    ECS K7SEM (V3.0C) Where is the socket??

    This PC was a freebie. It had some interesting stuff.

    ECS K7SEM (V3.0C) without a CPU socket I 've never seen something like this before. I can't remove the cpu! It is soldered to the motherboard! Why would anyone do that??

    Btw the motherboard has OST caps in VRM. Good choice for ECS.... The medium size caps are G-Luxon.

    There is a KA7500B ic on the motherboard!! Why?? This is used in switching power supplies!

    Another highlight is the SDRAM dimm with a heatsink. Firstly I thought it was a Rambus dimm!

    There is also a 40GB Ide 7200 hard drive unknown brand "ExcelStor" with a "Jupiter" logo. On the bottom side the controller has IBM ic.

    Finally, a PCI USB 2.0 card provides 4 USB ports at the back of the PC and 4 USB ports at the front side, by taking a 3.5 slot.

    The power supply is the Macron Power OEM posted here:

    What do you think?

    ECS released a bunch of boards with "onboard CPUs" back then.
    They either had Durons or Via C3's on them, and the BIOS reported ridiculous numbers like "1800 PRO CPU" for an 800MHz Duron.

    Yours has a 950MHz AMD Duron, so i bet it'll report 2200 PRO or something in the BIOS lol

    Excelstor HDDs are mostly IBM/Hitachi OEM drives (made under license).
    The RAM really is oddball though.. that's exactly the same heatsink style as used on RDRAM/RAMBUS.. what the hell

      The CPU VRM is also a switching power supply. They just cheaped out instead of using one of the dedicated, higher efficiency controllers, as on such a board it is not needed.

        At least this isn't the "2000+" board. It used an 800MHz VIA C3. A 400MHz K6-2 is faster.

        That computer looks like it was assembled with the cheapest parts they could find. They even used a generic hard drive.

          The processor is reported as "Pro 1400+". Its actual speed is 997MHZ, measured with THG clock.

          The cpu fan was making a terrible noise and was not running well. I put some oil at the bearing and it got better.

          There is also integrated SIS graphics card, automatically enabled when there is no VGA at the AGP slot. I put a Geforce2MX 200 32MB instead.

            lol.. so they overclocked the 950MHz duron that's on there

              I saw so many dead SEM's when I worked for goodwill computer works. like 8, usually bad caps or a burned out cpu

                With only 4 caps on VRM low, I don't see how that's a good choice at all. And these are OST RLP, which if I remember correctly are close in specs to Chemicon KY - in other words very underrated for the application. They should have been at least OST RLS (about equivalent to Chemicon KZE and Rubycon ZL).

                That's a good computer for testing stuff, and maybe some office apps, but not more.

                  Using that number of caps on AMD boards is not so unusual though. From what I have seen there was no need for ultra low esr back then at the time of P3 and Athlon cpus. I agree that it is a little worrying and I am not a fan of ECS boards, but if you take into account that this mobo comes with on-board Duron cpu, which is not so power hungry, it may get away with it.

                    Possible to convert eMMC Socket to a micro SD Card socket?
                    by Isabella91
                    I have seen many posts where the eMMC can be read via a SD card reader, however can the opposite be achieved?

                    Read/Write a Micro SD Card from an eMMC Socket.

                    I have a Motherboard with a Kingston BGA153 ball socket, using HS400 bus mode, which is 8bit, as Micro SD is usually 1bit or 4bit mode, I accept that a loss of speed in read/write will occur, but I would sill like to convert.

                    Theoretically speaking, Im thinking if I hard solder DAT0-3 from eMMC to SD Card Reader, this should force 4-bit mode, or only DAT0 to force 1-bit mode.

                    Acer AN515-57-577G JDIMM1 socket not working.
                    by warsztat
                    Hello, Acer AN515-57-577G JDIMM1 socket does not work. GH51G LA-L181P, 2x DDR4 RAM, both good, both work well in JDIMM2, neither works in JDIMM1. The laptop displays BIOS, when the JDIMM2 socket is occupied, you can run Linux on USB, then everything seems to work ok, there is internet access and you can browse the contents of the 512 GB SSD in Windows, but starting Windows ends with an eternal spinning circle, maybe there are corrupted files. When the RAM is inserted into the JDIMM1 socket, the laptop starts but there is no image and the downloaded current does not change and the output is ~2.25A....

                    CPU socket replacement soldering profile
                    by Geomih
                    Hi All - I am hoping someone can help with some pointers (complete noob here!)

                    I have recently purchased a Scotle HR460 BGA reball machine (it's a bit old and I think the company no longer exists either), but as far as I can tell it is a competent and unmolested machine that should be good enough for my needs.
                    My biggest problem is that it came with no profiles, and I must re-create all of them from scratch, something that is very scary for someone that doesn't really know what they are doing.
                    The simple stuff like a small memory module isn't a big deal because there are

                    ASUS Sabertooth 990FX REV.2 bios chip problems, probably socket shorted?
                    by Biessea
                    Hi there,

                    I'm a technician and a computer/retro computer lover.

                    I just bought a great Sabertooth motherboard (I really love the colours and the ASUS military scheme) to install a nice FX-8320 from AMD and make a gaming computer with a Geforce GTX 970.

                    For the first time I had problems with the system, but I solved and then correctly booting, I installed Windows 10 and then I started to overclock the system. I reached a stable configuration of 4,8GHZ with 1,475v.
                    Then I saved fan configuration, and other parameters, and saved to the overclock profile...
