MS5182 - doesn't recognicse increase in processor speed??

I have an MS5182  with an AMD K6-2 400. I recently swapped the processor for an AMD K6-2 500. I changed the DIP switch settings to change the multiplier from 4 to 5 but whenever it boots it still claims to be running at 400MHz.
Everything seems to work OK but I don't understand what it hasn't registered the increase in clock speed.  I am still using ver 1.1 of the Bios - is this providing some limit on CPU speed?
When I do get this sorted I'll have 320MB of Ram and a 500 MHz clock - well above the minimum for XP - so should I be able to upgrade from Windows 98 to XP OK?

Hi
Try clearing the cmos so that the bios can recognize your new processor.
You should be able to use xp even with the old processor. 
Here is a link to an newer bios that mentions the K6-3 450 but nothing about the K6-2.  You can also download a copy of the manual if it is needed.

  • Stupid question, is there anyway to increase the processor speed?

    i have been using my computer since november 2000, then i decided to get an ipod touch and so i had to install usb 2.0, a new HD, and some additional SDRAM. I know that conventionally there are limits to the amount of SDRAM that will get recognized, and stuff, but is there any way to increase the processor speed aka the MHZ of my computer that would be easier and more cost effective than just buying a new one?

    In addition to Tom's good advice, there's a chap on eBay who modifies CPUs for AGP models who goes by the eBay name of 'ijnuhb'. I've never used any of his mods, but he's been around a while and I've corresponded with him. Seems reliable.

  • Is Nokia 603 processor speed increased with Nokia ...

    Hello, I did the Nokia Belle FP1 update for my Nokia 603 phone. So far it seems ok, good improvements here and there. What I am wondering is whether the processor speed of 603 got increased from 1.0 GHz to 1.3 GHz like Nokia 700 and 701 phones.

    Yes,processor speed increased from 1 Ghz to 1.3 Ghz
    Though Nokia mentioned before the update that it will not get increase in processor speed.

  • Increase processor speed?

    Is it possible to increase/change the processor speed?  I have a Z61m 9450 38U.  I believe it's T2300E(1.66GHz).
    Thanks!
    Ian

    Just to add to ajkula66s post, the processor must be socket M. Also, the max FSB that the chipset can support is 667MHz. Here are some of your options... 
    Core Duo T2300, 2450, 2500, 2600, 2700
    Core 2 Duo T5500, T5600, T7200, T7400, T7600
    Saying that T7XXX series will work is partitally true. The following T7XXX series will not work as they are socket P...

  • Limiting processor speed to increase battery life.

    Does anyone know of a way to limit the processor speed to increase battery life while on battery? I know of some windows utilities that will allow you to scale back the processor, to say, 1 ghz or so, so as to get better battery life. Is there any way to do this with a macbook?
    Thanks,
    Zach

    Try CoolBook Controller out. It should do what you want.

  • New MacBook Air vs previous version- processor speed?

    I was going to exchange my < 2wk old MacBook Air for the newer version.  the new one has better battery life but it looks like smaller processor?  1.3 GHz vs the 1.8 that I have.  How much difference is this?

    500HMz is actually a pretty big difference... especially in this range.  Depending on your use though, it's entirely possible you would never notice.  Besides improved battery life, the new Air also has significantly better graphics performance (about a 40% increase).  What do you typically use your MacBook Air for?  If you use processor intensive applications, you may want to stay with your current model.  If you do things that involve graphics, the newer model might be a better option. 
    Basically... you might have one car that can go 200 miles per hour... and one that can go 150 miles per hour.  But maybe you only ever need to go up to 70 miles per hour.  Basically, they would both meet your needs as you'll never need the full power of either.  That's how you can look at the difference in the processor performance.  Just because one is lower, doesn't mean it will perform differently in your daily tasks.
    I personally would probably go with the newer model (especially since you're still within the 2 week return period).  The boost in graphics performance and the reduced energy use would outweigh the difference in processor speeds.

  • How can I check what the processor speed is

    We have an old white dome base iMac, running OSX 10.1  How can I check the processor speed - it is not available to choose in the 'about this Mac' dropdown?

    Turns out it is a mind blowing 40 MHz!
    Something read wrong. The slowest FP iMac was 700mHz.
    While in OSX, can you see if 10.1 has its own version of System Profiler? In newer OSX versions it's in Applications >Utilties.
    I jumped from OS9 to 10.2 so, like Eustace, can't remember what 10.1 has--or doesn't have.
    You can look dor the sticker/decal with the serial number. That usually gives the processor speed also:

    If you are running 10.6.8 you can download 10.9 from the App Store and install it with going through 10.7 and 10.8 first. 10.9 Mavericks is a free download in the App Store.
    10.9 Mavericks will require at least 2gb of RAM but really needs 4gb to run smoothly.
    As for third party programs see this list for compatibility with 10.9 http://roaringapps.com/apps:table
    Also Mavericks doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Mavericks.
    Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.

