Do I enable xmp profile or dram frequency?

I bought 3200mhz Ram and just want to know what’s the best thing to do for setting my Ram speed at 3200mhz over the default speed 2133mhz. I’ve heard about enable xmp profile but not very familiar with that, I usually just adjust the dram frequency to the Ram speed. Any suggestions?

That's a pretty decent cooler from what I've read. I think that more airflow in the case could give you a few degrees. Also, I don't know how you're setup, but I'd setup my radiator to push/pull fresh air. I see a lot of setups pushing exhaust air over the radiator.

I like "positive pressure" setups to reduce dust. I have 2 front, 2 top, and 1 side intake with no exhaust fans. I get dust on my intake filters, but very little dust settles in the case itself.

More than anything I support trying different setups and measuring your temps to see what works best for you (be sure to measure the delta -> coretemp/ambient). Good Luck!

XMP will set your frequencies, voltage, and timings to the manufacturer's spec for that RAM kit. Without enabling XMP, you would have to manually set those things. I have seen it where XMP doesn't work but manually setting does, though I couldn't tell you why. In general, XMP is the way to go.

Simply adjusting the frequency may or may not work depending on whether it can run those frequencies with default timings and voltage.

I enabled the XMP Profile and the it said it automatically makes adjustments according to the RAM specifications. I noticed my cpu temps raised allot more after running a game application to the maximum temp of 81 degrees celcius. Initially before enabling XMP Profile the maximum temp under load was 67. In both cases I had intel turbo boost enabled which says its target speed is 4.7ghz since I have the intel I7 8700k. So I'm wondering the enabled XMP profile must be generating extra heat in the case causings CPU temps to rise. I'm not even sure whether I should keep as is with maximum temp being 81 degrees or so under stress because I'm not 100% confident with it. Is there some sort of other adjustment I should make to help reduce the temp? Also I'm not too familiar with overclocking, but my main goal is to try to reduce overall temperature and keep my RAM specs as is.

Your RAM is directly connected to your CPU, so as you raise voltage and speed on the RAM, you are affecting the CPUs memory controller as well.

If 81C is your high under stress testing I wouldn't worry about it. Even for gaming, that's probably ok (I prefer sub 80). You might look at a better cooler if you want to keep your XMP enabled and get those temps down a little.

That said, I can't really tell the difference on my RAM (2133 vs 1600) and so I just run it at the lower setting. But depending on what you're doing, you may see a noticeable difference.

Recently I have been thinking about getting a new case but not cooler. My case is very enclosed meaning it only has an air intake fan in the front of the case and an exhaust at the back very basic. I’m not sure whether having additional fans in the case would make a considerable difference but I’ve heard temps are so much better when you have your case open but of course allot of people don’t do that due to dust and stuff. So the replacement of the case for a better ventilated one is more of a sounds solution to me. For the cooler I’m already using Corsair h55 hydro series cpu water cooler which is approximately 3 years old. I’m not really sure if it would be wise to replace this water cooler for a new one of similar type. What are your thoughts?

Your right about using water cooler radiator with the fan as air intake this way it could keep the radiator cool. But the reason why I didn’t do it is due to the placement of my computer and lack of space. The back of my computer is facing the wall and there is no filter to prevent dust particles from spreading inside of the case the way my front 140 mm fan does. So I think if I made my back a air intake fan dust particles may build up faster. logically thinking I just assume it’s best to have at least one exhaust fan to remove hot air from the case as cool air gets, simply like an air conditioner method. I will purchase a better ventilated case so I can have more intake fans to bring in cooler air. My ideal ventilation setup would be to have 3 exhaust fans in the back 2 top and one back as that area is a bit crowded and to allow for more hot air removal. Then two front fans as they are exposed to the open as intake, more than likely there will be filters there.
