Load Line Calibration!! (disabled now)

post #1 of 8
Thread Starter 
was really having troubles stabalizing my x4 840 at 4.304ghz and went back into bios and disabled LLC (was on 50%) and NOW FINALLY stable running prime95. Sheesh anyone else have this issue? or maybe my experiences will help out others that dont realize its causing problems in their stabilization... just wanted to pass on the info. temps stable (58c @ 1.55v under load)

LLC effectiveness will depend on how bad the vdroop is of the motherboard. If your vdroop isn't bad then having LLC on may bump your voltage to a point where the OC is unstable. This definitely depends on who makes the motherboard so disabling LLC for one may not be a good suggestion for another. This is why LLC generally has a percentage value so you can adjust based on how much droop you're getting.

I found that (at least on the phenom ii's) that loadline at 100% = least amount of droop compensation
and disabled offered a vrise, pretty crazy amount of it too... i have mine at 25% and i get about .001 to .01 vrise
Im using bios 1.3, when i tried 1.47, my system was unstable, and now my mouse wont click on menu bars to drag, have to use middle mouse wheel scroll, but at least it auto positions the pointer on the menu pulldown.

TLDR: 25% LLC works for me.

I haven't this problem, with disabled LLC i also haven't any Voltage problems.

I run extreme it made it much easier to get a high stable clock for me. But I got the CHV, the higher end boards make OC'ing easy. If I were to disable my LLC I would probably get a BSOD.

ok i messed around with llc and found out that when it is disabled my voltage in cpuz has a higher range it goes to. in bios i have my vcore to 1.55 and with llc disabled my voltage jumps to 1.6 underload. with llc at 50% it stays closer to the 1.55v under load. The thing is for mine to be stable i need the voltages to have a higher range. So vcore is 1.55 and that is fine and dandy for idle but i need it to jump to 1.58-1.6v range to keep from bsoding. kinda of hard to explain. with llc at 50% the volts do not jump up as high as i need them to and i get blue screens like crazy. so LLC-=disabled for me.

Interesting! I learned something new today by reading this because all my experiences pointed to lack of available voltage under load. However you all are right that if LLC is disabled, it /can/ cause overshoots as well due to lack of voltage regulation.
