    May I know did anyone actually try this chip in a Mac Pro 5,1 (or 4,1 flashed 5,1)?

    Basiaclly, it's a x5600 series CPU but only 2 core avail with 4.4GHz. So, is this the fastest choice for the old Mac Pro if all I want is just the best single core performance?

    Everything I have read about the X5698 says that it is a 6 core CPU with 4 cores disabled so as to achieve the 4.4GHz rating.

    Yes, sorry for my poor English. That's exactly what I want to deliver.

    Anyway, do you know anyone successfully boot a cMP with this chip?

    Never seen anyone claim to and I honestly doubt any one has tried. It was a $10,000 OEM only CPU when it came out, and even now I doubt any one really wants to spend the money on them to try when the alternative upgrades are things like 3.2/3.33GHz 8 or 2.93GHz+ 12 cores. I know they sometimes go cheaply as they are pretty obscure so maybe it's worth a try?

    If you want such a thing then buy one CPU and try and boot it, you can probably sell it without losing anything but time if it won't boot.

    There wasn't a firmware update to get them to work on HPs systems AFAIK so should be fine. The only time I can recall a newer CPU from an existing line not working in the Mac Pro was the X5492.

    That's a highly rare and unlikely option for your mac pro.

    In the firmware flash forum, the only mention I saw was someone who could NOT get it to work, it would not boot.

    The xeons ending in odd (not 0 or 5) numbers like 5687, etc, I have seen discussed as being problematic. Known chips that work go up to the 5690.

    Yes, it's was super expensive, but now, the 2nd hand X5698 just cost a bit more than $1000. It's still very expensive if compare to the X5690, or any dual core old CPU. However, may be someone wiling to test it with this cost. And as you said, we can sell it if it won't work.

    Also, I know somebody here don't mind to use the ES chip. The X5698 ES only cost less than $500. For a non mission critical Mac Pro, may be a good fun to run at this super high speed and beat the maxed iMac on single core mission with just few hundred dollars.

    Thanks for the info. It seems no chance to make it work :(

    Not sure it would be worth making them work, either. For that price, an overclocked i7 would give you similar if not better single core performance. If single core is what you're concerned about, Xeon territory isn't the place for you. Sorry if this really didn't help answer your question, just another option here.

    The E5-1620 in the nMP likely beats it due to better architecture and turbo boost :/

    No worries, I am open to any discussion. However, I don't think there is anyway to OC a i7 in a cMP, right?

    Also, it's not that fair to compare a OC chip to a stock speed chip. If I OC a i7, I don't think that I can keep using the stock heat sink with the native inaudible fan setting.

    Anyway, I agree that the Xeon series is not design to achieve high single thread performance.

    It seems the i7 iMac still the king of the single core performance Mac (from GeekBench website).

    I meant the E5-1620 V2 would beat dual X5698s.
