Kinda OT: Ram overklokking

I am planning to overclock my system rams to some degree. I have pc133, so
don't care if they burn up or something.

What settings can I overclock which give good stability/performance ratio?
Mb is Kt7A by Abit (kinda old).

My Ram settings (reported by cpu-z)
DRAM Type: SDRAM
DRAM Size: 512 MBytes
DRAM Frequency 133.3 MHz
FSB:DRAMFSB + 33 MHz
DRAM Interleave 2-way
CAS# Latency 2.0 clocks
RAS# to CAS# 3 clocks
RAS# Precharge 3 clocks
Cycle Time (TRAS) 6 clocks

I think it's more a try going higher till it screws up then back off a notch
or two. Any table is only going to give you an "idea" of where to start
trying as I suspect there's to much tolerance built-in to all the components
to state catagorically "x" will work and "x + 1" won't.

On my Tyan Trinity 400 S1854 mb, I've run generic 133mz ram at 140mz (upped
fsb) reliably 24/7 for years now. One notch higher and system doesn't make
it far. A friend of mine with exact same mb (tech at place I purchased)
can't up his at all without problems? Therefore I'd suggest any specific
target is hit or miss.
 
1. You need to up your VDIM voltage to increase stability before you start
overclocking, so do this first if your MOBO supports it. On my machine
(DRAM) I have increased from 2.5 to 2.7 (the safe max is 2.8V...most MOBOS
dont let you set these high enough to cause burnout - except (Im told)
Shuttle boards)
2. Most mobo bios's have the option to change the memory settings between
standard and turbo, and the easiest way to max the memory after the increase
in the memory driving voltage is to select turbo. See if it comes up. iF
not, then you need to play around with the figures manually. BTW, looks
like your memory may already overclocked via the CAS latency - it is
usually 2.5. also your DRAM interleave is set to 2 way, and most computers
can handle 4 way (its faster).
2 After that, the only real thing to do is slowly increase the frequency.

Your memory is more likely to cause lockup well before it burns up btw ;)
Oh, make sure you know how to reset the CMOS before you start, you may get
stuck if your computer locks up and you dont know how to reset the
overclock!

Everything you need to know about that motherboard, including optimal memory
settings and overclocking tips, is here:

Did you know you could run an XP at 2ghz+ on it? Head over to
alt.comp.periphs.mainboard.abit and look for any post by Wes Newell. In his
sig is a link to a site that provides details.

There are still lots of happy KT7A owners around. I kept mine for three
years, and ran an Athlon 1 gig, a Tbird 1.4 and a Tbred 1700+ @ 2100+.

With Crucial/Micron PC133 I was able to run stable at 140 mhz with the
tightest timings. The ram would go higher, but because the AGP and PCI bus
is also overclocked on that chipset, my NIC would get wobbly.
 
Thanks A LOT!!! I'll definitely look into those pages and tips and let you
know how it went.
Oh and btw: C-mos note:
I was getting sick of opening chasis just to reset it. So i kinda modified
it. Made a cheap push switch by connecting long! wires to a 3-hole jumper :)
I just puch that little button (in a open pci slot) for 3-5 sec , after
turning of the power, of course! :)
