    its either cheap paste or the gap,but whatever it is cutting the lid and replacing the paste with liquid pro improves things 1000%

    That makes two of us... I will be upgrading, but I'm looking at mid-autumn.

    I've even loaded it up with Prime95 and Linx not once did it use turbo boost :(

    Also none of the manufactured systems allow you to play with any system voltages of frequencies. I'd be curious to know what would constitute enabling turbo mode.

    The Xeon E5520 is a 45nm, Nehalem-era socket 1366 processor that does have Turbo boost, running at 2.26GHz - 2.53GHz:

    ARK | Intel® Xeon® Processor E5520 (8M Cache, 2.26 GHz, 5.86 GT/s Intel® QPI)

    For Turbo to be enabled, that option must be enabled, but it's also possible that Turbo is disabled by other means, or simply impossible to enable in the BIOS, regardless of the BIOS setting. The boost increase is typical for this generation of CPUs (0.26GHz), so not a big difference. I imagine that board's BIOS will follow the Turbo time limit specs exactly, and would be active for a very short time.

    IMO, CPU-Z is not good for checking Turbo boost, since it reports one CPU frequency, while Turbo is applied on a core and thread basis.

    I'm we aware of the CPU spec, I was just answering your question. and yes you can see when turbo is applied as CPU-Z reports the CPU speed in real time and these systems do not turbo a single multiplier but all at the same time.

    you had asked a question regarding turbo on a Xeon, so I gave you an answer.

    That is, Ivy Bridge architecture, 22nm Xeon processors, which may use conventional TIM as the consumer Ivy Bridge processors do. Nehalem processors have solder between the die and IHS, and do not become as hot as IB CPUs when over clocked.

    I was also discussing the the operation of unlocked 'K' processors, whose multipliers are used to OC, and are not controlled by the standard rules that apply to Turbo (Turbo 2.0 in this case.) I was not referring to Xeon's, since they are not unlocked. The single CPU frequency display of CPU-Z when used with SB and IB CPUs seems to be that of core 0, but who knows. When I compare CPU-Z to a multiple core frequency display (HWiNFO64), CPU-Z is sluggish, its update rate seems very low, and seems to retain the highest read value.

    Hmm, I could swear that the cores of my i7-930 can change the multiplier on an individual core basis, they certainly do when SpeedStep is active. But Xeons may work differently.

    Ya know, I have seen that too, but I can't recall where. What is your source of that information?

    Many of the all in one PCs that are appear to be large monitors already use mobile processors and SODIMMs. If Broadwell will not be BGA only, then what is the concern about? Is it all just bad information and rumors? Or is the line between mobile and desktop CPUs becoming less well defined, since mobile CPUs are being used in non-mobile PCs.

    I also just thought, what about the enterprise market? Would they be fine with a non-replaceable CPU system? I have no idea how often enterprise systems replace processors, if they do, and why. Why would Intel go to BGA only in the consumer market, but still produce socketed processors for the enterprise market only?

    it on Wikipedia,its going to be split into three teirs,and only the small form factor and laptops will be bga,the desktop will carry on as normal socket

    Well so much for that rumor, we should of known better. Good to see that it will use the same socket 1150 as Haswell.

    There is another aspect of Haswell that is different than earlier CPUs that has not been described very well, and could cause changes in mother boards. That is, to quote from the Wikipedia page on Haswell:

    Fully integrated voltage regulator, thereby moving a component from the motherboard onto the CPU

    Specifically, Haswell will have only two two voltage inputs, Vccin for logic and Vddq for DRAM. Everything that uses power in Haswell will be derived from the single Vccin rail, compared with up to five independent rails on IB or SB, not including DRAM voltage. The CPU voltage adjustments we have now should be the same with Haswell, according to Intel.

    That ought to simplify mother boards a bit, but let's hope the voltage controls in the UEFI/BIOS will work as expected, or will we be faced with some changes?
