I appears HX processors may be affected.
Discord has a few interesting communities that I frequent. A unofficial Legion discord houses all kinds of nerds that look into things deeper than me and report back with findings to those who care.
One such chap got a hold of an Intel document, stating that the microcode updates fixed (IIRC) 3 out of the 4 issues with voltage spikes.
Said chap has actually bullied ASUS for months to update microcode and they have finally done so. A few other OEMS have already implemented the new code in BIOS revisions, Acer is one such OEM IIRC. Lenovo have yet to implement all the fixes....
Why am I here pointing this out?
Well, I am already on my second motherboard in my LP7i since my 14900HX dropped about 3-4k in Cinebench R23 and started needing more voltage for clocks that had been stable for a good while.
My second motherboard is now going a similar route. I had strange OS issues and short version is I tried OS repairs, failed, Clean install of 24H2, failed. Full Lenovo System Restore and my machine is a little less janky.
All this started with Remnant 2, constantly getting "out of video memory" errors and game crashes. I've tried all kinds of Nvidia drivers since the last stable driver is 561. I did see that Remnant 2 has issues in general. Only Silent Hill 2 will randomly do the same. Thing is, when you google this issue, all replies state you need the latest Intel code BIOS and this IS a 13/14th gen degradation sign.
For full clarity, I am a little more of an advanced user, I have lowered the LLC from 170 to 110 since Legion Optimisation stopped doing that itself. This lowers requested voltages from the CPU. My game TS profile is very conservative at 5.2ghz dual core and 5ghz all core on the P cores and the E cores are 3.9ghz, with a UV of -155mv. Which is stable. I can hammer stress tests and there are no crashes, yet some games and shader compiling see very erratic CPU behaviours and game crashes.
Only a couple of days ago I limited the voltage cap to 1.4v to try and prevent spikes but from what I am reading and being told, I may already be too late.
This is not something that is easily repeatable either. I've had the games crash on launch, crash on loading screens, crash after a few hours of playing. It is only games though. No BSOD as of yet. Memory has been tested and it does not error. GPU is stable and all the video memory is fine.
Remnant 2 and Silent Hill 2 can crash even with fps limits in place, yet I can play Diablo 4 QHD+ max settings, no RT and no frame cap and I can let it play all day with no issues. Any trouble shooting you can think of I have done and more.
Trent Silvestri I know this is a community thing, but try and get the higher ups to address this issue, please.
