Videocard FAQ: Drivers/Overclocking/Modding, Oh My! - Page 3

That's 400 MHz, I would think that you could notice that.

My 7800GTXGo stop to work. From yesterday night, when i have tried to USE ArticSilver 5 on CPU and on GPU, when i remounted the vid card didn't work. The PowerOn led (the first on the left) flash fastly every time i try to power on the notebook. With the old 6800Go all works correctly.
What's the matter?
help, please

anything could have happened, but the worst case scenarios are that you either had a static discharge and damaged the GPU or that you overtorqued the heat sink screws and damaged the board. exactly what did you do and what precautions did you take?

also, it seems you overclocked your card pretty high. did it ever heat up too much?

Try reseating your 7800gtx heatsink back on. Or you might have tightened the nuts too tight..?

Best of luck!

Please explain overclocking my 7900GS in dummy terms...

Hey everyone,

I have read so many threads about the 7900 GS in this forum that it is amazing. I had recently bought an E1705 with an X1400 and big surprise, I'm on my 3rd replacement system from Dell. Some of you recommended upgrading to a 7900GS so I did. I bought it from Dell for $270 and that is only a single pipe. I know, hella expensive, but oh well. They were supposed to give me $100 off which made it a much better deal since they wouldn't customize the replacement system with it, but as always they stuck it to me and said the conversation never existed. Never mind all that though, here's the question...

I am not a gamer at all, but most of you are very very knowledgeable about the 7900GS and overclocking. It is almost like you speak a second language that I can't quite seem to understand. I can get my way around a computer and have overclocked a CPU before, but when it comes to video cards I am a dumb A#$. I followed everyone's suggestions on installing the card, installing the new NVIDIA driver, and installing ATItool.

Now what I need to know is

• how do I use ATI Tool to overclock (what do the numbers mean like 2D and 3D, or searching for Artifacts etc...what the hell is an artifact)?
• what are some good safe numbers to overclock my 7900GS in order to achieve maximum performance with Vista, without being a gamer?
• do i still need to unlock the bios?
• any other performance suggestions?

So far you guys were all right about the 7900GS and I'm glad I took your advice. My E1705 performance has increased, but it is not fast enough yet. I really appreciate all the help. Thanks again,

I'm only getting a 4.7 W.E.I

Thanks for the info. What can I do to increase performance outside of the video card? For some reason I am only getting a 4.7 W.E.I. It seems that even with the 7900GS I am still using 48% of my system memory just running Vista which is close to what it ran at with the X1400 which was only 128 dedicated video memory. My CPU is pretty jumpy also. Back and forth between 2% and 90-100% I just pulled this dell system out of the box yesterday and immediately installed the 7900GS. I have installed very little of my software also. Any Ideas?

Uh...maybe someone else will come along and give you the gist...if not I'll be back tomorrow. Anyway, if you aren't interested in gaming, there's no point in oc'ing the card

Edit: Again, I really have to stop leaving these tabs open for hours

Thanks for the advice. I guess I am SOL on increasing performance. I thought the system had a good configuration, but I guess Vista just bogs it down. I still don't know why my memory is running at 50% after installing the 7900GS. I figured it would utilize way less memory then the X1400 which was sharing it with my system. Oh well. Thanks again

With the 7900GS is it possible to not have it share the system memory? I was getting familiar with the NVIDIA Control Panel and noticed that my system is still sharing 495mb for video. I changed all my setting over for performance versus quality but I guess that would explain why my memory runs at 50% with only vista running. Any help would be greatly appreciated. Thanks,

Performance just reduces image quality allowing you to get more frames per second which is really just more performance as the setting implies. Anyway, I dont have vista so sorry I cannot help you. It doesnt make sense to me either why the system would share memory with the card but whatever. However, if after figuring all this out you still feel the need for more performance then you can try to oc your card. Just to see if that does increase performance at all. Just beware that this will increase stress and temperatures on the card. If it doesnt help you can always put it back to stock provided you either backup your stock bios or find one here.

For the 7950 GTX 512 MB Vid card for a 9400/E1705 is the photo guide available or is it identical to the 7900 GTX? Thanks.

i believe it is the exact same thing. Once you actually get the e1705 opened up it should look fairly simple. I just did it with a 7900 GS single pipe, but I had used the photo guide for the 7950 as a reference and I could see what they were talking about step by step.

the 7950gtx has the same form factor as the 7900gtx

looking forward to OC my FX-2500 GPU

Hello guys, I overclocked my 7900gs using the 1.24v bios and it's running at 630/740 stable at the moment on a 130w psu. My question is i've seen lots of ppl running the memory core at 800, but i can't seem to past 740, why is that? everytime i try 750, the computer screen would turn completely red with horizontal lines (meaning the video card crashed, then i have to reboot)... is this really my 7900gs oc limit?


thanks.

I overclocked my 6800 Go 256 Mb card and right now it is holding off on 369/748 MHz - ? Is that enough or it could be pushed further? . I have Forceware drivers from LaptopVideo2Go - 87.25 -the most reliable for 6800 anyways they say.

Okay, i followed GeForceTony's instructions on deleting the old drivers and installing the new drivers (i'm using 156.65_m6). Upon reboot, ati tool (ver .27b) does not work. What gives? How am I supposed to be able to set the clocks now?? edit: i figured it out. I needed to right-click on it and "run it as administrator".

Yes, don`t push it past the point of abnormal screen! You risk the chance of damaging the chips and it could stay that way, even at underclocked speeds. It`s happened to me before. I hate it when I wreck hardware.
