2100 ram vs. 2700 ram (or higher) - FSB speeds matching with CPU

Question regarding 2100 RAM vs. 2700 RAM or even higher...
My system specs are below. Would replacing my 2100 RAM with 2700 RAM make any difference in system performance? I was under the impression that your CPU FSB basically worked in coordination with your RAMs.
So, say my CPU is a 266fsb (set at 133 in the bios), and my 2100 ram is also 266fsb...
If i upgraded to 2700 ram, wouldn't my ram still run at 266fsb because the CPU is still running at that speed?
Hopefully my question is clear enough. I see people recommending upgrading to 2700 ram or even 3200 ram, but I didn't think it could run any faster unless your CPU FSB was matched up with the RAMs FSB.

If you buy anything buy PC3200 (DDR400) since PC2700 isn't any cheaper.
But you are correct, you will see little to no differance in preformance since the CPU's FSB is already matched.
The board can run the FSB at 266 and the RAM at 400, but it gives little in preformance terms for the above reason.
There is a slight preformance agvantage since the extra bandwidth might be usefull for DMA operations (HDD, AGP writes etc..) but not very noticable in a PC.

Kernel_task high cpu usage, high fan speed, and low cpu tempterature

Hi,
I've noticed that a lot of people have been having trouble with the kernel_task process, but I couldn't quite find a situation similar to mine (most seem temperature related).
Here is the situation (15' MBP, mid-2010):
- on boot (while the apple logo is shown), the fans speed suddenly jumps, and stays there, even if the computer has been off for a while.
- boot takes a little over a minute, which is considerably slower than what I was used to before today
- when finally started-up, the activity monitors shows kernel_task using between 160-180% of the CPU!
- temperatures are shown to be around 30C, except for the mem controller at 40C (still very low temp), but the fan speed is arround 6000rpm for both fans.
- this happened out of nowhere, as I woke the mpb from sleep this morning.
Since then I've tried:
- multiple reboots
- install all updates
- uninstall flash player (some people where having trouble with that)
- empty the system cache with Onyx (reported as a cause of slow boot)
- reset PRAM
- reset SMC
- put some ice packs under the mpb to cool things even further!
And so far, nothing has worked! I've had this laptop for 1 year, and nothing had ever failed. I upgraded to lion a few weeks ago, and everything had been working fine since the upgrade. This really happened out of nowhere, and none of the many forums I have read could offer a solution, and cals to apple support do not seem to yield better results (though I scheduled a call with them at 9am this morning, we'll see).
Has anyone had a similar set of problems?
I appreciate any help or advice you may have!
Thanks!

I have the same issue (2.66 2010 MBP Hi-Res Anti Glare.)
I took it to Apple Store Covent Garden, JUST within warranty.
18 days later my machine has a new Main Logic borad, heat sensors, top case, palm rest. etc.
I turned it on.
The fans kicked in. All processors at 50%, big ole kernal task.
I took it back, geniuses rest SMC and tested it under load and it was fine.
weirdly it failed diagnostics at first but then seemed fine
I came home. Fans kicked in...
I took it back. Diagnostics failed heat sensors again
Replaced logic board and heats sensors again, but more carefully this time just in case, tested again.
I took it home. FANS FANS FANS.
Last time I was in the store I was told my machine was fine and had been thoroughly tested.
In mac store, no fans.
I erased hard drive and clean installed Lion
FANS
I replaced hard drive with OCZ SSD, clean LION.
Fans
Software update
SMC
PRAM
permissions
Onyx complete clean/maintenace
FANS/CPU
switched back to Snow Leopard SSD
PRAM SMC ONYX etc.
FANS/CPU
replaced RAM, memtest-ed. fine, FANS
gonna try again but up to nearly 2 months of all my spare time trying to shut this thing up so I can sell it.

KT6 lsr high fsb boot up problem fixed

Luckily I don't have the "20°C" reboot problem, but I did have a problem booting up at high fsb speeds. It seems that the motherboard must remain energized while not in use in order to boot up at 200+ fsb speeds for me. If I switch off the main power to my surge protector I can't boot up, and I have to clear the cmos and boot at 166 fsb. Then I can move up to 200 mhz from there. I was really getting annoyed because I like all the features of the kt6 lsr, but a MB that can't boot is useless. I forget who mentioned this in the "kt6 lsr reboot" thread but thanks

Bas mentioned bootup problems after long power downs (i.e. unplugging power supply). Thanks for the idea

Upgrading RAM and Flash Storage for higher capacity

If I purchase a MacBook Pro with Retina Display with 8GB or RAM and 256GB Flash Drive, can I later upgrade the RAM and Flash Drive for higher capacity?

Just to clarify...
If I were to purchase a "regular" MacBook Pro (non-"retina", DVD drive, FireWire port, etc.) and seek aftermarket options for...
(1: replacing the main RAM with 16 gigabytes of RAM (I understand that the newest "regular" MBP is limited to a BTO option of only 8 GB.)
and
(2: replacing the hard drive with a larger-capacity aftermarket Solid State Drive, preferably one with a capacity of either 768 gigabytes or 1 terabyte.
Do such aftermarket options exist for the newest "regular" MacBook Pro? Can this model handle 16 GB of RAM? If there are aftermarket kits available, who installs them?

PC2-5300 Ram in a PowerBook G4 High Res?

Hi, All.
I am dying on a vine here. My 17" PowerBook started locking up on me about a month ago and then finally died altogether. I had 2GB of Kingston RAM in it (running smooth for over 2 years). This is the 10/2005 model which takes DDR2 RAM. I took my computer to the Genius Bar, after changing the HD and trying different RAM configurations. We sent it off to have the Logic Board tested, but it was sent back saying the 3rd party RAM was the issue. I tried TechWorks Ram and Samsung RAM, both from OWC, but still got the panics and lock up problems. I took it back to Apple/Genius Bar where the tech spent 2 days running tests and again confirmed my PB worked fine with Apple memory. This, of course, was all done free of charge and I do appreciate that.
So, the tech said he used newer memory, the PC2-5300 RAM that is coming in the new MacBooks. I also read that this memory would work in my PowerBook since it also used DDR2 memory. So, I'm on my 4th type of RAM now, some Hynix PC2-5300 that came out of a new MacBook Pro and when I turn on the computer, the power light blinks 2 or 3 times and that's it. (I have no sound, another issue which hasn't been addressed).
Is there something I need to do to get the computer to recognize this memory, or was I misinformed about it being backward compatible with my PowerBook. I really hate to spend another penny on memory, when it seems like my problem is Logic Board related. However, Apple will not test the logic board until I have Apple RAM in the machine. My guess is they will want the PC2-4200 memory that came with it originally.
Any help would be greatly appreciated. This is my 4th PowerBook and 10th Mac machine I've owned in my lifetime and I have never had this much trouble. I'm going on a month now without resolution.
Thanks in advance.
Derek

Welcome to the Apple discussions.
Sorry to hear about the memory issues. Apple sources memory from Crucial/Micron, Samsung, and Hynix, that I'm aware of. So when they say they want 'Apple' memory in there, they are talking one of those brands.
On the Crucial website they say that memory is designed to be backwards compatible, noting, however, that faster memory will operate at the slower speed the computer is designed for. Apple did have a note for the original mac mini about using PC3200 memory in place of the spec'd PC2700 memory.
That said .... our Powerbooks are sensitive souls when it comes to memory. Memory which has met Apple's written specs has often not worked, because the Apple architecture uses bus slewing, which is tough on memory (a google search on 'mac memory bus slewing' will turn up the Apple developers documentation that talks about this).
If the memory is the right memory, your Powerbook should fire right up. Personally, I'd recommend Crucial memory ... they guarantee that their memory will work when chosen from the memory selector on their web site at http://www.crucial.com .

What is better high fsb or tight memory timmings?

for all the overclock masters out there what do you think is better high fsb or tight memory timmings?

You should really read the sticky posts as they hold the answers.
This one in particular as it relates very closely to youyr setup.
https://forum-en.msi.com/index.php?topic=74799.0
FSB is way more important to OC'ing any modern Athlon. In fact as the memory controller resides within the CPU now unlike in past rigs too tight of timings will certainly have a negative impact on how far you can OC. The reason is that as you increase the FSB your also increasing the RAM clocks. RAM will usually fail an OC before a CPU will. So you really should read that topic and learn more about how these rigs OC now days and what you will need to know to be successful at this.

[AMD] problems errors ram with cpu vcore change on k7n2 delta2 platinum

hello
i'm a french new owner of k7n2 delta2 platinum and i got something strange.
I have 2*512 PC3200 cas3 of kingston value ram with voltage 1.75 instead of 1.6v running in dual CAS 2.5/3/3/8 at FSB 195 like the cpu : 2500xp barton.
With occt and memtest86+ i'm stable with a CPU vcore at 1.725.After 195 the computer starts but not really stable. So i put the cpu vcore at 1.75 to put higher fsb and then i get thousands RAM errors with memtest(even if i stay fsb 195). i tried with cas 3/3/3/11 and it was worst. On the bios B5 i tried with different settings : agressive, optimal, 1/1, auto, manual, patch ddr or not...and always the same. My PSU is 450w noname and i've 4 HD 1player 1 burner & a geforce 5200 o/c 10%.
Of course i'm happy to reach 195 but i feel disapointed to be stop with this problem of vcore/ram because i have not problem of temperature with a silent boost for cpu(52°c maxi), 3 fans for the box(35°c maxi) and copper memory heat spreaders for ram.
thanks for your answer

the thing to check is the vdimm voltage for the ram ... i'm pretty sure it should be around 2.6 volts .. try upping it one step
vcore is the voltage to the cpu and doesn't affect the ram

"...So i put the cpu vcore at 1.75 to put higher fsb and then i get thousands RAM errors with memtest..." I would say it's not the v. core but the CPU o/c. that gives that errors, as it make not sence to increase v.core only for itself.
Oh yes it does
The CPU and memory work hand-in-hand. If one is out of sync it can cause the other to start spitting out errors.
You are overclocking and that more of a scientific art, not an exact science.
Components react differently to an entire list of variables, especially the CPU/memory.
What you are trying to do requires trail and error testing however I agree the Kingston memory is holding you back at this point with the clock you are pushing
I would go for the most stable FSB settings that allow Dynamic Overclock to be enabled to SERGEANT before I would go for ultra High FSB because you will peak the system at its highest performance curve when you need the boost, and I would bet money that peak would be higher than any strait FSB over-clock you can hit stable.
Psychologically allot of people think their systems are not running the highest performance it can unless they set the system up at the highest FSB/multiplier and that is simply not true with dynamic overclocking enabled and correctly tuned with the rest of the components.

Can my 600MHz P-3, 256MB Ram handle a data acquisition of more than 1kHz with waveform chart support?

please suggest tools for acquiring high speed 8 analog channel data.
can my 600MHz P-3, 256MB Ram handle a data acquisition of more than 1kHz with waveform chart support?

Arun,
I have performed data acquisition on a computer with lower specs than the one you described, at rates greater than 1 kHz. I don't quite understand the "waveform chart support" portion of your question, but if you are asking if it is possible to plot the acquired data on a Waveform Chart in LabVIEW, this should not be a problem.
If you have more specific questions, let me know.

Does the MacBook Pro Intel Core 2 duo (2,4ghz - 4gb RAM) match with an audio dj mixer Pioneer DDJ SR

I bought a Audi DJ mixer Pioneer DDJ SR and i want to know if it matches with a Macbook pro core 2 Duo, 2,4 GHZ, 4gb RAM, 250gb DDR?
If not, then can i make it match by adding 4gb RAM or changind DDR to SSD, or others?
Thanks for your help.
(I am french and my English is not so good, so please let me know if my question is not clear)

Hi Rick,
Given that the MBP has a 4200RPM HD in it now, any 5400 or 7200 is likely to yield a significant speed increase during operations requiring HD access.
If it is a 15" MBP, make sure you get a 9.5mm high, 2.5 inch SATA HD. If it's a 17", a 12.5mm high HD will fit.
I don't believe any brand of current HDs is significantly better/worse than the others. That said, I think Seagate is at a low ebb of quality right now. I think Hitachi is at the top. WD blacks seem to be consistently reliable. Without question, others will have different opinions (it's like asking if a Toyota or Ford or Honda, etc. is best). I really like the idea of Seagate's hybrid drive, but there is a real mixed bag of reviews on it. It's first gen, and there are issues to be worked out/improved upon. Check out newegg for 200+ user reviews.
AFA 5400 vs 7200, all other things being equal (rarely the case) the faster drive is likely to give better response, but don't expect night and day difference. All other things being equal, it's also likely to run hotter, reduce run time on battery, and increase vibration. There's also a bit of a cost premium.
Whichever you end up with, remember to backup, backup, and backup (I highly recommend a clone and Time Machine).
The odds are you/she will be happier with any of the 5400s or 7200s over the current 4200, and a new drive should easily help you/her get another year or more out of the MBP. Good luck with the decision.

