Need some help OC'in a 1.2ghz Abit KT7A

[unpluGGedddd]

Hey, I just got a new computer... I got a Abit KT7A, 1.2ghz (AXIA) and Kingmax PC150 SDRAM 256mb, with a Geforce2 Ultra

When I try to overclock my FSB past the default, my monitor just shuts off when it restarts... Then I have to keep turning my computer on and off (or clear cmos, which I don't like to do)... I can use the default ones like 1400 (133), 1333 (133), and it all works good, but when I do it myself... 9.5 x 150, 10 x 140, 10 x 145.. My monitor just shuts off!!! (I have the latest bios)

I've tried all the voltages 1.75-1.85

I bought this new RAM hoping I can get my FSB, so if you know what it wrong, please help

Thanks

My KT7A/1.2 AXIA B doesn't like high FSB overclocking(137 with the most aggressive memory timings using Infineon ram). Have you had any luck raising the multipier?

try using a more moderate RAM timing....

your memory should be able to handle FSB o/c just fine my Kingmax 150 could run 155 no problemo
what is your cpu and mobo temp...

Try increasing ur FSB in small increment. Jumping from 133 to 140 would lead u no where.

1. Up the FSB until the system becomes unstable or no POST.
2. Up the vcore to 1.85v
3. Up the I/O voltage to 3.45-3.60v. (default is 3.3v). I think u only select either one on this mobo.
4. Once ur sustem is no stable, u now know the limit of FSB increasement in ur system.
5. Set RAM timing to CAS3.
6 Up the FSB from where u stop at step 4. The FSB now should go higher.
7. Once ur system becomes unstable again....tht's ur max FSB limit.

Enjoy. Do post back for further Q's. If u dunno wht I'm talking.

I have the same setup as you do(KT7A 1.2 AXIA), and I run it at 1333 MHz. I can't get it to POST any higher than 1.4 GHz. It's posted at 1.4, but then it died when I was in windows. Anything lower works, such as 1390 (139 MHz)or 1380 (138 MHz). I think your problem is raising the bus speed too high.
