EVGA SR2-It is here and OH MY GOD is it a thing of beauty!

I picked up 3 cheap 280GTX's the other day to run on one of these boards for gaming as well as GPU grid. I was thinking about putting the GPU's under water because I see a few people complain about high temperatures causing damage over long periods of time. But getting a set of new blocks for three cards seems to be almost what I paid for the GPU's themselves so I'm wondering if it's worth bothering to watercool them at all because with that money I could get better CPU's.

Would three GTX 280's be fine on stock air cooling?

Run them on air for now. Soon GTX 470 & 480 will be out (hopefully ). Then look for blocks that doesn't fit on new cards, and hopefully you can get 3 of them for the price of one, then.

Neeeeed X5650 for cheap... please be 800 when you hit newegg... pleaseeeee. lol

Anyone think you could fit two NH-D14's on here? If not I think I would go for dual Megahalems or maybe Venomous X (not a fan of its mounting system tho).

[jcool]

Nice rig jcool. Got an idea of the build cost on that beast?

Regards,
Bob

Well.. retail build cost would be something like 1600$ for the chips, 250$ for the board, and maybe another 300 for ram, PSU and coolers.

Kinda steep I'm afraid...

This is the machine on BOINC btw

I'm guessing that output is with stock clocks?

I apologize if i've missed something posted already in this thread regarding the use of this board in the enthusiast (OTT)3D modeling / rendering community, but this is exactly the type of hardware I've been waiting for!

Most software renderers, mental ray, Vray, FinalRender, Maxwell, Indigo, etc., are CPU bound (press "render", sit and wait for hours) and can't make use of the power of one (or more) of the GPU's that are installed in a system requiring several computers networked together in which to "farm" out the renderings/animations to each systems' cpu's. This is obviously a hassle, buying and maintaining multiple systems, licenses, etc...

Now, there are several real-time GPU (unbiased) renderers on the market that will make perfect use of this type of board loaded with GPU's that won't require a damn renderfarm. I will be looking into either building a machine with this mobo, or the ASUS P6T7 WS Supercomputer board and run Octane and Arion.

Needless to say, I'm very exited to see what kind of numbers this board can produce loaded up with several CUDA GPU's and 12-24gb's of ram.

Cool it properly and the power is there.
Think on this: At 4200mhz on air cooling I was not only matching but beating the fastest times on wPrime of machines pumped to 5600mhz cooled with LN2..
That should answer ALL your questions!

[LarsMarkelson]

Interesting... from the looks of this pic I think you could fit two NH-D14's on it.

But mounted in a case... that'd be a lot of weight. Hopefully it wouldn't break.

[INFRNL]

I know a single GTX275 is about 20k / day for me. 4*GTX295 = 8*GTX275 = 8*20k = 160k ppd? Rough estimate!

You should be able to get higher than 20k ppd on GTX 275 if you oc. I havent checked lately since the ACEMD, but I was avg over 20k+ppd before.

4*GTX295's do not equal 8*Gtx275's That would equal 8*GTX260's a GTX 296 is quite a bit off from 2 Gtx 275's if I remember correctly.

Holy crap, past couple days I have been getting 30-35k ppd on my 275's

GTX295 = GTX275 x 2 clocked a little lower.

Nice I just watched that Mountain Mods Extended Ascension video. Didn't realize the mobo lays flat inside that case... that's pretty awesome. I think I just found my case

[INFRNL]

Yes GTX 295 clocked lower(maybe inproper wording on my part). I do not recall if you are in the grid or F@H section, but I guarantee the GTX 295 will not produce as much as 2 GTX 275's...I will bet you lunch on it j/k
I will go hunting through past posts/threads to prove it.

I know that, the way you worded it implied that a GTX295 is a pair of GTX260's. Which it is not, is has the same memory bus and shaders as 275

I'm well aware of the F@H power of each Nvidia card, but a 295 takes up the same space as a 275

oh are we saying the same thing in a different way . That is very true that a GTX 295 takes up the same room as 1 GTX 275 and produces more.
I guess what I meant was that the actual production of a 295 is closer to that of 2 GTX 260's.

glad we could hug and make up . I am not very good with words

However I can clearly say that I want a W555 System

Yeah

Mostly I just like threadjacking Dave's threads as much as possible.

Maybe I need to find a brother for this X5677...

[=[PULSAR]=]

Hey Dave just wondering on how your temps were holding up running WCG? If you could I would love a screenshot using realtemp.

[Movieman]

Hey Dave just wondering on how your temps were holding up running WCG? If you could I would love a screenshot using realtemp.

Temps using realtemp:
3330mhz loaded: high 30's
3600mhz loaded: mid 40's
4000mhz loaded: mid 50's
4200mhz loaded: mid 60's
4400mhz loaded for fast SP1M run was 67C average
All on air with TRUE's with Delta 113cfm fans in a open case with room temps at app 70F

[jcool]

I'm guessing that output is with stock clocks?

Naturally. Can't be OCed on a Tyan (well, technically it can, up to 137Mhz BCLK)
Note that I am still runing 1x X5650 and 1x X5660 on the same board. CPUs average at 3,0Ghz (2,93 and 3,06 Turbo modes respectively).

Pretty good temps you have there. Have the same cooling setup on an 920 running WCG and temps are mid 70's @ 4ghz. Are those speeds with turbo on or off?

don't mean to be picky, yet the graphs shows 10k a day for dual 6/12 xeons?

havn't had the chance to check they're formulas yet, these BOINCstats seems to have a very strange way of calculating results

10k with stock 2.6ghz is right overclock to 4.2 like MM and you get 15k Hes my hero

Turbo off for all..Turbo is a nice boost for stock settings but when your up there, your up there and no need for it to be blunt.

1BOINC point=7 WCG points, so jcools 10K Boinc=70,000 WCG points per day

Awww golly Gee!

[Movieman]

double post!
4500 on air and EIGHTS!

that depends on the project and granted vs claimed credit!

anyhow ~50k+- was the predicted number, and that is MASSIVE

[Movieman]

all in WCG are pretty much granted the same, some small differences but not bad.
Confused on what you mean by the part I highlighted??

[onex]

a pentium dual core 2.0 would give ~2,600, nehalem's gives much higher per core,
generally, logical cores doesn't scale linearly as physical core should.
4+4 920, should score ~16,000, - triple that .

btw, seems the Xeons aren't optimized for Pi calculations,
4.5 920, gives a better score then a 12 core Xeon @~the same speed ,
and that's for 1 X5650
SuperPi - 9sec 0ms - Brolloks (OC Forums) - (Intel Xeon X5650 @4323MHz

seems like not all cores are being utilized.
