ASUS P5K Deluxe - Intel P35 Bearlake + E6600 B1 / Q6600 B3

[Nuckin_Futs]

there is actually a trick to revert the bios after you fleshed yours with v6xx onward. so in order to downgrade your p5k deluxe bios you have to:
1. download and install Asus Update v6.10.02
2. download the older BIOS version you want to flesh, unzip and save it to C:\
3. start Asus Update, go to Options and select 'BIOS downgradeable" and save
4. choose "update BIOS from file" and point to the BIOS file that you downloaded
5. after it finishes, reboot and MAKE SURE that you correctly clear the CMOS!! (might have to wait for 10 or more minutes)
(if you dont do this you'll have problems on POST)
I succesfully use it to revert to 311 "best" OC bios so far!
good luck!

I have done this and it works fien on this and my X38 Maximus. However What about if using the AfuDOS method w/ switches? I noticed the current ROMs are too big for the floppy even though manuals calls for min of 1024kb, and files shows as 2mb.

The question then, is how do I make a Sony Memory Stick Pro Duo bootable to run Afudos to back up old BIOS or flash back to stable final? Do I use the real FDD and direct to USB (my PSP w/ MS pro duo)?

Has anyone noticed that w/ the 0809 bios, the FSB in the bios does not match that in windows.

411 in bios = 413 in windows
418 in bios = 419 in windows

I have good stability (still doing testing w/ my new ram), but I was wondering if anyone has issues with this?

Found an interesting goof in the latest bios...

After manually changing the multiplier, saved OC profiles will no longer save the requested multiplier...i.e: You have the multi at 9, save the profile, dink around with some bios stuff and wish to go back to a saved profile...and the multiplier is at 7 for some reason after loading the saved profile.

No biggie, just move the multi back to where you want it and exit, but still would be nice if the saved profiles were correct. None of this happened until I manually changed the multi so who knows what's up with this.

Did someone already o'c-ed a Q6600(B3 stepping)using the 0809 bios??Can they show me their bios changes?

I only experienced this with the Qx if I pulled the power cord, if the PC was kept plugged in I didn't have this reboot issue... this is the reason I reverted back to 0703... Maybe all 45nm CPU's are victims here... I got a wolfie coming this week will pop it in and reflash to 0809...

809 is one of the worst bios releases have made for this motherboard.
i've went back to 311, and works super with E6600. tested with other CPUs, but the OC is unstable no mater how much voltage you pump in.
+the OC profiles will not work for diffrent bios versions.
on the assus forum i've found the fallowing topic related to manual OC / multiplier.
Cannot set overclock to manual
Can't change my cpu ratio!! using 0809
as usual asus does not show any interest in users problems and offers poor support for them.

The actual bios setting for the multiplier stays at 9 after rebooting. I noticed this only when loading saved settings from profile 1 or profile 2. It seems like the multiplier field is stuck on 7 on my board for saved profiles. But all is ok otherwise. I'll unplug it to make sure the multiplier stays at 9 with total power-off just in case.

Other than this, I gotta say this board and the 0809 bios is great, easy no-brainer OC's.

When I received my RMA board back from Asus two weeks ago, I thought I got a DOA board. It would not boot or POST. I tried three types of memory: Crucial Ballistix PC2-8500, OCZ Platinum Rev. 2.00 PC2-6400 and Kingston ValueRAM PC2-667. These are all 1GB sticks. I've tried it with just one stick, two sticks, and any combination. It would not boot nor POST. As a last resort, I decided to try my one Team Elite 512MB stick. And it booted! OMG...I almost called Asus again for another RMA. Once it booted fine, I went into the BIOS and changed VDIMM to 2.00V and Save it and all other memory would work flawlessly afterward but only if no clearing BIOS event occurs. Everytime this occurs, I have to put the 512MB back in, in order for the board to boot or POST again. The BIOS was an early one (don't remember which one, though). I flashed the board to 0809 and never had problem since (even clearing the BIOS). It seems like with the earlier BIOS, after clearing the BIOS, the VDIMM defaults to a lower voltage that higher performing memory can't work with. Whatever it is, I reflashed/downgraded back to 0311 just to tell out this theory and sure enough, after clearing the BIOS, it wouldn't boot again using the same memory that were having problem before. I put in the 512MB stick and boots right up with no problem. Reflashed back to 0809, no problem with any memory. I remember someone posting here last week sometime who was having a similar problem. Not sure if I read what he did to fix his problem. But different BIOS version seems to have a taste for certain vdimm voltage or something.

