just got mine hooked up

PCB temps 57, 57, 61

Chip temps 77, 79, 84

running at 525 AVG 729 gh/s

52   69
50   66
56   78

569mhz - 787ghs

I turned down the frequency because I've lost 1 S9 board before and 1 avalon board

so with your temps I would get some kind of better air conditioning or venting

temps have normalized after letting run for a bit to this

pcb - 57, 58, 63

chip - 68, 70, 77

FANS ARE SUPER LOUD

Fan 1 - 5,910 Fan 2 - 5,190

anyone know of a simple sound proof setup that doesn't require venting air outside?

It is better to extract to exhaust air to the outside, it is much cheaper than aircon. I use 6" ducting

yea thats what I mean by 'venting' Wink

looks good

Based upon what I've been reading across multiple threads, if you own one of these, I would definitely underclock it unless you got some amazing cooling in front of it

Under clock by how much?? Any ideas? I am about to leave town and don't want this thing blowing up. Anyone have a good setting to put it on?

On default setting (600) it seems to be overclocking. I'm averaging over the stated 815, but also getting a lot of HW errors and chip temps seem high especially since L3+ says keep under 80 C. Any suggested settings would be helpful.

Wow, still really hot chip temps even at 525

Can it be set any lower?

Those are good temperatures right in the middle of 40-80 limits.

Plus, at a certain point, the only way to lower the temperature is having the surrounding air in the area cooler.

If Blissz comes out with a a3 firmware you can lower the voltage which will drop the temperature easily 10 C

Anyone know if Nicehash is planning on allowing A3's to mine with them in the future?

NH said it should work but don't know why it is not working

Someone posted that they would not be allowing A3s.... Not sure though if they changed that statement

SIA Core Team announced yesterday they will not be invalidating the A3 Asic unless Bitmain does something to hurt the network.

I have A3 directly 50 cm from the fan and my temps are:
PCB Temps => 49, 47, 47
Chip Temps => 62, 71, 72
But I also get like hundreds HW errors per day.
And I'm hashing on average 831 Gh/s.

Anyone seen the pool stats? Im getting half the payouts today on siamining. Anyone getting good payouts in nano or elsewhere?

Edit, found the link in previous page about updated pool stats, the website I used had bad info.

Can anyone with an A3 tell me if they are seeing a lot of hardware errors? Is it normal? My L3+ has run for 2 weeks with only 1 HW error. The A3 is in the thousands just overnight..

yeah same here, i reduced the frequency to around 525 mhs

What hashrate are you getting with 525 mhs?

My A3 is set to "default" setting. What is the normal frequency for the A3? Also when is warranty voided if you wanted to overclock? Anyone know?

waranty is voided, speed at 525 is around 780 ghs but shows 700 at the pool

the defaul its 600 it shows on the main mining dashboard next to the temps. What are your chip and PCB temps ?

Ah yes I see frequency on main page now.

PCB Temps => 58, 58, 62
Chip Temps => 74, 84, 87

Avg Gh = 834.51 (15 min since I updated settings)

My Sia Output: https://siamining.com/addresses/05fbb51de819d9e60c3e24c239f23ad59cb022de4a1933e62844f6fc99c9e4bedc4ca686322b

what you are getting 834 with 525 freqency ? your temps are alot better than mine

834 with default setting which is 600.

oh thats the same here, I dont like chip temps over 83 so i downclocked both mine

Mining with noise and without noise is all possibl

Anyone in Singapore want to get one A3, I am considering letting go one of the unit expecting shipping next week.
