Find Max until crash, plus other Q's

[jane911]

Hey all,

I have a Sapphire x1950 gt or xt, something like that.. anyways,

I ran ATI Tool, and hit Find Max Core, it goes up until my system crashes/reboots itself.

So, I went up in increments - but I am unsure what is safe or not for my system.

The stock is 513 and I put it to 540, idles around 50-60 and during 3d games can go up to 80-90

The memory was increased from the default 640 I think to 680 or something.. but I am still unsure what is safe or unsafe, since I am doing it manually... Also sometimes when I move the core slider up, it will go back down to where I moved it from and not change ... it took me 3 or 4 times moving it to 540 from 513 until it actually stuck..

I have 2 side fans in the computer, one in the back, one on the chip and the stock cooling on the gaming card..

anyone shed some light on this?

RTFM.



Without a understanding of how the X1K series cards overclock and control fan and voltages you are better off staying at stock.




So no bad intentions, but please read up before you start, or be ready to buy another card.

So, I guess that means 'No, I can't shed light on this for you' - So, the manual will tell me how the x1900 GT works in terms of compatibility with ATI Tool?

Thanks, I think.

If you "need" to tune your card (as we all feel the need for speed), first turn fan speed on 100%, after that, manualy move sliders for some 5 to 10mhz up (not like you did first time). Chk with scanning for some 10-15min then go on. Chk on 1900 thread but don't go str8 for that clocks and play safe.
Scream if you wanna go faster!

Manual find max core and mem is better than auto find max core and mem. Do not run find max core and mem (auto or manual) without you beside computer.
