This post completely changed my understanding of memory when overclocking. Essentially you have saved me from having to buy some god awful expensive ram and I thank you for that.

Same here on the liteon drives. I just pulled an old Liteon CDRW drive I had in my Athlon XP rig (LTR-52327S to be exact) and connected it to my current rig and got the same reboot thing. I tried the LiteOn dvd burner I purchased in the athlon XP machine and had no issues. I know there are plenty of others around here who are using Liteon Drives in conjunction with thier DFI boards which is why im a bit confused on this one. I guess the next step would be to RMA the board itself since ive tried both the firmware and RMA of the drive. Is this best done through the folks I bought the board from (Newegg) or DFI?

The only settings I wasnt sure about when turning on the spread spectrum relating settings were the Errata 94 and 123 settings which I left at disabled and enabled respectively since thats what they've always been set to. Based on your response its looking like this is a lost cause.

My first jump to A64 was using a DFI board. About a week or 2 after putting the system together successfully I purchased my first DVD burner (a Liteon SHW-1635S to be exact). When the windows splash screen comes up with the little animated bars I see a brief flicker of a BSoD and the machine reboots itself. There was a few occasions I was able to get into windows but upon inserting any media into the drive the pc would reboot. This behavior continued even with the computer in safe mode. My system specs are listed in my sig and I have tried the following things to get the drive to work: Tried both the primary and secondary IDE channel. Tried the drive with the jumper in master, slave, cable select and completely off the drive. Tried reinstalling the nvdia chipset drivers from the website (version 6.70) Tried the system with both the nvidia SW ide driver installed and not installed. Tried a windows repair install and eventually a complete lowlevel reformat and reinstall of windows xp professional. Tried updating from the stock bios to the 6/23/2005 bios on the DFI website. Tried updating the firmware of the drive to the newest one Liteon has available. (I got lucky and managed to do this w/o the computer rebooting on me) I talked to a Liteon engineer over the phone who guessed that there was either something about the nvidia chipset driver or the motherboard bios that was too aggressive and causing the computer to reboot. I tried the drive in a few other machines and there was no problem. I also tried a number of optical disc drives in conjunction with my DFI board and did not experience this problem. I eventually sent the drive back to newegg for an exact replacement believing the drive to be faulty. The replacement drive is exhibiting the same behavior. I have tried the following extra measures with the replacement drive. In the bios under the IDE settings I turned off UDMA on both channels and manually set the channels to mode-0 from automatic. The other 3 settings (DMA Transfer Access, Prefetch Mode, HDD Block Mode) in this same section were all set to disabled. The drive rebooted itself as always. Believing that the issue was caused to some kind of EMI (the case being used is an open workbench style case) I turned on all of the EMI related options I could find in the bios section. Again the drive exhibited the same behavior. Also with the drive removed these EMI options (CPU, SATA, and PCIe Spreadspectrum) caused my Belkin Nostromo N52 pad to exhibit very weird behavior and eventually had to be turned off. The rebooting ceases once the drive is removed. Is there anything else I can try to try and get this drive working?

Has anyone recently tracked down a place that still sells the Leadtek bridge or come across another bridge that will work with an Ultra-D? I tracked down this one that Monarch sells: https://www.monarchcomputer.com/Merchant2/m...uct_Code=270125 The center area appears to be made of a flexible material which would presumably make this quite handy. Would this bridge work for a Ultra-D mod or am I going to have to keep looking out for a Leadtek bridge? *edit My system specs arent in my sig because I havent ordered my rig yet from newegg.
