Question I have CL16 RAM but CPU-Z shows I have only 18 clocks, not 16 ?

[2k1Sisi]

I have Patriot Viper Steel 16GB CL16 RAM but in CPU-Z it shows I have CL18.
How to fix this?

Memory tab shows what they're running at currently. Spd tab shows profiles, show screen shot of that tab.

Your ram is running XMP - 3602 profile which is CL 18. Not sure where you got CL 16 from but it's running correctly.

all the 3600 are cl 18

It's true my XMP profile shows 3602 and CL18, but there must be a way to edit it because my ram is CL16

Mine is 3200MHz and CL16.. PVS416G320C6

3600MHz not 3200MHz. Confusing yourself . Cpuz doesn't lie and you can't change how it reports obviously.

Then there must be an error somewhere because my ram box literally says PVS416G320C6 which is CL16

What does the actual label on the back of the memory stick show for model number?

It is certainly possible that the box and what was inside the box don't match.

Show photo of the ram module. Box and module do not match.
Probably it was open box or used. You have PVS416G360C8 module there.

Anyway - usually 3600mhz CL18 ram can run in 3200mhz CL16 mode as well.
You just have to adjust DRAM settings in BIOS manually.

But why are you so stressed about CL value?
It would be more important to worry about your ram running in single channel mode.

For optimal configuration you need two ram modules running in dual channel mode.
CL16 vs CL18 is not nearly as important.

I'm worried because i just ordered another 3200mhz cl16 patriot viper, and from what i've heard mixing different specs wouldn't be optimal.

Cancel that and get dual channel kit instead (two modules in kit).

I modified my BIOS settings and inserted my second 16gb ram
Is it all good rn?

Looks fine.
You may want to test ram stability with memtest86.

yup, 0 errors would be ok

Yes, bad.
Latency settings are too aggressive.

Set latencies to 18-22-22-42 and retest.

Tried to change the first one only to 16 and the last one to 36, the result is 0 errors
The majority of errors comes from tRP being 18
Setting it to auto and tRCD to 18 gave me 1 error
What should i place tRP and tRCP to while CAS is 16 and tRAS is 36?

 

[SkyNetRising]

You could try 16-20-20-40.
See, if that passes memtest.

Just tried 16-19-19-36 and it worked with 0 errors
and i have no idea how did i get 2 rams from 2 different stores and it's supposed to be 3200mhz cl16 for both and it appears to be 3600mhz in memtest86
The problem have to be from the main distributor
Anyway, thanks for the help!
