Question Gskill DDR5 6000 Overclock to 1T CL28 and fine tuned voltages and timings.

[D007]

Hello everyone.

Please allow me to preface this with that statement that I am no professional but I try my best.
I started this OC by beginning with a guide from here: DDR5 Overclocking Guide: Make it Faster - Overclockers
Then I had to tune the voltages as this alone did not manage to get me stability.
I also lowered some timings until they couldn't go any lower without errors and maxed the frequency with this setup.

So without further ado..
I recently picked up some Gskill DDR5 6000 ram.
Gskill trident Z5 RGB 64gb (2x32GB) DDR5 PC5 6000 48000 CL 30 Dual channel memory.

G.Skill Trident Z5 RGB Series 64GB (2 x 32GB) DDR5-6000 PC5-48000 CL30 Dual Channel Desktop Memory Kit F5 - Micro Center

Its a 2x32gb (64) GB set running in gear 2.
Voltages are 1.49V on both sticks. They are rated for 1.4V.
VDDQ and VDD2 cpu voltages are at 1.4v
VPP is at 1.9V.
Managed to get some pretty sweet timings with these.
1T, CL28 among other things.
Check it out, I hope it helps someone. Voltages are on the right,
I decided to make another pass with memtest pro just because I was testing lower voltages but it has already made over a 100% pass before.
If there is anything I could do better, please let me know.
Thank you.

fascinating. I didnt know people still overclocked their ram.

That's like saying you didn't know people overclocked anything at all IMO..lol
But yes, yes they still do..

well see, over the years both the way memory allocation management works has changed, and also the relationship between ram, bus, cpu and disk has. Sure, if you are trying to beat a world record, you would overclock your ram too, but for normal use, it's such a small gain at the risk of instability. You don't see the same benefits today, that you did 20 years ago, from overclocking ram, so, frankly, i wouldn't bother. At most i would go for a very mild OC, once you find the sweet spot that doesnt need any tightrope walking, that's your OC - that's what the kit should have been rated as to begin with.

We are few and far between, but some of us still manually overclock RAM. Most people just apply the XMP/EXPO profiles and call it a day. Proper, stable, RAM overclocking manually is suuuuuper time intensive. But if you selected the right RAM (pretty much anything Samsung B-Die for DDR4), then you could extract significant CPU performance increases if you manually tightened timings beyond the XMP profile. Manually overclocking my RAM timings has yielded around 10-15% more performance in very CPU limited situations. Mostly games. Some exceptions were 3D rendering and video encoding, which saw much smaller gains.

Is it worth it? Probably not. Overclocking, in general, today isn't as lucrative as ye-olden-days. Especially CPU overclocking. You can't buy the bottom CPU SKU and overclock it 50% to go toe-to-toe with the top SKU. Same with memory. But I enjoy the process of stacking what gains I can get into a cumulatively significant gain.

I couldn't of said it better.

I never think that way about anything.. I think "Hey, I can get 3% here and 4% here and 5% here" and like magic.. I just got 12% all around. Every point adds up as far as I'm concerned but to each their own.

I wish they would produce better kits instead of us having to monkey around with them. I understand that they want the dumpster kits to be affordable so they give them horribly slack timings but if I'm paying north of $300, they better give me OCed experience out of the box without me needing to touch anything in the BIOS. DDR5 just sucks in general. I can't run my EXPO DDR5-5600 kit at anything above DDR5-4600 2T with my 12700K. Either the IMC is crap or the ASROCK BIOS or the kit really hates Intel.

I could not agree more. What I did with these timings was basically an insult for the price I paid..

When I get a chance this weekend, I will run some CPU limited benchmarks and games and post the results. Full mobo defaults, XMP only, PBO only, my manual RAM OC, manual RAM OC + PBO.

Nice! Good ole fashioned leg work right there. I like it! lol

 

[solidsnake1298]

I learned a few things quantifying my results. The 5900X responds a bit differently than the 2700X to PBO. Which was the last CPU I owned, but on this same Asus board. I got some weird regressions with PBO enabled, by itself and with my manual RAM OCing. Maybe some sort of package power limit since I have to increase the SoC voltage for the manual OC. Also, Ubisoft has done a lot of optimizing with R6S. When I was benchmarking my 2700X several years ago there were muuuuuuch larger deltas.

 

[solidsnake1298]

Much learning about PBO on Ryzen 5000 is occurring. I will post some updated numbers Monday or Tuesday. Some early results:

new PBO settings + manual RAM OC
Time Spy CPU: 15403 vs 14704
CB R23 MT: 21914 vs 21050

Been trying to figure out how to do this with my i7 12700kf and the 6000 ddr5 corsair vengence ram I got. Will run in XMP fine but when gaming it crashes.

fascinating. I didnt know people still overclocked their ram.

I have a 5800X3D and a 6950 xt neither of which over clock (at least not better than just letting them do their own things) so my RAM is pretty much the only thing that I can overclock!

DON'T TAKE THAT AWAY FROM ME! 😭

With the 5800X3D, you can still tweak it with PBO / curve optimizer, to get it to run cooler and more efficiently. At least I can with current board and BIOS. If you don't have the option, you may need to update your motherboard's BIOS.

My motherboard doesn't do it, there's a little app that does the same thing and I have that scheduled to run at startup or login. It was a bit of a hot beast at stock and that's with the chip under water!

there's a little app

Something other than Ryzen Master?
