Base clock overclocking

How dangerous is baseclock overclocking, can you do it on locked intel CPUs and what is a safe overclock on the base?

@Zando Bob has experience with BCLK overclocking, if I recall correctly.

Thanks

Only on X58, and mostly trial and error, lol. There's some bois (IIRC Ground and a couple others) on the X58 thread in my sig who have binned tons of chips and know a lot more about BLCK overclocking and average safe OCs and clocks for most X58 chips. Don't know much else beyond that, I know older platforms can do BLCK OCs as well, newer ones are much trickier and become unstable really quickly.

out of luck. If you only use SATA based storage then you can probably hit anywhere from 104 to 107MHz BCLK, any more than that the system just wont get stable no matter what. If you have PCIe based storage then you shouldn't touch it at all, I've seen people corrupting their NVMe SSDs because of it. It is safe as long as you dont touch the voltages

Yep only using Sata drives at the moment. 107mhz isn’t that bad of news to me that’s still going from 3.5ghz to 3.74

if even that. Some boards dont let you touch it at all or just top at 104

Is 240 MHz worth the effort?

Maybe on a Pentium 4, but 6.5% clock increase at the risk of system instability?

Slight, slight improvement in benchmarks, little to no difference in games. The difference between 4.4 and 4.6Ghz on my 5820K in gaming and real world use is about 0, and I think it's only a few more points in CB. It is a massive improvement over the base 3.6, but that's an 800MHz increase.
