How to get lower dividers (166/200) working with 3500+ and G.Skill 2T sticks?

[Spacehead]

I can run these G.skill F1-3200phu1-512nt
at 1:1 but when I try to boot to WinXP with lower divider, ie. 180/200 or 166/200 , it doesn't work.

In WinXP I can set divider to 180/200 and raise my HTT to 273 , to get my CPU 3 Ghz.

I would like to try if I could OC this Venice a bit more, but 166/200 doesn't work, neither it goes into WinXP or it could be changed from WinXP.

Damn, 3,1 Ghz would be within reach...

what do you have max async latency and read preamble set to? dram response and the two drive strengths would be nice to know as well

[Spacehead]

Max Async Latency and Read Preamble are on auto, ,,, 9 ns and 6.5 ns

Dram Response = Normal
Drive Strenght = level 8 (normal)
Data Drive Strength = L1 (reduce 50%)

I could try to mess with these.

try changing the drive strength to 5/3

It works in WinXP, but sadly it won't boot to XP when those are set on BIOS.

With a quick test it passed 3DMark2001 @ 3,23 Ghz
It is a shame that I haven't got it yet to boot with dividers.
