I just recently got a new setup: Intel 4790k, MSI z97 gaming, Patriot Viperx ddr3 1866, and H100i cooler. I was just wondering how easy is it to get to 4.5ghz stable with this setup and if anyone has any tips for me. I use to have a q9450 and could not get it past 3.4ghz stable and I just want to jump right into my setup as perfect as I can get it.

Well, it runs boost at 4.4 stock, so it should do 4.5 just fine.

Is it recommended to turn off turbo boost to have it always at 4.5 ghz i'm very new to this hyperthreading turbo boost stuff coming from q9450

That's what I do. So long as your within an acceptable temp range you should be fine. But it really all depends on how you intend to use your p.c. I guess. When the power bill comes in kinda thing. When I'm not crunching I'm gaming. So I run 4.4 constant. I tell the wife that it's the washer and dryer that's eating up all the power so she thinks she will get a new one. lol. I am also to lazy to research performance diff's overall tbh. I have been at 4.3 or 4.4 for well over a year and my chip seems more than fine.
Does anyone else oc with turbo enabled?

I don't want the wife to chew me out so I'll stay on turbo boost and try for 4.5 or .7 ghz

These newer CPUs OC with Turbo only. Even if you turn Turbo off, it'll automatically enable turbo if you select multis higher than what "stock" is.

The difference now is that previously, turbo would only increase the speed of one or two cores, or whatever Intel said was default for turbo, but modern CPUs allow for full adjustment of Turbo multis, so you can set all cores to the same speed, no problem.

I bought a Gigabyte GA-Z97X Gaming 7 board to go with my new 4790k. The "Optimized Default" automatically OC'd the chip to 4.4 GHz, without Turbo-Boost. I observed the VID, set the VID to 1.19v. Now I run the thing at 4.5 GHz with VID of 1.19v and the Vcore at 1.21v. So I'd say yeah, 4.5 GHz is an easy reach at a low Voltage, with HT totally not needed.

ROFL.


No, it didn't. You CANNOT override the max base CPU multiplier without turbo. This ratio is locked at factory, and what the "K" at the end of the CPU's model number indicates that that "Turbo" settings are unlocked.

Here's how it works:

Note that all of the overclocking on Sandy Bridge, Ivy Bridge and Haswell happens through the turbo multipliers. Effectively, it means that when overclocking any of these platforms, you are always configuring the turbo mode. Even when you apparently “disable” turbo mode! Actually, by disabling turbo mode in the BIOS you force the P-state to always be P0. Therefore, maybe a bit ironically, by disabling the turbo, you are actually enabling it permanently.

Shoulda saved some cash and bought the 4690K then.

Actually, I meant TB was not needed. Sorry for the typo.

As for the rest of what you said: all I know is that you set the multiplier to X, and it goes to X. A default chip installation would be at 4 GHz, and run up to 4.4 GHz on load. In the case of the GA-Z97X Gaming 7 board, the speed was around 4.4 GHz from the start. Now it is about 4.5 GHz. So ROFL all you want. You may be correct, but only technically. I haven't had to set the TB to get max OC since the i7 860. The i7 875k involved setting the multiplier, much like the i7 4770k and the i7 4790k. So call it turbo boost if you want; it doesn't work like turbo boost.

In any case, to re-answer the OP's question, while you roll on the floor getting dirty: yes, one can safely run this chip at 4.5GHz.

You're very right, it doesn't work like Turbo Boost...it's Turbo Boost 2.0. When the socket changed, so did how Turbo Boost operates, and in a big way. Intel is far more friendly to end user BIOS modifications with this iteration of Turbo Boost.

But please, don't get me wrong... I'm not laughing at you, at all. I'm laughing that the OEMs like Gigabyte aren't more clear about things like this when changing options, and how they think that automatically forcing all core to run the same speed and not leaving it up to the end user is a good idea. Yet, at the same time, since you have a "GAMING" product, I understand WHY it does it what it does. Take a look at the list of motherboard reviews posted to the front page here, and note who the author is. These board makers should have noted on the outside of the box that this is how it works, that there are automatic speed boosts, and memory modules should state that when enabling XMP on most modern motherboards, and automatic multiplier increase will be applied.

Just to add to the fun (at least I am having fun now with the 4790K!):

I have been messing around with tons of settings and voltages, get no good results, went back to default (=4400 turbo).
But since a couple of days I am having happy sensations with this: I just uppd the multi to x48 and the voltage to adaptive 1.275v (only core volt, all the other settings left to AUTO) and -
WOOT - I am stable and happy, cool temps, big results. Voltage hoovers from 1.2 to 1.3 v when in 4800 Mhz mode.

i just can't believe this. Seems like indeed, like CADAVECA says, this newest family of processors is the bomb! It does all for you!

