S20 Memory upgrade

Hi,

 

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

 

Thanks,

Re: S20 Memory upgrade

1) yes it is best to install ram in a bank of three, so 3 x 2 gigs, and then 3 x 4 gigs etc.

2) Yes it is okay, but it is best to do it in triplet of similar size.

3) I use Kingston ECC ram of 4 gigs size, 6 x 4 gigs, each stick costs about 60 dollars. 2 gigs is about 24 dollars.

Re: S20 Memory upgrade

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).

Re: S20 Memory upgrade

HI,

 

Thanks for the replys, would there be anything different in the following part numbers both Kingston the valueRAM is about 1/3 the price:

 

ValueRAM

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

Re: S20 Memory upgrade

i got the value Ram and the more expensive KTL version of the ram, they both run okay in my S20.

Re: S20 Memory upgrade

So, did KVR1333D3E9SK3/12GI work fine with your S20?
I'm also thinking of buying it, it will help me a lot if you let me know how it is, thanks!
