Stutter and frametime issues

[Zelenia]

Hey,

 

I've got weird stutter in some games since GPU upgrade (check sign). First I thought it's the drivers but there seems to be more into it. My frametime jumps around 10ms-70ms all the time and I don't really know where to start the troubleshoot with. (I'm editing the post and accidentally posted it before finished)

mixed ram = mixed frametimes is my guess

I did buy the memory in a bundle and I did check it and they look identical to me. Memory speed shows 1600mhz on Gpu-Z and Hwinfo but it probably means single card speed. On BIOS it says memory speed is 3200Mhz (dual). I haven't been able to do any memory test tho, some software I did try to use crashed.

 

My first guess was ofc GPU drivers but updating or downgrading and checking power cables didn't help much. I haven't tried to change the cables connected to monitors so I guess that's the next thing.

 

Other thing I've been considering is that I got 2 monitors with different hz connected to GPU. Other one is cheap TN panel 144hz (https://www.acer.com/ac/en/HK/content/model/UM.FX1CF.P01) and other is 2nd hand HP IPS panel 60hz (good quality, it was probably in office use for max 2years).

Not sure how that makes sense. If you mix sticks with different frequencies and timings, they'll simply run at the slowest common speed and highest common timing. The memory controller can't run at different speeds at once.

CPU-Z shows physical clock speed, which is 1600 MHz for 3200 MT/s RAM. DDR (double data rate) can do two operations per clock cycle which is why it is marketed as having an "effective" clock speed of 3200 MHz, even though technically the correct term would be 3200 million transactions per second (MT/s), not 3200 MHz.

I actually did read that wrong  and thought u have mixed ram my bad.

 

But that is still interesting that the software crashed, what was it?And you should probably try memtest 64 just to make sure.

 

you could also try running the ram without XMP at default speeds and see if its more stable. Some motherboards have issues with XMP.

My PC just straight up did freeze and I had to turn off PSU from back to do a hard reset. 

 

I'll try to run the memory test again and if that doesn't show anything I'll try other XMP profiles or turn it off.

yeah, thats a good idea. and which memory test?

I used today MemTest64 from TechPowerUp. Got no errors this time. 

 

Something did happen and the stutter disappeared randomly... This is quite weird.  Now frametimes are fine again and no stutter. I'm sure it will be back at some point and I need to pay attention what I'm doing when it occurs.
