-card power" and really it isn't proving to be much faster than my old dual 260 (216 cores). I know oblivion is a ridiculously old game but it really is the most important game for me and is what makes or breaks my decision making on an upgrade. Are there any other oblivion players in here who saw a frame-rate hit with dual 5870s? Btw, for those of you who have sigs turned off, i game at 1920x1080 on win7 64 with an i7 @ 4. 2ghz /w ht.

What Driver For The 5870 ?

What driver is everyone using for their new 5870? The one on the cd or the 9. 9 drivers from ati's website? Are their any 9. 10 beta's floating around.

Using 3 Monitors With 5870

Who is planning on using 3 monitors with their 5870? If so what size and resolution monitors are you going to use? Is anyone planning on using 3 projectors? I see you can buy the older 1024x768 projectors for around $600.

5850 Vs 5870

Just wondering what would be the way to go. 2 x 5850's in crossfire or one 5870? I do a fair bit of gaming and multimedia production. Any pros and cons of each setup? Im looking at a new machine and the mobo im looking at supports crossfire.

Xfx 5870 Drivers

I am not pleased. I have been running xp for years, i just bought a 5870 and installed windows 7 rc 64 bit. I used the drivers from ati site for the 5870. Diablo ii locks up at times. Call of duty 4 will not play in multiplayer mode, only single player. I tried drivers from the cd, same thing. I would go back to xp, but i see there is no xp driver for the 5870. This is lame, and i am not sure who is at fault, windows 7, or ati. I like upgrading so that the 2 games i play, don't work on my new fancy hardware and os.

New Beta Drivers For 5870

It's a new rc build of the 9. 10s. The only download link i have found so far is the megaupload. I've scanned it with avira, and it didn't find anything amiss. Now i'm off for some testing. Download link

Edit. Seems like it's not a new driver. It's the same actual drive as the msi branded rc7, but with the msi branding gone. With all these betas, amd's driver releases are encroaching on nvidia territory

5870 Not Going Full Screen

So i';ve finally got my i7 rig together with a gigabyte ex58-ud5 mobo, i7 920 currently @4. 0g (testing in process right now) and an ati (re-flashed to asus) 5870 video card. During one of my video card tests it failed and i think that is when the monitor decided to not go full screen. I have about a 1" blank area the entire way around the display that is not being used sort of like when you are watching a broadcast channel in hd that does go full screen. I've tried adjusting the monitor settings, resetting the monitor settings, and adjusting the screen resolution etc. I also noticed that when the screen goes blank from inactivity that it does not wake back up. Not sure if this is related or not though. Any ideas?

Monitor or video card or a combo of the two?

Can I Run 4 Monitors On 5870 ?

Obviously not in eyefinity mode, but is it possible to run 4 monitors when you are in a desktop environment? I have an hdtv on the wall above my setup and would like to use it for movies. So does it work and just disable during eyefinity?

How Can 5870 Handle 3 Monitors ?

Ok the early reviews of the 5870 are out, to be honest not as fast in the benches as i expected. On average it is just better than the 4870x2, which is still awesome. But then how can this thing do multiple screen gaming so smoothly ?

My main point i am trying to make here is, how can this one new card handle extreme crazy resolutions like 7680x1600, that is 3 - 30" displays. I mean for years we have been foaming at the mouth for a single card can even game at 2560x1600res and still be playable, but now this new card can do that on 3 monitors easier ? Doesn't that mean the card needs to be 300% faster than the best already out there?

A single 4870x2 could never in it's wildest dreams game on 3 high res screens smoothly, i mean 24" + size monitors. Now this new single 5870 comes out, which is faster, but not night and day above the 4870x2, and it can suddenly handle multiple screens all at once with ease, but only being a little faster?

Catalyst Drivers On 5870

Finally got my new machine built (in sig) and windows 7 installed without issue. However as soon as i installed the catalyst drivers (latest from ati site 8. 66 rc6) windows boots and the monitor goes straight into power save mode as if the frequency is too high or something. I can boot into safe mode with no problems. Am going to try removing the drivers in safe mode and reinstall them, see if that helps. I already tried installing the rc7 version but catalyst installer needs to be able to detect the hardware, unlike the nvidia drivers, so they wont install in safe mode. I expect i will reinstall windows tonight and try again if uninstalling doesn't work. Any other ideas? Anyone else had issues like this?

