I am running it on a GA-990FXA-UD3 mobo, rev 1.1 with F9 BIOS.
The cooler is Noctua NH-D14.
RAM is Corsair Vengeance blue 2x4GB DDR3-1600 . Waiting for my 4x8GB DDR3-1866 for Newegg. Hope they will fit with the Noctua ..
I'm using a Cooler Master HAF-XM case with a 200mm side fan installed.
PSU is Raidmax 1200W.
This build also has the best cable management of any PC I have ever built, considering it has two SSD in RAID, two HD also in RAID, and two GPUs (560 Ti and 9800 GT0. Plus another Sil3132 card for the eSATA enclosures... Really loving the new HAF-XM case.
Now on to the overclocking part.
I can OC to 5GHz at 200x25 and increasing just the vcore. Windows boots OK. I can do about a couple minutes of video encoding with no issue.
But Prime 95 is another story.
I disabled all the power saving stuff (APM, C1E, C6, etc) to try to stress it. Put Windows in high perf power saving mode also.
And running P95. At 5 GHz it almost instantly hangs the machine completely. No one has done 5 GHz on air with this chip and I probably won't be the first, so I am not really trying to reach for that high for now.
At 4.6 GHz, I was able to run about 7 hours, then one thread failed. This is probably longer than I will ever stress my CPU so it is probably stable enough at 4.6 Ghz.
I have been trying At 4.8 GHz which has been done on air by at least a couple people with the NH-D14 . But having a hard time getting P95 to run for more than about 30 minutes no matter what BIOS settings I try.
I would appreciate hearing from other 990FXA-UD3 owners with this chip what exact BIOS settings you are using .
My last attempt was this :
CPU clock ratio x24 4800
Northbridge freq auto 2200
CPB off
CPU host control auto
CPU frequency 200
PCIE clock auto

HT link width auto
HT link frequency auto 2600
DRAM EOCP Disabled
set memory clock Manual
memory clock x8 1600

voltage Manual
CPU PLL normal 2.5V
DRAM voltage normal 1.5V
DDR VTT normal 0.75V
NB voltage normal 1.10V
HT Link voltage control normal 1.2V
NB/PCIe/PLL Voltage Control normal 1.8V
CPU NB VID normal
CPU voltage +0.15V 1.4875V

Load Line Calibration Extreme

Prime95 fails at 30 mins
I have tried lower Vcore voltage but usually P95 fails even earlier at 4.8 GHz ....
Maybe OC with the FSB is the answer with my chip ?
But I have not been able to increase the FSB even to 225 without getting the mobo completely unstable, to the point of not even getting to the setup menu and having to clear the CMOS pins ...
It's a PITA having to reset all the other 20+ BIOS no-default settings that are not related to OC, let alone the OC settings.
If you are using this board with FSB overclock, I would like to know the secret. And yes I know to set PCIE to 100 and lower the HT frequency and memory clocks. Even with the very lowest multipliers that the board will allow (underclocking to 1.5 GHz or so), I could not get FSB of 225 MHz to properly boot...

Although I'm still testing out overclocks with my own new FX-8350, I would already suggest that you might want to use the 'High' LLC setting, as opposed to 'Very High' or 'Extreme'. The reason is that the 'High' setting, at least on Gigabyte boards, will stabilize the voltage at your requested level, but no higher than that, and this is probably the best setting for a cooling-limited situation, especially air-cooling. You air cooler is already being strained to its very limits with the 4.6GHz overclock, so that core failure is probably happening due to a very slight increase in heat build-up that's pushing the core just past its thread failure temp (perhaps the ambient room temp went up a degree or so, who knows). I think the 'Very High' and 'Extreme' settings might work better for those using good water cooling, and who have a little bit of extra cooling margin available if the voltage ramps up slightly under load.

Just my thoughts.

Lol stable enough... if you aren't stable at 4.6 what makes you think you will be stable at 4.8? I don't mean to be snide but stability is either a yes or no, no kinda's.

FX-8320
Asus M5A99X EVO R1.xx (BIOS Version 1604)
Cooling: Corsair H100i (but fans plugged into motherboard and running at 60% due to Corsair Link's incompatibility with Windows 8, separate fan controller arriving soon)
Settings:
vCore: 1.45v
Multiplier: x24
Memory: 1600 MHz, 8-8-8-24 1T
CPU-NB: 2400 MHz
HT Link: 2200 MHz
Power-related settings, except for C&Q: disabled
CPU LLC: Ultra High
CPU Current Capability: 140%
CPU Power Phase Control: Extreme
CPU VDDA: 2.7v
DRAM Voltage: 1.5v

must try your set up. i also have 8320 but i only over clocked to 4100 with H100

another things is it doesn't downclock when im at idle,

I have that motherboard in my wives machine, and I do not see an option to change throttling temps in the bios immediately. You may have to find something else, I'm not sure.

the situation is like this,
i set the multiplier to x21 and vcore to 1.3875
after several mins on prime 95
the multiplier automatically goes down to x7
i turned off already the
c n q
cpu throttle
apn
and turbo core
do you know how to solve it?
thanks!
mobo is asrock 970 extreme 3 bios 1.7

I have the same prob on a giga fxa-ud3. Temps are low cpu 47 nb 68

68 is getting toasty. It might be starting to throttle for protection

I thought NB temps could get into the 70's with no prob?

Every one has their own preference, but If I were to do only 10 runs IBT I would do them very high and if it passes you can quit or give it an additional longer run of 20 times at standard.
