it dosent matter how much Ampere (electric current) it is.

the important thing is the Voltage (volt), if you use a PSU with wrong Volt, its bye bye with your laptop.

you can read here on this forum when they change a go6800 (Dell 9300) to a go7800gtx and also change 90 W to a 130 W. works perfect.

did you actually already apply it? if yes, did it change the core temperature?
and do you have a single- or a dualpipe?

I have a single pipe, I over clocked it with the 1.24v bios mod to 600/740 and seems stable running in bioshock using a 90w psu. I only played for about 20 minutes because i don't want to overload my 90w psu. I already ordered a 130w even at 600/740, bioshock still doesnt run very smooth at at 1024x768 with shadows off, global lighting on and real time relfections off, everything else on high... i think i should just get a 7950gtx if i want any kind of smooth gameplay... in cs source i get jumps from 30fps to 70fps, avg 40fps with everything on high and native res 1440x900 also my gpu temperature hit around 90c - 95c in bioshock... is that going to cause a problem in my system in the near future?

the question was actually going to svärige, but nevermind.
if you ask me, more than 90 degree is not good.
as for me i am around 470/680 1V and can play bioshock
(the demo) with everything on high (but global lighting on)
at 1280 x 800. i stay about 30 fps and the temp never get
higher than 83.
i'm not an expert, but i think if you're running a singlepipe
7900gs with 1,24 v and want to oc that high you need the
130 w power supply as well as some good cooling method.
that's why i asked sväreige, because in some post he stated
something like "the 130 w power supply keeps the car cooler"
and i would like to know if i got him right. that means, if he can
really oc that high while staying at 75 degrees while playing
only by getting the 130 w thing.

I am getting severe artifacts when testing
in which game? what kind of artifacts?
Quote:
relatively safe frequency for a 90w PSU (460/680)
if these are really artifacts and they appear in different games you should try lower clocks
and the driver is fine btw, i never got anything from those tweaked ones.
Quote:
I can run it at 1920x1080 at stock clocks
i have difficulties to imagine that. try the same benchmark as i did (look the "bioshock on your dell"-thread and post the results, if you like. i would really wonder if the grafik cards' performance is THAT different.

The severe artifacts are ONLY in the 3D renderer in ATI Tool itself (the cube). But yet it does not report any artifacts.

I have not attempted to play any games yet while overclocked.

But I am playing Bioshock at 1920x1080 with stock clocks, as previously stated.

Anyone have any recommendations?

lol 1920x1080 at STOCK CLOCKS with a very slight hesitation?!?!?!??!?!!?!? with everything on high? you must have a VERY high tolerance for low fps... i can only imagine 15-20fps at that kind of resolution on a 7900gs

Hey sport, I am just reporting the facts here. The FPS, I am sure, drop way low during intense action, but it keeps plugging away. It does not make the game a pain in the a$$ to play, just choppy here and there. I do not have FRAPs installed, nor do I wish to. Instead of juvenile picking or flaming, if you actually read what I posted and attempted an educated guess, I am sure all others would appreciate that as well. But as to my original post, it is all absolutely true. If you don't believe me, I live in a burb of ATL. PM me and I'll give you directions to my house.

does the atitool make any sounds? these sounds stand for artifacts found. it doesn't write "artifact found", but the clock at the bottom starts to count from zero.
and you should just lower the clocks stepwise until it gets free of atifacts. 450/650 might be fine.

i believe you, but the question is how? as talking about game fluidity is very subjective you should make a benchmark with fraps under similar circumstances like i did and then post the results. see this thread:
http://www.notebookforums.com/thread203270-9.html
you need to download and install fraps and then start the benchmarking with "f11" after leaving the diving bell and stop it when you get the gun from the woman with the baby buggy. remember to change the option in fraps, which limits maximum benchmarking to 60 seconds and set it to unlimited (turn time limit off). then you can copy the results from the logfile which typicall is found at C:\\Programms\\Fraps\\FRAPSLOG.TXT
your latest benchmar will be at the bottom lone.

no need for me to go 10.000 km. if you want to proove it have fraps installed, make a video and post it on youtube. or do the benchmark. if you don't want, there's no need to discuss anymore, and everyone will be happy.
and if you see artifacts, lower your clocks. but i don't understand: why did you oc and then don't play games with it?

My frustration was not aimed at you. I have trouble with people that immediately criticize instead of help. Read nvgear's post.... The reason I didn't leave it OCed - because of all of the visible artifacts in the ATI Tool 'cube'. I didn't hear anything with ATI Tool scanning for artifacts - but was afraid to leave the clocks higher with the artifacts. I initially thought it was lack of power - so I ordered a 130W AC adapter from Dell. I really appreciate your interest....I will PM you my e-mail address and send you screen shots of what I'm talking about, and any other related information after I install FRAPS.

nevermind, i also didn't mean to ask you for the fraps thing because i don't believe you, but because it's the only way i know to really find out some facts about performance.
and if you have some dots on the ati cube, just lower the settings and try again.
as what i said, it should be ok at 450/650, if not, just go down in 10MHz steps.
and as for the power supply: don't forget that it only gets dangerous for the card, when you start bigger volt input (because of heat). as long as you stay with 1v and
some clocks around 450/650 nothing should happen.

maybe you could post the things on the thread, for some reason i have problems (technical) to answer pm here. might be some browser settings, don't know...

This is what FRAPS reported:

2007-09-04 11:11:41 - Bioshock
Frames: 4177 - Time: 281112ms - Avg: 18.859 - Min: 7 - Max: 28

This is with all settings high and with my resolution actually at 1768x992.

you see, the difference is around 11 fps in the avg. you should lower your resolution to around 1280x720 (if you have an 16:9 lcd), turn ON global lighting, put everything on max and oc like 450/650, restart, and you should have a much smoother game experience... at least that's what i did to make the game playable in my opinion.

I'll try that the next timeI play the game.

I assume 30fps is the target...

yes, you should get something like that as we have similar hardware. you'll see, it feels MUCH better..
