Default P5E and Mushkin PC8500

Latest 702 bios, 2x2gb sticks of ram, which has passed hours of memtest. The site states the board supports 1066 and the option is in the bios, just that particular brand isn't listed.

It runs beautiful at 800mhz with 4-4-4-13, but even with timings at default 5-5-5-16, anything at all above 800mhz renders the board unbootable.

I thought I read somewhere it's supported as long as it's obtained through overclocking, but I don't want to overclock until I figure this out.

Any suggestions guys?

Thanks much in advance.

Try the 333 strap in bios. Also the Vdimm is off by .5v so if you want 2.1v set it to 2.04.

EDIT: try 9x400 3.6 / 400 strap and set the ram to 1066 5-5-5-15 |CPU @ 1.28 to 1.30 vcore | NB @ 1.4 | FSB @ Auto | SB @ Auto.

YVW, let us know how it goes dude. That should be a pretty solid 24/7 setup.

I'm at 365x9 right now and my vcore shows 1.32 in the bios HW monitor, 1.36 in cpuz, but I stilll have it in Auto. Is this normal? My P5K didn't raise vcore like that.

Even at 365x9 I can't get it stable. It has to be a vcore or vdimm issue.

365x9/DDR2 867 vdimm1.9/5-5-5-15

I tried with the vcore at the auto setting and lowered to 1.2.

I'll wait a bit, don't want to damage another one.

EDIT: Think I have it figured out. I was setting vcore way too low, even after you warned of the difference.

Grey a lot of the time setting the CPU Vcore , NB and so on manually will put you in the ball park. Most of the time setting it to Auto will set it to high or to low. How far did you get?

I got to 375x9 fsb, 1.2 vcore (actual), 2.3 vdimm @ 10 something..don't remember exact, using your timings. I didn't touch the NB though, here's why..

I kind of panicked after several bsods and a couple no posts, reset everything to default and still got random bsods. I was thinking bad ram in spite of memtest and the fact it worked fine @ 250x12 on my P5K. But now I'm wondering if it's driver conflicts. I didn't reinstall Win after swapping boards, because according to [H] and..I think it was anand, the drivers Asus uses for both chipsets are identical.

I uninstalled all drivers/devices early this morning, registry editing and all, now I'm stable at default, using Orthos anyway. I think I may just break down and reinstall Win tonight to be sure...crapload of apps on there though .

EDIT: More bsod fun just surfing the web. Reinstall time.

Confirmed: This board does not like this Mushkin ram.

Time to order more.

This board likes G-skill and Corsair, I have run both. Vcore = cpu volts | Vdimm = ram volts.
