| − | ''' | + | For some time now I've been on the lookout for a "modern" GPU with a PCI interface to breathe some life into my older machines without breaking the bank but it was never much of a priority. That is until a few weeks ago when [https://twitter.com/DosFox1/status/1284214493539708929?s=20 DosFox posted about an odd unbranded PCI Nvidia GT 610 on Twitter] so I decided to pick one up myself. Soon enough my "MQX POWER GeForce GT610 1GB PCI VGA,DVI,HDMI 3D Video Card Graphics" arrived and this card is a bit of a mystery. The only branding on the card is from "MQX POWER" but it looks an ''awful lot'' like a Zotac card based on the orange ports and black PCB. |
| − | + | Zotac did produce a [https://www.zotac.com/au/product/graphics_card/gt-610-pci PCI version of the GT 610] but with only 512MB of GDDR3 video memory. | |
| − | + | They also made a PCI version of the [https://www.zotac.com/us/product/graphics_card/gt-520-pci GT 520] with 1024MB video memory. | |
| + | |||
| + | So what are these cards actually? | ||

| + | The GT 520 and GT 610 have nearly identical circuit boards, so much so that the product imagery for the back of the GT 610 '''has the sticker for a GT 520''' under the edge of the heatsink! This makes sense because both cards use the same Nvidia GF119-300 chip, and even the same clock speeds. The MQX card uses the same heatsink as the Zotac GT 610 Synergy. | ||
| + | |||
| + | Lets dig a bit deeper. | ||
| + | |||
| + | After removing the heatsink and cleaning off the thermal compound that was dryer than the Sahara desert (are these cards used??) we can see the Nvidia GF119-300-A1 chip and four [https://www.skhynix.com/product/filedata/fileDownload.do?seq=2450 Hynix H5TQ1G63DFR]. This "MQX" card is clearly a re-branded Zotac. | ||

| − | + | After installing the card in a PC the first problems come up; namely that this card wont work before the OS loads, and my test PC wouldn't even POST if it was the only video card in the system. Not a good sign. | |
| − | + | After installing a second video card so I could boot, the MQX card presents 3 PCI devices: | |

Latest revision as of 20:27, 5 August 2020
For some time now I've been on the lookout for a "modern" GPU with a PCI interface to breathe some life into my older machines without breaking the bank but it was never much of a priority. That is until a few weeks ago when DosFox posted about an odd unbranded PCI Nvidia GT 610 on Twitter so I decided to pick one up myself. Soon enough my "MQX POWER GeForce GT610 1GB PCI VGA,DVI,HDMI 3D Video Card Graphics" arrived and this card is a bit of a mystery. The only branding on the card is from "MQX POWER" but it looks an awful lot like a Zotac card based on the orange ports and black PCB.
Zotac did produce a PCI version of the GT 610 but with only 512MB of GDDR3 video memory. They also made a PCI version of the GT 520 with 1024MB video memory.
So what are these cards actually?
Physical comparison
Zotec provides high resolution images of both the GT 520 and GT 610
GT 520 Front
GT 520 Back
GT 610 Front
GT 610 Back
GT 610 PCI-e Synergy Edition Front
The GT 520 and GT 610 have nearly identical circuit boards, so much so that the product imagery for the back of the GT 610 has the sticker for a GT 520 under the edge of the heatsink! This makes sense because both cards use the same Nvidia GF119-300 chip, and even the same clock speeds. The MQX card uses the same heatsink as the Zotac GT 610 Synergy.
Lets dig a bit deeper.
After removing the heatsink and cleaning off the thermal compound that was dryer than the Sahara desert (are these cards used??) we can see the Nvidia GF119-300-A1 chip and four Hynix H5TQ1G63DFR. This "MQX" card is clearly a re-branded Zotac.
PCI identifiers
After installing the card in a PC the first problems come up; namely that this card wont work before the OS loads, and my test PC wouldn't even POST if it was the only video card in the system. Not a good sign.
After installing a second video card so I could boot, the MQX card presents 3 PCI devices:

The GF119 has a PCIe interface so a PI7C9X111SL PCIe-to-PCI chip is used to connect the chipset to the PCI bus.

Dumping the BIOS
Clearly something weird is going on, so lets take a look at the bios itself which is stored on a 64kB Pm25LD512 SPI flash chip on the back of the board.
I read it using flashrom over SPI using a Raspberry Pi which was completely painless.
The dumped bios is available here: File:Flash Pm25LD512.bin.zip
flash_Pm25LD512.bin md5sum 10b158b890b14f93f5dfaeac3b7c7672
Nothing immediately seems out of the ordinary to my untrained eye but there are a few notable strings:
IBM VGA Compatible P08/04/19 GF119-300 P1310 SKU 0001 VGA BIOS (VB1) Version 75.19.1B.00.01 Copyright (C) 1996-2011 NVIDIA Corp. GF119 Board - 13100001 PLEASE POWER DOWN AND CONNECT THE PCIe POWER CABLE(S) FOR THIS GRAPHICS CARD 13100001_vb1.romGF119-300 DT P1310 SKU 0000|0001
Based on https://www.techpowerup.com/vgabios/ version "75.19.1B.00.01" appears to be meant for GT520 cards but this bios has GT610 strings instead.
I tried flashing various GT520 and GT610 PCIe bioses to the card with no success. Only the original bios would work properly and I can't find downloads for any of the GT520/GT610 PCI bioses. If you have a copy of a bios for a 13100001 PCI board with 810/667 clocks please let me know :)
