3090 Strix voltage instability

[Doctor]

So I have been playing around with my 3090 strix this morning, and I notice that in benchmarks it runs a stable 2075-2100Mhz and it finishes normally. However, if I load up Red Dead Redemption 2, it crashes after 5-10s and if I look in GPU-Z it was boosting to 2190Mhz and gpu-z says that voltage reliability was performance limiting before the crash.

What is this behaviour? Can I prevent the gpu from boosting any higher than 2100Mhz manually while maintaining the overclock? Or do I have to reduce the offset?

reduce the offset retest you should test in multiple games to find the right OC

Will need to reduce core offset and test in game , i found that Timespy overclock settings are not game stable at all on mine ... on the strix 3090 can run +146core and +650memory on timpespy and pass but if trying to run that in games the core will boost way over 2100mhz and crash . i have found it game stable at +100core / +400memory and this results in the core boosting no higher that 2115mhz which so far seems stable in most games i have tried

wow, thats a great overclock! I was thinking shunt mods would be needed for over 2100Mhz!

Update

I found that +133/+250 was stable in Red Dead 2 after testing. Now it boosts to 2100Mhz during gameplay but doesn't crash. Nice to play Red Dead on the highest possible preset and see 60fps locked
