k7s5a overclock BIOS

My question for all you lovely people out there is, I heard of a BIOS for the k7s5a overclock bios, so first of all where can I find it? Second, does it support voltage adjustments?
 
no voltage adjustments...only fsb options allowed by the PLL, which are as follows:

112 mem/fsb
124 mem/fsb
145 mem/fsb (maybe it's 140, i can't remember)

and one other non-standard (i.e. not 100 or 133) one in the 150mhz region...

check it out at ocworkbench

navigate to the forums, and then the ECS category...at the top there's a faq i suggest reading as well as the OC bioses and drivers
 
Look at www.ocworkbench.com....

Also no it does not have voltage adjustments....That is the most limiting factor in my mind with the ecs mobo. You can pencil in the bridges on tbirds to give you 1.85v, but my experience without multiplier adjustments it is all fsb boosts and most pc2100 ddr can't cut it unless there is a slight adjustment on the voltage to the ram....

So unless you are going to run some pc2400 ram (and this may be a long shot) I doubt you will get any stability over a fsb of 142.7


Save yourself the possible flash catastrophe and get a software fsb ocer like cpucool (it has support for the pll clock on the ecs board) and boost it there...I have found 142.7 to very stable...non memtest errors, but 146.6 is unobtainable for total stability...It will post..

Now the oc bios I believe is going to give you like 4 or 5 options up to150mhz anyways...
 
You can find it @ ocworkbench.com

Look in the ECS forums section, it is listed on the page. No BIOS for the K7S5A supports voltage adjustments, you have to change your pencil marks to adjust 🙁.
I use this BIOS on one of my K7S5A machines and it runs a 650 duron oced to 900mhz (6.5x138). I dont really think its worth getting it unless you are going to mod your board for multiplier adjustments because it doesnt have any FSB options between 138 and 150.

You can also get a golden socket for about 50 dollars somewhere but why not spend the money on something else on your computer?
 
i jsuit came across this, but there is a small dos utility written that allows you to write FSB/MEM settings ot the CMOS that are "hidden" - i.e. the 112/112, 124/124, etc., settings that don't show up in the official bioses..

a reason to stick w/ the official and latest bios version over the o/c bios is that the latest bios has certain compatibility/stability issues fixed, whereas the o/c bios doesn't because it's based on an older bios version.

i've noticed the increased stability (mostly pertaining to memory timings i believe) in the latest official bios.

when you write ot the CMOS, the worst you can do is screw up the CMOS settings, which can of course simply be cleared by a jumper...no biggie...also, bios flashing is NOT a problem, especially since the AMI bios uses boot block..so if you fail the bios flash, just pop in a disk w/ a working BIOS (i.e. the one you back up before flashing) labeled AMIBOOT.ROM and it should recover it (i did it once, and it worked).

search the ECS forum on ocworkbench - if you can't find the thread i have the prog that i could email to you - or i could sipmly try to find it later and provide a link to the thread...

when u write to the CMOS, it'll show "reserved" under CPU speed in the CPU PnP settings menu...if u select the official settings and save, you'll have to rewrite to the CMOS using the dos utility to get the other unofficial settings back...works great - better than CPUFSB since you dont' need crappy 3rd party software that resides in memory and takes storage (albeit little) space.
 
The o/c BIOS only allows a 133/138 and the next step would be 150, so a 266MHz Athlon wouldn't benefit much from it unless you have a good one. My Tbird 1400 only made it up to 1450. A 150MHz FSB would cause the system to hang before it reaches Windows
 
Goi,

Most 1.4tbirds can handle that, but they need the l7 voltage bridge penciled in to set it to 1.85volts...

Most likely it was the ram and the lack of any voltage adjustments by the ecs to get to post...

 
Well, I gave up trying. I'm probably not gonna mess with the CPU anymore, especially since I'm using the Alpha 8045 which takes quite a while to install...I don't need all that speed anyway, that particular system is only used for DVD watching, RC5, internet browsing and very light quaking
