  • Choosing Memory for PowerEdge 2850 [on hold]January 27

    Okay, this question is probably going to sound ridiculous, but here goes... I found some old PowerEdge 2850 servers in my school's tech dump. The ones I found came with no power supply, RAM,or CPUs, so I'm attempting to rebuild them, but I've had to

    I've bought a Xeon E3-1230LV3 1.8 GHz CPU, and a Asus H97M Plus motherboard. When I power it up it makes three short beeps. I tested the motherboard with a different Core i7 and a Celeron, and both work fine, so I assumed I had fried the CPU. I there

  • Upgrading CPUs for my HP G5 DL380 - will the cooling suffice?January 6

    Just a month ago or so, I bought my first rack server for some personal number crunching. It's been great fun playing around with and I'm thinking about upgrading the CPUs to get more bang for the bucks ( and noise, lol ). Is it likely that my curren

    Could somebody explain to me what this code means in dimm config? I have E2680 server. Below is the log: N0.C0.D0 : 16 GB (1Rx4) DDR3 - bank: 8, row: 0x20000, col: 0x800, 800 8-6-6 cwl= 5 (6622206A) N0.C1.D0 : 16 GB (1Rx4) DDR3 - bank: 8, row: 0x2000

  • Why is this Xeon designed to be capable of 2 clock rates?December 31

    Why would the Xeon X5650 processor operate on either 2.7GHz or 3.1GHz when it most likely is designed into a system that is always connected to an AC power supply? --------------Solutions------------- From the linked ARK page: Processor Base Frequenc

  • Xeon memory bandwidth specification incongruencyDecember 1

    How can this Xeon achieve the stated 102 GB / s memory bandwidth with the following configuration: Channels: 4 Type: DDR4-1866 The max. theoretical bandwidth would be 59.712 GB / s. The stated figure is approx. 71% higher. --------------Solutions----

  • Is there a specific order for inserting dimms in a server motherboard?November 24

    So I just got an Intel S5400SF server board and I have 8 sticks of 2gb RAM. I was wondering since there are 16 slots, is there a specific order which I should insert the slots in? I know that with normal consumer motherboards you normally skip every

    Why is Xeon processor suited for HPC?July 12

    Among the different specs for Xeon, available here, http://ark.intel.com/compare/87720,84679, which aspects makes it relevant for HPC ? The processor base frequency is less than for Core i7. Why Xeon did not achieve same performance, and why is it no

    How is multiprocessing related to cores and threads?July 6

    I am interested in the Intel Xeon E5-1650 v3 and the Intel Xeon E5-2643 v3 processors. They both have 6 cores and a clock speed of ~3.5GHz. However, the specifications from CPU-world (screenshot) show that the Intel Xeon E5-2643 v3 processor has 2 mu

  • What features of a Xeon E3 processor will not work on an H97/Z97 chipset (and vice versa)?March 14

    LGA1150 Xeon processors appear to be supported on consumer motherboards with LGA1150 sockets. Xeon chips lack an integrated GPU, of course, so onboard video can't be expected to work in this configuration. That much is clear. What other features of a
