Hi all, Just starting to really get into the folding side of things, and was becoming curious about booting up some old 1U Servers i have knocking about to assist... Basically they're two HP DL140 G2's with (i believe!): * Unit 1- socket 603 dual processor board, with 2x single core 2.4GHz Xeons * Unit 2 - socket 604 dual processor board, with 2x single core 3.6GHz Xeons There's around 2 - 4 GB of RAM in each too i think. Does anyone have any experience with these processors or similar? Is it worth running the SMP client with two single core CPU's? and baring in mind that Unit 1 is around 300W, and Unit 2 is probably about 400W (say 700W combined power sucking), are the PPD/Watt counts likely to be any good? I think that these are the CPU's in question: Unit1's CPU: http://ark.intel.com/products/27269/Intel-Xeon-Processor-2_40-GHz-512K-Cache-400-MHz-FSB Unit2's CPU: http://ark.intel.com/products/27088/64-bit-Intel-Xeon-Processor-3_60-GHz-1M-Cache-800-MHz-FSB Thanks in advance for any tips!
