Hi I have received two units of S9 and both have one board hashing around 2.7

They are batch 2, is it a normal? Any tips?

Thanks!

As others have said try lowering the freq. I have one board which underperforms as well. If I do a 'save and apply' without changing anything, sometimes it will come up good (higher hash) and sometimes it will come up bad (lower hash). But lower freq usually means better odds of it coming up good when I restart cgminer. I can tell within a minute if it got a good start because it will either come up past 3000 or it wont by that time.

I've got it working with the mysterious "low voltage" firmware from June 22nd. I had to lower the frequency to 593 and reboot quite a few times but now I got it running at 12.6 TH stable, with the slow board around 4000Gh, I guess this is as good as it gets.
I'm wondering if using an alternative PSU to my bitmain one would improve, I will try to borrow one to test.

Heres what my B3 reports....

Code:

Chain# ASIC# Frequency GH/S(RT) HW Temp(PCB) Temp(Chip) ASIC status
1 63 600 4263.66 2 61 91
3 63 600 4278.41 2 63 95
4 63 600 4311.41 5 62 94

Is the low to mid 90's correct operating chip temp on the batch 3?
I've got a batch 3 coming this week.
Thanks.

Its warmer than I would prefer, But ambient is 30C right now

Thank you. I was just wondering what temps I should strive for with the S9B3.

So I went to bhphotovideo.com and preordered

2 msi rdn rx 480 8gb gpu's cost a lot less the 2000
used a cc have a 3 year msi warranty and earn points with my cc....

this is the only competition there is for bitmaintech at the moment.

I was considering it but the ship date that they have listed worried me. I just hope it's a filler date they put into the site.

i have done business with them they are decent.

so i will await news from newegg
i will await news from provantage.

i look at all the gear and I have 8500 worth of btc miners

and while i have 5 pc's that can hold 15 video cards I have no video cards so now I at least have 2 on order

Are you talking about for ether mining?

I thought you already built a couple ether miners.

I sold all the cards to prep for the new model cards. the pc's- mobos are all empty.

but they fixed the error on bitmaintech site so I grabbed the final s-9 the array will be ready for its sixth and final miner.

the tx id is confirmed.

my fifth and final s-9 should be here by friday I hope.
