RAM Timings advice, can't find the settings!?

[NF7-S]

Hi, I'm totally green on this kind of thing...I've been following this guide;

RAM Timings Overclocking Guide with DRAM Ryzen Calculator | NiceHash

And I'm stuck on what to put where in my BIOS. It started off fine with the DRAM voltage, and I think I finally figured a couple more - but I'm stuck with the VDDG (both IOD and CCD) as my mobo only seems to have one VDDG option...and I can't change that to 0.900, anything other than 1 reverts to auto!?

Edit - also, just noticed I can't set the SoC/Uncore to 1.025 - it reverts to 1.020!?

Edit 2 - I have set the AMD SoC/Uncore OC Mode to enabled (I assume I had to?)

Is anyone able to assist with what goes where?

Thanks in advance

Edit, ok - I started off badly, I've now updated the OP - I'm really close just need help with the question in the OP...

You look to be running on an older BIOS.

The recomented values are:

SoC/Uncore 1.025
CLDO VDDP 0.900
CLDO VDDG 0.900

Have you tried the lower values?
SoC/Uncore 0.975
CLDO VDDP 0.700
CLDO VDDG 0.900

Check online what values are safe and if you are happy test them.

I dont understand what you are aiming at. 3200MT/s is stock RAM speed and they will auto to the stock IF. So really you should not need to touch any voltages.

Thanks for your reply.

Unfortunately most of this goes over my head, I understand the BIOS may need updating so I can look into that.

This comes from my thread here;

Upgraded to 3800X & 3070 feel I'm getting a low 3DMark score... | Overclockers UK Forums

This is my setup;

GPU 3070 Ventus 2X OC
3800X with A13X Artic freezer
8Pack XTREEM "EDITION" 16GB (2X8GB) DDR4 PC4-32000C18 4000MHZ
1tb Crucial P1 SSD
ASRock B450 GAMING-ITX mobo

I had a low 3DMark score and it was because the RAM was running at low speed and it was suggested that I could get some good performance gains if I changed the RAM timings.

In answer to your suggestion of lower settings, I can't set 0.975 as it resets to 'auto', I can set the .7 value but again, I can't change the VDDG because it changes back to auto.

I guess the main question at this point is, are VDDG IOD and CCD essentially the same thing? Can I leave that to auto? Or should I just update the BIOS and see what happens regarding the RAM options?

If you update your BIOS you may get the two options VDDG IOD and CCD. My Asrock motherboard did. You should only update a BIOS if you really need to, you can brick the motherboard if the BIOS gets corrupted when updating. The same thing happened on my asrock motherboard, could not set 0.7 as it would not go that low.

Nice RAM kit btw. You should aim for an IF of 1900MHz and a RAM speed of 3800MT/s if that is stable. You need to do a bit of reseach into the different timing and what settings to use. Starting here could help https://github.com/integralfx/MemTestHelper/blob/master/DDR4 OC Guide.md

Thanks, my mobo has a top RAM speed of 3466+ (OC) - hence the lower setting and looking at the timings.

I think I'm a bit out my depth - I had assumed (and the guide implies) run a RAM test, go into BIOS and change settings, reboot and away you go.

I would have thought at this stage if I leave the one I can't change to auto then it shouldn't do any harm and if there is an issue I can reset the BIOS?

Not sure it's worth reading through that link you sent (although I do appreciate it!) - I mean, what's the best I can hope for as far as improvement % on my system vs time and effort?

Edit @zx128k (nice name BTW ) - I read through the guide, this seems doable (it's much like my old beginners guide to OC - nice easy steps). My only question is that I'm still going to have issues with certain aspects of this overclock...also, what real-world gains can I expect? I was hopeful of a quick and easy upclock - seems there's some good gains to be had bar this one setting I can't set! lol
