You can either lower the bclck or up the vcore to get it 100% stable.

Hi Gomez! So I uped my VCore two notches from

Thanks!

Ok I think you should lower you bclck to 180 and test to see if you BSOD

Try a 180 base clock and 1.425v

Yes but vcore first then vtt

What you can do is rebuild the overclock higher so follow what we did before to make your overclock

How's it going?

Hi Gomez, I'm currently in my exams but am trying my previous configuration:

And i'm very disapointed in the temps:
 
1- Back then, I had those:
Idle : 40-41 34 38 34 
21h19: 63-65 55-57 61-62 54-56 
21h31: 65-66 58-59 63 57-58 
21h41: 66-67 60-62 64 58-59 
21h51: 65-67 57-60 62-64 58 
21h58: 66-68 60-61 63-65 57-58 
This is about 20% better :) 
 
Which were good, now i'm getting temps arround 71 after 1-2 minutes of Linx. Is it because of degradation or my thermal paste or...?
 
2- [Edit] I uped the VCore a notch and will write a post uppon update.
 
Thanks!

To say the least, it works very smoothly right now! i'm 10/20 runs (after 1 hour 59 minutes) and  temps varies arround 66-72 + I'm running All, which are Problem Size 35536 & 9662 MiB (Memory). Would you tell me to keep them running for another then times?
 
Thanks!
