How to manually set memory voltage

 · 1. Power on the system and press key to enter BIOS [EZ Mode] 2. Press key and go to [Advance Mode] (If enter BIOS [Advanced Mode)] directly, and then no need to press key again) 3. Click [Ai Tweaker] page as below 4. Click [Ai OverClock Tuner] item and set to [XMP I] 5.  · Clicking DRAM Frequency, and select the clock speed of the memory. DRAM Voltage adjusts the voltage supplied to the memory. You only need to enter the numbers. Please note that although the higher the voltage, the memory can perform a higher clock (theoretically), the probability of memory damage is also greater at a higher voltage.  · The issue I'm having is since I had problems with XMP on a very similar system to the one I built for my friend whether it's better to update their bios and give XMP a try or manually set the RAM timings, voltage, and memory multiplier. Also, if id set the RAM manually what the relation between voltage and MHz is and if I'd need to set the RAM.

Some RAM has several such XMP profiles that are just set of instructions for BIOS to set memory to certain frequency including other settings like Cas and voltage for instance for it to work at. This only applies when manually adjust both SoC and CLDO_VDDG voltages and should be done as a pair. With an SoC voltage of v, the CLDO_VDDG voltages will drop depending on the SoC LLC by roughly ~ 40mv to mv if left on Auto. So adjusting CLDO_VDDG manually you will have to ensure the SoC voltage drop under load is 40mv or less. DRAM: The DRAM voltage is the main voltage for memory, and if you enable XMP then you wont need to manually adjust this. At v most kits will easily reach rated speeds, but you can increase.

It is recommended to set the voltage below V, and at the same time, do not rush to make a large adjustment. For the DRAM Voltage, directly input the value with keyboard. The settings of Advance DRAM Configuration are more detailed, it’s used to adjust the "CL Value" (Timings) of the memory, which is the “latency” period. You may need to change a 'mode' setting to manual mode to enable you to change the core voltage. You should now set the Core voltage to the original value you saw in CPU-z at the start, which in our case was v. This has now locked the voltage to that value, and so it won’t ever go over that (like it may have done during the initial OCCT test). As with LGA and LGA CPUs, keep this value to within V of the VCCIO voltage to prevent long term damage to the CPU. By default, this is V, which means the V used by previous Intel DDR3 memory is still acceptable. However, more recent memory will be rated at V (or even V if you choose a low-voltage kit).
