RAM Overclocking on an H370 chipset motherboard?

[ahmedbatty]

Summary:

I recently upgraded from a Corsair Vengeance RGB Pro 3200MHz RAM kit to an XPG Spectrix D35G 3600MHz RAM kit. I am seeing new XMP profiles in my motherboard BIOS. (more details below)

 

What I Have:

• CPU: Intel Core i5-8400
• Motherboard: ASUS TUF H370 Pro Gaming Wi-Fi
• RAM: 2 x 8GB (XPG Spectrix D35G 3600MHz)
• Graphics Card: Gigabyte RTX 3060 Ti Gaming OC Pro Rev 3.0
• Power Supply: XPG Core Reactor 750W
• Cooler: Cooler Master MasterAir MA410P
• Fans: 2x Be Quiet Pure Wings 2 120mm PWM
• SSD1: HIKVision E100N 128GB M.2 (Boot drive)
• SSD2: Transcend SSD220S 240GB
• SSD3: Crucial MX500 500GB

 

When I was using the Corsair Vengeance RGB Pro 3200MHz RAM kit, I had to turn on an XMP profile to run the RAM at 2666MHz (kit was running at 2133MHz when XMP was disabled) since that is the maximum frequency the Intel Core i5-8400 supports.

 

Now, I have switched to the XPG Spectrix D35G 3600MHz RAM kit (because the Corsair kit died) and I went to the motherboard BIOS to turn on check the XMP profiles and saw the following:

• RAM already running at 2666MHz with XMP disabled.
• There are 2 XMP profile options available now.
• Profile #1 is 3597MHz.
• Profile #2 is 3200MHz.

 

 

 

 

Questions that I have:

• Why is the XPG kit showing these profiles that have frequencies way above 2666MHz? The Corsair kit only showed a 2666MHz profile even though that kit was rated for 3200MHz.
• Will my system be stable on using any of the new XMP profiles? Should I go ahead and use them?
• Should I just leave it just like this and not use any of the profiles?

Go into Windows and screenshot CPU-Z SPD tab. That'll list (most of) the profiles on the module. Generally speaking, the JEDEC profiles will work fine at CPU supported speeds. XMP is never guaranteed since it is an overclock. Higher speed modules may have two profiles, a faster one at the marketing speed, and a lower one in case it doesn't work. Try it, test it.

^^^

didnt know h370 supported ram oc but if it does then try both xmps and see if they work or not

 

3200 and 3600 are pretty damn slow so you should be fine, at worst youll be stuck to the 3200 profile if 3600 wont run for whatever reason

 

for stuff to tweak if the profile(s) dont work look at vccsa/io and vdimm (ram volt)
