Question 3200mhz ram works only 3000mhz

[sonofspardas]

Build new pc spec are
12400f
Asus b660m plus d4
Tridentz F4-3200C16D-16GTZR
nzxt h510 flow

Pc runs perfectly fine while using everything auto in bios dram configuration but as soon as I set xmp 1/2 system doesn't start and bios gets reset tried 3600mhz tried 3200mhz with 1.4v same problem but it's running fine at 3000mhz 1.35 and timing I used was 16-18-18-38 for everything as mentioned on ram box... What to do? Should I return the ram Or is it anything I am doing wrong?

Should I return the ram Or is it anything I am doing wrong?

check your motherboard memory QVL on the motherboard manufacturer product support pages.
if it's not listed it has more than likely been deemed incompatible at it's rated specs.

I would advise against 1.4v unless you want trouble. If you can I would return the memory and get something else.

It supports upto 5xxx mhz (oc)

Yeah that's what I am thinking

 

[JohnBonhamsGhost]

It supports upto 5xxx mhz

the memory QVL lists individual kits that are deemed compatible.
if they are not listed they have usually been determined to not work correctly with that particular board.

 

[Nighthawk117]

The 12400F's official support is for 3200Mhz DDR4 at 1.35v and and 4800Mhz DDR5 at 1.1v.

Bios level?

Just means that kits not in the list haven't been checked and it could go both ways, no motherboard manufacturer can test all existing kits.

@sonofspardas,

what bioss does the motherboard run? The latest has a better ram compatibility.

Version 1003 from 2021/12/30
TUF GAMING B660M-PLUS D4 BIOS 1003
"- Improve system performance and stability
- Improve DRAM compatibility"

 

[JohnBonhamsGhost]

no motherboard manufacturer can test all existing kits.

if any user reports problems to support with a kit that are verified they are removed

Ok will check that

Yes it's 3200 mhz 1.35v kit but unable to run on 3200mhz 1.35v it's running 3000mhz 1.35v

 

[sonofspardas]

Bios level?

Haven't checked it yet. Will update here soon

@sonofspardas,

what bioss does the motherboard run? The latest has a better ram compatibility.

Ohh i will try to update bios then maybe it will work

Okay let us know if it helps. or if you have any questions regarding the update process which btw can be found in the motherboards manual.

Updated bios still same problem. I will return this kit as I have option to replace them

 

[JohnBonhamsGhost]

you may want to barter with the support agent about aquiring a known compatible kit vs just trying another that is not officially supported.

The 12400F's official support is for 3200Mhz DDR4 at 1.35v and and 4800Mhz DDR5 at 1.1v.

you have typo there, CPU ram support always adhere to jedec specs, which is 1.2v for DDR4 even at 3200MHz
1.35v+ is outside of cpu support, intel doesnt even offer paid warranty when enabling XMP profile (going outside of jedec specs)

anyway, not every RAM modules can handle 1.4v, mine cant handle it even if they are samsung b-die (F4-3200C14D-32GTZR), 1.35 works fine even at 3733MHz at CL16 while 1.4v produces ram errors no matter ram clock

as for OP getting ram running at 3200MHz, try first disable XMP profile and set ram clock to 3200MHz (without XMP)
see if ram will be stable or not, if not stable at 3200 JEDEC, return ram

Can you link where you get that from, because i have a hard time believing it.

https://www.intel.com/content/www/us/en/gaming/resources/overclock-ram.html
intel pretty much calls xmp "overclocking for beginners", you can also readup that touching voltages, timings and clocks is ram overclock

aanyway here are papers for 12th gen
https://cdrdv2.intel.com/v1/dl/getContent/655258 look for page 95
DDR4 3200 1.2V
DDR5 4800 1.1V
LPDDR5 type4 5200 1.1v

dont forget to look at page 101 where it shows you what latencies are supported


and if you go through intel warranty papers, youd see that warranty gets void if you touch voltages outside of public specs

Have a quick glance and see nowhere where it says that 3200mhz ram should be able to run at 1.2V ..... which it won't. Think every 3200 kit will show it is rated for that speed with a voltage of 1.35V.

hmm here is one random stick with 3200 @ 1.2v

And to you that says that 3200mhz ram should be able to run at 1.2V? Two seperate nrs combined ...

Good luck with getting 3200mhz ram to run at 1.2V when rated for 1.35V.

it will work at jedec +-CL20 timing
reducing CL = increasing voltage
reducing voltage = increasing CL
thats overclocking basics (as electrons move faster you have to feed them properly)

We're talking XMP profiles here not your imaginary specs.
