My plan is to test whether using a Quadro 2000 (drivers officially supports VGA passthrough) makes for a workable experience before I spend 4x as much on a GTX680 to modify into a Quadro K5000 or a Grid K2. All in all, good enough for a demo, but absolutely not good enough for anything meaningful. If you have more than one CPU you'll only get to the guest's login screen if you disable IRQ balancing. The longest I've gotten out of my 6450 card I've been testing with is about 10 minutes before something odd happens and the driver decided to reset the card - at which point the VM crashes, and the only way you'll get it to boot again without BSOD-ing before the login screen is by rebooting the host. Granted, ATI cards almost work whereas desktop Nvidia cards don't work at all with VGA passthrough without a whole raft of extra Xen patches, but the experience is poor at best. Regarding Xen virtualization, I haven't tried Nvidia yet (my Quadro 2000 for testing is in the post), but I sincerely hope the experience is less appalling than with the ATI. Throw Xen virtualization into the mix and the number of complexities multiplies. Just try getting things working reliable in both Linux and Windows with something like an IBM T221 and you'll find there's a number of pitfalls if you haven't done your research properly to begin with. All you can do most of the time prioritize what you need to not be broken and pick the card which works for that specific environment. Also that SOIC that sits near the straps I believe is the EEPROM.īoth Nvidia and ATI have issues once you start straying from the basics. Will I need any extra heatsink to prevent what happenend to you hero card? In you opinion, will be better for my use to mod it to a dual quadro k5000 or to a K10? Thank very much in advance, Gnif. After finding these posts I adviced him And he purchased a GTX 680 GB Zotac, and I could (tks God) Mod it to Quadro K5000.I'm testing it and will take the GTX 690 for modding too. I am working in a Desktop with a GTX 690 using Blender for Architectuiral Rendering. I am now running on a semi faulty GT220 (random lockups) and an AMD Radeon X300 to get my triple head working, but as you can imagine this is a very buggy configuration. The chip quickly died from overheating when I got excited and let Linux boot into the graphical environment, and there goes my $1000 video card for the greater good, and as such donations are now more important then ever to replace this card now. I was able to locate them and modify the GTX690 to be a dual core Quadro K5000, but I made the stupid mistake of running it without a heatsync on the bridge chip in the middle of the two while testing.
