Oops!
 

Well appears I perhaps made a boo boo last night.

Purchased some RAM for a decent price (used) made sure it worked and it did.

Then put it in my Gigabyte GA-890GPA-UD3H & 1055t (was at 3.7) now just stock lol :(


Anyway the RAM I had in it originally was :
Mushkin Blackline 996652B : 7-7-7-20 1.7v (is what the sticker on ram says)
RAM I put in with it :
Mushkin Blackline 996782 : 7-9-7-24 1.65v (is what the sticker on ram says)


This machine was overclocked which I think was my issue :(

Perhaps I should have never mixed these in the first place.

Anyway hopefully my RMA will be accepted :(


Appears only one stick of the 996652B died (as I memtested all sticks except the one)
as it won't even with that one stick let me get past the MOTHERBOARD POST SCREEN
I see the mobo logo but can't get to bios or anything just freezes completely :(




Any thought's suggestions etc are appreciated thanks!

Well if you can boot up with any of the rest then you've indeed found your problem, but mixing RAM isn't a bad thing, you can mix and match all you want. Overclocking shouldn't have broken anything unless you severely overvolted the RAM.
