Note --set cbm:clock=xNNNN will also work; you just need to abbreviate it "cbm" and can't spell out "compac".
(That's what is being fixed in 5.4 - being able to spell it out)

I was unable to get --set cbm:clock=xNNNN to work.  I believe you said you used it on the pre-production stick that was sent to you, but I cannot duplicate your success on the production stick.

Nice, i have one customer that was running BFG and switched to cgminer because somehow he couldn't attain more than 12 GHs with these sticks. Is this a known issue, or should i debug it further?
There have been a lot of people mentioning they can't figure out how to set the clock and whatever they type in, it goes to default instead. The new version where you just type in the actual MHz should be pretty foolproof and awful dang handy.

Yes, it's a known issue and I have brought it to luke-jr attention in the bfgminer thread.  The command line frequency adjustment will be fixed in 5.4.0 as he noted and as a result of that discussion, but in 5.3.0 the compacs will only run at "stock" 225 setting.  A work around it to use RPC's pgaset and set the frequency that way.

1) Start bfgminer and your sticks via command line like normal, but omit the frequency setting command.
2) Once running, open another command line and navigate to your bfgminer directory.
3) Input the following:
Code:
bfgminer-rpc "pgaset|0,clock,x0982"
4) In the above command, the "0" refers to the position of the miner in the list in bfg.  If it is at the top of the list it is 0, second down is 1, third down is 2, etc.
5) Replace hex code at the end with hex code from first post in this thread for the freq you want, omitting the leading 0.
6) Hash away.

Feel free to copy/paste any of this into the first post of this thread until 5.4.0 is released.

Also note that BFGMiner 5.4 will support setting Compac clocks as the MHz number directly.

I have no problem getting 15 Gh/s myself.

AKA, debug further. Get the latest BFG, set just the MHz number, see if it works, don't forget to add a little more juice to compensate.

I was getting 15GH/s out of the box myself. I was running in stock CG with a OC'ed U3, so I wasn't sure the numbers propagated to the GSC (both were running at 250MHz/0.875V according to CG)

Note that for bfgminer you have to use the hex value for a given clock rate, whereas for cgminer you specify the clock rate in MHz.
A table of values to use in BFGminer is as follows:

Per discussion with luke-jr in the bfgminer thread, the leading 0 should be dropped from the hex values in that list in the first post.
Sounds like the "leading zero" is your problem.
There was never any expectation/support for one.
How can I improve documentation to make that clear?

sidehack, what do you thing a peltier would do? 22 watts of cooling capacity. cool the power section and chip. I would need frost precautions etc but I can do that easy.

stupid? oh yeah that has vapourminer written all over it. I mean anything worth doing is worth overdoing as the saying goes.

ive only known +50W peltiers to go below 0 degrees Celsius, i've been playing with a 40mmx40mm, that runs at 15v 7A for best results, cant get it lower then 7 degrees lower then ambient, off a sink..

what about novec, anyone wants to drown these babies?

only if they are in a fish bowl, with an IP cam on them, sinkless Cheesy

what is this "brake pedal" you speak of?
Peltier is a lossy cooling method, if I'm thinking right. With a bit of beefing on the power systems we pushed a stick to 488MHz off the stock heatsink and about a 1.5cm square stick-on on the back that probably wasn't doing much. But if you could pull that much heat out of the ASIC you could get some serious speed out of this guy. Probably have to replace the inductor with something that could handle more current, and make sure your bus voltage stays above about 4V or your power will be unstable.

it is lossy. cant remember the loss percentage offhand

hmm i can see a hot air rework station in my future. although a temp controlled iron i have could probably do it.

which inductor do you recommend?

Still getting:

Miner has been running solid for 24 hours now, pretty neat little miner!

cgminer basically does Zadig for you automatically on Linux. It's still ugly behind the scenes.

It might be ugly but if it get's the job done I'm happy.  Windows is ugly and does not really work all the time. Some are lucky and they get Zadig to work first time.  Others its a pain.

I love the compac-cgminer.  It works great on RPI.   Weather it's code is ugly or beautiful it just works great.

getting this  alot, only at about 800MH/s - 1000MH/s

*Edit*

DAMN, moved USB ports blamzo, 8-10Ghash.

Glad to hear it's working.  Not all USB ports are equal.  This is why a nice powered hub is nice to have you know what electricity it has.

With windows moving also might have did something with drivers and helped.  The zadig drivers in windows is why I like linux so much.  If your doing it long term look into RPI with a powered hub. Not only is it easy to setup but it cost almost nothing to run.

I have been meaning to get a raspi for mining and messi g around with, do you not need to install drivers on ubuntu? I put the zip file for the cg miner on the comp but i dont get how to run it lol.

No that is the nice thing is it works great.  No messing with drivers like windows.

So that is why I refer to it.   If you get a RPI you will be very happy for minera or running it on a desktop on RPI.

Should be the same as these (may need to add a few packages).
