I'm not trying to do anything excessive here. Pretty happy with a good 100% stable 4.4Ghz overclock. But it must be stable not only running Prime etc. but also entering/returning from S3. This is a must for me.
I have it working perfectly using.
- 44 multiplier
- 1.26 vcore
- Turbo Vcore LLC
- XMP profile1 memory
Max core temp running Prime95 blend at those settings is 67C.
When I use this and fully load the CPUs CPU-Z reports 1.248 - 1.236 and my VID is 1.2360.
So I decided I wanted to stop using a constant vcore and instead use a DVID offset. Seems sensible to reduce power consumption at light load if I can. An offset of +0.04V gives me almost exactly the same load vcore, In fact it oscillates a little higher 1.248 - 1.260, which should work, I think, but it does not. The PC will boot and run Prime stably, but it almost always hangs on resume from S3. This is true for offset values from 0.01-0.05V.
I haven't even tried taking the offset higher because there seems little point in running a significantly higher voltage under load putting the CPU under real additional temp and voltage stress, just to save a few watts at low load!
Why is it not stable when the vcore varies under load, even though it is stable at a lower vcore than set when using DVID? Is there some other setting I also need to tweak to get DVID working? I did think of changing the Vcore LLC to extreme, but generally this seems to be thought not a good idea unless using subzero cooling.
Any thoughts gratefully received!
Hi folks, I'm a newbie too, possibly even a more severe case than Jong1 proclaims for himself (because at least he tried to overclock). You'll see my configuration in my profile, and it looks like I match Jong1's. I never have a reason to put the computer to sleep (as it serves up stuff), and last night I tried plugging in Jong1's numbers. May anyone who reads this please advise on whether those are good numbers for a conservative overclock that doesn't risk damaging my system? I do professional editing on Adobe Premiere Pro CS6 and need all the power I can get, but not to an extent that risks instability or hardware failure. I do like the way (at least so far that I've noticed) the system automatically sinks back down to 1.6 GHz when I'm doing light tasks, but flares up to 4.4 GHz when I'm in the Premiere editing environment scrubbing AVCHD footage. I must say that ticking up the voltage, though, was worrying for no other reason than that it was quite a few clicks up.
Thanks for any advice. For example, since sleep mode is never in the cards, should I go with all these settings except to change from the constant vcore to a DVID offset of +0.04V? And are they all good numbers?Edited by hpmoon - 9/10/12 at 3:17pm
