"Zeus scrypt chips software implementation" doc http://zeusminer.com/user-manual-ver-1-0/
From the doc we know the chips have 8 cores.
Also it indicates the hash rate is approx 70% of the clock rate if "--nocheck-golden" is used.
So 340 clk would equal 238kh/s per chip x 6 chips for the Fury = 1.4mh/s approx
328 clk would equal 230kh/s per chip x 6 chips for the Fury = 1.377mh/s approx

In the formula from the datasheet, R7 is th resistor I have swapped, R8 is just under it on the PCB with 93A marking
R7=0.591xR8/(desired voltage-0.591)
5.6K gives 1.57v
6.2k gives 1.48v
6.8k gives 1.4v
7.5k gives 1.3v
8.2k gives 1.26v
I measured a bias of +5% on my board. I haven't measured the R8 out of the board, but if it's slightly out bu 4 or 5% it could be the reason.
1.65v
for undervolting, if you want less power draw
10k gives 1.14v
11k gives 1.09v
12k gives 1.05v
13k gives 1.01v
Changing the R8 will also work
don't touch the 9.1k one, replace the 93A labelled one
10k gives 1.24v
11k gives 1.30v
12k gives 1.37v
13k gives 1.44v
15k gives 1.57v
for undervolt
6.2k gives 0.99v
6.8k gives 1.03v
7.5k gives 1.08v
8.2k gives 1.12v

Readcount Timeout is explained as:
Quote
4.3 Readcount Timeout
After we send one command packet to the chained chips, that BIG chip will cover all the 32 bits nonce in a certain TIME. So we must send a new work to it before that, otherwise its hash power is wasted.
Cgminers readcount timeout is used for that. Every count means 0.1 second. We now set the readcount to be 3/8 of the covering time. It may be 3/4 later.
