How safe is vagp overclocking?

[Canterwood]

Hi all,
I'm currently playing around with some overclocking on my P4 2.4C.
I can hit 3ghz with it no problem (250mhz x 12) and have just purchased some GEIL Ultra Platinum DDR500 memory.
However to run the cpu and memory 1:1, I have to up the vagp voltage to 1.7v.
How safe is this? Can I fry my video card?
I have a GF4 Ti4200 atm, but am getting a Radeon 9800 Pro next week, and I don't really wanna damage it. (not yet anyway) 😉
Thx.

just try to keep the agp voltage at stock when you try it with the new card.
agp voltage nevar did anything for me....i even upped to see if it would make my OC of my 9600pro stable

What speed is your memory running at?
At 5:4 ratio, I can overclock to 3ghz without changing any voltages, but 1:1 the system wont boot without the vagp @ 1.7v
I will try the new card at stock voltage though, but will it be damaged if I have to overclock the voltage?
It will be an agp 8x card, I think they run @ 0.8v as opposed to the 1.5v the GF4 runs at currently.

my mem is at stock speeds and my OC is at 3.0 right now
upping rhe voltage on the agp like anything should shorten life but iono by how much

you try upping the voltage on the cpu and mem instead of agp

Safe??? I know it is almost an essential when ocing the p4 systems cause the northbridge chip's vcore is also set from that.....I have ran my last 2 p4 systems at 1.6v-1.7v for over the last 1-1/2 years and my radeon AIW 8500 is still fine....

does it make a difference on AMD systems?

Aye. I have never heard of a video card being busted from the Vagp being raised.

Thanks guys, I haven't overclocked that much till now.
I'll keep it set at 1.7v.

Upping the vagp voltage won't help in getting a higher overclock but it will make the overclock you got alot more stable.:beer:🙂

ATI actually supports upping the vagp on alot of the R300 core cards. I run my 9500 pro at 1.7 never had a problem

do you got a link to this? i'm just curious because i want to run my agp voltage at 1.65 (its currently at 1.6v) for more stability...

you positive you cant fry a video card at 1.65v?

I don't have link but they(ATI) were telling people who called customer support to do this. I ran mine at 1.8 for awhile, but it was stable at 1.7 aswell. so I "think" it is pretty safe.
