Default Overclocking non-K Haswell?

On Ivy bridge non-K processors allowed limited overclocking by 4 cpu bins (400mhz) over standard turbo frequencies. Apparently this is no longer the case:

http://www.hardware.fr/articles/897-...-ailleurs.html

Does anyone have confirmation of this? Maybe it's just the test motherboard that was shipped out to reviewers?

Or can you overclock using the CPU strap as this review suggests?

I don't think so, everything is locked down pretty tight with the non-K series chips.

So all you get is multi core enhancement? :/

And a slight BLCK clock increase. Maybe 5% there.

This confirms that limited overclocking has gone

Ivy non K is faster than Haswell non K...
now the i7s/i5s are as locked as i3s (and lower) already were since Sandy Bridge.

No...

Only way you might get that is if the IB uses a multicore boost board that auto OCs turbomodes.

so,
yes...

or you can set manually on ivy/sandy bridge, and you cannot on Haswell.
200-400MHz more should be enough to beat Haswell for most things.

the funny thing is, there is one less reason to buy a Z motherboard if you are not buying the K CPU.

True. This is just a bizarre thing to worry about though.

Limited OC of Ivy non-K only happens with good boards on custom builds. I would think that a large majority of OC'ers just go for the real deal and get the K in the first place, and with pre-built HP/Dell/etc, you can't overclock anyway. It's not like the K series is a lot more expensive.

However, the point is more valid with i3s. I imagine some people building i3s currently like being able to do some minor overclocking, and in that case i3 Ivy should be faster than i3 Haswell after overclocking, outside of the very rare/specific cases where Haswell IPC is notably higher.

You will never get more than 200Mhz. And 200Mhz will not make IB beat Haswell in the higher end.

Z boards never made reasons if you didnt buy K models in the first place.

the price difference at the moment is $60 (i5 i5-4430 to 4670K),
It's hard to have any hopes for a cheaper unlocked CPU from intel at the moment.

I totally disagree, the difference can easily be bigger than 200Mhz,

and there were plenty of lower cost Z75/Z77 MBs that made sense with a cheaper i5, and you could get some overclocking done,
tomshardware used this to an advantage for their $600 gaming PC,
http://www.tomshardware.com/reviews/...pc,3443-7.html

that was a 3.1-3.3GHz working at 3.5-3.7GHz which makes it as fast as more expensive models.

another example of a free extra 10% of performance with locked ivy

I have the 4570 (non-K) version. What's the normal temperature for an i5 cpu? Mine seems to be around 55-56C idle in UEFI/BIOS, is that normal?

I'm running on an mATX board, no fan at the moment..

Do you think it's ok to keep it that way, or should I get some fans? I'm running it on a mATX board/case (a bit crampy but there is space for 3 80mm fans), Asus B85-G and HD7850. I haven't ran any games yet, just installing OS at the moment

All new build and I havn't upgraded in 5 years so I'm really not sure..

What kind of case? Recent cases don't use 80mm fans anymore.

A cheap matx case is the Fractal Design Core 1000, it has USB 3 and it is quite nice

I have the Jonsbo V4 http://jonsbo.com/en/products_13_1.html. At first it was between that and the Fractal Core 1000, but it looks so much nicer and smaller (no external dvd bay though)

So you cannot change the base clock of an i5-3470 to 125MHz?

Certainly not on Ivy no, you can add 400mhz to the clocks though.

that's only available for Haswell K CPUs, or any Sandy Bridge-e i7 (including the 3820)

Intel probably figured with thermal thresholds set at artificial lows that nobody would buy k chips if you could just use the bclk.

Or maybe it just has something to do with the additional features that aren't present on the k versions.

So haswell i3 bclk overclocking is out of question?

Looks like I'll be buying an apu... again.

Well duh. Intel has disallowed bclk over clocking since SB. They brought it back for Haswell and its only for the K series

And it's lame.

Overclocking used to be about squeezing value out of every cpu part you could afford, not "you can't play unless you dump wads of money on top parts".

Intel is pretty lame. Taking out the limited extra turbo bin unlocking, and limiting BCLK unlocking to "K" SKUs, when they also have an unlocked multi.

So much for Haswell being an overclocker's chip.
