Fastest CPU for older KT266A board?

[Nessism]

I've got an Epox 8KHA+ board, the type that doesn't support Thoroughbred processors, and was wondering what's the fastest processor I could run on it? Is there any particular speed Palomino XP that is known for overclocking? I have good cooling and ram so that shouldn't be a problem.

Thanks.

As far as I know, the Palomino's were not really great overclockers in general. I had a 1500 that would do 1700 reliably, and a 1700 that would do 1900 (don't remember the actual GHz ratings).
Are you sure the board won't support Tbreds? The CPU compatibility list has the 8KHA+ rev1.3 shown as not supporting the Tbred, but the BIOS date for that is from December of 2001! The latest BIOS for the 8KHA+ is from May 2003.
The only thing with a board like that is that it probably doesn't support multipliers over 12.5x, at least not manually set ones. It should be able to read higher ones, but the option for over 12.5x just won't be in the BIOS.

The AROIA/AGOIA 1600+'s were known to hit 1.8+ ghz, which is a PR rating of about 2200+. I speak from experience, my old 1600+ got up to 1.9ghz. Do KT266a boards have the 1/5 divider? I think that would be your biggest hurdle if it doesn't.

(My overclocks are on a KT333 board)

I've not seen a Kt266A board with an official 1/5 divider although I think some Epox board had it. I'm using a Tbred B on my board now and it's at 2.2ghz.

None of the epox kt266a boards have a 1/5 divider. But the point is moot because the 8kha+ does supports the thoroughbred. Get at least a 2100+ if you want to OC. It doesn't OC the 1700-2000+ well because it doesn't work quite right with the 1st L3 bridge.

I have an SL-75DRV4 Soltek board with the KT266A chipset and I can't put anything larger than an XP2000 in it.. they have a new BIOS that allows support for the XP2100+ Palomino core (old 2100+) but that's where it stops. I tried my TBred 1700+ in it, and it woudn't work. 🙁

FYI I have a shuttle ak31a kt266a board running a tbred b 1700+ at 2250. I had to cut... some bridges, can't remember which ones, to enable the remapped multipliers (i think it's 7-->15, 8--> 16, and 9-->17 or something like that).

zephyrprime is right. The Epox 8KHA+ does support TBreds. Here's a CPU support list for Epox mobos:

Not really updated, but you'll see TBred is supported 🙂

Thanks to everyone for the info. Seems to me its Thoroughbred or bust. The part I don't understand is why the older version of the 8KHA+ (the version I have) doesn't officially support Thbred whereas the newer version does. Is this entirely due to the multiplier or is there something else?

with the newest bios update, you will be able to run any AMD XP prcoessor that runs at 266mhz FSB. (i think the highest is 2600+)

 

[touchmyichi]

Even though you support a 2600+, I wouldn't advise you getting that model since some of them are available in the 333 fsb model which wouldn't work, just to let u know.

 

[Tummy]

Wouldn't it work, just not at 333 fsb unless your particular board can oc that high? i mean, it'd just be like underclocking instead of overclocking 🙂

I too have the older KT266A board, is a MSI board which has multiplier of 15x. vcore range from 1.725-1.85. I was wondering would it be possible for me to upgrade to a XP 2400+ which has 266FSB and 15x. I have check the MSI website for processor support, and according to them the max processor is 2100+ the (non t-bred). Would the XP 2400+ processor work on my board if the vcore is suppost to be 1.65??
