***OFFICIAL Asus P5K-E/WiFi Thread

[g1raffe]

The fix for that issue usually is just increasing the PCIe frequency to 105 or 110, or in the case of some other MBs(eg. Gigabyte), increase the PCIe slot voltage. Not sure what else you can do..

Looks like I will be needing to upgrade my BIOS for proper Penryn support, even though I don't want to.. a 0.1V vdrop means the max vcore I can get is 1.6V right? I like 1.7V for benching.

[Zeus]

confirming 0.1v vdroop on 0906 bios with pencil mod that creates 0.03v overvolt from bios setting to windows reading. No load droop. Stability and temperatures seem similar to 0603.

I am still encountering link width issues were overclocking results in lowered link width to x1 from x16, causing severe GPU performance issues. I can set PCIE frequency to 110 and correct, but the issue sometimes returns. I have tried settings up to 120 with similar results. Anyone find a permenant solution?

One more time:

Vdrop-- setting 1.5V in bios but getting 1.4V in windows( just an example)
Vdroop-- 1.4V idle in windows, but voltage going down under (heavy) load, like ~1.35V.

Please, try to use the right term to avoid misunderstandings.

I'd really like to know if bios 0906 has Vdrop, i'm getting a wolfdale and i would love to have 1.7V if possible.

Yes it has vdrop. ~0.1v

Flash it .... and for my surprise look at the mem divisor :



3:4 divisor like in the X38 boards

Dear Xtremes:

Today, the worse Overclocker Nightmare did hapen

- Just arrive at home, and the Monitor was black!

Reboot.....nothing....

I even went to buy a cheap memory Kingston, to reboot...

I did get inside the Bios, and even on XP.....but every time i had to reboot, no image!

Strangly, every time i remove the batery, and clear CMOS, and didn`t conect the Monitor Cable, i could enter in Bios......

When i did try, to reboot.....back to black image....

The sound was long -short -short-short.

Finaly, after 100000***** reboots, i did buy a cheap Video card, and Magic happen

I could enter, reboot and change Bios.......


Questions:

If my Asus 1950PRO is defective, why could i enter in Bios, with cheap memories, but not reboot???

I even could go to XP SO, like nothig did happen

I hate this Asus, since i could change GPU & Memory speeds, thanks their protection....now the result is a crazy dead grafica card.......

Could it be some modification, in their firmware?

No Juice from Enermax 475?


A month ago, i did have to go to the store, with my PK5-E, and they put a cheap memory, enter Bios, change Vdram, and them i put my Muskin...

Then they try my Asus VGA, and all went ok.

Now, i must gess, that this Asus VGA, was always defective........

Sorry the testement....

You flashed to what?

If you flashed to 0906, please tell me how bad the vdrop is.

[barzi]

Please tell us about the vdrop! .
I have 0603 now, but i don't have a CPU at this moment. I'm waiting for the e8400. But when i get that CPU, can i update my bios to 0906? Because i think e8400 is not supported in 0603.. How can i upgrade then?

If i look at this list:

http://event.asus.com/mb/45nm/nl/

I see that the P5K-e Wifi has native support for 45nm CPU's. Does this mean we can use the e8400 with bios 0603?
But here, they say from bios 0906:

Don't worry, it'll boot.

It will just moan on every bootup about the CPU microcode update.

[barzi]

So i can update the bios if i want to with the e8400 to 0906?
And will overclock work right with bios 0603?(then i don't want to update)

[jVIDIA]

I flashed with the new oficial 0906 !

Noticed Changes :

- some bios options renamed
- some bios options location changed
- one or two new options
- 3:4 memory divisor !!!!

Oficial changes :

- support for the new 45nm CPU's ( E8xxx )
- enhanced memory compatibility


As to voltage drops :

vdrop (bios->windows) = 0.1v like the latest bios since 08xx, so to get 1,4vCore in windows I have 1,5vCore in bios

vdoop (iddle->full) = don't really know because I have the pencil vdroop mod, and it's almost 0


As to OC, my system is stable as it was with the 0602 !

[g1raffe]

Is there much difference between BIOS 0503 and 0603? I'm running 0503 but aren't sure if I will get any benefits of upgrading?

Running E6850 now, will be running an E8400 soon.

I think I will run one of those when I first get my E8400, so I can run some tests with close to 1.7V, then I will upgrade to the latest BIOS.

[Mordorr]

It was water, from the Apogee GT.....

Everthing is ok, except 1050PRO...

I hope, later clean it and recover the Asus 1950PRO

Thank you, God of Overclockers, to spare my PK5-E...

Green stuff all over it........

[jVIDIA]

g1raffe, if you are going to put an 45nm CPU I advise you to flash 0906 bios. If you are going to use an 65nm CPU then use the 0602

[king]

I'm flashed my P5K Premium 0404 to 0504 bios and i lost stability..

Q6600 G0 VID 1.300 V

0404

425x8 1.41 V 24H full load ok


0504

425x8 1.43 V 24H Full load ok..

and always 0.01 V drop with voltage damper enabled

Wrong thread buddy, this is about the P5K-E not the P5K Premimium, there's also a thread about the Premimium in this section.

[spider_d]

I am still having trouble with the PCIE link width setting itself to x1 when clocking past 355 FSB (3200MHz). I can change the PCIE frequency from Auto to anythin between 100-120 without success, and beyond 120 I can not boot into windows because of an 'incorrect boot device, please select proper boot device and reset' message. I can not get around that message either.

So, for now, I am stuck at 3.2 with great graphics and a water cooled system. Also, I have found that this board can not boot 1T with Corsair XMS2 PC2-6400C4 and PRO 1GB modules. Timing 4-4-4-12-2T boots fine at 856MHz, but 1T won't boot even underclocking the memory.

I can not wait toget the E8400 in there and see what happens.

Any advice is welcomed.

PS. I have tried different NB/SB/PLL voltages without any success in link width. Just thought that I should mention it.

0602:

BIOS: 1.4325
Idle: 1.416
Load: 1.400

0906:

BIOS: 1.5250
Idle: 1.416
Load: 1.400

Idle->Load was the same in 0906 with or without Load-Line Calibration Enabled.

Having 400 MHz FSB Strap is nice.. 1066 with L3 Transaction booster was a nice touch.

[TigerFury]

Would someone mind uploading bios 0603 again? Previous link doesn't work for me

Dang, that is one nasty drop!

[g1raffe]

Flashed to 0906 for official Penryn support.

0503:

BIOS: 1.7V
Windows: ~1.66V

0906:

BIOS: 1.7V
Windows: 1.57V

I might flash to 0603, can someone confirm that this does run Penryn ok? Even if it gives you a uCode error at startup that doesnt worry me.

[AriciU]

Why did Asus decide to "evolve" from good to bad with their bios'es? I cannot understand why mess with something that works.

[cnumartyr]

Dang, that is one nasty drop!

Yea... I don't like the drop...

If they would open up the options to about 1.9vCore it wouldn't be so bad for me. At the same time.. if they would just tighten that drop up I'd love them.


Why can't we have the drop from 0602 with the options and dividers in 0906!

We need a bios genius in here who could just implement the Vcore of bios 0503 into 0906.

Tictac, Tony? Where are you guys?

[spider_d]

I am in discussion with Asus about the Vdrop issue. And by in discussion I mean that I have contacted their tech support and expect to hear back from them by 2009 with a solution. Something like, "we do not advise changing the Vcore setting in the bios, thank you for contacting us.'

[godsfist]

1.5 shows as 1.38 in windows for me
