Asus ROG Strix Z790-f GAMING Wifi II, Bios, XMP

[MadMaxG60]

Bonsoir,

J’ai un souci depuis que j’ai ajouté de la mémoire, pourtant identique aux premières.

Ma gonfig :

ROG STRIX Z790-F Gaming Wifi II

Intel 14900 KF

Corsair 4x24 Gb 7200 (D548GB 7200-36 Dominator Titanium bk K2),  (CMP48GX5M2X7200C36W, Dominator Titanium RGB, XMP)

Samsung SSD 970 EVO Plus 2to , 2x

Windows 11, 64bits

Bios actuel 1602,

J’avais d’abord placé 2 barrettes 2x24, et je n’avais pas de souci pour activer le XMP

J’ai placé il a un mois 2 supplémentaires, au début cela a fonctionné et puis a commencé à planter.

J’ai fait plusieurs mise a jour le BIOS, ici c’est la dernier version beta, et je ne sais toujours pas activer le XMP, max 4200 au lieu de 7200 (voir 7400 proposé)

J’avais regardé les Spécifications avant d’acheter la carte sur le site de mon fournisseur et la carte mère était certifié pour accepter jusque 8000.

Que dois-je faire ?

D’avance merci pour vos conseille

I would generally avoid benchmarks. They are only synthetic stress tests that are not very meaningful for everyday PC use. You can use them to test stability, but that's all.

Benchmarks are simply bar comparisons -> who has the fastest PC. That's all.

You can also try with the full system to achieve 5600 MT/s, but bear in mind that you will then be restricted in the amount of RAM. That means a maximum of 128 GB according to the vendor list.

If you want to stay at 192 GB, you will be reduced to 5200 MT/s according to the vendor list, but that requires 4 identical RAM modules from 1 kit.

Whether XMP etc. will then work is still a matter of luck. According to the Asus vendor list for your motherboard, it should work, but the RAM controller in the CPU always has the final say.

Thank you for your time.
Yes, for benchmark tests.
I only use them to see how things evolve.
I've never shared my results.
Have a good weekend

As inge70 has rightfully pointed out, it depends on how much capacity you truly need. More always comes with concessions to both frequency and timings.

Purchase a single, validated kit at the density and frequency you wish to run.

Check on the motherboard QVL - for best chance of "plug and play" overclocking, opt for a kit 2-3 frequency bins below the maximum validated frequency for the density you wish to run.

Clearly, thanks to your information, if tomorrow I have to move towards more RAM, I will follow your advice.
Thanks again.
