Asus p5e and e8400 woes

Sweet thanks.

I heard something about the P5E needing low class memory with low voltage to start then set the voltage for your crucial and use them

This is nothing new, neither for Asus boards or many other brands. If the BIOS is set to only 1.8v (normal default), then chances are good you won't be able to boot with RAM that needs 2.2v to operate properly.

I've been lucky in the past with older revs of Crucial Ballistix DDR2 (800 & 1066), with some sticks booting fine at only 1.8v. Seems the newer rev(s) of Ballistix are not as "sweet" and take a little more juice to run at their rated specs. Not surprising, considering how cheap they have gotten ... heard rumors that some sticks don't even have D9 IC's.

Hey guys i just ordered a old celeron to get mine up and running. I saw a review for the P5E and the guy had the same problem as me and said just get a old celeron in there and flash the bios the put the E8400 in there. Think it will work?

Yep that did it for me...

I have a problem similar to this.. got a new P5E Motheboard with a E8400 cpu. Got it all set up with vista, then finally got to where I could do the flash update from the internet. Thought I needed 0203 (yep, later i rechecked and it was 0303 I needed, ARG!) for the unrecognized cpu message at bootup. Flashed it, everything verified okay, rebooted... no post. nada..

My question, if the bios is merely at a point where it won't recognize the cpu now, will I get the no post thing where I get no dos prompt, no video, no bios access, it just sits there with the green motherboard light on, the dvd drive whirs a little and the light blinks for about 5 seconds, then it just sits there with the fans (cpu and case) going merrily away, mocking me.. or is it definately my bios is screwed? It never gave me the chance to go in and save defaults, the 1st time i restarted after flashing from windows, said situation as described above. I'm going to call a local repair place and see if they can help me.. about ready to just ship the mobo back to newegg and get a replacement.

Any help is appreciated.. dammit and it was working fine till I "fixed" the bios...

Oh yeah as for cpu and memory what are the absolute cheapest ones I can try to at least let me flash it to the latest bios? I THINK I need a 775 socket cpu but not sure how far back this p5e will go for cpu compatability... and the memory has me stumped unless crucial has cheap memory listed for this board..

The key for the memory is to just find something cheap that runs happily at default voltage, ie. 1.8. The problems arise when you have high performance memory that won't run at such a low voltage (despite tweaking) and a motherboard that doesn't like higher voltages much above 1.8. Like I noted, Crucial says Asus is bad about this right now, and don't even think about an Intel mainstream DDR2 board - they specifically state not to use memory which requires more than 1.8v.

Ahhh, my problem didn't seem to be the memory, since the system ran great for about an hour and a half, right up until I flashed it "back" I guess to 0203... damn, I KNOW it said 0203, then when I went to their website, it said 0303..

yarg...

Thanks

Maybe Asus could have something on their webiste how to handle the situation of vendors still selling boards with 10/17/07 bios. I've had the identical problems and more. e8400. p5e, corsair dominator DDR2800 2.4V 3-4-3-9. I bought a Pentium 4 631 Cedar Mill for $67.00 and a $15 stick of DDR2 667 256 MB flased to bios 601 and got the boot (finally). But, the Corsair memory refuses to boot even after increasing default voltage to 2.4. Neither module boots. Unknown what to do next?
