Hello everyone got a quick question

When i run sandra(burn in ) my computer throttles up and down after the 20 run
(This only occors in sandra)
I have a 3.2e @ 4.0
Could it by any chance be the power supply???
I have a scottie which takes a 130 watts when oc'ed
a 9800aiw, audigy, 4 case fans, dvd, dvdrw, rator, hdtv wonder, floppy, 2 lights, 6 usb ports being used and 1 firewire port being used
And a 460watt silenx powwer supply
Why is it throttlingr???
Could it be the power supply??? will 550 watts stop the throtling
Thanks in advanced

No, it's most likely throttling due to heat.

Yeh I have never heard of somthing throttling due to lack of power. I think the system would just crash. What temps you getting?

35-38 idle 40-50 load (but usually closer to 40 50 only in long tests or games)
Thanks again

Your temp readings are wrong.

D0 Prescotts start throttling at 77C or 78C, I forget which.

If it's throttling, it's overheating.

Try touching the heatsink while it's throttling and tell us that it's only running at 50C. In fact, most Scotties IDLE at 50-55C, so I'm 99% sure your readings are way off.

Maxtor disgraces the six letters that make Matrox.

Well my temps can be like 5 or 6 degrees off because i have an asus p4c800-e But not more than that I have the Zalman reserator it keeps things nice and cool
But it doesnt throttle at any other time than on the burn in test in sandra Other than that I have no problems
So anyway Its not the power supply right?
Thanks again

SOrry I thought cpu throttlin was when the core speed increases and then decreases
Anyway thats what I really wanted to ask my cpu frequency flucyuates when under sisoftsandra by +/- 200mhz is that normal?
