Guide: Overclocking the X300 (Or really any mobility ATI Card) - Page 3

Redone! With pictures and all!
If there is anything else you want, feel free to ask about it!
Also, mods, I would love a sticky on this if you please!

Hmm...interesting. Well I might rewrite it again, as I'm starting to like ATT now that it works for me =P. Though, I did download the version from Guru rather than the Omega one. Mainly, I want to go over the advanced tweaks in it, such as enabling some settings for performance, and some for image quality (such as line aa)

Like I said, I redid it again for ATI Tray Tools (kinda.) Put in a whole new section just for tweaking the most performance out of the card.

But if you did that wouldn't it screw up the point of Powerplay? It would start up needing to much power and crash, and BIOS flashing can be very dangerous. Really I don't know of many people who would rather have to overclock via the BIOS rather than overclock via the desktop.

How would having a BIOS flashed overclock be more stable?
Say you put the BIOS overclock too much, and you didn't realize it until your about 3 hours into a game and it crashes cause of an over-overclock? You can't lower the clock without having to reflash it, and it won't reset itself down to stable clocks by VPU recovery if I'm correct.

Oh, well it sounded like you were.
I think I might change the settings again. I like playing with settings, for what reason thought I have yet to figure out.

It's minimal, but helps out. You should be able to get about a 30% increase in frame rates, and even though that sounds like a high number you have to realize how low the framrates can be to start off with. If you overclock the GPU from 297 default to about 400, that is a 30% overclock. The default score in 3DMark05 is about 1400. After the overclock, you should be getting 1800 or more 3DMarks. Also, the memory has about a 50% overclock potential (millage will very) and though it won't offer a 50% increase in FPS, it will help with running higher texture qualities as it will be able to "feed" these larger texture files to the core 50% faster than it used to.

Yeah, I've found that almost all games (or at least the demos) will run with at least medium settings.
Doom3, Quake4, and FEAR can run 800x600 with medium settings and be playable. FEAR I think looks much better though when you set the videos on maximum, as that really isn't a very taxing effect. Also, using DX8 shaders will help improvment by a lot, but the game looks really bad without DX9, and I can only imagin what it looks like with pixel/vertex shader 3.0.

Call of Duty 2 runs fine at 1280x800 with trillinear, no AF, and DX7. Zfeather smoke doesn't seem to bog it down that much either. Half-Life 2 is the same way, recomending high for all settings, and then switching to the same widescreen resolution. I will admit that a nice graphics card with AA and alpha-texture filtering enabled would really help out the fences, but you can get by if you don't pay attention to them.

I haven't tested Battlefeild 2 performance to throughly (as it is not really my cup of tea) but the game runs nice at medium settings with 800x600, and you could improve either settings or resolution.

Need for Speed: Most Wanted plays ok too up to 1280x800 on high detail, but not with much AA or AF. You may be able to get by on a lower resolution though.

That's all the demos that I had downloaded, and we just got our DSL cut because it was costing us to much, since now that I have my permit and need 100 hours behind the wheel, gas has taken a higher priority over internet (now we use the 6 months of Earthlink! Boo AOL!)

I just figured out what you are talking about, but I'm not sure if I understand what you are supporting: overclock on battery, overclock via BIOS, or not overclock via BIOS?
