Is it safe to boost your RAM speed to 3200 MHz while operating at 1.36 volts?
Is it safe to boost your RAM speed to 3200 MHz while operating at 1.36 volts?
Here is a concise version of your message:
So, I need some quick information about my PC to get more details and better answers. I have an MSI A320M Pro-VH motherboard with an AMD Ryzen 5 3400G and Radeon Vega graphics. I recently purchased two 8GB RAM sticks, each labeled with a frequency of 3200MHz. I checked the AMD specifications and found that it only supports up to 2933MHz. Should I try overclocking to 3200MHz at 1.36V? The recommended setting was 1.35V, but I experienced some stability issues at that level. Will this cause any long-term damage or errors? Thank you for your help.
It's safe enough. DDR. 4 is suitable for 1.6v+. 2933MHz is a confirmed frequency of IMC in that processor, but it can be pushed higher. The main issue I noticed is MB; 300 chipset series have memory bus architecture problems that restrict signal flow from RAM to CPU and back. It would be best if XMP could work even with voltage adjustments.
Usually, memory issues show up quickly with visual problems or a crash test just to identify the problem.
Avoid inserting 1.6 volts into your RAM if you want to preserve its condition over time. Only certain modules are compatible with 1.6 volts and only for specific CPUs.
Using VDIMM voltages exceeding 1.60 V on Ryzen 3000 and 5000 processors, as well as 1.65 V on Intel Consumer Lake series chips, is not recommended. Such high voltages can lead to noticeable or hard-to-detect PHY degradation over time.
Here is a summary of typical ICs and their standard voltage ranges:
IC
Daily Voltage (V)
Extreme Voltage (V)
H8D, H16A, M8E, M16B, S4D, S4E, S8B
Up to 1.55
Above 1.55
H4A, H8A, H8C1, H16C, N8B
Up to 1.45
Above 1.45
S8C
Up to 1.35
N/A2
The voltages labeled as Daily Voltage are considered safe for their respective ICs, provided temperatures remain stable. Extreme Voltage values may not cause degradation but should be handled carefully. A RAM fan is advised for these higher voltages.
Above 1.45 V has been linked to instability on H8C. Proceed with caution.
S8C tends to decrease in performance when voltage rises. It's best to keep it at or below the maximum daily voltage.
Always adhere to your hardware's safe limits. I currently have 1.475 volts on my B-die (S8B), which is below the 1.6 V threshold. My original kit supports 1.45 volts, making 1.6 volts an extreme value. Ensure you use modules that match your CPU requirements.
At 1.5 volts with tightened timings, my setup can become unstable even with a fan on and off. Lower timings at 1.475 volts maintain stability without random failures. It's unclear whether the issue stems from the CPU or RAM, but multimeter readings remain reliable for RAM DIMMs between 20-30°C. Excess voltage isn't necessary; top RAM modules also offer superior cooling.
Intel XMP Extreme voltage limits stand at 1.5v for DDR4, but it's advised to maintain 1.4v or below for regular use. Unless you're aiming for extreme world record attempts with liquid nitrogen cooling, avoid the 1.4v+ range. A voltage of 1.39v or lower is safe for everyday use. There are exceptions, like Darkbreeze's RAM, but those are uncommon. The standard XMP setting is typically 1.35v.
XMP, DOCP, AOCP, EOCP are general OC settings for RAM with speeds above the default memory controller rates. As a universal approach, it sometimes doesn't suit every CPU and motherboard combination. Some memory controllers may require a higher standard XMP setting of 1.35v or even 1.36v, particularly when using multiple sticks.
If 1.35v proves unstable, opting for 1.36v is completely reasonable. Your CPU might need a bit more than what others use on the same board.
