Is there any chance to get more than the 100 MHash/s out of a x5000? Can the changes to the "software" you made for x6*00 be "backported"?

Absolutely! I'm pretty sure the bitstreams are completely compatible. Could you give this one a try? http://fpgamining.com/bitstreams/lx150_125mhz.zip

Aaah! Tcl! I haven't even looked at that code before, and unfortunately fpgaminer is swamped with other stuff right now...

On the X6500, I'm using the firmware from LX150_makomk_speed_Test, with the clock at to 125 MHz. The software is completely different of course but the FPGA interface is still JTAG, just through an FTDI chip instead of the Xilinx platform cable. I don't know why that bitstream wouldn't work...

same result as thirdlight gets for me.

maybe the "core interface" or whatever changed?

can we use x6*00 software for x5000?

There are at least two different ways that different versions of fpgaminer's Xilinx-targetted code communicate over JTAG, possibly even three by now, and I'm pretty sure that the X6x00 series use a different one to the original X5000 board. You should be able to find a different TCL script that speaks the newer protocol over the Xilinx platform cable somewhere, in projects/LX150_makomk_speed_Test/scripts/ I think after digging up the appropriate PM.

Hi all,

Apologies for taking so long to come up with a response, I've been real busy with work these few months.
I've managed to synthesize a bitstream that should net you 120Mhash. It'll require further testing, but it should work. I'm working with Fizzi to get it hosted on his site, but meanwhile until that is done I could email you guys individually if you'd PM me with your email address.

Here it is: http://fpgamining.com/bitstreams/X5000_120MHash.zip

Also, I received my USB cable for molecular to test out but unfortunately ordered the wrong 2 mm pitch connector. Should get the replacement and ship it out to him soon.

Awesome!

I programmed the 120mhash/s bitstream, it runs (can't measure hashrate well, using slush).

On a side-note: I previously used a 100 ohm resistor to power the fan using 12V. It was still quite loud and so I tried 470 ohm. That was too much. It was spinning (with a little help) at first, but it stopped at some point and the fpga got really hot (could've been up to 2 days). Luckily, it survived. I now have a switch to use 100 ohm or 200 ohm, since I couldn't find a poti of right resistance.

I'm looking forward to the cable and very much appreciate your going through the hassle for me, fizzisist.

Might be a good idea to just use a lower rated fan instead of trying to use a resistor, it won't work all that well because the fan is not a fixed load, it requires more initial power at turn on to start it spinning.

I know it's not the most desirable solution, but it works well enough. The fan is glued to the heatsink pretty tighlty, too.

Hey guys,

most will laugh at this, but I turn off my fpga-miner at night because it's just too noisy. WHAT? you will say, but the x5000 original fan is this tiny screeching trouble-maker:



Now, I'm not only jealous towards all the x6500-owners for the hashing-power, but also because of their much better cooling solutions (kudos for the improvements).

So I thought, fuck it, let's cool like the big boys and try this:



Notice the yellow cable-binders I used? These also add little feet as a side-effect (sadly there are no holes in x5000 pcb).

As for the cooling-effect, well, it didn't work. The cooling block got hotter than with the old fan, very hot to the touch, after 10 mins.

So I tried this:



and this works like a charm. The cooling block is actually "cold" (well, at least not "warm") to the touch, while it was "hot" before with the small factory fan.

it's very silent (not much airflow at all). Now I can mine at night again ^^

Lets figure out how to get the X5000 working with MPBM

TheSeven wrote this when I asked him about incorporating.  It's a little above my tech level:

"Not by default, but you might be able to hack the x6500 module up sufficiently to make it work with the x5000.
Does the x5000 use the same ping assignment as x6500 FPGA0?
If yes, you should only need to remove the second FPGA discovery and instantiation."

again, Warning: this topic has not been posted in for at least 120 days.

I'm giving my x5000 to another person for purposes other than mining.

I have to look for it, but I have one. Incidentally it has a custom fan duct (made from cardboard). A photo of it was used in a BFL ad in Bitcoin Magazine, showing the photo and words along the lines of: "something like this, just better".
