Recently apps have started to crash on me. I droped my oc to 4.1ghz and load voltage to 1.104 and core 0 would crash while running prime 95. I got it to stay stable at least for a few minutes by feeding it 1.176v. The cpu itself ask for 1.185 at stock so i think im safe. i have recently droped my cpu pll voltage from 1.7 to 1.6 and this started happening. would lowering voltage hurt the cpu? Also i think 4.1ghz is a nice speed to be at, i dont think im missing to much, but 800mhz is no insignificant number. This cpu has been at 5.1ghz but i cant get it stable with my cooling. Im sure on a good WC loop i cant get 5.1 with no issues. but core 0 is starting to worry me.
Set the PLL voltage back to 1.8v.
There's NO reason to lower it. Sometimes lowering it to 1.7v helps shave off a few C's off temps, but the only people who should be doing that are the 5 ghz+ overclockers who are dealing with temps in the 80's. They lower the pll voltage to try to lower the temps, since lower temps=higher stability. But you never know what the drawbacks are.
Some people have to RAISE the pll voltage to 1.9v+ in order to get very high multipliers to work, like X55 (assuming PLL Overvoltage is enabled--which is a DIFFERENT thing than "Pll voltage". If you look in the Intel tech documents, you will see a different PLL voltage shown, which is listed at 1.5v, and that's probably the one that's being "overvolted" to get higher multipliers to work).
And 1.104v is FAR too low for 4.1 ghz load vcore :/ That's a voltage you would expect at 3.4 ghz, not at 4.1 ghz.Edited by Falkentyne - 3/25/11 at 4:42pm
