How to solve DDR5 X.M.P. not running at full speed.

So you spent that extra money and went for DDR5, but it wont work at the rated speed!? Hopefully this short description on how to solve the issue that DDR5 sticks does not run stable at full speed or with X.M.P activated will help you!

For solving 4 sticks 4:00

For a more in depth video on the 4 stick solution:

Thank you all for your positive feedback and collaboration so far.

The manual says clearly that with 2 sticks you have to use A2 and B2, this is true for almost every mobo with 4 slots

After a day of trying raising voltages slightly and lowering the speed step by step all to avail I found your fix and it worked first time. Thank you so much for posting this. My blood pressure has now returned to normal.
If anyone wants to know I am using an ASUS ROG Strix Z690-E 2x with Corsair VENGEANCE DDR5 64GB (2x32GB) 5600MHz

I had the exact same problem on my ASUS Prime Z790 A MoBo however my fix was a slight variation of yours. When inserting the DIMM's into slot 2 and 4 the bios would not even boot up. I solved the issue by just inserting 1 DIMM into slot 2, go into the BIOS and turn on XMP 1. Then the stick would run at full 5600Mhz. After that worked, I put the second stick into slot 4 and everything has been working fine ever since.

Thank you for this great video. Certainly helped me and sparked my creativity and problem solving 🙂

Thanks to this video I was able to boot my memory at 5600 instead of the default 4000.
Changing the memory to the 2, 4 dimm slots solved the problem.

Yo bro u SAVE ME !!! 5 hours of booting, many of reseach ! And i find your video. Thx a lot mate. S/O from FR

Wow. Been trying for a week to get my DDR5 working and then just came across this video. Worked first time. I did the same as a lot of people, I assumed the mobo wants it in A1/B1 but the manual says otherwise after re-reading it after this video. I bought some expensive 6400 Trident Z5 which wouldn't even post above 4600. Now it just booted straight into 6400 no problems. Thought I was going to have to return the RAM.

This actually worked for my 2 sticks of 16GB DDR5 7000. I was stuck in a bios loop for hours. Updated the bios on my Asus Rog Strix Z790 E-Gaming Wifi, defaulted all bios settings, switched sticks from A1/B1 to A2/B2. Switched profile to XMP 1 in BIOS. Booted up first time. Remember to safely update your BIOS too folks, that way your hardware can be properly utilized!
Thanks again!

[smeghead]

this worked for me, im using ddr5 64gb 5600mhz 4 dims, when xmp is disabled my ram runs at 4000mhz instead of 4800mhz, when xmp is enabled i run at full speed 5600mhz, thank you for this you deserve a sub! :)

[shadowminor]

Ironic you uploaded this on nov 28th. that was the same day a bios update came out that may have helped. and there has been another one since on jan 11th. With ddr5 being so new, it is good to keep the bios up to date

got this to work for my 2 sticks of 16gb ram not enabling xmp on my asus z790-p mobo. switched ram stick to slots a2/b2, went into bios and changed to xmp 1, saved and restarted and it fired right up. thank you for the video.

Gotta give you credit man, after having intermittent stability issues trying to run my 4x16gb DDR5 overclocked, it looks like changing from "sync all PMICs" to "By per PMIC" may have actually done the trick. Just got through 8.5 hours of MemTest86+ at 6000 MT/s CL30 with 0 errors after bumping VDD and VDDQ voltage by .05v and changing the PMIC setting. I'm hesitant to declare victory, I still need to do real-world tests, but initial results look super promising. Thanks.

[IAMRUSTEDROOT]

Weird. Every modern PC I have built says to put in A2/B2 if using 2 sticks.
Pretty sure I've done Asus boards and don't remember ever putting ram in A1/B1.
I thought that perhaps changed with AM5, but the new AM5 board I just got says put in A2/B2 as well.

EDIT: And now I am more confused. What Asus board do you have? I looked up the Asus Z790 and it's manual even states to put in A2/B2.

CORSAIR VENGEANCE DDR5 RAM running in XMP at 6600MHz thanks to you!

I can't believe I have spent so much time troubleshooting this.

[Deelabit]

I've gone though a dozen videos looking for the fix, your video with the simplest solution is the one that worked

[giorgiobellia]

Hi, thanks for your support. In the boot menu I don't have VDD and VDDQ but VDD2 and VDDQ. Also, I can't find the setting PMIC Voltage but many settings for sync or split voltage settings. My motherboard is Gigabyte Z790 Gaming X AX and I use 4 sticks of Kingston Fury RGB 16gb 5600hz. Can you help me? Thanks!

[AChillBear]

I got a similar set up to you with 13900k, same mobo and 4x16gb DDR5 sticks. For the past month I've been having crashes and figured it was the ram. Ran memtest86 on single and dual sticks without issue but failed with the sticks together. Going to give this fix a try now and see if it helps!

[scottf]

Can't seem to find a video for MSI motherboards to fix similar problems. :(

I have „DDR5 48GB (2x 24GB) Corsair Vengeance RGB black DDR5-7000“ stick on a2+b2. After activating xmp profile windows bluescreen 😔

[ColinDyckes]

RAM slots are ALWAYS A2 and B2. Reason is very simply that these are at the end of the address and data traces and so the traces are terminated correctly by the memory. VDD and VDDQ may well need increasing for XMP stability.
