FSB x HT multiplier = HT bus speed

for nF4, HT bus speed should maintain below 1000mhz
for nF3, HT bus speed should maintain below 800mhz

hehe.... TCCD is the best for Sempron when paired with mobo with low max Vdimm

If i not mistaken...DFI NF4x got prob if running 2 stick of ram rite?
You wont be able to change ur divider or wont hit very high. Anyway...if you stuck in 280-290 region..is very clear that it the ram that pulling you backward.

wanna change mobo with me and tried out?

it said,

Then, Overall HTT Bus Clock = Reference Clock * LDT Multiplier * 2
my HTT bus clock is: 285 * 4 * 2 = 2280Mhz

Ops! it is out of the safety range, the system is safe or not?

i tried to lower to 3, PC bootable but XP failed to logon. With 285, i can run the XP fine, included install the Os, running the games and benchmark for a night...

MSI k8n neo3, the vcore is unadjustable...

you mean the nforce chipset voltage?
