Bus Speed on LimeBook

This Lime iBook is slowing down more and more as I add stuff to it. I'm wondering how much bus speed has to do with it, accessing and all that. I perform all the regular maintenance and use macJanitor also. Is it just a consequence of older technology and slow processor speeds? Mine is the SE with 466 mhz CPU.

RichardIf you are using more and more of your Hard Disk space the system is limited on the amount of virtual memory it can use. It is advisable to leave at least 10% of your hard disk free. I assume you are using Mac OS 9 (this was what would have been supplied with your Lime iBook originally. The hard disk could also do with de-fragmenting now and again under OS 9. (Although you shouldn't do this if you do have OS X installed.) You can tell the bus speed of a mac by looking in the System Profiler. The Processor speed is also a good hint. Your processor is 466. 466/66.67 = 7. This is the multiplier (usually an integer). If you go to the Control Panel and Energy Saver there is an option check box which can reduce the multiplier to 5.5 ... 5.5x 66.67 = 366MHz - this saves battery power - only available on the 466 iBooks and Powerbooks. Many of the overclocking mods for Macs involve changing the multipier - but this involves serious hardcore soldering so it's not an option unless Apple builds in the option.
To get your iBook to go fast I recommend you:
Up your RAM to the maximum (576Mb)
Upgrade the Hard Disk or purchase a Firewire External Drive.
My other tip would be to not buy brand new software - it invariably requires more processing power (as it is aimed at today's machines). Look out for the same (geniune) software but older versions on eBay.

G60-519WM motherboard bus speed, CPU support list

I was given this laptop in 12/2010. It of course has the celeron 900 in it with an 800 MHz fsb. My question is what bus speeds does the mobo support and where can I find a list of supported CPUs. The only semi-reliable info I found suggested upgrading the cpu with a t9600 that has a 1066 MHz fsb.

Hi:
Below is the link to the Maintenance & Service Guide for your notebook.
http://h10032.www1.hp.com/ctg/Manual/c02985882.pdf
Supported processors are listed in Chapter 1, starting on page 1-1.

How can I determine Bus Speed

Hi all
Dumb question #2.
The beast is a G4 MDD with dual 450MHz chips and the model number is M5183 and the machine number as per System Profiler is 406. Serial number is SG03402HK5W
Got all that.
I need to determine Bus Speed so I can buy the proper Ram Cards for this machine. It was supplies from the eBay seller with PC133 chips in there and surprisingly enough it runs 9.2.1 just fine.
How can I determine whether my machine is a 100MHz or 133MHz.
I suspect my Machine is not an MMD but a Gigabit Ethernet with dual 450 processors. Is this correct?

You can find all the G4 specs here to identify your machine and get the RAM specs and bus speed.

Changing the system bus speed?

Hello,
I have an overclocked 700MHz (now 900MHz) eMac, with a 100MHz system bus speed, and I am wondering, is the only way of messing with the processor speed overclocking it? And if you CAN change the bus speed, will it make the eMac feel any faster? Since the processor is at 900MHz, I would like the bus speed to be around 750-850MHz. Is that even possible? I've tried googling this kinda thing, but all I get is how to overclock it. (I got that part already, I just want to know if I can change the system bus speed too.)
Regards.....

I'm thinking that, with two months of viewing, it either isn't possible or offeres too much risk of turning the computer into an expensive doorstop.
The Beige G3's bus speed was controlled by jumpers, relatively easy to tweak. Newer Macs tend to be hardwired

Thanks a lot.

Hi.
It's problem found same bus on T5140 becouse this server have different architecture.

can i update to snow leopard?? and how? im having a hard time its my first mac.   I need to to create documents, Im trying to avoid buying a new computer.

