help e6600 can't pass 2.52 ghz

post #1 of 17
Thread Starter 
system specs are below. i've been able to overclock using msi's DOT, and it worked perfectly so far, but now im trying to get it higher

but when i try to do it manually i can't get pass 2.52 ghz

fsb is set at 280 but when it reaches 282 fsb it locks up and BSOD.

default voltage is at 1.17 i've tried going as high as 1.195

what is the max vcore?

how come i can't pass 280 fsb

You need to really increase the vCore, stock is something like 1.3250v. You've got a lot of breathing room.

Intel says 1.35v, but users here with sufficient cooling regularly push 1.45v - 1.55v on air.

OK for one your running a 6 multi when itshould be 9. You need to disable speedstep or eist basically all the cpu extra funstions in bios. That will brong it up to the 9 multi.

That mobo should do ok, not the best ocer but still should do 400fsb plus I imagine.

I would disable all the cpu extra option sin bios and set vcore to 1.325 to start out with and check your temps under full load. Then start raising yourfsb


Edit: sorry didnt see that you stated 2.52ghz so under load I assume it jumps up to speed. Still disable all the extra stuff and you should be good to go. Also set yourram 1:1 with losser timings to get it out of the equation

What memory ratio do you use? Show us a screenshot of CPUz Memory tab.

Yep your Vcore looks like the problem

Also if it still locks up at 282FSB, try just jumping to 300FSB

Some boards don't operate at certain FSB's kind of like a wall you need to jump over

ok well i have intel eist disabled (there is no option for speed step)and yet the multiplier keeps flipping back between 6 and 9.

also i have the fsb to dram ratio put on linked. (options are auto, linked, and manual). im not sure which one to select.

well i quit all that crap software for overclocking and i've decided to just do it in bios.

this is my current setting below.
how do i achieve 1:1 fsb:dram ratio?

EIST as well as C1E need to be disabled. Go back and check to make sure both are disabled. That should solve the issue of the multiplier/voltage ramping up/down.

As for the FSBRAM ratio, lets use my cpu/ram as an example
E6600 (266FSB, 9multi stock)
Corsair DDR2-800 ram, 200MHz stock (also quad pumped)

So, in my bios, I just drop the memory frequency until it shows 533 (which is 2 * 266, or a 1:1 ratio).

As for the max, you just have to test and see, trial and error is the name of the overclocking game.
