Please Post All New Or Uncovered BIOS Options Here!

LOL! Every bit helps, StevenV! Thanks!

Will note your request and work on it ASAP!

Didn't find this one in the BIOS guide.

OS/2 Onboard Memory > 64M
[Disabled] [Enabled]
I don't know what it means.
ASUS P4PE
Intel 845PE

Video Memory Cache Mode
[UC] [USWC]
UC is uncacheable - USWC is uncacheable, speculative writing combining
ASUS P4PE
Intel 845PE

Thanks.

Hello jjvb,

For reasons best known to themselves, many manufacturers choose to use different names for the same BIOS option. Fortunately, very little guesswork is needed to figure out which are similar ones.

The OS/2 Onboard Memory > 64M you mention is the same as the more common OS Select For DRAM > 64MB BIOS feature covered in the BIOS Optimization Guide.

The same goes for Video Memory Cache Mode. It's the same as USWC Write Posting, also covered in the BIOS Optimization Guide.

But I thank you for listing them here. It's good to find out the different names of similar BIOS options. I can then post them in the BIOS Optimization Guide for completion.

Thanks again and keep 'em coming!

Thanks for the reply Adrian. This is a great resource. I appreciate you putting it together. I didn't notice the USWC Write Posting in the guide. Guess I should have done a search.

Hey, that's perfectly alright, jjvb! That's why I really appreciate you posting the ASUS settings here. It will give me a chance to add them (BIOS options with similar names) to the guide.

Hi Adrian, thanks for the reply
I got this reply from Iwill's "Tech Forum":

That setting is dealing with the ISA to PCI bridge. The chipset generates the ISA bus clock (ATCLK) from an internal division of PCICLK. You can set the speed of the AT bus in terms of a fraction of the CPU clock speed, or probably best to leave it at the fixed speed of 7.16 MHz.

hope this helps

Here's a couple from my mem settings, located under 1.Soyo Combo feature - 2.Advanced Tune-Up Settings:

DRAM Burst Length
options = 4/8 (4 = default)
"increase DRAM performance"

DRAM Access Time
options = 3T/2T (3T = default)
"increase DRAM performance"

DRAM Queue Depth
options = 2/4/3 level (4 level = default)
"increase DRAM performance"

DRAM tWTR
options = 1T/3T (3T = default)
"increase DRAM performance"

Write Recovery time
options 2T/3T (3T = default)
"increase DRAM performance"

as you can see, Soyo is very descriptive on what these settings do
I tried asking the guys on Corsair's forums, but got nothing back. I apologize if any of these were already covered (I didn't see them in the BOG).

My Rig:
AMD 1800+
Soyo Dragon Ultra Plat. KT400
512 PC2700 DDR C2 Corsair XMS
ATI Radeon 9500 Pro
SB Audigy X-Gamer
WinXP Pro

Ack, was wondering what these options did. Mostly for information now, since I now longer own this board, but maybe they will provide that magical 50% system speed up we all dream of to some lucky person out there =)

Ironically, i wrote these options down to submit them to the bios guide like 4 months ago, and I just now found it while cleaning the desk! This obviously also means no rush unless you're feeling uncharacteristly bored some evening =)

Motherboard : Abit KR7a-RAID
Chipset : VIA KT266a

Under the memory timings section

BIOS Option : Rx6C overwrite
Options : ?
BIOS Option : Rx6D overwrite
Options : ?

Under Advanced Chipset Features? - i don't remember for sure, it's where all the other AGP driving value stuff is.

BIOS Option : AGP Read Synchronization
Options : Enabled, Disabled

I wish i still had this board to get more information on it, the memory options only appeared in the very last bios updates for the KR7a, so i'm guessing they might be some sort of compatibility workaround. AGP Read Sync is probably some generic name for something already covered in the bios guide.

Mostly historical, but maybe might help someone out!

Motherboard: DFI AD77 Infinity (KT400 based)
Bios: Award-Phoenix
BIOS Option: Clock By Slight Adjust
Options: A Number

[Adrian Wong]

Hello zwouth,

You did not list down the options available for the Rx6C overwrite and Rx6D overwrite BIOS settings. Can you list them down for me? Thanks!


Hello thomasj,

The Clock By Slight Adjust is just a BIOS option that allows you to select the FSB clock speed. Nice name but it's nothing more than the FSB Speed or CPU Ext. Clock Speed options found in other motherboards.
