Radeon X1800GTO@XT MOD (12P to 16P)

[ganescha]

ok, i got my card today and flahsed it with different bios i got from aorund the web, didnt unlock my sapphire.. to bad. but no worries lets clock this bastard. Firts of, how can i get the GPu temp etc in ati tool to show? only time i got it was when i flashed it with sapphire xl bios.
should i go for that bios then? would be nice to se temp and volt etc.
i have changed the volt to 1.38 now a clocking, but the thing is when i use ati tools scan i get arty even in deafult but non in ati tray tool.
help please.

Yeah, I get artifacts in ATITool also with my GeCube X1800 GTO @ stock, is this a normal thing? Would be good to know cause I'm on to the lowest on web support peeps about it and am trying to figure out if I should have the swap it out.

 

[chron]

If my card was showing artifacts at stock everything I'd send it back and get a replacement. Thats horse shit.

As for the other guy with the temperature readings, download RivaTuner and it will show you.

in ATI tool-settings-Artifacts scanning-use old scanning method.
ATI tool is very bad compitble with GTO cards, just use old scanning method and it will be allright. When i used XL bios everything was allright, but workes crap with GTO bios.

 

[wolfblitz1979]

Thanks for the info, works ok with the old method, only one small artifact in 5mins and that's probably heat related I would think but will keep an eye on it

 

[ganescha]

yeah maybe, have you changed the bios? is it orginal one on now?

 

[wolfblitz1979]

Yeah it's the original bios, haven't tried flashing it yet cause I'm not too sure on the best method to do so and don't want to screw it up lol

 

[chron]

I got no artifacts with my HIS and I changed no methods

 

[ganescha]

well you flashed yours with XL bios or a modded one, maybe thats the thing. I have flashed mine now so i can change volt control etc. in ati tool. But no mather how high i change it i get lock up at 565 at core.. i can go 640 on memory in stock volt.
maybe ati tool dosnt change my volt on the card?

 

[chron]

I modded my bios with a hex editor to unlock the four pipes. The xl bios makes it seem that you can control voltages but you really arent. My suggestion is to make a copy of your origional bios, open it up with a hex editor and at line 00000070 find the value "19" and change it to "18." Save it, then open it with RaBiT2.0a. You can set voltages depending on what kind of cooling you have. At 1.2125V 600/600 was easily obtainable with stock cooling. I've since then gotten a VF1-Plus and 80mm case fan to keep the card cool. V regulators idle at 50C at 1.45V which is very good. At 700/700 my core idle temp is 45C, not too shabby.

 

[wolfblitz1979]

nice temp chron, my gpu idles at 56C...is that about right for stock everything or too much?

 

[ganescha]

hmm.. ok, i did it like i got from a another forum.. you now the one with bat file etc.
so i have my orginal bios but with volt control, but i dont now if it works. I tested your guid wit h rabit and i set the orginal bios to v 1.3 but i still got lock ups in 560 on core, i havent done the HxD thing, isnt that just for unlocked cards?

 

[chron]

HxD thing is a hex editor. Any hex editor will do. And changing the value in the hex editor unlocks the pipes yes.

Ay 1.2125V I can get to 600/600. I'm thinking the reason you get a hard lock is because of your power.

What size power supply are you working with? Also, what brand of card is it?

 

[sleepeeg3]

^ Those were my exact clocks on my HIS card. It could also do 625|625 (25% OC), but temps on the VRM were scaling above 80° so I called it quits.

Agree that power is another big issue you guys should be worried about.

 

[chron]

well dude, all it takes is an 80mm case fan and some bread ties and your golden...
Here is mine: I have a squirrel cage fan that rests above the heat sink.. It works great

 

[ganescha]

yes, now when you say it you are right.. changed the volt to v1.26 and got it up to 575/620, with higher volt it just locks for me.. so it must be the PSU. Ordering a new one now.
Btw, got 7955 in 3dmark05 with that clock. just have to sit and whait for the new PSU then.

 

[sleepeeg3]

Nice! Now that is a two slot cooler. Was it tough to mount that? Man I should have jury rigged something like that with a large blower to exhaust the temps from my ARIA.

I probably will not finish my VRM sink until the weekend or more.

Tough to diagnose a power issue, but if you overclock the GPU to the max you have problems and then add on an overclock of the RAM, you might see crashes more frequent. Another card I had would get crashes and system lockups @ 700, no matter what voltage I used and mem seemed to aggravate it. Problem is there is heat sharing between mem and GPU, so that makes it difficult to troubleshoot.

 

[ganescha]

what driver do you use with your card in bench? i use catalyst 6.3 still. have tried Omega driver based on 6.3.

 

[sleepeeg3]

I hear 6.5 gives some gains over 6.4. I don't know how it compares to 6.3. Just use the latest. That's honest.

 

[ganescha]

update: got 580 on core now and 625 on mem, artifact free, i get 7960 in 3dmark05 with catalyst 6.3 and 8016p with catalyst 6.4, im just whaiting on my new PSU that comes to morrow so i can clock seriously. volt is on 1.125 on core now, cant get higher with this crappy PSU!

 

[chron]

 

[ganescha]

very very nice man.... how many volt on core? on mem? what drivers do you use and what CPU do you have, how about 3dmark05?

 

[chron]

6.5's, 3GHz Intel w HT (my bottleneck), 2gb ram, 1.45V core 1.9V mem (I think)... I am unable to modify mem voltages

 

[chron]

you can see on the cpu score in 3d mark 06 that my cpu only got a 900. I think an fx57 gets like 1940 so I think either an intel conroe or an AMD am2 socket cpu will be my upgrade later this summer since both use ddr2

 

[chron]

heres a video stress test *only*... You can see how it compairs to a stock xl:
