View Full Version : dual core no faster than my P4

I've been using RBpro with HCenc for a couple years now and recently loaded it on my AMD 64 X2 laptop. I can see the 2 processing windows come up and working but the end result is no faster than when using my P4 desktop computer. RB is set for multi-processing in the laptop. Either computer take +/- 4 hrs. Did I miss a setting or something? Thanks, any help is appreciated.

Could possibly be disc speed... I can only say from my experience that a dual core is a lot faster.

How much, if anything, gets cached into memory ? I'm presuming little to none if disc speed is a possible factor.

true resetting the DMA on the drive?
go into device manager, and remove the drive, and reboot
it'll reinstall the driver and set it back to DMA mode
I've had to do that a few times

Could you elaborate, I assume you mean reader/burner speed? Is there anything I can do to check or fix it? What is a reasonable speed for success? It is a Toshiba laptop AMD 64 x2 with a Matsushita (?) Ram drive. It has been burning my Verbs at approx. 8x.

follow my instructions just a couple posts up to see if the optical drive was dropped out of DMA mode
but you said it was burning at 8x so I doubt it

I'd seriously consider re-installing your applications though, and possibly looking for updated processor drivers

maybe a little more information as well?

If you are reading/writing to hard drive and the disc is fragmented or is close to full the speed can be dramatically affected. If you are reading directly from optical drive (e.g. through AnyDVD) sometimes the drive itself is really slow (I've seen it take twice as long as a hard drive version).

I am reading thru the optical drive with AnyDVD. How do you usually do it? Do you rip to the hard drive separately then process with RB? This is better/faster?
By the way DMA is enabled and HD has plenty of space and is not fragmented.
Thanks.

I usually rip to hard drive first -- and then run DVD-RB against the HD copy. I'd guess you would see better speed that way, especially on a notebook computer.

Does the laptop go into any sort of "low power" modes to save energy ? A few years ago, and they still may, laptops had a "step-down" mode where it would reduce the actual clock speed of the CPU. If it's hooked up to AC power, I don't think it should, but who knows.

As for your DVD drive's "burn" speed, that means nothing.

I'll try the next one by ripping it to the HD first. The laptop power setting was on performance and plugged in to the AC adapter so that isn't the issue. Thanks all for the help.
