[NAME]  FWIW, Speccy says the GTX 1660Ti in my XPS 8930 has 2047 MB of physical memory. It seems to be an old bug in Speccy that wasn't fixed. On my PC, the Win 10 Display 1 adapter screen shows 6144 MB(Settings>Display>Advanced Display Settings>Display adapter properties for Display 1) : [IMAGE] And GPU-Z also shows 6144 MB: [IMAGE] But, the commands listed at the link, above, only shows 4293 MB: [IMAGE] So it's all over the place and who knows why/how they're all different...??  
Hey - I monitor Speccy regularly as my XPS 8940 system is new. I noticed today that the GPU; NV GTX1660Ti was reported to have 2048MB memory (physical). I then checked the System tests (F12 Support Assist on boot) and looked at the GPU; it said 3MB (different than what Speccy reported). Running DXDIAG, this shows 6GB on the GPU. The MB has the Intel 630 with 1MB memory (I think). I'll have to trust DXDIAG, as I thought, based on Speccy, the GPU had 2MB memory.  A while back I checked the RAM memory speed and Speccy reported something like 1428 - which turned out to be about 1/2 the 2933 - and it was OK. (thanks for all inputs from this forum!) Seems I'm learning about Speccy readings and they are not always what they report to [IMAGE]DXDIAG[IMAGE]SYSTEM reading[IMAGE]be! Just FYI...  Scott
