Hi so I have 3200mhz ram and It says that the ram speed is 2133mhz. How do I change it to its advertised speed? Can this harm my pc? Cause it not to boot? I would appreciate it if you could walk me through the process

Motherboard: Gigabyte Aorus Gaming 7
Corsair 16GB 3200MHZ White LED

Being a new to this and your ram is new as well, yes you should. It will teach if the ram is good even at low speeds or needs to be returned. I have gotten bad new ram on more then one occasion. Anyways once you know it works when you "over clock" it and test it you know a settings is right, wrong or the speed is too fast for the CPU's memory controller or the ram itself should you overclock past 3200mhz ( you can do that ;) the 3200mhz is just the guaranteed speed the ram will operate at). As stated hitting 3200mhz on an Intel 8th/9th Gen CPU should be zero problem. If you can hit a CMD rate of T1 that is ideal for system responsiveness, assuming it is stable. So short story long memtest86 will is a great tool to ensure your OC's ram is running properly.

the easiest way is to go to your bios/uefi at boot and set the XMP profile to the rated speed. While this is technically overclocking your CPU's memory controller, at DDR4 3200mhz you shouldn't worry to much as long as your CPU temps are good (ie <80C) you should be fine. You can also manually set your timings in bios as well. They should be on the ram sticks if you don't know what they are.

Don't I have to change the Voltage and stuff? And what are timings?

this?

If you set the timings manually you may need to tinker with voltage, yes. XMP just does it for you. Here's some links on ram timings...

So what about the other question? Do I have to change the voltage? Could u tell me what to do since I told you my timings?

So you need your timings set at CL 16-18-18-36 CMD T2 with a voltage of 1.35V. If that boots properly you can increase you system responsiveness by dropping the CMD rate to T1. I usually get away with this on high quality ram but it is not a given and may not be stable. It is worth it if it is stable though IMHO. Use Memtest86 to test your ram stability (regardless of your clocks, CL or CMD). It needs to pass with no errors.

Do I do the test after or before?

I don't really see what you're trying to tell me to do in these settings

Where is the T1 setting? Is it located in the pics I sent you? and all I have to do is turn on the XMP then boot?

The CMD rate is with the CL timings under either realtime memory timing or memory timing mode...Bios their features are different between vendors, motherboards and models. So i am guessing a lil about where things are. But yes set XMP first and test it. Which i missed was on this one too with the timings I mentioned. If stable then trying a T1 CMD (may just listed as a T) to increase responsiveness (adds some speed to).

Alright well it booted with 3200mhz and I don't really want to do anything manually because I know, knowing me I will do something wrong and break something xD, but 3200mhz is a lot don't you think? Anyway thank you so much for the help, I really do appericate it :D

No problem...honestly i'd rather have T1 at 3000 mhz the 3200mhz at T2...You shouldn't break anything. In all likelihood worst case is it doesn't boot is all and defaults to slower settings until you can get back to bios and re-tune. But honestly it is your call. I am here if you need me.

I mean if there's an incredibly big difference then I'll do it, but if there's just a little bit then I'll pass.

It cuts the signalling speed in half running T1 so the boost is sizable IMO though not everyone agrees. You would have to increase the Mhz of your ram to get the same speed/bandwidth as a T1 with a T2 setting. So basically a slower clocked kit at T1 *can* be faster then a faster kit at T2...check this out.
