I'd love to try an actual Zotac bios on this card but haven't been able to find one online. If you've got a bios from a PCI GT 610 (or maybe even the PCIe version) let me know and I'll try it.

Revision as of 18:52, 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?

  • GT610 2.jpg
  • GT610 3.jpg
  • GT610 4.jpg

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:

38:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1)
38:00.1 Audio device: NVIDIA Corporation GF119 HDMI Audio Controller (rev a1)

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

From here on the output is typical of a GT 610. Note the Zotac string ZOTAC International (MCO) Ltd. GF119 [GeForce GT 610]

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.

  • GT610 6.jpg

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:
