Solved Cannot overclock cpu :(

Specs: windows XP sp3, P4/1gb ddr2 RAM

i m havin a major problem......

I AM UNABLE 2 OVERCLOCK MY GRAPHICS CARD N CPU ANYMORE LIKE I USED TO.....WHENEVER I TRY 2 OC MY CPU FROM BIOS N SAVE THE SETTINGS........MA PC DOES NOT GET SWITCHED ON ON THE FIRST ATTEMPT IT RESTARTS SEVERAL TIMES BEFORE GETTING ON......AND MY CPU DOSENT GET OVERCLOCKED.............THIS NEVER HAPPENED BEFORE PLZ HELP........N D SAME IS HAPPNIN FOR MA GRAPHICS CARS I USE EVGA PRECISION BUT I CANT SAVE THE SETTINGS...........IT GETS CHANGED TO ITS DEFAULT VALUES................WHY IS THIS HAPPNIN...................PLZZZZZZ REPLY.............

I USE A p4 CPU (2.66 GHz DEFAULT)
nvidia 9500GT........
GIGABYTE G31M-ES2C........mobo

Also while you are at it, check your CMOS 'coin' battery. I suspect that if the battery is dead then you are getting an unexpected CMOS reset as soon as the power supply powers down. That is why you are resetting to defaults repeatedly. Replace the battery or at least test it.

Please turn off the Caps Lock!

You didn't provided enough info. Which CPU do you have? Prescott? What speed DDR2 do you have? Which FSB:DRAM frequency ratio are you using?

The 9500GT is a low end card with only 32 stream processors. Overclocking may improve it's performance somewhat, but it can't make up for it's shortcomings. What are the default GPU & memory speeds? What are you increasing them to?

its a Pentium 4(default 2.66 GHz) is used to o/c it to about 3.2.......but now even if i lower the clock (i.e make it 2.0 from 2.66) or even increase it.......ma pc refuses to accept those changes......after i save my settings i press f10......n ma pc restarts several times(4-5 times)[ACTUALLY ONLY THE CPU RESTARTS THE MONITOR REMAINS SWITCHED OFF].....till at d 5th attempt it switches on.........but dusent show d message "UPDATE SUCCESSFUL".coz of this im having 2 run my old P4 at default settings.........the same thing is happening with my GPU too i use EVGA Precision........i save my new settings but it gets changed to its default values after a reboot.
NVIDIA 9500GT
default values:
GPU Clock:550MHz i change it to:700+
Memory:400 i keep it as it is
Shader:1350MHz i change it to 1750+

Pentium 4 is not a good CPU and it will continue to be bad even if overclocked.
Can u see a difference between 2.66ghz and 3ghz(in games)?

9500gt isn't a gaming card but overclocking it will boost game performance.
When set the clocks with evga precision u have to click apply at windows startup(red circle) then click apply button.

"its a Pentium 4(default 2.66 GHz) is used to o/c it to about 3.2"

There are several P4s that run at 2.66GHz (505, 505j, 506), that's why I asked. To get it to 3.2GHz, you would need to increase the CPU frequency to about 160MHz? Are you increasing the CPU voltage? Did you lock the PCIe at 100MHz? Did you disable SpeedStep & adjust the memory multiplier? You still haven't said what speed RAM you have but that speed needs to be adjusted to hit the optimal FSB:DRAM ratio.

"Memory:400 i keep it as it is"

Why increase the GPU & shader but not touch the memory?

@fingers i think that may just be the reason.......which battery r u talking about is it the small round one just above the PCI express slot........and plz mention how do i test the battery.....n d problem regarding my 9500gt has been solved i am being able to overclock it now using EVGA Precision........

guys the problem still remains i tried changing d battery.......could dis be coz of poor power supply so i need to change my psu??
ma monitor has gone yellowish i think this may be coz of poor power supply
???????????????????shud i try changing ma psu then??will that help in o/c? or can this be due to my mobo?

"could dis be coz of poor power supply so i need to change my psu??"

Not likely. And since you haven't answered any of my questions regarding the RAM, memory settings, or BIOS settings, I'm gonna bail. Good luck figuring it all out.

Testing the battery requires a digital volt meter but if it is 5 years or more old, just replace it.
Read voltage in BIOS of all outputs (3.3V,5V,12V) they need to be within 10%.
Replace power supply if not.
Is your power supply sufficient for your system with graphics card or marginal?
About screen yellowing, try the monitor on another computer, try using onboard video instead of graphics card to test monitor and card for problems. Update graphics driver.

@ mickliq

sorry abt that.....
could u just list ur questions....and tell me how do i answer those?

could this be coz of my psu?
how am i supposed 2 know whether its working fine i use a gigabyte G31M-ES2C, is there any easy way 2 know whether all the components are working properly??eg my mobo, psu, graphics card ,ram, cpu, etc etc....the essential components.......an easy way.....!!!!!!!!!!!

@Fingers what do u mean by "within 10%" ??

One more thing i figured out if i tap the sides of the monitor the yellow tinge goes away........so this isent happning coz of my card is it....

and how do i update my bios????

Tolerance ('within') 10% or +- 10% means 12Volt can range from 12+1.2=13.2V Max & 12-1.2=10.8V Min. I would prefer to stay away from those extremes by a reasonable margin of safety, especially the lower range since you will get additional voltage drop under load.

Do not update your BIOS. You do not have the correct reason for trying this, it will not solve your problems, AND the risk of failing (creating a useless piece of junk) are too high. You only update a BIOS to solve a problem that is documented by the mfg that this will actually solve. A proper reason might be that a new CPU you purchased is not supported by the BIOS but the newer BIOS version DOES support this and you KNOW this because the BIOS update pages LIST the reason for their creating the update.

You need to TEST your CMOS battery BEFORE anything else! This is the ONLY thing that makes any sense as far as the problem you are having. You can get the battery tested at a local Radio Shack or similar store and if it is bad as I suspect then purchase a new one and have them test it before you leave.

Read your manual, BIOS set up section.

Post your:
Memory brand, size of each stick (in GB or MB), how many sticks, the speed of each memory stick (like: 533MHz DDR, etc.); The settings that you BIOS reports your memory is running at; Your memory multiplier or CPU/RAM ratio (which ever is there) ; The Frequency you are running your CPU at and the multiplier; Your PCI and PCIe(if there is one) or AGP frequencies; Speed step settings; Vcore Voltage reported in your BIOS; ANY thing else you adjust in your BIOS.

Upon reflection, this system is really old and outdated. Replace it, it is not worth the effort you will have to go through.

"i have a new one but the cpu (q8600)got fried due to extreme o/c"

You can NOT overclock a modern CPU to death, but you can overvolt one to death. Did you increase the voltage way beyond the recommended limit? If not, it's probably OK. What makes you think it's fried?
