Inno3D iChill GTX 780 HerculeZ X3 Ultra DHS Edition

Summary

  • It’s this one, when I got this it was very dusty and I had no idea it is actually the fastest GTX 780 (or at least in the GPU-Z database https://www.techpowerup.com/gpu-specs/inno3d-ichill-gtx-780-herculez-x3-ultra-dhs-edition.b2590). I took it for some kind of brash, lower-end model. However, I have found myself stunned by it’s great thermals and amazing core clock! It actually manages to outshine most 780 TIs on clock speed (not memory clock). I’m going to make it my new 780 pin-up!

The chip is Samsung k4G20325FD-FC03, I have some. So, will go ahead and see if we can resolve the faulty memory. Proceeding to remove and clean the faulty E1 chip pads as per Graphics Card VRAM Chip Replacement Procedure.

GTX 780 VRAM Pads Cleaned

Nice! Replacing the chip, all is well – Driver’s load, MATs passes (10Mb, 25Mb & 50Mb). Actually, things are better than fine, I love this 780! It runs so cool and kicks out a massive core clock 1097Mhz, that’s even higher than it’s stated boost clock!

Have changed all the thermal pads now, was hard to get the thicknesses right.

Under full load, the card seems to be able to stay under 60 degrees C, which is excellent for a GTX 780.
