The Ryzen 3700X is running at 1700mhz FCLK?
The Ryzen 3700X is running at 1700mhz FCLK?
Hello everyone, hope everything is okay.
Here are the details about my system:
Processor: Ryzen 3700X +200mhz PBO, reaches 4200mhz under all core loads such as Cinebench
Graphics: Asus Strix 2080 Ti OC
RAM: 32GB (4x8GB DDR3400 C14, clock speed 1700MHz – I can't exceed that)
Storage: Samsung M.2 SSD, 1TB, 2TB WD
Power Supply: Sony 1200W Prime Gold
Bios: Asus TUF X570 latest motherboard
Upgrades: M.2 SSD, SD card, and RAM
Current RAM specs: Gskill single rank Bdie 4x8GB, rated at 3600MHz (16-16-16-36 MHz)
I've struggled to maintain a stable 1700MHz FCLK with any voltage or setting. Now it's steady at 1700MHz with DDR3400 at 14-14-15-30 MHz. I'm curious if running at 3600MHz with C14 would work, but anything above 3400MHz/1700MHz FCLK is unstable, and going over 1800FCLK at 3600MHz doesn't boot at all.
Do these numbers define the maximum performance of my 3700X? What if I upgrade to a Ryzen 5800X3D? Would it support 3600-3800MHz RAM with 1800-1900FCLK or would multiple sticks still be too much?
Thanks!
MW2 has some issues. It crashes frequently. There are many reports on Reddit about this problem, and it isn't limited to high memory usage or specific CPU types. Since it's a big game, developers had to rely on the general public to help identify the bugs.
The system operates at 3600 with dual data rate settings. The clock should adjust automatically based on data rate, so setting DOCP will configure RAM to 3600 with specific timing values and maintain a balanced clock ratio. Exceeding 1800 would need a faster RAM, like 3800, resulting in a higher clock speed of 1900. Booting below 1800 or at lower speeds such as 3400/1700 is expected. The SoC voltage operates under these conditions.
It's currently set at 1.1v, yet Hwinfo displays 1.08v. A 3400mhz crash occurred in the latest Call of Duty update, though I'm uncertain if it's related to the game or my PC. Other players and streamers are also experiencing issues. I've tested 3600/1800 stock docp without success, but it still crashes in Call of Duty except for other tasks or games since yesterday. I'm trying Samsung Bdie to reach 3800/1900 c16.
Keep in mind that with the Ryzen 3700X the native support is for 3200. Anything above that would require an overclock on the CPU's memory controller. Have you checked if using two sticks could allow booting at 3600? This might be one of those situations where completely filling all the dimming slots is actually the issue.
I would also mention that with four sticks the 5800X3D isn't a viable option due to this:
Max Memory Speed
2x1R
DDR4-3200
2x2R
DDR4-3200
4x1R
DDR4-2933
4x2R
DDR4-2667
This indicates that using four sticks in a single rank still limits the supported speed to 3200. I strongly suggest testing with two sticks first. If it boots at 3600, consider switching to 2x16gb sticks instead of 4x8 or opting for 16gb units. That amount is more than sufficient for most non-production tasks.
Hi
What's the age of your RAM?
Could you get a return?
Was the RAM bought in a 4 stick package or are there two separate kits for 4x8?
If it's not possible to return, the 3400 / fclk 1700 stable might be your best option.
As mentioned before, I believe the 4 sticks were matched or unmatched and the problem lies in exceeding the memory control limit of 3200.
My 2x16 G.skill trident z 3600 handles 16-16-16-36 without issues and can run at 3733 with proper timings.
Lowering to cl14 causes a block when I adjust it.
The 1, 2 and 3000 series Ryzen models avoid using 4x memory modules, and they also steer clear of odd-numbered RAM timings or clock speeds. Ram frequencies must align neatly with a clean multiple of 266, such as 3200 being exactly 266 times 12 or 2933 being 266 times 11. Any deviation can cause instability or boot issues because the fclock should be half of the ram speed. Using four sticks exacerbates the problem, especially in dual rank configurations, where sequential parallel processing becomes problematic. This results in reduced performance as the system struggles to handle the increased load.
I possess a 3800x capable unit that supports 1800 Fabric Clock with a 4xDIMM single rank configuration, which aligns with the standard upper limit. The 1900 Fabric Clock was the point where issues began to appear. When the infinity fabric (Fabric Clock FCLK) becomes unstable at 1800, raising the vSoC to 1.1 volts typically resolves the problem.
Configuration Maximum Safe Speed (Up To)
2 x 1 Rank 3600MHz 4400MHz
2 x 2 Rank 3600MHz 4000MHz
4 x 1 Rank 3600MHz 4000MHz
4 x 2 Rank 2933MHz 3600MHz
Refer to page 11 for details; it confirms you should encounter no difficulties achieving 3600MHz with a 4x1 rank configuration. The 4x2 rank represents the upper safe speed threshold before performance drops to 2933MHz, yet still reaching 3600MHz remains achievable. Some CPUs may cap at 1700 MHz.
SoC (System-on-Chip) Voltage
The SoC voltage refers to the power supplied to additional components, commonly called “System-on-Chip.” Most motherboards automatically adapt the SoC voltage to support overclocking in DRAM. This setting can also be adjusted manually.
Please handle these adjustments with care, as precision matters due to possible measurement inaccuracies. Setting the SoC voltage too high risks damaging your CPU or other parts.
1.2V is typically regarded as the upper safe limit for SoC voltages, especially on Ryzen 3000 processors.
Many motherboards automatically modify the SoC voltage to match your overclocking preferences.
AMD recommends experimenting with ProcODT if booting fails. This parameter controls the processor’s on-chip termination impedance. According to Micron, increasing ProcODT values can enhance RAM stability, though it may require higher voltages. For Ryzen 1000 and 2000 models, aim for 40Ω to 68.6Ω due to weaker memory controllers. On Ryzen 3000 and 5000, 28Ω–40Ω is advisable. Lower values might be more challenging but could ease voltage demands. Higher values may improve stability, as Micron notes. Values above 60Ω are generally only suitable for very weak memory controllers and low-power builds, aligning with The Stilt’s recommendations.
Lowering the SOC voltage or VDDG IOD can enhance stability. For Ryzen 3000 and 5000, increasing CLDO_VDDP can aid stability above DDR4-3600.

AMD suggests trying ProcODT adjustments if you cannot boot. This setting influences the processor’s termination impedance on-chip. Micron warns that exceeding safe limits may cause irreversible damage to your CPU or other components.
Thanks for the updates, everyone. The game starts smoothly at 1800fclk and even goes up to 1900fclk, but it crashes frequently at 1800fclk. I recall it didn’t crash at 1700fclk or maybe the updates caused the issues? It’s unclear if the problem is with my PC or the game itself. For any time over 1800fclk, the PC would randomly restart or display a blue screen, confirming instability with four sticks. Trying two sticks didn’t help at all. My RAM is two identical 16GB units, same specifications, but still failing. It’s the same issue across all configurations.
