Problem after overclocking - Page 3

post #21 of 23
Download a tool called cpu-z. Note the stock cpu fsb, ht, and nb speeds. Overclock 1mhz at a time on stock voltage till you get to a wall. Add voltage as needed one click up for cpu, and manually set cpu/nb voltage. Once no cpu voltage helps try up'ing the cpu/nb voltage. If you got that far note in the cpu-z tool the ht and nb frequency's. They should have went up with the overclock. Check your stock default frequency online. If you look on AMD's website under processors it will say the stock clocks. Check the mobo's vendor site for max ht frequency, older boards don't go much over stock, you might need to drop it. If your board has the option you can raise the ht or nb voltage for the board, but it can cause issues with the board, or damage as well. If you listed or updated your signature with your components it would help as well a the stock ram speed. No one knows what you are working with so its hard to say what else to try.

Hello first thank you for the respond i have serch this cpu/nb voltage or samting like this in my BIOS but i didn't find it olso i downloaded the program Dual Core Center and serch there and find it but i can't change it it say N/A on the temperature is the same again N/A wath is that mean?And wath you mean with ''WALL"

Each chip will have a frequency wall for the stock voltage, and will need more voltage for the higher clock, go up slowly when overclocking, Example my chip needs only 1.53v for 5ghz on the core but past that it needs 1.59v for 5.1ghz and is not fully stable, each chip is different, this is how it has always been, its about luck on getting the best combo of parts such as cpu/ram/motherboard/psu for overclocking one sub standard part and it the whole overclock could be very low or minimal vs using better componets, Cpu is the hardest to get a good clocker compared to the other parts.

Helpful tools:

HWinfo32&64: http://www.hwinfo.com/download.php

CPU-Z: http://www.cpuid.com/softwares/cpu-z.html

Stress test tools:

OCCT: http://www.ocbase.com/index.php/download

Prime95: http://www.softpedia.com/progDownload/Prime95-Download-76537.html

Memory stress test tool:

Memtest86: http://www.memtest86.com/download.htm

These are the basic tools to use for overclocking.

You will have to do more testing you might have a weak or degraded componet.
