Can you lower the frequency on RAM?

My computer runs slow - lower FPS than it should be. and the fun part is when I decrease the quality from ultra to high or even to medium nothing really changes. I ran Afterburner and AIDA and it showed that only about 3 gb is in use while hardware mem is over the roof. around 9GB! I turned hardware memory off in Windows preferences and nothing changes. Then I read the manual and realized that my mobo does not support ddr 2133 only in OC mode. I assume that this is the problem.

RAM G. Skill ddr3 2133 2x 4G
motherboard (MSI 970 gaming)
-------------------------------------------
I was wondering if I could just lower the Frequency down in BIOS or i have to get a new RAM?

i have fx-8350
but i don't think it;s the bottleneck because the overall CPU load during gaming is aroung 40%
and on most forums it says that fx-8350 is enough

I believe that the problem is with ram due to it's poor usage by the system. and hardware mem as i said is 9gb even when i turn it off in windows setting
 


That is alright and bad directions. In the task manager click on the performance tab at the top. and the on the left there should be a mem slot click on that and post a picture. Should look like this

Your RAM looks fine from that nothing is using up too much RAM or anything. Do one more thing real quick to check the timings and speed. Download CPU-Z and post a pic of the Memory tab.

yes the memory is not in full use. I think it's because some of it goes to virtual memory. because as I sayed the afterburner shows that it's 9gb use of virtual mem

 


Windows doesn't quite use RAM the way you think it does. I'll explain real quick

In use: Used by programs/drivers Can't be changed
Available: Physical RAM ready for immediate use
Committed: Where things get weird and where I believe afterburner pulled its numbers. Before the slash is total addressed/requested but not necessarily used by anything so it may not actually take any RAM/pagefile space. After the slash is physical + pagefile space totals.
Paged/nonpaged: Kernel/driver space
Cached: pre/superfetch

In your case everything points to it having plenty of RAM space available and your issue being caused by something else.

Thank you very much for your help! what do you think causes the fps drop? could it be PSU? because someone said that 650w is not enough for some reason...
 


That isn't impossible the 390 and the 8350 are both large power hungry components. The minimum recommended for both of those beasts is usually around 750W a good quality 650W might stand a decent chance of working though.

Does your FPS problem exist on all games or certain games? and Have you watched the 12V rail while playing a game?

EDIT: your CPU-Z pic finally loaded and it shows the RAM at 1600MHz (default) so RAM is good to go there.

yes. the same with all the games.
Now I am a little worried about my PSU. on pc part picker and on other websites it says that 500w will be enough... I don't know how to check it though.
This may be the problem. because when I turn on OC mode in MSI gaming app my PC seem to run even slower than without it...
 
Alright first reset the CMOS/BIOS Then download HWmonitor. On it look for the 12V rail should be towards the top and fire up a benchmark while watching it. It should stay right at 12V if it starts to go up or down depending on how much it'll be the PSU a multimeter would be more accurate if you can do that htough

I just turned on the game and it went up to 13.2V

So PSU is the problem?
 


Even if your PSU isn't causing the slow down that is a bad PSU. The absolute MAX for ATX spec 12V is 12.6V. 13.2V is way way too high. You might can check with a multimeter just to verify but I would definitely start looking for a new PSU.

Hi again. so... I changed my PSU from 600w to 750w (Corsair CX750M) and the voltage is again above 13v! I don't think is's PSU problem
 


That is really weird. can you test that with a multi meter just to be safe?
