Asus P5B (vanilla) Overview

Nice! What BIOS? :)

Why are the results so mixed in terms of FSB overclocking?

I think you never clicked http://www.xtremesystems.org/forums/...ad.php?t=93183 :p:

I`ve not seen that thread before, that unit is hella clean! But sadly not as much to do with FSB. Unseens results above can be done on water, or air.

well the url I gave is from the same guy :cool:

Same guy, but not same rig ;)


Sorry, cant help with the monitor signal question

In my experience, no board give video signal when there is no cpu or memory. They are needed to post.

So how is this board with E6600? Building two P5B-rigs tomorrow, one for my friend with E6400 and Corsair 6400C5, and E6600 + Geil Ultra PC6400C4 for myself. Looking forward to have some fun with those two bastards :)

Will be running Big Typhoon @ E6400 and possibly water on my e6600.

509 is out

P5B Release BIOS version 0509
1. Support DDR2 double side x16 module
2. Enable support for CPU ratio adjustment on Kentsfield B0 stepping CPU
3. Enable conroe/kentsfield ratio overclocking higher above default value
4. Fix CPU Fan profile mode not correct after system shotdown
5. Revise temperature reading algorithm
6. Update MRC code
7. Enhance memory compatibility for DDR533 and DDR667 modules.
8. Revise S3 fuction not stable when CPU FSB over 300MHz.
9. Add dram frequency help string

Unseen what mobo and ram?

Where do I find that BIOS?

Asus Update doesn't work for me.

Btw anyone tested the last bios ? This point look interesting:

3. Enable conroe/kentsfield ratio overclocking higher above default value

I remember reading Asus was working on a way to unlock C2D ratio.. Could be interesting.

I just tried. I could only get it to lower the multi. Anyone else wanna try?

Does someone here has problems w/P5B+DDR2 on Elpida chips like me ?
I got A-Data DDR2-800 Elpida
ASUS P5B:
1.8V 800MHz 5-5-5-15 = no go <-SPEC
2.0V 800MHz 5-5-5-15 = no go
2.0V 800MHz 4-4-4-12 = prime stable
DS3:
1.8V 800MHz 5-5-5-15 = prime stable
2.0V 800MHz 5-5-5-15 = prime stable
2.0V 800MHz 4-4-4-12 = prime stable

I thought that the problem was in BIOS, but NO ...

anyone know if there will be a bios release for this board that will allow higher than 2.1v on the ram?

there is no such BIOS ... yet :(

Hello!

I am using SymcMax Express DDR2 667. Reading from cpu-z, the chips are Elpida.

Here are some of the stable timing and voltage:
1.9V 667MHz 3-4-3-10
1.9V 800MHz 4-4-4-11
2.1V 920MHz 4-4-4-11

Man this board is great! I just got it and week 26 6400. Just installed windows last night and up and running with my new apogee block and dual heatercore. just reading the threads on the p5b vanilla and took some notes. TY very helpful guys. 400 fsb no problem. Actually it's strange...when I set all the values in bios and hit f10. normally you would have a quick screen flash and post beep and os loads. in this case the board would actually shut down completely and fans stop ..etc. then the board will restart itself??? I thought my oc was bad but it boots right up into windows and I checked w cpuz and sure enough I have overclocked 3.2ghz 1st try. I just ran a 1M spi. looks good so far. I'm gonna keep going. Anyone have the same shutdown after F10 issue?

Everythink is OK ... Whenever you change sth in BIOS and apply (w/F10 or w/Exit&Change settings) - before restarting, PC completely turns off ...

BTW - did 500MHz FSB w/E6400 under water http://images.people.overclockers.ru/88915.png 501MHz - system doesn`t boot
Waiting for ClockGen ...

Nice man! what is actual voltage in bios? I am at 1.52v

Vcore = 1.575V
V(FSB)=1.4V

that 1.575V in bios only gives you 1.49 in windows under load, is that right.

if so its an amazing chip you got there m8.

Yes the board is strange where it restarts the power twice when you change an important bios setting.
509 does nothing for me -no stability improvements like 309.
And I'm almost sure unseen does not have a P5B. If i wanted to spend 60 bux more on the deluxe, I could've gotten a e6600 and overlocked it even higher on a P5B so price per clock the vanilla is better.

So, anyone tested the new bios or I will have to be the first to take the plunge again ? :p:
