This is my third GPU from Sapphire (570 Pulse, 6700XT Nitro+), but this had to be dealt with. At the price of losing the warranty. Although how much would it have helped if I sent it in every few months to have the same TIM applied to it? Because the Pulse never reached the temp limit (115°C ?) required for replace/refund.
the honeywell PCM or kryosheet are permanent fixes..
That sounds good. What I read about it is all positive. Some reported getting better after several months.
My 7900XT Pulse is stable at 1030mV pretty much anywhere. I've tried 1020 and 1025 but it crashed in less demanding games like warframe. It was stable in cyberpunk and 3dmark though. I guess maybe your sample needs more juice?
I don't know. I'm currently running at 1040mV. One crash in 36 in-game hours seems pretty random though. Other people have also complained about Cyberpunk crashing with AMD GPUs.
what kind of radiator and case u have ? 42c water temp is the reason for this kind of temperatures my guess.
I'm using 1 360 radiator just for the card, cpu is not part of the loop yet. (planning on adding another 360 rad. later on for the cpu)
Yeah, should've stayed on air I guess. The total amount spent on the loop and to get same performance its just sad, could have gone for the 4090 straight away but that's what you get for the first time building. Will give it one more reassembly tomorrow tho and wrap it up.
Above 40c water temp u start losing any gains in water cooling.
I've got just 3 fans on it as intake and the radiator is 30mm. The space is unfortunately limited to 3 extra fans.
I tried FF14 benchmark but it wouldn't crash even with 1000mV undervolt. So I guess every card is unique when it comes to stability and overclocking.
