HyperX Predator 4000MHZ (XMP settings inactive)
Hey there! Your XMP settings seem to be causing issues with your RAM at higher speeds. You're using two 16 GB dual sets in dual channel mode, which should give you around 32 GB of memory. Consider adjusting the voltage slightly—raising it a bit from 1.35 might help stabilize things. The blue screen you see when XMP II is active suggests there could be compatibility or power issues. Running just one dual set instead might also work if you're concerned about performance. Let me know what you think!
Consider removing two units first and see if it resolves the issue. If successful, return them and adjust VCCSA and VCCIO to 1.2–1.25 while setting DRAM Voltage between 1.38–1.4. Determine which settings prevent instability without overvolting further. Note that stabilizing VCCIO alone should suffice, but testing is wise.
If you already have the same configuration, including XMP profiles at 3600 and 4000, it seems performance improves more at 3600. I tested only two sticks and noticed this pattern consistently across Intel and AMD systems. It appears they adjusted timing parameters to accommodate 4000, making 3600 more efficient. This holds true even for Prime95 under bandwidth constraints.
It would be a disappointment if this applies to me, especially since the RAM I bought was expensive. However, it seems to work well at 3600.
Hey there! I'm back after some testing. I had a few questions along the way. It took a while to get the 2 RAM kits stable, mainly because of a few beginner mistakes. The XMP profiles didn't work unless I pushed the voltage higher than usual. Eventually, the RAM sticks ran smoothly with manual settings at the following timings: Mode 2 CAS latency: 17 ms, CAS delay: 17 ms, Action time: 37 ms. Command rate: N2 DRAM, V: 1.42 IO: 1.18 SA: 1.25. I ran MemTest86 for 24 hours with 6 passes and didn't see any errors. Would you think it's possible to fine-tune the timings further? They look really solid right now, but any advice would be super valuable.
