Hey guys, so i just got some 32gb 3600 ram, my cpu only allows me to use 3200 but xmp it forceing me on 3600 when i turn auto on. So this lets me in but just crashes my games when i try to play, can i just switch the mulit speed to 3200 or do i have do a lot more? really new to this kind of stuff.

Your CPU really has nothing to do with what memory speed is supported on a given motherboard, with a few exceptions like some of the earlier Intel platforms that had memory speed ceilings based on what CPU model was installed, but those limits are not the same as what you see listed in the CPU specs for the NATIVELY supported speed for that CPU. The natively supported speed is NOT the actual limiting factor for a given motherboard chipset, instead, it is the chipset itself which generally determines that limit and is found by looking at the MOTHERBOARD specs, not the CPU specs.
What are your FULL hardware specifications including CPU model, motherboard model and exact memory kit model?

No, I think his problem is that he's using "Auto" and NOT using XMP. But if that isn't the case, then obviously you're right and entering manual values might be the way to go. You also want to make sure you are running the latest stable motherboard BIOS version because a lot of BIOS revisions exist for the purpose of increasing DRAM compatibility on a given motherboard.

Set XMP, then manually switch the speed to 3200MHz isn't an issue.
But that's assuming that the speed is the issue and not the XMP timings as set, which won't change with a speed change.
What would probably be more effective is a voltage change. Set the XMP and then if using AMD then bump the SoC voltage up slightly and dram voltage upto @ 1.38v. If using Intel, bump VCCIO and/or VCCSA upto 1.15v and dram voltage to 1.38v.
That's going to give the memory controller and ram a little more juice to work with, because XMP is a generic setting and some cpus/ram can have small stability issues with those generic settings.
In the past, general concensus was that overclocking actually could help ram stability, because the Auto settings would automatically apply higher memory controller voltages to compensate.

So, that board only supports up to 3200mhz speeds when using 11th Gen i5, i7 or i9 processors based on the motherboard specifications. I would recommend that you manually set the memory speed to 3200mhz, DRAM voltage at 1.35v and leave everything else on Auto, as a first try. If that doesn't work and if you are not familiar or comfortable with manually configuring the timings and voltage then I'd suggest perhaps returning the memory kit and buying a kit with an XMP profile speed of 3200mhz.

Myself, I'd try it with XMP off, memory frequency set to 3200mhz, DRAM voltage set to 1.35v and the rest of the memory settings on Auto. See if that works. If not, you may need to set XMP to enabled and then drop the frequency to 3200mhz as suggested above. If neither of those work, then the problem might not be the settings but simply the memory kit not being compatible with your specific motherboard. Just because it's the right TYPE of memory and the speed is supported doesn't mean all modules will work with all boards, because they won't.
I just did the Xmp off and set it to 3200 and change the volt, and just hopped on mw2 and ran the bench mark, it worked! last time it would just crash during it but this time it completed. So now do i need to run any other apps to see if im getting any errors or should i be good to go?

I would recommend testing the configuration with Memtest86. It is going to take a while to run four full passes so you might want to run it while you watch a movie or overnight while sleeping. Unless you like watching X's turn circles. LOL.
Go to the Passmark software website and download the USB Memtest86 free version. You can do the optical disk version too if for some reason you cannot use a bootable USB flash drive.
Create bootable media using the downloaded Memtest86. Once you have done that, go into your BIOS and configure the system to boot to the USB drive that contains the Memtest86 USB media or the optical drive if using that option.
You CAN use Memtest86+, as they've recently updated the program after MANY years of no updates, but for the purpose of this guide I recommend using the Passmark version as this is a tried and true utility while I've not had the opportunity to investigate the reliability of the latest 86+ release as compared to Memtest86. Possibly, consider using Memtest86+ as simply a secondary test to Memtest86, much as Windows memory diagnostic utility and Prime95 Blend or custom modes can be used for a second opinion utility.
Create a bootable USB Flash drive:
1. Download the Windows MemTest86 USB image.
2. Right click on the downloaded file and select the "Extract to Here" option. This places the USB image and imaging tool into the current folder.
3. Run the included imageUSB tool, it should already have the image file selected and you just need to choose which connected USB drive to turn into a bootable drive. Note that this will erase all data on the drive.
No memory should ever fail to pass Memtest86 when it is at the default configuration that the system sets it at when you start out or do a clear CMOS by removing the CMOS battery for five minutes.
Best method for testing memory is to first run four passes of Memtest86, all 11 tests, WITH the memory at the default configuration. This should be done BEFORE setting the memory to the XMP profile settings. The paid version has 13 tests but the free version only has tests 1-10 and test 13. So run full passes of all 11 tests. Be sure to download the latest version of Memtest86. Memtest86+ has not been updated in MANY years. It is NO-WISE as good as regular Memtest86 from Passmark software.
If there are ANY errors, at all, then the memory configuration is not stable. Bumping the DRAM voltage up slightly may resolve that OR you may need to make adjustments to the primary timings. There are very few secondary or tertiary timings that should be altered. I can tell you about those if you are trying to tighten your memory timings.
If you cannot pass Memtest86 with the memory at the XMP configuration settings then I would recommend restoring the memory to the default JEDEC SPD of 1333/2133mhz (Depending on your platform and memory type) with everything left on the auto/default configuration and running Memtest86 over again. If it completes the four full passes without error you can try again with the XMP settings but first try bumping the DRAM voltage up once again by whatever small increment the motherboard will allow you to increase it by. If it passes, great, move on to the Prime95 testing.
If it still fails, try once again bumping the voltage if you are still within the maximum allowable voltage for your memory type and test again. If it still fails, you are likely going to need more advanced help with configuring your primary timings and should return the memory to the default configuration until you can sort it out.
If the memory will not pass Memtest86 for four passes when it IS at the stock default non-XMP configuration, even after a minor bump in voltage, then there is likely something physically wrong with one or more of the memory modules and I'd recommend running Memtest on each individual module, separately, to determine which module is causing the issue. If you find a single module that is faulty you should contact the seller or the memory manufacturer and have them replace the memory as a SET. Memory comes matched for a reason as I made clear earlier and if you let them replace only one module rather than the entire set you are back to using unmatched memory which is an open door for problems with incompatible memory.
Be aware that you SHOULD run Memtest86 to test the memory at the default, non-XMP, non-custom profile settings BEFORE ever making any changes to the memory configuration so that you will know if the problem is a setting or is a physical problem with the memory.
