Modded ASUS P5Q/Pro/Deluxe/Premium BIOS

[Dee]

We should ALL be thankful... we have PCs... or parts of them LOL.
Yeah, no matter how bad you think you are, there's always someone that's doing worse.

Nice. I like a man with a sense of reality. Good on you, Axy.

hey ket thanks for the wicked mBIOS (iam new here and new to overclocking but since i tried ur mBIOS i have some nice stable overclocks going)

i have my E8400 C0 @ 4GHz Prime Stable now 1.4v in win, the best i could do before was 3.825GHz @ 1.3

umm when i went to default yesterday the mBIOS went to 266 FSB, the only way to get it too 333 was to enable Ai Overclock. i dont know if thats a known bug or not

@dee, could you please tell me what your voltage is on your cell shocks to run 1300? thanks

[Poohead]

901m bricked my p5q pro.. tried everything.. cmos.. holding power down.. no battery.. is there a more stable bios?? or whats the one you recommend for a p5q pro.. and which program to flash it? i got another one..

Just registered to say 901m bricked my board as well. I've run all the other P5Q Pro bioses posted without issue until I tried this one. Thankfully I have a second P5Q Pro motherboard that I used to reprogram the bios chip.

I can't tell you exactly because I set it to 2.25v for benching and didn't try higher or lower. I changed it back to 1200MHz again now. I'm too lazy to update my sig. 1200MHz is rock solid with 2.02v set in BIOS.

EDIT: Actually, I think I'm wrong. It was set to 2.18v in BIOS. That would turn out to be around 2.25v "real" if this board over-volts, which I read somewhere that it does.

I have a quite big Problem with the P5Q Deluxe. When i boot my PC nothing happens. If i then reboot it between 10-20 times it Powers up. The harddrive, vga, dvdrom and anything boots up but the "beep" never happens and the screen dont turn on. There isent any error beeps or anything. When the PC then finally is up it is working rock stable with no problems in all tests/games or programs and have atm been online for about 2 days. I dont wanna shut it down when there is problems with powering up. I have tryed new bioses, ram in other slots, checked settings, voltages and so on and nothing helps. I know i arent the only one with this issue but what should i do ? All of my parts are new bought parts here from a week ago. If you need anyother information please let me know.

Kind Regards MakkeMan

Sounds like broken memory stick, i got experince when ol' good times on duron 1,2Ghz and 98Win my 512mb stick was giving me headcache, untill i changed it

But the memory is working fine when it has posted up. No errors/instability and scores are great. I have tryed the modded 1306 with no luck either :S

[Ket]

Hopefully the new mBIOSes will be up soon guys. Ran into unexpected issues with my EPROM programmer, it recognises, reads, and erases the BIOS chips, but for some reason it won't re-program them :\ still working on that.

[hema]

may be the bios chip damage
you can try another IC

Yup so did my stick back on old days, When i get to windows it worked 100%

I have 4 ROM chips, the programmer can't write to ay of them. I'm just gona have to mess around with it more :\

Hi forum,
I did OC the Asus P5B deluxe, Abit QuadGT and Abit IP35 pro. But when I first looked at P5Q pro BIOS, it overwhelmed me a bit. So I did spend 2 days to read careful the whole 38 pages of this threat and several others from TPU OCN... I got some idea though but still don't know where should I start (Voltage?...) and what is the safe limit? I have P5Q pro with Ket's m1037 BIOS, Q9550, 2x2GB G skill 1000. Questions: 1. What is the expectation of this combination (4.0, 4.1...)? 2. What are the good start points for voltage? and the limit of each that I should know? 3. I can boot to windows with FSB Strap 400. Should I stick with this? What is the benefit of strap 400 vs 333 vs 266... I just wonder why Ket like to set the Strap to 400 while back in p965 era people like 333 more than 400? 4.Should I mess up with SKEW and GTL pref or leave it auto?
Thanks guy

Hi.

There is no "safe" limit for CPU voltage. It depends on several factors. If you plan to use the processor for a long time then you probably wouldn't want to push a ton of voltage through it. Also, opinions vary on how much voltage is safe. Personally, I don't like to go above 1.4v on 45nm CPU's. Intel would probably suggest something like 1.36v as an absolute max for CPU. Whatever you set the voltage to in your BIOS, it will be lower than stated. Check in CPU-Z for a more accurate reading. Example: for me, 1.3v set in BIOS gives me approx 1.26v. For my maximum OC, I use 1.4v, but the BIOS needs to be set at 1.425v.

Concerning the other voltages, a good place to start is just one or two notches above standard, for example, 1.10v is the standard for North bridge voltage on 45nm CPU's, but considering this board over-volts quite a bit when supposedly on Auto, take it to 1.12v or 1.14v. When you do this, the board sets it to somewhere closer to where it really should be. It's also surprising how far the P5Q series will go on small voltage bumps.

try to keep CPU PLL Voltage below 1.6v. 1.54v should probably be enough.

As I said, keep voltages as close to stock as you can, see how far you can take the CPU overclock, then raise gradually as and when needed.

Use whatever strap works and gets you closest to your optimum RAM speed.

