update regarding my post from earlier today. i guess it is time to spread some
thanks to railer and ironcheff. being the lazy smartass (?) i am i incorporated
both their recommendations in one go and went upping the clocks.
so with both fixes in place i was able to up the fsb once again to >300 and was
actually able to bench aquamark3 at 9x306 (2754 mhz) with the geforce mildly
clocked at 400/1150. so i guess we can state that this works. which of the two
fixes finally made this possible, i don't know. suffice to say that it works. this
was done running the mem 3:2 (not good). anyway, i had to ump the pci-agp
fix up to 36/72 in the process, since the rig went into supercrawl mode once
i passed 304 mhz fsb at those settings i used.
now what i need to figure is how to make this work with my ram. so far i've been
able to go up to +240 on the ram - which really isn't that much of a feat, con-
sidering it's bh5 (2x kingston 512mb sticks, them being doublesided doesn't help).
but then again, with this p4p800-se my vdimm drops considerably under
load. vdimm mod is done via lm358 and resistance is set to 0, so whatever is
left of the 3.3v rail after some regulation, goes to the dimms. by bumping the
3.3v to about 3.5v on this last try, i had about 3.27-3.3v working the rams
under load. idle is ~3.4v...
i need to stabilize the vdimm, because 0.12v max droop under load is not to
be tolerated. makes benching some sort of a gamble. ideas to make this
happen are appreciated. btw psu is an ocz powerstream 520w - and i doubt
its 3.3v line takes a dive under load, when it didn't buckle running my xpm
@3.1ghz loaded.
