"Factory Hot" USB Erupters on rPi MinePeon?

[AnatomicFlack]

I just got my blue erupters in the mail today and got them hooked up. 

After a couple of reboots and spreading them across two d-link hubs they are now all seen and working.  The errors seem to have slowed way down after getting the units up and running.

My question is that two of them appear to be running at about 650MH and the rest at the advertised 333MH. Note the clocks on ID 6 & 8.  The BFL is a 30GH Single.

Is this normal, did I get a couple hot chips or is this more likely just a reporting issue with MinePeon?

What does your pool say ?

I have had similar, I think it is a querk in minepeon.

Locate the relevant usb's and try them in your PC to confirm.

I just ignore it.

I was just assuming misreporting of the speed since those units aren't mining any faster according to the stats, and in fact are performing a bit under the rest.  Didn't stop me from thinking I scored big time for a little while though!

As far as the pool report and the report from MinePeon, there is a pretty sizable gap:

MinePeon: 30702.526
Slushs: 24054.458

Is that much of a discrepancy normal?

there was still a gap when I was only mining with the BFL... I believe I was reporting around 27K, and Slush was reporting around 21K. 

I'm in the midst of building an Ubuntu setup on a old MSI Wind Nettop PC (Intel Atom 330) I had laying around.  I was originally setting it up to run the proxy for use with my Erupter blades on the way, but I'm thinking I may also move the USB units from the rPi over to it and see if anything changes.

The hashing speed is derived from the clock speed going into the chip; for the BE USBs, the clock is provided directly by a crystal on the PCB. This is how some people have overclocked their USBs - by replacing the crystal with one that oscillates at a higher frequency.

So unless those two erupters have crystals running at 2x the frequency of the others (the ASIC chips require substantially more power to run that fast) it's probably just a software reporting error

Hashrate is calculated by the work returned.  Its probably just a lucky streak, let it run for a day or so and it will trend to 336.

I have 100 asic erupters on three Pi's with Minepeon.  On occasions I well have 1-3 miners report 666 instaed of 333 hash.  I think it may be from minepeon, not sure.  The pool stat is 333 no matter the peon report.  If the hub is low on amperage you well see weird speeds.  I started with the d-link, they suck, get the Rosewill 10 port hubs, they run 8 sticks and a fan.
