I'm building a new system soon and I've pretty much settled on the Asus P5K-E WiFi and an 8400 processor (looking at my sig you can really see I need an upgrade). My only question though is, if I get a board with an older bios that doesn't support the new 45nm processors will the board still POST with the 8400 so I can flash the bios? This is the only thing holding me back from purchasing the 8400 over the E6750. Any advice will be much appreciated.
 
Unfortunately, no. If you get an older P5K-E [with an old bios], it won't boot to let you update the firmware.

If you buy from a volume retailer like Newegg, you should get a P5K-E with a newer bios.
 
I just built a PC with this motherboard and I want to say it came with the 0806 Bios (Ordered from Newegg). The PC was constantly Blue Screening during installs, and eventually in windows, when I updated to the most recent bios version from the site everything seems fine now have not seen any blue screens.
 
I'll order my parts from Newegg so hopefully the P5K-E will have the updated bios. Now if Newegg would just get the E8400 back in stock.

Thanks for the info guys.
 
mwave.com has the e8400 in stock... just ordered for $218 plus shipping...

I just ordered one last week. It came with the 0906 bios which is not the most recent, but it does support Wolfdale out of the box.

I downloaded 1006 bios today & have been playing with it.

Unfortunately, it seems as though my chip just doesn't want to hit 4Ghz, at least not at the voltages that I feel safe giving it.

All P5K-E WiFi BIOS revisions after 0906 (100*) are beta, of course the MB doesn't come with one of those.

Just went back & looked: http://support.asus.com/download/download.aspx?SLanguage=en-us&model=P5K-E

I thought only the 1006 was beta, as 1004, etc didn't say Beta, but they also don't say "release bios"!

They need a more uniform way to label their bios's. As the other non-release bios's should say beta. Though I think its just a matter of time before they'll revise 1006 to a release bios, its seems to work better for me than the 0906.
 
Is it possible to downgrade to 906 if 1006 is causing problems? Before 1006 I had no problems going 400 but now XP get page fault BSOD at 400 on 1006. At 1006 Bios, it is stable at 333 but I havent try any other frequency.
 
You'll need to use an override switch in DOS I believe.

You know like after the DOS flash command.... something like A:>flash.exe biosname.rom /o
/o - just an example, I don't know the exact command.

If you're getting a blue screen its probably your memory.

Try loosening the settings for ram.

Set FSB strap to 400,
Disable that first ram option (above the timings section)
try loosening timings to like 5-6-6-18
set vdimm to at least 2.1-2.2v
Increase NB voltage, etc.

Do several things to see if you can get it working, then you can try to tighten things back up gradually.

I received my Asus P5K-E this week, and it clearly states on the Box that it Supports 45nm CPU's. Now if you we're going to get a P975, P965 Chipset Board, they might or might not.

The E8400 went from $209 to $272 at ZipZoomFly, and chased me over to the E6850, which has started to come down in Price. When the E6850 was going for 300, it was not such a great deal, but I got mine for about 250 and wanted out of the Box Compatability, and was more concerned with Stability, than OverClocking.
