I have a very odd situation, nothing i've found has been similar... When booting there are two scenarios.
1. Boots normal, goes through post fine and windows loads
I shut computer down and then when I turn the computer back on it wont start and stops on post code 2f (Memory Initialization (other))
So half the time my computer works, the other half it does not. I'm also able to get around the computer posting 2f by either unplugging the psu or clearing cmos. I have not Overclocked my system or anything and I'm quite lost as to what is going on.

Core i7 2600k
Asrock z68 extreme3 Gen3
ABS 1100 W psu
EVGA gtx580
Thorv2
Edit: Suppose the type of ram is important? Hah.
Gskill Sniper Low Voltage 2x 4gb ddr3 (Says it's compatible on mobo website)

Huh, strange. That shouldn't cause errors on the board to show though, probably just cause strange resets and hang ups. It's not essential to be plugged in though. Just means you can't use the reset button :)

sure enough, pass 3 test 6 brought failure... could it be that both sticks are bad given I've tried to trouble shoot 1 stick at a time, or more likely the board? guess I'll just RMA both today.

If you bought both sticks together as a kit they'll want both even if one is good. I'd probably rma the RAM and if you don't think you'll run out of time to rma wait for the new sticks to come so you can test and see if all your problems are gone before rma'ing the board (you could do the board too since it seemed to have a weird network quirk)

Have you tested the new sticks?
If they pass for 6-12 hours then you at least have one problem solved. It will come down to possibly the psu (for the computer not starting) or the board again (for the error code it shows). I had 2 bad ASRock boards in a row when building for a friend. It's rare but these things happen.

ran mem test for 10 hours and no problems (10 passes) I have replaced the psu as well and i'm still getting the same results... I've even tried different outlets and different surge protectors..

So its still showing the f2 error?
I recently got the same board as you, I haven't had any issues, but I wouldn't rule it out that the RAM isn't compatible, it says so on the site but its making me skeptical. Have you talked to asrock? Now that I have the same board maybe I can help you out in BIOS a bit better. Manually type in your RAM specs printed on the sticker that's on the heatsink of it. If that doesn't work try auto instead of xmp.

I've read of other people having the same ram with the board so I know it is compatible. though in bios for whatever reason it is 9-9-9-28 rather than the listed speed of 9-9-9-24

Call asrock, they should have the same parts on hand since they say its compatible, they should be able to help more on this, they have glitchy BIOS so they should be familiar with the problem you are having. Just be sure to mention the error code and that your RAM passed memtest multiple times. They should be able to say if its bad BIOS or another bad board

I've been running through their suggested steps (same as yours) and nothing is working haha. how could it be that i get two of the same board with the exact same issue? seems super off to me.

Oh and i remembered , the other problem why i had BSOD and had memory errors it was the CPU load line calibration it was set on the lower level and i set mine to level 3 and the BSOD's have gone. I found this explanation after i googled an entire week. I hope i could help you.

Strange that switching to corsair fixed your problems, I had the opposite, I switched to g.skill because I kept getting either bad RAM or problems with corsair unfortunately.

And getting two bad boards happens... I build pcs for friends and family and one time had two boards back to back with problems, eventually I just went to a local pc shop and dropped my stuff in one of their boards, once working I paid and left with a working one.

turned out to be a bad reset switch header.. once It was pulled it starts up every time no problem, my question now is... What exactly does that do while it is plugged in and is it necessary? Basically, from my front panel to the mobo the wire is bad and was screwing up my boot, I don't understand what it does and can't seem to find any info on that.

Can't believe that was it, caused the rma of a lot of good parts! :/ now I feel bad haha! Thanks for all your help. Pretty awesome that you can find helpful people on the internet!

Yeah, I returned a few things that probably didn't need an rma before, but it can't be helped. Trial and error :)
Glad we could help you out even if you figured it out yourself :lol:
