overclockin amd sempron 2400+ on an MSI motherboard

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View

all i know is dat my system configuration is :

MSI Motherboard MS-7061 (phoenix BIOS)
AMD Sempron 2400+ (1.67 GHz)
Geforce4 MX 4000 128 DDR RAM

dat's all i could get to know by myself. i wanted to overclock my cpu
in order to make it work a bit faster and also give dat extra edge in
gaming. could anyone tell me dat best possible way to overclock it ?

what speed is your ram?

errr... i dunno how ta find dat out Veritech but i guess its 256 MB
DDR @ 266 MHz


Re: overclockin amd sempron 2400+ on an MSI motherboard

where theres your first problem.

AMD chips run best when there fsb speeds are in sync with the ram speeds. as
it now, your cpu is out of sync (cpu @ 333, ram @ 266).

You got two choices in my eyes.

1. buy new ram, go for DDR400 if your board can support it.
2. Overclock your current ram

Unless u got real good ram, option one is really the best one.

to test the max speed of the ram. go into the bios and drop the fsb speed to
266ddr or 133mhz, if my memory serves me right your cpu has a mulitplier of
9.5 giving you a cpu speed of 1.2Ghz(a 300 mhz drop, don't worry!). Then
change the ram speed ratio to 1:1 instead of what it might be now(something
like 5:4). once this is done your ram and cpu should both be running on a
133mhz(266) fsb.

Once you've done that up the fsb speed by about 5 mhz, rebooting into
windows after every increase. Keep going till the pc crashes. If the board
fails to post, just reset your cmos, make sure you know all the settings

Once you have the max  fsb speed, drop it by about 10 mhz and that should
give you a good place to start testing for stability.

If you got crap ram, you most likely won't get past about 140 mhz, on the
other hand if you got good ram, you could get all the way to and past

However if you get new ram, you can go as far as the board will allow you.
200mhz is the golden mark for skt A. My setup runs at 184mhz fsb, giving me
a cpu overclock of around 200mhz allowing my 2600 @ 1.8ghz to run like a

i hope that answered all of your questions

Well, you got some answers but noone got to this: probably the factor
most limiting to the gaming performance in your setup described is your
video card. Don't know much about nVidia, but IIRC the GF4 MX serie is a
direct descendant of the good old GF2 serie with only DX7 compatibility.
Basically, you could go and get any modern video card and the games
boost would be visible.

If you end up with an ATi card, stay away from the SE models unless you
definately know what you are doing. Their performance is strangled by
their narrower memory bandwidth, except for some certain models.

If the Sempron speed label means it compares to Celeron 2400 then I
guess a well balanced card could be an ATi 9600XT. Not the latest
technology and definately not the best speed but abything much better
would probably be an overkill. The price is not too high, either. If you
are going to upgrade the CPU and/or memory (you could use some more
memory, by the way, 256 is hardly enough to run even WinXP alone, maybe
if you run an older OS it is enough but not for serious gaming anyway)
the situation will of course be different.

If you are really tight on budget, go and get a second-hand ATi 8500,
the LE model will also do. Replaced with even that old a card you will
notice something has happened. Someone might also offer you a "real" GF4
card (Ti4200/4400/4whatever), it will give you something, too.

In short: get rid of that GF4MX and find something better. Ask your
local nerd kid to go shopping with you if you feel your competence is
limited, it is not a shameful thing to do.