5870 - Displayport Issue

I seem to be experiencing an issue with my 5870, which only happens when connected via display-port. There are two instances, which result in the monitor going into power-save and display no source for a few seconds before restoring. The other two monitors i have connected via dvi at the same time do not run into this issue. All settings on the control panel are currently default. 1) anytime uac prompts for admin approval (displayport loses signal for a second)
2) random intervals during game-play

I am currently running the following system:

Windows7 x64 rtm (clean msdn install, not upgrade)
Q6600 @ 2. 4
8gb ddr2 (4x2)
150gb raptor (no other hdd)
Sata dvd-rw
Xfx 5870 (not overclocked)
Corsair hx520

Displays connected:

Dell 2007wfp (dvi) 1680x1050
Dell 3008wfp (displayport) 2560x1600
Dell 2408wfp (dvi) 1920x1200

Initially i suspected the powersupply to be the issue, but it should be fine for what i'm currently running. I then noticed that uac prompts also caused the loss of signal while under zero load. I've tried the following to resolve the issue already:

1) drivercleaner + update to 10/13 drivers
2) used displayport on the 2408 instead of the 3008, issue then occurs on the 2408

I'm beginning to wonder if this could be an issue with my displayport cable or the card itself as i haven't seen similar reports yet. Any suggestions on what else i might be missing? Should i go ahead and try a different power supply?

5870 Screen Tearing

I recently purchased a sapphire branded ati 5870, as i was replacing a geforce card (and because it was about time anyway) i decided to format before installing the card. I installed win 7 ultimate x64, installed the drivers and began experiencing odd screen tearing. Figuring this was a win 7 issue, i formatted again. This time installing vista ultimate x64, installed latest drivers and the screen tearing happened again!

This persisted during gaming, on the desktop and regular apps (word, ie, etc). After disabling the a. I. Feature the tearing stopped occuring during gaming. But tearing on desktop, ie, etc still remains, i don't want to blame this on drivers as if i do waiting till they fix them will most likely take me past being able to rma the card. Any suggestions?

(I know the psu is not great, had one go bad needed a fast replacement. Although if you read this review http://www.Hardwaresecrets.com/article/556 it is more then capable of pausing 700+w so i figure that may not be causing this). Any help is greatly appreciated.

3 Monitors With Different Resolutions With 5870

Quick question. I have 3 - 24" monitors. 2 of them are 1920x1080 and the third is 1920x1200. I do not want to game on all 3 screens (eyefinity), just one. So, will the 5870 support all 3 monitors at their native resolutions for surfing the web, etc?

I also understand that i need a display port adapter. Does it have to be an "active" adapter even though it won't be used for gaming? Anyone have a link to what i need?

Radeon 5870 Not Fast

Really disappointed with my radeon 5870's performance in crysis. In very high settings, i got 27 fps with my old card (gtx 260) with the 5870 i get 30 fps, almost no improvement (was expecting at least 40). There must be a bottleneck somewhere. I have a e6850 core 2 duo (3ghz) and 3 gb ddr2-800 ram. I know that a quad core is really important for gta 4, but according to this test:

http://www.Guru3d.com/article/cpu-scaling-in-games-with-quad-core-processors/9

It doesn't seem to matter that much in crysis. I use win xp with the "very high settings" hack

Flashed 5850 To A 5870 Bios

This is really odd. Is it possible that i flashed my 5850 to a 5870 bios? I'm thinking maybe i accidentally flashed to some custom bios, or possibly a 5870 bios? For some reason ever since the flash my default clocks are 850/1200. The same clocks you would find on a asus 5870. I've been running the card this way all this time though posting benches etc. On these forums, so i doubt it's a 5870 bios. I'm thinking maybe i picked the wrong link accidentally in a thread which was for the asus 5870 - but perhaps more likely it's just a custom bios. ? Is this even possible to flash a 5850 to a 5870 bios?

Asus 5870 Displayport Native

I have a asus 5870 connected to two iiyama 18inch (1280*1024) and one hp 24inch lp2475w connected via display port (using display port cable native attach). The hp randomly flashes on and off

I am using windows 7 64bit. Any suggestions? I have been through the forums search and have read people flashing their cards. How can i find out which firmware i have currently, would it be worth flashing?

I have a 850w power supply. Would it better to use a second card (which i already have) for the two iiyama and use the dvi for the 24inch hp on the 5870?

Xfx 5870 Second Monitor Issues

I have been having an issue on 2 different systems that have xfx 5870's in them. Under windows 7 x64, almost every time you boot the system, the extended desktop on the second monitor will not properly enable on a reboot. The system shows the monitor is enabled as an extended desktop, but you have to disable and reenable it for it to actually display an image. Has anyone else experienced this?

