Upgrading CPU's in a SunBlade 1000

    I don't mean simply pulling the assembly and sliding a new one in, I
    mean pulling the 750 cpu chip I have from the CPU module assembly and
    replacing with a 900 or 1.00gig. Possible, risky or daft?

    I belive they are pinless, how does that work then!

    I learned that Sun hardware is much heavyier but still much more
    vulnerable to mechanical misstreatment then any PC hardware. So i
    wouldn't do it. Don't you have a 900 Module ?

    And remember that the 900 USIII-Cu module will not work only the older
    900 USIII.

    Sun Hardware is almost impossible to upgrade as we all learned here :-(

  3. Hi,
    Replacing a CPU is a factory thing, nothing else.

    The fact that a "understand-less-than-they-think" shop can install CPU's
    on PC motherboard does not mean that they do it properly

    Most people I have meet which upgrads PC's and think they are
    PC-specialists have no background at all in Electronics, they just try,
    sometimes it works sometimes it fails.

  4. I'm not a hardware guy, but I believe the UltraSPARC processors used in
    the Blade 1000/2000 are like Intel's Slot 1 processors. The processor
    is matched to the (external) cache on the processor assembly, and they
    are not designed to be upgraded by removing the processor die itself.

    You would probably not find the processor die without the assembly. You
    can in any case not take another UltraSPARC processor (like the USIII+
    or the USIV) and mount it on the processor assembly. Using the same
    type of processor dies from systems (like the F15K) that use other
    processor assemblies might be feasible, but would require pretty deft
    soldering skills and probably specialised tools.
    The processor assemblies use a pressure-based connector that needs a
    special torque tool. All Blade 1000/2000 come with a suitable torque

  5. As usual, complete baloney. My Sun Blade 2000 came from Japan, and when
    I went to collect it the box was dropped over about 1m off a shelf. It
    booted without a problem. A HP business PC purchased from a local
    dealer had a loose CPU fan and video card when I took it out of its

    You have some anecdotic experiences with a couple of systems you bought
    from the cheapest possible secondary sources. Hardly a reason to
    generalise - and you've been told so many times.
    The 900Cu processor will work well in the Blade1000 - just that you
    cannot mix them with non-Cu processors, or mix speeds (like you could
    with the non-Cu versions of the UltraSPARC III). I believe that some
    very early revisions of the Blade 1000 motherboard can have issues with
    the Cu processors, but that's about it.
    Please don't use the word "all". I've successfully upgraded many Sun
    systems, and my experience is that they remain usable far longer than
    comparable PC equipment.

    Some systems (like the IPC and IPX of yonder years) were designed to be
    as small as possible, and hence were difficult to upgrade.

    The PCI based systems are quite upgradable, hardware-wise. Certainly
    no less so than cheap x86 based kit. For example, I cannot seem to find
    a Slot 1 CPU that will upgrade my 900MHz PIII system; the same system
    cannot take more than 384MB RAM (courtesy of no BIOS upgrade, and maybe
    even lacking traces on the motherboard). Intel and AMD for sure aren't
    going out of their respective ways to allow easy processor upgrades
    (care to enumerate all the different processor slots?), and the typical
    PC has not much scope for memory upgrades (how many 1999 vintage PCs do
    you know that take up to 4GB ECC RAM?).

    Please go and peddle your prejudices somewhere else.

    This does, however, assume that the replacement will be carried out by a
    Sun trained engineer who has the correct torque drivers etc and knows
    how to use them.

    I thought this thread was about replacing the CPU chip without replacing
    the whole module.

    CPU modules are FRUs. FRUs are those units that can be replaced in
    the field by a compentent technician. They're different to Customer
    replacable units, which ARE designbed to be replaced by end users.
    So, hot swappable disk and PSUs are CSU, but CPU modules and the like
    are FRUs.

    Can an end customer replace a FRU? Sure, provided they're skilled
    enough (I've replaced FRUs on numerous occassions, with no ill side
    effects), and/or have the right tools.
    Right, which is why they're FRUs rather than CRUs.

    As usual, complete baloney. My Sun Blade 2000 came from Japan, and when
    Sorry the CPU modules have extreme problems. I know a lot of persons
    who killed there CPU. Maybe you should talk about people who do this
    themself and don't have a 200 US$ per hour Engineer to do it for you.
    It's not only me i now many other people from other Sun forums.

    Again you completely miss the point but thats typical for somebody who
    don't need to pay for the equipement. A CPU upgrade that only allows
    20% upgrade (well or none if you already buy with a 900 module) does
    not mean anything. Was the CPU as the worst part of a system ever
    upgradeable to a reasonable speed ?

