Video setting in BIOS question

[moosey]

I have an A7M266 by asus and an ATI Radeon 7500 video card (64MB). In my BIOS, how should these 2 values be set?

-Graphics Aperture Size....128 or 64??
-Video Mem Cache Mode...USWC or UC??
-AGP Fast Writes...enabled or disabled??

Thanks

64mb is fine ,but if you have 512mb of main system ram or more then 128mb won`t do no harm.


AGP fastwrites,now this depends on your PC and its stability,try it on and if you get stability problems then leave it off,btw there`s virtually no difference with fastwrites on(enabled) and off(disabled) speed wise.

As to USWC,

This BIOS feature allows you to control the USWC (Uncached Speculative Write Combining) write combine buffers.

If enabled, the write combine buffers will accumulate and combine partial or smaller graphics writes from the processor and write them to the graphics card as burst writes.

If disabled, the write combine buffers will be disabled. All graphics writes from the processor will be written to the graphics card directly.

It is highly recommended that you enable this feature for improved graphics and processor performance.

However, if you are using an older graphics card, it may not be compatible with this feature. Enabling this feature with such graphics cards will cause a host of problems like graphics artifacts, system crashes and even the inability to boot up properly.

If you face such problems, you should disable this BIOS feature immediately.

Hope this helps.
