i've a question for Alonso:

i'm experiencing some weird problems running 512mb aa4t stick on Nforce2 mobos...

this is what's is written on the label of the stik i've now:


i'm running it on an NF7-s rev2... but there's no way to get it working with command per clock 1T

i'm using only that stick, no dual channel, nothing!

with cpc off they run great:


but i loss a lot of performance...

i'm not the only one with that problem... also on dfi lanparty ultra seems that some sticks doesn't works...

on this mobo i've tested only 1*512 of vdata without any problem and i've run 2*256 twinmos (powerchip) for about 1year a 233mhz 2.5-3-3-3 all the modules with cpc on!

now this stick won't work with command per clock 1t...

the only difference i've noticed is that the spd appear to be programmed in a different way:
it doesn't read the manufacture date

Code:
DIMM #1

could be that the source of the problems? all the others stick i've used where showing correctly the manufacture date