This is exactly what happen to me on a BETA BIOS on my X38 version. Flashing back for me iddnt help at all since MAXIMUS FORMULS BETA BIOS v0907 corrupted my BIOS chip and it did need to be RMA to get rid of the bug. going all the way back to 1st release did nothing and going up one by one to last known good BIOIS. So you are lucky to get out of it.

I think I just fried my first PCI-e slot (the blue one). I'm using the black one, but that only works on 4x. Is that any way to turn it into 16x?

My vga is capped under that 4x.

Some more semi-irrelevant minutia...

Same issue, but I found today that after a 'failed overclock' where the board resets to stock volts/speeds, the saved OC profile load-up gives the correct multiplier. Seems my dropped multiplier issue only occurs when loading into an existing OC.

Get the torches and pitchforks out!!!!

I just want to say that I've been following this thread for a while and after the 311 bios came out and I flashed to that there's just been no incentive to switch to any of the newer bios floating around. I really hope they fix the bugs in the 809 so I can flash before my e8400 shows up .

It's great if you have the right memory. From experience, BIOS 311 is picky about memory brand. Read about my discovery just a few posts back.

0812 is out.

will post build date once I flash

[jeeka]

0812 is out.

will post build date once I flash

Where'd ya find it? I wanna test. I have some time.

[jcniest5]

0812 is out.

Yeah, so where is it?

[JB87]

Yeah, so where is it?

Here.

[genec57]

The newest I see there is 0809

[Leeghoofd]

K Flashed 0812 :

For my Qx CPU : unable to set multiplier or unknown VID warning after a cold boot has been solved... TRFC values still there... for the rest no extra settings caught my eye... too bad I don't have the QX9770 anymore to test it with...

Did some quick tests with Everest for ram bandwith... more or less the same then 0705... memory bandwith is the same, latency however has dropped a bit...though Level 2 cache has got lesser scores... Can anyone confirm this ?

0705 :



0812 :



Will let the rig fold with my usual settings and hopefully tomorrow morning it will still be up

Question:
My B3 stepping Q6600 is set to 3200mhz on 1.385v,is this voltage good,or should i lower it a bit?

System is rock stable at these settings.

Is this Bios setting or readout in windows, you got laodline calibration enabled ?

Lower would always be better, drop down a few settings, but test each setting toroughly

[pappous_soulis]

I've manually set it this way in bios.

You mean load line calibration right? I can't remember seeing this option in the bios..i'll check it.

Edit: i checked it,there's no loadline calibration option.
PS Bios version 0202... :/

[Leeghoofd]

hehe time to update that bios then mate, I used to run on 0705 a long time no issues there... Try that one first as downgrading from 0812 isn't that easy...

and On the P5K it's not loadline calib it's called CPU voltage damper ( stil bugged by the Maximus bios set) my bad :p

Ok,i'll try 0705.But i'm gonna need some help (i'm a n00b lol )
I once tried upgrading the BIOS but while i was making backup of the original 0202 using the EZ Flash utility,for some reason it stopped and reported an error i can't recall right now.So my question is,do i really have to make a backup of the original?
Next thing i need to know,is how am i going to upgrade? Is there a guide which i can follow step by step or something?

(..by the way,CPU voltage damper should be enabled or disabled? )
