Underclocking stable?

post #1 of 9
Thread Starter 
I've been running my sig rig at just over 3.9GHZ on Prime 95 for about four hours now and I'm expecting it to be stable. CPU voltage at avg 1.47. RAM at 1846mhz 9-9-9-24-41. NB and HT at 2300+.
Assuming that my system stays stable at these settings, can it be assumed that if I were to lock down two of my cores and apply a 3.5 OC and down clock my RAM to 1600 that they would be stable also? Basically I'm asking if I have to run prime again for hours with those new settings. Which I hate doing. Same question if I were going to do an X2 or X3, 3.3, 3.8 etc.......

Nope, but you're going to have a lower lifespan if you wont try to undervolt it too.

If you locked the two cores that are least stable, yeah. If you just lock random cores, you may end up closing out he healthier ones.

Edit: misread, misunderstood.

If your computer is stable at 3.9, then it will be stable at 3.5.

I agree, if just lower your freq lower then it should be stable if you where stable at 3.9.

However some will argue why by a six core system if you only use 4 cores?

True, although some answers I can come up with are: future proofing, some games are optimized for four cores, use less power, because I can.

Something must be wrong with you. This is overclock.net. You're not to be satisfied until there's smoke pouring out of your computer.

Yes. I'm thinking about bumping it to 4.7.

Running the HT link at 2300Mhz can cause instability,though the CPU NB should be at least 2600mhz.
