Overclocking H67. What do you think?

[dougri]

Well, I have emailed Asus asking about this, and will email Gigabyte; and will post what they say.

I've talked to a system builder through email and was told the H67MA-UD2H definitely supports overclocking, that they've seen a demo of such from their vendor, and that the misinformation was due to the inability of ES (engineering sample) to overclock on H67. It is not clear if they were referring to ES CPUs or preproduction mobo, but nonetheless, they plan on selling a 5GHz H67 system.

P.S. it appears from the AT review (at least from the pics), that they were using an ES chip, which is consistent with the system builder's claim that OC with ES chips on H67 is impossible. Maybe all just a big misunderstanding. Sure would make sense given the pairing of the HD 3000 on the unlocked chips.

Cross fingers. REALLY AMAZING though that there could be such misinformation going around. Maybe these things are trivial to the real world beyond a bunch of computer geeks like us on a forum, but hard to believe that there also isnt some geek at Intel's marketing dept that would review major articles like Anandtech and say "hey wait a minute...."

I hope that is correct. It sounds very believable/likely. I think most early reviews would quite likely use ES chips, as Intel has them, but cannot sell them, so would put them to good use (the reviews mostly use hardware given to them for the review by the manufacture, for those few that don't know).

Here's proof: H67 CAN multiplier overclock the CPU! Unless they got the base clock to 121 while all other reviews cannot get past 110, most not past 105.

Ugh, this is all so confusing. First we hear there is no overclocking, and then we hear there is, but the ES chips couldn't. Considering the launch is only a few days away, I think it's important we get a definite answer on this.

I've also looked at some manuals that were available. asrock and gigabyte, and both had options to change CPU clock ratio. The only thing is uncertain how high does it go, could be artificially capped, maybe? Although i doubt it.

I think this is being downplayed big time by mobo makers, because it essentially erases the difference between mid and high end boards, but unlike intel they cannot make unpopular changes and piss everyone off, since its a commodity market, not a cpu duopoly.

We'll get a definite word once everyone buys enough of P67.

While I think some form of OC will be possible on H67, I do not think the manuals offer much assurance... I saw a BIOS video walkthrough for an Asus H67 board on youtube, and it surely had adjustable multiplier, but it appeared to max at the stock frequency (i.e. showed underclocking, but not OC). Waiting to hear back from the 'chap' that wrote the review (and hopefully from a few others) before buying a mobo. Heck, even zotac is advertising increased CPU TDP capability on their H67 ITX board... now why would they do that otherwise?

Officially - You can't, though H67 offers unlocked graphics multipliers. You need the P67 chipset for memory and processor multiplier change, regardless of the CPU. Oh, and "K" means unlocked processor multiplier. Even non-K CPUs have fully unlocked memory multiplier, and power limits.

Unofficially - Maybe. There has been cases where Intel has set a chipset limit but 3rd party manufacturers getting it working with chipsets that's not supposed to work(and I'm not talking about the heroic attempt ones, I mean everyone except Intel). Perhaps that's how Gigabyte's board supports overclocking with the H67 chipset. Unless that's a typo. Then you are screwed if you want overclocking and the graphics. Or wait for the Z68.

This.

I remember this same exact issue with Springdale(965) and Canterwood(975) motherboards on PAT technology.
MB manufacturers found a way to enable PAT technology for the 965 motherboards...Anyone who bought a 975 motherboard then was quite the moron or simply didn't do their research.

If this same thing happens with Sandy Bridge, I wouldn't be surprised.

 

[Hogan773]

Is there not someone in Australia or Malaysia or whatever with an H67 board and a K chip? We need to find that person. Some Aussie guy just posted pics of his system here, but its a P67......

1) LN2 claims to have an overclocked h67 for sale. zero specs. besides that its some gigabyte mobo.

2) PcPro UK reviews an overclocked h67. some specs.
Intel DH67BL:
"With just a standard Intel cooler, the i5-2500K remained stable as we turned Turbo Mode way up to 4.4GHz across all four cores."

