the default is 282, and hashrate is 60G.
Does anyone tried to set it to 300?

yes. i've been running that way for a while now. i think xiangfu said it should not be a problem.
would be nice to know if we can go past 300 though.

This is not a video card or CPU you can replace by overnighting one from Newegg if you fuck it up.

Good point. I was curious about running it at 300 (not a huge "overclock" over 282) but I don't want to chance it. I'd also think that power consumption will naturally go up and that poor Antec 650 PSU is pretty much almost overloaded. If I had watercooling blocks for the Avalon units and a beefier PSU then I'd feel more comfortable upping the clock rate.

What hash rate are you getting at 300MHz?

Another thing is I have one avalon hashrate at 65G, another only 55G.
Both 282 mhz.

Someone else mentioned on a different thread (can't remember which one) that if you set the clock to 300 the hashrate bounces all over the place from 60 to 80 GH/s. Can anyone else confirm this wild fluctuation in hashing rate and what would be the average hashrate for an Avalon clocked at 300?

I believe if you can provide a efficient cooling. overclock at this level is acceptable.

I've been running at 300MHZ for a couple of days (in an air conditioned room). It seems to give around 71GH.

I tried mine at 300 for about 20 minutes. The hash rate and the shares submitted didn't change. So I put it back to 282. My unit was in a cold room, 0 C. The thing is running so well that I am loath to mess with it. I have a better spot to put it but I don't want to turn it off.

How about your hashrate at 282Mhz? it's very strange 1 of them is only 55, while another is 65.

282 --> 65 (590W, 220v) 300 --> 71 (640W, 220v) i am running it stable at 300 without problems although it is a bit loudy i am not sure about PSU, i haven't opened it, is it really 650W?

thanks. I just tried with 1 avalon, it's 66G -> 72G . looks stable. the temp is 42 -> 44 and fan 1260 -> 1960

I think a good investment would be to put it on a UPS. I got my eyes on a 1500VA unit - should be more than enough juice to keep it mining during brief power outages.

Hmm extra 50 watts for 300. I guess that will for sure overwhelm the Antec 650 watt PSU if one runs at 120v. I don't think I will try this until I slap on a 850 watt or 7500 watt Gold or Platinum rated PSU.

Are you running the latest firmware? And this happens no matter what clock rate the chips are running at? What do the temps say? Are the fans spinning at above 1000 rpm and can you feel the air flowing?