  • Variable Processor Speed

    All
    Was wondering if there is a way to change the processor speed or if it has something to do with how you change the batter settings. Ie performance vs battery life. Im running duo core temp and it shows that im running at 1.5GHz and not 2.0. I have a MB Black 2.0 512MB Ram (2GB in the mail)
    Thanks

    There have been a lot of discussions about memory allocation in the past, but briefly I touch on a few points. When an array is preallocated (initialized) to be a certain size LabVIEW is then able at compile time to set aside a certain amount of memory for that array. Then, if you are using the "replace array element" function within your loop the array isn't growing, just the values are being changed. If you are building the array in the loop, by appending to the existing array for instance, LabVIEW will continuously have to try and allocate memory space to the increasingly bigger array, sometimes having to move it to a whole new memory area. Additionally, and there are discussions of this in the other threads, if you branch the wires to different functions in the loop, LabVIEW will create copies of the initial array, compounding the whole problem, greatly effecting the execution speed, etc.  There have been a lot of discussions about the effects of using the various types of variables (e.g. locals and globals) and other efficiency impacts, for instance having an array of double connected to an indicator of single (or any other type mismatch) which is another thing that creates a copy of the data in memory. You can see that it wouldn't take too many of these to start having an impact on your programs speed. Do a search on this forum for memory usage, memory allocation, efficiency, etc. and you will see some of these discussions. One of the "nuggets" which initially deals with "Action Engines" discusses some of the causes and effects.  When you do search, check the date stamps, some of these might be a little old.

  • Odd problem relating to processor speed

    I'm hoping that there's some simple fix to this, because it's a simple problem in all honesty.
    Usually, when using my iBook I often switch between the "Highest" and "Reduced" processor speed options, depending on what I'm doing, where I am, etc; however, recently a problem has popped up. The speed of the system seems to be "stuck" in Reduced mode, regardless of whether I put it into "Automatic" or "Highest" again. I've checked the temperature, and sure enough - it doesn't even go above 50-55 degrees Celsius, whereas on "Highest" it would happily go up to 70-73 degrees Celsius if I was needing the processing power.
    I'm seeing formatting as an option, but would really rather not if I don't have to... Completely open to suggestions.

    Try resetting the PMU. Do that by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Wait 5 seconds and start the iBook.

  • Looking to buy new MacBook Pro for editing with Premiere/After Effects, but wondering about trade-off between Processor Speed and Graphics Card

    I'm a professional video editor (using Premiere and After Effects) looking to buy a new MacBook Pro and am deciding between two models. The slightly older model has a 2.8GHZ i7 (3rd generation) Quad Core processor with a 1GB SDRAM of NVIDIA GE FORCE GT 650M Graphics Card. Then newer model has a 2.3GHZ i7 (4th generation) Quad Core preocessor with 2GB SDRAM of NVIDIA GE FORCE 750M/Intel Iris Pro Graphics Card.
    Which makes the most difference (processor speed vs. graphics card) with editing with Premiere and After Effects?
    Any help/guidance would be greatly appreciated.
    Thanks!

    You recon? If he get's the 17", he would have up to 8x more RAM, 4 x more GPU,, and  a bit faster CPU;.
    2. Be aware of the advantages and disadvantages of extra RAM. Loading up the slot will make juggling multiple applications easier, like Photoshop, VLC, and Safari. However, more than 4gigs of RAM will make loading your MBP on startup twice as slow - at least a minute, probably longer. That's why a MBP user with extra RAM should sleep their machine nearly always when not in use, rather than powering off. 
    I did not know this, I just upgraded from 4gb to 8gb the other day. Have not noticed it being slower, but I don't often shut it down. It's nice to not even have to bother with ifreemem.
    3. Additional storage and RAM will maximize the basic capabilities of your MBP, but you won't be able to make a 2.3ghz machine any faster than it already is.
    SSD
    4. I still feel that your iMac will be faster than your prospective MBP. The only way to dramatically increase the speed would be the installation of a SSD drive (like the lauded OWC series). But they're not cheap.
    I don't want to rain on your parade, but want you to get a more realistic idea of your performance.
    I chose a macbook pro, 17" of cause. I use it for gaming. Yes a iMac is better for gaming. But, it's nice to be able to move around. Set up a man cave in the lounge 1 week, or in the bedroom, the next. But you fork out a lot more dosh for that luxury. And yes, not as much power as Poikkeus has said.

