Voted yes to OC GPU
.
Current GPU:
Sapphire Fury X (Ref PCB/AIO cooler, factory TIM/pads), ASIC Quality 64.4%.
Stock GPU: DPM 7 1050MHz @ 1.212V VID
24/7 GPU OC: DPM 7 1145MHz @ 1.268V VID
Note:- I'm stating actual VID commanded by GPU, due to LLC and other "effects" my VDDC is lower (what shown in SW monitoring).
Stock HBM: 500MHz @ 1.300V MVDD
24/7 HBM OC: 545MHz @ 1.325V MVDD
OC was tested using combo of MSI AB and i2c commands to gain HBM MVDD increase. 24/7 OC is set via custom bios mod by me
. I use a custom UEFI/GOP module in VBios courtesy of
Lordkag of Fernando's WIN-Raid Forum
. I require the custom UEFI/GOP module to allows "CSM Off" with modded VBios, so "pure UEFI" mode can be setup for Win 10 use (I could go legacy but wanted UEFI). I can not use "Secure boot" with my custom ROM/UEFI due to inability to update "signature", which is AOK by me
, "Fast boot" works though

GPU OC has been running since Mar 16, HBM a few months after that as a long term experiment of voltage increase effect on HBM. No issues in various games which are GPU heavy (ie Crysis 3, etc) for many hours. Over 3hrs each 3DM FS / Heaven / Valley / RealBench tested. Many hours of f@h done, my minimum run will be 12hrs and at times upto 48hrs continuous, not a single instant of "bad state" in f@h detected in my f@h runs

My 3DM FS stock vs OC
result, same driver/3DM UI version, driver defaults (ie no tess.tweak), no OS tweaks to improve bench result. HBM OC accounts for very little of the scaling gained from complete OC (IIRC max 1-2%). Plan to spend some time comparing FRAPS runs of games of stock vs OC, but not found the time, spent too much time OC'ing/tweaking rig so now plan to enjoy it
