333 to 336 however these DO need active cooling to keep hardware errors down.

Greetings.

I'm getting for my 2 USB Gizmos, 336.4 to 336.8 MHash/s, also with active cooling, 1% Hardware Errors.

The ASIC chip needs a heatsink and the best I saw (and going to buy from Taiwan in a few days) is the smaller of a 3 heatsink kit to the Raspberry Pi, intended for the voltage regulator of the RPI: http://www.ebay.co.uk/itm/171047859890?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

If anyone knows a better one, please post here.

I believe the heatsink that's on it is glued to it so be careful you don't wreck the chip removing the old one

If you are talking about the USB block eruptor, the heatsink is on the backside and it falls off when unscrewed.



The thermal pad is not sticky.

With a fan on mine, they are averaging ~354MH/s each.  It does fluctuate quite a bit, but that is the average.

How are you getting 354? Any modifications?
Also is it better to take of that heatsink? I Have two of them and for now they are with heatsink on with 120mm fan blowing on them, all i can say that they dont get so hot like without fan, exact temps cant tell, but without fan it was 66 C, now its a lot cooler, but i still get ~ 1.9% HW.

I dont think active cooling is neccessary. I got three Erupters and I found out that a passive chipset-cooler attached to the initial cooler along with this thermal-pad does a great job. Got a picture from my setup here:



Soon each Erupter will get bis own chipset cooler.

The idea is to keep the original gracious heatsink with the BTC logo at the bottom side and glue the aluminium heatsink directly on the ASIC "BE100" chip with the included 3M Self Adhesive Thermal Layer, at the upper side.

My BTCGuild estimated speed is 1,760.94 MH/s for 5 units, which works out to ~352MH/s each. I've also got a fan on mine.
