GT610 PCI

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
