AMD A10-7860k underperforming

[Filipe Gorges Reuwsaat]

Hello, I just bought the following set-up:

APU: AMD A10 - 7860k
RAM: Corsair Vengenace 8Gb (4GBx2) DDR3 2400MHz
MB: F2A68HM-HD2
PSU: EVGA 500W 80 plus white
2x Samsung 160GB HD (had them hanging around for some time)

And I've installed a few games, such as GTA V.
I bought this build mainly because of these gameplay videos:

This is the first APU build I've ever built, and from what I studied, APU's gaming performance is heavily dependent on the memory installed;

That said, I'm having trouble getting half the FPS displayed on the videos, at much lower resolutions (1360x768, 1270x720), with the lowest settings, the game's average FPS is constantly around 25fps, maximum of 30fps, so my guess is that the RAM frequency is wrong.

I've checked around and people said that I'd need to enable the X.M.P. on the UEFI, and doing so made it display the correct memory frequency there (2400MHz instead of 1333MHz), but on Windows 10 Task Manager, under Memory, it still displays 1333MHz. I thought I could simply ignore that information, but the performance I've been having suggests me that the speed might still be wrong. Here are some CPU-Z screens:

Any ideas?

Thanks in advance!

I'm so freaking stupid. I've been beating my head about this the whole day long. There was a setting on GTA V, Vsync, which was set to "Half". Disabling it made it run on average of 55fps, the lowest going to 25fps. I won't delete the thread, just in case someone falls for the same trap as I did.

Ok, but activate the XMP and check the profile. Some RAMs comes with more than one, so let's say: #1: 1600MHz (aparentely what you are using), #2: 2400MHz. Check this out

Yea i had a similar issue on the Resident Evil Remaster. Some in-game setting had a 60 fps, 30 fps, then "variable" frame cap. Trying to force 60fps at 1080p was getting me 20 fps. Variable let it fluctuate between 42-45 and ran waaaay better.
