This is not my sig rig! I just put together a AMD rig for a back-up and i do have some experience with OCing but, this BIOSTAR 790gx 128m with a kuma 7750 is giving me a little trouble getting past 3.1 some of these settings with the AMI bios is throwing me off. This is where i'm at now...
VC 1.344
CORE 3078
MULT 13.5
BUS 228
HT 2052
DRAM 456X2=912
IDEL 24c
OCCT 34c
MEM V 2.0
TIM 5.5.5.18 2T pc2 6400 not 1066,set as auto
CHIPSET 1.2
HT V 1.2
OK, question is do i need to disable the cpu fid/vid as it sets it at defalt when enabled, is that whats causing me to not get higher? Also under the chipset ht config do i disable, auto, pcie, or pcie/gfx? Any ideas and suggestions i can try as i think i should be able to reach 3.3, 3.4?

You might want a bit more voltage to your memory. Try 2.1v.

i'm assuming it's being cooled well.

set vcpu/vcore to 1.45
set vram to 2.1
aim 1800 ht freq
i'm not sure about the northbridge/chipset volts, but try adding it up a little bit.
set ram timings manually

Voltage for vcore is 1.392, ram at 2.0, ht 1800 and under, well cooled max i have seen OCCT & ORTHOS 34c The ram is the double sided crucial ballistix tracer stock is5.5.5.15 @ 2.2 i have lowered the ram to 667 and v to 2.0 The chipset is at 1.2 and if i up it to 1.3 i blue screen. The HT v i have not messed with. Right now i passed occt with this setting
core 1.392
mult 13.5
bus 230
dram 383x2=766
speed 230x13.5= 3.105
As i try to break this mark i can boot to windows but crashes at stress test

Edit: sorry, its 4 4 4 12 2.2

just bump the voltage and you should be able to go higher.

I have bumped to 1.392 vcore, I don't think i should need 1.4 / 1.45 to get 3.159 that seems excessive! There has to be something ive overlooked, or maybe this board is just not responding with this ram as soon as i take it off auto it BS.

no it's not. amd chips are like tanks and phenoms can go 1.5 with good cooling. excessive is something 1.6ish or for as long as it doesn't have any good cooling.

Well, i'm at work right now but when i get home i'll bump it up a notch or two on the vcore to see if i can keep stable at 3.159. I was hoping to hit between 3.2 / 3.3!!

Ok, got home and bumped up the vcore to 1.44 and run occt med data and crashed inside 2 min. I also tried orthos small fft and also crashed inside 2 min. I think i'm gonna order some new ram from the egg what do ya think of using the g skill pi 2x2 8800's instead of the 1066? I still think theres a setting thats not set or is set wrong

Well i think my instability at anything over 3.105 is my memory settings that is holding me back so what in need is someone who has this setup that can give me settings for my memory and in fact every setting they got to get me past 3.2 or higher. I am at the point right now if i can't get this higher i'm gonna pull this board and chip and sell it but sadly i don't have the reps to sell here....probably ebay???
Anyway could some PLEASE help me get this [email protected]&h above 3.2 reps for anyone who help me!
