1800x & MSI Pro Carbon - Are the Vcores Safe?
1800x & MSI Pro Carbon - Are the Vcores Safe?
After much trial and error, I now have two reliable OC options to consider.
I’m confident in a stable 4Ghz and a 4.025Ghz setup.
Manaul "static" voltages were applied (no offset available at the moment).
Temperatures sit between 75 and 84 degrees, though this likely doesn’t include the offset effect.
4000Mhz OC: vcore stays at 1.392 under load; NB voltage around 1.1 or slightly below.
4025Mhz OC: vcore remains at 1.416 under load; NB voltage again near 1.1 or below.
Realbench performs well on both, but the higher frequency version needs a vcore of 1.43 or above (not yet tested).
CPU-Z data can be found here: http://imgur.com/a/TTtdb
Speed limits are lower than expected due to bus speed constraints I can’t adjust right now.
Should I opt for the slightly slower OC, or stick with the best one? – Normally I’d go for offset vcore, but I wouldn’t push higher since voltages rise significantly!

Word on the street is anything under 1.45v is OK. AMD is saying anything 1.45 and up can impact the longevity of the chip (but they can't really know....). Personally I wouldn't hesitate at 1.41 or at 1.43 at all but I don't mind getting a long life out of a CPU. I've also never had a CPU "fry" on me after several years of pushing overclocks.
If you're even remotely concerned, consider that there's no way you're gonna feel a difference in the real world between 4000 and 4025...

The main issue with 4000 is it occasionally appears as 3999, which would irritate someone with a minor OCD tendency.

You can be content with 4GHz instead.
Hey guys - I think I'll go with the 4025 OC profile. I haven't tested the 4000 for stability yet, but the 4025 seems fine.
Yeah, sorry about that OCD thing - I really don't like seeing 3991.
Also, according to the MSI forums, the current Pro carbon Bios are pretty un-optimised. Users can get much higher OC's on the B350 Tomahawk with the same CPU, but use less with the Pro Carbon version, even with more VRM. Beta versions are expected soon.
