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

[Krav]

well its confusing when it says on the board description page in the chipset features it works with ddr2 oh well

[fhpchris]

O.K. - here's one more for all my friends here:


X38 offers a maximum of stability at low voltage niveau. Still FSB 1.30, PLL 1.50 and set NB to 1.43 and RAM to 2.42 volts.

I never had a board running such hi RAM frequencies at strong timings and sub-timings with such low NB & RAM voltage settings.

BTW - LLC set to disabled, did the pencil mod. Vdroop = 0.000% !!!

556 4-4-4 isn't too bad :P

I do that on 680i with my "slow" VX2 at the same voltage

[Sparx]

How are you guys measuring Vdroop? In BIOS or with a Utility?
I want to do a before and after check so I know I have it right.
TIA

Using asus probe is the easiest way.

Thanks bigchrome

Yep - btw nice 3D run there......... - I'm just about to get 585 stable:



More than 10.6 GB/s read.............

[Sparx]

Just got the board up and running wondered if this 42C board temp is a concern.
I am at 27C only for the cpu but I only have it running 340x9.



I find the BIOS much more "robust" than the PW5 DH.

[Bigchrome]

I wouldn't worry too much about it... but it does seem strange.. I haven't seen over 30C yet.. Anyone know where exactly the sensor is located?

[Sparx]

Makes no sense. I am running (375x9) using 1.41 vcore and 2.1 Vdimm.
The cpu is at about 31F.
No sides on the case lot of air moving too, cool in the house.

I have no idea if it is stable as yet, have not had time to install any 3d Marks or Ortho yet.
Fried my new Corsiar usb stick, brand new, don't know WTF I did there was to use it for file transfers.

Also I am running 2t and 5/8 divider, just to BOOT at 3.375.

My P5W DH runs 3.6 1:1 and 1T and is solid.
Maybe this is not to be my new rig?

[darkgoro]

Thanks, and your bios settings would also be appreciated

I was gonna ask for the same think, me just fired up and testing, i got an e4500, and wont go up beyound 3ghz without serios voltage....i think...

[eyes.only]

Own a p5e vanilla and installed aisuite under windows xp.
When looking at the plain cpu temp it reads 24c, but the cores are around 38 (core temp or TAT).

Which values are correct??

[darkgoro]

I have an e4500, with stock voltage i can't have 3.00ghz, stable...is the board or the cpu? 3.40ghz only with 1.5v, way too high for me and still not stable...

having somewhat of the same problem:
can't get my p5e, q6600, 2x1024corsair stable even on default settings.
had same cpu and ram in another mobo and no problems whatsoever.

I'm completely getting out of my mind

Maybe faulty mobo?

[darkgoro]

Now somewhat stable 333x9 v 1.3840 idle, 1.3680- 1.3600 full load, with 1.40625bios, way too much volt drop, soon when i'll have the time gonna do the volt drop mod...
- idle


- full

sorry for the poor quality of the picts...

[ninogui]

(deleted) not the right place sorry

[fhpchris]

5-3-3 was faster than 4-4-4



And the Teamgroups!

[Sparx]

Got my MB temp issue solved. Reason it is high is that the power supply is mounted at the base of the case and the probe has to be near the bottom of the board. I put a fan aimed at the base of the board and got the temps down to 28c for MB.

I have found my RAM http://www.newegg.com/Product/Produc...82E16820231128 will not run 1000. I have it at 2.25 volts so it is not up to spec. It is D9 chips too!

What is good RAM?

hmm, think my p5e is a doa.

Tried to different sets of corsair 1024x2 pairs, but both get errors during memtest (allmost inmidiately). Also swapped my q6600 with my old e6400 with no luck.

Seems it's broken somehow.
Will send this baby back, not sure to get another one or get a p5k.
Any advice?

Bios used: 0107 and last one 0402.
Seemed to be getting worse by the hour.
Could do 3,5 prime95 with 4 cores without an error with some settings.
Now as discriped above I can't run memtest for 1 minute with any setting (default, overclocked).

[Brahmzy]

So my P5E is going to be here Wednesday. Is the 0402 BIOS and VDroop pencil mod the best/stable setup to date?

[djdare]

Hi everybody... I have one wierd problem when upgrading bios for P5E to 0401 or 0402.
Bios flashing procedure does everything "by the book" without any errors and boots to system spec and stops on press F1 or F2
(like always after flashing with new bios), to setup default settings or manualy setup settings. I can enter bios, customize my settings and save them.
When i reboot monitor stays black with fans running and no post from board.
All older bioses causes no problems at all (from 0303 and below). All settings are default non-OC.
Any ideas? Thank you for your help.

Asus P5E
Q6600 G0
2x1GB TeamGroup Xtreem PC2-6400 800MHz

Oh one more question, what is default vcore for Q6600 G0 (1,300v or 1,325v)

P.S.: I'l try booting with only one memory stick. (when i come home from work)

Well here's update to my problems. Booting with one memory stick didn't solve anything.
Have even tried with new memory stick and different brand.
I tried to go back to 0303 bios without luck. Error message is: The bios is older then...
So i tried with AFUDOS v2.10 utillity and floppy disc (Win98 boot disc). Here i get this error message: Main bios checksum error.
So it does not let me to flash it to older 0303 version.
But i got 0402 bios to work. It wont work with all settings at default. All i have to do is just set Overclocking to manual.
But it wont let mi to overclock my memory higher then 428MHz.
On P5B-Deluxe i could go as high as 560MHz with same memory.
Is there any other way to flash bios back to 0303?
Thank you!

What did you exactly do?
I'm sending mine back today, so wanna try your method.
So I select default settings and what do I change more?

I got my board with 0203 bios. Later was updated to 0303 bios. With this bios everything worked ok.
Next update was 0401 bios. After flashing, first boot was ok, but when i restarted computer it wont boot anymore. Good thing with that bios was that i could flash back to 0303.
At last i updated to 0402. Same as 0401, first boot ok after restart not booting anymore. Well problem now is i can't flash back to 0303 or 0203, it just wont let me.
So i tried with AFUDOS (i used an old version v2.10 and 2.07. Latest v2.29 wont let me flash, says: Your bios is older than...)
With older version it starts ok (verifying files), but before flashing i get this error: Main bios checksum error.
To make my board work after flashing with 0402 bios i have to manualy (F1) change settings in bios and save.
With option F2 (default settings) after rebooting computer it wont boot anymore.
The only thing that i have to change in bios to make board work is to set in Ai Tweaker -> Ai Overclock Tuner from Auto to Manual.
Then i can boot and reebot without any problems. Bad thing is that i can overclock my ram only to 428MHz.
I'm at work now, when i get home i'll try more.

Hmm, problems seem related:
When I get sometimes a boot block (or something error) and I choose f2 (boot with default settings and continue) and run memtest86, I get no errors whatsoever. But when I reboot again (hangs most of the times) the problem with the errors is back. Will try your trick when I get home from work.

You can't flash back to older versions in Windows - just save the BIOS files on a CDROM and flash it with the EZFLASH option in BIOS.

Tried to flash back from 0402 to 0401 and 0107.

Did it with afudos (2.29 I think) and EZFLASH.

All complained about bios being older then the one installed.
