nForce4 SLI / Dual Socket 940 / PCI-e and 64 bit PCI-X

Thought I would split this off from the last conversation and see what you guys think of this. This would do my Adaptec PCI-X 64bit scsi controller good.

My friend and I saw this board today. He was stuck with a FX-53 940 and was worried about no PCI-e. He doesn't have to worry anymore.

I'm not upgrading though until the dual core chips, but this is about the only PCI-e answer for the AMD Socket 940 FX-51 and 53 owners.

nForce4 SLI on a Dual Proc Opt 🙂

This thing is a monster and a sign of things to come. I could deffinatley distort this thing into an awesome gammer.

This thing rocks:

PCI-X and PCI-E

No PCI-X

Just starting my review of the specs. This system board is probably limited on Over Clocking features but probably can be manually manipulated.

It's mainly a Power Workstation for doing C.A.D. , etc..

But I would get this thing for a Power Gammer for sure.
 
I am a CAD user, but a cheapskate..Hence look at my vid card..I want to OC cheaper opteron chips....

The only reason xeons are even still remotely attractive to me for a dual setup...My cad apps love HT and thus 4 virtual cpus would do quite well...Xeons downfall is shared memory bus for the 2 cpus. BUt since I get get 2.4's or 2.66ghz 533fsb chips and clock them to 3.2-3.3ghz range for under 400 dollars that makes it impressive....

There is a nice abit mobo that is rumored to have some ocing (enthusiast style options) features...a couple of cheap 242's and clock them to 250 range would be worth my while...
 
Yeah, what gets me is the PCIe x4 connector with x2 bandwidth... hahaha. Should be OK for a x4 PCIe U320 controller. Each PCIe lane represents 320MBps of bandwidth.
 
I think I saw someone running one of these things yesterday.

Besides dual CPUs, it had 16GBs of RAM and dual 6800 Ultras. Before you claim the RAM was a waste of $, he said he used it for work. He uses extremely advanced medical programs for analyzing MRI and CT scans, which can "easily" consume 9GBs+ of memory.

Original link: Futuremark Forums...the link to the actual post has pictures, but those forums are currently closed for maintenance: Pics.

Insane stuff.
 
I read the whole thread about the guy with the 16gb of ram. He said they use 9GBS. Too bad he's running windows, which is just starting to be a 64-bit operating system. The most ram a 32-bit application can address is 4GB.

Most medical centers use clusters for MRI and CT with 4GB of ram per CPU. I totally believe the guy has that rig, but he is a dumbass. It would have been far more efficient per dollar to user a cluster.
 
One thing to maybe mention on the tyan:

last I checked, no one was quite sure if you still got 16x + 16x pci-e (or what would happen, exactly) using just one processor, since there was one nf4 paired with each cpu. some thought that one PCI-e and one GBe would be disabled, some said the second PCi-e would be 2x. might not be so good for skt940 FX users who want SLI

if this has been clarified please feel free to correct me.

edit: see block diagram on p2:

datasheet

second edit:

From the manual:

"In order to access PCI Express x16 slot 3 and second Nvidia MAC, TWO CPUs must be installed."

Correct. I noticed that in the manual too. Pci-e slots are full 16x.

Need 2 cpu's installed in order to use sli mode and 2nd nic. No biggie though.
 
You need two cpus two use access the second x16PCIe and NIC

Using 2 x16 PCIe isn't always SLi

Like when you have a 3DLabs Wildcat Realizm 800 for rendering and a X850 XT PE for game engine testing.
 
Does this mobo have a 1000HT ? The opteron 252's are 2.6ghz w/ 1000ht..

Anyone have this mobo yet ?

Jose
 
My board only supports 800Mhz, but it's an engineering sample. I've emailed them about it and will post thier response.

I didn't get a direct response from the engineers to explain your question but they did instruction the web folks to update the spec sheet to show 8.0GB transfers. So to answer your question I guess this motherboard will support that.

Dual-core CPU's are still an unknown since they have yet to be released to the partners to do evaluation/compatiblity testing. AMD is busy showing them off but the partners aren't getting them yet. We don't know when we will have an affirmative answer to this inquiry. When we do it will be put up on the website.

Uh, unless you have an application that supports PAE and you're running a Windows Server OS. Which I'm gonna have to assume he is if he's got an app using 9GB of RAM.

Possibly... depends on the apps you're running. Some computations are not easy to split up between multiple machines, since they depend on too much inter-processor communications.
 
The Tyan K8WE looks real nice. I plan on building a little server based on this mobo w/ RH ES 4.0 Linux.
I'm sure a pair of 246's w/ 4gigs of ram and 6 - 10k5 73g scsi hd's on a LSI 320 raid controller will fly.

The users will be coming from a dual 700mhz dell poweredge.. lol....

Can't wail till the database software is ported to RH4.0......

Try the tekram SIR-1220

PCI-e SATA II RAID (0,1,01,5,6 in hardware) with NCQ and very near SCSI Performance.

It's a little (well, very pricey) But if you need very many GiGs of storage then it evens up pretty quick
