Z790 Pro RS with 256 MB RAM ... I'm looking for a 256MB RAM kit (4x64) but can't find anything. The RAM specifications on the website say the maximum RAM supported by the Z790 Pro RS with RaptorLake is 256MB, but the list of supported RAM modules doesn't show any 256GB ones, only 192MB ones. Can someone help me find those RAM modules? Regards |

For RAM compatibility it's always best to check the compatibility page on the RAM's webpage. The support lists from motherboard manufacturers almost never get updated. It makes sense, once the product is launched it doesn't make financial sense to keep testing and verifying every single RAM module that becomes available. With as many board models as there are it would take an incredible amount of labor to do. RAM manufacturers are far more numerous so it's easier to let them test a selection of boards with each of their RAM models than to test potentially hundreds of new RAM modules every few months on dozens of board models for each platform, not to mention older platforms. A quick look at GSkill's 256gb kits shows no kits listed with support for intel platforms at all, from any brand (ASUS, MSI, ASRock etc). For now I would avoid 256gb kits on your system, at least until more are certified for Intel's XMP architecture. Every kit I found only lists AMD EXPO support, a good indicator that it won't work on Intel systems or it would list EXPO AND XMP support. https://www.gskill.com/product/165/377/1750123304/F5-6000J3444F64GX2-RS5K" rel="nofollow - here is a 2x64gb kit from GSkill with XMP support As you can see https://www.gskill.com/product/165/390/1750730814/F5-6000J3244G64GX4-TZ5NR" rel="nofollow - here the 4x64gb kits only support EXPO. Your best bet is to either wait and use a smaller kit for now or check Redit/google for anyone else who has successfully run 4x64gb kits on a Z790 board. -------------
