TerraRaptor - CUSL2 @ 239.6MHz - 239.6 MHz Reference Clock

[Stermy57]

Terraptor i have a problem with my CUSL2, it blocked me at 220Mhz but i not understand why -.-

The CPU can go on but the mobo blocked me also if i set on setFSB or in the BIOS 230Mhz

the mobo run the OS run well but CPU-Z show me only 220Mhz

How did you do?

 

[TerraRaptor]

haven't ever met this problem. Tried another bios? Does aida show the same?

i tried all bios for CUSL2 even the "evil inside Bios"

Maybe is a bug of CUSL2 but not for all version...

I have ASUS CUSL2 rev 1.02 with green capacitors...

You? thanks terraraptor

i don't remember capacitors that my cusl had - soldered other ones. Try cpufsb then - maybe it will override the limit.

Depend on the clockgen you have.

i tried it later thanks terrraraptor

Uhh i not understand, can you explain me?

Thanks ney

On the motherboard there is a chip that is called a clockgen (clock generator).

 

This is a clockgen for exemple:

 

 

If your clockgen can only go up to 220 MHz then you can't do anything about it, you are "hardware" limited

i yes i know it

CUSL2 have ICS 94201CF

So if all CUSL2 have this clockgen, why my CUSL2 can't go over?

[Christian Ney]

Maybe not all have the same one that's the thing

 

Had several times the exact same s370 board (rev) but all had a different clockgen. So maybe it's the same for the CUSL2.

uhhh interesting...

maybe is true....

[Turrican]

just put a heatsink on the clockgen and cool it as good as possible, then the "hardware" limit is no problem anymore. it will clock way higher then.

[Christian Ney]

You can't bypass like lol

[gigioracing]

also my 2 Cusl do max 220 fsb :-(

[Christian Ney]

Is it a limit in the software/bois you can set or you can set over 220 but it doesn't work/crash ?

you can set a fsb over 220Mhz but it doesn't work....

I can do a video if you want

[Christian Ney]

When you say it doesn't work, you mean ?:

- doesn't apply

- crash

- does nothing

 

What tools have you tried, do you have higher values than 220 in the BIOS ?

I have this problem like gigioracing even when i use Celeron Coppermine-128 with bus at 66Mhz...

If i start from 66Mhz the mobo blocked me at 108Mhz but if i start from 100Mhz FSB i have no problem and i can go over the CPU's limit.

I have this problem with setFSb but even if i set the fsb on the BIOS is the same

The problem is that doesn't apply

you set the fsb but does not change...

[Christian Ney]

Hum,

 

Try this http://www.cpufsb.de/index.html

 

Even if you set 225 MHz in the BIOS you have 220 in Windows ?

[Stermy57]

Hum,

 

Try this http://www.cpufsb.de/index.html

I will try it later

 

Even if you set 225 MHz in the BIOS you have 220 in Windows ?

 

Yes, and sometimes even less than 220 Mhz... blocked me at 218/219Mhz it's very strange

I had the same problem with my CUSL2-C few months ago. I tried to get decent SDRAM clock (2:3 divider) and it was impossible to pass ~ 100MHz FSB. When I set more, the real clock remains at 100 - checked in CPU-Z, aida64.

 

HW:

 

CUSL2-C rev. 1.02 (ICS 94201DF), modded "evil inside" BIOS

PIII coppermine, 133MHz FSB - tried more of them, same results

PC133 CL2 SDRAM - validated at > 170MHz on different MB
