Yea that is fine, upto +0.3v for 24/7, make sure tho you can cool the CPU as those two voltages will increase temperatures. We also don't know how it will affect haswell in the long term, so no promises, but +0.2v might be okay.

Previously i was OCing the 4770k with open stand on the IGP with only 1 ssd connected.
The results were 4.6,with uncore 41, vring 1.15, 1.9 vin with the gskill ram running 2600 c10 4x4gb with xmp profile on Seasonic platinum 760w.
The mb was nstalled to the case and the intel igp was disabled, amd 6950@6970 was installed,as well as pci Asus Essence and 5 additional hard disks.
After that my OC profile just crashes loading windows.
The case is open and the temps are OK.
So i have started from the beggining.
Eventually what was crasing the oc is the Uncore ratio combined with the DDR speed.
Right now i can reach the same stability on 4.5ghz with the similar settings only with :
Uncore 35 and ddr at 2600c10 with xmp or
Uncore 41 with ddr at 1600c11.
Raising the voltage (vcore/vin/vring) makes no difference.
What's wrong ?
Why is the whole system acts like this with the hardware installed, while without the addintional hardware it runs all right ?
What will i earn/loose productivity wise giving up on the uncore oc and living it on 35 in order to get my ram to 2600c10 ?
Is the stock cache multi bottlenecks the productivity (especially photo editing) considerable ?
Any suggestions to get both uncore oc with the ram speed ?
Thanks a lot.
whynot try to benchmark uncore ratio versus memory speed. it seems that retail haswell CPus have this type of limit where it is either uncore or memory. However PCI-E devices have an affect on uncore as well b/c the uncore ratio also controls the speed of the ring bus and the cache, the PCI-E controller can also be affected b/c it is on the rung bus kind of, and so any extra PCI-E devices or any extra DMI data(extra PCH devices) can produce a lot more ring bus action.

- 48x multi
- 1.30v core
- VRIN External Override = 1.850v
- 45x uncore
-VRING voltage = 1.150v
- C3 enabled the rest are disabled
-LLC = Extreme
-VRIN Current Protection = Extreme
-Pwm Phase Control = eXm
right now just finished a 32mb super pi run will run aida64 in a little bit. But just looking at those settings what else would you recommend to get her stable running 24/7?
Hey wow you are prettyhigh up there with the frequency and everything. If you want to increase staiblity you can do the following:
Lower CPU Core frequency
In that order if you experience issues.
A question or two, first off why is C3 enabled but not EIST? You just want the vcore to drop, but the CPU frequency? I guess that woudl be okay but if you get crashes at idle, you might want to disable C3 or enable EIST>
BTW you can use HyperPI for quick stability, it is super pi but in 8 threads.