  • Processor speed.

    this may be kind of a silly question but, I have a KT3 Ultra MS-6380E , and on the specs, it say "Support 600MHz up to 2100+ MHz processor and higher".
    My first question is, how can I tell if my processor is either a standard athlon, rev A, or rev B?
    Second question is, can I use a rev B  Athlon XP on a KT3 Ultra MS-6380E since the processor speeds are around XP2400 to XP2800?

    while not officially supported by msi for 333 fsb processors, they will run..and yes, 2400 to 2600 xps will run on your mobo.
    i assume you are talking revision a or b tbred processors and how can you tell. here's everything you need to go, courtesy overclockers.com
    "How To Tell Them Apart"
    Edward Stroligo - 11/4/02, Updated 12/9/02
    We pointed out the other day that AMD will have two or (somewhat later) even three types of processors available for each speed bin: Palominos, TBredAs and TBredBs.
    To make your life easier, this will tell you how to tell them apart.
    The Approach
    There's two ways to buy a CPU, either over a website, or in person.
    Websites rarely list CPUs by stepping code. They will, however, often list CPUs on their webpages and provide their OPNs. That's the ordering number.
    So long as we have all these different type processors around, you should NOT order from any place that doesn't have the OPN listed along side the processor. If you do, you could well end up with a Palomino when you expected to get a TBred, or get a TBredA when you expected a TBredB. After all, the webpage said you were going to get an XP1800 or whatever, not that it was a Thoroughbred. If you want to send it back, expect to get hit with a restocking fee if the place has one.
    On the other hand, if you order from a reseller that shows the OPN on the webpage (and save the webpage) and the OPN on the webpage indicates a Thoroughbred, if you get a Palomino, you're protected. They didn't send you what you ordered, and you have proof of it.
    If you think I'm overly paranoid, well, I've been in this situation, and it works.
    Never accept a salesman's verbal word that you'll get the "right" one. Most places have their goods in warehouses, often miles and miles away. The salesperson couldn't find out even if he wanted to, and many salesmen will tell you anything to get the sale, then deny it later. Always get it in writing before you order, any reputable place will be happy to do that if it's possible.
    Website pages aren't always accurate. If there is any contradiction in the description of the item (i.e., the product is called .13 micron or "latest technology," but it has a Palomino OPN, either find another place, or email the reseller asking for written confirmation on just what it is they are selling.
    What I've said works fine with OEM chips; retail boxes are another story, especially if you're buying in person. I just haven't looked at these boxes lately. Could somebody who can look at some tell me what kind of identifiers are on the outside of the box that might let people identify what they're getting?
    Which Codes Mean What
    To make this easy, what you need to know is listed by processor speed.
    The OPN information is printed somewhere on every AMD CPU. For all Palominos, if you're looking at one, the OPN is the first code printed on the core of the CPU located in the middle of the processor. For all Thoroughbreds, the OPN the first code printed on the black area on one edge of the CPU.
    This information is based on current AMD datasheets, which are subject to change. We'll update as needed.
    There are three critical indicators in the OPN.
    AX1700DMT3C: Voltage
    AX1700DMT3C: Maximum temperature
    AX1700DMT3C: FSB Speed
    The following codes mean the following:
    Voltage
    L: 1.50V
    U: 1.60V
    K: 1.65V
    M: 1.75V
    All Palominos have default voltage of 1.75V, so all Palominos have voltage code of "M." TBredAs have a default range of 1.5-1.65V. TBredBs have a default range of 1.6V-1.65V.
    Maximum Temperature
    T: 90C
    V: 85C
    All AMD processors with a rating less than 2200+ have a maximum temperature of 90C, so they're all "Ts." Anything above that has a max temp of 85C, so they're all "Vs." FSB Speed
    C: 266MHz
    D: 333MHz
    Here's how these codes translate in real life with real chips:
    Update 12/10/02: A certain website did note a misspelling of the word "Thoroughbred," and I've corrected based on that. Thanks for catching it!
    1700+
    Palominos: If the website you're ordering from shows an order code of AX1700DMT3C, that's a Palomino.
    TBredA: If the website you're ordering from shows an order code of AXDA1700DLT3C, that's a Thoroughbred A.
    TBredB: If the website you're ordering from shows an order code of AXDA1700DUT3C, that's a Thoroughbred B.
    1800+
    Palominos: If the website you're ordering from shows an order code of AX1800DMT3C, that's a Palomino.
    TBredA: If the website you're ordering from shows an order code of AXDA1800DLT3C, that's a Thoroughbred A.
    TBredB: If the website you're ordering from shows an order code of AXDA1800DUT3C, that's a Thoroughbred B.
    1900+
    Palominos: If the website you're ordering from shows an order code of AX1900DMT3C, that's a Palomino.
    TBredA: If the website you're ordering from shows an order code of AXDA1900DLT3C, that's a Thoroughbred A.
    TBredB: If the website you're ordering from shows an order code of AXDA1900DUT3C, that's a Thoroughbred B.
    2000+
    Palominos: If the website you're ordering from shows an order code of AX2000DMT3C, that's a Palomino.
    TBredA: If the website you're ordering from shows an order code of AXDA2000DKT3C, that's a Thoroughbred A.
    TBredA/B: If the website you're ordering from shows an order code of AXDA2000DUT3C, that could be either a Thoroughbred A or Thoroughbred B. The only way to distinguish between the two is by the stepping code.
    All TBredAs have a stepping code which ends in "A," like "AIUGA." All TBredBs have a stepping code which ends in "B," like "AIUGB."
    P.S. There's two listed TBredA types in the AMD techdoc. One uses 1.6V, the other uses 1.65V. The TBredB is solely 1.6V.
    2100+
    Palominos: If the website you're ordering from shows an order code of AX2100DMT3C, that's a Palomino.
    TBredA/B: If the website you're ordering from shows an order code of AXDA2000DUT3C, that could be either a Thoroughbred A or Thoroughbred B.
    All TBredAs have a stepping code which ends in "A," like "AIUGA." All TBredBs have a stepping code which ends in "B," like "AIUGB."
    2200+
    TBredA: If the website you're ordering from shows an order code of AXDA2200DKV3C, that's a Thoroughbred A.
    TBredB: If the website you're ordering from shows an order code of AXDA2200DUV3C, that's a Thoroughbred B.
    2400+
    Sorry, no exciting choices here (yet). They're all TBredBs, and they'll have an order code of AXDA2400DKV3C.
    Yes, the DKV part is the same as for the 2200+. That's because a TBredA runs at 1.65V (that's what the "K" stands for) at 2200+. A TBredB runs at 1.6V (that's what the "U" stands for) at 2200+ and 1.65V at 2400+ and above. 2600+
    These are all TBredBs, too, but just in case "which one I am getting" is getting old, the 2600+ gives you a new, different challenge: What Speed Am I Getting? There will be two 2600+s, but they'll run at different speeds. Since the 333MHz bus helps performance, AMD figured (correctly) that a CPU running at a slightly lower speed and higher bus was the same as a CPU running at a higher speed and a lower bus.
    The 2600+, 266MHz version, will run at 2133MHz.
    The 2600+, 333MHz version, will run at 2083MHz.
    We'll no doubt see more situations like this as the number of 333MHz processors expands.
    The way you tell these apart by OPN is that the 266MHz processors will always have an OPN that ends in "C," while the 333MHz processors will always have an OPN that ends in "D."
    Next spring, we'll get more of the same when Bartons show up. You'll have Bartons and TBreds running at the same speed, too.
    Good luck.

