XFX GTX 275 - Crashing / Locking

Anyone have any recommendations for a 'suitable' PSU?

Shame really.. only just bought this Corsair but looks like it'll be going straight to eBay!

Leftover Ati drivers?

Would that be in the regedit?

I did un-install the ATI drivers but I suppose there could of been some files left somewhere. Will install it again and see what happens!

..just stuck the X800 back in as well.. haha.

Right, update.

Still crashing to blank screen after less than a minute 'in-game' in Battlefield 2142. Also tried Assassin's Creed - lasted around 5 minutes before crashing.

I'm getting an error reading "Display driver nvlddmkm stopped working and successfully recovered" each time I return to desktop. The drivers are the latest (190.38) and I've tried uninstalling and reinstalling about 5 times with no better results so far.

Any ideas? As I said above, I've checked Corsair's site and my PSU is one of the recommended products when I enter my rig into their power calculator, although when I go to XFX's website, they say the standard GTX275 (i.e. non brand) needs a minimum of 550w (which I have). However the XFX version of the card (again, which I have) requires a minimum of 620w.

Swings and roundabouts.. *sigh*

No not yet, are we talking a massive underclock or a very small one?

Could a fresh install of windows make any difference? I'm thinking about switching over to W7, though I'm not sure what the general compatiblity is like atm? Could it be shooting myself in the foot if I upgrade?

I'm just wary of spending £80 on a new PSU when i'm not sure if it's the cause of the problem or not..

By underclocking the card quite a bit, I would hope that the reduction in powerusage would show whether the PSU is really to blame for the crashes or if it is a software/OS issue.

Thats a quality psu i dont think the problems there but its possible. What are the temps of your card? I no nvidia card drivers stop responding if your card overheats.

Well my X800 has been in here for 3 years and never had a single issue. Upgraded to the GTX275 at the beginning of the week and it can't game for more than a minute on most things. BF2142 & Assassin's Creed = less than a minute actually in-game before it blank screens.

Temps are running at 45 idle then around 65 in game.. but that's not an accurate figure due to the fact it doesn't last for longer than a minute so I'd imagine it would get slighter hotter than that in a full game.

Call me stupid but I can't find the menu in Rivatuner to adjust the clock speeds?

Main tab>Customize button>Little GFX card icon>Nothing there? Just fan speeds.

Am I missing something, swear it used to be there?

Guys, success! (so far..)

Used EVGA's Precision Utility, decreased my core clock from 640 to 600 and it works fine. Been playing 2142 (looks awesome now!) for 2-3 hours and it's working fine.

So, what could of been the cause of the problem? When I've finished playing I'll crank the core clock back up by 10 and see what happens then. Power maybe?

I just installed my XFX GTX 275 and had the exact same problem when Playing Batman Arkham.. I discovered that the fan on the card would just stop in the middle of playing the game. Without lowering the performance, I changed my settings to manually control the speed of the fan when Playing games and this helped resolve the issue. Still working on why the fan stops when the auto fan feature is enabled, and I start playing games. Doesn't really make sense.

I have the same problem. XFX GTX 275 core ed. Game randomly freezes, locks up for few seconds in intervals, and I get artifacts on the screen, eventually a bsod or reboot; even the w7 hardward assesment tool ends up in a bsod. I have an expensive 620w Corsair PSU so doubt that's the problem. I had an ~old mobo with a Phenom X4 9850; got new mobo and Q8200 today, same problem. I had a 9800GX2 for some time and didn't experience this, so it's definitely not a problem with power (gx2 needs way more). Putting in my old 8800 GTS there's no problem.

I will return the card for repair or exchange; maybe it's a xfx batch with this same defect? Costed me $325 ;/ (europe)

I get the same problem with my 3870X2. There are some 40+ page long threads on various forums detailing it and, as it affects all makes of cards, its generally accepted to be a driver issue and, more specifically, how Vista handles them. From what I can tell a reinstall, or possibly just a good clean with driversweeper, should hopefully fix it. My card is still going back because one of the DVI ports is faulty too!

I have ruled out overheating and PSU problems (got a 680W Tier 2 SLI ready Hiper) and get either CTDs, lock ups or BSOD when I try to play a game. At first lowering the graphics settings allowed the games to work (similar in effect to underclocking the card I guess) however now even on lower settings they crash (I hope underclocking is a more permanent fix for your sake)!
