I have just about had it. I have tried everything, even underclocking!!! There are some serious stability issues with this board. It first started when installing my system. When connecting the IDE devices ( I have 1 IBM GXP120 80GB , 1 Pioneer DVD , 1 LiteON 48x CD-RW , 1 ASUS 52x CD-ROM ). I connected the HD as Primary Master and the ATAPI devices on the other channels ( not using raid ). The BIOS would not detect my HD. To make it work I was forced to connect it as primary slave and it detects it as UDMA 2, (ATA 33). OK. I thought ill get it up working first and then ill fix it properly. My first lockup came when installing WIN ME. Exactly when reaching 63% of filecopying. At the moment my XP2000+ was running 10x166 fastest timings (this means i was not out of spec). So i restarted and started over with CL 2.5 . OK. I managed 2 get it up and running . So I want back to CL 2. The system worked fine 4 about an hour or so and then it locked up. I cheked my temps ( 26 case, 36 CPU ). Went back to CL 2.5 ( Just notice that on my Epox-8k3a+ I runned this stick at 178FSB fastest timings @ stock Voltage all day long.). Runned under load 30min or so and other lock. At CL3 it would not even post. I have tried BIOS 1008 through 1010 beta at FSB's 133 & 155->166 with multiple x8 -> x12,5. I just cannot belive that my Stick of samsung that OC great with my 8k3a+ is the problem. What I am sure of is that it's a bad overclocker it would not even post at any Voltage what i used to run at stock voltage with my old board
