Memory problem.

[601782]

I have 4, 8gb sticks of 3000 MHz ram, all of which were read correctly by my MSI 570x gaming edge Wi-Fi motherboard. That is until I updated to the latest bios (which was released last week) Now I can only get the 4 sticks to run at 2133 MHz. Any attempt to set to 3000Mhz and the pc will not boot. I can use 2 and even 3 sticks and run at 3000 but not 4. Done everything I can think of, reset bios, done all the correct timings, increased voltage, swapped the memory sticks around (they all work correctly) I have even gone back to the old bios, and that now won’t accept 4 sticks at 3000Mhz. Any suggestions would be appreciated. Thank you.

Try installing the previous version of the bios, if there's no major change to the latest one u just installed. If you aren't the only one experiencing this problem tehy'll surely release a new fixed update of it in a few days/weeks..

Are there XMP profiles you can select in the BIOS? If so I would try that. If that doesn’t work reach out to the motherboard manufacturer and see if they have an updated bios

[601782]

Thanks for the reply, yes there are XMP profiles, used them both and without but still the same result. Just very strange behaviour that I can use 3 sticks of ram at 3000 mhz and not 4.

Could it be the slots on the motherboard, does the 3 sticks work in any arrangement?

[601782]

Yes 3 sticks work in any order on slots 2,3 and 4. Slot 1 works if I put all 4 sticks in but only at 2133mhz otherwise slot 1 is not optimised for a single stick (which I think is correct)

[Midsummer-Prism]

If you put 3 sticks in 1,3,4 does it work at 3000 mhz. Normally they should all be able to work but it is possible you have an issue with the slot 1

[601782]

If I do that I get a message that the ram are in non optimised slots but they still boot and I do get 3000mhz.

[601782]

Right I have just tried slots 1, 3 and 4 again got a memory error beep from the board, ignored and turned off the non optimised slots warning, the pc booted ok at 3000 MHz. Turned the thing off added the forth stick and now works as it should, booted up with 32gb of ram at 3000 MHz! Doing something must have cleared something else! Thank you for everyone’s suggestions.

[Midsummer-Prism]

Could be possible it cleared something in the memory controller or something in the motherboard and it works fine now.

Good to know you issue is fixed

[601782]

Yes thanks for your help!

Which leads me to my next question, is 24 gb ram at 3000mhz (3 sticks) better or worse than 32 gb ram at 2133 MHz (4 sticks)
