Windows 7: AsRock h55m-LE won't boot up with 2x4G DDR sticks

AsRock h55m-LE won't boot up with 2x4G DDR sticks


I just got a brand new mobo, AsRock h55M-LE. I got KHX1600C9D3K2/8GX (2x4GB) 1600MHz DDR3 CL9 XMP memory sticks. When I try to boot up with one stick which is in slot DDR-B, the comp works. If I put another stick in DDR-A, comp boots up for 5-7 seconds and reboots. I use only one stick in DDR-A it's gonna be same error. So atm only DDR-B with one stick works.

I tried to change timings and voltage in BIOS and result was this:

9-9-9-27, dram volt 1,65, vtt auto and both sticks in boots up for 5-7 secs and reboots (there's no pic in monitor etc)
9-9-9-27, dram volt 1,65, vtt auto and one stick in everything works.
9-9-9-25, dram volt 1.5, vtt auto and two sticks in comp boots and stays on but there is no pic in monitor or any light on keyboard etc..
9-9-9-25, dram volt 1.5, vtt auto and one stick in everything works.

And also tried to change dram frequence but it's the same with all.

I have tried both sticks and they both work.

Is there something else I can try to change? Or could it be it's just the mobo that's broken? Tho I found that ppl had similar problems with this mobo, but there wasn't any solution.

Windows 10 64 bit

I had a memory problem with a new ASRock Z77 Professional motherboard. As it turned out two out of the four memory slots were bad. After exchanging e-mails with ASRock support, the motherboard was replaced and now works OK.

I had used GSkill Ripsaw memory that was listed by ASRock as compatible with my motherboard.

ASRock A75 Pro4-M or Asrock B75 Pro3-M?
I used the A75 Pro4-M in my current build, but I'm building another for a friend. I'm not sure if I should go with the same board, or use the B75 Pro3-M this time. It's hard to find any reviews on either of these boards. I like the PCIE spacing on the A75 board, but I'd also like to try the...

RAM... Two sticks, three sticks, dual channel, triple channels, huh?
I ordered some computer stuff at 4a.m. and I had a major brainfart when doing so. I ordered some Crucial ram that came in 2GB sticks, sold is in doubles and triple packs, my thought was well, 6GB is better then 4GB when ordering but after doing so I thought, wait, don't you normally...
