Hey Guys,

A little new to the overclocking scene and having a few issues with attempting to overclock my RAM.

The timings that the calculator spits out don't look to be correct:

2522211


Can anyone assist me with dialing in these settings?

2522212


PC Specs:
CPU: AMD Ryzen 5 3600X
Mobo: GIGABYTE B450 AORUS PRO WIFI-CF
BIOS: 07/13/2021 F61
GPU: GIGABYTE RTX 2070 Super Gaming OC (GV-N207SGAMING OC-8GD)
PSU: Corsair HX850
RAM: 32GB Corsair Vengeance RGB PRO, CMW32GX4M2D3600C18
RAM Rev: 3.44 Micron 16 Gb B-die Rev. B
XMP Timings: 18-22-22-42

2522213


Any assistance would be much appreciated.

Cheers,
Cam

For the calculator to work most effectively, you have to use typhoon burner and export the timings in nanoseconds. Then import before calculation.

i always have trouble finding the settings to export in nanoseconds. I remember it’s at the bottom of a screen in blue a hyperlink though. Hope that helps

you’ll also have to select B-dieunder memory type.

Yeah, I've done that before, by importing the XMP Profile, but unfortunately, it states "Not supported!"

That is the calculator being used correctly, but I cannot tell you if your memory will work at those timings. It looks very reasonable to me.

Edit: I would probably leave everything tRTP and below at their current values (auto?). Setting tWRRD to 1 sounds wrong and there is no need to increase the others.

Don't trust the dram calculator too much. i have 1 set with XMP is 4000 18-22-22-42, dram caculator can't give me parameter of 4000, highest suggestion is 3833 with timing 19.
i have stable overclock at 4000 15-16-15-15-30 with 1.5v
14-18-15-15-29 1.6v
16-16-16-16-32 1.43v

Definitely on the right track and I am curious to hear your results. I have same memory kit as you and I was able to get a quick and stable OC by upping my kit to 3800mhz and setting primary timings to 18-21-21-21-42 with 1.42v. Left all other memory timings on auto. Upped my FSB to 1900mhz.

Might be worth a try but YMMV depending on MB, bios version, CPU.

Good luck!

Do you have the same kit?
If so, that's pretty impressive - would you mind sharing your timings/sub-timings with me?

I've currently got my timings to the following, stable, no errors:

Aida64 Benchmark:

Are those write bandwidth scores real? Why is it so low? I mean, those timings aren't great but that is about half of what I get! The read and copy bandwidth scores are similar too. :unsure:

Are those your auto values for tRDRDSC, tRDRDSD, tWRWRSD, and tWRWRDD? I do get slightly better bandwidth scores with lower values, I would not turn them up from what auto sets them to, no matter what the calculator says (unless it is unstable, of course).

Going tighter than the calculator is not a bad idea, I can run lower than what the calculator suggests, but you need to test both performance and stability and you hit diminishing returns. Those timings do look pretty good from what little I know about Micron B-die. :unsure:

Yes, they are set to Auto for those values.

Wow, you seem to get way tighter timings than me!

But then again, you are rocking a Crosshair VIII Dark Hero x570 and Ryzen 9 5950x.

Your board is clearly better than mine, with greater capacity to Overclock and you have more cores/series of Ryzen that handles the memory differently.

I'm wanting to get onto that exact setup!! Waiting for the prices to come down a little and then take a trip to the US to pick them up.

Can you share your Zen Timings with me, so I can get a better of understanding of how your values have scaled?

I added the timings to my above post.

The exact memory kit is very important too. Samsung B-die can get a lot tighter than everything else. The memory controller on Zen3 isn't much better than on Zen2, though the motherboard does help, especially with four DIMMs.

Ah, I see you have a completely different RAM Kit.
I was under the assumption you were running the same kit, die, etc.
Yeah, Samsung B-Die is obviously gold in that respect.
Thanks for your helpful insight.

Let me know what AIDA64 Benchmark scores you get with this kit.
Would be interested to know if I'm on the right path.

I don't have a license but I ran the trial. Hopefully gives some helpful info!

That is very slow you need to run 1:1

This is running 1:1 1900mhz FCLK So I am not sure what you mean? Was able to bring down CL to 16 stable by upping voltage to 1.45 so 16-21-21-21-42 and getting 62.3ns latency now.
