IIRC you'll just not get the benefit of better timings from the new 4-4-4 but it will
run fine at 5-5-5 assuming no other issues between new & old. Since you're not mixing
in the same banks I think you'll be ok albeit at 5-5-5-12.
Was a time when DDR2 was cheapest, DDR3 over a 1/3 more. DDR1 @ 1GB/~$35, guess that
does work out as expensive except machines of that vintage typically never get more
than 2GB installed anyway. +1GB DDR upgrades to aging 512MB systems running XP, keeps
proving a worthwhile investment @$35 rather than replacing old general use pc's.

I'm upping some memory on a few older machines that my wife and kids can use.
One of them has Corsair Twin Pair CM2X1024-6400
(XMS6405v5.1/XMS2-6400/5-5-5-12) memory. I wanted to get the same type
and double the memory then noticed my local microcenter had one left
in their store. Before I bought I researched it and noticed the
latency on the store version is 4-4-4-12 while the memory in the PC
displays on the stick 5-5-5-12. What will happen if I use the stick
that displays 4-4-4-12 with the sticks that say 5-5-5-12? Not fully
understanding the latency aspect and what might happen if I mismatch
something.
I saw they also had a matching set to another machine I have that has
1 GB of memory, and I could pick up Crucial Memory Crucial 2GB DDR-400
(PC-3200) DIMM Memory Kit (Two 1GB Memory Modules) which is exactly
whats in the machine now other than the 2 sticks in there now are
512mb. BUT... it seems the older ram is more expensive? Is it just a
supply and demand this?
The above corsair memory is is $20 cheaper than that older Corsair
memory... Just an observation.