The difference between regular ram and "apple ram" from 3rd parties

So I made a previous post on the Macrumors forums regarding whether the RAM issues in the Unibody MacBook have been resolved or not: http://forums.macrumors.com/showthread.php?t=692653
It seems that most people who bought OCZ ram have had no issues what so ever. I am located in Canada so a store like CanadaComputers is great for me because I can go pick it up instead of having it delivered and pay shipping costs (as opposed to Newegg.ca). On their website, they have two modules with similar specs expect one is found in the Apple ram section and the other is in the regular ram.
Apple Ram (OCZ)
http://canadacomputers.com/index.php...80&cid=RAM.188
Regular Ram (OCZ)
http://canadacomputers.com/index.php...id=RAM.187.778
When comparing the specs, the only difference I can see is that the CL on the Apple ram is 7-7-7-20. The CL on the regular ram is CL 8-8-8-27.
The price difference between the two is $57! OCZ's website confirms that one is made specifically for Apple Notebooks and the other is just regular.
Can anyone explain what CL is and whether it is something that needs to be taken into consideration. Thanks.

That only needs to be taken into consideration if you're using applications which are very demanding about performance, which aren't intended for usage by home users. Click here for more information.

5300 RAM showing up as 3200 in Quad, any experience with this problem?

Hello, just received a 2 gig kit for my G5 Quad (2 - 1 gig sticks from Crucial). System Profiler shows it's speed at 3200, lower than the original 512 RAM which is 4200. Crucial says it will only reach 4200, but why is the new RAM showing up at 3200? Tried removing original RAM and only using the new, same speed displayed - 3200.
Has anyone had any experience with this oddity? Any idea if the RAM is not performing or the Mac is not giving accurate speed data?
Thanks, Steve

Memory identified as PC2600 in MDD
Symptom
Apple Hardware Test identifies the computer's memory as "PC2600" rather than "PC2700".
Products affected
* Power Mac G4 (Mirrored Drive Doors)
* Apple Hardware Test version 1.2.6
Solution
There is nothing wrong with your computer's memory. This issue is addressed in Apple Hardware Test 1.2.7. If you have version 1.2.6 and are experiencing this issue, contact AppleCare for a replacement disc.
Apple is aware of that. It first showed up in 10.3.0 and has been there ever since. The issue with the above DDR2 is I think different and unique.
With the MDD, Apple used Micron in the system I got, and I added Crucial. Both show up as '2600.'

Want to upgrade from 4mg RAM to 8mg RAM MacBook Pro mid 2012

I want to upgrade my MacBook Pro (13" mid 2012, 2.5GHz, Intel Core i5) from 4mg RAM to 8mg RAM. Running Mavericks. Any suggestions on which brand name RAM I should consider?
Do I need to go to an Apple Store to get my RAM put in (quite far for me) or is it okay to go to a place like Future Shop or Best Buy? Should I attempt it myself?
I found this thread:
http://support.apple.com/kb/ht1270

2 sticks is the norm. Crutial is recommened because it is known to work properly, as well as having support. I have read of instances of problems with other suppliers. Try pricing it from Apple.

T420 won't boot with 2x4GB RAM (two identical RAM)

Hi all,
I am experiencing a weird issue that I'm hoping you'll be able to help me with.
My T420 came with 1x4GB of ram (underneath the keyboard) and I wanted to upgrade to 2x4GB RAM so I bought exactly the same RAM again.
Both RAMs work fine by themselves, in the bay under the keyboard as well as in the bay underneath the laptop. Both RAM were tested individually in both RAM slots. The laptop works just fine with either of the RAM individually in either of the RAM slots.
BUT if I put them both in at the same time, the T420 won't boot. It switches on (screen stays black) and instantly switches back off. Without pushing any button, the T420 will then switch itself on again about 3-5 seconds later. This process is repeated indefinitely. I don't even get to see the ThinkPad security screen where you can access BIOS. I switched the RAM around in the slots but this didn't resolve the issue either.
I have never had anything like that before. Does anyone have an idea on how to solve this problem?
Thank you very much in advance.
Regards
Lippasti

Has seriously no one ever had this issue? There must be a solution to this since I can rule out that either one of the RAM or the RAM slots is damages since each RAM works fine in each slot separately. I'm only experiencing this issue if I put them in simultaniously.
Is there possibly any BIOS settings which I need to adjust prior to installing the second RAM?
Not that I think it matters since I can't even boot it to the Windows screen but here are some specs. I am using a Kingston 512GB SSD and the other specs are:
Here's the RAM I am using.

Is there a noticeable difference from a 2gb ram to 8gb ram on 2.3ghz mac mini?

Just asking if it is worth upgrading to 8gb on my 2.3ghz mac mini with 2gb of ram in it.

Ram is so darn cheep. I would always opt for more ram up to 8 GB just in case I need it someday.
