Overclocking RAM question

post #1 of 4
Thread Starter 
Hi,


I'm attempting to OC an e6600 with PC-5400 OCZ Gold RAM. I have a couple of questions. On the p5B-d motherboard my DRAM frequency is set to 536Mhz while my CPU frequency is at 268, does this mean that, i can up the cpu frequency until my ram reaches 667 without using a divider?

Moreover, i can change the dram frequency to say 670, im guessing this would overclock my RAM is that true?

thanks

Basically, you're running a 1:1 ratio and with that OCZ ram being at 333mhz the stock speed, you will certainly hit a 333mhz on a 1:1 ratio and the CPU will be at 3.0ghz easy, well, actually is a 334fsb ratio. Here, I'll show ya:

__________

Since that you're going to run a 1:1 ratio, in that pic the RAM shows at 1000mhz but in your case, if you do the 334fsb, then the RAM should read: DDR2 668mhz.

Your timings should be 4-4-4-12 with a 2.1v. I guess, if that's the stock timings and voltage for the OCZ Gold you have there.

Ok, my CPU frequency on the first Screenshot that you showed me is 300 this is without any increases in Vcore, just by changing the numbers there and rebooting.

the ram is showing at DDR2-600MHz
my RAM timings are at CAS-5, RAS-to-CAS-6, RAS Precharge-6, RAS activate to precha 15, donno if i should modifiy these or not,

I am overclocking right now live, and posting from this laptop, how should i proceed in overclocking further, temps are 32/44 idle/load but when i changed
cpu frequency to 310, the bios locked up.
how do i proceed from here

EDIT: Vcore is at 1.328V

Just do the same I've done so far with my OC in those 3 pics.

Except! The RAM part, where mine reads 4-4-4-8-4-30-10-10-10-. Yours should be left to the default value for the last 6 value settings. So 4-4-4-12 for you with a 2.30v on a 334mhz 1:1 ratio.

VC: AUTO.

What BIOS version you have? Best are 0711 IMO.
