Hydra/Hydro

BaBa · 12 Jan 2011 at 22:02

Ok my main folding rig (Hydra) is running HOT and LOUD ive even had a couple of hangs/crashes, not good.

So new cooling needed, but as its a quad G34 rig coolers aint easy to come by.

Noctua do a 90 and 120mm cooler for G34, they seen ok but with 4 in one box the case will need to be the size of Birmingham and have 500 other fans feeding it :mad:

Now to the point, i think water is the order of the day :eek:

Last time i water cooled a rig it was my PII 400 and i had to make the block myself at work

Blocks with G34 fittings also few, Koolance CPU-360 fits but its £80 a throw.
The block im thinking of is Aquacomputer cuplex kryos at £35(any good?)

What i really need to know is how many loops, what pumps (MCP655?) and will two 120.3 rads be enough.

CPUs are 140W max and no GPU's

Thanks

Many thanks Mr Biffa.

Thats kind of what i hoped as i cant overclock and wanted to keep it simple

Edit: Thanks Frozennova

Im down in Derby, many thanks for the offer of help i may well be needing it

BaBa · 12 Jan 2011 at 22:27

Yes i did see that but only after the post :rolleyes:

BaBa · 12 Jan 2011 at 22:36

I do like the idea of the sterling silver version of this block but not the price :eek:

BaBa · 12 Jan 2011 at 23:18

Will do ,it might be a while before i get the bits together.

Ive also got to move it out of the stacker 810 its in, just no room.

I have an old codegen S201 case that was my server, it will need a lot of work but could work well as its double width.
Water pump, rads and psu one side and motherboard on the other is the plan.

BaBa · 13 Jan 2011 at 00:00

Its in a stacker 810 as i read on another forum that the H8QGi-f fitted without mods into this case, this turned out not to be the errr.....case :mad:

I will post a few pics in the morning.

Is that a single 140x4 Mr Biffa?

I was thinking of two 120x3's with one after the first pair of processors.

I will have to measure up the case see what will fit then work round that. 14's might be a tight fit.

Actually just measured the pc in front of me and the drive bays are 14+ so should work.

Just come across a ToxicTBag2 in my boinc travels is this you MrT?

BaBa · 14 Jan 2011 at 18:35

Here ya go some pic's of Hydra

Pre install

Thrown together, note the coolers overhang the first memory slot on each bank

Couldn't resist

Sorry about the size of the pics they are from a while ago when i first set her up.

Regarding power it has 4 connectors three under the yellow tags, had to get pcie to atx converter cables to power the thing up or it trips the overcurrent on the Hx1000 psu :eek:

32GB was the easy way to get quad channel per cpu and if i ever run einstein on it that uses about 250mb per instance :cool:

Cpu's are opteron 6176se 12 core at 2.3ghz thats 48 cores of folding goodness, on the current workunit ( 6900 bigadv ) thats 09.03 frame time and 224500ppd according to HFM.

Mr Biffa may know better but its the fastest ive seen on bigadv

I realy hope Bulldozer turns out to be kickass as the 16 core opteron version should drop into this with only a bios upgrade

BaBa · 15 Jan 2011 at 01:22

I would think its pulling 650w or close to, maybe a little more.

BaBa · 19 Jan 2011 at 04:02

Pulled the trigger on the water the other day after getting her running stable with a desk fan blowing into the case

Should arrive today, hope I didn't miss anything in the order :confused:

Not as cheap as i had hoped but then quad sockets never going to be cheap

BaBa · 5 Mar 2011 at 17:27

First look at the build

Just tryin to work out how it all goes togther :confused:

BaBa · 5 Mar 2011 at 17:51

32 Gig of ram, its in an old Codegen S-201 that was my server for several years.

Ive modified the case extensively to take two rads a 420 and 280, made a custom tray to take this board and lots of other bits and bobs

BaBa · 5 Mar 2011 at 19:50

Now that would be telling

Actually not a lot tonight I should be working but my car has died

Edit: You might be right about the kink Mr Dekez but its just a test build at the mo I need some more fittings to complete it.

I think i will be swaping the pipes on the rad you can see in the photo just to get the run better.

BaBa · 5 Mar 2011 at 20:13

She's not up and running yet I still have some fittings to come and some work to do on the routing.

Biffa was saying that temps equalise over time but i put the smaller rad half way round the loop just to be sure.

BaBa · 10 Mar 2011 at 19:55

OK Hydra is now finally up and running (but not finished)

Still running windows for now and just picked up a 2684

after half an hour temps are 36c 36c 37c 38c across the sockets and no leaks

It was at around 68c on air, temps might rise with a better WU but not by much

I will be moving over to Linux probably tomorrow and probably Ubuntu as its the only distro ive used,this could be an adventure all on its own

BaBa · 10 Mar 2011 at 20:32

Yep thats at full load, temps off load all 25c

BaBa · 12 Mar 2011 at 20:10

Yes the cables are messy but its a work in progress.

What is the total "gigaflop-age" of this beast?

Each processor does about 110.4Gigaflops so about 441.6 is total

BaBa · 14 Mar 2011 at 14:00

Finally got another 6901 after lots of smp's and with NUMA on (node interleaving disabled) frame times have dropped below 6.30(just)

Thats a theoretical PPD of 370k :eek:

Ive also spotted some G34 engineering samples on the bay, these should have unlocked multipliers and would go well under Hydras new water
