Unable to upload 4 sticks of 4800MHZ to the XMP profile.
Unable to upload 4 sticks of 4800MHZ to the XMP profile.
Love this channel! I’m working on an 11th generation build and running into a problem I’d love someone to explain. The specs are: Lian Li O11 Dynamic Mini-Tower Case ASUS TUF Gaming Z590-Plus WiFi 6, LGA 1200 (Intel 11th/10th Gen) ATX board, Intel Core i9-11900K, 2 x G.SKILL TridentZ RGB 32GB (2x16GB), 288-pin DDR4 SDRAM at 4800 MHz, Intel XMP 2.0, and a Corsair H100x SSD. I’m also using a Samsung 980 Pro M.2 2280 1TB PCIe Gen 4.0 x4 SSD. There’s an issue with the RAM: when I enable XMP, the four sticks don’t all post properly. Using just two sticks works fine and boots, but setting it to Auto posts them and gets a speed of 2133 MHz. I’m hoping there’s a setting or tweak I’m missing. Thanks for any advice!
I reviewed the QVL and found the RAM model you mentioned wasn’t listed. There’s a very close match on the F4-4800C19D-32GTZR board. It features two 8GB modules of the same type, so it makes sense that a 16GB package would work fine. They probably won’t be able to push it beyond that speed, likely due to overclocking limits.

For boards with 32GB+ RAM, using more than two sticks often causes memory controller stress. Going over 16GB is tough, especially with speeds above 3600. A 64GB setup would need a 4-stick configuration or fewer sticks to avoid issues.
If you want higher speeds, consider lowering the RAM capacity to 16GB or using two sticks instead of four. This reduces strain on the CPU and helps achieve better performance without risking overclocking limits. Modern CPUs usually support dual memory channels, so a quad channel setup works well with 4 sticks at full speed.
Everything is working smoothly at 3600. Two units perform well at 4800. Now I'm trying to determine whether speed or capacity matters more. Appreciate the help!
32GB provides ample RAM for a gaming setup. It rarely exceeds 64GB on its own, which is highly unlikely. For top performance, I recommend two 4800GB sticks if that’s your priority. If it were around 3866 or 4000, using all four at 3600 would be ideal, but with 4800 and four sticks over two, a 3-4% boost is expected. I’d stick with two 16GB units at 4800. You can add the remaining sticks later and switch to 3600 if needed. Unless you’re editing videos or running many virtual machines, 32GB should suffice. For streaming or gaming, it’s more than enough. In practice, the difference between four 3600GB units versus two 4800GB won’t be noticeable unless software highlights minor FPS changes. If you aim for 64GB, 3600 still delivers solid speed.
