    we've installed these DDR3 modules in production servers based on X8SIL/X8SIL-F boards with good success:
    Crucial CT25664BA1339, 2G DDR3-1333 non-ECC, micron 256Mx4
    Kingston KVR1333D3N9/2G, 2G DDR3-1333 non-ECC, kingston or elpida 128Mx8
    Crucial CT25672BB1339S, 2G DDR3-1333 ECC registered, micron 128Mx8
    Supertalent W10RB4G8S, 4G DDR3-1066 ECC registered, samsung 128Mx8

    supermicro has now put Crucial CT51272BB1339Q 4G DDR3-1333 ECC registered on compatible list, but we've not get a chance to test it yet.

    Is this the same as CT51272BB1339? Can't find it with the Q.

    Hi Chong, is the Supertalent W10RB4G8S Dual or Quad rank?

    Has anyone tried this yet? I can't find it with the Q either (even on the Crucial website) but if the CT51272BB1339 that seems to be around is the right stuff, then it's readily available and at a good price to boot.

    The difference seems to be a Q suffix indicates quad ranked ram, and an S indicates single ranked ram, with no letter suffix being dual ranked. Hopefully that bodes well for the non Q version...

    Okay, interesting development on the CT51272BB1339 ram. I found a comment on the Crucial website here that states "Crucial website says this memory is compatible with the ASUS P7F-E motherboard. In actuality, it is not. I am not going to give the actual memory a bad rating but beware, the compatibility chart is incorrect for this particular motherboard."

    As the P7F-E motherboard is an LGA1156 board with a 3420 chipset it probably doesn't bode well...

    I can confirm CT51272BB1339 does NOT work with SM Ibex peak skt1156 boards. CT51272BB1339Q is the quad rank version, which I have not tried.

    @Chong - Did CT25672BB1339S work for you? CT25672BB1339, the dual rank version works fine, but the single rank version has been nothing but problems, even in configurations supposedly supported by SM.

    Anybody have a 4GB DDR3-1333 ECC REG x8 dual rank stick they've used successfully to this point?

    Okay it's good to know that the CT25672BB1339 dual ranks are working as all the ones I keep finding around the place seem to be the non 'S' version anyway.

    Given that the W10RB4G8S chips are practically non existent, what about the Kingston KVR1066D3Q8R7S/4G mentioned earlier? I've heard a few reservations about using Kingston ram in anything but they're 4G a stick, well priced and seem to be available in good numbers. Any thoughts on them?

    OK, let's end these confusions by reviewing this giant list of Intel validated ECC registered DDR3 1066/1333 modules
    http://www.intel.com/technology/memo...lts.htm#1DPC_1
    the list is published for Xeon Gainestown LGA1366 which can take any registered DIMM using "x4" or "x8" DRAM dies. however, Lynnfield LGA1156 CPU takes only modules using "x8" dies. thus, you go down the list and identify all "x8" modules in the column "DRAM die", and those are THE ONLY modules shall be compatible with supermicro X8SIx series LGA1156 server boards regardless they are currently listed on supermicro, kignston, or Crucial web pages or not.

    again, RAM compatibility on LGA1156 platform is subject to the IMC (internal memory controller) on Lynnfield die, and it's nothing to do the motherboard's northbridge (external memory controller in the past) because there exists none of MCH (memory controller hub) no more on socket 1156 boards!

    also, don't confuse single-rank (SR), double-rank (DR), quad-rank (QR) with "x4"/"x8" DRAM dies, these terms are referred to different things. Lynnfield CPU supports total of 16 ranks. thus, if you use quad-rank modules, the max RAM you can have on LGA1156 server board is either 16G (4x 4G) or 32G (4x 8G). if you have a server board with 6x DDR3 DIMM, such as X8SIE-F, then you must use dual-rank modules to get all 6 modules working (12G: 6x 2G or 24G: 6x 4G).

    specifically, CT25672BB1339S (2G, 1333, dual-rank, 1Gx4 chips) won't work with Lynnfield because it's using "x4" chips! CT25672BB1339 (without "S") will because it's using "x8" chips.

    don't buy the one without "Q" because CT51272BB1339 (no Q) is using 'x4' DRAM chips which will never works with Lynnfield's IMC.

    if you can't find any CT51272BB1339Q in your region, these DDR3-1066 4G modules works with Lynnfield too: "CT51272BB1067Q.36SFD1" and "CT51272BB1067Q.36FF1". they are all using "x8" chips.

    Is there anyone actually stocking this in any sort of quantity? Seems very light on the ground, and given the price of most of the other compatible ram the Kingston seems about the only other affordable and readily available 4GB Reg ECC chips.

    You mentioned them yourself earlier in the thread. How have you found the Kingstons? And willing to share anywhere the W10RB4G8S can actually be had?

    The Kingstons have gone up a lot in price now, we had to find an alternative and the W10RB4G8S is it.

    SuperTalent has some type of close relationship with MALabs distributor, who else has owns eWiz.com
    We are getting the W10RB4G8S from MALabs.

    I will PM you the email of our rep. at MALabs where you can order it from.

    forget about getting W10RB4G8S from Ma Labs (who owns supertalent)! we are malabs/supertalent direct, and the words we got from them is that they can't get hold of the Samsung "x8" DRAM chips at this time to make more modules. it's going to be after X'mas or early Jan before they are able to supply those modules.

    you may have better chance to find it from some e-tailers who have existing stocks of them.

    Yeah that's not good news. Most of the servers we want to build will be on the X8SIL-F and only need 8GB of ram so the quad ranked Kingston chips should be fine, but a couple of the servers were supposed to have X8SIE-F board with 24GB and as I understand it that's not going to work with the quad ranked chips...

    Got to hand it to Intel for creating yet another memory debacle.

    I just finished building a system with an X8SIE, a Xeon X3450, and 4 modules of Kingston KVR1333D3D4R9S/4G. Unfortunately the system does not boot (no beeps, no video).

    If I plug only 1 module in, or no modules at all, I get the long "no memory" beeps. Am I correct in assuming that the problem I am having is probably caused by the memory?

    If I read this thread correctly, I am thinking that 4 modules of Kingston KVR1066D3Q8R7S/4G should work?

    Notice how it is an x4 chip, not an x8 chip. Lynnfield IMC does not support x4 DIMMs.

    Thanks for your prompt reply. I will return the 1333 MHz DIMMs and order the (hopefully) right parts. I am very glad I found this thread (I was thinking I'd get the motherboard replaced)...

    I have had problems with Kingston RAM on Supermicro boards even when they were the correct spec. If you order the RAM from Supermicro, they will work for sure.

    I just checked again on the memory list for the X8SIE on the Supermicro site, and the Kingston module I mentioned appears among the approved 4GB ECC RDIMMs.

    At least I think it is the same module. They differ slightly: the one on the SM site is listed as "KVR1066D3Q8R7SK3/12GI", instead of "KVR1066D3Q8R7SK3/4G". Only the digits after the "/" change: is this the same module?

    I would have posted a link to the SM site for clarity, but apparently I cannot do that yet.

    There is a handy search tool on the Kingston website that you can use to look these up if anyone is interested in particular chip numbers at http://www.ec.kingston.com/ecom/conf...w.kingston.com

    KVR1066D3Q8R7SK3/12GI does appear to be a 3 pack of the KVR1066D3Q8R7S/4G chips, and as they are x8 they'll be fine. Depending on the price the 3 pack you might be able to find the single chips cheaper (or not). Just remember that these are quad ranked chips and you can't use more than 4 of them on a single board.
