Re: [Xen-users] Is it possible to mod a Geforce GTX 560 graphics card into a Quadro?

Very interesting mail! Under the impression that BIOS were modified using something like perl, awk, sed for ID (to inject). I don't think that tool like the old rivaturner was used :)

Will wait  for reading the next articles on your blog :)

Kind regards.

It isn't. There is no equivalent Quadro model to modify it into.

Cards that can be modified using a BIOS modification only:

1)    From:    GTS450 (only 192-shader 1GB GDDR5 model!)
    To:    Quadro 2000

2)    From:    GTX470 (448 shaders, 1.25GB)
    To:    Quadro 5000

3)    From:    GTX480 (480 shaders, 1.5GB)
    To:    Quadro 6000

4)    From:    GTX580 (512 shaders, 1.5GB, 3GB)
    To:    Quadro 7000
    Note:    Quadro 7000 isn't supported for "MultiOS" and VGA
        passthrough will not work with it (tested, Quadro
        [256]000 work fine, but a GTX580 modified to Quadro
        7000 does not work with Xen VGA passthrough. So don't
        get this one.

The 6xx series requires hardware modification (soldering 0402 type
surface mount resistors - not for the faint of heart, but doable, I have
successfully modified a GTX680 last weekend)

5)    From:    GTX680, GTX690, also reported to work with GTX670
    To:    Grid K2

Untested, but should work similarly to the other 6xx series mods with

6)    From:    GTX650Ti/GTX650Ti Boost
    To:    Grid K1

If you only want a low end card for virtualization testing, the price
gap between a real Quadro 2000 on eBay and a GTS450 has shrunk to the
point where it's probably not worth the hassle modifying the BIOS unless
your time really is worthless, so my advice would be to just get a
Quadro 2000.

If you are interested in higher performance (e.g. for gaming), GTX480 to
Quadro 6000 mod works very well (~$120 on eBay for a GTX480 vs. ~$900
for a real Quadro 6000, spending an hour doctoring the BIOS is certainly
worth the difference).

It depends on how much effort you want to put in, and what you plan to
do with the card (a real Quadro has some extra uncrippled GL
functionality in the silicon which makes it faster than a modified
GeForce in some CAD apps, but it makes no difference in gaming and
general purpose number crunching). See here for some benchmarks between
GTS450 and a Quadro 2000:


If you want something cheap enough that requires no extra effort, a real
Quadro 2000 is probably your best option.
