Question 1

Whats the ethereum hashrate on these cards?

Accepted Answer

the ETH hashrate is from 39 mh/s to 41mh/s (origin bios);  from 41mh/s to 44mh/s (in case bios from V 64 installed).

Question 2

Hi, I removed the stock heatsink and fan and placed a waterblock on the card.
I am now noticing some coil whine when gaming or overclocking.
I'm uncertain if the noise was there before but wasn't noticeable over the fan blower.
I would re-install the stock heatsink and test myself, but I damaged the blower cables while removing the shroud.
Do you get any coil whine when gaming/benchmarking/overclocking if you listen closely to the card?

Accepted Answer

I don't notice much (if any) coil whine during gaming, but I have noticed it during some benchmarking loads, specifically ones that stress 2D graphics and computer performance such as SiSoftware's benchmarking utility (the 2D bench made the card absolutely scream). As it is though, waterblocks will typically accentuate the sounds instead of helping to deaden it since there are no moving parts and a large piece of metal works as a resonance amplifier. Will have mine on water within a week or two and I will try to remember to come back and let you know how it acts.
