I have two S3's, received last Friday. One of them hashes at 440GHs at stock speed (218.5), so I'm fine with it; however, the other hashes at 400 GHs at stock. I've been trying different things like putting it on a different psu's like ATX, Dell/HP server, but nothing helped. I'm taking notes on different clock speeds on this one:
Frequency GHS(avg) Temps HW Watt (Kill-A-Watt) ASIC Status
---------- ---------- ------- -------- ------------------ ----------------------
250 487.26 41, 41 2 428 Chain#2, 1 "x" on the far right
237.5 423.55 39, 37 38 367 All OK
225 422.69 39,36 7 364 Chain#2, 1 "x" at 2nd position & 1 "-" at 8th position from left
218.75 403.58 40, 38 0 355 All Ok
After editing the asic-freq file, a reboot command was issued. All readings were take at 30 minute mark. PSU is a Dell Server Power Supply 750W. All 4 PCI-E cables are plugged in, even at stock frequency.
Yes, it took me over 2 hours to finish writing this post.
I'm setting the frequency at 250, seems to be the sweet spot for this S3.
At what frequency would you run this at? Why?
