[Bobbyeyes]

does anyone know the jumper sequence for 175 fsb (jumper block)
on any of the Asus p4b series mother boards?
i randomly attempted , but could not get lucky

thanks!

Yo Bobbyeyes -

I would like to converse with you but don't know how. You don't have a profile here.

I have a P4B533-VM with 1003 BIOS and it boots my 1.6A into 2.4Ghz w/150Mhz bus. It can run Prime95 forever; however, it doesn't run Quake 3 Arena or do the Direct 3D Video Acceleration Test in dxdiag without locking up. I have to lower the system to 2.224Ghz/139Mhz to get it stable.

Someone told me you have employed a bunch of tricks to be able to vary the system voltage (I'm stuck at 1.5v) and some other things, like bus ratios. Can you share any of these things with me?

Thanks.

YO..
you need to wire mod for 1.7 volts.. not higher...i had a 1.6 that sang at 175 mhz
now it crawls at 137 mhz (poor me i know)voltage was too high!!
you also have the later version of this board(1003bios)
you only have a 1:1, and 3:4 mem ratio wher auto =1:1 and 1:1=3:4
DISABLE onboard sound, but enabling onboard usb is fine
keep the usb voltage at normal
i ruined a vm w/ my memory voltage mod... it worked for weeks, then the board acted flakey(all that testing)
now that you are running @150 , you need to be absolutely sure your mem can run @200 fsb@Vmem default.
i think 1.7 is safe(actually a little higher if you swear by asus probe)
and it should get you to 150 stable

quake is kids stuff...prime is even whimpier..

if you can play serious sam, or moto cross madness 2,w/out issues, then you are real stable
they are both system resource taxing
not video card intense.

I flashed to 1002 to see what was up...

I thought 1.7 was for vcore CPU voltage, not RAM.

What now?

 

[Bobbyeyes]

keep the mem timing @ 2.5 3 3 7 ,or you mite not be able to boot

 

[Bobbyeyes]

do you know how to get the V core to 1.7,with a wire?
a blow hole or a good heat sink is recommended

What is the performance hit for 2-3-3-7 vs. 2-2-2-6?

 

[Bobbyeyes]

when mem is set to auto (1:1)
sandra reports a slightly better score w/ advanced timings, but when you are running 3:4
you must relax the timings or you will not get to your desk top
