Question Ram stuck in 1333 mhz and cannot use xmp

[Liquidsix6]

Hello there!

Im having trouble with my ram because its stuck at 1333 mhz.
sticks are placed accordingly in mobo.
I have tried enabling xmp but when i do and save and reboot my pc doesnt even make it to the bios logo screen.
So i have to turn off my pc and on again,and then i am greeted with a screen saying that the previous oc failed and i have to put
it into default mode to get back to a bootable state.
I am a total noob when it comes overclocking so have no clue how to solve this.
Im also experiencing low fps in games that i think is related to the mem issue

The ram in question is a pair of corsair vengeance xpr 3200 mhz.
My setup is
Any help appreciated.

Actually, it's probably running at 2666mhz because it is DDR, double data rate, and your 9400F platform doesn't even support memory modules that run at 1333mhz, as those would be DDR3 memory and your platform supports only DDR4.

What is the ACTUAL model of your memory kit and did both DIMMs come together in one kit or were they separate one DIMM kits of the same (Or different) model?

EXACTLY which DIMM slots are you putting these into? Starting at the CPU and moving to the right towards the edge of the motherboard, 1, 2, 3, 4? Which slots?

What is the EXACT model of your power supply and how long has it been in use?

Hi!the ram is identical and bought in pair CMK16GX4M2E 3200C 16
The psu is a Cooler Master MWE 650W V2
The psu is not old at all.
the sticks are in (from left to right in 2 and 4 as recommended as i understand.

 

[Darkbreeze]

Yes, those are in the correct DIMM slots if they are in A2 and B2, which are the 2nd and 4th slots.

However, Corsair says that your kit is not compatible with that motherboard, with that CPU installed.

That does not mean it CAN'T work, but it's not likely going to simply work with XMP enabled without some additional tweaking. I'd suggest you start by trying to bump the DRAM voltage by the least possible increments, one step at a time, until it DOES achieve XMP stability. If you need to go past 1.4v to do so, then it probably simply isn't going to be acceptable. Honestly, Vengeance sticks are crap. Not to beat on Corsair. They have many good products but the Vengeance line of memory is VERY basic, very cheap, and VERY much changes from one production run to the next as they reconfigure them with different ICs (Memory chips), ranks, rows, etc. while retaining the same model numbers, unlike most other memory manufacturers. WHY can they get away with doing this? Because of the name. Most of what they sell works fine in most cases AND they support their products pretty well, so they usually get a pass from the industry people.

I'd return the memory kit if you can and maybe try something from the G.Skill Ripjaws or Trident lineup if possible. Try to make sure that it is either on the motherboard QVL list OR is listed as compatible on the G.Skill, Corsair or Crucial compatibility lists. AND, those three are pretty much the ONLY memory manufacturers that actually offer a comprehensive memory compatibility list anyhow. That's because they are top shelf brands that are much preferred for consumer aftermarket desktop memory. For other applications, such as enterprise, server or workstation memory, totally different rules are likely to be inherent.

Wow great answer,big thanx for your time mate.I actually bought the computer used and just started building in new stuff myself,and was thinking the ones i got looked pretty cheapish lol.Too bad the mobo is 9th gen and crap because finding new lg 1151 ones are pretty hard unless through ebay and the costs that comes with it with shipping and quality uncertainty.I have tried understanding the bios oc tools and honestly get very confused with just about everything.Will try a few times more to raise the voltage as you say,little by little.But most likely i,ll toss em and get new ones,i saw a couple sexy trident with diamond rgb and stuff the other day that i started drooling over hehe.

 

[Darkbreeze]

Ok, so, let's clarify.

LG 1151 is a CPU socket, it has nothing to do with the memory at all.

The memory your platform (CPU socket, motherboard chipset, CPU model, etc.) supports is simply DDR4, although WHICH DDR4 it supports is entirely dependent, for the most part, on the specific motherboard and which CPU is being used in some cases.

It does not have to be "fancy" in order to be compatible or even "good". There is a lot of "good" RAM that is not all that fancy. And in fact, often it's even less expensive than "plain" memory with no heatsinks.

If you would be interested in trying to figure out what would LIKELY work fine on your board, just need to know what country, and generally what motherboard although you need to know that your MS-7B48 is really just an OEM version of the Z370-A Pro. Pretty much everything including specs, compatibility and BIOS firmware are going to mostly be the same as that board model. In fact, ALL of it MIGHT be. It's really just a basic Z370 MSI board that's been slightly modified for the prebuilt system that you have. Certainly we can find more compatible RAM but honestly, it just depends on whether that is something you even want to try to do or not. You should be able to return your memory if you bought it within a recent and reasonable amount of time.

Update.
I replaced the ram in question to a pair of Gskill Trident

F4-3200C16D-16GTZR​

and i can utilize xmp now and they are at full 3200 capacity according to bios and win 11.
So anyone having the same problem do the same.
The fps problems i previously had in games is totally gone now too after the change.

Well, I'm glad I could help and that you got it resolved. Best of luck to you liquid.

Thank you for pointing me in the right direction