3) H67 supports Turbo Boost. (does it not?)

turbo boost = multiplier change, no?

so DH67BL + 2500k can do 4.4ghz. sez PcPro.

this means:

1) best case scenario, fully unlocked: 100x44multi=4.4ghz

2) worst case scenario: limited unlocked: 105(max bclk)*41(max turbo+limited overclock multi)= 4.305ghz or thereabouts. even if bclk was pushed to 107 (how likely is that?) it would be 107x41 = 4.387 ghz.

judging from pcpro wording, looks like they just jacked up turbo multi. note how they mention it was the max they could do with a stock cooler, meaning we can go higher. 107 bclk is nearly the absolute max on sandy bridge it looks like. so to go higher we must be able to increase multiplier even higher. *** EDIT: 4.4ghz overclock seems to be impossible with limited overclock, as that would throttle back to 3.8ghz across all 4 cores, unless pcpro is doing it rong.

The only question now, is how high multi number can be selected on your particular motherboard.

DH67BL msrp is $107.

dougri, link for asus bios youtube video?thx

Their system is spec'd with a Gigabyte H67MA-UD2H board and expected OC to 4.7GHz. They've verified with their vendor (Gigabyte?) that the board does indeed support CPU OC, purportedly received a demo (at CES), and received a few samples to take back home. They seem like a pretty small outfit that has not yet tested their system in the spec'd configuration (testing on p67 to this point), but they seem confident they will indeed offer that system for sale at 4.7GHz WITH the ud2h mobo, FWIW.

 

[InternetUser]

Same guy, p67 video, he couldnt go higher than 34 multi in bios.

cpu ratio range says - 16 - 34
so thats not an indicator if you could overclock, looks like it just displays stock numbers and overclocking is always done via turbo.

makes sense with pcpro saying they adjusted the turbo.

pcpro responded and updated review:

"You chaps are right - the 2D benchmarks (including overclocked benchmarks) were indeed carried out on a P67 system, while the graphical ones used the H67 board as described. Thanks for catching that: I've corrected the text of the review."

Looking more and more like those wanting both will need to wait for Z68.

 

[PreferLinux]

Well, I haven't heard from Asus or Gigabyte yet, but I'll definitely post what they say when they do. We'll probably have to wait until Monday or so.

what about LN2 overclockers having that system for sale, and Intel PDF stating explicitly it unlocks overclocking features of K-series CPUs?

 

[coffeejunkee]

A dutch review of H67 mobo's stated that you can overclock the K series on this chipset. Nothing about ram oc-ing was mentioned.

What you can't do is use the extra turbo bins that are available on the normal chips. For that you need P67.

This would be in line with Intel saying you can use the overclock features of the unlocked chips.

I'm waiting for more solid proof though. And Z68 still seems better. If the rumors are true, that is.

And Intel says in their press information (in a note) that overclocking requires P67. In light of this, it may have been "you will have to do the overclocking with P67" rather than "overclocking requires P67". i.e. they forgot to say that retail CPUs will overclock with H67.

While I think some form of OC will be possible on H67, I do not think the manuals offer much assurance...

And the news items about that said it was for better overclocking/more overclocking headroom!

Link to review please. I would like to see that!

 

[Hogan773]

The mystery continues.

I guess by Sunday night or Monday morning, hopefully someone on these boards will have purchased an H67 and a K chip, and can tell us once and for all what happens!

 

[gevorg]

What about multiplier underclocking on H67? Is it possible with -K processors?

 

[PreferLinux]

What about underclocking with non-K processors? I expect both would work.

 

[InternetUser]

in another thread we have confirmed h67 turbo works with 2500 non-K. so at least we're not stuck with stock clocks.

 

[PreferLinux]

Well, that would be expected.

 

[InternetUser]

underclocking works ofc with any cpu. its called speedstep.
