AGP voltage question

[94transam]

No one replied to this in the OC forum so i moved it to here

Hey guys
In trying to get my fsb vs. multipliers sorted out i got stuck at 14x155=2170 as being the most stable. That ran a 13399
but thats not good enought for me.
%50 of the time i run at 13x166=2166 i get lockups during 3dmark, but the other %50 i get 13880. not bad.
Also a higher multiplier than 14 cause my computer to not post and a higher FSB cause quicker lockups during 3dmark.
so i decided to tackle the higher fsb problem. I've got my vdimm at 2.75 and i've moved vcore up to 1.85 and back to no avail
so now i set my agp voltage to 1.7 and i seem to be running pretty stable at 13x166=2166. my next step would be higher FSB settings and/or lower multipliers. Maybe even bring the agp to 1.8 if needed

My question is whether 1.7 is safe with a factory radeon 9700 pro. I have two rear exhaust 80mm's and one side intake 80mm and a triple 40mm hd intake in front.
Also would 1.8 be pushing it?

Thanks in advance
Rob

ok, some theories. i think AGP voltage in the mobo bios does not give your vid card increased voltage. i think it gives more voltage to the chipset, thereby increasing fsb overclocks. the vid card is geared to get 1.5v. that's it (agp spec). you can give your chipset more voltage, to ensure that your vid card really gets 1.5v, but it won't get more without messing with the card itself. think about, who has gotten a higher overclock of their vid card with the agp voltage of bios?

here is where i got my info:
