Yea. The spikes are quite real.

has anyone tried the new driver?  AMD Crimson ReLive 16.12 its now available for download
i hope there's improvement in our hashrate

stock clock rx 480 8 gb = 240 sol,
210= undervolted to 0.9v and consume around 105 watt at cm version 9

One of my pc's has a 730w psu powering a rx 480 and a 280x. This combination has been running stable for months without problems (even eth/sia dual mining). A few minutes ago, the pc rebooted and said "a power surge was detected - press F1 to continue". There is nothing else running on the system except claymore v9.

not a single hash extra but we got skype performance enhancements

there are crashes often leading upto the donation mining portion of mining which makes me wonder if some dual mining mechanism isnt triggered during the donation period which is more taxing on the system.

how old is your power supply? did it you manage tog et up and running again without issue?

Nope, 650 at wall. 650 on power meter.
System uses about 80 watts, so cards eat about 115 each at the moment.
It up since v9 came up, why should it fail ?

All depends. That typically can make a difference if you're not using risers. Also, you might want to install HWINFO and check the ASIC quality (it does make a difference for ZEC, you can push that card harder).

Of the two official link for towing v9.0, that of MEGA-so now is a file that does not have the same volume in KB, as the file last night .... it "the hour of modification" of ZecMiner64.exe is different from the first file last night ... even though it is older, it may not matter that it was "earlier version" of the "official" ... if you have problems with the stability of the machines, etc. . after updating to v9.0, it might be a good idea to try the "unofficial version" ...

Why Claymore silent and says nothing about the replaced files?! ??!
