RAM Frequency Issues

[GeordieMatt]

Afternoon all,

My wife kindly bought my 4 x 8GB Team T-Force XTREEM ARGB DDR4 4000 MHz RAM for Christmas, whilst my system works it will not allow me to increase my RAM speed from 2400 Mhz and when I do try,the system resets it after trying to boot up 2-3 times. MY System Spces are as follows:

CPU: AMD Ryzen™ 9 5900X
RAM: As above
Motherboard: Gigabyte Aurous Elite x570
GPU: Founders Edition 3070 ti
Storage: 2 x 1TB SSD's

MY query is how can I increase my RAM speed to at least 3600MHz do I need to play wight timings and various other settings as well as manually changing the DRAM value? I appreciate this is not using the full 4000 Mhz but I don't think I will get to that and be stable. I have tried enabling XMP in BIOS and using Gigabyte Easy tune, both options caused the system to try and boot before reverting top 2400 Mhz speeds. The motherboard can take the RAM according to the QVL list but only as a single 8GB stick and not 4 x 8GB so could this be a compatibility issue with the MOBO? So far I cannot see any QVL lists that have 4 x 8GB compatibility and I don't really want to return these RAM modules as they look great and fit my system perfectly.

I would appreciate help and guidance on this but appreciate it may be new RAM is in the order but if I can solve it with help; I would rather do that.

Many thanks

Matt

A lot of motherboards can't overclock the memory to the XMP values when running 4 sticks
4 sticks adds a lot more work to the memory controller so 4 sticks will often only run at stock settings

Using just 2 sticks should work fine at 4000 Mhz

You can't get it stable at anything above 2400?

I'd think 3000 was easily achievable and likely 3200 & 3600, since 8GB sticks are almost certainly single rank.

When you change the frequency, I would just use the board default timings and make sure you set the DRAM voltage too, since it won't boot at 3600 using 1.2v. I don't know if XMP will change other voltages and settings (it might do), so you may want to read up on what other users change to get 4 sticks stable on Zen 3. I don't believe you'll need to make as many adjustments with 8GB sticks, as you would 16GB sticks.

Strangely enough it seems to be stable now at 3733Mhz. I took out two sticks to get them stable and that was simple, enable XMP and boom they worked. I then shut the system down and installed the other two, the bios remembers the settings for the higher spec and now the system seems to work. I will
do some digging into its specs when i get a chance.

If you do any important work with the PC I'd do some stability testing (the same as overclockers do), but if you only play games you can just see if it crashes

I'd do some testing at 3733Mhz because that might not be stable.... I know from my own rig that 4 sticks at 3600Mhz should be fine and matches up with an 1800Mhz infinity fabric (did you change flck on yours to half the ram speed?) happily enough... all I needed to do was xmp on ram and adjust infinity fabric to 1800mhz but then I was running 3600Mhz ram.

I'm sure I read somewhere that 4 sticks seem to max out at 3600mhz....

Make sure voltage is correct. Over the past few years, some kits, when XMP was applied, all timings and speed worked fine but the voltage wasn’t applied correctly.
Even with my last DDR5 kit, works at 6000MHz but I had to set the voltage manually.
Last time using DDR4, was using 1.35V for 3600MHz but the timings for the 8Pack kits are quite low, hence the higher voltage.
At the product’s page, they mention 1.35V. I would try that to start with. Using 4 x 8GB it may work or slightly more voltage for stability, like 1.37V.
Some people may try lower voltage, and may work, but running as spec, timings and voltage, should be gold regarding stability.
