Topic: Bitmain Launches the New Antminer T9 Bitcoin Miner - page 11. (Read 38836 times)
o boy and that is biggest ASIC manufacturer in world. If that comapny would be in EU or USA. it would have been shut down alredy, assets stripped, property confiscated.
I received a T9 with what seems to be a defective fan. It starts hashing and soon it overheats. One of the fans does not go above 1900rpm.
We went ahead and purchased 15 R4's and 20 of the T9's for our own operation. We will keep you guys updated and post some pics when they come in hopefully this week!
T9's and R4's have been since Friday/Monday! Here are a few pics of them 
http://imgur.com/a/vYxSjLooks great. My question is why would you buy R4's for a datacenter installation where noise is not an issue? The cost per gh on the R4 is 30% higher than on an S9.

Just lit up a pair of T9 on DPS1200 PSUs. Meter estimates 2850W for the pair and one-hour reading of 23.43TH between 'em for an average of 0.121J/GH.
yup really looks like reliability is finally fixed. Instead of trying to push to limits and then dying like flies
Ah the time frames of Youth...A few miners with a few days of run time on them does not equal better reliability than a s9. Most folks have zero trouble with the s9's at the start (and minimal issues during its lifetime). Out of the 16 s9's starting from batch-1 that I have, only 2 bad boards to date.
At least give them a week, preferably > a month and THEN make that call... Now better than the latest R4's -- based on my 1 bad out of 3, so far I'll give ya that one.

Here's a video I made today showing comparison of T-9 11.5 vs. S-9 12.0 variable frequency power draw at the wall. Uses more power, but runs cooler.
At 210 VAC
T-9 uses 1352 W, hashes at 11.5, highest chip temp 80C
S-9 uses 1329 W, hashes at 12.0, highest chip temp 94C

whats is you room temp ?
and S9 batch ?
because latest batches have less temp than earlier one
I have just watched this miner. I feel very impressive with this batch of antminer.
I will buy it in next month after I got my salary.

Thanks for the video Jack. How strange the S9 is using so much more power than the stated specs on the web site. I think they quoted something like 1079w for the 12th S9 so that is significantly above the spec.
Really looks like the T9 may be a winner then just based on the cooler temps and the power use looks like it isn't as bad as was stated in the spec for that unit. Good to know! The T9 may turn out to be a good unit! Please keep us posted.
Well, in the first video I made I compared it to a 550 fixed frequency S-9 at 11.85 TH. The older 550 speed S-9 used only 1178 watts. I think when Bitmain changed to variable frequency they didn't update the specs on the S-9

sick miner as always!
I have been running 10 X T9's for 7 hours now. Cool and stable.
On another note. I have already lost 4/10 R4's from my friday delivery. Awesome.
Bitmain said they will cover shipping on them though. We will see how that works.

The 3 T9 units now have 8 hours run-time on them. All performing at or a little over stated hash-rate.
Temps appear to be nice and stable. Fan noise on par with the S9 i have beside them.
So far so good.

Yee looks nice. Good luck with miner.
Thanks for the Update. Does anyone else have any early experiences?
My T9s arrived earlier today and are all up and running nicely. No problems to report so far.
sat on the shelf beside my S9 with its 76d3h38m32s uptime
Il update if anything changes.
