I converted a Zotac GT640 2GB into a Grid K1. All seems to be recognized as supposed (Grid K1). I am able to use the card in XenServer as Passthhrough, however I am unable to use the vGPU capabilities.

Here´s what I did so far:
- Installed a XenServer 6.2 Hypervisor.
- Upgraded it with SP1 and added the following HotFixes: SP1009 and SP1011
- Installed NVIDIA-vgx-xenserver-6.2-340.57.i386.rpm
- Disabled the "64-bit Memory Mapped I/O" in BIOS and Restarted

I am able to see the virtual GPUs in XenCenter (and I am able to add them to the VMs), however, I cannot boot them since I always get this error in messages log:

Has anybody been able to successfully virtualize a converted Grid K1 GPU in XenServer?

So, I modded my Titan Black to a K5200 and now I want to do some 4k gaming. Has anyone tried a 'pro' card with a G-Sync compatible monitor?
TBH, G-Sync isn't the highest of priority for me, just want a good future proofed 4k panel but G-sync working would be a bonus.
Anyone?

hi, i am the owner of a quadro k0000, and have read much here and am impressed with this topic.

have u created a wiki of all the card you have successfully modded. that would be really nice.

since i am just starting to learn how to effectively use this card for rendering etc. i was wondering how to create a tesla type card to help with the calculations required for cad/cam etc.

has anyone been able to do this? any help would be appreciated.

peace,

ed

Hi mosmo, can you point me to what you did exactly to mod your titan black to k5200. esp what bios did you use. thx

The going rate for Quadro 6000 on ebay is under $650.
Note: Quadro 6000 (Fermi), NOT Quadro K6000 (Kepler).

Thank you for your help, so I bought a used 6000 quadro

1) Wait, HOW?! They don't even have the same amount of cores.
2) Guys, is it possible to hardmod a 750 Ti to K620? I am a 14 year old that is currently taking EDT in my high school, and desperately in need for a professional GPU for SW real mode. I could go with any GPU, but then I also do games on Friday nights, so the 750 Ti is a great choice.

When I say modded to a K5200, I mean, it's presented to ESXi as a K5200 but it's really a beefed up 780ti with 6GB of memory instead of 3GB.
3dmark scores are similar or slightly better than my previous EVGA 780ti SC.

ExplicitNuM5 · « **Reply #1157 on:** December 22, 2014, 11:24:53 pm »

So it's recognized in VMWare ESIx as a passthrough. You caught me.

ed00 · « **Reply #1158 on:** December 28, 2014, 04:26:54 pm »

i am still reading this thread, but a quick q? is can i convert my k4000 to a higher k5000 or k6000 with just a bios change??

ExplicitNuM5 · « **Reply #1159 on:** January 02, 2015, 06:34:35 pm »

I don't think so. Different cores.

ed00 · « **Reply #1160 on:** January 07, 2015, 07:16:28 pm »

thank you,

now with a k4000 and i am just learning about ESXi and the idea of using it for maya as a k5200 really sounds interesting, could it work?

xeon 1225 v3 with 16g ecc, any help would be appreciated.

thx, in advance

Just modified my two Geforce 650 TI Boost's to K4000s last night. Also bumped up the clocks, fan, and power level in bios mods. Very nice for budget cards now.

Does a hacked NVidia GTX into Quadro card support NVidia GPUDirect? Has anybody tested that?
If anybody has a hacking guide for Evga GTX 770 I can test it with Blackmagic Decklink Quad card for video capture.

Hi! I'm on this forum first. I have problems with VGA passtrougth (win say code 43 error). I have read that it is necessary to turn the card into quadro. My graphics card is Palit 550 TI GF116, here are the pictures:
front back
crystal
chip near connectors v2
chip near pci-e, below
near pci-e, upside
gpu-z
I flipped through the topic and found mainly pictures where resistors are located next to the chips and I made a couple of photos about them. Have a chance? Which method of finding the group of resistors? View current ID cards and find the corresponding face value resistors? May be necessary to edit the bios?
Thank you!

UPD1: #202 post, GTS450 from this report - a copy of my GTX550. Only different crystals.
UPD3:My dev id: 0x1244. I need to thinking. I do not understand how to choose the resistors ... I need an algorithm.. GTX550ti - GF116, GTS450 - GF106... this is not good... not working or downgrade?
UPD4: My resistors:
1 - 40k
2 - 24.2k
3 - empy
4 - 45.5k
5 - empty

I'm sorry if this has been suggested before but I think this thread should have some kind of wiki created for it. So people don't have to read through the 77 page thread. You could classify stuff by the card type and then have a general page that describes the whole process. Do you guys think this would be valuable? Maybe I'm missing something and this has already been done.

Great idea!
Who will spend his time doing it?

@C_Coffie, This "idea" has now been posted several times in this thread, just search it for "wiki". Please go to http://gpumod.wikia.com/wiki/Gpumod_Wiki or http://aidivn.wikia.com/wiki/NVIDIA_HAcking_Wiki and contribute some information.

Hi everyone,

What is the current state of affairs with VGA pass-through using ESXI/Xen? Is the best performing solution a Nvidia GTX 780 TI converted to a Nvidia Quadro K6000 via hard-mod?

I did just that and it performed very well. I now have an EVGA titan black 6GB with Kraken G10 modded to a 5200. Works fine in ESXi 5.5.

Thanks for letting me know. Just curious, with the GTX 780 TI being detected as a Quadro K6000, I'm assuming all of the GeForce software features (such as ShadowPlay) are disabled? How was the performance compared to a non-virtualised GTX 780 TI? Also, why did you hard-mod your GTX Titan Black to a Quadro K5200 (and not a Quadro K6000)?

780ti about the same mod vs unmod. My black get around 5300 3dmark extreme. I am not sure that there is a difference in performance between 5200 and 6000 since it's a geforce card all the same, just wanted the black for 6gb mem and UHD res.

Thanks for replying (again). I understand, I just thought that the Quadro K6000 would have been the better option (since it has the same core configuration as the GTX 780 TI and GTX Titan Black).

Wow, so Nvidia have come up with the Titan X (12GB) , no doubt something to compete with the new AMD offerings 3xx?
Will buy it and probably try to mod it to Quadro counterpart.

I've bought ASUS GT640, but unfortunatelly can't find the correct resistors to mod the card into grid K1 for my ESXi lab. Can you please help me with the location of R1 to R4 ? Thanks in advance. Photo attached.
