Upgrade Memory on Dell Precision 490 - Notching doesn't match?

heya,

We have a Dell Precision 490 workstation, in which we're trying to upgrade the memory.

I was under the impression this took DDR2 ECC fully-buffered sticks.

However, we obtained some RAM (http://www.memoryten.com/pc/006778/DDR2-240p-PC2-5300ER-2GB/, which I was told was ECC fully-buffered), and noticed that the notchings on this didn't quite match, which means we couldn't install it.

In the photograph, you can see the RAM currently in the server (top), and the RAM we tried to install (bottom).



Does anybody know what the mismatch here is please?

Thanks,
Victor

your pic link doesn't work

your computer supports
Up to 32GB quad-channel DDR2 Fully Buffered DIMM (FBD) 533MHz ECC memory; Eight DIMM slots
--1 The total amount of usable memory available will be less, depending on the actual system configuration. To utilize more than 4GB of memory requires a 64-bit OS. To expand memory to more than 32GB requires a Dell Precision
490 1KW system with memory risers. 2 Quad-channel memory requires 4 each of the same capacity memory DIMMs--

now if that all looks like gibberish to you, the site you went even lets you select your computer, at which point it tells you what ram is compatible as seen in this link
http://config.memoryten.net/Configurator.aspx?mfr=Dell&...

or if you do understand the specs above you can likely save money by ordering from newegg.com

heya,

Hmm, the link doesn't work? Weird. It displays fine on here, lol, but that may just be me.

I actually just uploaded it to my TwitPic (Twitter) account, you should be able to see it here:

And yeah, I did know it supported FB (or thought it did), however, I'd thought the new DIMM I had was FB as well?

Cheers,
Victor

heya,

Thanks for the reply.

So the issue is, the 490 needs fully-buffered, and the RAM we got wasn't fully-buffered.

Fair enough.

I based it off of here (http://www.memoryten.com/pc/006778/DDR2-240p-PC2-5300ER...), and the RAM being said to be RFB, which I assumed to be registered fully buffered.

Ah well, I guess I'll keep hunting for RAM then. All I need is DDR2 FB then.

Cheers,
Victor

victorhooi,

did you ever have luck buying finding your ram? I'm currently dealing with the same problem.

It seems ram for the 490 is VERY expensive!
