Motherboard wont see 4th Stick of Ram

[beauman7]

When putting the 4th stick of Ram in the computer will not boot.I can get it to recognize 24GBs in the first three slots. I disabled quick boot. Updated bios to 2601 I believe. Also the ram is not running at 2133 it sees 1600 I understand its O.C but has anyone in the community achieved this with my setup?

Motherboard: ASUS M5A97 LE R2
CPU: AMD FX8350 4.0ghz(
RAM: DDR3 2133 (OC) GSKILLS 8GB ( x 4) ( I have two 8GB Ripsaws and two 8GB Ares)

Try to clear cmos, its mostly solves all bios related problem.
How to do it? Refer to your mobo's manual or just simply pull the CMOS battery and leave it for 5mins then reinsert.

AMD FX CPUs support 1600MHz with two DIMMs per channel. ASUS M5A97 LE R2 is a dual channel motherboard.

Mixing up different memory sticks often leads to an unbootable system.

You must be quite an overclocker to achieve 2133MHz speeds with all memory slots filled. The ASUS M5A97 LE R2 is a economy model motherboard not well suited for overclocking. 1866MHz speed is supported with one DIMM per channel with FX CPUs with no overclock.
