RAM underclocking?
RAM underclocking?
Hi
Please forgive if I posted in the incorrect forum.
I just installed two 8 GB G-Skill TridentZ 2666MHz DDR4 modules on my motherboard, but the BIOS only shows them running at 2400MHz and states XMP isn't supported.
On the other hand, when using Corsair Vengeance LPX 2400Mhz DDR4 modules, the BIOS reports full 2400MHz and XMP is available.
Could anyone explain the difference? I'm a beginner in overclocking.
I understand the CPU can't be overclocked.
Model: MSI H310M Pro M2 Plus
CPU: Core i3 8100
Thanks
According to the MSI website for i3 processors, the maximum supported speed is 2400, independent of the actual rated speed of the memory. This likely relates to the memory controller integrated into the i3 and the 310 chipset. For other i-series chips, 2666 is the maximum rated by the board. If you used, for example, 2133 memory, OCP/XMP can help reach 2400 or 2666. The manual specifies a maximum speed of 2400 for the i3 as well. DDR4/3/2/1 will adjust to the slowest device, so the memory controller sets it to 2400, which is what the RAM must support.
This indicates compatibility only with the correct processor installed.
the memory controller is integrated into the CPU. the correct CPU corresponds to the appropriate memory controller. the motherboard chipset offers some assistance, though certain chips (CPUs) provide greater flexibility. the K series is designed for overclocking, so the memory controller can be more adaptable and handle faster RAM when paired with the right motherboard chipset. the motherboard you own is quite basic. on the other hand, there are boards intended for K series CPUs, featuring a chipset that matches their capabilities, with prices that align with the system requirements.
the only unclear point is the one left unasked.
Thank you once more for your response. Not being a gamer, I haven't really been interested in OC. I purchased this basic board along with my main desktop just to experiment with Linux and for its compact size. I enjoy crafting these see-through, minimalist cases from acrylic. I must admit, I bought the RGB RAM mainly for the aesthetic lighting effects, but now I realize I could have saved money on speed. These components might be useful for a future project, perhaps.
I became curious only after noticing the RAM wasn't operating at full capacity. I understand it better now.