EDIT: not so quick little parrot: Battlefield 4 crashessssss

This is what I'm starting to dislike about Haswell after just a week back into the game. I enjoy it NOT being so easy. Oh well. Guess it's just the way of things these days. It just diminishes some of the "magic" of the tweaking hobby.

Oh dont be like that Paul, these chips are barrels of fun ;)

theres alot of tweaking options for these chips.

LOL. I don't think anyone who has been playing with hardware for 10+ years would disagree with me. I'm not saying it isn't still fun. I'm just saying that the overclocking hobby has changed to become more inclusive. In some respects, I think that is a good thing. In others, it is not. This sort of shift always makes things easier, and if the best part of a hobby is the challenge, then the satisfaction is inevitably diminished.

I digress. Nothing like a moderator derailing a thread. Carry on. ;)

lol, yeah I agree. This isn't as fun as clocking an AMD chip however the hasswell is better (more complicated) then sandybridge for sure.

Dave, can you qualify that? I thought that only applied to mobile chips, where power saving really *is* critical. I'm pretty sure my IB turbo's all cores when under full load (@ stock).

Why turn it off? Do you need that kind of speed when its sitting there at the desktop, not to mention shortening the life of the chip while not processing much of anything?

I OC with turbo enabled so that at idle and browsing it runs at like 1.8ghz, which is perfectly fine, and once i start applying load and what not from gaming or video editting, itll boost to my OC setting when I need it.

You have a very good point. For me, my chip is always running @ 100% for crunching with no down time other then while I game.
"Depends on how you intend to use your p.c. I guess. When the power bill comes in kinda thing" That's why I mentioned this. Even with turbo on or off it matters little for my daily usage scenario.
A 3770k running at 4.4 on 1.25 volts staying under the 80 threshold should be fine for longevity or so I have been led to believe.

It's not really derailing the thread though. To sum it up in a way that rolls it all together, Intel has purposefully adopted overclocking as a sales item, specifically with the "K" CPUs. On any given week, all CPUs sold under the "K" moniker should clock identically, and Intel has tuned their process specifically for this, so they know where on the wafers to go to in order to get us decent chips to play with. They will also replace a chip "killed' under OC with no questions asked, for a small fee (ie, $25 USD), so you can get a CPU, clock the snot out of it, and then return it for a fresh one that still carries the standard warranty.

Anyway, part of that is the CPU clock speed, since this is part of what most "enthusiasts" seem concerned about. That 4.6 GHz clock that I've been talking about in my own reviews for some time is kind of the base line Intel shoots for, although some weeks it's only 4.5 GHz, or maybe it goes higher yet, @ 4.7 GHz. The voltage required to get there may vary, too, but the end power consumption should be equal. What that leaves us, for the skill-based side of OC, is cache speed and memory tweaking. Unfortunately, since DDR3 is old, and already greatly exploited, there's not left there to play with. Most "pro" clocks have their good sets of PSC and Samsung ICs, and maybe a set of Hynix MFR for high clocks, and current chips have let memory scale far higher than ever before, but it's not like we hear about records being broken any more.

So, the normal user gets a decent OCing platform, that's easy to use, and forgiving, and us older die-hard clockers did the R&D for it. We get to be the gurus that help people out, who then get great results, and everyone is kind of happy, since it's all backed by a decent warranty.


Why turn it off? Do you need that kind of speed when its sitting there at the desktop, not to mention shortening the life of the chip while not processing much of anything?

Everyone OC's with Turbo enabled. When you "disable" Turbo, you are actually forcing Turbo to be ON, permanently, as I posted above. There's no need to be concerned with CPU longevity these days. A chip will overheat and throttle long before you're putting it in a state where that'd be a concern, as long as you haven't de-lidded. People have complained about hot-running CPUs, but really, this is a safety factor that will keep your CPU safe. We just need to not be so concerned about operating temperatures, and push right to the limit.

Straight from the horses mouth. I like what I am hearing. So is it safe to run @ 100% in the low 90's for Ivy. Lets say I try 4.6 @ 1.2x and during IBT I max temp to 93 am I safe to crunch with that so long as it's "stable"?

Yeah. I mean, at stock on a stock cooler, you can expect these temperatures anyway. If it was a problem, the stock cooling would not allow this. Temperatures don't kill. They have other effects. And the "Poor TIM" of these chips is there to ensure you cannot push to unreasonable current levels, and if you do, the warranty is there to cover that.

You can find a video on YouTube of Intel reps stating this, even.

intel would not have an agenda for us shortening the lifespan of hardware which forces users to upgrade every 4 or 5 years would they?

I was just going to comment to @MxPhenom 216 about his comment about sitting at full clocks but I see @cadaveca summed it up :rolleyes:

I trust the Dave and when he says it can run at whatever clock at idle and not hurt anything I trust his knowledge :fear:

lol it's all good, shit... I sit here @ 4.6ghz all day but at only 1.184v and the rest, yeah it's all good :peace:
