16X

@ala 16X single layer - the above 3 scan were all using Ala42 MCSE Yuden000-T02-000@ Yuden000-T03-000 write stratagy
I have tested this one swap (Yuden000-T02-000@Yuden000-T03-000 with the 1650 and 1655 the read speed patch works fine also.

Few weeks back latest Sony 810 firmwares caught my interest because my DW1640 drive seems to run quieter and smoother, when on Sony firmwares.
With help from ala42 and his MCSE I'm now also able to put this firmware(-s) up to write strategy swapping test.

MID: Prodisc R03 (Memorex branded)
Type: DVD+R 4x rated
Write strategy: Prodisc R04
Burned as: Nero Create Data Disc
Burned at: 12x speed
Burntime: 6:30
Drive/Firmware: BenQ 1640@Sony 3.0e firmware, WOPC on.
Note, used my 1620 for scan results because Sony doesn't support this function correctly..

Sony 810 firmwares lack support for RICOHJPN-R01 media... Had to import this MID into firmware first.

MID: RICOHJPN-R01 (Datawrite Classic)
Type: DVD+R 4x rated
Write strategy: RICOHJPN-R03
Burned as: ImgBurn 1.2.0.0 (old ISO image, movie)
Burned at: 8x speed
Burntime: 8:20
Drive/Firmware: BenQ 1640@Sony 3.0e firmware, WOPC on.
Note, used my 1620 for scan results because Sony doesn't support this function correctly..

More tests with my 1640 on Sony 3.0e firmware...

MID: MCC-003 (Verbatim 43481)
Type: DVD+R 8x rated
Write strategy: MCC-004
Burned as: Nero Create Data Disc (image, 4433MB old movie)
Burned at: 12x speed
Burntime: 5:51
Drive/Firmware: BenQ 1640@Sony 3.0e firmware, WOPC off.
Qulity scan done with drive on default firmware because Sony doesn't support this function correctly.

Note. Out of this (and above) burns it's questionable if SolidBurn really ads that much to quality when you burn good quality media.
Anybody suggesting Sony 810 owners to crossflash to BenQ firmwares the first they do, have some good thinking to do first. With latest firmware these drive comes on pair with any BenQ 1640.

Benq 1640 FW doesn't support ANY 4x or slower +R/-R media that I'm aware of (not including RW media), although it burns RICOHJPN R01 just fine with SB off at 4x. Also burns Ritek G04 and CMC R01 at their respective speeds very well with SB off, despite not having write strategies for them. For not having actual write strategies for these slower discs, it certainly does a good job.

off topic
With that said, 1640 drives have no problem to burn lower then 4x speed.

RICOHJPN-R01 will burn very well at 2.4x speed. Firmware BSOB, SolidBurn and WOPC enabled.
Check out link_1, link_2, link_3.

Does that mean that you are not able to burn at 4x, or are you just pointing out that it burns at 2.4x as well?

off topic
I'm just pointing out 1640 drives are able to burn low as 2.4x on +R's.
Your post could bring people to think otherwise.

With RICOHJPN-R01 I can burn at; 2.4x, 4x, 8x, 12x and 16x. (Did I forget some speed... .) Depending on write strategy used.

Note, Nero gave me option to burn at 2.4 although you say there isn't a write strategy lower than 4x in firmware...

But, let's stop here and return on topic.

Compare with same media/speed when burned with 1640 BSLB firmware

zevia, alan1476,

ive used the method below to swap the t02 strat for the t03:
- changed YUDEN000 T02 to YUDEN000 Tx2
- changed YUDEN000 T03 to YUDEN000 T02

but i am unable to burn successfully @ 12x, i can over speed using default t02 strat to achieve 12x,
but wopc, and sometimes even sb, gives more pie/pif errors than burns without either.
i can even burn @ 8x using the swapped t03 write strat, but just not @ 12x!

was there something [special] u did for ur first [several] burns, b4 achieving the same quality as 8x
burns but actually with 12x? ive posted about this in post #1 of 1655 and its unending problems!!!,
and in post #19 of the same thread. i would appreciate any help u can provide me with this problem.

I'm not surprised...
You replaced a given 16x write strategy with a 8x (or "generic" one). Don't think it will ever work any good.

Removed off topic pic.

pinto2, im kinda confused as to what u said, and if that picture is any indication, it looks like
ur replacing the t03 strat with the t02, is it? coz i did exactly the opposite, i renamed t03 to t02
strat so i could burn @ 12x without wopc/sb/os [and renamed t02 to tx2!] i swapped the strats
[t03->t02 using mcse]

b4 reading zevias post [#305 & #306] as my 12x burns was exactly like zevias on post #305,
even tho he managed good quality burns after using the renaming trick, my burns on the other hand
are still the same!

if this approach isnt going to work then how come zevia did it [in page 13, post #305 & #306]? or
how did alan1476 do it [bottom of page 13, post #325 and top of page 14, # 326 &327]? btw thanx,
hopefully ull be able to help me with this, as i wasted quite a few ty02's trying to burn them at 12x!

i would like a way to burn these disks at 12x without the default t02 write strat and wopc+sb+os,
especially wopc as it produces too many pif's, and turning it off reduces the burn speed to 8x even
if i select 12x and sb+os is on!