  • Any way to increase BIS polling speeds?????

    Is there any way to increase the polling speed of the BIS for Earthlink? I have a mindspring email account (Earthlink) and it doesn't get pushed instantaneously to me. It usually just pulls a group of emails every 15 minutes or so. My other email account pushing to my BB Tour from my GoDaddy accounts come right away. Help anyone??

    No, there is not.
    A 15 (roughly speaking) cycle is routine on POP accounts. You can't change that. If the RIM servers find new mail, it reverts to 2 minute polling for a couple of cycles and should it find new mail yet again, retains that 2 minute polling cycle until which time it doesn't find new mail waiting, and then reverts back to the 15 minute cycle.

  • Increase Ipod Classic Speed Performance

    Yesterday, i just fooled around om my pc, and i found the option to defrag my ipod.
    so i searched on the web if it was safe, and they gave me the green light.
    so i just did it, and it is great!!! it really increased the speed of my ipod.
    it got the sensation of the speed increase by the updates back by just a simple defrag, which i didnt do on my ipods for 3 years.
    it seems that formatting and reloading works as well, but i havent tested that.
    about 30% of the coloured part was fragmented and all was solved, so only white and blue in the colour-scheme afterwards.
    maybe a tip to use against people whining for new speed increases in the firmware

    I just did this and it does increase the general speed of the iPod! It doesn't make coverflow much quicker except album artwork i think loads slightly quicker...
    It's also quicker when you select a song and getting the album artwork for it and when you go back from say games back to the home screen it's much quicker at changing the split screen...
