My Core 2 E6300 suddenly................

[EdzAviator]

At first setup, my Core 2 paired with 965P-S3 & Corsair VS ram is quick......
Now its running very slow, theres a change in its responsiveness...
I tried to format & fresh install my OS....

Its still the same.....

Is it my memory thats causing the delay responsiveness????? or IO??????

i also just built a core 2 system lately and i notice quite a bit of slowness when i overclock the system when the memory speed is slower than the cpu FSB...

What's the temperature?

 

[cmdrdredd]

are you sure that Deferred Procedure Calls aren't sucking your CPU time? Sometimes that happens to me and it needs a restart.

Usually happens after some app crashes for whatever reason.

C2D Thrive at High FSB and Memory Bandwidth.... you basically answered your own question....


The RAM is best if Run Async, and at the Highest Speed the Memory Can Run Without Heat Issues Or Stability problems. You may have to bump the Memory Voltage in the BIOS to get what you need.

i have just begun overclocking my E6400 and its at 2.8GHz right now....im running orthos for just a quick stability test and after 15 mins or so the CPU starts to make a very annoying high pitched squeek.....is it the HSF? or what? my temps have been quite high, mid 60's at full load...

RAM should be run synchronous with FSB with C2D systems:

THE fastest is running SYNCHRONOUS with FSB, but the total theoretical bandwidth should be GREATER than the FSB bandwidth.

Only thing is DDR2-1066.
http://www.hardware.fr/articles/623-10/intel-core-2-duo-dossier.html

Notice the larger gap between DDR2-1066 and the 2nd fastest RAM settings and the gap for other ones.

But, P965 behaves differently from 975X: http://www.digit-life.com/articles2/mainboard/i965-chipset.html

Clearly P965 is optimized for DDR2-800, and higher RAM speeds than latency(comparatively).

Please... you know enough to overclock a CPU but you keep calling your computer case a CPU. It helps if you make it clear what you're talking about. The CPU is not going to emit a squeal but the fans or hard drive might.

If you have a better heatsink/fan then try that, or go get one. Or better yet, open your case while it's squeaking and see if you can isolate the sound.

good article.

i have a core 2 duo e6400 cpu
i have 2gb crucial 533mhz ram DDR2 PC2-4200 (2 x 1 GB)

what tests do you reccomend i run to see if its at its top performance?

thanks

Actually running 400Mhz FSB 8x CPU Multi for 3.2Ghz and 1:1 is DDR2-800. Running at DDR2-1000 (not 1:1) is faster if your memory can handle it.

Well the electronics of a mobo can make a noise tho. It doesn't have to be a moving part like a fan or HD to squeal. I know my mobo makes a slight whine/buzz sometimes depending on what the system is up to. Not my first mobo to do it either. However I agree I don't think it is the CPU itself doing it, probably something like a coil on the mobo.

I've worked on electronics for years... a whine coming from powered electronic equipment is a very distinct, very disturbing noise for anyone who's done the same. It usually means a capacitor is going bad.

It might not be any time soon, but at some point (maybe during a power surge or a touch of the power switch) you'll probably hear a loud whistle and a pop. If you're computer doesn't turn on after that, you know what happened. They smell pretty bad too. 😛

Keep an eye on it, it's definately not a pleasant experience.

First: Check your PSU. They can squeal when draw on them is too great for them to handle. Even if it could handle the load before, it was probably just barely and something finally said, "screw this!"

Check motherboard thoroughly for leaking/bulging caps. The OP's mention of a fresh OS install indicates a hardware problem that may not be supplying enough power due to failed caps or even a mosfet. Examine every single cap on the board even if you have to dismantle your system, remove the mobo and have it in your hands.
