Summermute: a 4p server for folding, storage, & hosting

I didn't get a lot of money when my dad died of a rare, poorly-understood disease...but after funding the rest of my schooling and living expenses, I had about enough for new system.

Right about the time I was ready to spend some money on a folding system, Desert Rat posted an insane deal on 4 Opterons, and, well...here're the results in a build log:

Receiving the first two Opteron 6134s:

450

and

450

I then had a few weeks wait as I ordered the rest of the parts & coordinated shipping. Then, the motherboard (the 4p monster, an H8QGi+-F) arrived...

450

Finally, the part I'd waited for the longest: the case. I didn't have many options on this, as very few cases accomodate SWTX (proprietary, bigger than HPTX)...but based on another 4p builder's recommendation, I contacted Chenming USA and procured this ~80lb behemoth:

700
and it's nifty modular fan cages:
700

Then...my phone lost all kinds of photos mysteriously, including the RAM (4 kits of low latency 4x2gb from G.Skill), SSD, PSU, etc.

Somehow the most dramatic photo survived: the tiniest of wounds during building.

700

I ran Summermute - so named because the roommate's HTPC I built had been christened Wintermute (we'd just finished reading Neuromancer) - for a few days on SMP folding for test runs, and then switched it over to its first -bigadv for the Chimp Challenge!

Folding away for OCN [and the CC as of May]:
700700700

I didn't have many difficulties (save for picking the beast up). The only really notable failure was that of the onboard graphics (wouldn't work on either of two monitors), and that only sacrificed a spare, cheap GPU I had in a previous build.

Future plans:

- Move it to somewhere more out of the way and where its noise won't be quite as bothersome
wink.gif

- Overclock it, and finish tweaking the [email protected] utilities (e.g. Kraken, etc.)
- Learn Ubuntu a bit more so I can fulfill all of its potential (incl. VPN between Summermute and friend's Wintermute)

...phew, first build log! I likely won't update this with much more, as grad school takes up almost all of my time, but suggestions & comments are welcome!

-- ps: Thanks to Desert Rat, derickwm, and zodac for all the help & guides!

The underlined in his post shows why he had to sacrifice a graphics card solution for it.

If you're going to quote a post full of pictures, use the spoiler tag.

But surely, there is no need for a discrete GPU, it's an onboard on that mobo right?
Ahaha, you know it's a serious case when it comes with wheels - and this one actually needs 'em! Phew.

Great question! Yeah, unfortunately I was forced to use a discrete GPU (that prevents me from using another fan; argh) due to the onboard being DOA. Not a huge deal, as I had the card in another machine dedicated to folding *shrug*.

My rough guess for PPD is ~185k, I'd say. That's with a few conditions:
1) I calculated that figure very roughly (see point #3 for lack of HFM accuracy)
2) I've only had p8101 come to me so far, so, blegh to that.
3) Grad school's been really busy and I haven't had time to optimize the set up (e.g. Kraken or Langouste. I'm not at all proficient with linux so it takes me a while to get through the step-by-step instructions; I like it, I'm learning, but I barely have time enough for proper sleep)
4) It's been bloody hot here, so I haven't been overclocking [though I made sure to get a properly supported motherboard, so it's a future possibility]. I've been pretty worried about temps (hit 65C yesterday! Argh) on the CPU's as-is, so, no OC'ing for the next few months...

If I'm able to score either some free time with the beast or some nicer WU's, I expect that number to increase!

Very nice PPD! I'd love to see some more pictures if you have any. This build really intrigues me for some reason

Sure thing, I'd be happy to take some more photos! I'll have an hour or two free to work on it this weekend, hoping to flash tear's BIOS to it (I've heard it allows for greater RAM control) and take advantage of the slightly cooler temperatures lately to maybe throw Langouste into the mix. I'll get some more internal photos, too, as I'm opening it up to add a 2tb HDD for infrequent streaming purposes (might as well take the dedicated NAS offline if Summermute's online all the time anyway...)

