Altering CPU voltage

post #1 of 5
Thread Starter 
Is there any software to alter my cpu voltage? I cannot access my voltage through my bios. Any help would be greatly appreciated!

I also read about the memory timings in the 101 Ram, however I am still in the dark. Do u just play around with your timings or is there some certain procedure to test as changes are being made? Should i just adust one timing at a time then test? HeLp!

If the CPU voltage can not be modified via the use of the system BIOS you will not be able to change the voltage using software on most occasions.
I do not know however of a piece of software that will allow you to change your CPU voltage, be warned however that changing anything via the use of software is a very risky procedure.

As for memory timings play around with them to a degree, don't go over the top as it can cause damage on rare occasions to the memory chips themselves. I would recommend the use of memtest to test the memory and make sure it is operating correctly

Thanks! I am first going to update my cooling and then try to push fsb as much as possible. I also have PC Wizard and when I check for overclock information, as I push my FSB, it also updates the memory speed. I have dr333, would this piece of information be important in the adjustment of my memory timings? I also noticed the increase of my fsb speed (which is stock 800mhz). It almost looked as though if I had adequate overclocking stability, I could push it to 3200ddr mem? Could u explain? Thank u!

When you increase the clock speeds of the processor you will also increase the clock speeds of the memory in conjunction to the CPU's FSB, unless a divider has been set. A divider allows you to change the ratio at which the FSB and memory speeds increase together and can be very useful.
If you intend to increase the bus speed (when in a 1:1 ratio) above ~680MHz you will need to either:
  • Increase the memory timings
  • Set a divider for the memory
  • Increase the memory voltage

The speed at which this needs to be done will vary depending on your motherboard and memory.
To make sure your system is totally stable run Prime95

Please Note: For safety reasons do not exceed 55C or 1.7v on your Northwood CPU.

Thanks again! I have that tweakpc for the adjustment of my memory timings, but I never noticed anything about divider ratio adjustment. My bios is very limited! Is there also ratio adjustment programs? My ratio is 5:4 and what is the difference between performance mode enabled or disabled? Timing is at 2.5/3/3/7. I am in process of possibly updating my bios with more flexability with my computer. Thank you so much for your patience!
