so whats wrong with that? with asus and asrock mobo the vcore is about .025v higher than vid aslong as you no that it shouldent matter

In my case for example, versions 1.65-1.67 just show a FIXED number as Vcore, which is the VID. No adjusting values if C states are enabled etc

ive tried 1.64 and that shows my stock vid of the chip no matter what i set it to in bios. 1.65-1.68 show me the vid i set it to

What do you think guys, I have two settings that looks stable: (core/uncore)
I test with 20 passes of x264 and 5x XTU benchmark (not the stress test, I found benchmark to be a quick test to check stability beofre 2-3h of x264)

- 41/41, VID 1.20v and vcore 1.216, VCCIN 1.8v
or
- 43/39, VID 1.25 and vcore 1.264 and up to 1.280 on one core, VCCIN 1.9v


Is the increase in vcore worth it?

I may try 44/39 with same settings, note that my ram is at 2400mhz.

CPU clock is King. You won´t notice much of a difference with the cache clock. I would let the cache rest at 39 and try how high you can go with the cpu clock as long as you are comfortable with the temps and later you can look how near you can get the cache clock.
But as I said, the gain by upping the cache clock will be minimal.

Vcore is "save" up to 1.4, if you can handle the temps. I would say everything up to 1.3 is worth it for a gain in cpu clock. After that you´ll have to decide and it depends on your chip. Mine goes ape**** on temps after 1.32 so I don´t go higher. Waiting to delid.
And I´m on a water loop.

turns out i need aornd 1.475v for 4.7Ghz which is a little to much for my liking and IBT would probably hit 90c+ redface.gif


What do you have your load line set to?? I see you put LLC1 ? does that mean you selected 1 thru 8-10 ? or LLC 100% if so...I would say you might be able to lower your vcore some if you put the llc to 100% as this will boost your actualy load to the max input voltage or within a notch or two...having to low of a llc while running a higher vcore and overclock will cause lots of instability issues.

also to note what do you have the system agent voltage boosted to? your running 2666mhz ram this requires a boost in system agent voltage...if not youll havto boost the vcore much higher to compensate fot this as well as input voltage. rec system agent voltage for 2400mhz++ is 1.15v-1.25v or offsets of 0.150-0.0400v

If i set 1.35v, 1.68.0 shows 1.35v 24/7 for me. It doesn't change, it displays the sensor that Hwinfo calls "Core VID". It labels it as "Core Voltage" i believe, which is incorrect.

Version 1.64.0 displays the sensor that Hwinfo calls Vcore. It sits at approximately ~0.7-1.384, dropping lower with c6/c7 state. The same is true for quite a lot of people - though behavior in general is quite varied, it's very difficult to keep track of what is broken in what ways for which motherboards etc

it adds heats etc and more instability issues. I always just follow the keep it within 500mhz of the oc so your at 4.6ghz try uncore at 40 or 41 lower the voltage and try 4.7ghz again. not saying its going to happen just saying ive found this to work wth several chips allowing higher core clock while keeping the uncore ither stock or below 43x

I usually keep my uncore right around 42x for any overclock including 4.9/5.0ghz..this keeps temps lower and vcore lower.

i test with my uncore @ 35 until i get a stable multi then ill start upping my uncore . ive also been through quite a few chips so im pretty familiar with ocing them now.......6th one is on the way hopefully it's a good one


anyway it's 10 am here and i havent slept yet so ill be back this afternoon tongue.gif zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
