disable CnQ & C1E (can turn back on when you are happy with you overclocking as it should still work).
keep HT-Link close to stock 2000MHz
raising NB speed and upping NB Voltage Control (lowered CPU core voltage as the IMC has more stable).
underclocked my ram (loose timing) - I save memory for last because with locked multiplier we can't just pick
what speed it runs at. using dividers and tight timing are our only tools.
Looks like you are doing a good job and taking your time.
Seems like you need more vcore.
I hope that was a typo about the NB voltage. 1.625 volt is a lot.
Biostar TA890FXE vcore fluctuated could be due to the 5+1 VRM setup.
It would not hold me back from overclocking. Just something to keep an eye on.
On Liquid Nitrogen they got a 955 to 6,477MHz accoding to HWBot
TA890FXE seems capable of 265-270 MHz HT ref clock.
Phenom II X6 1090T BE @ 3,944MHz (ref/imc/qpi: 232/2,088/2,319MHz) @ 1.452v

I believe I meant 1.1625.
my mainboard temps haven't gone much over 60C so I don't think I'm running too much voltage through it
The board actually is a 4+2 phase but has been used extensively for overclocking as far as I've seen, with no reported explosions.
My guess is the VRM's are of good quality to handle as much as a 8+1/8+2 board without failure.
Thank you guys for all of the help and posts, I'll only check in here again to post my final stable overclock or if I run into a lot of issues. After this I can overclock my CPU-NB and memory, then focus on my 7970 and max out Crysis 3.
My goal is to get this overclock to keep me going until I hopefully do a platform upgrade new years next year to either Steamroller or Haswell.Edited by Talon95 - 2/19/13 at 2:20pm
