1.42v - 600mhz (stock V)
1.51v - 635mhz
1.60v - 660mhz

Mmmmm, what ya got cooling that baby

Very nice dude :thup:

I see you found the resistor you were looking for

AC

Yummy

I just had mine modded, really a great upgrade for those thinking about it. I'm pushing well over 1.6v though. :thup:

bobmanfoo · Feb 21, 2005

whats the max safe voltage?

edit:
oh yeah, when does the ovp kick in?

Under my water, i've had mine up to 1.8v+ while benching, staying under 32C. I run at 1.7v for daily use, temps are still only around 28C. When i bench i'm at least at 1.75v+. I think most would say somewhere between 1.7-1.75v would be "safe" for water under daily use. I always push my hardware to the max, i've been lucky so far

ovp around 1.9v i think? I know on mine it didn't need the ovp mod, it would hardlock before it reached that point.

my load temp is 49C w/ 1.6v :-/

what woud you recommend max 24/7 voltage?

edit: load temp at 1.6v is 52C, 1.7v is 55C.... back up to around stock cooling and volt temps

Sorry, i was stating idle voltages. My load was still under 40C though, i'll look into that for you later.

If you're happy with your clock, i would just leave it. If it were me, i would pump at least 1.7v into it. If nothing else, at least test it, see what kind of clocks it will give you. Even 1.65v would be more than safe for decent water.

bobmanfoo · Feb 21, 2005

hehehehe...be right back

edit:
doing 680mhz 1.7v woooooot

k thats enough for today, gunna run 1.6v 24/7, 650 on the core is plenty fast

Sucka · Feb 21, 2005

lol....nice.

Pump a little more in there for daily use, plenty safe

stockhatch · Feb 21, 2005

Dang. So close to 700 and you're giving up? Hehehe. Listen to Sucka...stop screwing around and put 1.9v through it

Seriously though, nice OC :thup:

bobmanfoo · Feb 21, 2005

man i ill try to hit 700mhz stable sometime, im sure its possible

Copkiller · Feb 22, 2005

I wanna voltmod my Powercolor X850XT to!! =P
How?
Can somebody help me with a good guide to my card?

Thx

Edit: Found it in the forum....hey..sorry! :beer:

But I don't think I can do it anyway...I think I suck in this... :bang head

bobmanfoo · Feb 22, 2005

no guide needed really, just solder on a 10k or 20k ohm VR to the two blue points, before powering up make use that the VR is set at max resistance, it might be a little hard because the area you are working with is extremely tight

Did You Try 1.9V @700mhz

Ad Rock · Feb 23, 2005

You need to get a peltier on that card and really let those clocks fly. That is one sick card you have there man.

That was actually a poor attempt at humor on my part. I would never recommend actually putting 1.9 volts through the core on that card. Im pretty sure bob understands that.....I hope hehe

bobmanfoo · Feb 23, 2005

lol, i might be a little crazy but im not that dumb, 1.9V on my dinky WCing will never happen, im pretty sure it will crash anyway, maybe when i get a pelt like AdRock said i might give that a try

Blackmage · Feb 23, 2005

Hey...Did u at least try 700mhz?
