So what is it for?

Plan on doing some hard core CUDA computing?

My favorite part is how wussy Shadow's computer is by comparison. Guess he is gonna have to upgrade sooner than expected.

just my gaming rig and will do some work on it

What are you going to be using for rads on that loop? Which pump? Did you plumb those cards in parallel?

Rads (picture is from before I replaced the ASUS Rampage IV Extreme with the EVGA SR-X):



Dual D5 pumps installed in a prototype Monsoon reservoir housing. The cards are parallel.

Nice setup Darth! I like how clean and non colorful it is. (Still has nice accents with the blue on the fans, and a few other details)

[nycdarkness]

caselabs cases good stuff. Would love to get one but where to place it around my desk would be a new challenge

Err not really, since the current Xeon versions for socket 2011 have a locked multiplier, so you only bit of overclocking is done with the motherboard itself, wich according to several who've tried it over at EVGA forums, is only good for 105mhz BCLK(stock is 100)....So you get an extra 5% from it with any sort of stability.


Second, he's using E-2650's:

8 core chips, but running at a 2 ghz base clock, and 2.8 Ghz in turbo mode when not all the cores are being used, while in my case my pair of 6 core chips are running at 4 Ghz 24/7 for over 18 months now....Guess who's faster overall?...


Had Intel released xeon chips with unlocked multipliers, it would have been a game changer for sure, so why the use of water cooling the CPU's when they can't be overclocked anyhow?....

Wouldn't it be better for the fans on the two bottom radiators to all blow in the same direction? Seems like they would be fighting each other with the way you have it setup.

Impressive system Darth.

when your already watercooling 4 680's why would you not watercool the cpus?

Yeah, but in that direction you would have the heat that was just blown off the first rad blowing right through the second.

[Greasy]

Very nice setup Darth.

These are not retail chips (remember I work as a contractor/consultant for the large players in this industry)

2650's normally run stock at 2GHz but these are ES chips that have a stock multi of 23 and max multi i believe of 26 all 8 cores and 16 threads will operate at the max multi.

Retail chips are limited and will only clock a few of the cores to max multi

My buddy Travis, who I work with at ASUS and also on our own ventures, is a world record over-clocker Yeah, I think we have this covered.

[DarthBeavis]

about the fan direction on the radiators, I am thinking about using a design I came up with a few years ago to prevent the radiators fans from fighting each-other. I would make a baffle between the rads. I will probably have to make a new bottom plate for the case out of modders mesh so the air can escape.



For the tubing, I was going to bend copper hardlines and then nickle-plate them but too many people have been doing this so instead I have ordered some 12mm OD acrylic hard tubes (like in the Bitspower Crystal link kits). My plan is to use my heat-bending skills to do some really neat things (another guy has done this type of tubing but I plan to take it to the next level - we will see if I am successful).

[Nunz]

Shadow I would put demo's rig against yours in games. Guess who's faster overall bro!?

I am not familiar with a huge drama/derailment . . is this one of those cases where someone says they have this and that and then have nothing to back it up?

Once a guy at NVNews said the same thing about Skulltrails when I had a Skulltrail build and he posted a pic of the rig. Well, that rig was actually owned by Intel. I took a pic next to that rig at a LAN party at an Intel Campus and posted it so show the guy was full of carp that was priceless. oh Bigman, how we miss you.

anyways, if shadow001 has a better rig then I say great. this is not a competition. the more awesome rigs the better. anytime someone builds something or does a mod that blows me out of the water, I actually am elevated as I am considered one of the old school modders - having mentored many other modders who now are extremely successful. Elevating the hobby and building community to me is more important than individual glory and is what defines the work I have done.

[V2-V3]

Impressive setup DB!

16 Cores 32 threads of dewm Liquid cooled With a little tuning I would expect a ball park of 3GHz possible. Disable some C-states/Current limitations & lock those 2650s to the max 28 multi on cores, and a little more tweaking with upwards of 108~110BCLK can get you over 3GHz.

[slaWter]

24 terabytes in Will be installing a couple Intel Xeon E5-2650 processors,

I love the way the disks are installed! Plus amazing hardware all around.
I would love your setups even more if it weren't for those external case designs/paint jobs

Indeed. And very annoying as well.

Man that's ironic

[nycdarkness]

"Conduit" there I said it.

[shadow001]

when your already watercooling 4 680's why would you not watercool the cpus?

I guess for the visual aspect above all else, and yes the system is looking very cool.

Agreed. Total tool comment which was unnecessary.

Wasn't even me that started keep that in mind....Look to Aviphysics for lighting the fuse so to speak.

So you might get them to just under 3 Ghz with a max multipier of 26 at 100% load, and with some motherboard overclocking thown in.....It's basically the stock speed of the E5-2687W's but they cost 1800$ a pop in my neck of the woods, and the guys over at EVGA managed to get those to 3.5 Ghz relatively stable.

The chips are fundamentally the same as the desktop versions, except that 2 cores and 1 QPI link are disabled in the desktop parts to make sure those aren't used in 2 socket motherboards, and they can easily exceed 4.5 Ghz on overclocks with their unlocked multipliers, wich all Xeons are locked.

Shadow I would put demo's rig against yours in games. Guess who's faster overall bro!?

He'd be missing the extra 2 monitors and the 4th video card, so it depends on the settings don't you think?....

Sorry about your penis.

[Redeemed]

Not gonna' lie man- you got some nice hardware but I've never liked those box-style cases, just looks dumb in my opinion. Furthermore, all those different face plates on the front of the case makes it look even worse.

Great hardware though, not sure what that computer couldn't do.

True, i could make it more presentable at least with the fan controlers, but it means ditching stuff i already owned just because they look different, wich is kinda silly if they work fine.

Edit: Oh the box style, is pretty much a requirement when packing 5 radiators, 2 oversized 1200 watt power supplies and 5 water pumps with 16 fans in total....I.E, it takes up a lot of room....

[aviphysics]

Wasn't even me that started keep that in mind....Look to Aviphysics for lighting the fuse so to speak.

I just gave a little friendly jab to the ant hill. I am not the one that kicked it over.

The two systems just beg comparison, being that they are both over the top water cooled dual socket multi GPU mammoths.

Oh I know and understand that. Still don't like it.

Just means I'll never have such a system is all, even if I could afford it.

[aviphysics]

Yeah, but in that direction you would have the heat that was just blown off the first rad blowing right through the second.

The way I look at it is that your airflow should be high enough so that the air does not undergo a signifigant temperature change durring its path through the radiators. This would at least be the ideal for optimal cooling.

You can optimize under non ideal conditions by putting the radiators in series and blowing the cool air through the second radiator in the series first. This maximizes heat flux by maximizing the mean temperature differential betwen the air and radiator. I believe you would also want the radiators configured so that the coolest part of the second radiator is in front of the coolest part of the first radiator. I hope that was clear enough. If not, you can just google counter current cooling which is basically what I am talking about.

The symmetry of the problem suggests to me that putting a divider between them wouldn't really help. You would still have a pressure build up between the fan and the divider that would be aproximately equivalent to the effect of the fans fighting eachother.

What might be more help is removing the middle puller fans. This would make more room for air to flow between the radiators. Fans are much better at pushing than pulling anyway so it doesn't seem like the puller fans would be that helpful. You basically never see a puller fan on commercial hardware and I think you would see it at least sometimes, if it offered a signifigant benefit.

All that said... it may not be to much of a problem in the first place, thus the question mark in my post. It is just a question of whether the gap is big enough and how well the fans can tollerate the pressure build up.

My intuition on the matter comes from several years working a large water cooling system for General Atomic's DIII-D experimental fusion reactor. I haven't done any of the math on this one so as I said, it might not make much of a difference.

