Mamajuanuk, Yep, will do, as soon as I get some stats going I'll post them and the power usage down to a PPWatt level.As you can see from my build I am a fan of the Opterons. Please let us know how it produces once you have a good 10+ days of run time in. FYI the 6274 is truly 16 cores per socket. There are no fake cores in the AMD world. Hyperthreading should be counterproductive in HPC applications. I also have the Noctua heatsinks, they are very good and quiet. Congratulations! I'm looking forward to it!

Mamajuanuk, FYI the 6274 is truly 16 cores per socket. There are no fake cores in the AMD world. Hyperthreading should be counterproductive in HPC applications. Not sure I agree with that statement. Interlagos and Bulldozer both share 1 Floating point unit between 2 Integer "cores". In my opinion that's basically the same as hyperthreading in the way that it makes "fake" cores by resource sharing. However, Magny Cours is 1 for 1, having full resources per core. That's why I went that direction with my build. If your crunching primarily depends on integer math computing its not a problem, but floating point intensive applications will suffer.

Am curious about a few things crunching with 54 threads. As mentioned I'll post some stats when it's up and running.1. Hard disk bottle neck. Will boinc keep everything in memory until written or page file it. 2. Memory. How much memory is needed if Boinc keeps it everything in ram. 3. Hard drive speed. Will a raptor hard drive be best? Ryan, do you install boinc on the OS drive but data on a second drive? Any raid? This system will most likely have 1 x 10k SAS drive as the OS and data drive. This works well for the 24 thread machine and that's running 1 x 10k raptor drive! As for RAM, the 24c machine has 32Gb but Ubuntu and Boinc only use about 3 Gb between them. I always have leave app in memory set and never use the cache option BTW - this build will be 64c, not as you mentioned 54c typo there I guess... Still we'll have to see once it's buiilt and crunching!

I'll also be very interested in seeing how this performs, in terms of power-usage, disk-access-limits, memory-usage, etc, as my planned build for some point in the next few months (have to have my boiler replaced at home, first) is very similar to yours: The fans make all the difference, as mentioned, I will not be using the Supermicro caseas the supplier let me down. I'll be building a custon open case for it. Similar to those listed in the link above.Chassis: 1U SC818ATQ+1400 Motherboard: Quad AMD Opteron 6000 H8QGI+-F CPU: 4 x AMD Opteron 6378 (16-core 2.4GHz) RAM: 16 * 4GB DDR3 PC3-12800 ECC/Registered RAID: LSi 9211-4i HBA SAS/SATA3 4-port HDD: 2 x 250GB WD VelociRaptor 10K-RPM SATA3 in RAID-1 setup PSU: 1400W 95% Efficiency Not sure what fans are in it, but it's a full server-build from http://www.rackservers.com , so I'm assuming they're not going to skimp out - will be discussing it with them before I order, anyway, so cooling won't be an issue. Stats data will be posted in due course...

Update component list to reflect recent arrivals... Looks like the build will start soon!

By the way, are you planning on running this at home, at work, or will it be hosted in a data-centre somewhere?
----------------------------------------I worked out mine could potentially pull just under 6A if the PSU managed to hit full-load, which could get massively expensive on electricity if I ran it from home...  |

Just have to see...

Might rethink what I want for chips....

Might rethink what I want for chips.... http://wccftech.com/intel-launches-12-skus-v2...-xeon-e52470-v2-included/ Interesting... But how many can you put in one system? 20 threads is great, but running the opteron 6274 @ 2.2 with 4 in one system, the power usage and output should be really good, if the new V2 intel is doing 20 threads, you would have to run 3 to do the same amount of work, or thereabouts, as the quad opteron system. The power overhead is likely to be higher on 3 systems than on the single opteron based system. Or is it?

Processors should be delivered on Wednesday, so should be able to start putting it together very soon...
----------------------------------------Watch this space, there'll be loads of photos' and some comments...
