X800 XL OCing Questions?

[imported_Noob]

The X800 XL has 11k or 11ns (whichever) as opposed to 13k like all other X series cards. Wouldn't this make it better for OCing because less electricity is used? Like a Winchester 90nm Athlon64 design instead of a 130nm design?

That is because it's low 13k, and normal 11k

also, it is reaching it's max power useage. also it's called low dielectric 13u instead of normal 11k i believe.

I think you might mean "110nm" and "130nm" there.

The 90nm A64s also use SOI (Silicon-On-Insulator) and strained silicon technology, which is mostly why they OC better than the 130nm models (it's also a bigger jump down, obviously, from 130nm->90nm rather than 130nm->110nm). ATI was able to lower heat output and power usage on the new process (as well as increase yield thanks to the smaller cores), but didn't get very high clock speeds out of it.

The X800 and X800XL also run at a lower stock GPU voltage than the X800Pro/X800XT. Volt-modding apparently helps them quite a bit (although it also dramatically increases heat output, and is not for the faint of heart).

Do you mean it's sorda in between. Sorry I'm quite noob at this (hence the name). I just look at benchmarks usually to determine which is the better card.

Volt modding helps the X800 XL not stay as low in VPU speed, but increases heat output at the same time? Is this why it's not as cool?

you should really get water cooling if you really want to voltmod.

What causes a lower nm design to run hotter and therefore needs to have it's VPU speed decreased?

I know all about those.
