My Ati X800 Xt/pe Getting Modded:

[Jojo1971]

I finally decided to try the "pencil mod" from VR-ZONE.com) ...Im using the stock HSF... Im using a Digital Multitester to measure Resistance and Voltage.


*default voltage: 1.405 @ 416 ohms
idle temp=55C
with load =75-85C
max stable CORE: 530
-------------------------------------------
**after the mod: 1.64 @ 357 ohms
idle temp=65C
with load=95-105C
max stable core: 600 (so far).

Now here's my question: is 1.64 volts too high and dangerous? Should I lower it or go for more? I would like to stick to aircooling as much as possible?

After determining the "maximum safe value" (resistance), Im gonna replace the pencil mod with a Cermet Potentiometer.

Then after doing the CORE MOD, Im gonna proceed to the VMEMORY MOD, Then to the OVERCURRENT MOD.

Again I need advise regarding the voltage: Any inputs?

Dont Touch That Thing!

GET MORE COOLING! That thing can roast anything @ 100c!

STEP AWAY FROM THE CARD! WAY TOO HOT!!!!!

 

[Sentential]

Yikes! Im suprised it held up that well. I hope the diode is wrong

 

[Jojo1971]

i cant use my REV. 3 VGA silencer..the round thing that touches the backside of the card is bigger than the "free space". i could possibly break some tiny resistors while tightening the screws..

is it time to watercool?

now, my x800xt now feels as hot as my 9800xt...

*Points 3030R6 with scope to jojo's head* Son put the pencil down and walk away from the card..now!

It's time to lower that voltage. And yes I would recommend watercooling. I have my X800xt at 1.88 core voltage and it doesnt get any hotter than 38.

*snif snif* what's that smell?

I hope that diode is off. Your card is blazin hot! You can boil water on that thing. Nice overclock, but don't kill your card.

Uhhh...makes perfect sense, that's .25v (18%) increase on the stock cooler! Either beef up that cooling or remove the mod.

My 9800 can't even take it being .05v above stock on the stock cooler.

 

[Jojo1971]

okay im gonna lower the voltage...so what is considered acceptable max temp with stockcooling to you guys? any inputs?

I would leave it at stock till you get some better cooling.

Agree. Just invest in a VGA Silencer. Aren't they like only 20 bucks anyways?

 

[Jojo1971]

okay guys ill listen to you..im gonna leave it at default for now while looking for WC parts..thx ...

If the old blocks fit the new cards, the fusion HL has my recommendation. It can be used with pure water (no antifreeze) in an all-copper system, and it cools like a white water is bolted to your GPU.
