RAM Not Running at Correct Mhz?

Hello all, 

 

I just recently added an additional 16GB of 3200MHz RAM to my gaming rig (for a total of 32GB, all at 3200MHz). And Windows Task Manager, my BIOS, and even CPU-z are telling me that I'm not getting 3200MHz across the board. In addition, my bios won't let me run xmp. It crashes and has me revert to previous settings.

 

The ram I had initially was Corsair Vengeance LPX (2x8) 16GB 3200MHz, and I added Corsair Vengeance RGB Pro (2x8) 16GB 3200MHz. I'm wondering now, if this was a rookie mistake, and I should've just gotten more LPX instead of the RGB? But the MHz is the same, and the latency numbers are also the same. 

 

System hardware is as follows:

Core i7-9700k

MSI z370 SLI Plus

Corsair Vengeance LPX (2x8) 16GB 3200MHz

Corsair Vengeance RGB Pro (2x8) 16GB 3200MHz

RTX 2070 Super FTW3

 

If anyone has any advice on how to fix this, please let me know. I still have time to return and the ram I got and swap it for the same ram I had initially. 

 

Thanks!

The only thing I can think of is the system is trying to be safe because you have two different ram kits. That is the only thing I can think of

this can occur in various reasons. can you try wiht onlu LPX or only with the rgb sticks and run XMP?

of course your system might not like the different models, but my old system ran with them, so there can be a problem with your ram stick too.

 

update bios and other drivers.

Tier lists for building a PC.

 

Motherboard tier list. Tier A for overclocking 5950x. Tier B for overclocking 5900x, Tier C for overclocking 5800X. Tier D for overclocking 5600X. Tier F for 4/6 core Cpus at stock. Tier E avoid.

(Also case airflow matter or if you are using Downcraft air cooler)

Spoiler

 

Gpu tier list. Rtx 3000 and RX 6000 not included since not so many reviews. Tier S for Water cooling. Tier A and B for overcloking. Tier C stock and Tier D avoid.

( You can overclock Tier C just fine, but it can get very loud, that is why it is not recommended for overclocking, same with tier D)

Spoiler

 

Psu tier List. Tier A for Rtx 3000, Vega and RX 6000. Tier B For anything else. Tier C cheap/IGPU. Tier D and E avoid.

(RTX 3000/ RX 6000 Might run just fine with higher wattage tier B unit, Rtx 3070 runs fine with tier B units)

Spoiler

 

Cpu cooler tier list. Tier 1&2 for power hungry Cpus with Overclock. Tier 3&4 for overclocking Ryzen 3,5,7 or lower power Intel Cpus. Tier 5 for overclocking low end Cpus or 4/6 core Ryzen. Tier 6&7 for stock. Tier 8&9 Ryzen stock cooler performance. Do not waste your money!

Spoiler

 

Storage tier List. Tier A for Moving files/  OS. Tier B for OS/Games. Tier C for games. Tier D budget Pcs. Tier E if on sale not the worst but not good.

(With a grain of salt, I use tier C for OS myself)

What speed do these show?

If it's anywhere between 1000 - 1200 or anywhere from 2133 - 2400 Mhz, it's indeed not running at the same speed.

 

It's probably a case of these RAM sets not having the same XMP profile, meaning you either need to dial in the speeds yourself or return the RGB set and get the same LPX set once again.

Try setting an XMP profile then manually changing the DRAM voltage to 1.45v, if that works try 1.4v. 1.35v is the default XMP voltage.

Try running user benchmark should tell you under the memory catagory, memory often shows up as half

Userbenchmark is utter trash.

dont mix ram sticks, even if first timings are equal ,secondary or tetriary timings are never the same,   ul get stability problems wether its in high or low profile problems shown

Thank you all for the replies! I took out the RGB memory and ran only the LPX ram, turned on XMP and forced the LPX ram to run at 3200MHz, and it's working! Task Manager says my RAM is running at 3200MHz now. So all that's left to do is return the RGB RAM and swap it to LPX.

 

Thanks again for all the advice!

As a resolution to this post (I know it's a late one), I did get more LPX RAM and now I am having no issues regarding RAM.

Thanks for the help and advice!