Don't mess with skews and GTL's until later. These are more for fine-tuning and might not need to be tweaked yet.

I have Load-Line Calibration enabled. Without it, I get HUGE vdroop.

I like Speedstep and C1E. Running without these is merely a waste of electricity.

You may need to adjust CPU Margin Enhancement. This has been known to cause problems on quad-core CPU's, although I think they might have fixed the problem in more recent BIOS.

[ngocrebel]

OK, while waiting for your help I start with this:
470x8.5 (4GHz)
PCIE=102
FSB Strap=400
DDR2=942
RAM timing 5 5 5 15 and the rest are auto
DRAM Static read control: disable
DRAM read training: Disable
MEM OC charger: Enable
AI clock Twister: moderate
AI transaction : Auto
Vcore=1.34375
CPU GTL : auto
CPU PLL : auto
FSB ter volt : 1.3
DRAM volt : 2.1
NB volt : 1.3
SB volt : 1.2
PCIE SATA volt : auto
LLC enable
CPU Spread spectrum : Disable
PCIE spectrum : disable
NB & CPU Clock skew : auto
CME : compatible

Prime95 : 5 min and runing
Real temp: Max: 67
People say that FSB should not higher 1.35 for 45nm, Is that right?
How about NB ? what if I want FSB close to 500?
What should I do now?
Thanks guys

[Dee]

Looks OK so far, although you may be able to keep SB voltage lower than 1.2v. Mine is still on 1.10, I think.

Yes, you may need to raise NB voltage for higher FSB's. You can go pretty high on this if necessary. I have never needed to take mine above 1.36v for 540+ FSB. Probably could have been lower. I didn't test it lower, just took it there for benchmarks and seeing if I had a FSB wall.

FSB Termination may be a little higher than needed.

Does your RAM really need 2.1v?

[ngocrebel]

Hi Ket,
Thanks for your mBIOSes. I read this thread while waiting for my P5Q pro and Q9550. The first thing when I got the board was flash yours m1037 and I'm very please to do that. Beside of thank you I want to let you know that the m1037/P5Q pro work on strap 400 like charm. May be it just doesn't like your E4400 though.
In the other hand, read through the thread I see people mention about donate in order to buy you some time for the work. I'm not rich but I'm happy to shoot you $10 for the awsome work but I don't know how. I also see people said that they poor and cannot donate. IMO, $5-$10 for the unvaluable mBIOS is posiple. Why we ready to pay for ASUS crap BIOS but not these awsome mBIOSes. I think, at least 1000 people using your mBIOSes now. If they do, you have $5000-$10000, how's that!

[ngocrebel]

Thanks Dee,
My RAM should be OK at 2.0. Let try that. So I should lower FSB Ter volt, SB but up the NB a little bit, right?

[carepolice]

I belive that ket doesnt have rights to make money whit this great project

[ngocrebel]

OK, after play around with voltage setting, I still cannot make it stable @4.0. It's surprise me because I can get in windows @4.0 easy but cannot make it stable? Can someone help me this? Thanks

If i am right you have Q9550? If its C1 you should really forget 4Ghz at start already! On E0 it is possible... easily on some situations. But on C1 and high vid it is pretty hard. Try get 3.6-3.8Ghz stable that would be best way to go.

[ngocrebel]

Thanks carepolice
Yeah, you're right. It's a C1. Kind of PITA cause I can even boot to window @4.1 with 1.34 Vcore. And IDK why but when I up the Vcore to 1.35 it will not get into win. I don't want to try higher 1.35 though. Anything but below 1.35 it boot very well. Otherwise do you know what is safe VTT and NB volt for this chip. How about GTL CPU and Skews. People said it may help stable???

[carepolice]

Oh there is many view about safe volt values, even on these forums

On intels papers max Cpu voltage aka vcore is at 1.36! as 45nm technic you dont need high voltages for 20-35% overclocks!
example volts that i use for 3.6Ghz on my Q9550 (C1) and P5Q-E mb
in bios i have

Cpu voltage: 1.27 whit LLC (Loadline calibration) enabled CPU-Z shows 1.25 LOAD! Just test what voltage your chip needs for your clock, as you get to windows 4.1Ghz and 1.34 i belive that you can do lot of lower volts that 3.6 wich i use!
vPLL: 1.54
NB VOLT: 1.18
VTT: 1.14
vDIMM 1.8 (my memories stock voltage)
vSB: 1.1
vSATA 1.5

GTL's i have left auto becouse in my opinion those are only needed on high-end overclocks! And those are pretty hard to tweak none can say what is the "sweetspot" just for your gear!

[Dee]

Thanks Dee,
My RAM should be OK at 2.0. Let try that. So I should lower FSB Ter volt, SB but up the NB a little bit, right?

Just keep tweaking and experimenting. You'll find the sweet spot. I can only speak for myself as regards SB voltage, and as I said, mine doesn't need an increase at all.

[Ket]

Sorry for the delay with the next installment of mBIOSes guys I still don't have a main system running as the EPROM programmer I have I can't fully figure all the jumper settings out to at least revive my AW9D-Max.
