Dual Quad Opty SLI Build (Tyan n6650w) - Overclock.net

Dracc · 07-12-08

I thought I would preface this post by telling you exactly what this computer is going to be used for so that I am not inundated with posts about my motherboard choice. This is not a gaming PC, though that will certainly be one of its functions. I work for a game developer, and do a lot of heavy crunching in my spare time, which might range from graphic to video editing, 3D rendering, or any number of other intense applications. I am also planning on using this system as a primary server on my home network where it might stream video to or debug XBOX 360s, XBOX 1s via XBMC, or host files for use on the other PCs around my house. Finally, as mentioned above, I will be gaming on this system as well. Certainly very few games will be able to take advantage of all of its processing power, and I know that the chipsets are not amongst those which are ideally suited to gaming, but I have a feeling that raw power should suffice for most games. With that out of the way I would like to introduce my Dual Quadcore Opteron SLI Build. I haven't settled on a name yet, so brownie points to anyone who can come up with a decent idea for one. (hint: My desktop at work is called Cerberus, inspired by its triheaded video display, and my laptop is Orthus, his little brother)

Parts list:
Motherboard = Tyan Thunder n6650w(S2915A2NRF)
Processor = AMD Opteron 2352 x2
CPU Cooler = Noctua NH-U12P + Socket F adapter x2
Memory = 8GB of Kingston 240-Pin DDR2 SDRAM ECC Registered DDR2 800
Graphics Card = EVGA 8800GT SSC x2
Case = Custom X-Clio a380BK
Case Fans = Noctua NF-P12-1300
PSU = Corsair HX1000W
Other parts = Cheapo SATA DVDRW, some fan silencers and a grill from Xoxide, thermal compound, HDDs scavanged from around the office and home(Untill I get some Raptors to RAID).

All parts have been ordered, and are on their way. I will try and price out all parts at retail value to give you an idea of its actual value. I have assembled what has already arrived at home and grabbed some quick pics(That is right, no smoke and mirrors here, I'm all legit).

The mobo, with all the cables I might ever need supplied. How nice of Tyan!

The back of the mobo. I dig the S/PDIF on what is supposed to be a server/workstation board

The SSCs. An ebay purchase, so I was glad to find out they work 100% and look shiny too.(note the reflection of the box on the card)

A close up of one of the SSCs. (BTW, these benchmark almost exactly the same as the XFX 8800GT Alpha Dog XXX at stock speeds)

The case. Lots of room for the EATX mobo.

The second 250mm fan, and also the unmistakable silhouette.

Top of the a380 for reference. The flash really greys out the plastic.

And here is the custom part of the case.
I will be installing a second 120mm exhaust right about where the grill is sitting. The grill should look stock(color difference is due to flash) when it is installed on the inside. I am going to epoxy the grill and fan into place so there are no screw heads on top of the case. The hole will be laser cut. Fingers crossed that the local sign shop doesn't mangle my case.

Well there it is. I have to update the BIOS on the mobo before my processors arrive. Turns out the board requires an updated bios to use the quad cores. Luckily I built a friend of mine a similar system on the Tyan n3600b mobo a few months ago, and I can 'borrow' one of his dual core CPUs long enough to get the BIOS installed.

Please leave your comments below! I would love to hear what you think. Also, I will update this as the parts of arrive and get benches up as soon as it is assembled and the HDD is built.

Special thanks to shinji2k for clarifying the PSU compatibility and suggesting a fairly priced 1000w unit.
Also, thanks to all the trustworthy eBayers who made this possible, as well as the retailers found in my product links

looks pretty sweet. One thing i noticed, is it looks like theres 8 dimm slots. so if you wanted, you could put up another 8 gigs of RAM in there correct? Also, i am assuming u r running vista 64-bit correct? i suck with names but ill throw a few out there. So since this sounds/looks like a beast of a system, ill throw out Ultimus. nice build man.

That case is beautiful...

Server board with PCI-E x16 x2?

~B~

SerenityKill3r · 07-14-08

This system will rock

OptyOctoCore FTW!!!

Rep+ for you my friend

SkoalFineCut · 07-14-08

Very nice.

If you only had 4 quads you could name it 442, after Oldsmobile's musclecar of the late 60s/early 70s.

Comp112 · 07-14-08

I vote for...Hercules.

And man, if I had allot of money, this is one thing I would build.

ChrisB17 · 07-14-08

Wow very very nice.

Thanks so much for feedback and the rep! I've noted the name suggestions! Some of my coworkers have suggested a few other names as well, notably Charybdis and Orpheus. I'm still undecided... I just might have to wait until it is finished before I really get a feel for it and then decide.

Answers to questions:
Main OS will be Vista Ultimate(I can buy from the MS store, so that will be cheap), secondary OS will be XP Pro for compatibility with some of the software I have to use that isn't currently running on Vista. Also, I think some of the *nix OSes might get the most benefit out of the hardware, so I will install one or two of those as well. One of my coworkers mentioned that kernel compiles should be interesting to see, and I believe that *nix massive computing projects have more efficient use of the hardware vs. their Windows based counterparts. Plus, I need to learn *nix better anyway.

Yes, it can take up to 16GB of ram... but I couldn't justify the expense right now. Also, I am using all single gig sticks which will give me the maximum amount of bus bandwidth. Another note is that each processor may only access the ram on its own bus, so each processor only has 4GB of ram to play with. This is especially important in single threaded apps. Even 4GBs should be enough for any single threaded app though

Yeah, those are PCI-E 16x slots on the inside. The ones on the outside are only 8x though. Unfortunately if I use the 16x slots the heatsinks will be blocking all but one PCI slot. (Note the bottom two white slots are PCI-X slots, which were intended to replace PCI prior to the advent of PCI-E. the PCI-X slots will run PCI devices though.) I am certainly planning to use the 16x slots, so I have to decide between getting an audio card, or a capture card. I was thinking of getting an onboard audio card and finding an external capture option.

Tyan does make a quad quadcore board, but sadly no SLI support

Update: PSU arrived today. Now I can finalize the placement of the top exhaust fan and get the case cut. I called the sign shop I had in mind to do the cutting and they said they use a plasma cutter and that it could only cut something that was flat. So, they're out. I might use a radial router because I have picked up some vinyl stripping from an autoparts store today(6' for 65 cents) that will cover the edges so if it isn't perfectly smooth, or if the paint chips a bit you won't be able to tell. Also, it keeps the edges safe. I'll wait to get more pics until the rest of the parts arrive this week.

Please feel free to ask any questions, as there are a lot of peculiarities to this build, and I would love to talk about it amongst other enthusiasts. Keep checking back!
