XPS420 memory

​ Hello! ​
​ ​
​ Anyone know the maximum memory volts for the XPS420 motherboard (0TP406)? Standard is 1.8v for the PC5300 memory, will it cope with PC6400 memory with 2.1v? ​

xps420,

The XPS 420 can use both PC5300 667MHz and PC6400 800MHz memory. But i would not mix them.

HT212 DIMM, 512MB, DDR2, 667M, 64X64, 8, 240 pin
WM551 DIMM, 512MB, DDR2, 667M, 64X64, 8, 240 pin
PN424 DIMM, 1GB, DDR2, 667M, 128X64, 8, 240 pin
WK007 DIMM, 1GB, DDR2, 667M, 128X64, 8, 240 pin
KU354 DIMM, 2GB, DDR2, 667M, 256X64, 8, 240 pin

WG440 DIMM, 512MB, DDR2, 800M, 64X64, 8, 240 pin
NY190 DIMM, 512MB, DDR2, 800M, 64X64, 8, 240 pin
CM633 DIMM, 1GB, DDR2, 800M, 128X64, 8, 240 pin
XG700 DIMM, 1GB, DDR2, 800M, 128X64, 8, 240 pin
YG410 DIMM, 2GB, DDR2, 800M, 256X64, 8, 240 pin

Doesnt sound like this was a real answer! I ran across the same issue.
 
I have 2 GB that came with Dell DDR2 6400 800mhz. But I tried to upgrade using some Kingston Hyperx (?) and then my system was reading only 667mhz for the Ram.
 
Now I put that new ram into a system I just built and it actually does read out at 800mhz. I think that the motherboard ( 0TP406) has different settings setup to the voltage to make you buy the DELL Memory, or you lose performance because the stuff you buy will need the higher voltage to get the speed
