So far I'm reluctant to attempt to pass that 1.4v threshold as I'm told the 22nm architecture is a lot more sensitive to voltage than Sandy Bridge-e was. I wonder if that rule holds true under custom watercooling, though? With powerful cooling I wonder if it's safe to move vcore up into the 1.45v area? I feel confident my chip would do 4.7 or even 4.8 at 1.45v, I'm just not quite bold enough to try it yet. lol
are you on a 4960x? I can't seem to pass the 4.6 GHz Evan at 1.4 and you rite 22nm less volts forsure

Today I tried to increase the clock a small margin from 4.6ghz to 4.623 at 1.344v by changing from 100x46 to 100.5x46. for my 4930k.
I used this because going to 4.646ghz required an increase the volts.
It will run P95 at 4.6ghz@1.344v fine but to run P95 at 4.7ghz takes heaps more volts

Testing today with the PLL voltage was interesting. With my last bios and i7 3820 I used 1.8v and above. What I found today that running cinebench was unstable at 1.7v and above but stable at 1.59375v in bios. Unstable again at 1.575. I had no idea that lowering the PLL could help so much.

No, I'm on a 4930K, I just kinda "merged" into this thread because they're essentially the same thing.

FYI, reliable binning has shown that only about 20% of Ivy Bridge-e chips can go above 4.6ghz at reasonable voltage, so it's not too surprising that you haven't been able to exceed that. 4.6ghz seems to be the average, so if you're comfortably at 4.6 under 1.4v I'd consider yourself lucky to be in the better half of the curve and leave it there (something like 30% can't exceed 4.5ghz).

exactly my thinking too I'm trying one more chip but I doubt it will be able to do any better 4.6 seems to be the norm at 4.6 its still faster than my 3960 at 4.8:D

Hay about the CPU pll my auto setting is 1.8 is it worth it to lower and could you maybe give me a brief description on its purpose thankyou

So I got my 4930K installed today and will be shipping off my RMA 3960X tomorrow. Been playing around with the OC all evening and am somewhat disappointed. As it sits right now I can do 4.6GHz at 1.375V and 4.7GHz at 1.48V but 4.8GHz ain't happening. Instant BSOD at 1.5V and I don't really want to go beyond that. ANyway, I've been running a 5GHz 3960X for two years almost and the 4930K is definitely slower at 4.7GHz which is killing my bench scores (I lost 1k points on my 3dmark11 physics score). I'm running the IB-E 4403 BIOS on my RIVE already so that's not the problem and my temps are fine even at 1.48V (mid-60C's under full load) but the performance just isn't there at this clock speed. Looking like I may have to keep the new 3960X Intel sends me and return this 4930K to Amazon...

Bummer, that's disappointing to hear. frown.gif I think the delta is around 200 mhz, so you'd probably have to hit 4.8ghz to match your 3960 at 5.0 -- and we've already seen that almost nobody hits 4.8ghz on IB-e. That said, if I'm not mistaken, a SB-e that can do 5.0ghz on reasonable voltage is sort of a rarity, too, no? Why would you upgrade when you already hit the silicon lottery last time? Lightning rarely strikes twice in the same place. wink.gif

It sounds like your 4960 is practically identical to my 4930. I'm currently cooling it with a H80i, but it gets pretty warm at 4.6, and too hot to even run at 4.7, so I'm probably going to build custom watercooling for it in a few weeks. Though it surely feels like a disappointment to you, I do believe we're in the top half of the curve -- you even more than me, as I'm pretty sure 4960X has been shown to clock even worse than 4930K.

When you get your 3960X, maybe you could run a few benchmarks with exactly the same setup and memory clock so we can compare apples to apples? Like Cinebench 3960X @4.7ghz vs 4960K @5.0ghz -- that's the sort of head to head comparison I've been seeking everywhere but have yet to find.

Check out my asus club thread I have a list of current 4930s and 4960s and they top speed / voltage if it helps along with batch numbers. Did enough tests to where im exchanging my 4960x for a 4930k right now
