Upgrading existing systems - keeping existing RAM as well

[Sim1626861419]

I have two systems, both based on an ASUS A7N8X-E Deluxe mobo

 

The first system (let's call it A) has an AthlonXP 3200+ CPU in it (400MHz FSB), plus a VS1GBKIT400 pair of PC3200 512MB modules.

SPD reports 2.5-3-3-8

 

The second system (B) has an AthlonXP 3000+ CPU in it (333MHz FSB), plus a pair of VS512MB333 PC2700 512MB Modules.

SPD reports 2.5-3-3-7

 

The A7N8X-E Deluxe has 3 memory slots.

 

Now, I want to upgrade system B to 3GB RAM (long story, don't ask). Obviously this means I will need three 1GB modules.

 

The store I usually buy my memory from has kits of TWINX2048-3200 (3-3-3-8 I think the Corsair site says) and TWINX2048-3200C2 (2.5-3-3-6 I think).

 

My thought is ... to get system B to 3GB, I would need to buy two of these kits (two of the same that is - probably the TWINX2048-3200C2), and then I would have a 1GB module left over that I can throw into system A.

 

Here's what I'm hoping to do:

 

System A (333MHz FSB)

 

3x 1GB modules from the two TWINX2048-3200C2 kits

 

Q: the PC3200 RAM should work okay with the 333MHz FSB right ? I know it won't be running at full speed, but I don't want to change the AthlonXP 3000+ CPU from that machine.

 

System B (400MHz FSB)

 

1x 1GB module left over from the TWINX2048-3200C2 kits

2x 512MB modules from the VS1GBKIT400 kit

 

Q: should the 2.5-3-3-8 from the VS1GBKIT400 work okay with the 2.5-3-3-6 from the TWINX2048-3200C2 ?

 

Thoughts or suggestions ?

Yes, and then no, in that order.

 

Order one 1 GB stick vs. an extra twinx pack.

Bummer (on the second part).

 

Thanks for the quick response, Wired !
