Epox 8K9A Vdimm mod

[Fewture]

After this bench I want to try higher, but I think there is not enough juice going to the mem.

Now I think the chip is this one:

ICS 93718CF
Datasheet: http://www.icst.com/products/pdf/93718.pdf

Can anyone help me with this mod? Is it the right chip? There is also an Attansic ATXP1 on there, but I don't think that is the right one..

Tnx guys :toast:

8k9a has half of the chips of the 8k9a2, even the vcore chip is diferent!

on the other side, maybe it will be easier to found out the vdimm mod on 8k9a
:D

this weekend i'll do some measurements.

i think i need some help... VIN seems to only give the voltage, not regulate, what if i connect VOUT to ground? what resistor? :rolleyes:

9173 isnt the right chip (its the VBT) isnt there anything below the Dimm clips near the NB ?
