Why Is My Graphics Card Detected as an R5 M240 Instead of an R7 240?
Asked by

I bought an older graphics card advertised as an AMD Radeon R7 240 for an aging PC. After installing it, GPU-Z identifies it as an Radeon R5 M240 instead. The card looks like a Sapphire R7 240 and has a sticker claiming it is an R7 240 with 2GB of DDR3 memory, but the R7 240 driver fails with an error saying the AMD hardware is unsupported. Is this a mislabeled or counterfeit card, or could something else explain the detection?
Answers
Some inexpensive cards are sold with desktop-looking coolers and labels while actually using a Radeon R5 M240 mobile chip. That would explain both the GPU-Z result and the Radeon Software Error 182: the R7 240 driver does not recognize the installed chip. Check the GPU-Z name, device ID, and BIOS details, then compare them with the seller’s listing. If they identify an M240, treat the card as mislabeled or counterfeit and request a refund rather than trying to force the R7 240 driver.

The hardware identification comes from the GPU’s firmware and device ID, not just the sticker on the cooler or PCB. If GPU-Z consistently reports an R5 M240, the most likely explanations are that the seller shipped the wrong card or that it is a rebranded mobile M240 mounted on a desktop-style board. You generally cannot make it genuinely become an R7 240 by changing drivers.
MellowQuasar47: The board looks almost identical to a Sapphire R7 240, and the rear sticker also says “R7 240 2GB DDR3,” so I’m wondering whether the label was simply added to a different GPU.

MellowQuasar47: That seems likely. I tried installing the R7 240 driver, but the installer said no supported AMD graphics hardware was detected.