Ati 5870 Driver Issues

This problem has been recreated on 10. 1, 10. 2 (& using a hotfix), 10. 3 release candidate drivers
As well as 2 separate sapphire hd 5870 graphic cards. Needless to say i'm struggling with my patience and need some help. Some of you may remember my graphical issue with my mouse cursor doing some crazy things. Its very consistent, happening more often than not anymore. Other items of interest. This happens when in eyefinity across 3 monitors (2xdell 2408 &1 dell 2405)

Also it happens when not in eyefinity but each monitor being separate

It also happened when i was only using 2 monitors (samsung t260hd & dell 2405)

The cursor issues will only happen on one monitor and not the other 2. It is random which monitor it will happen on, mostly its the left, but sometimes the center. Never more than one monitor at a time. I've noticed at times the cursor becomes distorted only after moving the cursor to the very bottom of the screen and bringing it back into view if you will, again random. Keep in mind since prtscrn does not take a pic of the mouse i have to use my dslr

Difference between the monitor on the left with the problem, but the middle monitor not so much. Bad

Good

This has just been a really rough experience and i appreciate any insight you guys may have. I am going to copy paste this into an ati support ticket once i figure out the right place to send this. Let me know if you guys want any further info like a dxdiag or something.

5870 + 4850 To Run 4 Monitors

Anyone know if you could utilize a 5870 with an older 4850 for the 4 dvi slots and run 4 monitors in eyefinity? Just a thought since i'd have to get rid of my 4850 if i couldn't find a use for it. Plus then you can snag a 3rd and 4th dvi based monitor instead of looking for a dp. Just a thought.

5870 Overclocking And Two Monitors, Flickering

I have my 5870 overclocked to 925/1275. Good overclock, safe, worked well. I hooked up a second monitor, but i'm not using it for eyefinity, its just the traditional additional space monitor. Whenever the card is overclocked (even mild overclocks) the second screen flickers whenever moving between different windows, or just about any time the mouse moves over anything new. This is exclusive to the second monitor, and exclusive to when it's overclocked. I have no problem waiting for drivers to mature to overclock since i suspect that's the issue, but i would like to know if any others have the same issue, make sure my card isn't a dud.

Asus 5870 Not Detecting Second Monitor

I've double checked all the usual stuff, drivers are good, card is good, outputs are good, cables are good. I just can't seem to get my 5870 to "see" my second monitor. I just threw it in my system, without a reformat, i used to be running a 8800gts 640. Anyone have any suggestions? I'm thinking its likely a reformat and reinstall of everything may fix the issue.

4879 To 5870 - Reinstall Drivers ?

Well, against my better (to save $$$ for christmas presents) judgment in a moment of weakness this weekend i pulled the trigger on an xfx 5870 from newegg's batch. It's replacing an msi 4890 i've had for a while. The order went thru, i've got a tracking # & should be getting the card on the day after tomorrow. I've routinely upgraded my video cards pretty regularly, selling off the old ones before their prices on ebay dropped too much, but every time over the last few years i've coupled the upgrade with a rebuild of windows (last time i went from an 8800gts to ati so reinstalling windows seemed like the smart thing to do). The thing is, i just rebuilt my system about a month ago because of a hard drive crash & installed windows 7, 64 bit at the time (from vista). It took a while to get my apps, email, shortcuts set up as i like them so i'm really not too thrilled about re-installing again this soon. Since i'm going from a 4890 to a 5870 my question is will there be any real benefit to reinstalling windows? Should i just wipe the ati drivers i've got on there now out & re-install just them or will everything be just as good / optimal if i just swap in the new 5870 card & let the currently installed drivers re-detect & adjust as however they do ?

I'm currently running the 9. 11 drivers & noticed on ati's site these are the same ones they've got listed on their download page for the 5870's so it's not like i'd be upgrading to a newer driver version.

5870 Dual Monitor Problem

So today i finally got my new 5870 xxx edition

http://www.Newegg.com/product/product.aspx?Item=n82e16814150456&cm_re=5870-_-14-150-456-_-product

I had completely removed my old nvidia drivers, and installed the latest ati drivers. Installed the 5870 and right at the start started having problems with duel display configuration. Can someone please answer me, for duel monitors is the hdmi and the 1st dvi port (on top) are the once im supposed to use for this setup? Because using 2 dvi ports doesn't seem to work. The 2nd dvi monitor is always black, even if you only use a single monitor using 2nd dvi it doesn't work. Whats strange when both monitors connected via dvi on the 1st monitor when accessing catalyst the 2nd display is there, but doesn't matter what i tried it doesn't want to turn on, you can see in the options, but the monitor it self doesn't want to turn on, even tho everything is on for this setup to work. For now i got this setup working using hdmi to hdmi and 1st dvi to dvi connection, but makes me wonder if the 2nd dvi is broken or something. Or is only meant to be using using 3rd monitor. Just in case my monitors are dell 2408wfp 24" and dell 2407wfp-hc 24" (both of them work using 1st dvi connection and dont work using 2nd).
