Volt-Modded my X850xt... PICS

[TheMaster]

So i was bored.. and decided to volt mod my x850 xt using the VID mod from the TechPowerUp! page.

First, the disclaimer:
If you want to volt mod your x850, only do so at your own risk!
Make sure you have a backup video card, and are willing to lose it.


Ok lets go,
I used the VID mod to adjust my vcore from 1.4 to 1.5.

(Use the table from the link at the bottom to determine which resistors you need to adjust)

I went to 1.500 V so:
First, i used a pair of surgical pliers to crack the R1855 and R1856 resistors .

( I didnt really think about it and cracked resistor R1858...:roll: )

Then i used 2 old 1K resistors and soldered them into the right spots to give me a core voltage of 1.5 volts. If done correctly, (ie not cracking R1858) you'll only need 1 1k resistor.


Here's the first one:

Both resistors soldered into place:

And done!!

With the stock cooler i bumped up the core to 613, and it hovered around 70 degrees. I'll be ordering an Arctic Silencer 5 soon to mod it further.

nice work my friend...........can we see same results?........
did you still used the air cooler....?
how high are your voltages now...?

:lol:

 

[TheMaster]

Yes, its a stock cooler! And im proud it. :lol:
If you have a good chip and properly mounted cooler you should get similar results.

I Increased the voltage from 1.40 --> 1.50 V and got about ~ 615 Mhz.
(Ati tools freezes at 620 )


Once i get my AC silencer and some ramsinks i'm going for 700 on AIR. :twisted:

the overdrive utility also does a good job.......i use the stock cooler also and i get between 35 in idle and same 65 in full load (for at least one hour......)....in battlefield 2 1280x960 aa4x af16x all details to the max....in got same 63,4 degrees after few hours

it seems that the stock cooler does a very good job......

good luck my friend

Those wires are quite long.

 

[TheMaster]

Nahh its all Digital. The chip actually controls the voltage, i just changed the input parameters to a higher setting.


Your method is a lot more eye pleasing though, but i would keep on cranking that voltage until my card'd burn up :lol:

I could have probably soldered a switch to all those contact points on the chip and made an adjustable voltage regulator.

Looks nice, what are you benchmark scores with the card now?

 

[fainis]

ya ..we demand ..benches
i mean what`s the purpose of all this ..oc-ing and moding if there are no benches

Exactly
