GPU RAM (the more the better?)

What effect will having more RAM on a GPU card have for MPE (or even AE)? I noticed that EVGA makes a 1.5GB and a 3GB version of the GTX580. Other then the obvious price difference, will it improve performance? and in what way?

Only in cases where you use large images in pixel dimension you may notice a difference, because if all the VRAM is used, PR falls back to software rendering. Look here: http://blogs.adobe.com/premiereprotraining/2011/02/cuda-mercury-playback-engine-and-adobe- premiere-pro.html

New News about slots? RAM: Is more really better?

Hi,
Ok, two questions in one post but if I can save one tree,... it's worth it...
Has there be any new consensus regarding filling one's RAM slots versus leaving 2 empty?
I've done my own limited testing in PS4 and AE4 and it seems to make no difference at all. What apps benefit from leaving two slots empty, taking advantage of the hyper-threading, I believe?
And when is RAM too much RAM, as in not needed? Due to a recent bout of madness I went from 16gb to 32 in my Mac. The difference? Awfully subtle, if one at all. Even having the preference in AE4 of putting more memory to individual processors, being able to increase it, has had little noticeable effect in that app. Am I happy I have the RAM, yes. For what I paid for it, no. Does it really boost performance? Not as much as one might hope.
Caveat emptor?

I looked through more of my bookmarks for dual vs triple. Tests on other motherboards, different OS, are likely going to show different results, but....
The reply in this thread is of interest:
http://www.tomshardware.com/forum/245839-30-triple-channel-memory
*Everest Ultimate Conclusion* Everest shows virtually no difference in dual vs triple channel mode with clockspeeds being the deciding factor. you will also notice the latency scores show much lower results than Sandra was reporting,( with latency Lower is better) again due to the different way of rating the performance. We were surprised to see such little difference in Everest after the virtual shut out in Sandra.
This is exactly why we like to use more than one kind of test to evaluate products we test and also helps to illustrate that not all performance tweaks will render a positive result, depending on what you are doing sometimes it will render a similar result.

For us, the real issue was how much of the memory bandwidth bottleneck prior Mac Pro the move to DDR3 offer customers. Intel's own Core i7 X58 for PC builders comes with just 4 DDR3 DIMM slots, not 3, and not 6 as most (all) the other desktop boards come equipped with (does Intel know something?).
It is also interesting to see the enormous advances CPUs have made in the virtualization area:
•The latest Xeon 55xx of early 2009 is about 4.2 times faster than the best 3.7GHz dual-core Xeons of early 2006. Moving from the 3-4 year old dual-core servers towards the newest quad-core Opterons/Xeons will improve the total performance of your server by about 3 to 4 times. http://it.anandtech.com/IT/showdoc.aspx?i=3567&p=12
Intel (and Apple) wanted to move beyond the cost, heat, latency of using Fully-Buffered ECC which can use 10-15W per DIMM - Apple needed theirs to come with very large heat spreaders to keep the heat produced under control.
http://www.anandtech.com/weblog/showpost.aspx?i=603
There may be more trouble shuffling data between two CPUs with just 6 or 8 DIMMs. I'd like to see a single cpu with 3 x 4GB configuration setup. Or 6 x 2GB, also 12GB. And then compare to 4 x 4GB. Get the dual cpu out of the equation.
Future I think means 2nd generation Nehalem 2010, with the move to shrink to 32nm.

What Exactly are the Benefits of More GPU RAM for PP, AE, PS ?

What benefit is there to having, say 4gb GPU RAM over 2gb ?
I have read numerous conflicting, and perhaps misguided, claims regarding when/why one would rather have a graphics card with more than 2gb RAM.
Does this impact effects render, multiple monitor resolution, CUDA, Mercury Playback Engine performance, other areas, etc. and how?
Thanks for your response.
A Ajar

