I have the following:
Lenovo ThinkStation S20 Xeon W3550 Quad-Core Processor (3.06GHz 1066MHz 8MB) 4gb (2 x 2gb) udimm ddr3 1333MHz, 300GB SAS (15k) with SAS Controller Card NVIDIA Quadro 2000
I would like to add more memory, and would like to know the following:
- I have heard that its best to install memory in 3's i.e.. 2GB x 3, Is this true?
- Is it fine to mix different sizes of memory i.e.. 2GB and 4GB? Does this affect performance?
- What is the most cost effective memory at the moment is after market memory just as good? Any recommended suppliers? I have a budget of $200

Lead org is pretty much dead on here....
-yes it's best to spread DIMMs out across all three channels first, then come back and fill the channels if necessary. The performance impact if you don't fill this way is pretty small though.
-it's OK to mix densities, any performance impact in this is pretty minimal (certainly less impact than your first question regarding installing across all channels).

Thanks for the replys, would there be anything different in the following part numbers both Kingston the valueRAM is about 1/3 the price:
2GB (1x2GB) DDR3 Intel Validated DIMM
Part Number: KVR1333D3S8E9S/2GI
Specs: 1333MHz 1.5V Unbuffered Intel Validated
2GB 1Rx8 256M x 72-Bit PC3-10600
CL9 240-Pin ECC DIMM
Recemended for Lenovo S20
2 GB (1x2 GB) DDR3 DIMM
Part Number: KTL-TS313ES/2G
Specs: 1333MHz 1.5V Unbuffered
If cheaper RAM is just as good, then I might go for this:
12GB (3x4GB) - DDR3 Intel Validated DIMM
Part Number: KVR1333D3E9SK3/12GI
Specs: 1333MHz, 1.5V, Unbuffered, Intel Validated
