hi guys I been looking to up my ppd and have found lots of older servers for sale...but how good are they for ppd compared to how much elec they use... for example Fujitsu Siemens Celsius R630 2x3.6 xeon 4gb ram Dell PowerEdge 2800 Server 2x 3.0 xeon 4gb ram HP ProLiant ML350 G5 (470064100) Dual Core 1.8GHz Intel Xeon Server 4gb ram how wud these compare to say a basic i3 with a say 250/260gtx folding?
I have an old hp server folding it has 2 L5420 @ 2.5ghz it pulls about 18-20k ppd It will be up for sale after the chimp challenge has finished if your interested Sent from my BlackBerry 8520 using Tapatalk
If you want maximum PPD, you need to get something with 16 cores or more so you can bigadv folding. If you want to save electricity, avoid GPU folding. This obviously may change at any time. One of the best little rigs you could build would be with a 2600k OC to 4.5Ghz sitting in an mATX board with 4Gb of memory overclocked to 2133mhz ish. If going second hand and you have a spare case/PSU it would cost £250 ish and put out around 30k PPD whilst drawing 150W at the wall. The old Xeon servers you listed will put out similar PPD, but draw 3 times as much power. Cost would be quite a lot less, but you would suffer with the electricity bill. As a general start, what is your budget for buying components? And would this be a dedicated folder, or multi use machine?
would be for folding 24/7 at the moment im using my pc an gpu ...but don't like doing it 24/7... looking to do it as cheaply as possible really would I really get about 30kppd from those servers??
Its old tech, so I would expect them to get around that whilst also heating your house and burning electricity. Keep an eye out for cheap second hand stuff, the newer the tech the better as a general rule, and the more cores the better.
That's why you put them in a nice conditioned data-center. I'm sharing some rack space with a mate who is going to be folding on a dual Quad 3ghz server. Should keep nice and cold and no worries on power.
any guesses on how many ppd id get from one of these IBM ESERVER X SERIES 335 8676-M1X SERVER 2 x XEON 3.06GHZ, 4GB RAM and I think both xeons are ht
well I bit the bullet and got on of these IBM ESERVER X SERIES 335 8676-M1X SERVER 2 x XEON 3.06GHZ, 4GB RAM this is gonna be a trial thing..something to play with.. hopefully im going to try Ubuntu desktop on it..another new thing for me.... since this will be folding 24/7....will 4gb memory be enough or should I have the max 8gb in there??
ok that's cool ill wait till it turns up tom hopefully... then try and setup Ubuntu on it... and go from there
Installing ubuntu shoudl be pretty straight forward. Probably best to install from a USB stick. Ubuntu web site gives details on how to do this. Godo luck.
I have folded on a LOT of different make/model servers so firstly make sure its at least the Core 2 Quad family of Xeons (socket 771), the P4 family which will be the ones generally listed as 3.0 and 3.2ghz Xeons will EAT electricity, heat like a blast furnace and only give you approx 4-6000k Even the Socket 771 Xeons are not all that any more, I borrowed a HP DL580 with 4 x quad core Xeons @ 2.4ghz each for the Chimps Challenge, I thought 16 real cores, no hyper-threading should come in OK, but no it was just too slow for bigadv, TPF was outside the minimum return time so all I could do was let it crunch A3 cores which is making it produce around 40k PPD
