Task Manager in Windows 10 displays wrong memory speed...

Hello! I have a Lenovo Y700 gaming laptop with 8GB of DDR3 RAM. (AMD-FX Edition). I had to create a new user account due to issues I had with my other one. Everything was okay until I looked at Task Manager and realized it displays my memory speed as 800 MHz instead of its actual speed of 1600 MHz! This started to occur ONLY when I made the new account! I was wondering if this is a bug in Windows 10, or if something managed to happen with my memory when I made the new account for whatever reason. If anyone could help, that would be amazing!
Thanks!
 
That memory speed is correct since ddr means double data rate. If it says 800 mhz then its really 1600mhz. I'm running 1600 mhz and task manager says 800mhz for mine too.
 
Odd, mine says 1600 MHz.

If you can manually set the frequency in BIOS to 800 then it's at 1600 MHz. If you aren't able to run CPU-Z then you might have other problems with your PC.

Why not just post the answer in case anyone else shows up looking for the solution

Because sharing's too much of a socialist concept! ;)

Joking aside, I am interested to find out what the problem was. Funnily enough, I recall Windows 10 Task Manager though my system had DDR2 memory at one point. Turns out one of my ram sticks was dying. RMA'd it and the new set doesn't show DDR2. Instead, it just doesn't show any memory information at all. lol
 
You don't need to post like 5 posts of the same thing but quoting each person differently in each one. You can just click on the +Quote button and then click on all the ones you want. Then insert all the quotes at once and ask the question.

Sorry. But do i have to ×2 the RAM speed in Speccy?
 
old post where everyone is confused , so here we go, ,, 1600 ram runs at 800 if not in dual channel mode,, , 1600mhz is marketing label,, it actually runs at 800,, so if you have 2 sticks running at 800 it can access each ram at the same time so in theory that would be 1600mhz,, so if you have 1 8gb ram stick installed it would show 800mhz,, also if you have 2 sticks that are not the same size , so i 4gb and 8gb it runs at 800 as it can only read from 1 stick at a time if not equal size,, so to explain ram labeling further , if you have 2 4gb sticks installed or 2 8gb it will auto run in dual channel mode and show 1600mhz,, they are soon changing the ram label to be in mt/s as it referred to the amount of date can push , instead of lying saying 1600mhz ram when its not its 800mhz and 2 at the same time just doubles the amount of data it can push , not the speed of the ram,, so really if in dual channel its 800mzh not 1600mhz , just a theoretical number , so really they should put on the ram 800mhz so people dont think they will get 1600 with 1 stick,, lol, marketing scam really

That's not how DDR works. DDR is able to transmit data through both the positive and negative peaks of the signal, hence it can deliver data twice per clock. Hence "double" data rate, because prior to that, SDR was able to only transmit one set of data per clock.

You can spin it like that, but technically the 1600mhz "marketing label" is the effective rate for which data is transferred at when compared to SDR.

single/dual/triple/quad channel memory is a totally different topic that is not related to the whole 800mhz clock speed is effectively running at 1600mhz for SDR.
 
DDR has always been that way when considering actual and effective frequency, in comparison with traditional SDRAM as per @Intel_man it can transfer data on the rise and fall of the clock cycle.

The operating frequency has nothing to do with channelization, if you have one stick at 800 MHz actual / 1600 MHz effective, it's still running at that clock speed with a single stick, two sitcks, three sticks, four sticks, etc.. The only difference in dual channel mode is that you have another 64-bit bus of throughput effectively doubling your transfer capacity over a single 64-bit bus while the sticks remain at the same frequency they were.