Kazenagi's hot on my tail, so I've got to come up with 50k PPD somewhere!

Heh, yeah, sorry they're a bit late: having trouble with grad school (nearly failing one class), science is hard ;p

Here ya go! The previous shots really didn't show the other recess - HDD bays, really, but just as ventilated as the MB tray - so I wanted to show the width (via frontal shot) and an inside shot. Really, my plan - in a few years and more money/time - is to fit another full system in here...

(there're holes, and even space/bracket for another ATX PSU!)

PS: PPD went up significantly since installing the Kraken, huzzah! Didn't take too much time at all. I'm trying some 690x to see how they do... (been getting only 8101 this whole time)

While I wait on some more (smaller) fans, here's a poor photo of my poor setup. I'm excited to get some faster, higher power fans in there so I can begin OC'ing (weather's finally starting to cool off).

Note the angled 120mm's in the front modular fan bay, and the twist-tied-on BitFenix....*sigh* It's temporary, promise.

Okay, other fans arrived! Now I can replace the stock fans with same-size (92mm) using the native, modular fan cages...but these blow a lot more air. The two delta fans in the front will help blow through the first two heatsinks as well as move more air around the case.

I was also able to add a small fan to the rear of the case, to help out the fan-deficient HSF (because of necessary GPU; see OP). I saw immediate, collateral results: the small mobo heatsink directly in front of it went from blisteringly-hot to cool. Sweet!




I can also, incidentally, replace some of the HSFs, from the Noctuas I have. This brought me some trouble -- I got a much more powerful fan (12W, 38mm thick). I plugged it in to see if it functioned...and it flew violently at me. So, any mounting solution had to be pretty bulletproof...

I initially tried using a shroud on the intake of it, and mounting it between heatsink 3 and 4. The shroud for intake didn't work, unfortunately, as the retention clips weren't sized for that. I then tried [successfully] mounting the shroud at the exhaust...but the Tornado didn't pull in as much air as I'd hoped, leaving heatsink 3 too hot.

So, at risk of burning them both out, I placed the Noctua as pull on heatsink 3, and left the Tornado as push (with shroud, for retention clip usage). I felt like returning the other noctua to pull on HSF 4 might be a poor choice, adding to the burning-out...but...unsure.

I foolishly tried moving a fan while Summermute was on (hey, gotta fold them proteins...) and this flew at my face.

Lesson learned, Tornado.
(and yes, now it's unbalanced as hell and vibrates menacingly. I...refuse to try gluing it back on, so if it ends up being a problem, it'll have to wait until next loan disbursement.
wink.gif
)

And, this is the final product! Added a rear case fan, replaced one front case fan, replaced two HSF with one 38mm, minor cleaning. The BitFenix 200mm fan won't be there for long, as I'll be replacing the side panel when I move the server (to the window, I think: it'll be louder, but cooler; who needs quiet when studying? The screams of pathogens should drown out any loud deltas anyway)



Non-ideal situation at the rear two heatsinks, but...I'm out of ideas and both heatsinks are now finally only warm to the touch (versus very hot), which is

in my book.

All of this thermal stuff means...OC'ing time!

Finally took the dive and began OC'ing Summermute. I had some initial difficulties, and it doesn't OC too far, but I was able to speed up over a minute per frame on p8101. That may not seem like much, but, any little bit helps

.

I was aiming for 220, which dropped two WU's (including my first p8102 on this passkey...doh!), so I'm running it at 215 currently (this comes out to ~2.47GHz over 32 cores). I didn't have enough time to push it past 215, or to try and diagnose what caused the instability (RAM?) Temps didn't increase by much (1-2 C). I'm hoping for 220k PPD with this on p8101's now.

If anyone would like any help overclocking, refer to this awesome thread at [H]. It took me a while (linux noob) to figure out flashing tear's BIOS and OC'ing, but I'd be happy to help anyone if I can. There are many here at OCN who've also OC'd their G34 rigs
