I want to see if the vdroop on your ram or the slight lack of voltage on your cpu/nb might be the culprit

Nope..Cssorkin was asking about my batch number too but I don't have it unfortunately. I lapped this chip some time last year and I lost the photo I had taken of it while reformatting. Purchase date for this chip is Feb 19th 2013 so I think it's a fairly early batch since the chip was released Oct 23rd 2012 from what I can see.

I'll give those suggestions a try now before I change the Digi+ settings. Wish me luck!

yup, you got an early piggy..

lets hope yours doesn't fall into the same catagory as mine... stellar IMC, weak as snot cores above 4.7

How long can you run Prime small FFT? Or Blend?

I'm gonna try upping the DRAM and CPU-NB voltage real quick as per Flail's recommendation and when I do I'll try running p95 after a quick 10 pass of IBT.

Alright so I bumped my voltage and passed with 4.5ghz. But it keeps jumping between 1.392 and 1.404 while the IBT test is running. Is this normal?

Yes. Voltage fluctuates.

Take a look at the OCCT charts here: http://www.modders-inc.com/gigabyte-990fxa-ud3-rev-4-0-motherboard-review/4/

They illustrate how higher LLC is not always optimal, too.

with some Vboost yes.

keeping voltage consistently static over idle and load periods is just not possible

its easier to lock up a chip with over vboost than it is for slight undervoltage

for example my 8370e clocked @5ghz has a voltage of 1.52-1.53 while idling, yet under load it only draws 1.468v

there is a very important balance going on behind the scenes.. https://en.wikipedia.org/wiki/Ohm%27s_law

to maintain a certain wattage, the amperage and voltage can fluctuate in accordance with each other to come to the required wattage load.

in the case of volts @ idle being higher, this simple means that the amp draw during this time is going to be significantly lower. in the grand picture you are saving power at idle but it really isn't much.. 0.02kw/h at best maybe? what this power savings actually does is put less thermal stress on the components.

Amps will heat your stuff up faster than volts.

to put it in context, typical north american house voltage will not kill you(nor will EU house voltage) but the amperage available in the house will kill you. (yes there is a point that volts will kill to but you don't see that outside of commercial/industrial) and its very specific this is how people survive lightning strikes. the voltage is insane, but the amperage is so low that if the path of the electricity doesn't cross your brain or your heart , there is a likely hood you will manage to make it to your next Xmas if you don't have an Aneurysm while recoving from the shock (not the electricity the mental state) of what had happened.

(edit: for better math, after beer i cannot be held responsible for math)

Well it looks like I'll have to settle with 4.5ghz at 1.4v
I've tried 4.6ghz with 1.4v, 1.4125v, 1.41875v, 1.425v, and 1.431v and am unstable in IBT and socket temp shoots to 68 quickly

Alright I ran p95 Small FFT for 30 mins and Blend for an hour, neither had errors or stopped but I figured I'd stop there and post back the results. I ran IBT once before p95 and once after..curiously the run afterwards almost completed and I didn't change any settings between runs.

care to post some Bios screen shots in a spoiler?
