My highest stable Base clock so far is 212.5 Mhz with a x19 Multiplier. I was able so far to bump the memory and Uncore divider down with increasing the RAM voltage and decreasing my QPI Voltage. I think having the high QPI voltage made it unstable before, well anyways with that high base clock I can get my RAM to run just about 630Mhz a stick which is not bad, but less than stock. So I decided to have the CPU and Ram overclocked and keep it like so. I have a 3.9 overclock on CPu and a 818Mhz per stick so 1630ish Mhz running on ram which is still a nice overclock from the stock 1333 rating. Ram is running at 1.62V Cpu is running at +0.200 V, which makes 1.376, QPI is +.0.210V, CPU PLL is 1.84 and IOH is 1.10 and OCH is default 1.50V. I think it is better to have both CPU and RAM overclocked, since when I run RAM at stock speeds I can only get my CPU to go to 4.1Ghz, which is not much from 3.9Ghz I now have. I am going to try and Micky mouse some type of RAM cooler like the Corsair one, with 2 80mm fans, but I am unsure of how to mount it, maybe it might left me get a extra Mhz or 2 from the base clock. I also tried loosening my RAM timings to 10-10-10-38 and got no where at all with that. There are pics of my highest base clock and my current settings.
