Strange crash behavior after upgrade from GTX 970 to RTX 3070

[Cyano]

Yesterday I upgraded my old GTX 970 to an RTX 3070, without changing anything on my old Haswell System (specs below). After playing a bit I crashed (full reboot) in some games, and my motherboard would say "power surge detected". To find the issue I disabled the warning, just to find out that my PC still crashes. After reading up online I concluded that its most likely a power supply issue caused by some heavy spikes on the new GPU, so I bought a new Seasonic 750W, which will arrive soon.

 

The strange thing is that I can reproduce a crash in Red Dead Redemption 2 where I crash with 50% CPU, 50%gpu usage when looking at the sky, while my frames are capped to 80, so the usage stays down. When I look straight I don't crash.

 

Is there anything that might be worth trying, if the power supply upgrade doesn't fix the issue? Before sending back the new hardware, or things I haven't considered? Any help would be appreciated.

 

My specs:

 

Windows 10 x64, no oem, Desktop

Seasonic SSR-550RM

Asus Maximus Vii Ranger

Vengeance LP™ Memory — 16GB 1600MHz CL9 DDR3

Intel® Core™ i7-4790K, 4.5 GHz (I know I should upgrade, but thats not the problem here)

RTX 3070 Asus dual OC

2 old SSDs and one HDD

your cpu is bottlenecking 

get an third gen ryzen

or an 8th gen intel at least

I know, but thats not the problem. I will do a cpu upgrade later. A bottleneck should not cause a crash. And its only rly a problem in cpu intensiv games, I am mostly happy with my fps.

Most likely the PSU, so just come back if it's not fixed with the new one. Pointless to speculate until then.

sure, will close it tomorrow if it is fixed or give an update here.

Yeah for sure get another power supply.

There are good recommendations here in tier list.

I had same problem on my asus board with current PSU.

The problem happened because of a GPU which required more power over 2x8pin connectors.

It doesn't mean that PSU is faulty it's just can't give enough power over 12 V rail for GPU.

So for sure get the one which can on 12 V rail.

Yeah it's likely power supply... probably your cpu is drawing quite a lot of power too? 

 

Just weird I'm running a 500w psu and no issues whatsoever with a 3070... 

 

Btw, things you can try:

 

Install studio drivers 

 

set power limit to 90

 

reduce core clock by 25-50

 

reduce memory clock (at least by 100)

fixed, was the psu
