2 days ago I bought Corsair Vengeance RGB Pro RAM DDR4 3200 MHz (2x8GB, product number CMW16GX4M2C3200C16) from the Corsair store on Amazon UK
Once it arrived I put it in my computer along with my current RAM (2 individual sticks of 8GB RAM and product number CM4X8GD3200C16W4). When it is in the computer, it will refuse to POST and some of the fans will refuse to spin unless the CMOS is reset. In addition to this, the RAM and the power indicator won't light up as if the system is not entirel;y getting the full power draw. I have tried:
- Putting the known good RAM into every slot (1,2,3 and 4) which works fine
-Putting the new RAM into slots (slots 2 and 4 in this case) and it refused to work
-Putting the new RAM into the remaining slots (slots 1 and 3 in this case) and it refused to work
-Testing each stick induvidually in different slots (the original 2 worked but the 2 new ones didn't)
-Mixing old RAM and new RAM in varying slots (computer refused to POST)
-Testing JUST the new RAM (no POST)
-Sending the RAM back and getting a replacement twin pack from Corsair Amazon UK (the new one still didn't work)
I'm assuming at this point that the twin 8 GB pack despite being Corsair DDR4 3200 MHz Vengeance Pro RGB RAM is not compatible with my motherboard, that said, is there a different SKU I could try?
I'm struggling to understand why essentially the same RAM refuses to work
What is the difference between (original) CM4X8GD3200C16W4
and new CMW16GX4M2C3200C16
