Performance problems Plextor/Nero/Intel

vbimport

#1

Specs:
HP Vectra VL 800, 2Ghz Intel, 768 Mb RAMBUS RAM,
Primary Master: Maxtor 40Gb 7200 Rpm
Primary Slave : Seagate 80Gb 7200 Rpm
Secondary Master: Plextor 40/12/40
Secondary Slave : HP DVD (some shit)

Latest BIOS version ie.1.11
Latest Intel Chipset Driver
Latest IDE driver
Latest Plextor Firmware, ie 1.02
Latest NERO version , ie 5.5.8.2...have also tested 5.5.7.1

This is my problem. I have 6 identical machines which all have the following problem:

When burning BURN-Proof kicks in as follows:

40X over 100 times
32X over 80 times
24X over 80 times
16X over 60 times
8X Works like a charm.

Im running Win2000,

When Bunring with Nero the read buffer is between 98 and 100% and the Plextors bufferlevel lowers at a fast speed making the BURN-Proof kick in. It seems as there is a problem getting the data from RAM to the burner´s cache...but what?

Anyone seen this before?

Have tested on a couple of other machines both at work an home, but they burn without problem...

Getting kinda desperate here!


#2

More info: I also have 100% CPU usage when burning.
When burning with the same Plextor at hoime my CPU usage is only like 10-15%.
Soemthing is really wrong here…


#3

are you burning from hd2cd or from cd2cd and is the burner on a slave port


#4

hd2cd…burner is master on 2nd channel.
BUT, I have tested the burner as bother master and slave on channel 2. And also as slave on channel1.


#5

did you try to burn from a different hd i think you did and do all the pc’s have win2000 and test another program see what that does.

the pc you tested it on that did it good whas that a pc with the same specs and also win2k


#6

The PC’s that I have tested successful burnings on are:

AMD 1Ghz with 3 IDE harddrives 5400 Rpm WinXP
Intel 1 Ghz with 1 IDE harddrive, 1 Pioneer DVD and 1 LG Burner WINXP
Intel 1 Ghz with 7 IDE harddrives (x-tra card), 2 other Burners WIN2K

The other Vectra Vl 800’s are EXACTLY identical, same OS, same Hardware.

At the moment Im reinstalling Win2k to see if the problem is in HP’s Win2k Installation.


#7

I have tested CDRwin5 with the same results.

I feel that the problem is WHY does nero us 100% of the CPU power on these computers…since nero only uses about 10-15% on the machines where it works like a charm.


#8

The same problem after reinstalling win2k.


#9

have you tryed to enable/disable dma


#10

And how would I do that i Win2K.

Reg.hack???


#11

hmmz sorry i forgot how to do it,

i have win xp on my machine and cant find it in there.


#12

It’s the same with win2k…The OS takes care of it by it self.
So I dont believe that that can be the problem.
Gonna try and install WinXP to see if the problem disappears


#13

Goodluck, im still thinking with you


#14

Thx dude…
I can really use the xtra capacity!
:slight_smile:

I called HP support…must be one of the lamest supports I ever talked to. The referred me around to about 5 different technicians. And the last one said: “Have you heard about http://www.google.com?”

Then I told them alot of things that shouldn’t be found written.

A-holes!


#15

give me a call when xp is on it and if its good or bad.


#16

Hi Tobbe

Are the harddrive drivers the same on all machines?

Just a thought…


#17

yup they are

exept the ones that the burner did it good on they had different drive’s but they where different models either.

the problem leis in the hp machine’s


#18

Harddrive drivers?? U mean if the hdd’s are the same in all machines…well in my 6 Hp Vl800 they are…but in the other machines there are different kinds of hdd’s.
However I have updated the IDE drivers for the HP’s but with no luck.
Also in the HP’s the drives are 7200 rpm…and in some of the others there are 5400 Rpms…

Theres something fishy here!


#19

I mean if you are running the same version of Intel Application Accelerator on all machines.
Are the Bios settings for DMA the same?
Are you using same IDE cables on all machines? I think I´ve heard something about troubles when using the new (80?) IDE cables with Plex.


#20

I mean if you are running the same version of Intel Application Accelerator on all machines.

reply: Not using the application accelerator. Only Chipset and IDE drivers. Don’t think the accelerator is part of the problem.

Are the Bios settings for DMA the same?
Reply: Yepp!

Are you using same IDE cables on all machines? I think I´ve heard something about troubles when using the new (80?) IDE cables with Plex.

Reply: I use 80 pin cables in all machines…and they work in every single one but the HP’s.
