Also fast writes and sideband addressing, hex adjusting?
This is for that crappy bfg.
Its system is

Custom power supply I built 450w
MSI 6380LE mainboard
3x buffalo 128mb pc2100
AMD thunderbird 1.4 (not oc'ed)
cheesy compusa generic heatsink/fan
80gb western dig hd
lite-on cdrw
1.44 floppy
2 cheesy case fans
cheesy case
Its a cheesy system, well deserving of the cheesy bfg card. lol

As for the leadtek I probably wont touch it.
I am EXTREMELY satisfied with it.
Gonna play around with stock bios on bfg, if I cant
get decent oc from it, I'll try the ultra bios you recommended
but for now gonna see what I can do with stock bios.

BTW how did the hose work for you?
I like the sheer black :-)
Although I believe temperature is a the main ingredient for triggering the throttling function, I think it is more complex than just a temp threshold ? It is more likely to be at least a combination of both, temps, and a designed in set of conditions measuring the GPU's/Memory's ability to process data for given speeds of operation; a power throughput level if you like ?? A safety condition set either by Nvidia or the designers of the cards. And if so, then throttling can happen even when temps appear to be reasonable, simply because the bios/driver deems it not safe for the GPU/Memory to process at the level being asked while running at whatever speeds and/or temps prevail at the time ?

However I think it not unreasonable to assume that although throttling being a safety function could occur on all cards at any time, it is likely to happen less often at reduced speeds and/or when temps are kept down ! So, if throttling occurs, then just either reduce, GPU and/or Memory speed, or, temps, and it will stop triggering ? But also remember to reboot, to reset the throttling function !

And, barring info being available direct from the designers of the card, only experience over time will support or refute this belief ?

Apart from the above, your only other recourse with throttling is to set it same as 3D, so that if triggered it wont change GPU speed ! However most important you also set throttling GPU volts to be same as 3D GPU volts !!! Otherwise GPU speed may drop back just because not enough volts to sustain required speed ?

EDIT:

haven't purchased my hose yet !
