Intel plans to deliberately limit Sandy Bridge overclocking - Hardware & Software

[url]http://www.bit-tech.net/news/hardware/2010/07/22/intel-to-limit-sandy-bridge-overclocking/1[/url] [quote]Information provided by Intel in its own presentations about its upcoming mainstream LGA1155 Sandy Bridge CPUs appears to confirm the company has designed the CPUs to deliberately limit overclocking. A video to HKEPC and posted on YouTube (see from 2mins onwards) confirms the fact that only a 2-3 per cent OC via Base Clock adjustments will be possible. This is because Intel has tied the speed of every bus (USB, SATA, PCI, PCI-E, CPU cores, Uncore, memory etc) to a single internal clock generator issuing the basic 100MHz Base Clock. This clock gen is integrated into the P67 motherboard chipset and transmits the clock signal to the CPU via the DMI bus. This means there's no need for an external clock generator that used to allow completely separate control of all the individual hardware. When you're overclocking, you want to be able to push certain frequencies, such as the Base Clock and memory clock, but leave others, such as SATA, completely stable as they're very sensitive to adjustment. Current motherboards allow multiple bus speeds because external clock generators are programmable via the BIOS. According to one Taiwanese motherboard company, on a Sandy Bridge system, the fact that all the busses are linked means that turning up the Base Clock by just 5MHz caused the USB to fail and SATA bus to corrupt.[/quote] Even happier I went AMD in my last build now :D

nice steal off of apex

I really don't think you'd need to overclock with a Sandy Bridge proc anyway.

Nice going Intel. Thank god I'm going with AMD for my next build. $280 for a core 2 quad? Go fuck yourselves.

If that's true, then trust me, the motherboard manufacturer WILL find a way to circumvent that for their "enthusiasts" boards. Also neat fanboyism, makes your post look 100% legit and unbiased /sarcasm.

I mean hell with the i7's and the i5's out, that is still pretty fucking expensive for a 3 year old processor. And no, I am not a fanboy. I have never used AMD in my life.

Good way to keep people from saying "Dude don't buy the ****2, just buy the ****1 and overclock and it actually will perform better." Makes sense from Intel's standpoint, want a performance processor? Pay the price they want to charge.

AMD rules. :smile: Admit it Ajacks.

[editline]08:50PM[/editline] And hell, a Q9550 is enough if your PC is mainly for gaming (and if you don't Crossfire/SLI graphic cards).

well it looks like if i'm going to buy the new motherboards I'm going to have to cut a pin off my i5,

[QUOTE=>VLN<;23543244]Nice going Intel. Thank god I'm going with AMD for my next build. $280 for a core 2 quad? Go fuck yourselves.[/QUOTE] it performs better than every phenom 2 there is, so they kind of can price it however they want

Didn't they untie the clock of all devices on the motherboard in, like, 1995? :downs:

And then I have to buy a new motherboard? And a new case? And new ram? And a new power supply? Nope. :downs:

So why are you complaining about the price of Quad core processors? You have a very good processor without buying a new motherboard and RAM. [editline]11:25PM[/editline] That's great for the buck

[QUOTE=>VLN<;23548355]And then I have to buy a new motherboard? And a new case? And new ram? And a new power supply? Nope. :downs:[/QUOTE] new case? new PSU? what are you talking about the difference between an i5 750 and Q9650 covers a large portion of the MoBo/RAM cost anyway

[QUOTE=>VLN<;23548355]And then I have to buy a new motherboard? And a new case? And new ram? And a new power supply? Nope. :downs:[/QUOTE] yeah and you also have to buy new RAM and a new motherboard to switch to AMD :downs: idiot buy a Q9650 for $330, have i7 performance without paying >$500, and like I already said, they can price those quads like that because there isn't anything better [editline]05:39PM[/editline] [QUOTE=reapaninja;23548526]new case? new PSU? what are you talking about the difference between an i5 750 and Q9650 covers a large portion of the MoBo/RAM cost anyway[/QUOTE] maybe if you buy the cheapest P55 motherboard you can find and the cheapest RAM, otherwise the price gap is pretty big

[QUOTE=Odellus;23548678]maybe if you buy the cheapest P55 motherboard you can find and the cheapest RAM, otherwise the price gap is pretty big[/QUOTE] £100-120 easily gets you decent 4GB DDR3 or a half decent mobo

Just overclocking the Q9550 is the way to do. But yay, I agreed mostly what you say about their performance compared to i5/i7.

[QUOTE=reapaninja;23548924]£100-120 easily gets you decent 4GB DDR3 or a half decent mobo[/QUOTE] + CPU so you're looking at 300-340 GBP? and on Scan the Q9650 is 263 GBP. so it may be the case for the UK/Europe, but not the US [editline]05:53PM[/editline] [QUOTE=ADT;23548969]Q9650 is pretty expensive compared to Q9550, and they are the "same" processors.

My personal situation is slightly different because I have to afford a new 775 motherboard (because my father had chosen an Micro-ATX G31/G41 motherboard like a idiot), a new PSU (to remplace my generic one) and case. But yeah, your point is not stupid when we have to think about it. [editline]12:00AM[/editline] Except if you have to buy a new graphic card in the same time, you can save at least some money for buying the Q9550 instead of Q9650. [editline]12:02AM[/editline] I just wish my dad could help me about some components, but he is bloody greedy when it comes about that. I don't even know if he could help me for buying a 55€ motherboard.

Why buy a Q9550? There is no need for that speed. A Q8400 or Q6600 overclocked are great oc'ed and save a lot of money. I was personally waiting for sandy bridge to reach 8 cores then ditch my Q6600, but with this crap I guess my next processor will be an Amd piece. And vln you are a retard for using the utterly stupid complaint that core 2 quads cost a lot. Of course they do, when idiots like you stay on old architectures and buy new parts they kick supply and demand into effect and the price for old parts go up.

Wow, that's a lot of BS. I'm on a Phenom II X4 955 now and happy with it =)

There's not even a noticeable difference between AMD and Intel for a normal PC user. AMD just happens to be cheaper most times.

goddamnit I had specifically planned on going sandy bridge and overclocking it in my next upgrade [editline]04:39AM[/editline] If this is true, it will kill Intel in the enthusiast market.

We'll just see how Bulldozer is.
