stock multi is 18 so...so now I just set multi to 16.5 and oc HT no throttling at all no matter what temp I reach...dangerous but fun

Im assuming you still have turbo core turned on.. ?
Are you currently using the stock cooler, your voltage & temps dont seem to match up. thats pretty good undervolting there 1.3v @ 4.4ghz but your temps @ 53c with only 1.3v is quite high. whats is your voltage on your CPU-NB (stock is 1.17v) though I do suspect your board has LLC = Load Line Calibration which can add upto 0.8v give or take a 0.2v depending on your board make/model.
what does CPU-Z say when your prime 95 testing.? That will give you a more accurate reading of your voltages. im guessing @ 4.4Ghz your probably pushing close to 1.39v-1.41v with LLC enabled. but I could be wrong...
I needed 1.4156v (BIOS) to make it stable @ 4.6ghz with LLC set to AUTO it goes upto 1.4680v adding +0.5v for stability (full load CPU-Z reading)

No I am not running a stock cooler, and i am overvolting, not undervolting.
It holds at about 1.344 and it will occasionally drop to 1.296 or 1.264 from time to time. i got about 1.26 on the NB

Yo "seth" you need to post some screen shots of CPU-z in Cpu, Memory, and SPD tab. Would not hurt to have a post of HWMonitor from CPUID and click on the down the page where the cpu is listed and it will show what is supposed to be core temps.

looks like your being throttled back to a multi x16.5 as the cpu protects itself what is your socket temp when running prime ?
Have you disabled all of the power saving features in the BIOS ?
Cool & quiet / EUP / C6 state/C1 state/ should all be off when overclocking..
you can always turn them back on when you find a stable OC.
with them on your clock speed & voltage will fluctuate up and down. In order to get a more accurate solid reading those power saving states above need to be turned off. then post a pic of you running prime with socket temp and core temp showing and voltage in Hardware Monitor
good luck

No water blocks for me... But, yeah I have those all turned off. That was the first thing I did. Here is another pic.

Ok, i reversed the direction of my case intake and exhaust fans, as well as the direction on the heatsink fans that way it takes air in from the front and spits it out the back. Where as before I had it take air in from the back and spit it out the front..
However, when i did that i found that one of the fans on my heat sink had died /: so i gotta get a new fan for it...
On the bright side, even without that fan the temperatures are now maxing out to 43C so about a 12 degree drop!

Ok, this is a little bit late of an update but I figured I might as well keep yall in the loop since you all have helped me so much.
I updated to the BETA bios and it allowed me to turn of APM, that has eliminated my throttling issues. Also, by putting an sythe ultra kaze on one end of my CPU heatsink has allowed me to run at 1.38 volts at about 55 C. My current clock speed is 4.44 ghz 21.5 mult and a very slight FSB OC. When I set the mult to 22 it fails on prime and I dont feel like i can really squeeze in more voltage out of her.
So now begins the task of working on the RAM and possibly the NB.
Any advice?

Working on the ram to do what? You would have to up the ram voltage to at least 1.6 volts to try to tighten the ram timings from 999 you have to 888 and then the ram needs to go to 2T instead of 1T and so on. Not much use it really seems.
The FX processor with IMC has not shown to like high voltages on the ram. I have seen many recommendations to make sure the LOW voltage ram is used lately.
So in general you can play with any of your parts and pieces. You will have to do some serious benching though to notice any real difference from this point on though in all likelihood. Bench away though since it can be fun if nothing of value is on the hard drives.

That depends mostly on your airflow. Cool silicon can run faster. When I added a fan that blows across the mobo (mostly socket and VRMs) I positioned it so that the RAMs get some airflow too and I can push them quite a bit further now.

They should do there rating at the 1.5v so you can turn it down. If you find it starts behaving badly turn it back up. Or leave it up and see if you can get some free MHZ out of it. I bet that those 1333s will do 1600 on those same timings with 1.6v on the FX IMC.

My RAMs are 1333 ECC DIMMs from Kingston and they run 1866 at 1.45V. Maybe I can do more. They have pretty recent low voltage Elpida chips (1.35V nominal) that are available in 1866 bins. The good thing with ECC RAM is you can watch for errors. When they run too hot or too fast I see an ECC error every few minutes.