[shadow001]

Well, he'll have the ability to handle 32 threads in total, as he's got 16 physical cores and hyperthreading will be enabled, not to mention the fact that his processors are better IPC wise so that should add another 20% extra performance....My setup on the other hand, has 12 physical cores and handles 24 threads, they are older CPU's that aren't as good in terms of IPC, but are running at 4 Ghz constant, and 4.3 Ghz with turbo mode when not all cores are being used.

I'm guessing it'll be a tight fight overall....Better IPC with newer processors having more cores and threads on his setup, versus older processors with fewer cores but running at much higher clock speeds.

Oh I know and understand that. Still don't like it.

Just means I'll never have such a system is all, even if I could afford it.

SR-2 motherboards are now cheaper than they used to be, and the Xeon chips they use are sometimes on special....The last i saw were X5680's wich can easily overclock to 4.5 Ghz, on special for 750$ and these are processors that cost 1500$+ when they launched, and they're basically clearing socket 1366 inventory now that the E5 series for socket 2011 xeon's are available for the last few months, and so is the EVGA SR-X motherboard on the market, but Asus also makes one too that has overclocking capabilities too.


Anyhow, if it wasn't for the fact that Intel launched these chips with completely locked multipliers, i'd be all over it for sure, and i might still go for the SR-X motherboard but only when Intel releases the ivy bridge based Xeon's, wich it seems that they'll have a full 12 cores in each processor( for the high end models), so a pair of those totals 24 cores and handles 48 threads.

Even if intel pulls the locked multiplier trick a second time, going from a setup with 12 cores and handling 24 threads, to one with 24 cores and handling 48 threads will be an obvious upgrade, even if the chips are running in the low 3 Ghz range.

Now if we jumped into the way back machine I believe we would find that you justified the extravagance of your machine with the argument that it would take a very long time for even normal high end systems to match it and therefore require an upgrade to run games at max settings.

It would seem that performing a major upgrade in the near future would mean all the people that called your system a ridiculous e-peen enhancement were right.

The temptation to upgrade so soon when you claimed your system would last for so long is exactly what I was poking a little fun at.

You'd be absolutely correct in that assesment that i did say that, but this is in the context of going beyond gaming environments and offering enough performance boost over what i currently have already....I gave up on game developers ever going beyond 4 cores unless the next generation of consoles have more than 4 cores.

The other issue is the price of the upgrade, as the very highest end Xeon's for 2 socket motherboards are close to 2000$ a piece when they first launch, and i'm sure that the ivy bridge Xeon's will be priced that way....Add the SR-X motherboard to the shopping list and with taxes and shipping costs, i'll be looking at 5000$ easy, even if i can reuse the case and all the cooling gear(except for the CPU water blocks of course)....

Suffice to say that i won't be happy if the performance increase was only marginal( say 15~20% faster). for the amount of money involved in the upgrade, and i am putting it mildly...

[DarthBeavis]

shadow001 I will give you credit for packing in a ton of stuff into a small space, not easy to do

I am curious about how you are getting airflow to the mobo especially the ram.

Since I am an NVIDIA guy, I operate on the paradigm of GPU > CPU.

Not sure why you have five pumps. Two D5s with everything (parallel GPUS but still in series with rest of blocks and rads) in series is just fine. At least this is my experience . . .I think I have build most H20 systems than most people so I have a ton of experience and have tried all sorts of loops.

[BababooeyHTJ]

The thing that I find funny about shadow's rig is that its loaded with overkill like the five D5 pumps but then he goes and fills the case with a bunch of $5 sleeve bearing fans.

I'm having trouble keeping my three 7950s under 50c with the fans spinning nice and slowly. I can understand the need for so much rad space for four 7970s.

Enthusiast who they sometimes pay to do special projects (1099 contractor). I DO NOT work for them inhouse at all (though I would jump at the chance if ever offered).

The context of this thread is enthusiast as I truely believe the paradigm versus being a paid shill.
