E6700 & Asus P5B Dlx. @ 3700 MHz. on air!

post #1 of 13
Thread Starter 
I was just messing around today and was able to OC my E6700 & Asus P5B Dlx. from the stock 2666 MHz. to 3700 MHz. on air.

Settings:

370 X 10 = 3700 MHz.
DDR2-740
1:1 Divider
Ram Timings, 5-5-5-12-6-35-10-10-10-10
Ram Volts, 2.25
Vcore, 1.528

Temps: 45c & 46c Idle & 60c & 61c 100% Load with TAT.

One thing that I can't understand though is the fact that I have to run my Ram Voltage at 2.25 running @ DDR2-740 Ram speeds, that isn't even the stock 800 MHz. ( Whats up with that, any ideas?)

( I can't wait to get my water cooler! )

Since you're on a 1:1 ratio your RAM speed is simply twice your FSB.

FSB - 370
RAM - 740

If you lower your multiplier to 9, have your FSB set to 400, your RAM would then be at 800 while running at a still speedy 3.6 GHZ. Might be able to make the most of such a high volatage that way perhaps. May or may not work out for you.

Plus your temps would probably drop just under that 60C mark too.

Yea, I understand that but what I am saying is that the Ram shouldn't need that high of a vlotage to run under the factory speed of 800 MHz. ( right?)

When your system is at stock speeds have you tried adjusting just the RAM itself to 800? If so, does it require that much voltage to do run stably?

No it dosn't need that much to run at DDR2-800 at 2666 MHZ, but it needs 2.25 to run at DDR2-740 at 3700 MHz.

yep is called vDimm droop...the P5B Deluxe voltage readings in the mobo/bios are way off of accurate. I will say this though thats a fine OC on 1.528 BIOS set vCore. Now if that actual vCore then thats pretty much par for the course.
