help please, noob at overclocking encounters black out

clixy123 · Dec 29, 2007, 06:46 PM

Hi
I bought a computer second hand and have boot problems which are related to overclocking failure.

I have no idea about overclocking and would greatly appreciate someone's help.

These are the details:
-AMD computer
- Pentium4
-2.80 MHz, 256 memory

I don't know what else is relevant to tell you, but when my computer started (after hours of trying to boot and nothing but black screens), this was the message:

DDR frequency 333 Mhz
single channel or virtual single channel.
Checking nvram.
256 mb ok
auto detecting SEC master ATAPI cd rom
auto detecting 4th master ide harddisk
sec master dvd rom 16x 5.gv
4th master maxtor 6yo80m0 yar51ewo
Ultra dma mode-5
s.m.a.r.t. capable and status ok
<ins) pressed
overclocking failed!
run f1 for setup
run f2 for default settings.

I got these settings from the bios.

CPU external frequency is 141 mhz (is this the FSB, by any chance??)
DRAM is 266 mhz

PCI latency timer is 64

CPUvCore voltage is auto
DDR Reference voltage is auto

AGP PCI Frequency (mhz) is auto

AGP vDDQ voltage is 1.5v
Performance mode is auto.

Anyone guess what is the problem from these numbers??
Any help greatly, greatly appreciated...
Regards,
Clixy

Reset the BIOS to the default values if you get any option like that at startup. If all else fails remove the CMOS Battery on the board (it's not hard to find) and leave it out for maybe 10 minutes or so, then put it back in and restart the machine, this should default all your BIOS settings and you should be good to go.

Welcome to the forum.

Try raising the CPU voltage, just one or two steps to see if that helps. The CPU will run a little more hot but it's often necessary when overclocking.

"External frequency" is the FSB.

If you can't get it stable again, load default values for the BIOS.

first rule about low end, off the shelf computers

DONT OVERCLOCK THEM!

second rule

what you get IS what you get, dont try to speed it up in any way... results in tears..

now for overclocking, you cant go at it without knowing anything, and even more so you need a somewhat recent computer that has a BIOS capable of OCing properly and be stable at it....

to return your computer to normal, reset the CMOS, open up the tower and there should be either jumper pins or a battery, there should be labels on the motherboard that say CMOS jumper.....

set it to "clear CMOS" and boot the computer up, it should then clear out. then shut it back off and put the jumper back to its original state.

if you got one with a battery, easy way is to just pull the battery out and let it sit for 5 minutes.

dont ever use software to overclock your system, use ONLY the BIOS/CMOS settings.

just so you know, that processor is an Intel Pentium 4 not AMD.

i highly doubt his computer even allows changes in the BIOS so he shouldnt be overclocking that thing at all.

clixy123,
if you want to (or have to) clear CMOS values, then i suggest you refer to your motherboard user's manual for how to clear the CMOS.

here's below is a general informations about how to clear CMOS. however, each motherboard can be different.

=========================

Clearing the CMOS by using a Clear CMOS Jumper:
To clear the CMOS values, place a jumper cap on the two pins to temporarily short the two pins or use a metal object like a screwdriver to touch the two pins for a few seconds.

• Always turn off your computer and unplug the power cord from the power outlet before clearing the CMOS values.
• After clearing the CMOS values and before turning on your computer, be sure to remove the jumper cap from the jumper. Failure to do so may cause damage to the motherboard.
• After system restart, go to BIOS Setup to load factory defaults (e.g. select Load Optimized Defaults) or manually configure the BIOS settings (refer to your motherboard user's manual for BIOS configurations).

You may clear the CMOS values by removing the battery:
1. Turn off your computer and unplug the power cord.
2. Remove the battery from the battery holder and wait for one minute.
(Or use a metal object like a screwdriver to touch the positive and negative terminals of the battery holder, making them short for 5 seconds.)
3. Replace the battery.
4. Plug in the power cord and restart your computer.
