[SOLVED] BIOS woes after upgrading RAM to 4 sticks

[RCS799]

Hi,

After buying another 2 x 4GB Corsair Vengeance DDR4 2666Mhz kit to supplement the two I already had to go to 16GB, I am unable to get BIOS to run the XMP to take it up to the afore-mentioned speed. All I am doing is putting the speed up to 2666Mhz and the voltage to 1.35. The system handled this fine on 2 sticks.

I have updated BIOS and reset the defaults and still no joy. After leaving BIOS the system will reset itself a couple times then boot up with the base speed of 2133Mhz.

Any ideas?

I enclose below some CPU-Z screens:

(Incidentally, if anyone can tell me where I'm going wrong putting photos on these posts I'd be grateful :/ )

You are mixing kits, no guarantee they will work together. You can try increasing the voltage further, don't go over 1.450v and try not to go that high.
