Welcome to the Budget BOINC Server Club (BBSC) 

 

This is the place to show off your handy work building a budget minded multi-CPU BOINC cruncher. 

 

Discuss building or buying cheap server based BOINC crunchers, and provide or request assistance from fellow BOINCers. 

 

Validate your proposed configuration before pulling trigger.

 

Discuss configuring and optimizing the performance of these systems. 

 

If you have a lead on some good cheap pieces, post it here.

 

For starters if you already have a system to display post a reply with the following:

 

Motherboard:

CPU(s):

Memory:

GPU(s):

PSU:

Storage:

Case:

Cooling:

Operating System:

Manufacturer for pre-built systems

Approximate cost:

 

PICS PICS PICS!!!!
 
British Bob suggested we get something like this going, if you have any ideas how to improve the content to make it more useful, let me know.  Meantime lets see those servers!

Here is the one I have documented in another thread, still waiting on a proper cooling solution, and at some point I'll likely want to get it off this piece of plywood.

 

Motherboard: SuperMicro X8DTT-F-SG007 Rev.2

CPU(s): 2 x Intel L5640 (6 core with HT)

Memory: 6 x 4G Micron MT18JSF51272AZ-1G4D1ZG 

PSU: AHW5DC252W SGI Switching Power Supply

Storage: 500G Seagate 2.5" HDD

Case: NA, 17x11 piece of plywood

Cooling: work in progress, probably factory heat sinks and some 92mm fans

Operating System: Linux Lint 17.3

Approximate cost: $240 for the motherboard, CPUs, power supply and memory.  The rest I had on hand.

I'm curious about this as I might be tempted to set one up for various BOINC projects myself ^_^

BritishBob 04-10-2016 01:13 PM

Motherboard: Supermicro H8QM8
CPU(s): 4 AMD 8439 SE
Memory: 16GB DDR2 EEC 800Mhz or 32GB DDR2 ECC 667MHz
GPU(s): None currently
PSU: 650w Supermicro PSU. Looking to repleace at some point.
Storage: 1TB WD Green
Case: None
Cooling: Heavy copper heatsinks with 3000rpm fans.
Operating System: Linux or Windows Server Datacenter
Approximate cost: Base $350 with shipping from US to UK.

$400 with 32GB ram as it sits

Edit:

I acquired 64Gb of RAM. Turns out one of the memory slots is dead, so I have just 60GB RAM. :'( Total cost £70.

Total Build cost with 60GB Ram, $500.

SuperMicro H8DGU-F $75
EVGA 430 Watt PS $45
2x Opteron 6276 $80
2x Modified CM 212 Cooler $50
16 GB memory laying around
120 GB SSD laying around

Total $250

The proper heat sinks showed up and I strapped a couple of those micro fans from the stock AMD CPU heat sinks on them.  Running 24 NFS tasks now and getting 55 - 59C readings on CPU 0 cores and 61 - 65C readings on CPU 1, I assume a 6C difference in the 2 CPUs is normal enough, temps seem quite good overall. 

 

Do you typically run one task per thread?  Or do you leave a thread or two free for overhead?  Looking in TOP my load average is 25.06 where 24 would be 100%.

If there are no GPUs, then 1 task per thread.

I have to say, that's downright gorgeous. So tempting to pick up two of those boards, the slightly more powerful power supplies (the SGI AHF5DC456W ones that offer 476 watts of power, instead of the AHW5DC252W which apparently only offer 264.5 watts) so I have the option of going with X56xx processors in at least one of them, and then figure out an enclosure later....

I think that's the one Tex uses, its a little cheaper with shipping than the smaller one too, but you would have to rewire the connectors unless you can find one set up correctly.