I did exactly as you have illustrated. I used MCSE to change the name of Yuden000-T02-000 to Yuden000-Tx2 then proceeded to change Yuden000-T03-000 to Yuden-000-T02-000. Just a name change. Just a note I have found many Sony Yudens to be defective with dye spotting, you almost cannot see them until the disc is burned but after the disc is burned they are very visible.

weird, i did the exact same thing for the 1640 [bslb] & the 1655 [bcdb], i used the old swapping method for the bslb.
which resulted in 1 very good burn [like 8x] and i that failed the trt but was excellent in pie/pif in the 1640, and
2 [4 in total] coasters in the 1655!

well i dont have sony, i have oem ty in 50pk cake boxes, which i bought from newegg. however after reading
about the dye spotting that u mentioned in the previous post, i turned the 4 coasters over to take a look
and saw [slightly] diffrent colored [circular ring] in the burned area towards the end, id guess about
700-1000mb in size. when i compared these coasters to other 8x and 12x burns that were successfull i
dont c the same discolored circles!

alan1476, if u dont mind me asking a few questions:
did u use the rpc-1 build of the firmware by the tdb, or the cvt or the exe provided by benq to flash ur drive?
did u enable read speed hack when u swapped the write strat using mcse?
did u use, wopc, sb, os [unlikely as u used t03 strat] or any of them in combination?
are u using a rounded/flat ide cable?

i did c that u enabled wopc for the first and disabled for the 2nd burn, thats what screwed up the first burn i guess.

heres the facts so far:
1] i can burn @ 12x [mcc 004] on the 1655 <<- drive cant do 12x burns ruled out
2] i can do 8x [with t02 & t03 strat] on the 1655 <<- defective media ruled out
3] i can do 12x [with wopc+sb+os & t02 strat] on the 1640 <<- batch unsuitable for 12x burns ruled out
4] i can do 8x burns [with both t02 & t03 strat] on 1640 <<- defective media ruled out
5] changed rounded cable on the 1655 <<- defective ide cable ruled out, i can try another [flat] cable
6] u and zevia tried the t03 strat, by renaming, on the 1650 & 1655 <<- defective t03 strat ruled out

now u tell me what else ive missed here, i cant make any heads or tails of this problem!

Let me see, I want to give accurate answers to these questions so I will number them.
1. I used .cvt firmware that I got from Zebadee.
2. No I never use the read speed hack, I believe I get a better transfer without it.
3. No, when using MCSE I leave everything in QSuite at default
4. At Ala42s request I use a flat 40pin 80conductor ribbon.
5. I tried one burn with WOPC enabled and found that my PIFs were lower with it disabled with Yuden000-T02-000 media.
6. If you are using Clone DVD (Elby or Slysoft) you might have a problem with burning with QSuite SB enabled OS enabled. I do. Others do not. I did my test burns with Nero recode and a French Companys tool (VSO) CopytoDVD.
With Clone2DVD I get horrid burn with QSuite and Solid burn enabled and OS enabled@12X but good burns at the default 8X speed. I need MCSE to overspeed media or use another program to use QSuites Overspeeding (CopytoDVD).

thanks for ur help, ill try that. btw how did u chieve 16x speed in the trt on post #327 without the read speed hack?

also if u dont mind, what version of mcse did u use to rename that t03 write strat?

I achieved that with a beta firmware direct from Ala42 while we were beta testing the new firmwares from BenQ. It was just a firmware that Ala42 put together and gave me, I have since deleted it because it was just a beta and unusable again. I believe it was Version 1.0.8.2.

I know very well what you did in theory . BenQ write strategy swaps has been around for almost 1½ year now.

But theory and real world is not always the same thing. We still don't know all the secrets about firmwares and how flasheprom/drive interprets the information in firmware (after a write strategy swap, you'll see more on this later down).
Primarily I had this thread in mind when posting that pic (more as joke). Sorry about that.
----------------------------------------

There are two (sofar known) ways to change write strategy in firmware with MCSE. One is to rename a MID and "kill" the MID/disc you use, the other to replace MID's write strategy with another's MID.
Maybe you say; hey, isn't the affect/end result the same?.. My answer is; "most probably" no! But I can't explain in technical terms why this is so, simply because I don't know. Better to post some burns.

I have made three burns in a row with exact same settings and media, two with write strategy "rename" and one with write strategy "replace".

MID: YUDEN000-T02 (Verbatim 43481) MIJ

Burn1. Write strategy rename (changed YUDEN000-T02 to YUDE000-Tx0, renamed YUDEN000-T03 to YUDEN000-T02).

Burn2. Write strategy replace (YUDEN000-T02 with YUDEN000-T03)

MID: YUDEN000-T02 (Verbatim 43481) MIJ
Type: DVD+R 8x rated
Write strategy: YUDEN000-T03 (strategy "replace")

Burn3. Write strategy rename (changed YUDEN000-T02 to YUDE000-Tx0, renamed YUDEN000-T03 to YUDEN000-T02, same as burn1).

MID: YUDEN000-T02 (Verbatim 43481) MIJ
Type: DVD+R 8x rated
Write strategy: YUDEN000-T03 (strategy "rename")
Burned with: Nero CD-DVD Speed Create Disc (image, 4482MB movie)
Burned at: 12x speed (choosed 16x)
Burntime: 6:22
Drive/Firmware: BenQ 1640 BSOB SB/OS=off WOPC=on.
First burn after fresh firmware flash.

Interesting, everything the same as in burn1, but without any visible reason the drive decided to only burn at 12x this time... No consistency, although all parameters were the same.
Why? Don't think it "learned" anything because SB was not enabled. Or maybe it learned anyway. Who knows.

Probably the power calibration at the outer disk part returned too bad values, so the firmware fell back to 12x write speed.

Here is something somebody might find interesting. I have been trying to find a good swap for Yuden000-T02-000 at 12X other than Yuden000-T03-000. After trying many I came accross SonyD21-000. So I did a straight change Yuden000-T02-000 to Sony D21-000. I burned it at 12X with WOPC off and the rest of Qsuite at default. This is the result. I also flashed back to BCDB using a .cvt firmware.
