HashAltcoin Blackminer F1--best FPGA miner,in stock,support hosting & shipping

[GSpgh]

F1+ costs nearly twice as much as the F1 but doesn't really have double hashrate for most algos, efficiency seems similar... why should I buy F1+ vs F1?

Honestly for longevity, the heatsinks on the old F1 are terrible compared to the F1+, thats what I believe allow the higher hashrate pulling per chip.
I believe the previous version used a heatsink per chip model with an adhesive style thermal paste where the newer is a block style heatsink with more surface area.

thanks... that's a lot of money for a heatsink though

why are they still selling the old model then if it's got a problem with heatsinks?

[GSpgh]

Because they have it in stock and it is still functional. When they die they die and they can't go as high but they still work and there is no way to remove them and reapply the new heatsink.  What do you expect them to do with them?

don't get me wrong I appreciate your explanation I just wish that info was on the site somewhere so that buyers would know exactly what they're getting

thanks

I ended up buying the older F1, why?

The F1+ was $2199 + $240 in shipping, so $2439.  The older F1 was $1,350 with free shipping.  The older F1 I could run with a spare HP server power supply I have, the F1+ I’d have to buy a $200 or so 1300w PSU, so close to $2,700, so 2x the price for not 2x the hash power.  Leaves me enough in pocket for other gear or a future update to the F1+, if and when it comes out.  Power usage was similar when evaluating efficiency, but when calculating efficiency along with price efficiency, the F1 won out for me.

Been running an F1 Mini for 3 months 24/7 no issues at all.

How many 6pins are needed for the f1 total to boot and run?

The efficiency is definitely the same as the hashing chips (the xilinx fpga) are the same exact modules, it's just that they decided to research new heatsinks and cram three hashboards in single tube miner versus the previous two hashboard and thus the f1+ was born.

Thats assuring to me that the F1+ is improved but my hopes is that the F1 is still a viable option for the price.  Having the lower cost allows me to evaluate whether a future F1+ or updated mode is in the plans for me personally with a much lower financial commitment and will allow me to either put the extra funds into a F1+, whether hosted or at home, invest in more GPU rigs, or just keep it in pocket.

I’m wondering if noise wise, is there a difference between the two?  Or is the noise attributed to the fan on the unit which is relatively the same dB wise?

Blackminer F1 mini+ is coming, You can use coupon code to get $10 discount.
Compared with F1mini, it inherits the advantages such as low power consumption and low noise.
(Power:110~120 w, Noise: under 50db )
At present F1 mini+ can support 3 algorithms: Veriblock、Odocrypt、Verus

The HNS performance on F1/F1+ has been optimized by 10~15%. Hosted miners have been updated automatically. Shipped miners could download the new bits from our website. Don't forget to change frequency of new bit to 310M. We'll keep on developing and never give up our communities!

you guys ever add Aeon to the mini+ bit list? Whats the hash rate to watt use?

[miningcoins]

Assume the 10% to 15% performance improvement is to the hashrate.
Is the power usage the same? or slightly less with the lower clock frequency?

Also Tellor has appeared in the profit calculation, but there is no bitstream for this algorithm.
Is it planned to be released soon and if so when?

[HashAltcoin]

!!!!!UPDATE on 2020/04/05!!!!!
A new bitstream TRB is released.  F1 / F1+ / F1U all support it.
Blackminer F1     Hashrate:   4.7GH/s  
Blackminer F1+   Hashrate:   7.05GH/s
Blackminer F1u     Hashrate:   9.4GH/s  

[miningcoins]

Great news about Tellor. When will it be available for shipped miners?

[miningcoins]

Thanks for uploading the Tellor bitstream for shipped miners along with the new rootfs.
Appreciate all the updates to improve ROI, especially with Handshake ASICs coming in a couple of months.

Is there a K12 Nand bitstream available?

[DanGB]

What is the best frequency at which to run the F1mini+ for Odocrypt?  Any reason to change from the default 560M?   Thanks

There is a k12 bit for all HAC products.

is there was an answer for that medium post about blackminer scam "devs stealing your hashrate" ?

if blackminer got answer to this article, can someone, please, point me to them ?
