GPU 750 TI cannot be overclocked (claimed 750ti model). Is this a fake?
GPU 750 TI cannot be overclocked (claimed 750ti model). Is this a fake?
I purchased a computer that looked too attractive for its cost, it was a troublesome website but I considered the risk to be acceptable. For 220$ I've acquired an I5-2400s and a model that seemed to be a 750ti. It worked as expected, yet I wanted better performance, so I enabled afterburner. I wasn't able to overclock anything; when I adjusted the slider and applied changes, it would reset. Voltage was the only solution.
After some research, I suspected my GPU might be fake. I ran gpu-z and discovered that the clocks were normal, the bus was functioning, shaders were intact, and everything appeared typical of a genuine GPU (except for memory clock).
GPU Clock: 1020 MHz
Memory Clock: 1350 MHz (expected 5400, but some programs show it as 2700)
Bus Width: 128 Bit
Texture Fillrate: 40.8 GTexel/s
Pixel Fillrate: 16.3 GPixel/s
640 Shaders
1870M transistors
etc...
What caught my attention was the subvendor—Acer? I checked the device ID, and only a few of the codes matched products.

Memory type: GDDR5 (Samsung), I hadn't heard Samsung producing memory for NVIDIA before.
I’m just curious if it’s possible to overclock my card, since the fake build doesn’t seem to be a major issue, and it still performs reasonably well like a genuine 750ti. The GPU shroud appears as described; the blue stripes look green to me, and the fans display a yellow NVIDIA logo.
I believe it might be a fake too. The shroud shows no branding, which is suspicious. Also, fake GPUs with matching fan shrouds have appeared in some videos:

Samsung makes memory for cards, but where did you purchase it? Use Run Speccy to check the card details. It seems like a fake.
It's a marketplace similar to eBay in my country, where the seller received positive reviews. I considered purchasing because many of these GPUs are popular in my region, and the images showed them clearly. I was curious about what the 750ti looked like.
I am quite certain it is a fake as well. Examining the shroud raises concerns since the fans show no branding. Also, fake GPUs with matching or identical fan shrouds have appeared in someone's video:

I believe it might be a fake too. The shroud doesn’t show any branding, which is a red flag. Also, fake GPUs with similar fan shrouds have been discussed in someone’s video (link provided). I was also checking benchmarks and the typical specs for this fake GTX 750 Ti, which the creator mentioned as around 550 Ti. Despite that, the card behaves like a real 750 Ti according to my observations. My worry is whether unlocking overclocking is possible and if BIOS settings restrict it.
