Would Dual-DDR help alot?

[GreatKent]

I did a search in the forum, it seems it's commonly said upgrading memory from 256Mb to 512Mb won't help boost the encoding speed much.
I don't know if it's the case in Dual-DDR, since the bandwidth will be doubled as well.
Do you think upgrading 256MB of DDR333 to 512MB would help much?
Have a nice day^^

Hello!

Don´t think so. The encoding speed mainly depends on the CPU and the system BUS. It has also been reported that dual memory can cause CCE to freeze. But upgrading the memory should give you better performance, if you want to work on the PC during the encoding process.
To find it out really, you should start your own tests ;)!

Dual DDR may cause CCE to freeze? How likely is it going to happen?
That really scares me since I have been in hot water when CCE started to freeze.
I have encoded around 10 movies using my old system(Celeron 800, o/c to 900), CCE never freezed. But after I upgraded to AMD XP1800+ with 256MB DDR333, though it's much faster, CCE freezes quite often.
I am recently encoding an anime episode consist of 7 DVDs. I have successfully encoded the 1st 3 discs, however, CCE started to freeze with the 4th disc. I just have no any ideas what has gone wrong!! I have spent a week searching in this forum for help, and I have tried every thing listed in the FAQ60, except turning off VirtualDub's AVIFile Proxy mode, because I don't know where to set it. Even after switching to TMPGEnc, the problem persists.
I have found something strange about the "Safe mode(frameserving)" in the Encoder tab --
if I check the safe mode at the beginning of the conversion, the encoded file ends up showing "Unrecognized Exception! (E:\DVD\Chess\disc5k\AviSynth Script File.avs, line3), I then re-install my Windows2000 Pro and re-rip the DVD, I encounted exactly the same error. However, I accidentally discovered that if I didn't check the safe mode(in the Encoder tab), start conversion, close DVD2SVCD when CCE starts encoding, and use recover and check the safe mode(frameserving), CCE seems to be working fine, it's now still encoding, I hope it won't freeze this time...

I have been running Dvd2svcd with 512 of DDR ram for quite a while and had no idea how much difference it made as I upgraded the processor at the same time.
Recently I decided to buy myself an aluminium case, transplanted everything over and it started up fine.
I noticed everything seemed a little sluggish and when it came to encoding a film CCE was running at probably 3/4 of the speed it normally did...it turned out to be 1 stick of 256 ram was not pushed all the way into the slot so the machine was only running on one engine so to speak..with it pushed fully home my speed was back to normal.
Therefore I would say extra memory made a fair bit of difference in my case...but then that could just be me :p

If you read up on the hardware sites Dual DDR doesn't really do much at this time since memory bandwidth with the current FSB speeds is about at where it should be. It might speed it up a bit, but nowhere near the amount that DDR did to SDRAM.
Your money is better spent going for a faster CPU if you already have a decent setup otherwise. However if you are planning on upgrading your motherboard anyway why not go to one of those nice Nforce2 boards. If there was a compelling CPU reason to upgrade that is what I would go for.

My take on is 512 better then 256. Yes and no. 256 with nothing else running on the computer and you are not using it is plenty and upping it to 512 shows little to know speed increase.
However the moment other programs start to run and when you want to use the computer while encoding adding that extra 256mb's is a big deal. Although many say going to 384 is enough, but I have never tried that.

Hi Markrb
I am in the process of trying to decide what to upgrade to. I hear there are processor price reductions coming today! maybe even 30% drop on 3.0GHz! Still too much though:(

I am nearly set on getting the Gigabyte GA-8INXP motherboard, but are you saying it's not really that beneficial for reducing the encoding speed for CCE? Maybe just an ASUS P4PE is good enough even though in my area the Gigabyte is only about $40 to $50 more.

I know mostly AMD so if you are thinking a P4 that is a different world.
I would say that I am not a Gigibyte fan myself.
I others much better.

If that Gigibyte is the new Sis chipset have a look at www.anandtech.com he just did reviews of the 3 or 4 current SIS boards.

i just built my P4G8X dual ddr board with 2GB DDRAM

running it @133FSB 2-2-2-6 don't notice any speed advantage from my P4PE/P4B533 systems

but haven't tried @172FSB yet

Mem-size usage depends heavily on OS.
