Trying to Overclock T-bird 1133 w/ Asus A7V133

[Hezrou]

I've recently been trying to learn more about computer hardware and decided to overclock my Althon T-bird 1133. I have a Asus A7V133 (1.05 PCB, 1009 BIOS Revisions). I'm currently using a multiplier of 8.5x with a 133 FSB. When I try to overclock my CPU from the BIOS (I change the dipswitches on the board to jumper free mode and JEN to default) using multipliers I always get POST errors and I would have to go change the jumpers back to my default settings to fix it. I can overclock my CPU up to 1190 using 8.5x multiplier and FSB of 140, anything higher and some games/benchmarks will crash with no message.

I skimmed through "The Book of Overclocking" about overclocking and I seem to get in the same problem. When I try to overclock with multipliers and get the POST error, it would make a long beep repeating itself. My CPU temperature is around 50 degrees C, my power supply is an Enlight 300 watt. Could anyone help me our or give me a suggestion. I would like to be able to learn more about overclocking before I buy a new CPU and overclock that. I haven't had any problems overclocking my friend's AMD XP 2400+ w/ Asus A7N8X.

Thank you.

make sure you have good memory when you're doing the fsb overclocking because your memory timings are gonna go up as well.

you could test the limits of that by tuning the mulitplier way down and start bumping up the fsb speed. if you're still getting these problems at the over 140 fsb settings i'd say you need some better chips.

also, are you doing all this at default vcore? you may want to try upping that slightly.

is 50 degress your idle temp? that seems high to me. i've got a 1GHz T-bird @ 1.35GHz (9 * 150) in my a7v133. my voltage is @ 1.85 iirc, and the idle temps are about 43-44, full load brings it to low 50's.

Yeah my VCore is at default. I checked my CPU temp after I left my computer on for about 24 hours and running 3DMark2001 SE/3DMark03 about 4 times each during that time. The temperature was 52 Degrees Celsius after running the programs at the end of the 24 hour testing.

By the way, thanks for the advice, I'll try it out the few things.

did you unlock your cpu via the pencil trick?
