  • How do I recognize whether my M10000 has a Nehemiah Core?

    I've bought a Via EPIA M-10000. In the description, the store stated that the processor would be the 1 GHz Nehemiah. I received the board today and want to make sure that this processer is indeed a Nehemiah, because I'm not sure about it .

    I don't have a harddisk and time to install an operation system, but I connected the mainboard to a ATX Power Supply to see the boot screen and bios.

    When booting, the screen displays "VIA C3 1.0A". The bios date is "03/17/2003".

    Could someone tell me if this is the Nehemiah, or could someone describe where I should look for?

    Next time atleast :}

    The serial number should start with an F if it is a Nehemiah - anything else (eg C ) is an Ezra... (Serial # is on the box and on top of the parallel port).

      You're completely right, my fault. I did a quick search but should have searched more thouroughly.

      Anyway, I found out that the serial number is not always a correct indicator for the processor type (and that a sticker with a serial number sometimes misses). A better way using the processor id is described in the document: http://www.techcase.de/Nehemiah.doc.

      For the dutch audience: I bought my M10000 Nehemia at http://www.alternate.nl for EUR 159,- which is an acceptable price. See: http://www3.alternate.nl/cgi-bin/inf...ocket%20370%20.

        the C and F serial number deal isn't always true. I've read about a lot of nehemiah boards that have C serial numbers.

        I've done some searching about this as well and haven't come up with much. I checked your two links and they ended up being posts i read over the past few days that don't really offer any info on how to tell the difference.

        All that I've found for how to tell have been suggestions to check the S/N (which isn't accurate) and to load windows and look at what processor it registers. I'm still waiting on my IDE adaptors so I can't get the 411 on mine until they come in.

          I responded while in one of my classes, i wasnt exactly putting too much thought in it.

          Joys of google: http://forums.viaarena.com/messagevi...threadid=38072

          Here are some tips:

          If you can look on the box itself, there is a white bar code sticker that also says EPIA M10000 followed by on the box itself a "Made In China" slogan , if beside that slogan there is an affixed green sticker -it is an Ezra-T core.

          You can ask your retail outlet if they know before you purchase, if they're not sure ask them when they received the board in stock, if it is before April then it is probably then Ezra-T core.

          If you have the opportunity to boot up the board then you will see it in the BIOS as Nehemiah.

          If they have 2 versions of the EPIA M10000 the Nehemiah version will likely be at least $US 10.00 more expensive.
          Another good one is at viarena:

          I will be able to test tonight if the ucode Id is 0691(Nehemiah) or 0689 (Ezra-T). I was hoping theat I would have received the Nehemiah since I ordered this just last week.
          thats if you can boot, but then you could have just checked in your os. Which im assuming is not an option?

          I dunno, hope that helps.

                  Sorry to keep this discussion going, but I just bought my M10000 from Essential Computers http://www.essencompu.com/nupplysingar.asp?ID=3484 and it's an Ezra (according to the system properties screen in XP).

                  Before I go into battle with these guys, what is the drawback of the Ezra vs Nehemaih? Is there a significant hit in performance? Are there any othe major drawbacks that I should be aware of?

                    there is a significant difference when comparing divx playback (or was it dvd) ... something to do with better floating point calculations in the nehemiah?

                    do a google for ezra nehemiah or something ... ther'es a number of articles.

                    you definately want the nehemiah ... how much did you pay? ezras are only worth about $110

                      I paid $150. But Essential was "out of stock" (even tho I called ahead to make sure they had stock) and had to have it drop-shipped from someone in Ft. Lauderdale.

                        Actually, I've done quite a bit of Googling. I haven't found much on the VIA product, but I'm becoming quite an Old Testament expert...

                        Anyway, I found a snippit on Geek.com
                        VIA - C5X - (C3 - Nehemiah)
                        The VIA Nehemiah is still officially called the C3, but it uses the C5X core developed by the WinChip team that Via acquired. Like previous Via C3 chips, it's aimed at the bottom of the market. The C5X is the successor to the Ezra / C5C core and supports Intel's SSE extensions with 2 SSE units and a 16-stage pipeline. The FPU of the C5X runs at full clock speed, unlike previous C3's which had 1/2 speed FPUs.

                        The new Nehemiah C3 adds the "Padlock Data Encryption Engine" whose main feature is a speedy Random Number Generator that creates random numbers from static inside the chip. It contains 4 more pipeline stages than the old Ezra-T core, coming up to a total of 16 pipeline stages. The 64K L2 cache features 16-way associativity.
                        This sounds like "grounds for return" to Essential.
