Hi all and thanks for any replies I get ahead of time,
2 days ago I built my second PC and everything went together great, but I did something stupid, I flashed my bios with the most up to date one from AsRock's website which was the same version that was on my mobo (which I failed to check prior) and then I started getting all sorts of bsods. After trying re-installs and this and that along with a little research, I decided to go with the memory management fixes. I have not run any memory test other than what comes with windows, but what I did was pull 2 sticks of my 16gb ram and do a fresh install all over again and voila! things have run perfectly with no errors. Now prior to my bios flash I had no issues, so Im assuming my mobo dimm slots are fine, I could be wrong, today I plan on rotating the 2 sticks pulled into the dual slot with my other to find out which one is bad if it is assuming I'll just bsod on startup again. Now I have read that its better to run only 2 out of 4 slots of ram and I was wondering why that is, because if I identify the ram stick to have gone bad, I may just switch to 2 sticks of 8gb vs the 4 4gb.
Question being....can i test the mobo dimm slots with software or do I need to install known working ram into the slots to find out if the slots are bad. And if I may, a recommendation on 4x4GB vs 2x8GB of ram for which setup would be optimal with that whole filled ram vs half filled ram on the mobo argument
System Specs: Providing what should be valid to the problem
Win 7 Pro 64 with SP1
Asrock Extreme3 Gen3
corsair vengeance 16gb 4x4 ram
Ok so I put in all 4 ram modules and ran memtest86.......had over 7 million errors at around 69% of the first pass.......so obviously my ram is jacked up......instead of waiting for a full pass I ended it early with a power down (probably not a good idea) but knowing ram was bad I wanted to check the dimm slots now.......so I rotated sticks out of the 2nd dual channel slot and each time with a different combo I booted into windows np.....so I tried all 4 again and went into bsod as before.......at this point im guessing its both the ram (since memtest had so many errors) and the mobo (since one dual channel works but both at the same time dont) would anyone recommend I just RMA them both after that?
Im currently running the tests, letting it run 7 passes before I call it good....and at this time I have 2 of 4 passing with no errors with the use of slot A1. With my ignorance of how memtest86 works I thought it would tell me errors on the module plus the dimm slot but I read a nice little guide and from that Im gonna go with if all 4 pass error free after 7 passes in a single dimm slot......than the ram is good to go, and its the mobo that will need replacing. Should I even bother checking other slots?
According to the bios and the specs of the ram...they are setup in the correct timing and voltage....the only thing would be the bios auto sets it at 1333 and then I changed it to 1600 and first go round no problems it was after the bios flash to the same one that was already on the board that the problems started....I did a clr cmos and still had the problems so Im currently doing the memory tests.
After memtest86 I had 1 of 4 sticks with over 21million errors, running all sticks in slot A1, afterwards I took 1 good stick and checked my 3 other dimm slots B1,A2,B2 and all had passing tests. I'm wondering why I was able to run all ram combinations in slots A1 and B1 for dual channel and it boot fine, even including the bad stick. It was just when I used both dual channels that it would error. In any case I'm going to RMA the ram. Thanks for the help
