Penryn MBP bus speed?

Does anyone know if the 17 inch MBP/s FSB has been bumped up to 1066 yet if you get a 2.6?
The 15 inch on the spec page said 800 fsb but I could not find it on the 17 inch MBP.

My wife stole my MBP within two weeks of its purchase and now her original lappy(a pc hp that she said was too heavy after she hammered me to buy it is losing its DC jack for the third time. Based on its current rate of demise I have between 3 weeks to two months of use. That will put me in the serious "need to buy" market between June and July. I have already been looking hard at refurbs to. Problem there is, after my education discount, the price advantage drops to only 300 bucks and apple care is 239 instead of 339 so those prices get too close to brand new. All she is demanding this time is a new iphone so that is a decent green light. I know the montevina will be released soon so that makes me real nervous as this is the same time of year I bought the core duo a month or two before the core2duo came out.

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 $.

New (Penryn) MBP instantly ejects DVD -R DL media

I recently bought a 2,4 GHz Penryn MBP with a MATSHITA DVD-R UJ-867 (Firmware: HA13) optical drive. Profiler states it CAN burn DVD-Write: -R, >>>>-R DL<<<<, -RW, +R, +R DL, +RW media.
However when I insert a brand new FujiFilm -R DL (I tried 3 of them) - the drive spins up then down and then ejects the DVD without any error message whatsoever. I have extensively searched the Forums, however I can not find my specifig problem answered anywhere.
Any ideas?
Thanks in avance,
d00t

i have the same machine, (early 2k8 mbp) and i can burn dvds and cdrs but NOT dvd-dual layers! It craps out usually at the verification process with this message (in console)

I have YET to be able to burn any Dual layer disks at all - at least 9 bricked in a row so far.
So, i called applecare, got the machine sent in to be "fixed". They had it for TEN days, and then returned it to me with a "we couldnt duplicate the problem" message! I then tried to burn a dual layer yet again getting a wonderful coaster... According to the console it doesnt appear they tried using dual layers when they tested.... But anyway, zapping P-RAM, making a new user, the usual stuff didnt fix it. Tried 3 different companies disks too. Does the same in Disk Utility, and Toast. No dually layered love... period.
I havent called back in, because im afraid id be tempted to reach through the phone and strangle and innocent... i think ill try a clean install next, because i cant afford to go another ten days without it.

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.

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

Lost MultiTouch on Penryn MBP

Greetings -
Two month old 2.5 Penryn MBP. Everything fine. Apogee Duet causing a few odd crashes out of Logic Pro and iTunes that were never there before.
Now three-finger swipe does not work. Funny how used to it I've become! Everything is enabled in preferences. It just flat-out doesn't work anymore.
I did a search and saw posts recommending deleteing Preference /plist files as well as pulling the battery and AC and holding down keys and power button for 10 seconds, etc. Their problem wasn't the same as mine and I view the plist files kind of in the same light as Windows Registry and figured I'd ask before randomly deleting them!
Thanks to all. 95% of my questions are resolved using the search function under these discussions. In fact just an hour ago I "fixed" an iChat problem plauging my wife's MacBook for the past year or so (needed to change the port to 443 from the default!). Gotta love it!

RE: +view the plist files kind of in the same light as Windows Registry+
Not exactly. Similar in intent - storage of settings/options information. But, .plist files are more 'innocuous' that the Registry - an advantage of this is that corruption to one of these files will normally only affect a single application, whereas corruption of one of the Registry hives can have system-wide effects.
You can safely delete a .plist file, and all that will do is force the application to create a fresh one the next time it's launched (this includes the Finder). Any custom preferences you had set will be 'lost' with the return to the default .plist file. So, it's safe to delete the appropriate .plist files from ~/Library/Preferences.
Hope this helps...

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.

Uneven Brightness (new 17" Hi-Res Glossy Penryn MBP)

Finally got the new Penryn MBP I ordered the day they came out, and it seems to be working fine, but the only "issue" I see is the back light seems uneven. Its only noticeable on a white/light color solid background. Just wondering how common this is. I had to wait almost 3 weeks to get it, so I assume the wait would be just as long or longer to get it fixed. Just a bit of a let down, especially after having to wait 3 weeks for it.

Obviously, quality control is something Apple feels it can afford to do without, as they are usually quick to replace these defective products at the counter.
This statement is blatantly false. Granted lemons do slip through the cracks, and sometimes it is impossible to make a system crackproof when dealing with so many products. Just a single 128 MB RAM board has one billion parts. That's as many as the Saturn V Rocket! Apple's sales of notebooks have gone through the roof, and if you do get something in warranty that obviously needs repair, do use the warranty to take care of it.
Opened a second 2.4 15 Inch Penryn and found the LED on this one had a gradient that darkened on the far right. They
Disassembling the machine as you have done basically exposes the machine to static electricity and other problems, and frequently is noticeable because of the difficulty of reassembly. I would let the warranty people take care of it, or the store return policy take care of it.
Apple's quality still is the best in the industry, if you read Consumer Reports.
So don't let the preponderance of issues reported on this board make you think they all have issues. Quite the contrary many without problems never have reason to report here.

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.

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.