2GB of video ram is more than enough for the Hardware MPE engine and 1080 media with effects. Essentially the greater the ram space on the video card the greater ram caching available for the Cuda acceleration to buffer data ready for GPU processing. The Application memory management ie caching profiles though effect this based on each codec and resolution ie data per frame. However along with this you have to have enough system ram to create the buffers used to cache the data down to the GPU ram since that data shadows down for GPU processing and then back again for final encoding. This means that not configuring enough system ram will limit the amount of GPU ram used. Hence why you want atleast 16GB of ram for HD and the hardware MPE engine. 3GB+ ram spaces on video cards are for 2K to 4K + frame sizes ie R3D and Raw/CinemaDng. This is because the data per frame multiplies significantly when at 4K resolution. This require far greater ram space which is why you look for the 3GB+ ram space cards for those workflows. The Effect data will also increase because there is far mroe resolution data to alter. This is on top of the drawing out data which is what you see on the screen. That is when the differences for the cards show.

What is the biggest bottleneck on this machine - CPU, GPU, RAM (now at 8GB), or the HD, and would I be better getting a current 27" iMac, a 2012 Mac Mini, or SSDs for my current Mini?

I currently have a 2011 Mac Mini Server. When using FCP X, what is the biggest bottleneck on this machine - CPU, GPU, RAM (now at 8GB), or the HD, and would I be better getting a current 27" iMac, a 2012 Mac Mini, or SSDs for my current Mini?

Hi Tom,
I just wanted to ask you about what you said about the color correction. To be quite honest I'm not sure what the best workflow is, and I haven't gotten my feet wet in multi-cam editing. Basically my work-flow has been.
1) Import from the camera as optimized media - I found that adding color-correction at the import stage cause a severe hang with my tape-based Canon unit.
2) Color-correct the imported files before loading any files into a project
3) Drag files onto the timeline
4) Click on the color-correction box
5) Start editing - Usually I have one camera zoomed a little tighter on the singer, one on the whole band, and my iPad or iPhone camera at different angles so I start cutting things according to who is the focus of the moment, add a Ken Burns effect every here and there, Titles, an occassional transition effect.
6) Add music effects after the looks are taken care of
7) Export
Are you recommending clicking on the color-correction box after everything is done?
Thanks - TZ

Ok, so i bought a imac 27 about 4 months ago, and now they release a new one! ****... So my question is, should I sell this one (which by the way is the i5 2.8 with 1 gb 5750 and 4gb ram) and buy the new imac 27 i5,or keep the one i have and buy more ram

ok, so i bought a imac 27 about 4 months ago, and now they release a new one! ****... So my question is, should I sell this one (which by the way is the i5 2.8 with 1 gb 5750 and 4gb ram) and buy the new imac 27 i5,or keep the one i have and buy more ram. I mostly use my computer for photoshop cs5 and illustrator cs5 for graphics out put as well as surfing the web and music.
Please give me you thoughts on what I should do!! Thanks lot!

The new iMac is about 25% or so faster than your current iMac(comparable model would be the 3.1ghz version). There are a couple of things that you will benefit from such as the dual Thunderbolt/Mini Display ports/ which may help with multitasking. The video card in the new iMac again the comparable model being the 3.1ghz is a lotttttttt better than the current one that you have. So thinking of the long run those few things may be beneficial for you to upgrade(but it depends on what is important to you).
I had the 2.93ghz i7 version that I just bought in March this year and I turned around and sold it about a week before the new iMac's were announced. I got about $1600 for it, yeah I took a loss but to me it was worth it because my new iMac performs that much better. Now keep in mind I went from i7 to i7...3.4ghz i7 with the 2gb video card. Now I have dual thuderbolt/mini display ports. I have noticed significant gains in my video editing and also in my gaming. So to me it was definitely worth the upgrade!
One last thing, I would not have sold my 2.93 i7 and then bought the 3.1ghz i5, the big reason is because HT(hyper threading), it's only on the i7 model(3.4ghz)... If you take a look at some of the bench marks on engadget, maclife, macrumors, macworld, ****Barefeats.com(they really get into benchmarking)*** you will see charts that will help you make a better decision.
In closing I would say look into it, if you can get a good price out of your current iMac to put toward a new iMac then do it. Like others have mentioned to you, tech changes and Apple will change the tech in these machines next year or do a speed bump later this year or so. One last thing if you go from the 2.8 i5 up to the 3.4 i7, you would definitely see the difference (HT is a must especially for programs that utilize it. You can go to my youtube channel(mob1278) and take a look at my geekbench results.... my 2.93 i7 scored around 10500-11000(8gb ram)...my 3.4 i7 scores from 12700-13000 with 4gb ram....so yeah as you can see big difference. Basically the 3.4 i7 would perform similar or just under a 2.4ghz 8core 2010 Mac Pro which runs you about $3500 with no monitor.... it's your money spend it how you want....and Lion is only going to push it even more when it is released!

My DVR security sofware that I access remotely uses a "dvr .ocx" file....when I try it in Firefox , either the latest non beta (3.6.1.5) or the new beta version (4.0 rc) it will NOT work as it says the plugin is missing... it works in IE 8,but not IE9...

My machine is Top of the range (my Company builds them so it had better be :) )
Amd 1100t , 8gb ram , Windows 7 64 bit etc, etc...
The is not a hardware problem , but a software problem with FF...Any help would be appreciated as I hate using IE 8 for anything at all :( but I have to keep it on my machines just to run my remote security cameras at my Computer shop ???
Original question...as question length is limited ...not very bright that limit by the way :(

As I own a Computer company I am fairly computer literate but cannot find a plugin that allows this to work in Firefox.... but I would have expected it to work in the new Firefox :(
All the best, Brett :)

The longer this thread continues, the more ancillary comments you throw in that aren't directly pertinent to your problem with your DVR software not working with Firefox 4.0. Sorry, I don't intend to continue with this discussion.
I do agree that ''something'' needs to be done better with regards to plugins for Firefox, but I do disagree with you as to whose responsibility that ''something'' is.

Is it normal for my computer to slow the more pdf's I open?

I think my computer should run better with what I need to do in a day, But opening pdfs then attaching others in emails, my computer breaths hard and is slow.
It may have to do with watching webcasts and not being able to play any videos or games from Facebook.
My computer is an AMD A6 with 8 mg ram running Windows 8.
Thank you for your time and answers.

Have you checked your resource usage using Window's Task Manager?
The more you have running the slower the computer will run.
What is your video card or cards and how much ram does each have?

Should i Take the more expensive Mac mini (quad core) or dual core

Hey guys!
I don't now if I should take the Mac mini with dual core or quad core
I have never had a Mac so I don't now if the quad core (200$ more) is better than the dual core :o
I use it only for standard things (email, web, twitter Mac App Store games)
But it also should not stuck at bit more powerful apps and run crystal clear !!!
I want to have the Mac mini for few years !
Thanks now!

The difference in real performance between dual core
and quad core machines is highly dependent on the
apps one uses and how many at the same time.
If you really only ever have one or perhaps two apps
open at once and if these apps are like web browsers
or email, you may never really notice a difference.
However, if you have many apps open at once or use
apps that can utilize many cores at the same time (typically
imaging and video apps), then there will be a significant
performance increase.
As far as gaming, by and large the most significant impact
on game performance is the graphics processing unit (GPU).
The integrated Intel HD4000 GPU in the Minis can typically
handle mid range games but will struggle on the very highend
games.
Also, if apps are not designed for mutiple core usage, there will be
now real improvement between 2 or 4 core machines. As a matter
of fact, I have a few apps that are faster on my MBP 13" 2.7 GHz
2 core i7 than on my quad core i7 2.0 GHz Mini Server for this
very reason.
So, the bottom line is that for some a quad core machine will
blow away a dual core machine while for others, there will be
no noticable difference.

