can someone check for me if this is normal - i bought this ram - https://www.corsair.com/ww/en/Memory-Size/Vengeance-PRO-RGB-…
this has a CL of 16 right?
When i run cpu-z it says CL of 15?
also i purchased - https://www.corsair.com/eu/en/Memory-Size/vengeance-lpx-blac…
will i have any problems running these side by side with 32gb in total?
You guys are awesome, love being apart of this community.
sorry my noob side came out, i mean CL

SPD Latency
15-15-15-36
The latency is correct.
even though the model number says 16? what am i missing here. thanks in advance
Your DRAM frequency seems to be lower than expected as well- 2132.8 MHz. Is XMP enabled in your BIOS/UEFI?
Also - why do you want higher latency?
Click on the Tech Specs.
Tested Latency 16-18-18-36
SPD Latency 15-15-15-36
SPD is what the RAM has been preprogrammed to run at.
Tested Latency is what it can run at.
In this case, lower latency the better.
As veetor stated above, make sure XMP is enabled to run at 1600Mhz. What is your mainboard?
i know i should want lower latency just wasn't sure if the ram in the packet was the same as the packet
As above check XMP is enabled in BIOS. Usually by default it is disabled.
Also no offence, I don't know what your experience with PC's is, but do you have them in the correct slots?
They've got big problems if they've plugged the RAM into the PCI!
Haha! I did not mean that at all.
He is using two different sets of dual channel RAM.
If the matching chips are not put in the same channel then it could possibly cause the problem.
Just a suggestion.
Look at the next tab SPD. It shows the pre programmed latency options your RAM is capable of. If you enable XMP on the motherboard then it should auto pick the right latencies etc.
ok update, i enabled XMP and it would not work at 3200mhz, but it works at 2933mhz. Not sure if this is normal or if I am being shorted here.
RAM will only run as fast as the motherboard and CPU will let it run at. Its rated speed is just how fast it can go.
i got tomahawk b450 and ryzen 5 2600, any insights on this?
B450 chipset with Ryzen 5 seems to officially support 2933Mhz max without overclocking.

@Spennyrich: Hahaha nah you're alright. This is pretty much the smallest issue you could've run into, and it's not as if you didn't get anything for your money - you now have added headroom if you ever decide to do a little bit of light overclocking, seeing as AMD chips are all unlocked.
I've had issues where my parts physically couldn't fit together, or were incompatible, etc.
@HighAndDry: This is not clear to me… I'm running a 2600X, which supposedly only supports 2933Mhz RAM too, but I'm running 3200Mhz:
Specifically, Gigabyte advertised 3200Mhz ram support:
Support for DDR4 3200(O.C.)/2933/2667/2400/2133 MHz memory modules
All I've done is enable XMP in the BIOS. I've not overclocked the CPU as far as I'm aware. Unless the BIOS has done that while using 3200Mhz RAM?
@[Deactivated]: "Supports" in this context means "guaranteed to work with/at". 2600s and 2600Xs are effectively the exact same hardware, just that the 2600Xs are better binned chips (basically better quality chips, and so able to run faster). That also means 2600Xs are more likely to be able to work with higher RAM speeds - effectively you got (a little) lucky. Enjoy you CPU.
ye your right its not that big, what do you mean by headroom when overclocking? do you mean if i overclock there is possibility that i could hit higher frequency?
Depending on how you overclock the CPU, yes some methods of overclocking will also overclock the RAM. I wouldn't recommend it unless your PC's performance is somehow not good enough, which shouldn't be a case unless you do serious CAD or rendering work, etc.
The speed of the RAM that you purchased is 3200MHz.
