Optimize RAM performance to reach its factory specifications.
Here’s a revised version of your text:
My latest setup: CPU – AMD Threadripper 3960X at 3.8 GHz
Processor board – MSI Creator TRX40 EATX sTRX4
Memory – G.Skill Trident Z Neo, 32 GB (two 16 GB sticks) using DDR4-3600 CL16 RAM
Power unit – Corsair HX Platinum 1200 W, certified for 80+ Platinum
Custom build – Icegiant ProSiphon Elite
I purchased two memory kits totaling 64 GB. I installed one kit and placed the sticks in D2 and B2 slots as specified in the manual. The RAM operates at 2133 MHz (speed rated).
I verified the QVL for the board and confirmed this kit supports up to 3600 MHz @ 1.35V.
Attempts to reach 3600 MHz:
1. Activated A-XMP profile – only one stick worked; memory overclocking failed on startup, resetting back to 2133 MHz.
2. Used the Taiphoon + DRAM calculator for Ryzen (v1.7.3). I tried all suggested settings from the screenshot, but none succeeded.
3. Applied procODT up to 60 ohms – still failed to get a stable POST at 3600 MHz.
4. Followed the Taiphoon guide closely, setting frequency manually to 2133 MHz and leaving other values auto. Still no success.
I also consulted the LinuxTechTips article and tried various options: enabling X-AMP with voltage boosts (1.25V, 1.3V, 1.35V), reducing RAM speed from 3600 to 3400, 3200, and 3000 MHz, but all resulted in overclock failures and resets.
The BIOS version is 7C59v15 (released 2020-05-15). The next update is 7C59v164 (beta, 2021-01-11), which I’m hesitant about.
I’m puzzled because the kit was listed as compatible at 3600 MHz, yet I can’t get it to work with my current configuration. Would anyone have any advice? This is my first attempt to push the RAM up to the supported speeds of the motherboard. It’s a bit disappointing that I’m struggling to match the kit’s capabilities.
Feel free to share any tips or adjustments you’ve tried!
I recommend starting slowly with 2400 Mhz, then increasing to 2667 Mhz, and so on. Use CPU-Z or Aida64 to view the SPD profiles. Check the HTML file—it appears only the 3600 Mhz profile is available for the JEDEC sticks, though the ones labeled as "jedec" show peaks around 2133 Mhz. For 2400, 2667, and even 2933 Mhz, you likely won’t need to boost the voltage. Set the voltage at 1.2V for these frequencies and let the timings relax according to the stick’s specifications (like CL18). Once stable, you can adjust further or aim for higher speeds. Officially, third-gen threaders can handle up to 3200 Mhz ECC memory, but in reality they probably support around 3600 Mhz. It might just be that the board isn’t compatible with that frequency.
The XMP profile automatically adjusts settings without manual input. FCLK can remain on Auto unless specified otherwise. Setting DRAM voltage to 1.3 or higher typically results in the BIOS displaying the original voltage, which may vary depending on conditions.
I removed both sticks today and noticed one wasn’t fully seated. I then inserted them individually, and both loaded the XMP profile for 3600 with 16-16-16-36 without issues. After installing both sticks, the profile functioned properly without any changes to slot selection. I ran memory tests for roughly two hours and found no errors or crashes. It seems the problem likely stemmed from a poor initial installation—probably a bit embarrassing. I even re-seated them during the first install because they felt loose. Clearly, my work wasn’t up to standard. Now I’ll try the next kit and avoid making the same mistake.
