work. They also have the same chance of not working.
You not only have to consider the voltage, and the first 4 most popular timings, but there are also sub timings.
Plus the fact that your trying to run 2Gb modules with 4Gb modules, I'd say you have a better chance of them not working together.
And, as far as I know, those 2 companies use different IC's
just to show how many actual memory timings there are, and this is a big reason that mixed memory fails due to unmatchable timings. For example:
Dram Timing Control
DRAM CAS# Latency: 7
DRAM RAS# to CAS# Delay: 8
DRAM RAS# PRE Time: 7
DRAM RAS# ACT Time: 20
DRAM RAS# to RAS# Delay: 5
DRAM REF Cycle Time: 90
DRAM Write Recovery Time: 13
DRAM Read to Pre Time: 8
DRAM Four ACT Win Time: 24
Back to Back CAS# Delay: Auto
DRAM Timing Mode - 2N
There are also more, but you get the picture!Edited by Inteller - 8/23/11 at 1:57pm
