I've found that HCI also encounters memory errors when vcore is so close to the edge of crashing, but not enought to chash, I explain.
Doing manual and fixed OC on my 2600x, I've found that [email protected]
was stable on Realbench OCCT, but sometimes playing I've had some crashes, specially on PUBG.
My RAM config was [email protected]
as Ryzen DRAM calculator says, with 1.40 on dram and 1.025 on vsoc. Well, so running HCI was giving me 1 or 2 errors on 400-500%.
Tried rising vdimm and also vsoc until 1.5 on vdimm and 1.20v on vsoc, but same experience, my only way to not hving errors was going down to [email protected]
After some research and test I finally tried to go rise vcore to 1,3125 and errors where solved, and now running [email protected]
with vdimm on 1.38 and vsoc on 1.00v.
So, in my experience try to add a little bit more of vcore if experiencing very few errors on HCI.
