why dont you try thermal pads...

Just as a side, BMT told me specifically not to use pads.

I unplugged an old miner and promptly plugged this new, potentially damaged one right in.

......................and!?!?!?!?!?!

please I have got to know!

yeah I am waiting for:
 
1) the rest of this story

2) an update on my zen cloud miners

3) an update that my s-3's have landed in Kentucky .

The best thermal pads are not as good as the worst grease....I can see why they said not to use pads as the heatsinks were machined with a certain tolerance to be in direct contact with the ASICs (I will find out how much now when I take 1 machine apart again) pads are garbage just use a good grease and you can be messy applying it like Bitmain a la birthday cake icing style but its better not to get it where its not needed...the inside should pretty much cover the metal part with grease for optimal heat transfer ...I am about to take off the sinks from 1 of the machines and reverse the blades to see if it makes a difference..this machine went from 420ish to 400 now after a reboot

I can absolutely confirm that all of my B3 units front-side heatsinks were not anchored down properly. Burrs on the aluminum were keeping the tension springs from working at all and the screws were backed out. The HS itself started getting warm and functioning properly after reapplying. I used ceramic paste.

I can also absolutely confirm that this did nothing for my hashrate. I feel better knowing that the units are properly torqued now, but nothing about the way these units hash is heat-related, I am almost certain of this. When I had my BTCkenstein put together, I couldnt probe a part of the miner that was over 31C

Bravo Junkbarman!!!

Wish all the "stories" here had been written by you

Hey Bitmain, could you please get the documentation on chips, boards and protocol to the BFGMiner developers? I'd like to give it a try on my S3s but they say they still need documentation to write a suitable driver...

[ZiG]

Hey BitMain...

The price of BTC is BACK to $585+...OK... 

Could you adjust your S3's price back to 0.65-.66 BTC ...or lower...

That would just SUUUUUUUUUUUCK since I paid for two not 16hrs ago at 0.68 per, 1.32 total... lol.

But would be cool for the two more I'll be getting in the next day or two with luck.

you are correct they should drop price.   but the sp30 double miss on gh and on power makes the s-3  the best item to buy.

I would feel happy if it drops to .66 or .65 , but they may raise it more.


 With diff doing 2  under 10 % jumps maybe 3 under 10%   they could move price to .69 and I think it will sell.

I am looking to buy 2 more I want to see it drop to .64  I will not buy until my 2 come on fri and test well.

my s1 shows 377,278k and 775k and 120k   , my two s3's i just hooked up don't have the "k" is something not right?

I am only running one s1 blade because of power supply issues

Considering that the SP30 is almost in-line with the current S3 prices, I can only imagine how much more cost effective the S3 product lineup will be in a month from now.

Don't rush into conclusions immediately after reboot. It takes a while for hash rate to 'ramp up' after reboot.  Making a judgment after less than say an hour is quite premature (at stock).  At the lower frequency settings (212.5) it can take about 4 hours before the average hash rate stabilizes.  Then you need to check after about 24 hours, as it tends to get lower again (thermal issues?).

why dont you try thermal pads...

costs more and will cool less.

Does BITMAIN support escrow service for payments with 2x2 multisig bitcoin transaction?

For example, we create 2x2 sig bitcoin address, I transfer bitcoins to it.
So I can't use this bitcoins without BITMAIN sig.

After S3 shipment to me I release money to BITMAIN.

[Atomar]

Cost more? Maybe

Cool less?? Maybe not!! With 200+W/mK I think they do pretty good ;-)

Perhaps I should be more concise in some of my posts...in this case it was not immediately after a reboot.. what I should have said was...before I powered this unit down to move it to a different shelf it was only going down to 415 after 9 hours which is still more than the 5% variance quoted by BITMAIN..and I thought 415 was bad now I see 400 and an x after basically just powering the unit down

I check at several intervals after boot...first at 2 then 5 15 30 60 120 etc especially with new hardware and wildly fluctuating results when monitoring room temp and chips with IR temp gun etc...as noted by myself and others the hashrate drop has nothing to do with temps of anything on the unit when units that have no components higher than 31c are showing the same symptoms...
The crap firmware Im sure has a big play in this matter I just think queue of 4096, time errors of machine thinking its been up for hours and 1.5 min at the same time which can show avg of 2.3GH/s over 9 hours when its been less than 2 minutes...is cgminer process or the other miner status time conflicting when cgminer restarts?? Something is going apeshit with these miners behind the scenes...first we had mystery beeping...now not a beep at all....the silence is eerie

Which thermal pad are you referring to and buying what quantity?

http://www.frozencpu.com/products/17467/thr-178/Fujipoly_ModRight_Ultra_Extreme_System_Builder_Thermal_Pad_Blister_Pack_-_12_Sheet_-_200_x_150_x_05_-_Thermal_Conductivity_170_WmK.html

200 x 150 x 0.5 mm in size $119.99 in price. This is for 17.0 w/mK

I am really interested in what 200+ w/mK thermal pad you are referring to
