So I'm at 4.2ghz and 1.35v...stable in prime95 so far, temps below 90.

Hooray?

EDIT: So what about hyperthreading, turbo boost and all that? Would disabling any of that help? I remember disabling hyperthreading used to help get higher clocks on i7s, but that was back in the i7 920 days rolleyes.gif

Now about that VRIN thing. I was told to try out 1.6v. And that CPU vcore and VRIN is suppose to be around the same. Is there any hold on that?

I'm getting the entire Haswell setup this week here. But it never hurts to ask ahead smile.gif

Err, I guess it could potentially lower temps. I will test it myself later today for you. My guess is no but I'll wait for the data to come in before I say conclusively.

 

Vring is a tricky beast. Here is my take on it... you typically only need to worry about it when you're running a high Vcore. Say, 1.35v or higher. Lower than that typically your motherboard auto-rules have you covered. Yeah, I said typically, I have not tested all motherboards. All I can get from other motherboards are secondary sources from other people's experiences. But, the general concensus (and this makes perfect sense), is that your Vrin aka Vccin aka Input voltage (why so many names??? Pick one and stick to it, motherboard vendors!!!) needs to be higher than your Vcore under all circumstances. Your input voltage is all of the voltage going to the entire CPU, CPU core is a large part of the CPU but not all of it so it makes sense. How much more? Some people are saying 0.5 more.

 

My experience and from what I've mostly read about other people's experience, under 1.3v vcore, input voltage doesn't need to be touched. Once you go higher you can try 1.8v, 1.85v, 1.9v, 1.95v, 2.0v. I suggest not passing 2.0v. One report said 2.2v killed a chip.

 

There has also been a few people saying that setting the input voltage way above what you need can also cause instability. That I do not know, I've only heard and most of it are simply assumptions, but it may be worth considering. Maybe when you overclock, as you go step by step, record what crashed and what happened when, maybe that'll help you.

 

Good luck with Haswell.

Not a lot of talk about that because it's assumed if you're going to get a 4770k, you're out for the hyperthreading, otherwise why pay an extra $100? Yeah, hyperthreading may up your temps but if you turn it off you might as well have gotten a 4670k, lol.

 

Your CPU is still below average unfortunately but at least it's not as horrible as I first thought, lol. That's always good to find out.

 

There has been no talk about turbo boost, I'm assuming it's not doing anything.

No it's manual. I never used adaptive. If you have all C-states enabled you should still be able to idle like at stock speed. (0.1v 700mhz or something like that)

So i really don't get it, sorry if i spam but i need help to understand this, i can boot in to desktop with like, for examples;

I boot in and browse ocn @ 1.309 VCORE / 1.809 VCCIN

But when i got to 1.310 VCORE / 1.810 VCCIN
It wont even post to logon screen?

Same with 1.311 / 1.811

Then suddenly i can boot again on 1.312 / 1.812

Wow, that's interesting. What core/uncore multipliers are you on right now? I'm unsure but my guess would be you're setting too high of a voltage for a multiplier. That's only a guess though.

Your input voltage is all of the voltage going to the entire CPU, CPU core is a large part of the CPU but not all of it so it makes sense. How much more? Some people are saying 0.5 more.

My experience and from what I've mostly read about other people's experience, under 1.3v input voltage doesn't need to be touched. Once you go higher you can try 1.8v, 1.85v, 1.9v, 1.95v, 2.0v. I suggest not passing 2.0v. One report said 2.2v killed a chip.

There has also been a few people saying that setting the input voltage way above what you need can also cause instability. That I do not know, I've only heard and most of it are simply assumptions, but it may be worth considering. Maybe when you overclock, as you go step by step, record what crashed and what happened when, maybe that'll help you.

Good luck with Haswell.

For VCCIN I've been leaving it around 600mV higher than vcore, in the screen above it was at 2.2V, had it at 2.5V when benching 1.9V vcore, & tried as high 2.7V going for higher clocks.
Mainly benching & short time stability testing like 10 runs of IBT, haven't run the 4770k 24/7.

I do want to test the XTU benchmark for stability on haswell. When getting the 3930k set up I used the XTU benchmark for quick stability testing since it is considerably tougher than cinebench (been using cine to see if at least stable enough to bother running something tougher).
So set the 3930k for 4.8Ghz & started testing & upping voltage to where I was XTU bench stable, I was surprised that when XTU stable, it is also 10 pass max memory IBT stable. Started it folding for the September folding competition, still going strong a couple days after.

I'm using

4500 Core
3500/3500 Core

Forgot to mention i set the Uncore voltage to 1.115 (Bios)

Currently writing this on 1.332 / 1.832 (Bios Voltages)
However i've been able to post and write on ocn with much lower voltage also.
I'm literally going what the f right now..




Those are voltages i've been posting on but anything between is failing..

Only the 124, constantly.

However i've noted all the diffrenting codes on the 124

FAD028
A06C028
066028
FFD028
068028

Well basically i've got an A4 filled but they all start with 124 and all contain 028.
