FSB wall at 430 (using e6600)

post #1 of 12
Thread Starter 
i have seem to hit a wall at a FSB of 430.

im using a e6600 and a P5W dh with corsair xms2 ddr2-800 ram (1gb (512mbx2))

everytime i try to push my fsb more than 430 windows wont even load.
my bios settings are:
cpu freq: 430
ddr freq: 635? (i forgot what it is because its not 1:1)
vddr: 2.15v
vcore: 1.425v

cpu multi: 7 (default 9)

pci-ex: 100
pci sync: 33.33mhz

ram timings are loosened to 5-5-5-15 (4-4-4-12 for 800mhz)


its under a zalman cnps9700led hsf. havent checked temps yet, but im quite positive idle temps are mid 30C.

well if your ram is running 1200+mhz thats probably part of the problem. 635x2=1270. Ive heard of a wall with that board but I have no hands on with it so cant realy comment on it.

How about the rest of the settings in the BIOS?

Like performance mode and there's a couple more features that it may require you to disable them.........HyperPath 3......can't think of which else but those need to be disabled and set to normal when OC'ing at the speeds you are at now.

Also, for the Corsair, see if you can set the Vdimm to at least 2.20v or the max 2.30v because 2.15v is weak. And set your ratio to 1:1 or 4:5.

the rated voltage for my ram sticks is 2.1v

and how will i go about getting a 4:5 ratio?

ive already disabled hyperpath3 too.

Rated? Nobody here goes by that.......push it!

Set the Vddr to 2.20 or 2.30v in the BIOS, that's how you set it to.

How you get a 4:5? Never mind, I'm afraid your RAM will not be able to handle that so use a 1:1 ratio and that's easy.

Say, if you're running a CPU frequency of 430, then your RAM should read DDR2 860.

Now, just so you know, some of the XMS2 DDR2 800 CAS4 are known for knot overclocking that great and also I hear that they don't like high voltage, so you'll have to try and see which way your RAM goes.

And don't use anything else besides a 1:1 ratio. With the 430 for CPU Freq and DDR2 635 sounds like you're on a 5:4 ratio or something where the CPU is running faster than the memory, which is a no-no.

alright ill give it a try.

because right now im on a 410FSB.
CPU is at 3.28GHz (multi 8) and RAM is at 820mhz with 4-4-4-12 timings.

usually i cant even pass a fsb of 410 on a 8 or 9 cpu multi.

up your chipset voltage and put better cooling on it

ICH is the South-Bridge.

I'm still saying it needs more Vdimm.
