Oc'd Q6600 But Issue With Ram Speed...


Recommended Posts

I'll mention up front this is my first attempt at ever overclocking anything.


Start with my specs:


Intel Q6600 G0 @ 3.2ghz (400 x 8)

Biostar Tpower I45

Radeon HD 4850 @ stock speeds

2x2GB OCZ DDR2 PC2-8000 Platinum Edition Dual Channel (800mhz) 1:1

Arctic Freezer 7 Pro

Antec 900 gamer case (4x 120mm, 1x 200mm)


I've got my system stable at the above settings, CPU temp at idle around low to mid 30's and mid 60's under load.


My issue is that if I understand correctly, my RAM is designed to work at 5-5-5-18 @ 1000mhz.

I have the issue to set 100mhz in my BIOS but I cannot boot into windows with my memory at that speed.

I have manually set the timings to match the specs but still won't go.


Here are the volts I have recorded from BIOS (most recent version).


CPU V: 1.472

DDR V: 2.096 (specs on RAM is 2.1)

FSB: 1.328 (auto volt)

NB/SB V: 1.232 (auto volt)


If I am correct that my memory should be able to run faster then how do I get it to do so?


If there is more info that is needed than let me know.

Try it with the CPU at stock speeds, and put a drop more voltage through the ram (like the next step up in the bios)



OK, I went back to 267x9 and the closest w/ multiplier I could get to 1000MHz w/o going over was 890MHz.

Tried this with 2.144V on the RAM and no boot.


IDK which combination I used but I know a day or so ago I was booted with 1000MHz on the RAM but it failed on OCCT after about a minute.


If I let the computer boot with all default BIOS settings it will boot with 5-5-5-15 and 800MHz on the RAM.


Any other ideas? If I put any more juice into the RAM then it will void my warranty...

RMA time i guess, if it wont run at it's rated speeds then you need new stuff.


I just got the RAM upto 962MHz. It ended up liking the auto-detected 5-5-5-15 over the 5-5-5-18 timings...

962MHz might be enough for me to hold onto the sticks, next divider above this one is above 1000MHz and is not happening.


It seems to be stable at this point but I have to give it a real good test.


Which of the two settings if they both would run stable would give me the best performance for games and just using Vista in general?

Would going over 400 on the FSB not be advisable if i'm on air cooling?


FSB: 400

Mult: 8

RAM: 962MHz




FSB: 450

Mult: 7

RAM: 900MHz
