Benq dw1655 buffer level problem

vbimport

#1

Hi everyone!
I’ve got a little problems with my new ( :wink: ) DW1655 BCDB.
The first problem affects buffer level during burnin (no matter is it nero or imgburn) - it’s really weird because it’s changing from ~20-95% all the time.
All these things happen with MCC-004 burnin at 12x or 16x. Furthermore during @16x burning speed achieved 12x and than it stops rising but oscillate about 12x. WOPC is ON, SB default.

And the second problem - if there is a disc inserted into BenQ the green LED burns all time. There is no difference if I do smth with the disc or not.

Any ideas? :expressionless:

For the 12X limitation, are you using an external case ?

Maybe you should check that DMA is on too.

This variation 20-95% in buffer level are normal with 16X drives using WOPC.

This is normal behaviour.

Which buffer are we referring to?

@ItalianJob
no no, it’s internal version. DMA is on also (Ultra DMA 2).

thanx for quick answer, that calms me down :slight_smile:

@TimC
talkin about burner’s buffer, not read


#5

ok. that’s another example

both @16x

All default

and here is the best one
SB default, WOPC off

i have no idea what’s going on and i’m really upset :confused:


tommorow i’ll test benq with other computer

sorry for post beneath previous
