2 Question Thread

[i.Angel]

Yo guys. After reading the overclocking thread, I downloaded RivaTune and checked out my GPU settings. I have 2 questions that I need to ask, so bear with me .

First: I checked the GPU core temperatures and it said that my video card is running at a steaming 65C on idle! I have pretty good airflow, an 80mm right over the card and an 80mm exhaust... not the best but better than just an exhaust fan.

Second: After scanning through the stats, I noticed that the application said that my card is running x4 instead of x8! I have AGP by the way. Would I see a big difference in x4 lanes and x8 lanes?

Thanks for your posts guys!

56°C idle isn't that bad imo. GPUs usually run much hotter than your CPU. Now, if your motherboard only has an AGP 4x slot then your video card will only run that fast eventhough it may be an 8x video card. Ok, I'm not sure about this, but if you're video card was running at 8x instead of 4x it will be 2x better BUT I'm not sure.

Different AGP specifications provide varying amount of bandwidth:

* AGP 1X. 266MB/s (66MHz x 32bits ÷ 8bits/byte)
* AGP 2X. 533MB/s (66MHz x 32bits ÷ 8bits/byte x 2double-pump)
* AGP 4X. 1066MB/s (66MHz x 32bits ÷ 8bits/byte x 4quad-pump)
* AGP 8X. 2133MB/s (66MHz x 32bits ÷ 8bits/byte x 8oct-pump)

I'm not sure if 6600GT uses the whole 4X bandwidth.

another way to look at it:

if your motherboard supports a max of 4x agp, then there is a good chance the rest of your system is bottlenecking your graphics card.

That's just the thing, my motherboard and my video card are both x8 compatible.

Also, it's not 56C, it's 65C... sorry about that guys.

well why don't you enable 8x in bios?
