I just added an extra 4GB RAM and my computer is slower….8GB!
Really, I thought RAM was supposed to speed up the process, my motherboard supports up to 32 GB RAM and i upgraded to 8GB from 4GB….what is going on?!

Possible things: your RAM doesn’t properly match; you have dual-channel and didn’t install in pairs; you have 3-channel and didn’t install in triples. More details, please! (motherboard, RAM type(s), OS, processor, etc.)

You have to run a 64-bit OS to use more than 4GB, what are your specs?

I run windows 7 ultimate, have an intel dual-core xeon 3ghz processor with an intel s5000psl serverboard.
i have 4x1GB kingston 533Mhz DRR2 ECC FB CL4
and 2x2GB kingston PC2-5300 FB DIMM
I have 8 slots for RAM on my server board and it supports up to 32 GB.
thanks for helping me out with this!

Is the second set of ram ECC also??, the ram is also two different clock rates

Tyler – click Start, then click Control Panel, then on the upper right there’s a menu that says Category. (or possibly Large Icons, or Small Icons) Click that menu, change it to Small Icons, then click on System. Now on what you just opened, find where it says System Type: and it will say 32-bit Operating System or 64-bit Operating System. Which is it, 32-bit or 64-bit? If it’s 32-bit, you need to reinstall Windows with the 64-bit version. (your copy of Windows 7 includes two discs, one is 32-bit and one is 64-bit)
32-bit operating systems, whether they be Windows, OS X for Macs, Linux, etc. can only use just over 3 gigabytes of RAM; so the extra 5 you have are sitting there doing absolutely nothing if this is the case.
If you ARE running the 64-bit version, then as the first reply said, it must be either because you’re not running in dual channel mode (cuts the overall max speed of your RAM in half) or your newer RAM has slower timings, and the RAM you had before is forced to match it. Most likely, you’re running a 32-bit version of Windows, though; and there’s no way to convert it to 64-bit, you have to format and install Windows from scratch to get to 64-bit.

it’s 64 bit. it registers as 8GB RAM. just slower on rendering…

here’s the link to the 2X2GB RAM i brought in
https://www.memoryexpress.com/Products/PID-MX14465(ME).aspx?curtab=0
so EEC as well, not sure how to set it up for dual/tri channel…
basically there are 8 slots, A1, A2, B1 , B2, C1,C2, D1, D2
from my understanding you go in this order A1, B1, C1, D1, and then stack in ram in the slots of A2, C2, etc….
but i also read tha the pairs ie. A1,A2 must have the same sized ram in order for it to read it properly, but that didn’t work.

one thing i notice in the task manager is that it only uses up to 3.45 GB of RAM even though under physical memory it says 8gb.
under the System heading on the task manager for Commit (GB) it reads 3/14….not sure what to do with this mess.

found the answer….
Well, CS4 is not a 64-bit program. Even though it will use the 64 bit architecture to increase rendering time, it still doesn’t use more than 4GB of RAM so adding more is useless. If you want fast playback, a faster graphics card would help you more than more RAM, if you want faster rendering, get a better CPU.
I’m assuming you’re talking about AVCHD here and not any other HD format. In which case fast rendering and RT playback isn’t going to happen. Not on Premiere or any other NLE. Not without transcoding into something else
now we know. looks like we’ll have to wait until CS5 comes out with the adobe mercury playback engine.

As long as you’re running 64-bit and have a processor with more than 1 core, CS4 can use up to 4GB of RAM per core, so no, it’s not pointless having more than 4GB…
I see you bought PC5300 (667MHz) speed RAM. That is almost certainly your problem. Most DDR2 systems are PC6400 (800MHz) so if your existing RAM was PC6400, and you added PC5300 RAM, your computer has to force the existing RAM to go down to the PC5300 speed, since no computer can run RAM modules at different speeds. Return your memory and get some PC6400 speed stuff; also, getting ECC RAM is pointless unless your existing RAM is also ECC.
