Question Can not use A-XMP on my B450M Gaming Pplus

[bond47]

this spec of my RAM i cant use A-XMP on BIOS i dont know why but i can use memory try it preset. my CPU is R5 2600 and mobo: MSI b450M Gaming Plus. is my RAM the problem why i cant use A-XMP

Sometimes when i overclock until 3400 with fast timing my pc get bsod even i turn up the ram volt till 1.4v

What are the timings? Find proper timings, DRAM Voltage, SoC Voltage to support the OC. This is the difference between using a DDR4-3400 rated kit. Since results are unknown, trial and error testing is necessary to determine what can work.

Now i found the stable oc for my ram, i turn it up to 3333 18-18-18-36 1T 1,36volt

2666 RAM does not have a xmp profile because it falls under a jedec standard speed. If you load cpu-z then go to SPD you will see JEDEC #7--#8 etc. Your RAM profile should be there. Also on the right hand size there should be listed any xmp profiles etc. cpu-z link

If you are going to overclock your RAM, I would advise using Ryzen DRAM calculator.

memtest86 and Ryzen dram calculator can be useful for testing. Ryzen DRAM calculator link

B450M-GAMING-PLUS Specification link

I appears that this motherboard supports memory speeds up to 3466 MHz.

2 x DDR4 memory slots, support up to 32GB

• Supports 1866/ 2133/ 2400/ 2667Mhz (by JEDEC)
• Supports 2667/ 2800/ 2933/ 3000/ 3066/ 3200/ 3466 MHz (by A-XMP OC MODE)

a-xmp is at 5:41 it looks like you pick your xmp profiles there as well.

So memory overclocking could hit a wall after 3200. 3333 18-18-18-36 1T 1,36volt looks like you have got started. Be careful with the voltage. Note Jedec standard ends at 1.4 volts. JEDEC DDR4 wiki link

Thanks mate, very helpful i'll try it
