3770k 4.8ghz good chip weird behaviour - Page 2

post #11 of 12
First off 1.36v for 4.8 would be low, that would be a very good chip. I would say the average Ivy needs over 1.4v for 4.8, and that assumes they don’t hit the wall along the way. My above average 3770k chip needs 1.41v for 4.8.

I would be happy to try to help but you would need to follow the advice in my post above. Use the guide I linked, copy the settings, and use Prime95 version 27.9 to check for stability.

OP you need to follow what justanoldman is saying if you have to get it stable, I have my rock solid stable at 4.5Ghz offset LLC on high, no delid, all C states enabled, virtualization enabled, multi-thread enabled... practically most advanced settings are enabled. Vcore @ 1.288v and yes prime 27.9 is better at stability tests than what you are using. You may not even have been stable from the beginning.

Another quick and dirty way of knowing whether you are really stable with that IBT test is run WEI, if you pc isn't able to complete the rating then you are definitely unstable, if it does, go to the event-viewer and check for warning Internal parity WHEA error event 19. If it is present and it reads processor core (0-7) cause a correctable error that the system has corrected, you are definitely unstable even with that IBT test.
