Official ASUS X38 Boards: P5E, P5E3 - Info/BIOS Thread

[Aleslammer]

BIOS 0903 is still listed here: ftp://ftp.asus.com.tw/pub/ASUS/mb/socket775/P5E/

I got the 0903 bios for the P5E but in EZflash 2 the bios it´s not recognized , what is the best way to update the bios since i cannot update from asus update utility because i got vista 64bits .

Cheers

I allways flash with the bios flash feature.
You must use a pendrive formated in FAT32, put the bios file you want to flash in it, reboot and enter the bios.




Enter the tools tab


Use ASUS EZ Flash 2, than chose the bios you want to flash.

First Prime run on a E8500 with BIOS 0903, air temp in the room was 29C at the time the screen shot was taken so Ive got a little more play room.

(Correction) TjMax should have been set to 100c in CoreTemp for the E8500 per latest info from Intel, so my temps are to low by 5c in the screen shot.

I know some people don't like the risk but its simple and safe to do.

I tried my self and the results are great

I flashed my P5E with 0407 Rampage Formula bios and its a lot more stable and has more bios options

In terms of voltage:

P5E 0903
Bios voltage - 1.3500v
Idle voltage - 1.3200v
Full voltage - 1.2880v

RF 0407
Bios voltage - 1.3375v
Idle voltage - 1.3200v
Full voltage - 1.3200v


You can see, the difference between the bios and the real one are minimal and the difference between idle and full are completely gone!!

PS:Results with LoadLine Calibration ON

With the RF BIOS does the max vcore go up from 1.7v?

The Asus P5E 0903 BIOS doesn't work well for my configuration. I can only run stock speeds and even that is not completely stable; even with a fresh load of Windows XP.

I'm switching over to the 0407 Rampage Formula BIOS tonight and see if that will solve the issues being experienced.

What did you use to check the voltages at idle and full load?

In bios it has option to 2.4v...

What did you use to check the voltages at idle and full load?

CPU-Z

LOL Gee, thanks. Thought you might have had something other than software to check the voltages.

Just simple software

If you want to give it a try, you can follow the guide here

THX, with the P5E 702 BIOS I only get 1.7v .

Use Deluxe BIOS is by far the best for P5E.

Anyone managed to get a Q9450 STABLE passing 435x8 on P5E ?

I managed 440x8, but needed a lot air, I guess it couldn't be normal. After I closed the case, it turns out unstable.

I use the Asus Utility for voltage checking. Fairly accurate in my instance. the only thing I use CPUz for is checking the the CPU and RAM overclocks to see how close they are to what is set in the BIOS.

I think CPU-Z can be more accurate and every one uses it...

Can you be more especific ? I dont know that the p5e deluxe fits on the p5e .

I'm using P5E Deluxe BIOS (0205) on P5E:


CPU:


Memory (using a single module for OC tests):


SPD:

436x8 with case closed is my stable now, going to buy a:

next week to see more (I hope) OC.

If i flash to the RF BIOS is there ANY side effects? Also is it then possible to re-flash to the proper P5E BIOS agian?

I heard that with the RF BIOS it stuffs up your temp sensor.

No side effects here and you can revert the process doing the exact same steps, but using the P5E bios

THX, i might do it after my LAN Just incase...

The real vantage of RF bios, in my opinion, its the difference between idle and full voltage...simply, doesn't exist!

Y is it good not to have vdroop?
