Motherboard: Biostar TA770 A2+
RAM: OCZ DDR2 PC2-6400 Gold Series
PSU: SilverStone ST50F (500W)
VGA: Gigabyte GeForce 8800 GT TurboForce Edition
managed to OC till 3.0GHz (240HTT × 12.5)
more info in table below:
for multiplier ×12.5 --> HTT = 240 max
no matter what voltage i use (cpu, memory, ht, & nb/sb) still can't boot if htt were to be increased
no matter what memory divider i use still can't boot if htt were to be increased
for multiplier ×11-8 --> HTT = 267 max
same no matter what voltage i use (cpu, memory, ht, & nb/sb) still can't boot if htt were to be increased
no matter what memory divider i use still can't boot if htt were to be increased
for multplier ×6 --> HTT = 280 max
same no matter what voltage i use (cpu, memory, ht, & nb/sb) still can't boot if htt were to be increased
memory divider on DDR 400 --> 267 max
memory divider changed to DDR 533 --> 280 max
memory divider on DDR 800 --> failed
so, anything i'm missing?
seen one review by BCCHardware
OCed X2 4800+ (2.5GHz):
- up to 380 (HTT) on ×8 multiplier
- up to 240 (HTT) on ×12.5 multiplier
btw, for AMD, which is better:
- Higher HTT × Lower Multiplier, or
- Lower HTT× Higher Multiplier?

. The comp just wudnt boot. Its not the proc or memory holding me back as I have lowered the multiplier to 5X, set HTT to 3X, loosened all the ram timings and set the mem to ddr400, and i also pumped the chipsetvoltage to 1.3v. Ok......so then i tried using my usual OC setting of 2.9ghz with the fsb at 320, and it worked! So i tried again, this time I left the cpu voltage at oc levels and tried. It worked!! But I had to keep increasing cpu voltage as i increased the fsb speed even though my cpu was running at low speeds
