Sapphire Batch USB ASIC Miners not hashing at full speed?

[n4ru]

So I recently received 9 miners, the standard hub and fan setup. But apparently I'm mining at 2.87GH/s when it should be at around 3. I see several miners hovering around 266 - 300 MH/s. Does this average out or am I slated to continue mining at this rate?

you are using one hub for 9 USB miners?  what hub you are using, that might be the problem try 2 hubs.

Anker, the high powered one everyone is using.

I have about 15 of these, and they mine around 333mh/s.  what miner software are you using?

I'm using cgminer 3.1.1 under various flavors of windows with 2 anker hubs.  If the miners are performing sub par, I'd look at the host system (CPU being hogged by something?) or the hubs.

5A or 4A PSU?
Check on the back of the brick.
