This XMP profile isn't updating at 3600Mhz.
I need some advice here. I purchased a G.Skill Trident Z Neo 3600 14-15-15-35 32GB (4x8GB) kit, obviously from the B-Die side. My aim is to push it overclock to 4000Mhz for regular use. Here are my details: CPU – AMD Ryzen 7 5800X, motherboard – X570, RAM – as mentioned earlier. Initially, I managed to reach a clock speed of 2000 with a SOC voltage of 1.15 and left the MCLK at 3600 because I just wanted to test booting. But after that, nothing was working. I then tried manual overclocking, setting both FCLK and MCLK to 4000/2000 and leaving all timings on AUTO to see what would boot. So far, nothing has worked. For voltages, I pushed the SOC up to 1.2V and the DRAM to 1.465V. I also tried turning GDM off and on, CommandRate at 1T and 2T, and even disabled Fast Boot hoping for better memory training. It seems neither a solid IMC nor the best B-Die kit in this range has given me a chance. Maybe I’m facing a tough situation or got a really subpar chip? Any suggestions would be greatly appreciated – thank you!
Expect around 4 sticks at 4K resolution, but it might not be feasible. Try aiming for 18-1900 MHz and adjust accordingly. A stable CPU running at 2K clock speed should handle 4 sticks at 4K without issues.
It might still be possible your infinity fabric can't handle 2000mhz, leading to instability. Could you clarify the timing settings at 4000mhz? Are those specifications compatible with the 3600Hz rating? I’ve noticed auto-timings rarely succeed in OC mode. Also, it seems your overclock stability drops around 1:2; it doesn’t hold steady there. I’d suggest testing the overclock at 3800mhz first, since most 5000-series clocks operate at that frequency and reduce uncertainty.
The main issue is ensuring proper synchronization. Not all configurations can run at 2000MHz with FCLK, UCLK, and MCLK aligned. To reach higher speeds, you may need to adjust timing parameters. Start by enabling XMP 1, which might be causing instability. Set your clock speeds to match FCLK, UCLK, and MCLK, then increase VDDG IOD to around 1050mV or 1.05V, and optionally raise VDDG CCD to 1V. If needed, boost VDDP as well. When testing, run SSE OCCT for an hour or listen to YouTube for stability. If successful, proceed with tighter timing. Otherwise, you can manually relax all settings. Keep the vSOC at 1.15V and avoid exceeding it. Use 1.5V on your vDIMM or DRAM if safe (24/7 use between 1.5-1.6V). Monitor internal temperatures—above 40°C may cause errors. Maintain a 1T Command Rate and enable GDM.
Yeah but I need 32GB of RAM for AE/PS/Premier - also would probably lose out on more performance due to 4-rank vs 2-rank. Will definitely try out 3800/1900 though - probably just got too excited when I received the kit and went straight for 4000/2000 Thank you for your advice!
My 5900X holds steady around 1900, it handles 2000 but starts shaking at 1933 and beyond. The 5600X is stable at 2000 but fails at 2033 and higher. I’m able to benchmark at 2100 with a 1:1 ratio and a bit more on the MEMS if I adjust the voltage. These units are very sensitive, so you shouldn’t rely on fixed voltage settings.
I’m hoping so. I understand 2000MHz FCLK isn’t assured on the 5000 series, but many others have achieved stable 2000 FCLK with 5800s. I didn’t get lucky with bad silicon. I left everything on AUTO, expecting looser timing, but it didn’t work as planned. I’ll test this tomorrow. Probably overreacted when I got the kit and skipped the steps—went straight for the 4000 mark instead. Thanks for the feedback!
It's tough to decide between single and dual rank; you need to push hard. You might find success by switching to 2T with GDM off, though it won't make much difference. Actually, achieving strong results with 2T and GDM off is possible. To reach over 1900 I have to use two sticks. My RAM has reached 4200 MB with a lot of voltage, which isn’t too bad. It wasn’t stable there, but it was enough to finish. I could keep the speed steady with c15.
Your 4x8GB modules are probably single-rank units. Most 8GB DIMMs fit this setup. The count of four sticks versus two per channel still works fine. You likely have the optimal configuration with your four 8GB sticks. Verify your FCLK separately, then assess memory speed using loose timings at 1600 fclk, adjust timings carefully, and test each component individually to identify what’s limiting performance. A 1.46v requirement for 4000MTs might be low depending on the clock speed; 4000CL14 kits from Samsung Bdie, for instance, support an XMP voltage of 1.55v. If both operate stably at 100%, you’ll usually need to reduce the clock speed slightly to maintain stability. This is essentially a delicate balancing act near the stability threshold.
