I had also tightened my RAM timings to 4-4-4-12, but couldn't get it to be stable with anything over 800MHz (using 5-5-5-15). Should I just leave the RAM alone? Yes, probably leave it alone. Unless…..did you try higher volts than the manufacturers specs for higher mhz OC (I think you did)? If you try this route make sure to see if others have done that with your ram and what their results were as you don’t want to fry your ram.

I did find what I believe to be a stable 3.6GHz (8x450 @ 1.42v) OC, but I found it running too hot. I left it on saturday night, and woke up after 4 hours (not sure if it was just because I had to use the washroom, or if the computer was calling out to me, hehehe), and decided to check on it. I found it running at 70 degrees, so I decided to shut it down and revery back to 3.45. I figured the slight gain probably wasn't worth running that hot.

Yeah, and besides, it’s always good to knock it down a notch from your highest stable OC (due to ambient temp changes and just to have a little breathing room for sanity/load temps). I can run my CPU upto 3.4 and did for months but now run it @ 3.0 – 3.2. Other than benchmarks, a difference of .2ghz really does not make that much of a difference for gaming….spend the time on the gpu OC.

However, like I mentioned earlier, since then I have noticed my temps being higher in general. Before my 3.45 temps, on load, were usually around 56-60 (sometimes going up to 62 for a brief second and then usually back down). Now, using the same settings, it's usually at 62-63 and occasionally going up to 65-66. I'm going to chalk it up as the ambient temp being higher this weekend, and test again later when I believe they will be lower. FYI…my load temps vary from 47C upto 51C….all due to ambient!

So that's that. I don't think I'm going to be able to push this thing much further, and if so, I don't necessarily think the gain will be worth the tradeoff. I think I pulled off a fairly respectable OC. Yes you did…now it’s time to enjoy it! I was kinda aiming for 3.5GHz, but would have been happy with 3.33, so I got pretty darn close. I'm slightly disturbed that I wasn't able to get the RAM up to 1066, especially since I had exchanged the Corsair PC6400 I bought for the PC8500, and haven't gotten the extra performance I paid for, but that's something I can live with. If anything, the RAM at least looks like it has better cooling implemented, so I probably won't need to worry about it crapping out. I wasn't able to really get the GPU any higher than my last settings either. Any increase from that point resulted in artifacts, but as you indicated, that was a somewhat respectable OC there. I would recommend knocking your gpu core down to 648…overtime the 660 OC could slow cook your card/especially as dust starts getting into it, etc. But if you plan to replace your card within 1 year or so, then don’t sweat it too much.

The performance speaks for itself. I haven't done full on benchmark testing (yet), but I do recall pre-OC, I would be getting around 20-22 FPS on Crysis using the highest settings available in DX9 (which actually used some of the DX10 settings through .cfg editing), 4xAA, and 2nd highest shadow settings @ 1200x1024 (highest my monitor will go). Now, I'm getting about 31 FPS average using the GPU benchmark utility with all settings as high as I can get (actually, only 8xAA). That’s nice, isn’t it!?! When I first got my rig, Oblivion ran @ 45fps with stock cpu/gpu, now it runs at 65+ in most areas. I use Oblivion as my litmis test as it is the only software I had on my rig before I OCd.

Which benchmarking utility would you think would be the best for me to throw down some $$$ on? I'm guessing Everest?Yes, Everest would be best but also DL and use 3dMark06 or Vantage since it is free and it is the current ‘common’ language by most people here on this board.
Good job man! Glad I was able to help out, with at least moral support. If/when you get a moment, post some pics of your new case and show off some!

Cheers,
Qbert

Hey. Sorry I disappeared without any update... since getting my OC stable, I finally got around to adverting my time/attention to beginning playing Age of Conan.

So, yesterday, to get my latest "fix" I went out and bought a new ATI Radeon HD 4870. I can't even get it to bench higher on Crysis, and I can't even get 36Mark06 to run at all .

If you don't mind checking out my situation, I posted a thread here: http://www.overclock.net/ati/353836-...ml#post4141305

Back to square one, now. Got fed up with my mobo constantly giving me issues, so I went out and bought myself an Asus P5Q-E to have Crossfire support with my new 4870. So begins the OC grind once again.

P.S. Interested in another EVGA 8800 GTS for SLI?