3rd party RAM opposed to the RAM sold by Apple

I'm looking to upgrade my RAM to 4GB and I've seen the $300 RAM sold by Apple and other RAMs for like $45-$60 everywhere else. My question is: Why the big price difference? I was doing a little research and I read that with the aluminum Macbooks, anything but the RAM Apple sells will lock up you computer and lead to constant crashes. Is this true, or can I save my $215 and get the 3rd party upgrade?

just be careful when installing your new ram if you're not all too familiar with hardware installation.
1. ground ground ground. ground yourself before touching the inside of your macbook and before handling the ram sticks. if you're not aware, you can bond yourself by touching any bare metal surface on the macbook.
2. use a static free surface or use an insulating mat.
3. handle the ram by the edges of the circuit board and avoid touching the chips or contact edge.
4. observe the ram already in the macbook before removing... specifically take note of the depth the contact edge is inserted into the slot. when you install the new ram, make sure they are fully seated based on your observation of the old ram.
i cant stress this enough, as most of the problems previously stated and the "symptoms" sound more like fried ram than incompatible ram. this is likely due to people not bonding themselves and accidentally zapping their new ram due to improper handling. granted, there's a lot of cases of poor quality ram causing some peoples' problems, but i'm willing to bet a significant ratio are due to careless or improper handling.
if vendors like crucial, ramjet, and OWC were selling large batches of questionable ram, i'm sure they wouldnt sacrifice their reputation by continuing to sell product known to be bad. just stick with a reputable vendor and you'll be fine.
i read all the same info as you did, and i purchased my upgrade from ramjet based on their claim that they test their ram in the actual computers and not on just a test bench. sure, i was already skeptical of most peoples' claims of "bad ram" but i chose to CYA at the same time and my upgrade has gone just fine.
and no, i dont fear that "it'll go bad after a few weeks" because that's not how memory works. for those that had that happen to them, it's because they zapped their ram due to poor grounding/bonding practices.

I have a Power Mac G4 1.25 Ghz 1 GIG Ram, what is the latest OS X I can run?

I have a Power Mac G4 1.25 Ghz 1 GIG Ram, what is the latest OS X I can run? I am currently running Jaquar. Where can you obtain older versions of OS X?

Actually you can run up to Leopard 10.5. It requires a G4 867mHz processor so you are comforatbly over the minimum specs.
That said, I offer two caveats regarding Leopard that may make Tiger 10.4 more appealing:
1) Leopard may want more than 1G RAM. With currently available modules, you can take your Max RAM to 2GB. You can install up to 2GB RAM.
2) If you don't have a video card that supports Core Image, things can be choppy. My 1.25 G4 is a tad sluggish with Leo because I have the original ATI Radeon 9000 64MB VRAM vid card. If you have a Redeon 9600 or higher, you likely have Core Image Support. Use System Profiler to Identify your exact video card. SP is in Applications > Utilities. Select "Graphics/Displays" from SP's "Contents" pane on the left to view the specs of your card in the main pane. It wil tell you if Core Image is supported.
If you can get Leo running fine, it's better in that many programs no longer support 10.4.
Looks like yo uare in the Continental US. Call Apple at 800-MY-APPLE and ask for an operating system specialist. Tell them you need 10.5 to support new hardware. I bought that way in March, and it sounded like they wre going to keep Leo in stock for a whie because of the larger number of olders Macs that can;t run Snow Leopard or Lion.
Be very, very careful of Mac OS software on auction sites. I've seen too many that were improperly described and would not work. Likewise the gray Leopard install disk that came packed with another Mac model won't work.
I just checked--OWC does not list any Apple System software at this time.

To ram,or not to ram,that is the question.

