Where in bios do you set the CPU/RAM ratio? I need to change it to 1:1. I tried looking through the manual but I didnt see anything.

Thanks!

You can set DRAM Frequency in the BIOS. Available DRAM frequencies are based on the FSB - the end result is the same as changing CPU/RAM ratio.

Got it. Thanks, man. Changed to 1:1

With a E6600 and Asus P5W DH DELUXE.. i can get the OC to about 3.15 stable... if I take it past that to say.. 3.24 (360 setting in bios) it wont post when I restart. Shouldnt I be able to take this higher with this set up?

I am using an ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler. Case has plenty of ventilation. In fact, I just switched cases and its running cooler than it ever did with my Thermaltake. Any ideas?

Actually I just managed to get it to 3.6. VCore is around 1.45. Max for this CPU is 1.5 according to what I have read.

One odd thing, it seemed like once I passed 3.4 or so.. the machine actually started to move slower. At 3.4... The green vista bar that appears at boot up (that fills from left to right) went by about 5 times. Once I crossed this point it takes almost twice as long for it to load.

Also, once I get to desktop, the machine seems to take longer to load my icons/default programs. Is this normal if it is taken too high? Maybe I should set the RAM to a 1:2 ratio and decrease the FSB?

Memory at 1:1 is fine since it now runs at 800. On the other hand, your CPU might be slowing down to save itself. Back down the voltage and run it at 3.4 if it's stable running Prime95.

If I back down the FSB the memory is recognized as PC-5700 instead of PC-6400 at post since its a 1:1 ratio. Will this make much of a difference? Thats why I was going to try a 1:2 ratio.

Manually change it to PC-6400 (or whatever is closest at that FSB).
