A quick update:

I ordered a new kit of the same memory and tested each module separately. I plugged in one module at a time and everything works flawlessly, there are no errors! This proves that in the old memory kit, 3 out of 4 sticks were faulty.

The new kit serial numbers do not run in order - as it was with my previous kit, this is apparently not followed by HyperX, however, they do work.

As to the old kit, I was just issued a full refund and postal fees.

Many, many thanks to everyone on this forum!

Your prompt advices helped me pinpoint the issue in memory modules.

Thanks!

Keep us posted after the exchange please.

Will do, I have just requested a replacement of the same RAM kit. I will update the topic in approximately two weeks.

Thanks for the help.

- yes and no, their serial numbers end with these numbers:

T000052 - raises C0 when used in single channel in any slot (A1 to D2)
T000053 - same as above
T000062 - same as above
T000063 - works in any slot, doesn't raise any BIOS errors

Thanks!



Not good. If you bought this as a 32GB Kit with 4 sticks, return it.

While "close' , you nor I can guarantee this is 4 Matched sticks.

Kit serials run consecutive.

Fishy and dodgy.

I didn't know that, I always thought that they work only when all 4 are plugged in. Thanks for the insight!

@gr1zzly Don't be confused by the fact that CPU-Z shows the actual clock frequency for your RAM. 1200 MHz is correct for DDR4-2400.

You're right, I didn't know that!
