Adjust Micron E-die 3600C16 to 4000+ performance
Hey there, I received this memory kit around mid-2020 and experimented with some overclocking just to see what would work. The 3800Mhz setup performed well on the original clock speeds but struggled at 4000Mhz. Since that didn’t translate much in games, I kept it stable at the stock speed and avoided any worries. Now with faster RAM and DDR5 releases, I’m curious if this board can handle 4000Mhz with decent speeds for gaming at 1080p and 144Hz. I also noticed Micron’s Rev E seems promising for overclocking and it appears to be gentle on the memory controller. Any suggestions on timings, voltage, or tRFC settings for something around 4000Mhz? Would love to know if anyone has a similar configuration. I’ve run an AIDA64 benchmark with these settings: latency 51k, 53k, 49k, 48.0ns; setup/settings 9900KF, 4.7GHz stock Aorus Z390 Elite with 8GB Crucial Ballistix 3600Mhz (19nm die). BIOS is fixed at 1.265v, 47 ratio, no boost, 43 ring, LLC turbo, all c-states off. VCCIO/SA default at 0.950v / 1.050v, DRAM voltage/training 1.35v, not on XMP, just set XMP manually. Memory enhancement settings: normal Stock 3600Mhz 16-18-18-38 tRFC 631 CR1. Everything else auto.
Confirming functionality at 3800 is sufficient. Any timing tweaks afterward will be slower, but you could test 1.175 IO, 1.22SA, and 1.42v at 4000 with default settings to check booting. If sticking to 3800, start by reducing trfc, then adjust io/sa up to 1.0 or 1.1 just in case. Lower tfaw to 24 if stability is achieved.
Thank you for your message. I spent roughly an hour yesterday adjusting the settings and still faced issues at 4000Mhz. I increased voltages to 1.45V on the memory and training channels, adjusted SA/IO timings, boosted tRFC and timings, enabled auto mode, used high-frequency/relax OC with 4500+ settings. Nothing resolved the problem.
At one point, the system got stuck in a boot loop with no video output. I had to reset the CMOS, and fortunately my saved profile loaded successfully. At 3933Mhz it worked, but when I checked with CPU-Z it was running at 3433Mhz. It seems there might be a motherboard limitation or the memory controller struggles with four modules.
I own the 32GB E-die kit, two 16GB modules in a DDR4 3000mhz system. It’s working with a Ryzen 3600 @3800mhz at 16-19-16-16-38-58 with a 1.41v setting. Using Intel builds would push it to around 4000mhz easily with Cas 16. My TRFC is set at 560.
Dude, I have the same motherboard, Z390 Elite, with 2x16Gb Crucial Xmp 3200 Mhz (Rev. E, Dual rank) and 8600k. I can't post at 4000 MHZ under any conditions and voltages—even with DRAM at 1.48v, VSSA/VSIO at 1.38v. I'm fine running these at max 3900 MHz, but I keep getting errors in TM5 Anta777 Extreme despite high timings like 22-22-22-46. I'm stable at 3733 MHZ with 1.45v, 15-20-20-40, and VSSA/IO at 1.25v.
