HD4870 1GB flickering issues....

what is your problem is that the manufacturer of the card you are using is not so good you should have tried saphire , pallet or sparkle and bfg all that you know .
you can try these hints just min your settings of diplay or re intall your opering system .
or you can uninstall your video card driver use the latest one on ati .
as far as iam concerned you should try nvidia's gtx 280 or 9800X2 or gtx 260 (216 cores).
ok try these things or contact the hardware engineer ok try out them and not overclock your cpu much .
ram should also be like for what is spec 1GB min .
don't use vista if you're using that cause vista is slower than xp or use xp genuine version . if you don't have financial problem use the gtx 260 gtx prices are same as the 4870 .

Well, powercolor is actually rated as good as sapphire over here and even has better cooling than sapphire. I actually found out what the issue is, its the ATI Catalyst version 8.12 seems to cause this problem if the memory speed is set above 900mhz and there hasn't been an update yet! So it seems like I have to down-tune my GPU!

Don't listen to Aftab Powercolor is a decent company and he seems to be a nvidia fanboi ATI and Nvidia are pretty much on par with each other when it come to their midrange cards with both their benefits and cons anyways your solution sounds more vesiable and let us know how it goes!  

Did some more research and I think i'll try installing 8.11 first, seems to solve the problem for some ppl. Hopefully this accounts for me too!

Ok, in the end I only installed rivatuner and turned overdrive off in CatalystCC 8.12. Adjusted the settings accordingly in rivatuner and the problem is solved! So for everyone having this problem, I can only advise to install rivatuner 2.2 and adjust the clock settings to the standard settings of the powercolor HD4870 card or higher if you want and it should still work fine.

Thanks mate - had exactly the same problem - thought id stuffed something up when installing it (it was pretty dusty inside my case when i whacked it in) - was giving me the ****.

Has been fixed by turning off ATI overdrive and using rivatuner to fix the settings as you suggested

Is interesting - if you're in hardware monitoring mode you can actually see the flickering conicide with a blip showing the change in frequency on the graph

Np, during gaming i actually realized that 800/925 was too much to handle and I couldn't get it stable. So i ended up going back to original OC 780/925 (even tho factory it is supposed to be 800 according to powercolor, but I received the card w/780mhz). Atleast the games don't random crash anymore. I did some research on it and seems that its is possible related to the powercolor BIOS.

Kinda dissappointed I must say, also my gpu temp stays around 55-60ish full load but - not sure anymore at the moment - I'm almost certain its the memory (memIO) that goes up to 100-110C during full load! Dunno but this kinda frightens me, normally I only payed attention to the cpu temps, but does anyone know if this is an average temp? or too high? Would it help if I add new heatsinks or replace the existing ones? and if so what kind of heatsinks would be advisable?

(This would be the first time for me editing my graphics card) I'm just not sure whether I should just leave the card as is with this temp or not. When I get home in the afternoon I'll post a follow up w/the temps I had recorded during gameplay (sacred 2 - fallen angel).

thanks in advance-

PS: I should add that I sometimes still get a VPU recovery error and when I then look at riva tuner monitoring mode, I get the impression that it was at the point where my memory hit 111C for a split second, it then dropped back to 100C. Temps within my case are 25C and 32C when gaming, room temp is 18C and I have a 40cm cooler side panel* and two 12cm fans blowing air out in the front and back. So my case is optimally cooled. It definately isn't a cooling issue, and as mentioned before the GPU core doesn't get too hot at all. I'm just thinkin that those heatsinks suck and can't keep **** cool. But I'm no expert....

*Its the aero-cool hi-tech 7 Pro (here is an image of the case found on google http://www.pcmasters.de/fileadmin/news/Aerocool/AeroCoo...)

Has anyone tried d/l the drivers from the powercolor site? can it be expected that those are different from the ATI drivers? Its catalyst 8.10 on the site so it seems a bit outdated to be honest...Anyone got any ideas?

Well its definately the Memory that is reaching such high temperatures mostly during gameplay around at 105, but sometimes it goes up to and remains at 110-112. If anyone has any ideas how I can increase the cooling on the memory I'm all ears!