You cannot upgrade to snow leopard. Snow leopard was the first of os x to drop support for the motorola ppc processors. The latest you could possibly run would be leopard.
Hope it helps,

G4 Bus Speed

I'm running a Power Mac G4 (Mirrored Drive Doors) and was wondering if there's any way to update the bus speed? currently I've got 167 MHz.
presumably there would be no point in updating my processor from 1.25 GHz with 167 bus speed?
cheers,
Liam

is it all pretty much governed by bus speed?
Of course, bus speed is a limiting factor, though processor speed, cache size/location of cache are equally as, or more, important. RAM controller speed, and CAS rating of memory chips, amount of memory, GPU speed, and VRAM clock also contribute to system performance/limitations.
Faster processor means faster handling of data, resulting in faster system response.
Dual processors allow for additional data threads to be processed simultaneously, resulting in faster system performance.
A larger cache, closer to the processor (L2 vs. L3) allows for a greater amount of data to be buffered (temporary storage) within easy reach of the processor, resulting in faster system performance.
A slow bus can benefit from a faster processor, this is a given. A larger L2 and/or L3 cache also increases performance, this is proven.
How much of an improvement all of this makes, depends on the overall configuration of a system, and from where the upgrading began. In the case of a 400mhz system going to a dual 1.8ghz processor, the difference is around 400-500% improvement. Depending on the process/application, though, the bus will, in fact cause the processor to slow down, while waiting for the rest of the system to "catch up", if you will...
In the case of a 1.25ghz machine moving to a dual 1.42. with the exception of multi-tasking, the overall improvement in performance will be slight, due to the slight increase in processor speed. But, with multi-tasking, video, graphics intensive work, etc., a dual processor, even of the same speed, will greatly improve the performance by virtue of the multi processing ability of the dual. This is why current systems have moved to multiple multi-core processors. Here lies the potential for greatly improved performance and speed.
But, again, all system components need to be optimized for optimal performance. Back to the bus issue, in the end, the slower (relatively speaking) bus of a G4 will be the ultimate limiting factor of a
machines performance.
Let us not forget, though, the Sawtooth was once considered a "Super Computer" and exports were initially seen as a national security issue. The MDD is a further refined/enhanced machine, and has good life left in it, even in todays "speed is everything" mentality.
do you reckon upgrading the CPU will make much difference
Keeping the above discussion in mind, browse the database at XBench, and you can see how various processors compare in performance in the MDD.
I will say that moving from a single to a dual processor, of higher speed, can be seen as a worthwhile upgrade.

G4 bus speed increase

I am having compatibility glitches between my G4 733 and 5th gen iPod video. i was told my bus speed was not fast enough for a clean iTunes upload. It gets stuck on certain tunes and stops loading. Can I increase the bus speed (133) to be more correct for the iPod?
Also does anyone know if there is a plan to upgrade from usb to firewire?

Hi, Paul!
I upload music to a 5G, 60GB iPod repeatedly without issue, using a B&W G3 with USB 1.1, so I'm very skeptical about the bus speed being insufficient to handle a "clean" iTunes upload, as you referred to it. In fact, I did the complete initial iPod upload of a 16.2GB iTunes Library on the G3 via a USB 1.1 interface with no issues.
It gets stuck on certain tunes and stops loading.
"Certain" songs? If you mean that specific songs fail to load, I think that you likely have a totally different issue than one of transfer speed, regardless of what you may have been advised elsewhere.
Gary
ps: I haven't loaded any movies to the iPod from the G3, instead using my QS G4 where they reside, but I will do this as another "test" for you, if you would like.

Clocking bus speed

I know that on the beige desktop 266mhz apple computers you can clock the bus speed from 66mhz to above 80mhz, so how exactley do I go about this?

This page has the jumper settings and some discussion:
http://www.xlr8yourmac.com/G3_OC/tims.html
If your RAM is only PC-66, running the bus faster than 66 MHz runs it faster than its specified and tested speed. This may make it flaky. It is very difficult to decide what the problem is when your memory is flaky.
If you are considering expanding your memory, using the faster memory from the Blue & White G3, which is otherwise identical, may put your mind at ease about memory problems.
Overclocking can sometimes improve performance 5, 10, or 15 percent. It can also break things, so it is not something to try on the Mac you need every day. It can make things unreliable. If you really need a big speedup, you should think about a newer old Mac.
If you are starting with a 266, you can buy cast-off processors from faster G3 Macs pretty cheaply. a 300 MHz with a bigger cache can often be had on eBay for US$35 or less.

