E8200 @ 4.0GHz (500x8) on a mATX

[TheScavenger]

I just got my board stable after running a series of stability tests and decided I would share.

- E8200 @ 4.0GHz (500x8), BIOS 0506
- Asus P5E-VM HDMI
- Crucial Ballistix DDR2 800 @ 1001MHz 5-6-6-15

- Core Voltage: 1.44V, 1.384-1.400 under load
- FSB Strap: 333
- RAM Voltage: 2.22
- NB Voltage: 1.51
- SB Voltage: 1.20

I can post up the rest of the BIOS settings if anyone is interested.


Please do, just got a Wolfdale and looking for a good baseline of settings.

I used to have a E8400 @ 4.0GHz as well. Which wolfdale did you pick up?

An E8500, and it doesn't like the settings I ran my E6850 at (obviously lowered the vcore significantly, but I must be missing something else).

do you need 1.42 FSB Term voltage for 500FSB ? Tried lowering it ? with my E8400 or 8400 both at 500FSB too I only need 1.25 1.3 to get them stable... on P35 P5K Dlx and P45 P5Q Dlx mobo... these CPU sometimes behave erratically when pumped with the wrong voltages

[Kilyin]

Here are my E6850 settings... currently all the same except the vcore which is now 1.375 (1.36 in Windows with loadline calibration enabled) and FSB Term is 1.3.

My memory has failed tests at these settings when it was perfectly stable with my 65nm CPU and the exact same configuration. Also getting a lot of blue screens.

Been doing a bit of searching and I think I might try lowering those GTL voltages... see if that helps.

EDIT: this is with 500 FSB and an 8 multiplier.

I'll give it a try. Thanks!

kilyin, what is your real pll? i know on most asus boards ive tested there is a pll overvoltage, and a Huge vFSB drop.

[TheScavenger]

What MB are you using, Kilyin?

[Kilyin]

How do I tell the real PLL, with a multimeter? I'm using a P5K Premium.

[Leeghoofd]

Only way to find out is indeed via multimeter... Did you try eg CPU PLL 1.5 and FSB Term 1.3 ? to exclude CPU voltage drop multi to eg 7x... You got 4gb of ram Kilyin ? also what you could try is to disable Transaction booster and set relax level 0-1

2 gigs of G-Skill right now, might upgrade to 4 gigs. FSB Term is 1.3 atm, I'll try the CPU PLL.

On another note I dropped both GTL voltages to 0.61 and no more instability or blue screens so far. I find it really odd that GTL voltage that doesn't affect my RAM was causing me to fail memtests, but it had to be, since that's all I changed. These 45nm are definitely much more sensitive procs than the 65nm.
