Right. Some benchmarks with my fist overclock. 1st one is at 1680x1050, 2nd one is 1920x 1080. All heaven settings are maxed out. GPU Core clock: 851MHz GPU Shader Clock: 1702MHz Memory Clock 2180MHz Voltage: 1075 Settings 1) Render: direct3d11 Mode: 1680x1050 8xAA fullscreen Shaders: high Textures: high Filter: trilinear Anisotropy: 16x Occlusion: enabled Refraction: enabled Volumetric: enabled Tessellation: extreme FPS: 32.4 Scores: 817 Min FPS: 15.5 Max FPS: 77.4 GPU topped out at 52c with fans at half speed. 2) at 1920x 1080 on my 40" TV FPS: 29.0 Scores: 731 Min FPS: 13.8 Max FPS: 68.2 Mode: 1920x1080 8xAA fullscreen Shaders: high Textures: high Filter: trilinear Anisotropy: 16x Occlusion: enabled Refraction: enabled Volumetric: enabled Tessellation: extreme This time temps topped out at 53c
Is the above any good? I think i could push the card further with more voltage but i dont really need too. Not sure about mem clock speed either, should i bump this higher? Witcher2 and NFS Shift both play ok - With GPu temps hitting 58c after an hour of Witcher2 at 1920x1080.
Seems about right i think, i assume ur running Heaven 2.5 ? i'll do a run a bit later with a single 580 on similar clocks and let u know the result.
Your overclock is good enough when you can run your game on the settings you want above your target FPS. No point it trying to push it further unless you really need more FPS. (but that just means your target was wrong )
that's pretty good.. did a heaven bench back when I got my 6970- pretty close to that at 1080p maxed out.. haven't tried the newer drivers.. think that was on the 10.6 cat back when ran heaven on my 460 remember getting a bunch of visual errors (flashing colored balls) around the cannons on the castle top scene but good numbers.. ati no visual errors at all =] love this card really Code: FPS: 28.1 Scores: 707 Min FPS: 12.0 Max FPS: 71.7 Hardware Binary: Windows 32bit Visual C++ 1500 Release May 21 2010 Operating system: Windows 7 (build 7600) 64bit CPU model: Intel(R) Pentium(R) CPU G6950 @ 2.80GHz CPU flags: 4200MHz MMX SSE SSE2 SSE3 SSSE3 HTT GPU model: AMD Radeon HD 6900 Series 8.861.0.0 2048Mb Settings Render: direct3d11 Mode: 1920x1080 8xAA fullscreen Shaders: high Textures: high Filter: trilinear Anisotropy: 16x Occlusion: enabled Refraction: enabled Volumetric: enabled Replication: disabled Tessellation: extreme
yes please that would be very interesting. I dont have any games that dont run on max, sooo I dont really need to push it further. I ran the total war benchmark (dx11 high 1080p) and it came out with an average 52fps
cool thanks for that. So its only a couple fps short (with you 580 at similar clocks of course) Im going to leave it with the current overclock applied and keep playing, I mean testing games Would an unstable gpu oc result in a blue screen? Or just artifacting?
Depends on how unstable it is: artifacting is usually a sign that it's being pushed too hard and you need to back it down a little, but if you keep going from there it's likely to lock up completely and BSOD.
As mentioned above artifacts and driver crashes are normally the first thing u get but if it's really unstable app crashes and also bsod's can happen too, depends a bit on the game or app too. Here is that same single 580 setup pushing a bit more at 965/2050 Never really pushed this card as a single as i only really benched with sli once i got these 3Gb cards, the highest i got my old 1.5Gb 580 stable was 962/2100 but the memory on these 3Gb cards don't overclock so well but it looks like the core will still go a bit higher yet, i think my bottom card is the one letting my sli benchmarks down a bit.
Not sure if you are still working on your overclock but I went through a pretty extensive test a while back. I have 2 x EVGA 480 OC's which are watercooled. I have though decided to keep them at the stock voltage. I also use Afterburner. After several days of testing I found out that my ram was my limiting factor. I am able to run to core clock at 896mhz but the ram will only run at 2030mhz. If I try any more on the ram I get artifacting. With my 24/7 overclock running on my 980X I am able to get a pretty decent score on 3DMark11 scoring P12588 (Linky) I'm interested to see what sort of figures you ended up with.
