August 9, 200916 yr I had some time on my hands to play around with my computer this weekend and have come up with a different config for my OC on my i7940 and wanted to pass it along. Since I have built this i7 system I have been running at 4.05 GHZ OC with my ram never running full speed do to the way all the multiplyers worked out. I have the EVGA 260 superclocked edition VC and understand it may not be the perfect match for a i7 with a high OC but never the less actually do get great performance out of it maybe due to the fact it is the Super Clocked version. Anyways that being the case I began thinking about all the posts I have read about matching it all up for best performance so I thought I would try to down clock the CPU a bit. At 4 GHZ I could in no way shape or form go any higher at all and be stable in OCCT. I did find that 3.8 was extreemly stable. I also found that I am able to run a 200+ BCLK which would allow me to run my ram at spec speed @ 1600. With all that I then started playing around with odd numbered multiplyers as I have read in several places that the 940 seem to like them better which I can confirm is 100% true in my case. THis is what I ended up with after several hours of tweeking the BIOS.CPU Ratio @ 19BCLK @ 206 = a 3.93 GHZ clock speedDRAM Frequency @ 1651 = a slight OC on the memoryUCLK @ 3304Spec Ram Timings @ 8-8-8-24VCORE @ 1.29375 = very happy with this settingQPI @ 1.325DRAM Voltage @ 1.66My sim actually runs much smoother that it did at 4 GHZ and my ram is now running at rated speed.Bottom Line is I can run Very Smooth locked @ 30 FPS with Max AutoGen/Max Scenery. Yes I could run with that before but with Max AutoGen it was a bit jerky so I ran 1 notch down. THe next Huge plus to this is I was able to lower my CPU Voltage way down and also get my ram running a spec speed with a small OC on it as well.Now if you will excuse me I have some flying to do. :( Jim Wenham
August 9, 200916 yr Thanks for sharing :( Next weekend I'll replace my old case and CPU cooler. I now run my i7 940 at 3.5GHz due to an insufficient cooling.
