Hello there
I'm really hoping someone can help me out a bit (no pun intended!) with this board. I am looking for overclocking stability, but as you will see below, there are other issues even at stock settings. I will summarise quickly below :
Specs :
Core 2 6420
AntecNEO 500 PSU
ATi 1900XT
Corsair 6400C4 (2Gb)
X-Fi
Tuniq Tower 120
System POSTS/Boots normally with normal BIOS settings.
System will POST/Boot with FSB set to 375, linked, 3:2 divider (CPU 3Ghz, mem 1Ghz). Will pass Prime/Orthos at this speed.
System is not stable at any other setting other than default, particularly if changing from the setting above. An increase or decrease of even 1 on the FSB will result in instability. It will also give me an 'overclocking failed' error in uGuru
before it has even tested the settings.
Unstable settings frequently hard-lock the BIOS, requiring a CMOS clear (powering down for 30 secs does NOT resolve the issue)
Hard-locks in windows require a reboot, the BIOS will then more often than not hard-lock (as above)
System will NOT post when SLI memory is enabled (in any way). Mobo sticks on C1 error (detecting memory). Memory has been tested using Extended Memory Diagnostic (inc cache) and passed 100%. Also been reseated, and tested with only one module with the same result.
Adjusting any voltages does not seem to make any difference
Temps are absolutely fine. CPU idles low 30s and under load high 30s/low 40s. PWMs are mid 40s idle and low 50s under load. Voltages are rock steady on all rails. The Tuniq Tower is set up so that it pushes hot air towards the rear-exhaust.
Have tried BIOS 1.0, 1.1 and 1.2 all with same results.
I hope someone can offer some assistance, it's driving me nuts. It
should be such a good board......
