I’m needing some help in solving my buffer underrun issues with my Plextor 716A drive (bios 1.08).
Here is my configuration.
AMD 3200+ (Venice)
MSI Neo4 Platinum SLI (bios 3.00)
2x250 Maxtor Maxline III SATA on NVRaid 0
OCZ3200 EL Platinum Rev 2.
The system is OC to 2.7Ghz (270x10) on 2.5-4-3-8 1T, 1:1
ATI X700Pro 256MB
Antec TruePower 2.0 550W
SATA, PCI Spread Spectrum is disabled.
What’s happening is BPRec will kick in at least 10 to 20+ times during DVD burning from 4X ~ 16X. I can hear the drive stop, wait for the software buffer to fill up and then spin up again. The drive buffer also drops to 0 after the software buffer refills, but refills very quickly. I’m using FujiFilm TYG02 discs rated at 8X but burns at 16X (Avg 11X) and some generic cheap discs to test 4X.
This drive is an RMA drive from Plextor with manufacturer date of Jan 2005. My original drive died
I’m running WinXP SP2 with Nvidia SWIDE drivers. DMA mode is set to Ultra DMA 66. The problem also exists with standard Windows IDE drivers set to Ultra DMA 66. WinXP is a clean install, nothing installed except for some system monitoring/testing tools such as CPU-Z, Clockgen, Plextools, Nero etc.
This is not an OC issue as I have resetted the bios to factory default and the problem still exists.
I’ve ran the Plextor self test and the test passed.
I’m almost out of options. I have not yet increase the voltage to the NB chipset which may increase the stability of the SATA devices. (I’m doubtful on this one)
I have not upgraded the bios yet as any update from 3.00 will not allow me to OC to 2.7Ghz…
Nero’s Burst Test worked once with this drive and the result was 44MB/s. other times, nothing shows up (Nero software bug with Plextors?). The Pioneer I have in this system is reporting 24MB/s.
Any ideas/solution? Does anyone else have this problem?
