DRAM Frequency is lower than it should be. No advanced tab in BIOS

Last night I tried adding a 2gb ram card on my Aspire F15 - F5 572G- 50AX. It fitted so I assumed its the right card. Launched a game only to notice I was getting half the fps I usually get, and even lower. All good, I removed the card hoping it would fix the problem but it didn't. My games still run with less fps than they are supposed to run. I read many articles on the internet saying I can change the speed in the BIOS, but my bios doesn't have an Advanced tab where I can change it. Some sites said press A and Advanced will appear, others said to press FN+Tab 3 times, neither worked.
My original card is Kingston 8GB DDR3 L
Info on CPU-Z:
NB Frequency :2594 MHz
DRAM Frequency : 798 MHz
CAS# Latency 11.0 clocks
RAS# to CAS# Delay 11 clocks
RAS# Precharge 11 clocks
Cycle Time 28 clocks
Row Refresh Cycle Time 208 clocks
Command Rate 1T
What can I do?
I also removed the card and put it in again

Have you tried to reset the internal battery?

Issue fixed after the reset

In fact, the speed of your ram memory is 1600 mhz, because you multiply 800x2! Also, this kind of change is a risky procedure and can turn your notebook into brick!

egydiocoelho I don't really know but still why did all my games lose fps. it only happened after the ram change. does this mean my laptop is fried?

Commodore_1995#

Not! Can you tell the exact model of 2gb ram?

Dark4Soul

Samsung 2gb ddr3 1066MHz

You should have another ddr3L and not a ddr3! In my opinion, the ideal is to acquire another ram memory with features similar to the original!

Dark4Soul

And will that fix the fps issue? Or the dram frequency?

Commodore_1995#

The dual channel can improve fps. However, I'm not sure what's causing the FPS crash! Have you tried putting the notebook in high performance in the power options and the video card?

Dark4Soul

Yes every setting is focused on high performance. I know this issue is related to the ram. Would it work if i borrow a ram, put it in, start the pc so it changes the frequency, then I remove it later?

I would like to know the partnumber of memory you have purchased. About your question, your processor limits the speed of ddr3L memory to 1600mhz, see: https://ark.intel.com/content/www/us/en/ark/products/88193/intel-core-i5-6200u-processor-3m-cache-up-to-2-80-ghz.html

What's a partnumber

Dark4Soul

I didn't buy it i i had it around the house

Ideally, you should buy another memory identical or similar to the original, so that the dual channel is activated! Now I would like to know how much of fps you were getting before and how much do you get now?

Fortnite save the world: before 60-80/ after 14-20
Rainbow six siege: before 50-70/ after 8
Everything on low and performance settings in nvidia control panel
Would a factory reset change my dram frequency back to default? Maybe a Windows 8.1 from 10

What is the speed of ram memory shown in the task manager? Have you tried reinstalling video card drivers? Have you checked that the dual channel is enabled with cpu-z?
