    Socket G34

    While "Valencia" may be not for sale yet, our thirst for 6- and 8-core CPUs can be quenched by the new AMD FX CPUs.

    But how's things on the high-end side of computing-land? Can you actually buy a 16-core CPU?
    And the answer is: YES, WE CAN! (now, where did I hear that before?)
    A 2.1 Ghz 16-core Opteron 6272 can already be bought for 536.34 Euro's, while a 2.6 Ghz 6282SE cost 1039.45 Euro's (Do I have to choose? gimmy two of them 6272s, please, and make it pronto)

    And where do we stick it in? At the moment I seem to be able to choose between two SuperMicro boards, of which one does only support up to 8 sticks of RAM (a Supermicro H8SGL-F-O at 239.89 Euro) while the other goes to 16 (the Supermicro H8DG6-F, but it costs 601.90 Euro) and has place for two of those 16-cores. (drool)

    Now before we rush to the store to spend our hard-earned money a word of caution: the Supermicro H8DG6-F might not fit your
    A. budget (the Supermicro H8DG6-F is a wee bit expensive, especially with two CPUs plus memory in it)
    B. case (the Supermicro H8DG6-F is E-ATX format, so only for real BIG towers or racks)

    So we take the 'poor man's solution' and look at the Supermicro H8SGL-F-O. It is of normal ATX format (applause!) and not even as expensive as the top in AM3+ Mobo's, the Asus Crosshair V Formula/ThunderBolt, that comes at a whopping 282.49 Euro.

    What does it offer?
    • Up to 128GB DDR3 Registered ECC or 32GB DDR3 Unbuffered ECC/non-ECC 1600/1333/1066 SDRAM in 8 DIMMs;
    • an onboard Matrox G200 16MB DDR2 (a WHAT? Why no HD 6550?);
    • PCI-E/PCI slots: 1/1/1/3 PCI-E 2.0 x8 (in x16) / x8 / x4 (in x8) / PCI, meaning your HD 7970 can be placed as well. (Didn't you have one already? Crunching can not be done on a Matrox. Crunching-wise, Matrox s*cks. Excellent 2D performance though.)


    You can even connect your old PS/2 mouse and keyboard!
    Now for the lottery.........If I win it, a 1000 Euro CPU is the least of my worries.

    Provided you already have a running G34 board, the bottom prices for Socket G34 CPUs seem to have fallen to an all-time low, at least here.
    A 12-core AMD Opteron 6168 (Boxed) with a TDP of a mere 80 Watt can be bought here for just 115 Euro's -and that's a K10-based Magny-Cours CPU, with 12 real cores.
    When you fancy Socket G34 Bulldozer-based 16-core CPUs you're served with a 80 Euro AMD Opteron 6272 or 6276 or, when you want the latest in G34 design, the 112 Euro Opteron 6376.

    And it can be done even cheaper when you go to 2nd hand sites: the power guzzling (140 Watt TDP) Opteron 6180 I found for 50 Euro's, eight core Opteron 6136's for a mere 30 Euros, 6134's for as little as 25 Euros and 6128's for 20 Euros.

    eBay listing for an ASUS KGPE-D16, Socket G34, with 2x Opteron 6272 (2 x 16 cores, 115 Watt TDP per CPU)

    Wow those are good prices there Dirk, I just wish I had enough to purchase a couple of sets and build a new farm!





    Challenge me, or correct me, but don't ask me to die quietly.

    Jason might be able to do an upgrade

    i have a couple of those to replace a few bad server blades I have, but it is not the most efficient server setup. I found it works better to add a ryzen or 2 in the colder rooms of the house for winter. The HP server stuff I got on a used site had dual 6 cores to start and as a few blades develped issues I replaced them with a few of the dual socket with 12 cores each. This really upped the fan speeds on the enclosure and power consumed. Its a hard sell for me as I am currently finding it more fun to build a ryzen and set it up and forget it.

    You might consider builds with EPYCs...provided you can get to such money
    I also hear good stories about the Ryzen Threadripper 2990WX. It also runs hot (250 Watt TDP), but offers 64 threads while doing that.
    You'd need 5.5 Opteron 12-cores for that amount of threads....and a lot more heat to pump through your house.

    An EPYC 7551 also has 32 cores/64 threads, but has a TDP of 'only' 180 Watt, while costing about half the $$$ of the Threadripper 2990WX.............

    And if you can handle a CPU with a TDP of 250 Watt, you might consider the 200 Watt TDP EPYC 7702: 64 cores/128 threads, or the 64c/128t EPYC 7742, that offers higher clockspeeds at 225 Watt TDP. Unfortunately those two are in the $7,000-8,500 price-bracket.
