beginners overclocking problem(s) (i7 920 / Asus P6T Deluxe) - Page 2

I can only see needing 1.3v QPI for 6 modules (maxed out memory slots) or ram running 1866+. You should be able to drop it down to 1.25v if you are not doing any of the previous. As for vcore, have you enabled loadline calibration to prevent voltage drop under load? That will allow you to lower the vcore.

thanks for the reply, dude

ive already enabled Load Line Calibration. i just tried 1.25v QPI and it didnt work, not sure what the error was. how do you get the BSOD to stay up instead of rebooting straight away? i put the QPI to 1.3v after i was getting 0x124 errors while trying to make 3.8GHz. my memory is @ 1523MHz

*edit = i have 3x2GB DIMMS of Corsair Dominator memory (1600MHz)

I would say that 4GHz is a very good overclock for a 920 considering stock is 2.67GHz. Looks like ur chip aint so bad thumb.gif. If you do want to run HT then I would recommend bumping down to 3.6GHz or 3.8GHz and you could probably get away with 1.3 or less vcore resulting in less heat. (4GHz w/ HT on gives me 75deg and 4.3GHz w/ HT off gives me 75deg). Also, I noticed your qpi is 1.3v, you could try bumping that down to around 1.25v and see if it is still stable. If it is I would try going even lower with it until you find unstable and then go a couple bumps above it. Decent cooler and case so no worries on that clock with those temps. Ambient temperature makes a significant difference in cooling as well so if your temps are good at the warmest time then you are laughing. biggrin.gif

EDIT:

I didn't see the previous posts before posting. As with the BSOD I do not know if you can make your system hault at it or not. I'm usually around to see when mine does it. You may need 1.3qpi but I would try bumping it down in 2 increments until unstable. Also try changing multiplier to something like 191x21 or 200x20. If your memory frequency goes over 1600 you may start to get memory crashes as well, unless you overclock your ram or loosen timings but for now don't worry about that.
