Is the KK266+R XP compatible

[jbslow]

Is anyone running this setup without a problem?

IWILL KK266+R (?bios)
XP 1600+ / Volcano 7
512megs of PC133
Gainward GF2 Tit.
Antec 300w psu

The system just reboots randomly from what I understand. The system worked fine with the Tbird 900 it ran before so its more then likely the chip.

I looked at the IWILL site but found no XP bios updates for this board. There was an update for the KK266R and the KK266+ or atleast Micro Code update.

I forgot to mention when I put a 1600+ into the mobo and reset the cmos the chip boots up as a 1.47G (11x133) fortunately I ulocked this chip and we could set it back down to 1.4(10.5x133).

The Plus R came out after the KK266-R. It probably already had the code for the XP's.

Needs a BIOS update I think.
Mine did.
What PS do you have? How much Wattage? 250w? 300w? 350w?
Some of the 300 are marginal at best.

What bios are you running? I'm not sure what the problem is actually he put athlon 900 back in the system and told me the comp wount even boot now. He's useing some 512meg pc133 I wonder if this could be a problem I wish I had so good pc133 to test in the system.

300W Antec 3.3v + 5v = 180w max output so its a good 300W psu.

I had regular lockups after upgrading the TB CPU in my KK266-R to an XP 1800+. After reading some threads, I dropped my voltage to 1.65 and it's working like a charm.

It appears the problem is overvolting the CPU, not a lack of power from the PSU. I noticed some strange things with my TB CPU when I played with the voltage. Setting the voltage on the CPU to 1.8 was really 1.84, 1.775 was really 1.82, etc.

My voltages are---3.3=3.39, 5=5.05, 12=12.43 all while running SETI.

Edit: As per my other posts on the subject, further experimentation resulted in upping VIO by 5% and VCore is working fine at 'Auto' (1.79v).
