disable C1E and you should be all set

Thanks! Done and working

i need to get used to this board. my p5b-e i could do 405fsb with 1.425v. anytime i up the fsb and volts to what i used to do i bsod. also got ballistix 8500 i want to put to good use. need to play with this board for a bit i think

Hey guys, need some help, I'm close but not quite 100% stable

vcore 1.58
nb 1.55
fsb 1.4
vdimm 2.3

any suggestions?

1st suggestion: make your pics smaller, they mess up the forum's layout.
2nd suggestion: If you plan to keep that setup for longer than a couple of weeks, get your voltages down.

i have flash my p5k-e wifi bios to 0901 today, and noticed a huge vdrop (about 0.15v).
as many of you said, i am planning to downgrade the bios to the 0602 one. but i couldnt. tried with ez-flash, asus update, and Afudos. ez-flash didnt allow me to flash to 0602, because its older than the current 0901. asus update and afudos said the bios rom file is not compatible with my board (i am very sure i have the right rom file from the asus official website, for p5k-e/wifi), and doesnt let me flash...
so just wondering how you guys did the downgrade from 0901 to 0602....
thank you..

Read through this thread, the answer is in here and has been told a couple of times.

Received my P5K-E/WiFi-Ap a week ago, it's rev. 1.02G and came with 703 bios. Huge droop with 703, and had to change it with 602. Much better.
I'm going to try 603 also because I've read that 602 it's beta.
Testing now stability with my new E6750(L723B613) @ 3600Mhz 1.4v bios, 1.36v load.

Sorry for the big pics...

I'm not that worried about the voltage, I need 1.55 to run 8 x 500 but 1.58 for 8 x 525. I'm only running 1.6 PLL though....and am a bit hesitant to go much beyond that for 24/7. For some reason though going to 1.7v on the NB and 1.5v for FSB makes it more unstable... but I can get it load Vista 3/5 times at 8 x 550, the other times it fails to load the USB drivers at POST....

And I have a little old E6600 running 9 x 400 with 1.63v 24/7 folding and it's been running fine for over a year. ( it is water cooled though...)

I flashed from 0503 to 0603 no vdroop with this bios but , wireless can not be disabled in bios , actualy disabled but windows recognized it

I flashed from 602 to 603 about a week ago. I've got my FSB @ 408 with no issues now.

Problem is when I go any higher, I'll have random resets. This is better than 602 since I haven't had any BSODs at 408 or less.

I'd like to go higher since the CPU is only running 50c under full load and is completely prime stable. It seems the board is holding back the CPU.

For the curious folks, here are my voltages.
vCore: 1.4v
vDIMM: 2.2v
NB: 1.7v
SB: 1.2v

I know the NB is high, I have a ThermalRight heatsink on it and it stays under 38c. It was cooking at over 50c before the aftermarket heatsink, and cooling it down did increase stability.

I should be satisfied to have a quad running at 3.67 24/7, but I know this CPU is capable of more.

If I can't do better with this board then I'm gonna scrap it, once I figure out what to replace it with.

I'm fishing for suggestions on getting the FSB higher. Any ideas folks?

[AriciU]

Increase voltage. You can't expect ~3.8ghz with only 1.4v. Test it on some other board and watch the vdroop hell if you think the board is causing it

Don't scrap it, send it to ME!

would be good if somebody could comfirm this, cuz this was a problem of the 0806 bios

Yeah, you're probably right. I bumped it up to 4.25, we'll see if it stays stable at 409 then push for more if it does.

Do you think 1.7 is too much on the NB? I'm worried about the lifespan of my chipset =(

Also, when I set the FSB to 409 I found a neat bug in the 603 BOIS, check out the image.

Mine does the same thing on 603 BIOS, but I recall all other versions I've used acted the same way. I have the wireless disabled in BIOS, but it still shows up in windows. I have the "PnP OS" option set to yes, so it's probably handing off control of the wireless module to windows on purpose though, so I just disabled it in device manager and called it good.

Nice bug I think 1.7 is way too much for that FSB. I think you can set it at 1.55 no probs.

[jettasin00]

still just bsod on everything im trying. need to drop to the 603 bios from the 802.

[Zero939]

906 BIOS is up on the asus website, and there's enhanced memory compatibility


edit - no idea if the .1v bug remains

You test it and report back. Im scared of all the newer bios.

[Mordorr]

Just updat from 0206 to 0603....

So far, so gooD

nope, im sticking with bios 603 for life

[Mister2]

Seems you were right about that too, though I had to bump the CPU up to 1.4375 to get it stable again. Thanks AriciU.

Prime testing now, so far so good.

The extra CPU voltage only bumped load temps about 1c. It can probably take a good bit more. =)

Will be interested to see if the v droop bug still remains also.

P5K-E/WiFi-AP CPU Support looks like the latest bios 906 gives compatability to the new Wolfdale CPU's coming out i.e. E8200, E8400, E8500. Bios 806 gave QX9650 compatability just for your infomation.

Someone test out bios 906 lol you know you want to. . . .

[Zero939]

my friend says that 906 changes his CPU-Z ram reading from asymmetric to symmetric

[Blackoberst]

Flashed to 906, huge vdrop 1.425 bios/1.320v win idle/1.312v load with voltage damper enabled.
There are a few changes in the new 906 BIOS:
- added 400Mhz FSB strap to Northbridge
- changed Dram Timing to 1N/2N
- added timing info, something like 5-5-5-15-4-42-6-3-3 on the top of manual timing configuration
- voltage damper changed name to Load Line Calibration
- renamed CPU/NB voltage reference to CPU/NB GTL

Hey thanks for the heads up.

apart from the vdroop does the bios seem any better regards FSB. I know 602 is great just tempted to test latest.

You use old asus update to flash back the bios?

[Blackoberst]

I haven't tried max fsb. I only wanted to see if it has the same huge vdrop issue. I kept it like half an hour or so and flashed back to 603 using some old version of Asus Update 6xx. The link is somewhere in this thread.
I don't know how Asus could screw things up with the new bios versions regardind vdrop.

agreed. you would think the Vdroop would be sorted on latter bioses. I supose as its not a high end board they seem to think it wont matter.

I get no posts sometimes with 602 and have to boot with 1 stick of ram.
