Well guys I just hit 4.0 on my 955 not really happy about the Memory aspect but here is a before and after pic.

OC…
CPU Clock Ratio - x16 - 4000
CPU NB Freq. -x9 - 2250
CPU Freq. - 250
HT Link Freq. - x8 - 2000
Memory Clock - x4.00 - 1000

CPU voltage is set at 1.425

My only other options on the RAM were x5.33 which gives me 1332 or x6.66 which gives me 1666 but if I set it to either I get BSODS.

I haven't ran a long test on LinX I will soon temps reached 53c max which is a little high for me but still decent for air cooling.

If you're willing to run hotter I believe putting more volts on the CPU-NB will let you run at 1332 mhz speeds.

Also my ram hated some dividers especially when I pushed my FSB.

Good luck and wow, I couldn't great 4 ghz no matter what (but than I was going for 2400-2600 NB freq).

I think I can get 2400 NB Freq but last time I tried to OC this rig it didn't like some numbers.

I know it didn't like 2600 NB freq and I tried 16.5 for the CPU which would give me like 4125.0 and it crashed so I think until I get some water cooling 4.0 will be ok.

I just think my RAM is under clocked being DDR3 1333 RAM even before I OC'ed it was at 1066

This is my RAM.

If increasing the NB voltage will make my RAM better I might just do that but does anyone know if this is true and how much should I increase it to?
