Plz Help! OCing a T1200/266 on KT7A

[The Doors]

Hi,
my system is rock stable @1390 1.725v (10x139) with Fop32 (idle@31C & full load@48), but I want more power :-)

so I've tried to set multiplier to 10.5 or 11 and Fsb@133 with VCore between 1.725 (@48C) to 1.825 (@50C) but freeze into Win98.
It sounds strange that 139x10 works fine and 133x10.5 don't.

I can't reach higher Fsb coz mem mod are cheaper and works fine max@139 so what can you suggest me?

Note: case have different Sunon's fans installed (1x120mm & 2x80mm) and Enermax 350Watt.

you did a nice job but I don't know how much higher you are going to get that guy. Are you sure the L1's are closed. I know that most are closed but a lot of them seem to slip thru open for some reason. just lower the multiplier to double check it! oh never mind you are 9x133 default running at 10x133. well I wouldn't be too angry with the OC you did.

Here's the deal, I had the same problem until I switched the K7 CLK_CTR in BIOS from default to optimal. Try this and you should reach that multiplier and higher.

Tacoman's fix worked perfectly for me when I had the same exact problem with my KT7A.

Also make sure you dont have the "WW" version o the KT7A bios because is doesnt have the K7 CLK_CTR option, as I found out teh hard way. If you do have the "WW" version get the ZT version I have found it to be the best so far.

Thanks a lot guys, especially for Tacoman's fix, you say right! :-)
now my system is rock stable @1420 1.75v (135x10.5).

Have a nice OverClock!
