Issue with overclocking on the latest build?
Issue with overclocking on the latest build?
I assembled a PC using a Ryzen 7 9700x processor, an ASUS TUF GAMING x870 plus Wi-Fi motherboard, and two 16 GB G.Skill Flare X5 DDR5 RAM modules.
Attempted to configure RAM speed with EXPO (6000 MT/s), but it didn’t work. After resetting the CMOS, I manually set the frequency to 5200 MT/s while keeping other settings at "auto," but that also failed to boot. Resetting the CMOS again brought everything back to normal, and the system started up properly on Windows 11 or Ubuntu.
I was hoping to slightly overclock the RAM, but it didn’t succeed. Anyone have advice or should I keep it as it is? The BIOS is the latest version (April 29, 2025).
If 1.40v 6000 failed, it doesn't guarantee 5200 at stock 1.10v would work either. The setup is designed for 1.40v, so testing that first makes sense. You might eventually reach 6000, but it could require a higher commission than what was used at EXPO 28—it's all about experimenting to find the right approach.
How much time should be allowed for the memory/cpu to adjust to the new settings? The yellow dram light remained on for 10 minutes before giving up. After resetting the CMOS, it took roughly 30 seconds to reset and come back online.
If it functions properly, it should appear immediately. However, if it is extremely fragile, it might restart into default settings for CPU and RAM, similar to resetting CMOS without also adjusting other components like CSM or boot order. The issue arises when it is only just stable enough to POST but then crashes shortly afterward—waiting indefinitely would be pointless since there’s no progress being made.
It’s more efficient to begin with a higher voltage and slowly increase the clock speed. If instability occurs, you can adjust the timing parameters or, once reaching your desired clock speed, reduce them gradually. Testing memory stability is time-consuming, so plan to temporarily stop using the PC or consider swapping the RAM for a pre-tested QVL module provided by the manufacturer.
These issues can be challenging to resolve without replacement components. They might relate to DRAM, CPU, or motherboard. Regarding the CPU, none of these are likely, but possible causes include: memory controller limitations, inadequate mounting pressure, poor contact, or damaged pads. The DRAM itself could also be faulty, as I haven’t experienced a failure until building my current setup, suggesting it’s a rare occurrence. The motherboard might have defective slots or socket/trace problems.
It seems the specific part number might be missing from the QVL. Most of the G.Skill 2x16GB 6000 kits shown are XMP, not EXPO, and many are 40CL. There are two EXPO Samsung 36CL models and one Hynix 30CL listed. All units are 1.35v. I thought you might have purchased a CL28 kit since those offer the best performance, but they’re 1.40v and not available on the QVL. If the second set doesn’t fit, it could point to issues beyond the motherboard—possibly a weak CPU memory controller. The 6000 is ideal, but technically 5600 is the maximum supported speed; going over that isn’t covered by warranty. You might still have options if nothing above 4800 works.
