Ok Here goes

F6a
20x190 Turbo enabled
QPI x36 = 6.84GHz
Uncore Auto = 3800MHz
Isochronous support enabled
performance enhance STD
Multiplier 6 = 1140MHz
DRAM timing Auto - this shows 7,7,7,20,1T in BIOS
CPU-Z shows FSB : DRAM 2:6 8,8,8,22,1T
LLC Disabled
VCore - 1.425
QPI 1.395
IOH 1.100 AUTO
DRAM 1.5v AUTO
QPI Pll 1.14v
Dram termination 0.75v AUTO
CH A,B,C Data V Ref 0.75v AUTO
Ch A,B,C Address ref 0.75v AUTO

Tried to manually set Dram Volts to 1.64 and timings to 8,8,8,24 which is where the memory (OCZ Gold 1600MHz) was rated for 1600MHz operation, left everything else the same. This didn't work so tried Uncore at 17x and 16x as you suggested, neither worked

So with turbo enabled your actually getting 21x190?
qpi and uncore look fine, you could actually lower your uncore some I think down to x13 even.
Running things on auto is sometimes not a good thing in that you end up letting the mobo bios decide important things for you.

You might want to learn your default v's and set them manually, same with your qpi and uncore multi's and also your memory multi and timings.
That way you're not guessing at what the mobo set them to - you know because you set them yourself

LLC should be enbled - it is supposed to help keep v's level under load.
I keep qpi v no greater than 1.335 unless ocing.
You could run your mem volts higher, the intel max is 1.65 - perhaps even as high as 1.875v.
One rule that many of us have used is to keep the mem voltage no greater than .5 v higher than the qpi.
So for example - if you set your qpi to 1.335, you could set you mem voltage as high as 1.835v.
This is what has worked for me but as always - YMMV.
Other max v's below.
