Dual-channel RAM mode

[Vityu_sha]

1) Greetings, I had 6 GB (4 GB + 2 GB) of RAM in my laptop, I installed 16 GB (8x2, DDR3L, 1600, 1.35V)
Looking at CPU-Z, RAM is running in single channel, why? Is dual-channel mode not supported?

2) And a question about performance. For example, in the game World Of Tanks, FPS is 50-70 after loading the battle, but during active melee it becomes 15-20. Windows 10 has been reset to the "clean" state, the drivers for the video card are the latest, the discrete video card is working, but FPS is still not comfortable. The game settings and settings in Radeon Software are naturally minimal. Can't such hardware pull such an easy game? Maybe it's because of the single-channel RAM mode? The game support said that the FPS matches my laptop, but it seems to me it is capable of more 🙂

Hi:

The reason for that is because according to chapter 1, bottom of page 2 of the service manual, the notebooks that come with DDR3L-1600 memory only run the memory in single channel mode, no matter if you have two memory bars of the same capacity or not.

That was very common on AMD notebooks back in the day.

Thank you, what do you think about performance?

You're very welcome.

Your only benefit was adding the extra 10 GB of memory, which should have made a decent improvement.

Have you replaced the 500 GB 2.5" mechanical hard drive with a better performing 2.5" solid state drive?

If not, that will really pep things up.

According to your recommendations from this topic: Solved: Add SSD HP 17-010ur - HP Support Community - 8955073 I bought and installed a Samsung SSD 870 QUO 2TB SSD and updated the Wi-Fi Card according to your recommendation. To be honest, I didn't notice the performance in games, although I understand that an SSD can't give much difference in games, but I thought it would be better, only fast Windows loading and surfing the Internet became more comfortable

Yes, a SSD wouldn't help much with gaming, but as you indicated it increases general operating system performance. 

Adding more memory only helps with gaming if the additional memory allowed the PC to allocate more system memory to support the graphics. 

The graphics adapter is the main device that determines gaming performance, and there isn't anything you can do to improve that.
