Asus P5K-E BIOS 0802 update

Cuchulainn · 12 Oct 2007 at 10:22

For anyone overclocking thinking of updating the BIOS of your P5K-E WIFI/AP to 0802 my advice to you is don't at the moment

Post-flashing yesterday I lost any sort of stable overclock over 2.8GHz on my Q6600 regardless of voltage tweaking, multi dropping etc etc etc.

Also, the vcore seemed way out - 1.45v set in the BIOS equated to 1.30v actual which, even taking vdroop into account, seems rather excessive! And of course, that's without any of the C1E etc features enabled.

Luckily I managed to flash back to 0602 and I regained my rock solid at all times 3.2GHz with ease.

I was still on 0503 without problems but decided to installed 0802 yesterday and was running fine for 3hrs, then whilst downloading it just rebooted then it all started. First it kept rebooting once it got into windows so I decided to test the ram and all was fine so I flashed to 0602 but kept on getting Cmos Checksum Error so I did the jumper reset but when I switched on the PC fans, drives where running but my LCD did not turn on nor was there any beeps

so i reset the jumper again and still nothing so I remember the problem people were having with the P5K after flashing to a new bios and they had to pull out a stick off ram and so I did and it posted hooray!! I then said **** it and flashed back to 0503 stuck in my other ram loaded my Asus OC profile looks like its back to normal.

I contacted Asus about the problems I'd had, and they replied saying it was a beta BIOS and still very much under testing. I'd say

Not sure what 0802 supposedly improves either?

Glad you got your system sorted again mate anyway.

Will this work on the P5K SE?

I believe not.

Cuchulainn is the 0602 as stable as 0503? I wish Asus would say what fixes where made on these Beta Bios.

It seems a little more stable to me. I'm absolutely rock steady at 3.2GHz / 1.3625v vcore (My q6600 has a silly VID of 1.325 sadly, so it needs a bit more oomph than most it would seem).

I had no issues with 0503 either. As far as I know 0602 introduced further compatibility with future CPUs. Quite what that means is another thing altogether

0802 is rubbish though. I've been reading elsewhere that the vcore setting in the BIOS is totally borked - almost .1v out, but variable, which is not good...
