my ram working with less speed

[alidiaa]

hi i just get new setup and its
rtx 2080 super black
ryzen 7 3800x
Patriot 16GB Kit (4 X 8GB) 3400 MHz (PC4-27200) Viper 4 Series DDR4 2400 MT/s DRAM (PV416G340C6K)
the ram is working way bad then it should be i have 4x8gb ram and it work on 1066mhz
even with xmp
i try to overclock it but it didnt work out with me what should i do to make it work better then now?

Full system specs please.

And how are you reading that speed? If it is something like CPU-Z, then that 1066 is really 2133, which I'm guessing is the case since 2133 is the basic DDR4 JDEC speed that most motherboard default to.

yes with cpu z but still even when i run xmp its the same and when i make the mhz up like to 3444 only one ram speed change on the cpuz also the pc keep crashing and there is big dealy on gaming and when i stream i cant even play even i have good pc

When you change the memory speed in the BIOS, the only numbers that will change in CPU-Z will be the number on the Memory tab. If you set the RAM to 3444 in the BIOS, then the only number that should change in CPU-Z is the DRAM Frequency on the Memory tab. Nothing on the SPD tab will change, those numbers never change.

What does the DRAM Frequency read when you enable XMP and change the speed to 3444? It should read 1722. However, I wouldn't be surprised if that isn't stable and you are getting crashes at 3444. The first thing I would try is dropping the memory clock speed to 3200 in the BIOS(1600 in CPU-Z) and check if that is stable.

As @newtekie1 pointed out we need full system spec, motherboard make and model, etc....

Yup without that we cant help him.

Manually set ram voltage in bios to either 1.35v if you want to run ram under the max speed or 1.45v if you intend on running it at full speed. In bios you also have to manually set the ram speed to 3400mhz or the speed you want to run it at, leave the timings on auto and disable xmp, save and restart, once booted shut down, wait 10 seconds and boot, test and let us know if that helps.

Does it run at the correct speed if you only use 2x8GB dimms

To be blunt, I feel this may be an SOC issue and not a VDIMM problem.

Just went through this exact thing with one of my best friend's builds. What Motherboard? If it is an Aorus, it's a slightly known issue with how the XMP profile is used. you HAVE to manually set the voltage, then you CAN enable XMP, but you will likely get better perf by entering ALL the data on the memory timings, voltages, since even the "XMP auto" is verifiably wrong on some kits, but setting it manually to the same value works. Caveat, the tRC value MAY BE WRONG. and MUST be set manually to something different.

This helps a lot with manual settings.
