I have bought Asrock J3455-ITX combo motherboard, which says DDR3L 1866 So-DIMM, I am using Crucial 2-8GB DDR3L-1866 SODIMM 1.35 CL13. The machine does not boot. I tried with old 2-4GB (DDR3-1333) working perfectly alright. What is it wrong.. why the specification mentioned in the motherboard does not work ?

Any suggestion .

Thanks for the extra details!

Crucial memory part number CT2K102464BF186D is compatible (ie memory has been manufacturer tested and verified as working with the motherboard). So incompatibility is not the issue here.

First. Make sure the 2 x 8 GB modules are seated properly. Then clear CMOS and try to boot again.

If still have problems booting, try to boot with ONE of the two 8 GB modules.

If system boots and runs with ONE 8 GB module installed, then shutdown and add the second 8 GB module and try booting again.

If system doesn't boot with ONE 8 GB module installed, then try the second 8 GB module in its place (ie swap modules and still trying to boot with just ONE 8 GB module).

If system doesn't boot with either of the 8 GB...

The 2x8 GB Crucial memory modules are from a kit. I bought 16GB (2x8) kit. Crucial 16GB Kit (8GBx2) DDR3/DDR3L 1866 MT/s (PC3-14900) SODIMM 204-Pin Memory - CT2K102464BF186D

If system doesn't boot with either of the 8 GB modules installed, then possibly the 8 GB modules might be faulty.

In this case, boot into BIOS (using old memory as required) and set DRAM Voltage manually to 1.40 V and try the 8 GB modules again (one at a time, then both).

If system still doesn't boot with either or both 8 GB modules installed AND DRAM Voltage has been set to 1.40 V, then boot into BIOS (using old memory as required) and raise DRAM Voltage to 1.45 V. Try to boot with the 8 GB modules again (one at a time and then both).

Thanks for the feedback, I tried with only one 8 GB card and switching the modules and alternately clearing CMOS, it works .. but unfortunately does not work as soon as i put the other module.

- Booting with one 8GB module works
- As soon as I add the other module it does not work
- peculiar only works with the memory slot B1 not A1
- but with 2 x 4GB both slots works ..
- Alternating the memory modules and putting into one memory slot works .. ( so the memory are not faulty)
- may be something to do with the power supply (picuPSU) ?

Thank a lot for the suggestions .
