***OFFICIAL Asus P5K-E/WiFi Thread

I don't think you can set it at 16x anywhere. You can check the speed it's running on using CPU-Z, under the Mainboard section.

[Crazykooter]

Depending on your video card determains where to set pci-e speed. I have a 3870 and I need to run it at 110 + to get the best overclocks. Its very common. Also if you exceed 120 your gonna drop your os flat on its face. So keep it at 115 max imo.

Heres is a link to my highest mhz run in 3dmark06-4230 and I think I could get this thing stable at this mhz but I dont want to run 1.6v all the time.

Here are some screens I took of my bios cept the vcore is now lower.

I tryed flashing back up to 0901, but have the same results. Low FPS in game and 3dmark. I checked PCIE setting between 100 -120 without change and tried your settings Crazykooter.

I just checked CPU-Z and found in the mainboard tab that the link width is x1and max supported is x16. I am going to set bios to stock and check to see if these settings change.

Thanks for the help so far. I will mention that the pencil mod has me overvolting by 0.03 in bios 0603 and undervolting by 0.06 in 0901 bios. So, I like the 0603 bios because I can set my Vcore to 1.45 and reach 3.6 stable with a PCprobe reading of 1.47, no vdroop under load.

[spider_d]

yep, there it is. With bios set to stock, CPU-Z reports link width as x16. So, something past 355 FSB is lowering the link width to x1 and killing my GPU performance. Any suggestions?

I had the same problem on my p5b, anything above 375 fsb resulted in 1x PCIE. i got around it be upping the sb vcore slightly.

Hi.

Nice to see people excange new experiences...

Im on vacations, so no acess to my rig....

Im thinking to try 0603.....but before new update, should i do a default reading in the Bios?

And them update?

cheers,

Yip...you should never update bios when overclocked...allways set it to default first.

[spider_d]

I notice now that I am getting x1 link width with 3200MHz too. That's 355 FSB. I will try the SB voltage up. I have NB at 1.55, and both NB/SB are under thermaltake extreme spirit II with 120mm fans blowing at them, so temps should be fine. I'll be out for a while but will report back tonight

[jgxworker]

Just installed my P5K-E. Its revision 1.01G and came with bios 0603. Testing my old-school conroe E6600 @3.6GHz stable right now. More results will come next week.

[sam95ta]

I thought bios 603 was for P5k Deluxe.No where do I see 603 for P5K E.

dont know why, but I couldnt find it also available, although my P5K-E was shipped with the 0603
If you cant find BIOSes here are some:

I bumped up the SB to 1.2volts. Thats the max. No change. Still x1 link width when overclocking. NB voltage up to 1.55 with no change. Some setting is lowering the linnk width from x16 to x1 whenever I overclock.

[spider_d]

I think that I have found the answer. Here it is;

7. If you are experiencing a jerky desktop, slow graphics performance, low framerates etc or any other kind of graphical corruption (this is mainly for Asus boards), load up CPU-Z and in the section that tells you about your motherboard, look at the bottom where it says something like PCI-E Link Width, it may have changed itself to 1x instead of 16x (this happened to me yesterday), so to fix it, go into the bios and cheange the PCI-E frequency from AUTO to 110 (you can try any value up to 110), save and exit, boot into windows and check with CPU-Z that the PCI-E Link Width is now set to 16x. If it is still at 1x, repeat what you just did, but up the PCI-E frequency another notch, check with CPU-Z and if it is back to 16x, go back to the bios and change it back to auto, and hopefully, it should be fine

In the troubleshooting section. I am going to try it now

[jettasin00]

well i ordered my P5K-E the other day. waiting for it to arrive with my ballistix 8500. cant wait to push this around

[barzi]

I want to buy a e8400(45nm cpu) but i now have bios 0603. 0703 was already installed but it had a huge vdrop.
Now everything is allright, but i want to sell my e6600 tomorrow. So from which bios can i run e8400? So i can update to that bios, otherwise i can't start my computer if i got the e8400.

So since which bios is 45nm cpu's (specially e8400) supported?

If i look at the supported CPU list I see that the Core 2 Extreme QX9650 is supported since 0903. That's a 45nm cpu, right? But is this for ALL the 45nm cpu's?
And if this is right, the box of my p5k-e is wrong. They say: 45nm support. But i had bios 0703..

[spider_d]

This is a good question from barzi. Which bios supports 45nm chips?

[Crazykooter]

I believe its the 0901 which is the worst bios yet.

Has anyone here reseated there northbridge heatsink to see if better thermal compound is making a diff ?

[barzi]

0603 is a very decent bios, but if i want to e8400 i have to update to 0901, right?

That's too bad . What happens if you put a e8400 in the p5k-e with bios 0603? Is it going to start-up but you can't use the bios functions for the cpu (overclock and stuff)? Or will it just shutdown after a few seconds(something like: no cpu)?

[MalaMen]

i think that you can enter in bios even with the 8400... so in this case the worst can happen is that you will have to update it with a pen drive

[barzi]

Hmm ok, that's nice.
But If i wanted to "update" my bios from 0703 to 0603 EZflas said "Not valid boot block", what does that mean? Or is this because i actually wanted to downdate?
I updated it later with the ASUSupdate tool in windows.

[jgxworker]

Still. My mobo said 45NM supporting on the box and came with bios 0603. This means that it only supports the QX9650 with 0603? Its kinda strange though, that it will only support that one and the box says 45NM ready. I don't think that the box is wrong. That would be really stupid. By the way barzi. Is your motherbord a 1.01G or a 1.02G Revision? Because mine 1.01G came with 0603 and yours with 0703.

[mft4]

does anyone know the difference between board revisions?, ie 1.00g 1.01g 1.02g

mine is 1.00g

[mft4]

according to asus the Core 2 Extreme QX9650 is supported from bios 0806

here

[Rocket]

I finally pushed my Q6600 and P5K-E Wifi to 4ghz
Takes alot of v-core to get there though.
I have it set at a sweet spot of 3465mhz (1.27 v-core) prime stable for 24/7 use

[Mordorr]

does anyone know the difference between board revisions?, ie 1.00g 1.01g 1.02g

mine is 1.00g

I have also the same question, and the same Board.....

I did look to both, and didn`t see nothing diferent....

P.S. Remenber now....number of conectors in the power cable??

[barzi]

Where can you see which rev you have? Cpu-z gives 1.xx..
