ASUS TUSL2-C overclock

[Papcina]

hi there

well, this mbo is quite an old model.. but it is a nice one

anyway, I have a question, do u know what is the highest speed with
TUSL2-C and the Celeron Tualatin 1.3GHz on her?

any info would be appreciated

thanks

bye

The TUSL supports up to 160MHz FSB, so you'll definitely hit
a limit on your cpu before you run into the motherboard's limit.
Speeds up to 1.6GHz are common with a 1.3GHz Celeron,
higher if you have a tB1 stepping chip and/or awesome cooling.

Yes, so I saw. A P3-S/1266MHz with oc160FSB on the TUSL, though the CPU
could go over 160MHz with special cooling. With 160FSB (20% oc) you can
still use air-cooling , so far you have a 133FSB Tualatin. I don´t
know the 100FSB Tualatin.
I would suggest you a P3-S for the TUS-L. Then you have free
possibilities of clocking (75-160MHz FSB should work). The smaller
Tualatin is more for the 100FSB Chipsets and Notebooks.

Never underrate the multi-processing (single-cpu) speed of the P3-S.
When you drive a small server or an extensive (internet) Workstation,
the P3-S can otdistance much much faster CPU´s.

Good luck with the TUS-L ;-)

The TUSL (and CUSL) has a nasty quirk: If FSB is set above
140MHz the bios automatically throttles AGP from 4X to 2X,
and decreases ram performance. Asus built this "feature" in to
assure stability, and there's nothing you can do to disable it.

Well, that's not entirely true. A French guy tried to hack Asus'
bioses to defeat this throttling:

But from reports elsewhere on the internet I'd recommend
staying at least 50 feet from these hacks.

Hi Mike!


This TUS-L have cost me so much nerves.
We got mad, trying to configure tis CHipset.
Everything is knitted other than on a BX/ZX/FX
Out from the AGP, or so. Making extra interrupts for the P3-S!? etc.
etc.......

But at least you can insert, and insert, and insert.... and it drives
somehow. Clunky but right, in digital meaning.

One time I saw a Server DUAL Motherboard for the P3-S, about 700 bucks.
Makes 50Watts CPU Power consumption and a pretty nice 2x1400MHz Power
Workstation. More than good for computing ;-)

One major issue with the CUSL/TUSL is, you can't lock the speed
of the PCI/AGP bus. I'm running a P3-S 1.26GHz, and my
Adaptec SCSI cards (2940 and 29160) choke at anything much
over standard 33MHz PCI. Even a relatively small overclock
(e.g. 148 FSB, 37MHz PCI) results in occasional failed boots
and random hard hangs. However, it's completely stable at 140
FSB/35MHz PCI and has been running this way for years. So I
settle for 1.33GHz from a 1.26GHz CPU, instead of 1.4GHz or
higher.

I agree with your opinion about the P3-S. It's a sweet chip.
Memory latency is outrageously small.
