Question Massive FPS drop on games

[Jay2hollow]

Found an old rig and decided to get a new GPU for it to relive some old games again.

I bought a AMD RX 6650-XT and cheap RAM for it a few months ago and things were smooth but this past month suddenly get really low FPS on games like League and WoW dropping to 25 fps and can't even run Diablo 4.

I ran a user benchmark and its not looking so good:

and cheap RAM for it

Why did you buy two individual sticks at different capacity? It is asking for problems.

Pop out the 4GB stick and look if things improve.

Also, your background CPU usage is high. So, what programs you have running at all times?

Run ubm like this.
Reboot.
Wait a few mins.
Run ubm with the browser closed.
Post a link to the results page.

Thanks, looks like i had a lot of programs on start up clogging up CPU Usage.

I ran UBM on a reboot: https://www.userbenchmark.com/UserRun/68479808

The 2x8GB RAM seems to be performing rather poorly and I don't have the option to XMP setting in my bios.

GPU not so great, guess I should OC?

I did attempt to add another 2x8GB RAM giving total of 32GB but the PC wouldn't boot past bios.

That run looks normal, for such an old PC.

What revision is your MoBo?

Since there are 6x revisions of Gigabyte GA-78LMT-USB3. E.g latest revision, rev 6.0, DDR3 RAM speeds are 1066 Mhz, 1333 Mhz and OC/XMP 1600 Mhz.
Do note that when your RAM doesn't support 1600 Mhz, there is no XMP option for you to choose from.

GPU not so great, guess I should OC?

That GPU isn't suited for such an old build.

GPU needs PCI-E 4.0 x8 to operate, while PCI-E x16 slot on your MoBo (if you have rev 6.0) is 2.0. And since GPU uses only x8 lanes, it is actually operating at PCI-E 2.0 x8.

It does work, since PCI-E revisions are backwards compatible, but you will loose performance. Performance drop isn't much though, 4% or so;

What the build is held back mostly, is due to the 12 years old FX-6300 CPU. That CPU, 12 years ago, was mid-tier. Now, it is FAR worse, compared to the current generation.

things were smooth but this past month suddenly get really low FPS

I think you have bloatware/malware or in general: software issue.

Easiest fix: format OS drive and make a clean Win installation again.
Since hardware wise, hardware is working as expected and there's nothing you can do, to improve things.

That run shows you have been up for almost a day.

Try running ubm like I wrote above.
