hey bud great forum on the overclocking my question is i got my i7 930 to 3.6 ghz witch seems like a safe OC my only question is my ram is running at 764.5 mhz is this normal? in bios i have ram xmp on at 1600 mhz just want to make sure im not bottlenecking my ram i have 12g corsair dominator
764.5mhz is a reading you got from cpu-z i assume? You can double that number to give you your actual speed so 764x2=1528mhz which isn't unusual when overclocking. The ram speed is equated with this formula...
memory speed= bclk x memory multiplier
or as an example.... 1368 = 171 x 8
If you have the ram settings at auto using xmp profile it will adjust according to your bclk, that's how you get your speed of 764.5 x2 = 1528mhz.

Didnt see this before I replied.
Your ram speed is actually 539.8 x 2 = 1079.6mhz
A couple things, you can try using the x21 multiplier instead of 22. This might make your overclock more stable as you go higher. So in BIOS lower your multiplier by 1 which will probably look like 20x in BIOS (intel turbo boost enabled adds +1x multiplier in windows). So recalculate your bclk to get you the desired cpu frequency. If you want 3.9ghz cpu then 3900/21=185.7bclk or 186bclk.
You can keep using xmp or start to set your ram manually to give you the timings you want. Or just leave the ram to auto and manually set your memory multiplier to 8 istead of 6 which will give you 1488mhz (which will look like 744mhz in cpu-z).
Showing your voltage settings would help if you want to know whether or not things are safe, or showing anything you have modified in BIOS for that matter.
alright these are my new setting raising ram seems to be running good no bsod going to run prime95 over night my system temp at 38 deg c and cpu temp at 34c seems to be ok thnx for ur help if all goes good gonna try to raise blck more tomorow
