i upgraded to a 2000W and overclocked to 1100GH
What frequency setting for 1100 ?
Im running 215.625MHz (any higher was >1% errors) and the S2 says 1100GH average but pool says 1068GH average.
doing the math now, its current error rate is 1.06% so i may need to tune it down to 212.5MHz
Thanks. What are reported temps ?

just a heads up - its only been 36 hrs but swapping the 4Gb class 4 SD for an 8Gb class 10 seems to have stopped the daily beepings.
so yea, saving a dollar per rig on cheaper SD cards causes miners to suffer untold downtime - must be worth it.

Well, look what turned up in one of the S2's I ordered today!
I'll open it up tomorrow and get a photo of it.
This was in dmesg, for anyone who's interested

I have lots and lots of S1 and S2 coupons available. Contact me ASAP if you want one or more because the S1 coupons expire May 29 and the S2 coupons expire May 30. Just PM me your Bitmain ID and let me know how many you want of each.
They are free for the taking, although tips are appreciated:

Thought I'd post an update on my unit, been rock solid. As always if anyone has technical problems, please post in the help thread.
i upgraded to a 2000W and overclocked to 1100GH
What frequency setting for 1100 ?
Did those of you that upgraded after running the provided PSU for a few days notice a boost in hash rate after the upgraded PSU?
I replaced the PSUs in mine from the getgo. Didn't see a point in waiting for the PSU to under perform or die.
One got a 1300w, another got a 1200w.
Now if I could just get it them to work at full capacity with p2pool.

has anyone attempted upgrading to a new 1300 Watt PSU?
I upgraded to an old Enermax 1350. Had to stuff the braided cables through the hole where thelittle fan used to be. Runs excellent!
Bitmain should really change the pricing on the S2's to BTC price not dollars. These miners should never go up in pricetag, that's bad business.
Fix it to BTC already with steady decreases. They'd get alot more buyers that way. Also, the S2 has been out for awhile (since early April), no reason for it to be over $2k pre-coupon at this point. No chance at ROI for miners at this difficulty and future ones. It'll never earn back the 4 BTC it costs.

Even with a coupon it won't earn the 3.3 BTC asking price - needs to give a little here...

Any update on price bm?
[edit] please don't tell me it's UP again...

2309 or
2309-400 = 1909 if you have a coupon

I put EVGA1300's in mine and get 1148 @ 225 Freq. HW Errors are super high, but it does increase W/U by 2000 or so.
I've got EVGA 1300 coming, might try it in S2 instead of 3 ants as I planned. So, what % are HW errors? Sorry, what is W/U? measure of work done?
has anyone attempted upgrading to a new 1300 Watt PSU?
The S2 stock PSU is 90% efficient at around 100% load. If the PSU is drawing 1100WAC at the wall, then the S2 is pulling 990WDC (1100WAC*0.90) from the Enermax Evolution 87+ 1000W PSU. Its specification states that the maximum total output of the 12V rails is 996W (83A). That makes it a whopping 99.40% (990W/996W) load being exerted on the PSU. But wait a minute. According to the actual 80 PLUS Verification and Testing Report, the PSU only puts out a cumulative output of 74.4A at 12.10V (900.24W) on the 12V rails at 100% load. Therefore, the stock PSU has a deficiency of around -90W (900W-990W = -90W). So, where's the S2 gonna get it from? This is why they have been failing.
A 1300W PSU is no doubt more suitable. It'll get around 76% (990W/1300W) load from the S2. A 1200-Watter would be around 83% load which is still acceptable.