    Don't compare such a high cost machine with a PC system. This sucks, i
    can easily upgrade memory/cpu/mainboard for a few bucks. I expect more
    from a high end workstation like the Sparc Blade's. For a High End
    System i expect this just because for this price it has to work 5

  10. And this is different from AMD/Intel CPUs how? As soon as you think
    about upgrading it turns out that your socket 437/478/939/940/ CPUs
    are no longer made and that you might buy a few measly additional MHz
    while supplies last, but "upgrade" is generally out of the question.
    PCs are engineered to a single form factor, ATX boards with ATX
    casings; as such the whole picture is different. Sun just revs
    the whole thing (CPU/chassis/motherboard) whereas when others rev
    the whol thing they rev either the CPU or the motherboard.

    So why are the CPU modules listed as "Field Replaceable units" ?
    The OP didn't want to replace a bad FRU.
    He wanted to disassemble a working CPU module and replace the US III chip
    with an US IV!
    Not something even the most trained Sun engineer would be doing in the

    In many cases a knowledgeable owner of a machine could probably replace most
    Sun likely realizes this since many of the newer products have parts listed
    as a CRU instead of a FRU.

    Even on systems like a Sun Blade 1000 I've heard of people messing up the
    connectors on the system board by not seating the module correctly and or
    not using the correct torque tool and making it too tight.

  12. Hi,
    You are the one that miss the point.

    Nobody that uses a computer professionally in large scale upgrades it,
    you buy it, uses it for 3 years or so, then you replace it.

    You can not afford to upgrade it in half time since it gives so little
    back compared the cost(components+labour+reinstalling).

    You don't even upgrade a computers OS today, especially a PC. You buy it
    with XP use it, "Vista" will be on a new computer made for Vista when
    times come!

    Also, what you have missed is that many/all Suns systems are made for
    OEM and Telco and such so the motherboard and disks and so fits in a
    rackmount machine aswell. The WS is very often used for developing
    things that are to go to work on a rackmount server.

    And you don't upgrade a 111 rackmount servers in s server room or spread
    around the country, you replace them when times come.

    Upgrade and lifetime extensions is something that you do to ships.

    I have spent alot of money and time upgrading in the past, and one year
    later I still had to replace the WS's due to a new much better was out
    and needed.

    Michael Laajanen, Sep 4, 2006
  13. In that case the OP needs to be educated, preferably with a heavy LART.
    It would almost certainly not work anyway, the other chips on the module
    would also need to be changed.

    As the OP I was just asking! And I made no mention of US IV, I wanted to
    know if it was possible to install a 900mhz US III in place of a 750 US
    III on a Blade Module.

    Steve, Sep 4, 2006

    Rich Teer Guest

    And for the avoidance of doubt, the answer is no. You'll have to
    replace the whole 750 MHz module with a 900 MHz one.

    Interesting that you should say that. From Sun's website:

    "Sun's UltraSPARC IV+ processor provides a natural upgrade path for
    midrange and high-end UltraSPARC III and IV processor-based systems by
    enabling in-chassis upgrades."


    So who buys these midrange and high-end UltraSPARC III and IV systems
    and wants to upgrade them to US IV+?

    Josh McKee, Sep 4, 2006
  17. If you managed to do this without inflicting damage the CPU chip would
    still be clocked at 750 MHz.
    There are very good reasons for Sun's modular systems.
    Chris Newport, Sep 4, 2006
  18. HI,

    Could be for very huge servers that there are not so many of.

    I don't know how many really upgrade or trade the old ones in, it's alot
    of marketing around upgrades.

    Remember when HP announced HPPA tobe EOL, and sold the new HPPA systems
    which where upgradeable with Itanium modules, I wounder how many
    upgraded actually!

    Diskarrays are upgradable, any new bigger disks to buy for them,
    probably no ISP and others buy the a new arrays instead since the fans
    is about to brake and the PSU anyway!

    Just like the new mega x64 fileserver Sun announces by Andy, he said if
    a disk brakes, don't replace, disable it, keep running and replace the
    hole smack after a few years instead, much more economical.

    Why did you snip your words:

    "Nobody that uses a computer professionally in large scale upgrades it,
    you buy it, uses it for 3 years or so, then you replace it."

    Are very huge servers not used by professionals? Are they only used by
    the home hobbyist?

    As the OP I was just asking! And I made no mention of US IV, I wanted to
    Sorry about that.

    There was another thread where someone was asking about upgrading the CPUs
    on a Sun Blade 1000/2000 to US IV.

    Regardless to go to 900 MHz on a Sun Blade 1000 you would need to get a new
    CPU module.
    I'm not sure how much extra speed you would get from an extra 150 MHz.
    More memory would likely make a bigger jump.
    When I went from 256 MB of RAM to 1 GB on an Ultra 10 this was a major
    Likewise when I went from 1 GB of RAM on a Sun Blade 1000 to 4 GB it really
    jumped in performance.
