which RAM for Dual Opteron?

[Beno]

I need 4GB RAM for my Tyan S2885 dual Opteran motherboard.

 

ny recommendations? I was thinking of Dual DDR, PC 2700 ECC registered modules.

 

Is it better to go with 8 X 512 or 4 X 1024 MB?

If you have a 248 or 250 processor, they support DDR400 - which is PC3200 I think. I have 2Gb of Corsair XMS3200 ECC registered - 4 x 512Mb on a Tyan Thunder K8W board. I think 4x1Gb sticks might be the way to go (leaves room for more later!), but have a look at http://www.tomshardware.com and this site:

That seems to be pretty in depth on setting up a good dual processor system - it's about a year old now, but still relevant I think.

Best of luck

alrite - I've the CPUs (two 248s), Tyan S2885, Corsair XMS DDR400 PC3200 (4X1024MB).

I need a Rolls Royce ATX case and CPU fans, best money can buy.

 

suggestions?

Case - Lian-Li aluminum, choose on size from http://www.newegg.com/app/ViewProduct.asp?submit=manufactory&catalog=7&manufactory=1375&DEPA=1&sortby=14&order=1

 

I like http://www.newegg.com/app/ViewProductDesc.asp?description=11-112-508&depa=1

It's a lot like what I have, bit bigger though, includes 4 fans and space for 2 more (your dual CPUs are going to want a lot of cooling).

 

You'll need a VERY GOOD power supply with all this, in the 500W range and with a lot of amps (minimum 20) on the +12V rail. Look at http://www.newegg.com/app/ViewProductDesc.asp?description=17-103-918&depa=1

 

As for CPU fans - look at http://www.thermaltake.com/coolers/venus/rs/a1838.htm

The all-copper heatsink and thin fan design is more efficient than the stock aluminum models.

 

Also, when you put in the heatsink you should use a thermal compound. I use http://www.newegg.com/app/ViewProductDesc.asp?description=35-100-007&depa=0

It's a very think, stick compound - the idea is to get a bit on the plate of the heatsink where it will contact the CPU's metal backplate, wipe it on (I recently used the thick glossy paper on the AMD brochure that came with my Athlon64 and it worked very well then pretty much wipe it OFF so you leave the thinnest layer that is without gaps. The stickiness of the stuff makes it pretty easy to do this. The thermal compound is basically to take the place of the microscopic air gap that results from imperfections in the metal surface, and replace it with something much more conductive.

 

Did the Corsair RAM come with its own heat spreaders? (These are metal plates that go over the chips.) If it didn't, you might want something from this list: http://www.newegg.com/app/ViewProduct.asp?submit=list&catalog=129&DEPA=1

(the ones that are a log piece of aluminum or copper on each side of the stick, clipped on, look like the way to go - they have some that are a piece glued to each chip, and those look... stupid.

Beno,

 

Take a look at the new Tyan Board 2895. It has dual PCI Express.
