Re: [computer-go] question regarding Hydra Chess PC computer

I am interested in the topic of overclocking, how well do FPGA's overclock?
Can you use liquid N and get double the speed?

No idea. The Hydra Cluster is placed in Abu-Dhabi. One of the hottest places
in the world. We are already happy if we can cool the system to normal
room-temperature.

If I understand this correctly, you can stay within specs and have a max. 2x speedup..

One crazy idea would be to modulate the voltage, higher voltage would
give some extra speed boost, but would also stress the chip. If the
speed is only needed at very low duty cycles then the stress would be
I think you gain some speed without leaving the legal ground of the specs.
Turn up the core voltage to max (+5%)
Cool the device down to -40 C.

This may give ~ twice the speed of the usual worst case calulation used for
static timing analyze (+85 C, -5%)
