systool misreads multiplier

[Ed Omega]

Hi,

Ok, have Epox 9NPA. When i set the multiplier to a half value, eg 9.5, systool rounds down to the next lowest whole number, so 9.5 *277 shows up as 2493mhz. FSB shows as 277 but Memory Clock shows as 263.15.

isnt that how the half multipliers work ? check with cpu-z

Hi

CPU-Z shows multiplier 9.5 correctly, as does Wcpuid. If I go into the AMD64 Cool&Quiet section in Systool, its shows the FID to be 9.5, so that part of the software is reading it correctly, tho it does not read the VID at all, always displaying 1.400V.

half multipliers are weird. the system doesnt' divide the HTT clock by something.5 to get the mem clock, its more like rounding...a half multiplier usually lowers your mem clock a little more than if you used a normal multiplier.

try messing around with it, doing the math. youll see.
