Yea I had forgot that, you can raise the multi now which is alot better, and almost won't limit it at all as you can just keep pumping the volts on the cpu without touching other values, so the memory speed is even less relevant
And yes you should still be able to OC to 4+ghz as the current SBs have an unlocked multiplier, each multiplier bump increases it by 100mhz, these are said to hit 4.4 ghz on stock volts and cooler:
"Since we’re relying on multiplier adjustment alone for overclocking, your motherboard and memory actually matter less for overclocking with Sandy Bridge than they did with P55. On both P67 and H67, memory ratios are fully unlocked so you can independently set memory speed and CPU speed. Even the GPU ratios are fully unlocked on all platforms and fully independent from everything else."
Yeah me too. I wish someone could shed some light on the matter. It's the same revision p67 chip, obviously because they all just came out. It should support the same memory as the other makers boards.
While other boards do show higher speed RAM as usable in their boards, mine (an ASUS P8P67 Pro) also states that anything over 1600Mhz will be run as 1600Mhz. It states this is a characteristic of the CPU. Therefore, IMO, it is pointless to use mega speed RAM. Intel claims the CPU is designed for up to 1333Mhz. There is nothing much wrong with this fact although many posters on this site seem to only care about speed and not stability. You would be hard pressed to see the difference in real world actual use, except in test programs.
Read this review carefully and you'll see what I mean:
By the DDR standarts the fastest official ddr3 speed is 1333mhz, if you look at other motherboard specs they list anything from 1600 and above as OC, even though there are 2400+ modules, it's like getting a factory OCed video card.
It doesn't make alot of difference anyways, just spend a few dollars more and go for a different brand if you want to use 1600, only Intel knows why they decided not to include 1600 support.
Because the SB CPU has a SPEC 'Supported Memory" which is limited to 1333 MHz, and Intel's BOXDP67BG also ADDS 1600 MHz 'supported' speed. Intel is not going to out/over spec their own CPUs. Oddly, many Intel P67 MOBO won't support the unlocked 'K' CPUs either - i.e. won't allow for OC'ing of their own unlocked CPU.
That's a corporate decision, and my first assumption is an Anti-Trust policy. So I severely doubt that Intel will be publishing something like that openly.
1333...vs...2133 MHz RAM with SB http://www.bit-tech.net/hardware/memory/2011/01/11/the-... read the entire article; in short RAM > 1333 MHz will see only a modest gain. Next, you need to factor-in errors and you end up scratching you head -- is 1333 MHz $50 worth the 2133 $150 with SB??!!
