Inconsistent Burning Speeds

Recommended Posts

What ever burn speed I select, ImgBurn will write 2 speeds below it. Ex: When I select "8X" burn speed,this is what I get: " I 18:30:51 Average Write Rate: 5,548 KB/s (4.0x) - Maximum Write Rate: 8,662 KB/s (6.3x)".

 

These are the blank disc's I am using:

roll back the ide driver to the default xp sp2 one

I have the deluxe model of that asus mobo and the driver from asus is old and buggy. Some of my 12 x burns took 15 minutes???

Course I had a bad sil 3112 driver on top of that.

The 3520 is in my closet. It was in my second PC but, that PC blew up. So I took out everything that was salvageable and chunked the rest in the trash.

 

I'll try to roll back the drivers chewy. :)

I have to say that I have burnt a lot of discs recently both for viewing and as part of the tests and I haven't seen the burn speed problem jmet. :huh:

I watched it today while I was burning. It gets to 4.1X by 4%. From there it reaches 6.2X at %35, then goes back down to 4.1X around %40 and stays there until it is finished. Even though I selected 8X speed.

 

Here is the log:

time for a clean install, load windows xp sp2 and then go into device manager and only deal with yellow exclaimation marks

That's what I did!

 

there is one other option, disconnect the slave and reflash as standalone master in safe mode

 

try option 2 first, it's easier!

Maybe WOPC is kicking it back down? I guess that would mean the firmware isn't so good for doing 8x burns on that media - or rather 6x if that's were it's dropping back down.

 

Look at the write speed graph via dvdinfopro. You can even post it up here so we can take a look too ;)

Well, this is wierd.

 

It started out the same as before. Although, it took until like %40 percent before it would go past 4.1X but, it got all the way up 8.4X by the end.

Is that hacked firmware jmet ? I just wondered if your results are more consistent with the stock NEC firmware ? :huh:

Yea it is.........I get all my NEC firmware from here: http://www.micheldeboer.nl/firmware/

 

(I re-installed the same firmware again, and I installed the NEC 3520 in this PC. I will try later on testing them. Right now I am installing all the software for my PC, as I just got done reformatting.)

Looking at that graph, I'd have to guess the 2GB mark is where it would have stepped back down to 4x again (from 6x). There is more WOPC activity there.

 

If / when it steps back again, repost the graph ;)

Thanks for the reply LUK!

 

Excuse my ignorance here but, what is "WOPC"?

 

It is how we learn after all. :D

Walking optimal power calibration - something like that anyway - depends on where you read it!

 

It just basically means the drive checks the burn quality as it writes - and if found to be substandard, it'll reduce the burn speed.

what's puzzling me was you got those verbs a while back and you have

had that firmware for a while too?

This computer intially had 1 stick of Corsair 512MB of RAM.

 

I bought another stick of that same RAM for my second PC (which I no longer have). I ended up giving that stick to my mother cause she only had a 128MB stick in her Dell.

 

My brothers Compaq PC crashed on him so I robbed a 512MB stick from it.

 

I then put the 512MB Compaq and the Dell 128MB stick along with my Corsiar 512MB stick.

 

I learned the hard way not to mix RAM. It won't happen again. lol
