Hi,

Can you please help me with the improvement with overclocking current 64GB set.

CPU: AMD R9 7950x
MB: Asus TUF x670e

Thanks,
Stas

 

[GSKILL SUPPORT]

The motherboard has been tested capable of DDR5-5600 with 64GB:

RAM Configurator - G.SKILL International Enterprise Co., Ltd.

Find compatible memory kits for your motherboard. Just select the motherboard from the dropdown list and click on Search for a list of compatible G.SKILL memory kits.

,

The memory kit mentioned does not have AMD EXPO, so you can enable DOCP and set DRAM Frequency to DDR5-5600 to see if it can work well. If not, it may be best to exchange for a kit in the list above.

6200 is good with zen4.

I could share my timings for a similar kit, it's with raptor lake though and it might not be the same die (I might have A-die).

I'm running on 6200 without any issues, also was able to gain M/T up to 6400 but with TCL 32; DOCP I and II work, but I'm trying to overclock RAM to find the best timings.

Are you just trying to boot or are you aiming to get it fully stable?

Just reduce timings and then test for stability, y-cruncher VST and FFT are good for that.

GSkill support,

I can tell you for sure on my system this kit is fully functional, and DOCP I and DOCP II work without any issues. I knew it was on in QLV list, but I was looking for RAM with the lowest timing possible on the market and 32GBx2.

This failed after 6 hours of stability testing (y-cruncher):

DRAM voltage: 1.4
DRAM VDDQ: 1.4
CPU SA: 1.2
CPU VDDQ: 1.2
CPU VDD2: 1.35

The last 3 voltages are specific to intel.

In the Asus Hero Bios, they have memory presets for different types of memory and different capacities... and they work great with my Samsung based memory chips.
You likely have Hynix chips, you will have to find out for sure first, they have presets for them also (And 1 other type, can't remember the name).
I think CPUZ will tell you the on the memory tab, I am using my 5950X DDR4 system right now and can't check.
If your bios does not have them, I can see what my presets would be for your set up, and you can enter them manually. They make a good starting point (Better then XMP or AMD presets) and you can fine tune them further if you'd like.

Is TCL make a big difference in DDR5 as in DDR4?
I see all your TCL's 32 and higher.
This is 1st setting I tried to move down, from CL30 to 28 and this is why I'm not going to 6400 and higher, on CL28 I have no BIOS post.

I couldn't boot with tCL at 30 last time i tried.

There are a lot of important timings, tertiary timings affect read/write/copy a lot for example.

Some progress today.

Very strange thing: in ASUS TUF x670e, the latest BIOS has no option to change CR/CMD2T and no option to disable Gear Mode.

I got 25% better read speed with only a few timings optimized @ 6400 MT/s

I have tighter tRAS (50) and higher tREFI and that's the only timings i see were mine were set for higher performance than yours.

I guess aida64 favors raptor lake over zen4.

intel is faster working with RAM, I have another system i9-13900K with 6600Mt/s TCL 30, and read and writes over 100Gb.

Just basically stock here with a tiny tune, setting the uclck to 1:1 instead of 1:2 and if you have access to change tREFI in your mobo, change it to 65535

I think any other settings I'm changing in BIOS for DRAM timing causing BIOS not to post. This is most I can get (picture was taken not in safe mode)
