Not sure how much it will add, but this also goes for your 4090, but you need to have ECC enabled for hwbot, but not for UL 3dmark website hall of fame. As of yet I believe.
And also remember...Certain driver changes or reset you will need to re enable that tweak.
If you can manage 27k and up then you are doing well with ECC enabled. 29k and up requires cards running 3200 to 3300+ on core
