Modded ASUS P5Q/Pro/Deluxe/Premium BIOS

Question regarding my setup - its as the sig says but with the following settings:

CPU vCore: 1.41875
GTL Ref 0/1: 0.670
NB: 1.14
FSB Term: 1.14
PLL: Auto
DDR: 2.0

Now i'm using a 2x2gb set of G.Skill PC6400 PQ's, these have been through memtest at 5-5-5-15 @ 2.0v, 900Mhz + and they've been stable (with the CPU at stock)

However, i think i may have hit a wall of some sort - 445x9 works, but 421x9.5 is more stable. And i can't drop the voltage any lower, or else Vista will BSOD with a MACHINE_CHECK_EXCEPTION / Stop 0x0000009C Error.

my FSB hovers between 421.0 and 421.1Mhz so i dont think the PLL needs to be increased, but seemingly, increased NB/FSB Term just make it unstable. Should i be decreasing the GTL Ref when decreasing the vCore as well?

I would try decreasing the GTL Ref, yes :up:

CPU vCore: 1.41875
GTL Ref 0/1: AUTO
NB: 1.14 --> try 1.2
FSB Term: 1.14 --> Try 1.2
PLL: Auto--> Try 1.56
DDR: 2.0 --> overvolts try 1.92

Leave all the GTL's AUTO

I did as suggested and now running ORTHOS at 1.40625v, GTL set to Auto....4mins in and its not BSOD'ed yet :p

Just thinking though, the first BIOS this board had was 0803, and from that point on, i've left the GTL ref at 0.670, so i'm guessing that now at 1702, somethings changed that my GTL ref doesnt need to be that high anymore?

Leeghoofd - wouldn't i want to LOWER vFSB if i'm trying to DECREASE core voltage?

With the auto settings for the GTL's if you up or lower the FSB termination voltage the CPU and NB GTL's values are altered as they are linked (no idea how to explain this in proper english) With the GB mobo you can see this clearly with the different reference values as it shows them...I just want you to be stable first and then you can slightly go lower mate... but I only needed to tweak the GTL's on the DLx from 450FSB with the quad, with the wolfdale I needed manual tweaking from 533FSB or such... be lucky you don't own this DDR3 P45 version, they are even more sensitive ( even with a duallie ) think the strain on the P45 chipset is too much for it too handle

Also I couldn't even post with FSB Term 1.14 on my rig I needed 1.18 at least to get it going (talking 400-450FSB quad and 500-550FSB duallie), Nb voltage lowest I could go with 4gb ram was 1.18-1.2...and all depended too on how much I tweaked the ram... for 24/7 I prefered to set it a bit looser...

I have said this before the voltages I post worked for me and can be lowered for sure... take them as a guideline but your final results can be totally different from what I posted... Asus did a nice job in the bios with these GTL values...

the new bios for the E let me finaly hit 4ghz! yay. i need to tweak it some still as the volts are kinda high all around.

@ oMek,:up: Nice job!

Larry

nice one oMek ! :D

put +1mhz in so you get rid of 3xxx Mhz club :up:

That with mBIOS or vanilla? (I'm assuming mBIOS as you posted in this thread, but just checking :p: )

Sorry for stupid question, what is vanilla?

the original version = vanilla

why it's called vanilla?

Vanilla is another way of saying plain. boring. ordinary.

thanks people ^^

and yea thats with mBIOS, i dont dare use stock ones now. infact your mBIOS are the only reason i kept this board. hated it before i found em :up:

Just glad I can pep these boards up for people :up:

Maybe a silly question, but does P5Q mBIOS use P5Q Premium memory table here?

Indeed it does :up:

Yeah, another mBIOS where I dont get the boot image either lol.
Just wondering ket...wouldnt it be easier and less frustrating not to edit the boot image to get rid of variability? jsut saying...
anyway, merry christmas!

Just a boot logo. Not exactly that important and its easy enough to change the logo anyway just by using the asus mylogo app, hence why I'm not really bothered by the fact some people can't see the logo while others can.

This post is specifically to help those out there who have flashed their (AMI) BIOS (any manufacturer, vanilla or modified BIOS) and are finding themselves unable to revert back to an older BIOS or update their BIOS.

How this anomaly comes about I'm not sure, but one manufacturer especially are notorious for this anomaly occurring with, ASUS. To get yourself out of this bind follow these simple steps;

1. Download the AFUDOS attachment (2.11, AFAIK this process will NOT work with newer versions)
2. Make a bootable floppy \ CD \ USB \ whatever with the BIOS you want to flash to on
3. Place the downloaded AFUDOS utility on to your chosen boot media
4. Restart
5. With (for the intentions of this example) your bootable floppy loaded and ready to go, type in the following then hit enter;

AFUDOS.EXE /iXXXXXX.ROM /PBNC /N
**XXXXXX denotes ROM filename**

Thats it! The utility will now perform a comprehensive set of checks, erasing and writing procedures. Just sit back and watch it do its thing and restart your PC when prompted.

note for this comm. line AFUDOS.EXE /iXXXXXX.ROM /PBNC /N
this will kill the ethernet chip in the mobo. which have atheros lan on it
like P5Q it will damage the mac add. of it

As far as I am aware, no it will not. Tested it myself.

I am sure of it
tested it on P5K(P35) and on P5Q(P45)
THIS two mobo. have the sam lan chip and with this boot plock no check comm. the mac add. of it will damage

this for the p5k mobo.
the link for the p5q mobo. will come soon
net prob. here sorry

As I said, I have tested that method myself on my P5Q Pro, The Atheros chip is fine. Windows detects and installs the driver for it.
