good work!
try using 2.5-3-3-7-2
do you think you can do Vagp, Vio, and Vcore mod?
the basic principle is to make FB pin thought that Vout is too low.
if you can't find FB, Vsense is to look for. if you find Vsense connect to Vout directly, it is a more difficult mod (see how Jeff mod Vddr on 8RDA+ in this forum)

Couldn't find an electronics store that was open today so I will try this myself on my PX845PEV on monday if all goes well.

Could you guys post photos of exactly what chip to mod and what pins to attach the leads of the pot to? I got a couple of 10k (and I think 47k?) pots but I never got around to doing this on the Athlon boards.
Yeah, I notice the PX845PEV PRO doesn't like 2-2-2-6. I can do DDR426, 2-2-2-5, then maybe DDR434, 2-2-2-6, then have to use 2-3-2-6 from DDR434 to 466.
I've gotten a TwinMOS 5-ns Winbond stick to DDR461, 2-3-2-6, and Corsair XMS3500 C2 to DDR466, 2-3-2-6, but can't go higher with either stick stuck at 2.8 volts. Same # of errors no matter how relaxed the settings.
Interestingly, I recently picked up a used XMS3500 C2 stick in Japan and this one does DDR450, 2-2-2-5! But it will not go any further like the other sticks. So I need more than 2.8 VDIMM.

clevor,
on the first page of post, we detail the mod and chips...vr between pins 1 and 2, set to 50k at first, adjust down as you watch multimeter. Solder neatly as the pins are pretty small.

Charlie, there are pics of two chips, one is long and rectangular and has pins on each side while the other is small and square and has 5 pins on one side only (looks like a MOSFET). Which chip do you mean?
-
Yes, the one with 5 pins on the same side. Study the schematic and proceed with caution

so, can“t see pictures :-(
wheres the problem exactly?
