new build randomly bsods and freezes, memtest and prime 95 error

hey guys, i recently built a new system, and its been freezing and getting bsods randomly doing basic tasks such as web browsing.

specs:
fx6300
asrock 970 pro 3 r2
kingston hyper x blue 8gb kit (khx1600c9d3b1k2/8gx)
gigabyte r9 270
sandisk ultra plus 256gb ssd (os), 2x 500gb hdd, 1x 320gb hdd,
Antec Neo Eco 620C

the system has not been overclocked in any ways.
initially, i thought it might be windows update causing problems, so i reinstalled windows, but problem persisted.
i ran prime 95 in place large fft thinking that it could be a temperature issue, but the cpu never exceeded 60C on the stock cooler. (currently cooled by a thermolab baram at 40C load)
i then ran memtest which identified 2 errors during pass 3. this was when i realized that the ram wasn't running at kingstons advertised timings of 9-9-9-27, instead, it was running at 11-11-11-28. i manually adjusted the timing to 9-9-9-27-2t, and reran memtest. this time, i managed to pass 7 passes, at which point i exited memtest and booted into windows, only to find out that the system was having more frequent bsods and freezes.
i ran prime 95 again, this time with blend test, which immediately resulted in errors. i reverted the uefi back to default settings (ram back to 11-11-11-28) and reran prime 95 blend, which again resulted in errors.
currently, im running only one stick of ram in the first slot at 11-11-11-28 1600mhz. it managed to run prime 95 blend without errors for a while until i closed it to rerun memtest, which is currently running.
do you guys think that its my memory causing instability, or could it be cpu or mobo? is it normal for the system to pass 7 passes of memtest but fail p95 blend test immediately? could the looser timing be an issue? and any idea why the motherboard isn't running the ram at the advertised timings?

any help will be greatly appreciated.

  1. check that your motherboard running the newest bios file so it has the newest ram code. make sure your running the newest amd chipset driver from amd. in the asrock bios see if it has xmp profile like intel mb do. if not set the ram to 1333 and see if it stable.

    thanks for the reply, forgot to mention, first thing i did was update uefi to the latest, which didnt seem to improve the situation. all drivers were the latest downloaded from the website. I've also tried xmp after manually setting the timings, but that also failed prime 95. Haven't tried setting ram to 1333 though, will try that tonight if memtest fails with one stick.

    also if i leave timings as the mobo configured as default, which is 11-11-11-28, could the looser timing cause instability?
  3. Try them at stock timings and raise the DRAM voltage + 0.05 and raise the CPU/NB voltage to 1.18
  4. my single stick of ram just did 15 passes of memtest with no error. gonna use computer normally and see if i get any bsods or freezes, gonna run memtest with my other stick of ram tonight to see if its faulty.

    stock timing as in the one from xms profile and not what the mobo is assigning by default right? ill try raising the voltage if my second stick fails memtest
  5. Keep us posted
  6. hmm.. system crashed randomly a few times and once after sleep mode with the one stick that passed memtest. im quite confused now, maybe its not a memory issue after all? :S
  7. Do you have latest BIOS and Drivers for Mobo and GPU?

    yes. the uefi is updated to the latest version and drivers were downloaded straight from asrock and amd website

    Try the CPU/NB voltage to 1.23
  10. hey guys, sorry for not posting back for the past week, ive been busy so havent really had time to play around with the computer.

    I tried that and ran prime95 blend test with it. had a few workers fail within a few minutes.
    also tried that with ram running at 1333 both with xmp profile and auto settings, both failed within a few minutes. any advices?

    edit: after playing around in the uefi a little, i realised that i had increased the voltage on the nb and not the cpu/nb. after upping it to 1.23, problem seems to be solved. thanks.
