SB H67 mobos can't overclock? (even just multiplier OC?)

I just was told by a poster on the CPU forum that none of the H67 SandyBridge mobos will allow overclocking? Is this right?

I was planning on getting an H67 with a 2600k and using the integrated graphics. I'm not a gamer. Wanted ability to OC the CPU for video transcoding, etc. Also planned to buy the K series just to have the option to play around with OC in general.

With the K series all I need to do is change the CPU multiplier. Is it true with H67 one can't even do that? If so then I need to spend extra money on a GPU and "waste" the integrated graphics that comes with SB?

Seems odd. Or is this other poster mistaken (hopefully)? I realize most people don't have the mobos yet but wondered if anyone has knowledge.

Interesting link http://forums.anandtech.com/showthread.php?p=30957014

Video encoding using integrated GPU is never a good idea, I 'can' foresee issues with OC and onboard GPUs. Therefore, if you have this 'need' then clearly go the P67 with discrete GPU.

"Interesting link"?

Is there some rule that one can't ask the same question on two different websites?

No, it makes zip difference to me if you created a website or posted word-per-word on every forum. I see 80%+ of the questions posted here are duplicates -- one after another. 10~15 scenarios with different twists; actually to me it's getting boring.

My point was it's ALL hypothetical until someone actually tests-out OC + onboard GPU 1155. Further, as I clearly said 'if' rendering {encoding} is IMPORTANT then I would encourage you to go the dedicated {discrete} GPU route. Even the SAME series of 'GPU' the onboard is ALWAYS much slower and further costs you 'dedicated' system RAM.

Ok thanks (sorry you're getting bored on Tom's)

What do you think is an inexpensive but equivalent discrete GPU for a non-gamer that will be similar to the onboard capabilities of the SB?

In my "Everyday" a/k/a pseudo workstations I use the HD 5770 {XFX}, otherwise the GTX 460 {EVGA}. Both companies offer lifetime warranties.

I see. Let's hope I can OC on some version of an H67 board. I really don't want to spend a couple hundred bucks more for a GPU plus more expensive P67 mobo just to OC.

Crossing fingers. I just looked thru Gigabyte's website at the various H67 boards. Looks like they all list various "cloud OC" and "hot OC profiles" functions same as the P67 boards. They also have "PH67" variants that appear to use H67 chipset yet don't use the onboard graphics. Not sure what the benefit is of that. I didn't go thru all the P67 boards to compare that difference.

The HD 5770 isn't a couple hundred. I won't recommend GA MOBOs and in any case NEVER use a Utility to OC. There's NO good Utility for OC except MSI Afterburner - it's only good for a GPU OC.

Since the H67/P67 {1155} MOBOs aren't available I'd wait and see what several reviews come up with prior to purchase.

Yep, Speed = $!

Ok I'll have to learn what you mean by "don't use a utility". I guess my point is that if they have a utility program that apparently OCs, then I would think the bios itself would include some functionality. But who knows. Again all I need (I think, because I'm a noob) is a place to change the CPU multiplier from X to Y, and maybe bump up the voltage although I'd prefer to not even do that if I don't need to.

When the time comes, do it in the BIOS.

From Wikipedia:

Liquid Nitrogen Overclocking has shown instances of an Core i7-2600K processor operating at 4.5 GHz on a Gigabyte P67A-UD7 (no graphics) motherboard, and a Core i5-2500K processor operating at 4.2 GHz using a Gigabyte H67MA-UDH2 motherboard.

We don't know if the GPU was used or not. As the overclocking is via the multiplier, I don't see that the GPU would affect overclocking.

In early product releases, Intel said SB (processors, chipsets?) had a unified clock system that prevented overclocking, except for the "K" models which were unlocked.

Maybe a clever motherboard manufacturer can overcome that.

They've tried that, I think, and the standard methods were not working, but I think they will probably be successful eventually. The base clock is used for setting the frequencies of all the buses, I think, which means that the base clock cannot be changed much (i.e. less than 5%, probably more like <3%).

I NEVER suggested that that H67 couldn't be OC ; the question is "will the onboard" video work? I believe it will to a 'point' but what that point is who knows until you actually have one to 'play with' doing the OC. Since 'I' never use 'PC' MOBOs with onboard GPUs ... it not my thing.
December 25, 2010 2:55:17 PM

You're saying that by changing the CPU multiplier that could somehow impact the onboard GPU. I'm hoping that if Intel is offering K versions, and locking down the bus speed and everything else, that it will still work. This is not an old-school overclock with adjusting all the different levers and switches and timings...just a change in the multiplier. But as you said, time will tell.....

It just means I can't order an H67 mobo on Day 1....I need to get some field reports or confirmation that an OC is possible before I spring for the K version chip.

I do NOT know how far the Intel HD 200 can be pushed before corruption/failure.
