Hi All,

I’m struggling with getting any significant overclock from my new system.

Config:

Asus P5B Deluxe WiFi – 0804 BIOS
D 805 CPU
2 ea. 1GB Super Talent DDR2-800 RAM [4-4-3-8]
WD WD1500ADFD 150GB Raptor HD
Tuniq Tower 120 CPU cooler
ATI x1950XTX GPU
Highly rated 700w power supply [sorry, don’t have brand and model # handy]

In my attempts to get ANYTHING I have set CPU vCore as high as 1.5v, RAM and most other voltages to max, RAM timings to 5-5-5-15, and other BIOS settings to the typical overclock recommended settings and cannot even POST with the CPU frequency above 140 [default is 133]. All temps look far below pain levels and the system seems to be rock solid at default settings.

It would appear to be memory interface related because I can POST at 166CPUF if I set the memory to the lowest possible multiplier [~DDR2-498] although Windows XP will not boot. As soon as I start moving the RAM speed back up it fails to POST. I’m not even getting close to the rated DDR2-800 with EITHER stick of this RAM so I can only assume it is a problem with the MB or this BIOS version.

Any input would be appreciated, particularly if you have good or bad experience with this MB and BIOS version.

Regards,
Craig
 
Please, just 1 thing before I try and help you...

You say you can't post at more than about 140 FSB?

You shouldn't be TRYING 140 FSB... So, I gotta know the real number! Are you sure you're changing what you think you're changing?!
 
Allow me to restate...

I am altering the CPU frequency. The locked multiplier for the D805 is 20 and the BIOS defaults to 133 - 2.66gHz.
