Overclocking your X1800XT
Using ATI Tool
Published: | Source: Overclock3D |
What do they mean? In order from the first reading to the last..
- Voltage Regulation. This temperature monitors the VREG area. This is near the rear of the card, around the long pink/red heatsink. Try to keep this under 75ºC. You can lower temps by placing a 120MM fan at the rear of the card.
- Core Draw (Amps). This tells you how much power your core is drawing. X1K's draw a crap load of power, so expect this to be quite high at times.
- Fan Speed. This tells you how fast (in percent) your fan is going.
- Core Temp. This is your X1K's core temperature. Make sure this does not exceed 80ºC at any time.
- Ambient Temp. This is the temperature of the air around the video card. The sensor is located towards the front of the card, by the DVI plugs.
Now that you have proper understanding of the temperature readings, it's finally time to overclock.
Note: Do not adjust the sliders when the 3D View, or Artifact Scanner is open. It will most likely lock up your computer.
Simply adjust the bars to your liking. Drag them up 10-15MHz at a time, and open 3D View for about 2 minutes to test general stability. Fire up CS Source, or another game you like to play. If it doesn't freeze within 20-40 minutes, you're all set! These cards are very sensitive, and they WILL lock up if you OC too high.

Those are my stable clocks on this Zalman VF700-Cu. I'm sure I could go higher, but there really is no need at the moment. Note that these cards draw an outstanding amount of power. Single rail (+12v) PSU's are preferred with X1K cards, in most cases. If you have a dual rail PSU and your card is unstable even at stock, investigate a bit. Check both of your +12v RAILS with a Digital Multi-Meter. You can get a DMM at your local Radio Shack for $19.99. If your rails sag a noticeable amount (under 11.80v) under load, you either need to adjust your rails via pots if your unit has them, or you will need a new PSU.
If you're lucky enough to have a Tagan PSU with a switch on the back, to select either a single 12v rail or dual 12v rails, slide it over to a single 12v rail.
Here are my voltages (idle, 0.03v less compared to my DMM)..

Per normal, always take caution when overclocking. Please take note, that these cards have been known to lock up and send the monitor into standby mode when the core is pushed too high with too little voltage. So, if you're OC'ing and your computer freezes, then your monitor goes into standby mode... do not fret. Just press the reset button on your case and you'll be back up as soon as your computer boots up again.

Well the cards you are comparing are not even in the same group as in price or performance wise. So it really depends on how much you want to spend. As XFX 7800GS AGP costs around £220 and Ati X700 XT versions around £70 its completely different league.
Ati X700 XT has similar performance to Nvidia 6600GT.
I know you said you dont want to change the motherboard. Considering you have A64 processor changing the motherboard will allow you much better options in GFX cards and for future compatibility.
You can buy 1 of those ASrock 939 motherboards , costs around £40 and buy a Ati X1800XT 256 mb version for £200 so total cost to u would be around £240 where as with XFX 7800 GS still costing you around £220/£230 with no future and you should get better performance with Ati x1800XT.
So it truly depends on your budget.

lx700 there was a sapphire version of it
, yeah i will get a new pc next year so all i am fdoing is getting more ram and a gfx card nothing more , next year i will invest LM2000 in a new pc 10x for the help i decied i l go for the nvidia

Yep go for the nvidia card - much better :)
10q i will do that + i will getting another 1GB ram thankyou for the help
got it does it support HDR?
yes, most deffinately lol
10q i love direct x 9 i pwns in cod 2 with the reflection + in CS : s the scope reflects
Nice card lim, you'll be happy with it I'm sure. What RAM do you currently have and what new stuff are you looking at getting?
i got with the gfx card a 1.0 gb ram now i have 1.5 gb i think i will leave the pc like it is
CSS Valid
Thanks for the help.
