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.

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.

MBP 13" RAM Upgrade - different BUS speed

Dear all,
I am currently using MBP 13" Mid 2010, with 4GB RAM 1067Mhz, was thinking to upgrade to 8GB. My question is, instead of upgrading to 8GB with the same bus speed of 1067MHz, is it possible that this MBP supports 8GB 1333MHz? Other words, can this MBP supports bus speed of 1333MHz?
Thanks.

If it works you wont see any increase in speed. The operative words are "if it works." If your MBP supports 1067 then that's all you're going to get. Don't waste your time, effort and $.

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting?

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting on the computer, and how?

One possibility is that you may need to "Upgrade" your Cable /DSL Modem if you have an older unit. ISP's that provide your Internet service in recent years have been switching over from DOCSIS 2.1 version Modems to DOCSIS 3.0 version Modems, which handle the new higher data streaming speeds the ISP's are offering. I would suggest you call your ISP's Technical Support and inquire about this possibility.

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.

Scroll speed increases in InDesign CS4

I just installed InDesign CS4 on my Toshiba NB505 netbook running Windows 7 Starter. The scroll is driving me nuts. When I use my touchpad scroll, the first few lines scroll smoothly, but then the speed increases to jump several lines with every touch. The document I'm looking at is only one page, but I can't get to even the halfway point before it starts jumping. This appears to be the only program this happens in. Acrobat scrolls fine; my system mouse settings are fine. I'm hoping there's an option in InDesign I'm just missing.
Please help!

You'll do yourself a favor if you convert those TIFFs from 16-bit to 8-bit before opening them in InDesign. InDesign can only handle 8-bits of those file. I'm not sure how it handles 16-bit TIFFs but for 16-bit PSD files it reads the 8-bit composite saved with the file.
Your files will be considerably smaller, and will preview better.
The value of 16-bit is in making image adjustments BEFORE saving the file for other applications.

Portege M400 freezes, screen goes black and fan speed increase when moved

Can someone please help me?
I recently received the Portege M400 from a friend 4 days ago and reformatted to Windows XP Tablet edition.
All was going well until I wanted to move the laptop to my coffee table, but as soon as I move the laptop it freezes, the screen goes black and the fan speed increases dramatically!,
So far I have had no success in fixing this problem and I much appreciated is some one could help me!

Hi there,
I have the same laptop. Bought it from a friend also! That was a year ago. It was working perfectly till 6 months ago when I had it going 100% like yours. Screen freezes, fan speeds up and hangs up once it is moved. Recently, even if it doesnt move it hangs up also. I have tried many things like reinstalling drivers and Windows.....etc.
I dont think it is Windows problem or drivers problem, because if you run BIOS and try to move the laptop, it also hangs up!!
Tried updating the BIOS, also no benefit. I ended up opening the laptop and having a look to the motherboard (thinking that I could see something that I could fix!! But again, did not get any results.
I tried also disconnecting peripherals one by one to see whether I could spot the problem, I disconnected the battery, the hard disk, the optical drive, the wirelss modem (from inside), memory, and even the bluetooth, but could not spot the culprit.
I believe now that the problem is basically the motherboard (sort of wear and tear insulation problem) and it is beyond my humble expertise.
I am sure if I would contact TOSHIBA, they would not be of much benefit as I am a second hand user. And if I try to buy from them a main board, they will charge me hell of money.
I hope that this is helpful for you to avoid you wasting your time like me.
Please if you would come into any progress, let me know. Likewise, I would be happy to update you.

How much of a speed increase does a ssd give to a 2011 15 inch macbook pro

I am in the market for the new top end 15 inch macbook pro, I was wondering how much of a speed increase would I see overall. I would like to play world of warcraft, will I see a performance boost from a ssd? Thanks.

JoeyR is correct, the performance of a SSD drive is only on reads and writes
If you constantly exceed your RAM allocation, the pagination of excess memory needs to storage will be faster as well.
However a 7,200 RPM boot drive is pretty fast as well, at a lot lower $$ per GB than SSD and in a lot larger storage options.
7,200 RPM drives tend to use a bit more battery life than 5,400 RPM or SSD drives, if your on power most of the time then it's really not a issue.
Due to their limited writes, SSD drives are NOT being throughly erased using software designed for such purposes like on hard drives (Disk Utility), so any confidential information, sites visited, images and so forth can be recovered off of SSD drives.

Airport Extreme Upgrade Speed Increase???

1) We currently have an Airport Extreme version 7.6.4 in our home. What version of wireless is this running? How do we determine this?
2) How much speed will we gain if we upgrade to the newest version of the Airport Extreme which offers next-generation 802.11ac Wi-Fi technology (assuming that all of the portable devices in the house are upgraded as well to the newest technology)?
3) As part of this query, we have a Comcast modem that feeds straight into our current old Airport Extreme. To get any of the hoped for speed increases, would we have to do anything with this Comcast/Xfinity cable modem?
Sorry these are such basic questions that likely reflect my poor understanding of this technology. Any guidance would be greatly appreciated!

Last question first.
3) As part of this query, we have a Comcast modem that feeds straight into our current old Airport Extreme. To get any of the hoped for speed increases, would we have to do anything with this Comcast/Xfinity cable modem?
The Internet connection speed on your network will not improve. That speed is limited by your modem and the plan that you have with your provider.
Right now, the current AirPort Extreme that you have is capable of far greater speeds than your service provider can ever hope to deliver, so a new AirPort Extreme will not provide any improvement in terms of Internet performance.
) How much speed will we gain if we upgrade to the newest version of the Airport Extreme which offers next-generation 802.11ac Wi-Fi technology (assuming that all of the portable devices in the house are upgraded as well to the newest technology)?
The wireless speed capability will double to triple over what you have now, but these higher speeds will only be realized when you have both an 802.11ac router and 802.11ac capable devices.
There are no 802.11ac capable iPhones or iPads, so you will pick up faster speeds on a new MacBook Air, MacBook Pro, or iMac, etc.
The faster speeds will only help you if you are copying data from one computer to another or making backups of one device to another.
As mentioned previously, your Internet connection speeds will remain the same that they are now.
We currently have an Airport Extreme version 7.6.4 in our home. What version of wireless is this running? How do we determine this?
Please look on the bottom of the AirPort Extreme to locate the model number. It will start with an "A" followed by four numbers. Example.....A1143......A1301.....A1354.....A1408.
Post back with the model number, and we will tell you a bit more about the product.

Kernel patch for more CPU families offers measurable speed increases

I wanted to show folks a pretty nice patch that allows one more options when compiling a kernel for CPU families. Complete list included at the bottom of this post. I tested it using three different x86_64 machines running a generic x86-64 kernel and an otherwise identical kernel running with the optimized gcc options.
Conclusion: There are small but real speed increases using a make endpoint to building with this patch.
Details:
1) Three test machines: Intel Xeon X3360, Intel i7-2620M, Intel Core i7-3660K.
2) All ran the make benchmark (linked below) 35 times while booted into a 'generic' kernel. Then all ran the same make benchmark 35 times after booting into an optimized kernel. Below are the optimizations chosen for each machine.
2a) X3360 = core2
2b) i7-2620M = corei7-avx
2c) i7-3660K = core-avx-i
3) Analyzed resulting distributions for statistical significance via ANOVA plots that clearly show statistically significant albeit small differences.
Discussion
1) All the assumptions for ANOVA are met:
*Data are normally distributed as show in the normal quantile plots.
*The population variances are fairly equal (Levene and Barlett tests).
2) The ANOVA plots clearly show significance.
*Pair-wise analysis by Tukey-Kramer shows significance at the 0.05 level for all CPUs compared.
Below are the differences in median values:
core2 +87.5 ms
corei7-avx +79.7 ms
core-avx-i +257.2 ms

I agree, your CPU, in practice, is really either idle or loaded.
In my case (AMD 965, 4 freq steps) the processor is at lowest freq for about 90 - 95% of a time, and at highest for 5 - 10%. The 2 intermediate are used for about 0.1% of a time.
My guess would be that intermediate ones are only used for smooth transition from lowest to highest. So they really are hardware dependent...

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?
John Fenn

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.....
Your fellow eMac User,
Matthew Knice

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

Safari 5.0.2 great speed increase

Does anyone else see a huge speed increase? The slow load times seem corrected. This is the best version in a very very long time.

Agreed, although I would not call the speed increase 'huge' - all versions of Safari 4 and 5 have loaded pages in less than a second for me.

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.

Will I get a speed increase with Infinity?

I currently have the standard broadband unlimited and get about 3-4MB download speed.
Is upgrading to infinity likely to give me any speed increases?
Matt

Hi canhefixit,
With ADSL (ADSLMax, ADSL2/2+) broadband the BB signals run from your local exchange to your property all the way via a copper phone line. This is why the further away you live from your local exchange the slower your broadband will be.
BT Infinity is BT Retail's brandname for fibre broadband.
Depending on what Openreach fibre infrastructure has been rolled out in your area will depend on what speeds you are likely to get.
The main fibre technology that is being rolled out around the UK is FTTC (Fibre To The Cabinet) fibre technology.
FTTC allows currently allows speed of upto 80mbps dependent on what Infinity package you are on and how far away you live from the FTTC Dslam cabinet.
FTTC works by installing a Dslam cabinet that is linked to your existing pcp. The new FTTC cabinet is connected to the local exchange via a fibre cable and then your property is connected to the cabinets via the existing copper phone line.
So for FTTC the external layout would be (simplified)
Local exchange >> Fibre Optic Cable >> FTTC Dslam Cabinet and existing PCP >> Existing Copper phone line >> Property
For FTTC the speed is dependent on how long your copper phone line is from your property to the cabinet. The further away you are from the cabinet the slower the FTTC broadband will be. Line quality also play a part.
FTTP (Fibre to the Premises) fibre broadband technology has also been rolled out in certain areas in the UK. This allows speed of upto 330mbps and requires a Fibre Optic cable to run all the way from a FTTP enabled exchange to your property.
To find out what Fibre broadband speed you maybe able to get enter your BT landline number into http://dslchecker.bt.com/adsl
In the grid there will be WBC FTTC ( if available to your property) and will be given an estimated speed.
It will also tell you what exchange you are connected to and what pcp (cabinet) you are on.
If you don't have a BT recognised phone line then you can try using your address by going to http://dslchecker.bt.com/adsl/ADSLChecker.AddressOutput It won't be as accurate as using the phone number but should be accurate enough.
Hope that helps and makes sense.
Cheers