I have a first edition g5 dual 2.0.Ever since I have had this computer I have had this problem where when booting the computer will freeze at the grey screen at start up.This seems to happen to me when I install ram.I have been through 3 episodes where after installing ram the computer would not boot past the grey screen with the apple logo.I will not document all the episodes,but it happens like this a couple of months back I had 4gigs of ram installed in my machine.I had purchased 6 more 1 gig sticks and was going to attempt to max out the slots.I removed the bottom apple stock 256 ram modules and put in 2 1 gig modules in the place of them.I went to boot the machine I see the apple logo,spinning wheel,the wheel stops,will not boot past grey screen.So I took out the newly added modules and put in 2 different 1gig modules,same brand,grey screen,apple logo,wheel stops spinning,no boot.I put in the 2 original apple modules,now it does not boot with them installed.I take out all the ram except the two stock modules,and disconnect the spare hd.I try to boot everything stock,same thing,stuck at grey screen.I tried to boot the machine the next night,after over half a dozen attempts I was able to fully boot,once I was in I decided to reinstall the the os,10.2.7 that came with the unit.I did a complete reinstall.When I was done I tried to restart the computer,it froze at the grey screen.I have a g5 imac at work,and at home.I used those machines for the next three months,and one day I had a chance to start early with apple tech support and maybe resolve my issue.I had done some rearranging in the other room so I moved the g5 in there.I hooked up my apple 15" cinema display plugged her in and off she went,it booted with no problems!Why?How could this be?So I have been using the unit for the last few months stock configuration,updated 10.2.7 to tiger,currently with updates at 10.5.All I have used the unit for is ripping movies with handbrake,done at least 200.There is only about 1 month left on my warranty,I have been interested in selling or trading the unit before my warranty runs out.Last night I plugged the cables back into my spare hd.zeroed out the data rebooted all was well.I took out the stock ram,install 2gigs of the ram I had tried before,I reboot,apple logo,no spinning wheel,freeze at grey screen.I found this last episode the weirdest with the grey screen on this attempt I did not get the spinning wheel,the wheel did not show.I shut down and installed 2 1gig sticks that originally worked.reboot,grey screen,logo,no wheel,no boot.I reinstalled the original ram,same as above,grey screen.I started up in safe mode.Repaired disk permissions on the maindrive,run mac janitor,run mem test,mem test reported ram to be ok.I reboot,full start up!What is the deal here!Where do I go from here.On one occasion I called tech support they told me to system diagnostics disk,have done this twice in the past,system passed all test.The way the system sits now its fine,i'm affraid who ever I sold it to would install ram and go through the same ordeal.And I do not want that.I have thought of trying to do the ram install again,then If it freezes boot into safe mode,repair permissions,run mac janitor,run mem test and see if I can get it to work that way.Should I try to run the diagnostics to see if the system passes all the test?My unit is also eligible for a power supply replacement,should I call and have that done and mention these problems?I am all ears.I am open to all suggestions.If you read this far then god bless you!Sorry for such a winded post it could have been longer.

Is it possible to upgrade the graphics card on a mid 2012 MacBook Pro? And is it possible to upgrade the RAM without voiding the warranty?

Hi I was wondering if it is possible to upgrade the graphics card on a MacBook Pro and the RAM without voiding the warranty? I have a gt 650m in my MacBook Pro, non retina, and to me, its not enough power for me, so i was looking around, and I found a retailer that would give me a nvidia gtx 660m for a decent price. Also, the ram needs to be at least 12gbs, to ensure that my computer would run fast.
If you can help, please tell me,
Thankyou.

No, the video card cannot be exchanged - you have a pretty decent GPU there; not sure why you'd want to switch it out. You can upgrade the RAM to a maximum of 16GBs. Apple recommends upgrading in matching pairs, so I don't really think I'd try 4GB and 8GB stick.
Both Crucial and OWC have memory available for the new Macs. Both are reputable dealers and know Macs well and I would only buy from these sources (and I would buy Crucial, were it me).
Although your Mac didn't come with a users manual outlining the installation of the additional RAM, you can download the late 2011 model users guide as the models themselves are almost identical.
Good luck - write back with any questions.

It´s possible to upgrade from the latest mavericks beta to the final version?

Hi all. I´m thinking in becoming a developper because I want to install mavericks beta on my macbook pro (I can´t wait for the battery and ram upgrades). But i have a question before that. It´s posible to upgrade from the latest mavericks beta to the final version? , or Ihave to restore to mavericks final version and then use a time machine Backup?
Thanks in advance.
Sorry for english

No one who knows can say, because Mavericks is not released yet.
To get a Free copy that can be updated, you need to have a paid developer membership, at a minimum cost of at least US$100/ annually. (This may also include one Developer Tech Support incident and other benefits.)
Apple has lowered the cost of new versions of Mac OS X to about US$20. If Mavericks is released at about that price, buying a legitimate copy instead of depending on a quirky developer version that cannot be updated should not be a difficult decision.

GPU RAM (the more the better?)
