Really bad frame drops

[Dazza111]

Hi I have a bad frame drop problem I cant solve 

 

my pc 

5900x 

7900xtx 

32gig ram 

windows 11

 

its not over heating,  will be at 200fps then drop to 20-30fps for a few seconds and it happens every minute or so

the board power drops as well 

 

any help would be most appreciated

A little more information would be very helpful if possible.  Also, what PSU are you using?

What games were you playing when the drops happened?

 

How could you tell that it was not because of overheating? Did you have something to monitor the temps? If yes, what was it, and what were the temps?

 

Provided that what you gave was all true and correct, I think you could check the power/voltage of your CPU and GPU to see if it's stable. You can use MSI Afterburner to monitor this while gaming. It is possible that your PSU is defective and causing this problem.

 

I'm saying this because I used to have this kind of problem but a little bit more serious. My whole system would stutter heavily and eventually shut down during high loads. I didn't know the reason until I fired up FurMark benchmark and noticed that my GPU voltage wasn't stable. It jumped back and forth between high and low wattage before shut down completely during the benchmark. I then opened up my PC and re-seated the PSU cables, hoping that they were all just loose, and it's not that my trusty SF750 was defective. And yes, it was that the cables were loose.

I have a 850 watt power supply,  I use adrenaline software on screen and the fps drops hard and so dose the total board power.  happens when playing most games,  pubg, hell let loose

Brand of PSU? That can make a difference.

I am also using the Adrenaline software and it can be very "choosy" in how it works.  You just have to play with the settings to get it right.  For info, I play only one game, World of Warcraft.  Before I got an idea on how to "tweak" the settings I was lucky to get only 50-60 FPS, but now I am getting much better at 450 plus sometimes even hitting 600 plus.  I included two pics of what I am getting, I really did good back in December as you can tell.

 

Good Luck and Take Care.

Difficult to say for sure that the PSU is the problem, but the 5900x and 7900XTX are some extremely power-hungry parts. Your PSU may be rated for a total draw of up to 850w, but the individual rails also have limits.

Your 24-pin motherboard connector is almost always on its own dedicated rail since it supplies power to the board itself and all of it's on-board devices. It also powers the CPU (in your case up to 150w ish). It also supplies up to 75w of power to each of the PCIe slots.

However, your supplemental CPU connectors and PCIe Power may be shared, and those two items may be exceeding the rail limits. The 7900XTX alone can draw almost 400w depending on make and model.

 

You may want to set a modest power limit in Adrenalin and see if that helps. You don't need to cap the frame rate, but if you work with a smaller power envelope, you will probably get a lower max FPS value along with higher 1% and 0.1% lows.
