GTX 260 216 overclock
I ordered this GTX 260 today for $145 shipped after $10 coupon code EMCLSNT35. (Newegg newsletter subscription required to use the coupon) It will be an upgrade for my son's 9600GT.
I will overclock the GTX260 and compare with my HD 4850 512MB (@850/1200) and post the results here. If GTX 260 is much faster than that my son might get the ATI instead
Has anyone overclocked this thing and how much? I would appreciate the info. Thanks!

It can very rarely run Crysis GPU benchmark for 3 loops, and something very interesting happened the two times I could complete out of many trials. GPU temperature went upto 85C in the first successful test and it was max 55C in the second; scores were very similar, 42fps @ 1680x1050, DX10, high, noAA. I checked the temperature by touching the card as well, it was burning my fingers in the first test and barely warm in the second. Very puzzling .... but this is a faulty card anyway.
Here are my HD4850 Crysis GPU test benchmarks but I will not say it beats GTX 260 just yet.
850/1200
Run #1- DX10 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 45.065
Run #1- DX10 1680x1050 AA=4x, 32 bit test, Quality: High ~~ Overall Average FPS: 35.17
625/1000
Run #1- DX10 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 36.34
Run #1- DX10 1680x1050 AA=4x, 32 bit test, Quality: High ~~ Overall Average FPS: 28.82
System configuration:
CPU: Q6600 @3.3GHz 9x367
RAM: 6GB DDR2-733
MB: P5Q-SE-PLUS
OS: Vista64
Here is the requested info.
I am running Windows 7 (7100)64 bit
EVGA GTX260 core 216 ( OC'd )
Q6600 @ 3.2
and a screenshot for your viewing pleasure.
side note: it was running 37ish fps at stock clocks.

WOW!!! Thank you so much, you are quick again I will use your benchmark as my reference since we have very similar systems.
I will be able to post my benchmarks next weekend. I can't wait to see how much it will overclock. Nevertheless, the overclocked HD4850 (see above) performs admirably. Don't you think so? I already transferred the HD4850 to my son's PC and I am using the broken GTX 260 for now
I just noticed you were running the 32 bit test so I reran it.
Run #1- DX10 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 45.25
That was at the same OC.
And yes that 4850 runs pretty good.

Scott, thank you again! This will be great help for me. 725 is a very good overclock :thumbup, that would be a dream overclock for me. You are using the stock cooler I assume. How is the temperature while running the benchmark? BTW, is your GTX 260 a 55nm part or 65m?
It will even run OCCT gpu test for over an hour with no errors at those speeds.
In OCCT the max temp it reached was 71 but the benchmark never got it over 66 (with the fan at 100 ).
It is the stock cooler.
It is 65nm.

Here are the results using Crysis GPU benchmark
579/999 (Stock speed)
Run #1- DX10 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 41.44
Run #1- DX10 1680x1050 AA=4x, 32 bit test, Quality: High ~~ Overall Average FPS: 35.185
700/999
Run #1- DX10 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 46.545
700/1100
Run #1- DX10 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 46.695
700/1200
Run #1- DX10 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 46.77
675/1152 (SSC speed)
Run #1- DX10 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 46.73
I will keep the card at SSC speed from now on since 700 GPU clock was not stable with Vantage. An interesting observation is about the ineffective memory clock. If you check the results above, you can see that memory overclock is not improving the performance at all.
I wish my Gigabyte board had SLI. I would buy another one if could justify it for gaming and folding. They are pretty nice cards for the money.

I did play with the EVGA voltage tuner..
I locked my machine up several times Some pretty cool artifacts too !!
I could not get comfortable with it. I un-installed it.
Scott
So I should not worry too much about my inability to run voltage tuner with a 55nm card.
Run #1- DX10 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 47.214
The GPU temperature saturates at around 60C with fan speed set at 61% (2000rpm) while running the Crysis GPU test for 10 cycles.
I wanted to start ramping up the fan speed at lower temperatures than the default 65-70C to keep the overclocked temperatures lower while running the fan at default 40% in 2D mode. EVGA Precision tool's profile based fan control was not exactly the way I wanted to do this. I wanted to control the automatic fan speed parameters to control the fan speed instead of defining speed-temperature steps in pairs. I switched to Rivatuner and used the low-level fan speed controls for that. I just changed the T_min and T_lowlimit values (as shown in the second picture) to 45 which were both 65. The results are summarized below in two temperature monitoring graphs with and without the modifications (left and right, respectively) in the low-level fan control while running the Furmark test after temperature saturates. The maximum temperature was 77C before the modified fan speed control and 67C after modification which starts to ramp up the fan speed at 45-50 instead of 65-70. This is, IMHO, easier and more effective than using Precision tool.
Note: For Rivatuner to restore the fan settings after suspend mode it should be running at the background. So check the "send to tray on close" and "run at Windows startup" options in the Settings tab.
