PS3 Artifacts on the screen

[Nostars240]

Hi, bought a CECHC04 PS3 for cheap. SYSCON logs showed 1002 and nothing else. Changed one of NEC/Tokins with 4 470 tantalum capacitors (I need Tantalizers so bad). I did an undervolt on both chips. Console booted fine, I've installed EVILNAT, MultiMan and webMan. Haven't did delinding, temperatures are ~55 degrees Celsius with 30% fan (in game). While playing GTA IV and GTA V I've noticed artifacting (black squares and white stars) appearing on the screen. Console works fine beside this issue. Is this related to undervolting? I don't like the idea of increasing voltage back to stock. I don't have any other games to test for now, so I'm not sure if this issue related to RAGE engine or its more global.

Hi, I've resolved my issue, increased RSX Core voltage from 1.05V to 1.075V and it now works perfectly. If some of moderators reading this, please delete this post, thank you.

Ah try not undervolting the RSX at all see if problem goes away if so slowing undervolt in a few increments tell the come back then back off a few or the RSX is going that is all ic an think off... Artifacts and strange square can popup if ya get to low special in an intense area of the game where alot of stuff is happening
