Memory Latency should be lower?

PC specs in signature. Timings from Ryzen RAM Calculator. Ran a stress test for a while with no errors.
Also played Warzone for hours with no issues. I just feel like things could be better that maybe somebody with experience in memory overclocking might see.

I also can't get it to run at 3800mhz and 1900 fclk no matter what the timings are. I know my CPU can run 1900 FCLK because I was running it for quite some time on my other ram kit.

New kit is also Samsung B-Die

Old RAM kit was G.SKill Trident z Neo CL 16-19-19-39 running at 3800mhz / 1900 FCLK

F4-3600C16D-32GTZNC

New RAM is G.SKill Trident Z Neo CL 14-14-14-34 Running at 3600mhz / 1800 FLCK and at timings posted below.

F4-3600C14D-32GTZNA

Appreciate any input!

I have no extra programs running or open. I just ran it again to be sure and got 58 ns.

When I first got the kit installed, I ran it just with XMP and it was at 66 ns! I will try again just to make sure nothing funny was going on.

I would think even just at XMP this kit would have had me below 60 ns before tuning.

I am on Windows 11 but I think they fixed those issues already?

Yes you should be at around 57-58 before tuning.

They said they fixed the issue but I still wouldn't trust it 100%. There was multiple fixes issued afaik. Also I think you need latest amd chipset drivers for the proper compatibility with 11 so ensure that is done.

11 would be my guess. Nothing else makes sense.

I have the latest bios and chipset installed. I switched back to XMP and here is the results.

Did you reset CMOS after installing the new kit to let the memory train?

Should easily be able to do 3800/16 and most likely 3800/14 on the new stuff.

Yes CMOS has been reset a few times. That was my thoughts as well.

I thought for sure I would be able to still run at 3800mhz on the new kit with much tighter timings. Was not a cheap kit so rather disappointed in the results.

Might have to give that a try. Almost tempted to put Windows 10 back in and see if that helps any.

Put Windows 10 back in. Not much changed really.

RAM at XMP 14-14-14-34 @ 3600mhz = 60.6 ns

RAM at tuned 14-13-13-26 @ 3600mhz = 57 ns

So Windows 10 looks to be roughly 1 ns faster than Windows 11. I still feel I should be lower with my setup.

Here is the latest result. A little better but still not where it should be in my opinion. Also still annoyed this kit won't run 3800mhz when my cheap kit was able to just fine.

Mine won't run 3800 with 4 sticks, but it runs 3733 fine and always has done. Try yours at 3733. Ryzen cpu's do have a memory hole and it varies from one cpu to another.
For instance, mine has always refused to run 3800 at 1:1 with 4 sticks but will run fine at 3800 and beyond with 2 sticks. Your ram is Dual rank, so may well have the same issue as me even though you only have 2 sticks.

The RAM I ran at 3800mhz was also dual rank. I posted the kits in the OP. I haven't really messed with the frequency to much. I get errors pretty quick with just XMP and setting it to 3800 mhz. My cheap kit ran at XMP and set to 3800 mhz no problems.

So I just been focusing on lowering the timings as much as possible. Though it might be a waste since AMD does not seem to benefit from RAM overclocking like Intel.

Let me specify that I'm talking for gaming. In particular Warzone, where intel users see a massive jump in fps from overclocking their RAM. AMD on the other hand does not really seem to gain much of anything as far as gaming performance goes.

I mean, just from going from 3600mhz 16-19-19-39 XMP to a better kit with 3600mhz tuned 14-13-13-24 did not seem to gain me much of anything. So from what I have seen others say, and my own experience I'm not impressed.

Good to hear. What voltage are you applying to memory?
It's at 1.45v. I could get more out of it if I upped the voltage to 1.5 but it tends to get over 50c. So I need to find a good cooling solution before I go any further.

I don't know about the G.SKill Trident Z Neo, but i've had my Team Group 8Pack Edition 2x16GB 3600MHz kit running 3800MHz, CAS14, FLCK1900, 1.5V for over a year.
Its perfectly fine, idle its only slightly warm to the touch. TestMem5 0.12 with Extreme1@anta config it runs without errors for hours. Apparently thats a super aggressive RAM testing program too. Those sticks are rated 1.20-1.40v
I would run 1.5v to try to get more out of the ram but it gets over 50c and will get errors. I already have pretty good air flow in my case. So need to figure out a clean way to get a fan blowing directly over the RAM or something to get the temps lower.

What are you benching / playing to take the ram over 50c and generate the errors? I have an Infrared thermometer laser temperature gun so can try the same. RAM temp idle is ~25c

Inside case looks like this. Front two case intake fans and rear case fan are 'Noctua NF-A14 PWM Chromax Premium Grade Fan - 140mm'
All 3 are locked at 42% to keep noise at a constant level thats not loud but provides good cooling
I test with Karhu and it gets to around 53c in Warzone at 1.5v. At 1.45 it gets up to 47c. Here is a pic of my case. Front has 3 x 120mm intake, 280mm AIO top mount with 2 x 140mm exhaust and 1 x 140mm rear exhaust.

After an hour and half of Warzone memory is 45c (laser temp sensor so not exactly 100% accurate)
Memtest86 earlier didnt seem to do much, but only left it 3 hours. Temp was 29c
I don't have Karhu to test

Very colourful PC!
Lol Yeah I haven't got around to changing the colors yet. So it is currently RGB puke for now.

I use HWMonitor for temps and even at idle I'm around 35c on the hottest RAM stick.
