Comment:

Could someone please explain the meaning/ use/ relationship in regards to all of these freaking setting I have on my motherboard that enable me to overclock. I have:
CPU Internal Frequency
CPU Frequency Multiple
CPU Front Side Bus Frequnecy
CPU VCore
RDRAM Turbo Mode
RDRAM Frequency:FSB Ratio

...And I can adjust any and all of them. There is just too many options and I do not know where to start for optimal o/c perfomance.

If someone could ponit me to a usefull tutorial or has a good explanation themselves, I would be in your debt.

HI
CPUV CORE it's the voltage going thru processor. CPU Frequency multiplier times CPU FRONT SIDE BUS EQUALS OPERATING SPEED of your processor. For expample, if your multiplier is 8 and FRONT SIDE BUS IS 100 then operating speed will be 800MHz.

be careful with overclocking. Some processors have locked multiplier. Carefuly increase FSB and voltage.

Thanks alex3182, that helps me to begin....

So, does increasing the CPU VCore add to the overclocking calculation? Or is it just FSB x CPU multiplier? Mt VCore is at 1.7 V now, and it looks like it is adjustable in 0.25 V increments? How far can I go safely, and without adding extra cooling mechanisms?

Thanks again....

Hi
When overclocking Core voltage should be slightly increased, don't go above 2.0 V. How far can you go safely depends upon your motherboard. Do you know your current CPU temperature? If it's below 50C then it's OK. If you increase FSB and computer restarts, hangs or behaves strangly then desrease your FSB. Also when overclocking you have to pay attention to CPU temperature. If it's above 55C and computer constantly hangs or reboots then you must reduce FSB. Careful. You might damage your processor. Don't increase it by too much.

Ok. I have installed Asus probe and this is what it is telling me:
CPU temp. is at 41 Celsius
Mother Board Temp is at 36 Celsius.
I have left the core voltage alone, and simply adjusted the FSB from 100 to 115 (the multiplier is locked). So I went from 1.4 Ghz to 1.609. Is that good? Not really any noticeable increase in performance though. If I try to increase it any more it just reboots and goes right back to the Bios settings telling me to re- adjust because something is wrong etc.
Ok, so if I understand you correctly, if I play with the Vcore now, just a little, I should be able to up the speed a little more?
I have also noticed that, I have to play with the RDRAM FSB in order to be able to increase the CPU FSB. I do not understand the correlation. Well, this should be interesting. What do you think?

Thanks again.

Hi Ant-man
Yes, it is good!
Very interesting.
Is it 41C at 1.4GHz or 1.6GHz?
You have normal temperature. When you increase operating speed your processor needs just a little bit more power. Increasing core voltage will not speed up your processor, but it should make it work more stable. Be careful with core voltage, too much of it can burn your processor. Do you have User manual for your processor and motherboard? If yes then read it, it should tell you what is the maximum core voltage your processor can take. If you don't have it then search for it on the internet.
Welcome to the world of overclocking!

It is 41C at 1.6GHz. When I increase VCore to 1.725 (from 1.70) the temperature goes up to 42C on average. It kinda fluxuates a little.

So what I tried next was increasing the FSB one more step, and WHAM. Blue screens all over the place. It boots normaly and everything, just bombs in windows. Maybe this is where I need to start playing with the VCore a bit more?? To stabalize? I got it up to 1.68 GHz. At that point I really did see some performance increases. Just really unstable.
I can't tell you how much I appreciate your help. Thanks again alex3182.

Hi ant-man
Back up important files/documents just in case.
41C for 1.6GHz is OK, so it's not overheating issue. If you play games temperature will rise upto 48C.
Yes, try increasing core voltage but DO NOT go above 2.0V. Can you give me a model of your processor? I'll do a research for you.
Some people run pentium4 1.8GHz at 1.6V.
If increasing core voltage doesn't help then decrease FSB.

Hi alex3182,

The processor is a P4 1.4Ghz 423 pin processor.

The motherboard is an Asus P4T.

I guess its kind of old hardware. I will try adjusting the VCore and see if I can get a more stable environment. There seems to be alot of possible configurations.
