Nice one Straffo. (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)
Will check out if I have a probelm with my new KT7A-RAID set-up.

Your system will be more stable if you allow the RAM's internal ID chip to set timings latency etc. Unless you have REALLY good memory (Crucial, Mushkin, Kingmax) manually setting these settings will likely result in lockups.
Memory interleaving can really improve performance. Most cheap memory sticks will lock with 4 way, but may be ok with 2 way.
Agp speed should be set to 2x in most cases for stability on VIA chipsets. 4x will likely result in occasional lockups. You may be able to run stable at 4x if you set the AGP driving value up some. WARNING: If you screw the driving value up you won't be able to see the screen to fix it. You will need a PCI video card to get back into the bios, or clear your cmos settings.

Cool, saved as a text file for reference. (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)
Thanks Straffo

Bloom: At least Abit motherboard bios's can be reset upon boot by holding down the insert key after a cold boot. Very handy if you manage to render your computer unbootable due to overclocking or other bios tweaking (http://bbs.hitechcreations.com/smf/Smileys/default/wink.gif)
Other option is to short circuit the 'clear CMOS' jumper which can be found on the mobo. Instructions for these can usually be found in the manual..

I believe the ASUS key for the same thing is home or end.

Why do you disable caching system and video BIOS? That is a big performance gain when you do.
System BIOS Shadowing (Enabled / Disabled) : disabled
System BIOS Cacheable (Enabled / Disabled) : disabled
Video BIOS Shadowing : disabled
Video BIOS Cacheable (Enabled / Disabled) : Disabled
------------------

I don't know how much of a performance gain you would get from that. One would think it would be a small one.
Generally you disable these things for stability reasons. If they are enabled and you are having weirdness, try disabling them.
Hmmm, I should test those on and off in AH and see if there is any difference.

Disabling Cacheing of System and Video Bios etc is indeed a good idea with modern systems, it does have no negative impact that i have seen and it certainly gains 3Dmark 2001 points when disabling.
It used to speed things up on my much older systems by enabling it, but now the opposite is true.
Nvidia also recommend you disable them as well, especially the Video bios as it can be handled faster by the Vid card itself.
This is an excerpt from this site, http://www.rojakpot.com/Speed_Demonz/BIOS_Guide/BIOS_Guide_Index.htm (http://www.rojakpot.com/Speed_Demonz/BIOS_Guide/BIOS_Guide_Index.htm)
However, modern operating systems bypass the BIOS completely and access the graphics card's hardware directly. So, no BIOS calls are made and no benefit from BIOS shadowing is realized. In light of this, there's no use in wasting RAM just to shadow the Video BIOS when it's not used at all.

Well, looks like I need to run a quick test! OK, so it used to be shadowing BIOS was a good thing (http://bbs.hitechcreations.com/smf/Smileys/default/wink.gif)
Thanks for the heads-up!

It's due to the hypothese that we are now using mainly windows not DOS as primary OS in fact under DOS there is a performance difference if shadowing is enabled but under windows there is no gain (the driver do direct access to the hardware by passing the bios).
<edit> should have read the last msg from cavalier (http://bbs.hitechcreations.com/smf/Smileys/default/biggrin.gif)

That's OK Straffo - I needed to post a followup anyway.
That was a great link to information and the most telling part is where the guy accidentally wiped out his video BIOS but Windows continued to run like a champ.
I've never had any stability issues with my BIOS shadowed and cached, but apparently I've been wasting the high-speed cache to do it.
I didn't do any hard core numbers testing yet, but I don't notice any difference at all between shadowed and not - which is the minimum I would expect based on the above information.
Cool stuff.

Whats the benefit of interleaving the ram if the graphics card ram is being used?
-
The whole system will run faster.
The video card is only doing the video rendering. The CPU and Ram must do the all the math, positional stuff.. etc. etc. Turning on 4-way interleaving will speed your entire system up slightly, and should give you a small performance gain in AH unless you are currently very video card limited.

Ahhh, danke, have 64 meg aboard the video card so I think I'm safe for at least another week <G> aint computers wonderful!
