Minor 2600k overclocking question - Page 4

post #31 of 33
Glad it's working better.
Yes, PLL Overvoltage on the F3G /F3h/F3d (or whatever the latest betas were for the UD5, UD7 and UD4) is a lot more stable than it used to be.

BTW LLC standard is the same as auto. Not even sure if Auto ever takes it off standard, anyway. Possibly, auto might change it to LLC1 or LLC2 at high multipliers (like over 50).

If you're stress testing or using longterm voltages, it's better to use LLC1, and raise the BIOS voltage about 0.05v higher than your "desired/required" load vcore (the vcore you need to not BSOD at load), than it is to use LLC2. LLC2 is for benching, and having the CPU vcore rise at load isn't really the most healthy thing for it. So if you're stable, for example, at a LOAD vcore of 1.42v with x47 multiplier, it's better to set the BIOS vcore to 1.46v and use LLC1, than it is to set the bios vcore to 1.37v and use LLC2.

Using LLC2 to do the "reverse" of vdroop also gives you the risk of a BSOD at anything that runs on 1 core/thread or light load, since the voltage will be too low for full stability. And if you ARE fully stable at light load, you run the risk of having TOO MUCH load vcore with LLC2.

BTW check your PM also.

Dually noted, ill go change it back to LLC one with a different vcore, the vcore does not appear to change in the bios when I change it.. Is there something I am missing with this?

The vcore on the left side is the VID. This is the vcore that the CPU requests for that multiplier. That's the "vcore" that the CPU will get (before droop/LLC) if the voltage were set to Automatic. It's usually enough for the CPU to at least POST into the BIOS itself. The only VIDS that are guaranteed for stable operation (at up to 98C DTS/diode, 78C Tcase) are the ones for the official turbo multipliers, X34 (stock) to X38.

Sometimes, but not always, a CPU with a higher default VID will either be a worse overclocker, or will have a low multiplier wall. Some have low multiplier walls, but overclock on low vcore. Some have low multpilier walls and require 1.4v for 4.5 ghz+PLL override enabled (the very bad chips). Some have high multiplier walls and are good clockers at decent vcore (5 ghz, 1.416 to 1.428v load voltage, x49 multiplier wall PLL off, x54 PLL on, but run hot).

It's been a 'general' trend that cpu's with low default vids at 3.4 ghz will have higher multi walls, but there have been some 1.25v VID cpu's that have reached 5300 mhz at 1.45v stable....
