2 sticks of RAM too much for PSU?


At work, I'm setting up a server with a Tyan S-2882-D Motherbard, and an Istar USA 460W power supply. The issue is RAM related. I'm trying to install 2x 1GB G.Skill  PC3200 DDR SDRAM. When I boot the PC with both sticks installed, the PC does not boot(nothing shows up on the monitor nor is there a POST error code..). I tried doing this with only one stick and it worked. I then swapped sticks to make sure it wasn't just a bad RAM stick. I hope it's not the slot(that's my only guess at this point), but I was wondering if anyone had any ideas as to what the problem could be?

and the CPU is an AMD Opteron 250, so PC3200 RAM should be supported.

... also, are you using registered (buffered) RAM ??   If you're not, that's the issue -- you need to use registered RAM modules.

Gary CaseRetiredCommented:
First, to answer your question:  NO!  Two sticks are not too much for the power supply.

Second, to help answer the question you didn't ask (e.g. "Why is it doing this?") -- does it boot okay with ONE stick of memory in the 2nd slot?

You're right, the RAM we purchased was not ECC. We are going to go ahead and purchase ECC-enabled RAM and hopefully, that should fix the problem.

It said in the manual that you must start with DIMM socket 1, so there's no real way to test the other slots.

Thank you for your help!

You don't have to use ECC memory -- but you DO have to use REGISTERED memory (also known as "buffered" modules).

... it is, however, a good idea to use ECC modules ==> just be sure they are REGISTERED ECC modules.
