X6500 Custom FPGA Miner

[kdbaumann]

I am trying to get mpbm working with a X6500 rev3 to connect to slush's pool.  I can't seem to do it.

Thoughts?

So now that difficulty is going through the roof and many of us either have ASICs or will soon have an ASIC, soon it will make little sense to continue mining BTC with x6500 boards. Once difficulty hits 100M then in my area a x6500 is only break even with electricity cost...

What do people plan on using their x6500 boards for? Are any specific alt coins compatible and worthwhile?

many of us have ASIC, you mean many of us have asic erupter miner. some are waiting to receive their device and just a few have a real ASIC.. from altcoin, maybe nanocoin or wait until scrypt have been ported to lx150...

Anyone have a good write up for getting either CGminer or BFGminer to work with the X6500 on windows or linux. I can only get them to work with MPBM atm.

+1 Somebody has drivers for CgMiner please!!!
Thanks!!!

I am going to continue to mine with them for the foreseeable future, even when it goes against conventional “wisdom”. These devices take such a small amount of power to run that I will switch it over to solo mine and run a dedicated btc/tor Raspi node.  This will be a form of Lotto approach, even if I don’t hit a block for many years oh well  and if I do I will have virgin coin.  If somebody comes out will a really good low power ASIC I may replace it but the current landscape will need to change and prices go down dramatically with availability way up (1year or so maybe less is my guess).

I laugh at everyone who always thinks they are so smart with their profitability projections. If I listened to these geniuses I would not have been mining when BTC was under 0.50$ because people were saying the same thing back then.

And the "ASIC is almost there" I'm reading here since end 2011...

I assure you they are definitely here. Now with multiple chip makers with a working "recipe" (Avalon/BFL/Bitfurry?) it is going to be a race to the bottom.

[vpereira]

some of them are here, some of them still having problems to delivery.. I know that until mid-2014 I'm still able to mine BTC with fpga, then we will be able to reuse the FPGAs to mine another SHA256 altcoin or reprogram our xilinx6 to do some scrypt... in almost all threads there is somebody trolling with this argumentum ad asicem  "buuuh ASIC is coming". it is just bo ring..

the DIY ASIC thread remembers me pretty much the Open FPGA thread, back in the days.. its great, but not for the average miner, looking for usb miner... the K1 is a nice one, but it will be available in september or october.. maybe it will be already to late..

I am running an x6500 with bfgminer 3.10.0 with bitstream "fpgaminer_x6500-overclocker-0402.bit".

It default starts at 190Mhz per processor and jumps 2Mhz up every minute or so until it hangs at about 222Mhz per processor. Is there a way to lock the clock rate of the processors? When I [M]anage devices and set both processor clocks to 200Mhz, it continues to increases the clock by 2Mhz every minute.

Any help would be greatly appreciated!

Are other versions of BFG working for you? I am still running mine on 3.9 and the OC firmware. I don't think you can use the set speed firmware with bfg (I think) and cg didn't want to support if for some political BS as far as I could tell, this is a shame since when I used the fastest set rate firmware it ran with 0 errors. Overclocker runs slower on some chips and a good amount of errors (higher than 0). TML was the best way to run these but was linux only.

With cheap USB sticks doing 1.5-2.5Gh I am about to pull the plug on the x6500 and perhaps use it as a toy to mess around with (probably won't get around to it)...

bfgminer 3.10.0

you can add --set-device x6500:maxclock=XXX i believe that is the correct syntax

I took offline my two FPGA a long time ago, but I am now wondering if they can be used for altcoin mining? Any guides or suggestions?

check out kramble's LTC mining code.

[bhai]

yep that works.

I get 70Kh/s with my ztex 1.15y.

rgdz,

my search fu fails me.. could you provide a link please?

Never mind.. google found it for me..

This is interesting.. Does anyone have scrypt bitstreams that work on X6500s?  From what I've read, work on porting this to x6500s was stopped late last year.

Hello,
I see no one's posted here since last year...
I recently decided to look into FPGA's again to see if anyone had managed to produce either a DIY or commercial version.
I saw the X6500 guys tried and probably sold a few for mining SHA-256 when it was still viable but that petered out pretty fast during the last 'adjustment' - crash! ...
Since then, has anyone been interested in or looking to re-program the X6500 for Scrypt mining or will that make the chips too power hungry much less capable of hashing at a decent / profitable rate in the first place?
I see the flgamining.com website is still up but there doesn't seem to be any activity since they announced shutting down the operations way back when.
Such a shame too. I really like their design. I mean 400MH/s at less than 15W is still efficient.
I'm still mining Scrypt with my5 chip GridSeeds since electricity is included in the rent . They even still make me a whole dollar per day sometimes!
Anyone know of any new FPGA designs in the works or available for us DIY techy's?
Peace!

Maybe you can use it to mine blake256 algo
