Asus P5B (vanilla) Overview

[Shaggy]

Right now my E6300 runs 100% stable at 500 w/ 1.45vcore (board is unmodded).

I'll see if it posts with spread spectrum on and if so see if the voltage will lower.

If you're looking for a decent value with C2D via overclocking, I'd grab an Abit IB9 and an E4300 or the upcoming 84usd E2160 to try for 3.4-3.6GHz. You're starting with a 9x multi and don't need a huge FSB for a decent OC.

Abit IB9 74usd with rebate-

E4300 118usd-

Recent review of the E2160 including the E4300 below. It's not in English and you may still read the benches on each page fine.

I used to have a o/c wall at 350FSB with my old ram. But with my new Ballistix PC6400 ram, it does 470FSB at stock voltages, with the same settings.

So, I don't think, comrade, your Ballistix 5300 is the problem. Those are Micron D9 chips and probably the same chips that are on the expensive PC1000 modules (but perhaps binned?)

I would make sure your ram timings are at default (ram spd enabled in bios) when trying to o/c. You can tighten them later after you find your max. FSB.

At 400FSB, I think you may still be at the 2:3 ram divider, but at 401FSB and above, its 1:1, where it is much easier to o/c.

I would try 410FSB with the cpu voltage boosted to 1.45 volts, (which in reality may be only 1.38 volts, considering the vdroop of these boards.)

Then hopefully move your way up in 10FSB increments up to your max. o/c. Voltage will have to substantially increased to get above 490-500FSB. I'd watch your temps carefully for any sustained usage over 500FSB.

My system runs stably at stock voltages at 470FSB (Cpu 1.3875v in bios, which is 1.32v at the cpu), which equates to a 3.3GHz C2D. But this system was a dog with my old ram.

I reached 525FSB with the bios cpu voltage set at 1.55v, the memory voltage at 2.1v, and the FSBterm voltage at 1.45v maximum. All the other settings are on Auto. This o/c caused extremely high cpu core temps and other parts, I'm sure. But at 470FSB is cool, stock and stable.

Spread spectrum did nothing for me. Same system stability. Orthos started failing after a few hours like it normally does.

Thanks man, but I tried loosening the ram, and setting it to default, I am 100% sure it is not the ram, my ram has the D9GMH chips on it. I tried CPU voltage at 1.45V and still nothing. Anything above 400 the pc won't boot into Windows. I hate this board.

What revision P5B do you have, and what voltage are you running to your memory?
I used to have a 1.03G P5B, and I had to have max vdimm to boot into windows on my 8x400 (3.2GHz) overclock. I then ended up getting a replacement 1.04G P5B, and the system would not boot into windows unless I had my vdimm set to 1.9v. Go figure...

I have the 1.03G and I have my ram at 2.1V

I got over the "wall". The problem WAS the ram... I feel very stupid now But anyways, I didn't loosen the timings, I just changed them to 5-5-5-15 4-35-4-10-6-10 which are even tighter than the stock timings. So how far did this get me? I didn't try much but it easily went to 3640

Nice!

What bios are you using?

I am using the 1102 bios.

Hi guys, need advice/help.

Bought CORE 2 DUO E6600 for my P5B today, replaced celeron 2,53 and started having problems with WinXPSP2.
Here details, first boot ok winXP loaded, everything seemed to work, run game cossaks 2 it crashed PC restarted. Here all hell broke lose. WinXP offered me to start in save mode few times restarting PC as I tried to proceed. When I succeeded to load winXP windows explorer kept crashing and freezing.
To make it short I updated to latest bios 1202, and reinstalled WinXP (installation was horribly slow). Still problems, reinstalled winxp twice.
Upon restarting freshly installed Win get this message "windows could not start because the following file is missing \windows\system32\config\system
you can attemt to repair this file by starting CD..... (restarting PC helps to get to WinXP desktop)
I'm starting to worry I got defected CPU

Please any help appreciated.

Vasilii.

hmm not sure, maybe load bios defaults coz those cpu options may need to be changed, i dont mean the speed ones but like those other ones that have disable and enable, theres like 5 or 6 of them, just try reset bios anyway

[LisijBOB]

hi.
can somebody test this version of SetFSB for P5B Vanilla ?
select the clock generator to ICS9LPRS552AGLF

download links:
http://cp.people.overclockers.ru/cgi...etfsb20b9e.zip
or Rapidshare:

please reply to me if it works. if not, please make a screenshot of "diagnosis"

No Function.
Diagnostics not works either

Well, it show my cpu clock and fsb, other than that it didn't work when I tried to set the fsb higher...

It seems problem was with RAM memory, I have two each 512MB, I changed one from socket 2 to 3 and in bios set ram from auto to 677MHz so far no problems.

Check Ultra box. Could you try again?

[tuanming]

Check Ultra box. Could you try again?

When I check Ultra box the number change from 862/760 to 487/760... and then i tried to set the fsb my pc froze even without checking Ultra..

[AliG]

This seems like it should be a nice board, though it just looks like a striker with a different nb to me

I wonder what the max fsb this thing can reach compared to the striker's is

[abo333]

When I check Ultra box the number change from 862/760 to 487/760... and then i tried to set the fsb my pc froze even without checking Ultra..

Does SetFSB 20b9e work correctly with checking Ultra?
and then, Could you try "Set FSB" button?

[tuanming]

@abo333

I did it before and it seems that SetFSB 20b9e does not work for P5b...

Hmm..., Thanks

[Triskelon]

cant find any drivers, dont I need more then for audio, lan and Wi, and the latest bios, aint there any other driver for the board? Would be nice if anyone got a link, didnt get teh cd or manual with the board.....

[The Coolest]

They are all on the ASUS website..

[Triskelon]

They are all on the ASUS website..

Theres nothing for the chipset.......

Also would like to know how to change the fsb without changing the RAM, Oced on a p5n-e sli and then I could choose Unlinked and Linked. Cant find anything like that.
