Well if you aren't seeing crashes in what you're doing then it's stable enough. Like I said, all chips are different, and you seem to have hit some sort of binning motherlode. :P
Are you sure that's 100% stable, even under say 2 threads of full load rather than just 8? That seems like impossibly low voltage; I have to get about 1.288v full load on my 2600k to keep 4.2GHz fully stable. At ~1.25v it takes hours to actually crash under 2 threads and may never crash under...
For what it's worth, I've used every single AMD driver release since first buying my 4870 over two years ago, and I've only rolled back to an older one ONCE, and it was when 10.3 or 10.4 (don't remember) came along while I was playing through Crysis and ate about 10% of my framerate. It was...
Last I had heard was the same as you, the 6990 is due in "late Q1 2011," so I would expect it sometime in March.
A dual-GPU variant of the GTX 580 would almost assuredly be impossible, as the TDP of a single PCI-E card is theoretically limited to 300W by the ATX specification, and a maximum of...
The 6970 uses higher-voltage RAM with tighter timings than the 6950. Using a modified shader-unlocked 6950 BIOS, it's impossible to damage the VRAM without overclocking. Using a 6970 BIOS, however, could potentially cause problems.
Edit: Which I see now is probably exactly what you're saying.
At the same voltage, my maximum fully stable core OC at stock shaders was 925. Just because your card got a substantially higher overclock with stock shaders doesn't mean everyone's will, and just because the games or applications you use today don't benefit much from the extra shaders doesn't...
I posted in the other thread as well so I won't repeat everything I said, but the short version is: Gigabyte 6950 2GB, modified 6950 BIOS + overclock to 915/1375, stable and no artifacts for a week.
I've been running my 6950 with the shaders unlocked, overclocked to 915/1375, for about a week here with no issues whatsoever. I did my research before blundering in and took every possible precaution. I used a shader-unlock mod of my VBIOS rather than just using a stock 6970 BIOS (so memory...
Personally I'm going to wait a couple of weeks and let the SandForce controller do whatever magical garbage collection it's supposed to do and see if performance improves. Either way, it's still a TON faster than even my 1TB SpinPoint F3 at random read/write performance and seeking, and that's...
4.3 GHz, Windows 7 x64: 28303
If you don't mind my asking, what voltage do you use for your OC and what kind of load temps do you see at 4.9? I have a 212+ as well and am interested in seeing if I can push a little further.
I'm in the same boat. For comparison's sake, I ran (or started to run, rather) the same benchmark on my 1TB SpinPoint, and I think the difference in sequential write performance speaks for itself. (Though it's somewhat comforting to see that the SSD is at least running circles around the HDD...
