44x cache @ 1.27v is not too bad at all. nice!

max temp is good too.

i find it interesting that your total power draw is so low. It should be higher than 94W, but that might just be due to a different sensor implementation on MSI motherboards.

You can increase VCCIN in your bios a bit higher. It's at 1.85v atm but you can raise that to 1.90v if you want (obviously it's not necessary since you say you might be stable with 1.85v)

(@Darkwizzie This is a very interesting screenshot. 1.43Vcore and only 1.85v VRIN??)

edit: I read your PM. Sorry, I don't know where the LLC settings are on your MSI mobo frown.gif

how is Results? I have voltage at 1.430v for 4.8ghz idk if that to high but seems stable and temps aint gone past 84c

Due to uhm, random OCN website weirdness, I'm finding it hard to edit my posts with the correct format, so I'll just flat out double post. It's my thread, sue me. :p

Yes, you can probably hit 1.3v no problem. But consider what you're doing: You're upping the risk... not by much really, a small amount to be sure, make no mistake. But for what? An extra 100mhz uncore has the performance difference less than a tenth of a percent. And that's in CPU benchmarks. It's purely a psychological reason.

 

Having said that, I'm not here to dictate what reasons you need to do something, only list out the facts of the situation. I myself am at 1.28v Vring.

Also, friendly neighborhood reminder from Darkwizzie to come back and list your overclock settings when you're done!

Well thanks for the help, I tried those, did not succeed at 4.4 Ghz and I went as far as putting a vcore of 1.32. BSOD in a few seconds after starting running small fft's in p95. I guess I just have a bad overclocker again. I'm stuck at 4.3 Ghz with 1.262 vcore.

Btw CPU Level Up setting does not have a disable option, it's just 4.2, 4.4, 4.6 and auto. That's why I had it in auto. Also Initial CPU Input voltage at auto was set at 1.710, tried it in 1.800 and 1.810 both in Initial and Eventual, did not work :/

i find it really disheartening to hear of other users who received poor overclocking chips. I've been in your position before (44 @ 1.375v) and I truly feel your pain.

at some point, it really is just worth considering dropping 25 bucks on the Intel overclocking warranty and touching your chip with a AA battery lol
post #6784 of 19539
I don't think such a statement is possible because it depends on all these factors, the peculiarity of your own system and where the weaknesses emerge, etc. Hardware today is extremely complex and each component is unique.kA7FwG

Hey guys, this is hopefully a quick question.

I'm struggling to see the difference regarding vcore voltage between adaptive mode and manual mode. From my understanding adaptive mode should allow the core voltage to scale up and down with the CPU utilization. However, when I have it set in manual mode with a voltage specified, the voltage still scales down. I'm running in adaptive right now anyway, but if manual behaves the same... why not run in manual mode all the time?

I'm running a 4770k with a Asus z87 Sabertooth. 4.5ghz with adpative voltage set at 1.2v (during stress, OCCT reports it at 1.216).

Asus mobo's which have the C States and EIST set to Auto (which you probably do) results in adaptive voltage even in Manual voltage mode thumb.gif I have the same with my z87 Gryphon.

I'd personally leave it in manual mode with C states + EIST enabled like you currently do, as what you're experiencing is ultimately what people who don't have this luxury are trying to achieve by switching to adaptive mode. Furthermore, you won't have to worry about certain environments bumping your Vcore higher than you anticipate smile.gif

I took the picture before I installed HWMonitor, but my Vcore seems really high, although it is listed under the motherboard and not the cpu.

I stopped the test immediately in a panic when I saw that, but I feel like that's actually not the Vcore for the cpu, or else my temps would be out the roof.

I don't see where it says 1.792 on there. You have three windows open and in OCN pictures, the picture is like 5000 x 5000 resolution. If you did hit that high, your CPU would be dead by now so the good news is, you probably saw it wrong. You most likely saw Input Voltage instead of Vcore. Input Voltage for 1.792v is OK and maybe even on the slightly low side. Aida is picking up a Vcore of 1.212.

good luck in reaching 4.5 smile.gif

So I was doing stress testing last nite at 4.7 cpu ratio and 4.5ghz nb freq tested for 5hrs didint crash biggrin.gif but like 7hrs it Crashed was gonna take pictures at 7hrs if it made it but failed
I did manage to go from 1.27v to 1.28 and it reads this and idk if I would be stable by +10v will stress test today see what happens

oops wrong pic here it is
post #6790 of 19539
Yeah the Vcore reading under the Motherboard dropdown is reading the CPU input voltage for some reason. I figured the Core Voltage under AIDA was the Vcore but I just wanted to verify with HWmonitor.

I don't know how the picture is showing a 5k x 5k resolution, every way I try to go about it its only showing 500x1000

Anyway with these settings I was stable for 13 hours before I stopped the test but I don't have a screenshot for it, so lets just go with 11 hours from this screenshot.
