Hello, Paul!

I can see I should have been more specific on the MB - it is a
A7V8X. Does that present a problem your advice?

Thanks.

You identified your motherboard in the subject line, and
I responded based on that. Try searching in Google
for some other opinions - using "A7V8x two sticks"
as search terms, I get about 198 hits.

You can play with Vdimm a bit (2.75V) if the memory shows
errors in memtest86.

P You can mix and match DIMMs on a single channel board. The BIOS
P is supposed to find the slowest stick and set the timings
P based on that. (Sometimes this doesn't work out as planned, and
P then what you try, is swapping the two sticks. If the sticks
P were in slot 1 and slot 3, try moving 1--3 and 3--1.)

P The best slots for two DIMMs are slot 1 and slot 3.

P Your motherboard has a limit of two double sided sticks at
P PC2700 rates. That doesn't mean you are forced to buy PC2700
P memory, it just means that the BIOS setting should be DDR333
P for the two stick case. Two PC3200 sticks could be used, as
P they are backward compatible with the PC2700, PC2100, PC1600
P rates. (The only time this isn't possible, is when using a
P microATX motherboard that has no manual DIMM settings in the
P BIOS. There are motherboards that will read the SPD and set
P the clock too high, and the motherboard will be forever
P unstable. As long as your motherboard has DIMM clock and
P timing adjustments, a pair of PC3200 sticks can be
P "dialled down" to PC2700.)
