X99 platform, memory question. Help is appreciated.

Hello,

 

I hope this is the right place to ask this very specific question, but here goes nothing :)

 

I have an MSI x99 Krait edition mobo with an 5820k and currently 4x4 Kingston Hyper X 2400mhz memory modules. 

I want to upgrade my ram because I do light video and photo work, and i still have 4 more slots available. Now my question is, what will happen if I  have 4 x 2400mhz HyperX modules and add 4 x 3000mhz HyperX Savage modules. Will it straight up not work? Will my 3000mhz ram run at 2400mhz? 

 

Any information regarding this would be greatly appreciated. And i'm sorry if a similar post already exists or if this is the wrong place to ask, it is my first time on this forum and couldn't really find anything useful yet. 

 

Thanks in advance,

YellowEdits.

It should work just fine :)

If you want to check at what speed your ram runs right now, download CPU-Z and check it.

The ram speed might be weird at first sight but you have to double it.

If you want my attention, quote meh! D: or just stick an @samcool55 in your post :3

This is what it says right now, but this is with the 2400mhz memory running in quad channel. I should just try it with the 3000mhz sticks as well? They would also be running in quad channel mode. Thankyou for the fast reply btw :) zQ4QBiM.png

Simple answer: Yes, the RAM will limited to the speed of the slowest RAM in the system.

 

Detailed answer:

All the RAM will run at 2133Mhz by default. You can use the XMP profiles to bring that up to what the RAM is rated for but all the RAM will run at the same frequency/timings.

 

You have two options:

Run all 8 sticks at 2400Mhz or

try to manually overclock your 2400Mhz sticks to what you are able to get stable. I don't think they'll get 3000Mhz but you should be able to get 2666 and might be able to manage 2800 if it's a good lot. I don't think you'll be able to get to 3000Mhz on the current RAM.

Having issues with a Corsair AIO? Possible fix here:

Spoiler

Are you getting weird fan behavior, speed fluctuations, and/or other issues with Link?

Are you running AIDA64, HWinfo, CAM, or HWmonitor? (ASUS suite & other monitoring software often have the same issue.)

Corsair Link has problems with some monitoring software so you may have to change some settings to get them to work smoothly.

-For AIDA64: First make sure you have the newest update installed, then, go to Preferences>Stability and make sure the "Corsair Link sensor support" box is checked and make sure the "Asetek LC sensor support" box is UNchecked.

-For HWinfo: manually disable all monitoring of the AIO sensors/components.

-For others: Disable any monitoring of Corsair AIO sensors.

That should fix the fan issue for some Corsair AIOs (H80i GT/v2, H110i GTX/H115i, H100i GTX and others made by Asetek). The problem is bad coding in Link that fights for AIO control with other programs. You can test if this worked by setting the fan speed in Link to 100%, if it doesn't fluctuate you are set and can change the curve to whatever. If that doesn't work or you're still having other issues then you probably still have a monitoring software interfering with the AIO/Link communications, find what it is and disable it.

Different platform, but currently have 2x3600 and 2x3200 speed dimms on one board.  The 3200 stuff won't clock up to it's rated 3200 on this platform (x399) so all 4 sticks are dragged down to 2133.

Still better than dual channel (just 2 dimms)  though for what I need though.
