Gskill DDR5 6000 MHz and Strix Z690-E XMP problems.
Gskill DDR5 6000 MHz and Strix Z690-E XMP problems.
I own a Strix Z690-E motherboard, a 12900K processor, and a Gskill Trident Z5 RGB (model F5-6000J3636F16GX2-TZ5RK). Four slots, 64GB all in sync. By default, the BIOS runs RAM at 4000MHz. Enabling XMP in EZ Mode during startup forces it into safe mode. The BIOS is up to date. Memtest detected no problems. I can manually adjust RAM speed to 5600MHz and it boots to Windows, but Prime95 crashes after about two minutes. Speeds at 6000MHz work well for hours without issues. Asus told me this RAM isn't recommended for this board—this seems contradictory given the specs that support 6000MHz DDR5. Could there be a compatibility issue or a mislabel? Anyone else experiencing similar problems?
You are running one of the fastest speeds. Calm down. We are still at the early stages of DDR5, and the memory controller on the CPU may not be able to keep up. It's a part of silicon lottery.
Initial adopters' tax. The first wave of anything—particularly a novel platform and a new memory standard shifting from DDR4 to 5—will experience its early challenges. It's normal to notice subpar RAM speeds or performance on the initial release, which typically improves over 1-2 years as the technology matures. This pattern was clear with Ryzen in its first generation and somewhat with the 2000 series. Zen 2, however, saw most issues addressed and resolved.
I'm facing the same problem. Identical board, identical RAM, two sticks work smoothly at 6k but four sticks either use default speeds or fail to post. Safemode takes me through BIOS to reset back, yet XMP2 profile attempts to overclock to 6k with four sticks (64GB) won't succeed. It seems the issue isn't about the number of sticks but rather the configuration. Removing two sticks and returning one kit would help. I prefer 32GB at 6k over 64GB at lower speeds. I adjusted the memory controller voltage from 1.119 to 1.15 without changing anything else. It looks like the four slots might be the problem, not just the GB count. Tried draining the power supply and resetting defaults—changed RAM and memory controller voltages, pulled two sticks, and managed to enable XMP2 at 6k speeds on two sticks.

Hello, I’ve been reviewing a lot of content and owning the rog Maximus Z690 with the same RAM (F5-6000J3636F16GX2 -TZ5 R K) that I purchased on Newegg as a bundle. I recently received two sticks, but it only runs at 4000 MHz and can’t exceed that. I updated the BIOS of my motherboard, yet nothing changed. Someone mentioned it should work with XMP2 using two sticks, but it doesn’t. Is there anything I did wrong? Thanks in advance if you can assist me. I’m doing my best to help!
A general guideline when boosting performance: the memory controller manages better with smaller amounts of RAM at high speeds. Running 32GB or two sticks is usually advised, a practice dating back to DDR1. Asus also offers boards featuring just two slots, emphasizing memory overclocking—known as APEX units. They’re powerful but come with a high price tag.
