[SOLVED] G.Skill TridentZ RGB 16GB DDR4-3000 cannot work on new mobo at 3000

[athinamj]

Hello I just bought the intel i5 10400 paired with Asus Tuf Gaming Z490 motherboard. After checking the motherboard's memory compatibility list I chose G.Skill TridentZ RGB 16GB DDR4-3000MHz (F4-3000C16D-16GTZR). However, RAM cannot work on 3000mhz but on 2800 maximum. I have installed the latest bios update, tried XMP1 and 2 with no success. Since the cpu and motherboard are new can you give me any solution to be able to make the RAM work on 3000?

Have you tried setting it to manual and changing the freq and voltage yourself?

 

[athinamj]

Yes, it only accepts up to 2800 mhz even after changing the voltage.

 

[Mooons]

Explain doesn't accept it? or Not stable?

 

[athinamj]

It fails to start correctly and returns to bios default settings.

Now, I haven't read up on the 10400, but assuming it's a non-k version, that means it is limited to a maximum of 2666MHz.

I reiterate, I have not yet read up at all on the 10400, I could very well be wrong.

 

[Mooons]

Okay so unstable got it.

Are you using correct 2 & 4 (or A2 & B2) slots?

 

[athinamj]

This is valid for the H and B motherboards not for the Z490 ones.

 

[Mooons]

The highest officially supported memory speed is 2666 MHz, but with overclocking (and the right memory modules) you can go even higher.

Yep it does look like it only supports up to 2666 without overclocking.

Well, loading XMP for 3000MHz, what does it set your VDIMM to? 1.2V or 1.35V?

 

[athinamj]

The particular RAM is 3000Mhz and I set it to 1.35V

 

[FoxVoxDK]

Go ahead and bump it to 1.4V.
What does your motherboard set your VCCIO at?

 

[athinamj]

I will bump it to 1.4V and let you know.

 

[FoxVoxDK]

I'm probably going to get called to work shortly, so here's what I can think of as of right now:

VCCIO & VCCSA try bumping each a few ticks over original voltage, no more than 1.15V on either, it shouldn't be needed for these frequencies.

Try yanking both sticks, only insert one in the second DIMM slot from the CPU and out.
Load XMP, see if it works. Try each stick solo. Might be a dud. Try different DIMM slots, for giggles.

VDIMM shouldn't need more than 1.45V and is already pretty high for these frequencies.

@Jay_dog I probably have to peace out shortly(work call), can you throw up ideas if I'm not here? Sorry, and thanks.

Yeah I'll see if I got some more ideas!

Go ahead and bump it to 1.4V.

It didn't work I will try the other options and let you know

Open an incident with g.skil support.
ram faster than 2666 is technically overclocked ram.
The xmp setting is what gets you there.
With new motherboards, there is usually a period of frequent bios updated.
Many are ram compatibility issues.
The latest update came out 5/20

No worries, right here to help.

Try testing each module to see if both have same maximum results. Each should work fine with XMP Profile alone.

Are you using the grey slots, A2 B2?
