Question Upgraded Ram not at correct speed

[MaddMann]

Hey PC Gamer Folks,

I am running into an odd issue. I recently upgraded my RAM from Corsair Vengeance 32gb 3200MHz to TridentZ G.Skill 32gb 4000 MHz ram. I moved the other ram to my server. However I am finding that I am not getting the speeds, also the speeds seem to show differently based on which program I look at it with. My Mobo (which passes to windows) Shows the ram speed is 2666MHz, CPU Z shows it at a startlingly low speed of 1333.4MHz. I did "overclock" the ram up to 4000MHz, but it caused instability and all my games crashed after a few minutes. So I reset it back to default. Here is my CPU-Z output (Trimmed a bit, but there is a link to the entire read at the bottom

Any suggestions or help would be greatly appreciated. I'm a bit stumped why this isn't working.

You seem to have one more BIOS version ending update, see if getting onboard F10h changes anything for you. Also, 1333Mhz times 2 = 2666MHz, so that's not something to worry about, you're running at base clocks. Manually input the timings, frequency and voltage as shown on the stickered side of the kit and see if that helps.

You should increase the voltage to 1.45v and see if that also helps with maintaining those clocks. Speaking of ram kits, got a link to the ram kit used?

Thanks for the quick reply. Yeah, here is the kit I picked up https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820374106?Item=N82E16820374106

I guess I am a bit lost on this part, The package shows 18-22-22-42, but there are more than 4 settings to adjust. Which items to these numbers apply to? Ignore the 3200 it is now showing, I am still having the same stability issues as I have no messed with the timings at all

BIOS, never using an app, especially not EasyTune or MSI's Dragon center or Asus's utility. Always in BIOS. I'd also try with F10h prior to tinkering with the timings. Once on the latter BIOS version, try X.M.P. If that fails, you can try with manual input.

Welcome.

Thanks, I do adjust in bios, but I can't really take any screenshots in there. Here are some pics of what I have changed after updating my bios (I thought I was on the latest version, but low and behold there def was a newer on on the site)

Thanks again for all your help, now it's just down to testing

 

[Lutfij]

Welcome!

You might want to break out a pencil and a sheet of A4 paper to takedown the timings you see in BIOS, both X.M.P profiles and the AUTO settings. If X.M.P fails, start with setting timings to AUTO and the only thing touched is voltage and frequency, i.e, 1.45v and DDR4-4000MHz respectively.

How are you cooling that i9? Ambient room air temps? Case's make and model and airflow in said case?

 

[MaddMann]

My CPU is closed loop Liquid cool, my video card is just raw dog fans. Ambient temp in my office is usually around 60 degrees, but I have never had cooling issues.

For Now I am giving up on the RAM clocking, after 4 hours of fiddling around with it and never having it steady, I will just run it at 2666, very frustrating for the price I paid, but even putting it at the exact setting, games crash after about 5 minutes of play. Tested using Red Dead Redemption 2, Cyberpunk 2077, Total War Warhammer 2, and Far Cry 6. All crashed within 5 minutes of starting. Reverting back to defaults everything goes back to running like a dream.

 

[Lutfij]

Even if they didn't go to DDR4-4000MHz, did you try with DDR4-3600MHz? The thing with overclocking is that there's no magic number that you key in and it takes off, you will need to perform trial and error runs in order to get to where you want to go.

Another thing is that you should stresstest the overclock with benchmarking app's like memtest.
