Issue with 4 stick RAM not starting on X570 Xtreme at full speeds
I purchased four 16GB dual-rank cards from G.Skill, rated for 3200 MHz. They don’t perform at the expected speeds. I applied XMP settings but saw no improvement. Updated BIOS didn’t help either. Raising the voltage to 1.4V didn’t work, but lowering it to 3000MHz did. It’s strange since the cards are rated for 3200 and are listed in the Mobo QVL as supporting four sticks. My CPU is a 3950X.
Adjust SOC voltage to 1.1V, placing you at the critical point of the memory controller in the CPU.
performance declines after reaching 1.2V in every case I've observed
Increase the memory voltage even more. Keep in mind that B-die scales with voltage. Also, provide adequate cooling to maintain stability.
It seems you're asking about expected performance improvements when increasing from 3000 to 3200, and also inquiring about the purpose of the rig.
I've managed to reach 3133Mhz using SoC 1.07v and DRAM 1.37v. I even succeeded in reducing the timing to 14-14-14-30 tRC-44, and with more adjustments I expect further improvements. However, the surprising part is that even with maximum efforts, it doesn't boot at 3200Mhz and CL14 stock XMP settings. I've increased the memory voltage up to 1.45 (avoiding higher values for regular use) and tested SoC 1.15, but it still fails to boot at that frequency. I tried different voltages and settings, yet the BIOS doesn't recognize it until I set the frequency to 3200Mhz. It seems the issue might be related to the XMP profile itself, possibly being outdated or Intel-specific. Could a particular timing quirk be responsible? I'm curious about the distinction between regular GSkill Royal and GSkill Neo (AMD). Do the Neo kits come with different hardware, or are the differences just in settings? I've seen others achieve success with Neo kits, even reaching 3600Mhz on a CL16 with 4x16 modules. If it's just the XMP settings, copying them should work easily. But if there are additional hardware components in Neo kits, the situation changes entirely. Locating detailed information about this inconsistency online is challenging; most just claim optimization without clarity on the specifics.
The improvement is minimal, yet it's worth the focus and value you receive. This device is designed for display or gaming purposes.
Settings should remain consistent; however, adjustments may influence sorting since the memory testing protocol could align more closely with Ryzen's memory controller. Tightening timings isn't possible, but this could indicate a memory controller or board limitation. Such issues have been reported with the Gigabyte X470 Gaming 5 and Ultra Gaming models.
