AMD Chipsets

Does anyone here have it in over at AMD? I can't seem to get through to anyone that knows the chipsets and I'm looking to use one of the phenom CPU's and an array of Radeon video processors in a motherboard project I'm doing with a propeller bio's. If anyone has any pinout info please let me know. Thanks

    a lot of these new video cards have everything on them to be their own computers, and they have really fast clocks. Anyone isolate one yet? any cuda coders here?

    I tried running some CUDA code on my graphics card a couple of years ago, it worked OK. I've got one of the new cards with a lot more processors on it now, but haven't tried CUDA on that.

    Have a look at what MSI did with the 890FX chipset.http://us.msi.com/index.php?func=proddesc&maincat_no=1&cat2_no=171&prod_no=1986 I can picture laying out a serious graphics processing computer with this chipset. Maybe use some of those new 5970 cores. I was playing with the Ageia physx until they turned it over to Nvidia. I was thinking of cuda but now I see even radeon has the 3d vision system out. I bet someone is going to write an Imax 3d filter for it.

    I have a broken socket AM2+ motherboard with a faulty Northbridge so I'm working on pining out the processor; it looks to me like most of the south, east and west are dedicated to the DDR2 memory, and it looks like they have the memory running in parallel.
    The northern portion of the processor looks to be dedicated to the Northbridge; Northbridge controls the PCI bus and onboard video. And heads to the southbridge. Southbridge looks like it controls the SATA. . . I can't really pinout without pulling the chips but I'll try.
    I don't have a hot air work station or a magnifying glass and that would help.
    These chips look like QFN surface mount, does anyone know where I can get SIP/DIP socket conversion boards?
    I'm already working on the multiphase PWM power plant for my board and I can picture peltier cooling my bus.
    Anyone care to challenge the video card I mentioned? Maybe someone has a broken one to play with?
    If you guys are interested in Realtek audio, I have the blueprint layout for their latest chips that all these motherboard companies are using.

    Oh, you are in for such a shock. They are BGA, and usually on 6-12 layer boards.

    Is that just to keep people like me from following the tracks?
    BGA, I'll look to see if I can find any boards, do you know how many pins they are?

    oh yes, they do make it. Advanced Interconnections; www.advanced.com

    I guess 5 rows of pins would explain that crazy amount of layers.

    These guys over at advanced make some serious stuff.

    The flip-top even has a heatsink, pretty neat.

    I came up with an idea on how to make a hot air nozzle out of a soda pop can to lift these BGA chips, I'll post some pictures if I get around to it.

    If you want to get started with a relatively in-expensive hot air station you many want to check out this forum thread:

    The adapters you quote in the pdf's have 5 rows of pins. The unit's I've seen on PC motherboards don't have free space, they are all pins. Have a look at the underside of the motherboard and you will often find a via for every pin of a BGA.

    Cheap Chinese hot air rework stations will do an adequate job, but if you plan on scrapping chips of old boards and re-using them you'll need a re-balling kit also.

    Yeah, I've been looking at the bottom of the board and can see the little pin holes, along with some SMD components. It's not going to be easy. I have solder paste to rework with but don't have any money to spend on a hot air rig. I need a new video card and DVD drive for my PC first. I think I can make do with a few soda cans and an old hair drier.