Can I upgrade my 2006 iMac4,1 with Intel Core Duo with 1.5GB memory, 667MHz Bus Speed, 2GHz processor from 10.4.11 to the newer OS systems? I've been told my machine is now "vintage" or obsolete...

Can I upgrade my 2006 iMac 4,1 with Intel Core Duo w/1/5GB memory, 667GHz Bus Speed, 2GHz Processor Speed to the newer OS systems?
I have been told my machine is now "vintage or obsolete" and can't be upgraded to the newest OS software.

The maximum OS for that iMac is 10.6.8.

2 Issues: Low Bus Speed and Visable Hairline on LCD

I noticed on the system properties window that after the P8400 @ 2.26Ghz it has the bus speed at 791Mhz. I thought it is suppose to be at 1033Mhz. Is there anyway to check if it's a settings issue or if the processor is defective?
Also on the LCD display there seems to be a 2 cm long hairline slightly arcing from near the bottom right edge. I though it to be a scratch but upon closer inspection the mark appears to be behind the surface. I'm not sure how that could have happened but I'm curious as to what it is.
I know the care instructions say not to pick up the laptop from the screen, but I do pick it up sideways (lid closed, pick up as you would a tray). Is that considered a nad idea?
Thanks for any help you guys can provide.

if the LCD is not damaged by you, and the hairline is due to some manufacturing defect, then you can get it repaired under warranty by Lenovo.

Fcp - ram speed, bus speed, and 64 bit processing

how much do these (ram speed, bus speed, and 64 bit processing) specs play a role in fcp's performance? I hear conflicting opinions about it's utilization of the 64 bit processor(s). some say yes some say no. is ram speed from one rev to the next that much different, particularly in the last two G5's? Or, is the amount of ram and the processor type the most important considerations in optimizing fcp performance? thanks for your help!

SD/SDI card is to bring in video material in formats other than DV. If all you will ever work in is DV or HDV, firewire only is fine. If you want to work with non-DV formats and without expansion slots, you need to look into something like the AJA io to do your conversion and bring it down firewire. This solution has its own potential problems when the device and the hard drives are on the same bus.
You need a second drive just for media. On the Powermac you simply add a second internal drive. This is not possible on the iMac - an external firewire drive is the only option. This by itself is not an issue. Most people who do this with any seriousness end up adding a series of external hard drives to deal with the mass of media.
The limiting factor is that you only have one firewire bus (all macs have only one firewire bus) and if you run into problems with the camera (or VTR or AJA io) & hard drives not cooperating on one bus, you have no option to fix it. On the iMac, you have no option to add in a card to create a second firewire bus in the system.
So yes, the people at the store are correct. You can make the iMac work (with an external firewire drive). However, if you run into problems, you have severely limited options to mediate them. What I was trying to suggest is some things work better. An analogy might be, If I need to drive nails, the handle of a screwdriver can be made to work, but I should not be surprised if it does it badly and breaks when pushed hard.
good luck.

Bus Speed and Ram Speed Question..thanks

I have recently purchased my first mac! I purchased a refurb but I noticed that the one I purchased has bus speed of 800mhz and the ram has 667mhz. (I did get a 320g hard drive vs a 250g and a 256mb graphics card vs a 128mb) The other one has bus speed of 1066mhz and ram speed has 800mhz. Am I going to notice a difference in the bus/ram speed difference or just stay with the one I purchased?
thanks

I don't think you will notice a difference. Other system factors (such as video card, system CPU clock speed, amount of RAM installed, speed of hard drive, etc.) will most likely overwhelm any noticeable difference cause by the slower bus speed.
If the price of the refurb was good, you should keep it. I have an online Apple Store refurb myself, and although I know that the latest iMacs are a bit faster, I don't see how that extra speed will be of great benefit to me. I'm much happier with the money I saved on the refurb compared to a new iMac.

What is the bus speed of the SCXI 1001 chassis?

I'm trying to locate the bus speed for the SCXI 1001 chassis for use in accelerometer data acq.

Normally for a 12 bit DAQ device the maximum sampling rate of a SCXI chassis is 333 kS/s. There are several factors that affect this such as number of channels, DAQ device, number of chassis, etc. Here is a link that contains some additional information.
