Faster memory: does it make a difference for image processing?

[Tony Printezis]

Hey guys,


I'm planning to build a new workstation in the new year. Is it worth getting faster memory for it (DDR3 2000, instead of DDR3 1066/1333)? Does anyone have any first-hand experiences with faster memory actually improving image editing / processing times?


Thanks,


Tony

Will the processor, motherboard and bus system actually operate at the higher speeds? If not you will not see any speed increase. It can only operate as fast as the bus system. You have to buy memory as fast (or faster) as the bus system or it will not recognize the memory.


So I would buy a processor and mobo that support the fastest RAM available. Even if the speed increase isn't mind boggling, at least your computer won't be out dated as fast. And I'm sure if you put a stop watch on a series of functions you see some slight increases.


Lots of RAM will show you the biggest boost.

Only if you can make use of it, if you are only using 2 Gigs of memory during your computing any more is a waste of money. Better off buying faster memory if your system can handle it.

If you are using Photoshop and editing a couple 15+ MP images at a time, I'm pretty sure you won't be wasting RAM.


Not to mention having other apps open. Rarely do I ever have just one open.


You'll probably want more RAM.

A quick way to check how much ram you are using it use task manager, you can see exactly how much ram you are using. I don't need more than 1.5 gigs.

With Photoshop and Aperture both open and a normal amount of images loaded, I use 3.82 gigs of my potential 4 gigs.


Image data loads into the RAM while the file is open, if the program runs out of RAM it accesses virtual memory which is your hard drive which is substantially slower than RAM. Speed of the RAM isn't much help when you are accessing VM.

Hi,


Based on many benchmarks and articles at www.tomshardware.com (great place to go by the way... if you're building your own computer or upgrading one -- forums are especially helpful there), I think it's safe to say you won't see much of a difference at all between those different DDR3 speeds. What CPU are you going to put in your workstation? Because unless you are putting either an Intel Core i5/i7 (DDR3 required) or a new AMD Phenom II (usually DDR3 required) processor in there, you won't even see much benefit from DDR3 vs DDR2 memory. However you will benefit with lots of RAM, as some have already said here. I recommend at least 4GB, but no more than 6GB. Even though your system may only use half of the memory available, it will be much more speedy than it would be to have only what your system actually uses. In the case of DDR3 memory, more is better than faster. Though over 6GB doesn't usually see much gain in speed. 4GB works great for my Photoshop, Lightroom, Dreamweaver, and other CS4 uses.


Hope this helps. Let me know if I wasn't very clear on something.

I've got an i7-920 with 6GB 1600Mhz ram. Still touching the 6GB in taskmanager sometimes. Especially when editing large groups of photo's, say change the WB for 100 photo's at the same time in lightroom or converting your raw files to jpegs.





The speed difference is to small to really notice, unless your overclocking your system.





Fast harddrives are really important. Best is to get a separate harddrive for your operating system and programs and a second for your photo's. Or maybe even more and more splitted into groups. You're gonna notice an increase in speed with multiple harddrives more than with faster memory.





I say 6-8 GB depending on the dual or triple memory bench and at least 2 harddrives (no I'm not talking about external usb harddrives).

I have not found that to be true, I have put 6 gigs and 1.5 gigsandthere wasabsolutely no differnce at all. I made a huge differnce when I put faster ram, as long as your system can handle it of course.

RAM's cheap - buy up.


You will always get better performance out of having more memory - especially when doing multiple tasks (provided the Motherboard and CPU are up to scratch)


Also depends also which operating system you are using. If you have Windows Vista then you wouldn't want any less than 4Gb of RAM (1066MHz or higher) as Vista is a memory hog. I've mentioned it before - buy a 64 bit OS and install 6Gb+ of decent RAM and you will never have an issue.


On a side note: If exporting from Lightroom or similar, you can take advantage of your processor's dual core/ quad core capability by running 2 processes at the same time. Say you are exporting 100 photos to JPEG - start the export on 50 of the images first, then do it again with the remaining 50 images. It will take half the time as each process is utilising only one core.


Beforesomeone tells me I'm pulling your leg - I've tested this and it works, not quite half the time but it's pretty damn close.
