While I cannot speak for all Sager users, I personally have no qualms whatsoever in helping aid a Dell user, and would think most other Sager users have a similar sentiment.

Unfortunately, I do not have access to an NP9880.

Ok. I *might* have a modified bios for you. There is only 1 problem. I was looking at the files Joker sent from the author of NiBiTor and I noticed that, in addition to the core and memory values, the last byte(bit?) is also changed.

I compared my original 6800 Go bios with the modified one I made with NiBiTor and it also had the last value changed. However, when viewing the hex in NiBiTor, the last value doesn't change when you edit core or memory values.

This leads me to wonder why the last value is changed at all, if it is even intentional. If Joker can get ahold of the author and find out why, it may save us all some grief, but failing that, I'll hand edit just the core and memory values for my bios and try to flash. I'm pretty sure I have a good recovery plan if it kills my card.

~Change bios boot settings to boot from CD first.
~I won't have any display, but it should still boot.
~Wait like 5 minutes so I know I'm at the R:\ prompt.
~Blindly type nvflash c:\orig6800.rom.
~Pray.

I'll let you know. I want to try it first before I post anything.

Could that last value be where the clocks are locked?

So why in the hell would editing your BIOS increase you clock speeds?
Are you saying you can go up to 1000Mhz on memory on 6800 Go DDR1 NV42 when reflashed the BIOS?

From what I gather, the sager guys have modified the Nvidia bios to gain performance on their 6800 go cards. I have done this with my ATI cards in the past after many people had perfected the procedure. Mad props to those lab rats with balls enough to try it!!!!

I believe the procedure (if successful) may unlock the video bios, which may in turn allow the card to be clocked higher than the current locked values.

(although I could be completely misunderstanding the intention)

Did they change timings or what? Should I use the SAGER BIOS then?

I am just lurking at this point. I, myself, wouldnt try this till a few more peeps are successful with verified performance increase.

I'm not too crazy about that bart thing. I was kind of curious if I just used a DOS boot CD and stuck in a spare blank laptop drive (I have a 20G that I use no more sitting around).

I doubt it. It's possible, but:

On the stock 6800 the last value is A6 which translates to a signed byte of -90 or an unsigned byte of 166.

On the NiBiTor modified 6800 the last value is 1A which translates to a signed or unsigned byte of 26.

On the stock 6800 Ultra the last value is 61 which translates to a signed or unsigned byte of 97.

On the modified 6800 Ultra that Joker provided us from the author of NiBiTor the last value is 8C which translates to a signed byte of -116 or a signed byte of 140.

Here's an example of what the end of the file looks like. The last 2-digit hex value is what changes.

00000000717171717171717171717171717171717171717171717171717
17171717171717171717171717171717171717171717171717171717171
71717171717171717171717171717171717171717171717171717171717
171717100FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF8C


Playing with this data between the 4 files, I see nothing that would indicate a boolean flag for locking or unlocking OCing. Of course, it might not be boolean.


When I get home from work, I'm going to see what happens when I try to flash with a rom that hasn't changed the last value. If it works on my 9300, it will be worth trying on the XPS.

Every one interested in getting the bios from Sager dudes chip in a buck to someones paypal account (we need a trustee to hold the funds) and then that person can make an offer to pay one of the Sager dudes for their time.

Can you afford a buck?

I could afford a few but why. If the person is an enthusiast, they would do it for free. If the person wanted money for it, they are a person I wouldnt want to give money to in the first place.

Alright, I chatted with a friend today who pointed out that being at the end of the file after a bunch of obvious filler, it might be a value meant to pass a checksum. I checked this possiblity out, and indeed, my 6800 Go bios and the NiBiTor modded one pass the checksum because of the final value.

I looked at the files Joker provided, and they didn't pass the checksum. For the original the checksum-16 came up with C700 for the original but C800 for the mod.

I have created a modified 6800 Ultra bios with a 400/1000 setting that matches the checksum of the original. Who wants to try it?

By the way, make sure the sagers have the same memory as the xps2.
If it doesnt you can be sure to get artifacts at the least or a non working vid card at the most.

Are the 400/1000 bios overclockable? Although I think getting the sager bios is the safest bet...

RamIt, the sagers are 256mb cards and I am pretty sure that they have the samsung 1.6ns memory as that is the only memory I have seen used on high end cards spanning from ATi to NVIDIA.

If it is, isn't manual overclocking possible with a little registry fix with Coolbits? Or is it crucial that you have to do this bios thing?
