Can I use a 2GB DDR2 800 MHZ RAM of latency 4-4-4 with an identical spec RAM except latency is 5-5-5? if so, with what result?

[Vasudev_L]

I have Windows Vista OS with 2 GB RAM in one slot and 1 GB in the other of only 2 slots. Both are Transcend DDR2 of 800 MHz with identical 5-5-5 latency. I would like to upgrade to 64 bit Windows 7 with 4 GB RAM. if I replace the 1 GB RAM in one of the slots with a 2 GB RAM of same brand and specs as the 2 GB RAM already in the other slot but of latency 4-4-4, will my desktop work and if so with what result? Thanks in advance for your advice. Vasudev

Can't guarantee it would work at all but if it would, than all the memory would be set to slowest one (Cl5-5-5) which is negligible and offset by amount of RAM.

You are welcome, all you can do is to try, as I said no guarantees for such mix to work but can happen.
