Yesterday i received my SC 25 gh but it is only hashing at 20gh i know it is not worth RMA it at this point any idea if it can be flashed to achieve higher hashrate? Thanks Title: Re: BFL 25 gh help with hashing!!! Post by: sebdude420 on November 13, 2013, 10:37:47 AM Same boat here. Order 30ghs got 27ghs. Bfl fucked us all really good and hard.
Anyone got good idea on LS fix for this type if issue or common problem to check. Thanks. Title: Re: BFL 25 gh help with hashing!!!

Thanks Well that's ironic. Exact same story here right down to the delivery date. Title: Re: BFL 25 gh help with hashing!!! Post by: ryanb on November 13, 2013, 06:29:13 PM Same boat here.

Title: Re: BFL 25 gh help with hashing!!! Post by: RW02 on November 13, 2013, 11:29:41 PM there is a small trick you could try it gets a bit extra out of them but dont expect a miracle
unplug the unit and place it infront of a desk fan keep rotating it every 2-3 mins for about 20 mins untill its cold then plug it back in you should see a small improvement in speed id offer 0.5 btc for it :D Title: Re: BFL 25 gh help with hashing!!!

Thanks Sell it would be better, and buy better ASIC which is about to come... Title: Re: BFL 25 gh help with hashing!!! Post by: MarketTime on November 16, 2013, 04:44:18 PM Same boat here.

Thanks. did u try overclocking it? how do you overclock it? I am not too sure about BFL product but some ASIC come with instruction on how to over clock... Title: Re: BFL 25 gh help with hashing!!! Post by: tel on November 17, 2013, 04:16:05 PM Hi,
1. Try to update the driver, 2. Try with another mining software /bitminter, cgminer etc/. 3. Use another power adapter. 4. Increase the fan speed Title: Re: BFL 25 gh help with hashing!!! Post by: ryanb on November 17, 2013, 07:13:58 PM yesterday it dropped from 20gh to 17
now it is only hashing at 17gh i updated bfgminer i am running it on raspi Title: Re: BFL 25 gh help with hashing!!! Post by: ryanb on November 17, 2013, 11:14:23 PM i fixed it guys
i opened it and removed the heatsink and reapplied thermal paste and now it is hashing at 24gh Title: Re: BFL 25 gh help with hashing!!! Post by: HotSwap on November 24, 2013, 08:52:59 AM i fixed it guys Out of curiosity which thermal paste did you go with?i opened it and removed the heatsink and reapplied thermal paste and now it is hashing at 24gh Title: Re: BFL 25 gh help with hashing!!! Post by: clicksmoney on November 24, 2013, 09:31:12 AM Out of curiosity which thermal paste did you go with? I really doubt whether it really matters what was applied - even toothpaste would have been more efficient than the heat transfer the material that was there was providing. ::) Generally IC-Diamond 7, Arctic MX-4, Arctic Silver 5 are the best we have unless there's blackops stuff around.

Post by: lightfoot on November 24, 2013, 06:41:31 PM Nice job fixing it. Question since I am tormenting a poor little jally right now: Do you remember what the temps were, and do you have one heat sink or two in your unit? Did it have all 8 chips on there?

Did it have all 8 chips on there? i also did it on my jally i have the upgraded one and it was hashing at 5.5 did the same thing opened it and now hashing at 7 ghash the temp on jally was 40 now it is 45 and the LS was at 50 now its at 60 so that is another sign that the heatsink contact was not right Title: Re: BFL 25 gh help with hashing!!!
