System Specs:
Enermax Noisetaker 470 watt PSU with active PFC
Asus P4P800E-Deluxe
Prescott 2.4a 1mb cache 133x4 (533) fsb with stock intel HSF
Generic Dell ram 512mb pc 2700 cl 2.5
BFG 6800 GT OC
Benchmarking is being done with prime95 blended torture test.
** Latest chipset drivers and BIOS as of 12/20/04 **
History:
Got the cpu and have it overclocked perfectly stable @ 3.11 ghz using ASUS AI. Read and realized that much more is possible with this cpu and have tried overclocking it further. I keep the AGP/PCI locked @ 66/33, the RAM ratio 1:1, and experimenting with voltage around 1.45-1.55v
Problem!
I keep the case open near me when testing new overclock. It appears that when I run prime95, there is a strange noise, almost like a tick, crackle, or a buzz. It is very thin, light, and high frequency. I have to silence my case fans and put my ear inside the chassis to hear it clearly, but I can still hear the noise if the case fans are silent and I am within three feet of the CPU.
This tick/crackle/buzz is coming from either the CPU or the motherboard area immediately next to the CPU (within 5 to 10 centimeters).
The tick/crackle/buzz only occurs for about the first 10-15 seconds while prime95 is running, and it does not appear to have a clear noise pattern, but I suppose it could be the sound of data. During this time, monitoring the temperature shows that the chip is not really running full blast yet, as temperatures are not climbing significantly, only one or two degrees celcius.
After the 10-15 seconds, the noise stops completely and prime95 appears to kick into gear, as the temperature immediately begins rising to the expected temperatures of about 47-53 celcius.
SO:
I don't know if it is that my voltage was too low (1.55v) or if something is malfunctioning. Could it be due to voltage droop? Is my PSU too little for this big graphics card and overclocked prescott? Could it be that this is normal? Would anyone with this same CPU be willing to try to listen for this as well?
Help!!
PLEASE NOTE:
I am certain that this is NOT sound card noise. I have put my head inside my case, and also unplugged the CPU fan; the noise still occurs, and emanates either directly from the CPU itself or within a few centimeters of it.
