AN 52 overclock

Hello all,

I'm a newbie.
I’d buy Abit AN52 on last week as AMD AM2 X2 4000+
At the moment, I overclocked at 2305Mhz as HTT 220x10,5, Vcore 1.3V in Bios (other voltage is default) and my system was stable. All temperature was under 50oC.

When I set HTT to 240 or higher, my system is still stable. (Test)
The problem, when I shutdown my system and shut off electric cable. After that, shut on electric cable and power up, my system no POST. I only clear BIOS then my system running as normal.

However, I raise up HTT to 1.3 or 1.4V and other volt (Vcore, VNB) but my system didn’t POST. I'd move RAM to 2,3,4 slot and config my RAM to DDR400, 533, but NO better.

Anyone had reached an impasse? Please help me.:banghead:


My system:
AMD Am2 X2 4000+
Abit AN52
Kingmax DDR2 512 MBx2 dual
Inno 3D 7300GT
Seagate SATA2 80GB
ACbel 450W

Sorry for my english
