Help me tweak a new PCI-E 6800nu

[Mustanley]

Got a new Dell (don't laugh) and have some questions regarding the PCI-E 6800nu that came with it. Specs on the machine are as follows
P4-3.4GHz - Alderwood chipset
1 gb 533MHz DDR2 ram

I was trying to unlock the extra pipes and vertex unit, but I'm having trouble using the guide from Rivatuner. Here's the output from the Rivatuner diagnostic report. Why does it say the memory bus is only 128 bit? I thought all 6800 were 256 bit.

I think the original driver was the 66.72. I ran 3dmark03 and got a score of 8,077. I recently installed the beta 70.90 to continue testing. Any help on how to unlock the extra pipes and vertex unit? I'm stuck on line 7 of the Rivatuner readme 6800 softmod section where I'm supposed to find the "SW units masked" line from the report. That line is not showing on my report.

Well, I have at least tried overclocking this card and it seems to be clocking pretty high. I don't really have a point of reference since I don't know how well others are doing with their 6800NUs, but this one will do 430 on the core and 850 DDR memory with no artifacts (stock is 325,600). Got a 3dmark03 score when overclocked 10,144. This card uses the nvidia reference cooler btw with no ramsinks, so there ought to be some more untapped power left in it if I can get some good aftermarket cooling on the gpu and memory. Just wish I knew how to attempt unlocking those pipes and extra vertex unit.

Its available in the newest version of Riva Tuner.

I thought I had the latest version, downloaded from guru3d.com earlier today. I've got v2.0 Release Candidate 15.2
Is that the latest version or not?

[Spyd3r]

Yep the magic version's the 15.2.

I'm not getting any disabled pipes or vertex units.
