Question Can't enable XMP?

[Hadooken]

Hello Guys,
I recently bought Intel I7 10700K with a GIGABYTE Z590 AORUS ELITE
I have G.SKILL TridentZ Series 16GB (2 x 8GB) DDR4 4266 Model F4-4266C19D-16GTZKW. When I boot my pc it starts on default which is 2133mhz.
So I decided to use XMP Profile to get 4266 MHz and my CPU and I had a black screen after 2 Min it rebooted itself and back to normal ram speed 2133.

So basically because I'm using an XMP profile to 4266mhz is causing my pc not to boot.
Any thoughts about it? like the motherboard not compatible with the ram, or do I need to change the motherboard?

Pc Setup:
GIGABYTE Z590 AORUS ELITE motherboard
I7 10700K
EVGA GeForce GTX 1080 Ti FTW3
Thermaltake 850w Power supply
Silicon Power 1TB M.2
Western Digital 1TB 7200RPM HDD
G.SKILL TridentZ Series 16GB (2 x 8GB) DDR4 4266 Model F4-4266C19D-16GTZKW

All I could find was that your memory used was designed for Kaby Lake Lga 1151. The qvl list from Z590 calls for and shows memory designed for 6th generation z170 chipsets. In your bios when you select xmp did you go down to dram frequency and select 4266 mhz again?

 

[Hadooken]

yes I tried to select 4266 and lower frequency until I got to 3500 Mhz and the same problem won't boot

4266 is pretty high. Not every CPU/Motherboard will be capable of that out of the box. You may need to increase dram voltage, or loosen the timings a bit.

Or you could go for a lower speed with much tighter timings.

I tried all that, it's kind of hard to make it stable and takes approx 1 month, and the result was always zero
i got a lot of errors and crashes
i think the next solution is to change my motherboard with a better one in overclocking with this kind of speed

 

[Eximo]

Or the CPU, that is where the memory controller is.

That ram is guaranteed to reach that speed, stable, while using XMP profile. It's not guaranteed to do so in any particular pc, including yours.

XMP is a generic set of timings. If you think about a Bell Curve, those settings will work for the vast majority of users, out of the box. But that also means there will be a few ppl that will have to manually adjust things to get them to work (low end of the curve) and there will be ppl who can OC well above or adjust the settings/timings well below the XMP settings (high end of the curve)

In other words, it works with most memory controllers easily, but some ppls memory controllers will object.

Try setting xmp, but manually adjust VCCIO/VCCSA to 1.2v each, and dram voltage to 1.38v

I will try it if u have any other voltage suggestions to test it would be great

What BIOS version are you using?

I found VCCIO and down CPU system agent voltage
i set both on 1.2V and dram voltage to 1.38v
same problem didn't boot

What BIOS version are you using?

F4

Update to the latest BIOS as it should have better results.

unfortunately , i updated bios to F5 then F6a, and same problem

also, I tried
Dram 1.45
VCCIO 1.25
VCCSA 1.3
and didn't boot

 

[gskill support]

Stuck at DDR4-3500? Nothing higher can work? How about single module?
