'''Elpis''' is a 90nm [[GPU]] specifically made for retrofitting faulty [[Xenon (Motherboard)|Xenon]] motherboards. Once retrofitted, the motherboard is also referred to as [[Elpis (Motherboard)|Elpis]]. The Elpis GPU was created by slightly modifying the fixed (higher Tg) version of the [[Rhea]] GPU.

The only known change from [[Rhea]] to create Elpis was swizzling (flipping) the PCIe balls on the chip in order to match the ballout of the original 90nm [[Y1 (GPU)|Y1]] chip it replaces. Like Rhea, it uses the [[Styx]]-90 [[eDRAM]]. These chips are known to be reliable.

* Part Number: X819195
