VCore voltage or VIO voltage ?

[Matthew A.]

I am currently experiencing one or two lock-ups a day and maybe one blue screen of death a day depending on what progs. I've got running at the same time. The blue screens don't concern me really. The freeze ups or lock ups whatever you want to call'em, do. I bumped up my FSB from 146 to 150 Vc @1.65 +or- 5% and VIO @3.45. Which one would should I adjust. I'm not sure if the lock ups are AGP related or CPU related. My BIOS does not give me the option to change the AGP divider which is probably set at 1/2 since I'm using a 133FSB CPU. I also have the option of adjusting the voltages of the Memory Translator Hub and Memory Controller Hub. Yah yah ya, I know, the 820 chipset %#ck up from Intel. I just had to throw the MTH/MCH in there just in case some one in this forum knows when adjustment of them may be helpful. Anyhow, my computer can only utilize PC100 ram so my two sticks of Kingmax PC150 222 is only running @ 112mhz memory speed, so I doubt that it's a ram freq. issue. My temps are cool w/cpu @80 idle and maybe 100 when really busy. Mobo @ 84 (temps in F`) Anyone ?

You need way more voltage. You couldn't power a straw made windmill on 1.65v - get her upto 1.85v and just enjoy the good times

. Why would I want to raise the Vcore voltage to the highest my chip will safely tolerate when it had been very stable at a Vc of 1.65 and the FSB @ 146. I don't mean to sound ungrateful because I very much appreciate your time and help. It's just that I don't think I understand the reasoning behind your logic.

I agree with Wild Andy. You either have to be happy where you are with the board or bump the voltage if you want to run faster. I guess the other option would be to try to get a better heat sink and fan for the CPU.

You can't expect to just go up and up in FSB forever. It is very common to go up to 1.85 volts. I had to go to 1.9 volts for a stable PIII 700 (100) at 933 (133).

What is your CPU and motherboard? Is it a 133 FSB CPU?

Thanks!

How can you call lock-ups and bsod's stable?

OK, I understand that I have to adjust for increases in power consumption with increases in voltages accordingly. So the voltage increase that wild_andy_c recommends is what he calculates to be the voltage needed in able to provide for the increased consumption of watts that the additional increase in mhz. will use. Correct ?
The mobo is an Asus P3C2000 w/PIII 600EB cA2 @ FSB 146
I guess I was under the false impression that CPU's with 133 FSB consumed less power then that of 100 FSB CPU's of similar speed because of lower multiplier used. Also, can you please tell me what the highest temperature for the CPU is before it is considered unsafe. Asus's Probe doesn't give an alarm until the cpu reaches 167 degrees F`. which seems awfully high. Currently I see temps while under load as high as 103F` with ambient air @ 78-82F`. Thank you for the help
