What's the disadvantage of getting an Opteron server board?

[The Pentium Guy]

I'm kind of curious as to what the disadvantage is to getting an Opteron server board, such as Tyan Thunder, which will have support for 2 CPUs.

I mean these boards have pci-express slots, so you could definately put in a 6800GT or something. I doublt SLi support would be there. Woudln't these boards be more 'stable' as they're server boards?

The obvious disadvantage is definately lack of overclocking features. Fine. That's a gimmick. I'm just curious as to what else is the difference.

unless the software is compatable with dual cpu's it wont work that well, you will need ECC registered memory and also you might need a bigger case as some boards are eATX

One of the disadvantages of a dual opteron motherboard is the cost of the cpus, The ram and having a good enough power supply, I should know as I have all that in My PC zoom3 which runs 24/7 in an overclocked state with no problems.

Eek. Expensive. Very expensive. I'm assuming you won't get great speed in games anyways, as it's not meant for games.

You're going to leave the toy store and enter the serious arena.

This means: You need another kind of power supply, a bigger case, registered DIMMs (with or without ECC), and then you get to use your Opteron processors.

In return you get a much more robust RAM system, twin PCIE 16x slots (yes twin 16x), drastically improved I/O throughput thanks to the separate PCI-X busses just waiting for you to plug a SCSI RAID card in, the gigabit ethernet not connecting to the lame legacy PCI bus, etc. etc.

Yes that'll cost. But it'll show too.

I don't know as I play games on Mine and It does pretty good, Mind You that is while crunching numbers for Seti and this is at 100% load too.

That is 3 PCs, All networked, If You're just talking about zoom3, Thanks. But thanks no matter what. 🙂

Pretty cool stuff. Thanks for the knowledge bit

Actually ECC is required and isn't optional, If You do buy a dual opteron cpu motherboard, Spare Yourself a hassle with the ram and the psu, Get what I have, It's good stuff and It likes Opterons.

 

[Peter]

ECC is NOT required, the Opteron can run the memory controller w/o ECC just as well. Registered in turn is required.

In reality though, you'll be hard pressed to find a DIMM that is Registered but non-ECC, so you'll end up with Registered ECC anyway. Furthermore, with large amounts of RAM, you absolutely want ECC to cover up for the occasional "soft error". These do occur, one reason being neutrino particles passing through the material - yes even on ground level.

Well I was under the impression that ECC was required, Oh well. But of course having It doesn't hurt though.

Hey Zoom, joined up with Anandtech I see. I got a vacation from MSI forums for taking on the mindless Kilowatt Power Supply Cult (again).

You should stay here, far more likely to receive accurate information and at least they don't silence dissent or debate here.

That's the problem with Me, I used to be registered here, I think, But I guess I didn't visit enough and so well I guess It got deleted maybe. That and I cover at least a dozen or so forums on the web. pcper, 2cpu, anandtech, bbr, msi, elite bastards, cluboc, hardocp, systemcooling, ninjalane, amdzone, full metal alchemist, poke mon, xtremesystems, etc, etc, etc.....
