Low Ram Speeds?

[iRainDrop]

Hey. A while back (months ago) I decided to upgrade my 8GB of ram to 16GB, upon receiving the ram and putting it in my PC, I noticed that my ram speed in my task manager was set at 1066MHz. I've tried enabling the XMP profile for the ram kit I purchased and I've even tried manually setting the voltage to 1.5V (the voltage rating of the kit I bought) and the timings to 18-22-22-42 and the speed in Task Manager stays the same (check attachments below). At this point I have manually overclocked my ram to 1800MHz and that is now what it displays as in Task Manager but I paid for a 3600MHz ram kit, not 1800MHz. I understand that a lot of people say that Task manager displays half your rams speed but before I upgraded my ram it definitely didn't show anything below 2000MHz and when I've checked any of my friends PCs or even family members, they all display above 2000MHz+ with cheaper ram kits. Even inside of Tools like NZXT Cam and CPU-Z, it still displays as 1800MHz. My PC even uses 35%+ Ram at IDLE with NO programs open and right after being freshly rebooted, that's definitely not normal.

 

I've spent a ton of time looking into this issue and have found nothing that helps other than overclocking the ram itself and at this point I don't want to push it any further. I am not looking to damage my PC and I've already overclocked it pretty high over the default frequency. All I can find is that the ram kit I purchased is not compatible with my motherboard/CPU combo but it still registers and works, obviously not exactly how it should.... Should I just get a new kit and make sure that it is fully compatible with all of my other parts or is there anything else that I could be missing?

Thanks in Advance to anyone that tries to help!

Ram is running dual chanel, it'll display at half its speed this is normal, 1800 displaying for 3600 dual chan is normal

Has nothing to do with how many channels you have, but you're on the right track.

 

It's due to that fact that DDR literally stands for double data rate, which means you get two transfers per clock cycle. 3600MHz RAM doesn't actually exist. It's 1800MHz with 3600 MT/s (mega-transfers per sec, 2x1800). Manufacturers just label it as 3600MHz because consumers are more familiar with the MHz terminology and it's effectively the same as if the RAM actually was 3600MHz with only one transfer per cycle.

15 years ago I probably would've remembered this

Probably for the best. Clockspeed, transfers, timings, channels, ranks, density... So much info to store for something so seemingly benign.

That makes no sense. My brothers PC runs in dual channel and displays 2666MHz, same with every other PC I've looked at... Also, Like I said, my pc at idle uses a lot of ram for no reason...
