Wait, to replace actual DDR5 6000-32 (AM5)

[ir_cow]

O the Hynix M-die definitely needs more than 1.35v... 5800mhz is now 100% stable with 1.37v.... Going to try 1.4v and 6000mhZ

Yeah, CL 30 @ 6000 probably needs 1.45v for M-die (2GB)

Hello,

My PC is :
KF560C32RSK2-32 (that i would upgrade when/if DDR5 became improved, signle/dual rank.......?)
7800X3D
B650E-E
4070ti
1000w shift

About the RAM:
... i think about to upgrade to the best possible sticks (2x16), sooner or later... when/if there will be DDR5 that could really be better, for this computer setup specifically (CPU)...
... so, i ask you what are the important specs in PDF page (url of my sticks) ?.. and how much time should i wait (if needed) to be sure to grab improved DDR5 all in all compard to my actual ones ?
I search the best/perfect sticks for this setup, that's it... also there is the XMP/DOCP thingie, actually XMP didn't bothered my MB, i think, even, it's a full AMD (not the GPU btw) !

i really don't understand even one thing about RAM memory, i need to be advised

Based on a 7800X3D !

Check using Hwinfo whether yours is A-die. If it is, you already got as good as it needs.
Unless you want more capacity, just stick with this kit and go into bios and change some RAM timings, boom, free upgrade.

Heck even if it is "just" M-die, you still good to go and tweak those RAM timings.

I look at that, but i even opened a topic bc OC is beyond my ability, in all ways (anyway):

Clock CPU (7800X3D)

Hey, i just don't understand anything to O/C, just read the last topic and found about : SoC 1.2v - (yes, i know where to set it) -30 CO - (Curv Opt) 1.12v is good voltage for all core load at 5.1GHz -4mv per digit (what ?) //OR// PBO+200 -20 CO // OCCT for stability verif. Sorry to...

last time i enabled DOCP (XMP) Win11 thinked my NVMe was an USB and checked drive at boot, never seen that others times.

BIOS is 2412 (AM5 PI 1.1.0.2b)

If you are comfortable with bios setting and to clear cmos if need, you can start keying these values to tighten up your RAM.
For those numbers in boxed, suggest you key those outside values in place first, they are looser and more likely to post.

RAM speed doesn't matter with a 7800X3D, unless you want to chase the last 1-2 FPS at the cost of increased CPU idle power consumption and boot times.

Well, thanks i take note, but i'd prefer O/C CPU's first.

I'm curious what the goal is here - upgrading from DDR5-4800 CL40 to 6000 CL32 is a huge performance difference, but you already have near-optimal RAM for that 7800X3D. At best you're going to spend a lot of money and time trying to dial in and stability-test slightly faster timings to net yourself somewhere between 0% and 3% gain.

If you have money burning a hole in your pocket and just want to mess with RAM overclocking for fun, then don't let me stop you - but as far as I can tell, your RAM and CPU are a great match. Spend the money on sorting out your storage which looks (from your system specs) to be a massive hodge-podge of small, presumably older drives with low-density spinning rust in decade-old capacitities. Grab yourself a 4TB high-end NVMe drive and call it a day. Buy a 2.5GbE NAS and a 2.5GbE switch and get that storage shared among all devices you use at home, not just the PC. I dunno - these are just suggestions but the RAM you have is the speed I would buy myself for a 7800X3D.

I thinked it was old RAM, but i seen build date is from 2023-11 in HWinfo, so i made a useless topic, i really thinked it was verry early DDR5 sticks.

My ram can do 6000 MHz with EXPO, but I'm running it at standard 4800 MHz because it lowers idle CPU power consumption by 10 W while having no visually detectable effect on performance.

RAM speed is massively overrated, especially with an X3D CPU.

Yes that's what i think, that's why i asked if there exist verry good RAM sticks (found only this could beat mines), but looks mine are near the best from what has been said, then the only thing i have to do is understand how to find the CPU'(s good way to O/C (i say O/C but it's more "find sweet spot") for a better efficiency ans heatness, LLC, PBO, CO-30 thingies but i will fail on my own, so i opened an topic :/

That's why I said that it doesn't matter how good or bad your RAM sticks are.

The 7800X3D is a very efficient chip even at stock. Just slap a good cooler on it and call it a day.

RAM speed doesn't matter as much.

The performance of memory is always relevant, even on systems with large cache. After all, it's only ~100 MB of cache.

My ram can do 6000 MHz with EXPO, but I'm running it at standard 4800 MHz because it lowers idle CPU power consumption by 10 W while having no visually detectable effect on performance.

RAM speed is massively overrated, especially with an X3D CPU.

You have a 3440x1440 144 Hz monitor with an upper mid range GPU, meaning you likely won't notice much better average FPS with a faster RAM tune since you're GPU limited anyway and 144 FPS is not challenging even for non X3D chips.

For someone looking to increase their min FPS and also reach more ambitious FPS targets, such as 240, 360 or even higher Hz, I can assure you that RAM tune will make a significant difference, even with X3D. Not to mention general productivity apps which don't benefit from the cache that much.

While I agree that chasing MT is generally pointless on AMD, reducing the system latency from optimizing memory will mean your X3D chip is actually performing to it's peak, rather than spending time waiting for 4800 MHz DDR5, with a latency that I would expect would be in the upper 80ns range or perhaps higher. With my tune I have ~55ns RAM as measured by AIDA.

This is a simplistic first word latency calculator, it doesn't take into account the other subtimings which are more important on DDR5, but it still shows the relative difference between JEDEC speeds and a good tune ~40% lower latency.

That's that that can help with stutters ? Even "micro"stutters.

Yup. Eliminating potential bottlenecks will help address stutters. RAM is definitely a potential bottleneck, even with an X3D chip.

If tinkering with refresh, I would turn some heating on, place it near PC for the stability tests as trefi stability threshold is affected by temps.

Admittedly though it is a cheap win, trefi in my opinion has the biggest boost of everything thats tunable, including CAS.

It's true that I'm a slow single-player gamer, and my setups are almost always GPU limited, so my opinion (just like everyone else's, I guess) has to be taken with a grain of salt.

Just pointing a fan at the memory will fix most temp issues for daily OC settings. Unless you're going 1.7 V or higher, more isn't really necessary. But tREFI is definitely temperature sensitive, as with most aspects of RAM tuning.
