Question Ram is stuck at 1333 MHz and can't use XMP.
Hello there!
I’m facing an issue with my RAM, it’s stuck at 1333 MHz.
I’ve adjusted the settings on the motherboard, but placing the stick correctly still doesn’t work.
After enabling XMP and saving, I restart the PC but don’t see the BIOS logo.
So I have to turn it off and back on, then I’m told the previous setup failed and I need to put it into default mode to get back online.
I’m really new to overclocking and don’t know how to fix this.
Additionally, I’m seeing low FPS in games, which might be linked to the memory problem.
The RAM I’m using is a pair of Corsair Vengeance XPR 3200 MHz.
Any assistance would be greatly appreciated.
In fact, it seems the system is likely operating at 2666mhz due to its DDR configuration and double data rate. The 9400F platform doesn’t accommodate memory modules running at 1333mhz, since those would be DDR3 and the platform only supports DDR4. What is the precise model of your memory package? Were the DIMMs integrated into a single kit or did they come from separate kits of the same or different models?
Which specific DIMM slots are you using? Beginning at the CPU and progressing toward the motherboard’s edge, 1, 2, 3, or 4? Which ones?
What is the precise model of your power supply, and how long has it been installed?
Hi! The RAM is the same model, purchased in pairs CMK16GX4M2E 3200C 16. The PSU is a Cooler Master MWE 650W V2 and it's not old at all. The sticks are arranged (from left to right in 2 and 4 as I understand).
Yes, those slots fit correctly if they are in A2 and B2, the second and fourth positions.
Nevertheless, Corsair indicates that your system isn't compatible with that motherboard when the CPU is installed.

This doesn't guarantee it will work, but it's unlikely to function properly with XMP enabled without further adjustments.
I recommend beginning by adjusting the DRAM voltage in small increments, testing each change until stability is achieved.
If you need to exceed 1.4v, it's likely not a viable option.
Honestly, Vengeance sticks are subpar. Not to criticize Corsair, but they offer many solid products; however, their memory lines are extremely basic, inexpensive, and frequently change between batches due to different ICs (chips), ranks, rows, etc., while keeping the same model numbers.
This inconsistency is partly due to their branding. Most of their products generally work, and they maintain good support for their items, which usually earns them approval from industry reviewers.
If possible, consider returning the kit or trying alternatives from G.Skill Ripjaws or Trident.
Make sure the product appears on the motherboard's QVL or is marked compatible in G.Skill, Corsair, or Crucial lists.
These three manufacturers are the only ones offering a thorough compatibility database.
They are top-tier brands favored by consumers for consumer desktop memory, whereas other sectors—like enterprise or server—have different standards.
Wow, really helpful answer, thanks a lot for your time, buddy. I actually bought the used computer and have started building things on my own now. I was wondering if the ones I got seemed a bit cheap, lol. The motherboard is from the 9th generation and that’s a big deal because it’s tough to find new high-quality 1151 models unless you go through places like eBay, and the shipping and quality issues add up. I’ve been trying to figure out the BIOS tools, but honestly I’m getting really confused about most of it. I’ll give it a few more tries to adjust the voltage a bit at a time, like you suggested. But probably I’ll just throw it away and get something new. I saw some really cool Trident cards with diamond RGB the other day that made me really excited, hehe.
So, let's make it clear.
LG 1151 is a CPU socket and has no relation to the memory at all.
The type of memory your platform—whether it's a CPU socket, motherboard chipset, or CPU model—supports is DDR4.
However, which specific DDR4 version it supports largely depends on the motherboard and the CPU being used in certain situations.
Compatibility doesn’t require fancy RAM; there’s plenty of decent options available, and often they’re even cheaper than basic memory without heatsinks.
If you're curious about what would work best on your system, you just need to know the country and generally the motherboard model.
Your MS-7B48 is essentially an OEM version of the Z370-A Pro, with most specifications, compatibility, and BIOS firmware matching that board.
In fact, everything could be similar—just a basic Z370 MSI board modified for your prebuilt system.
We can look for more compatible RAM, but it really depends on whether you want to try it or not.
You might consider returning your memory if you purchased it recently and within a reasonable timeframe.
I'm happy to have assisted and that the issue is resolved. Good luck to you, liquid.
