Greetings.
I recently built a budget PC with the following components:
Abit IB9 P965+ICH8
Core 2 Duo E4300
Wintec Ampo 2 X 1GB DDR2-5300
So far, I've had everything running at stock. When I put everything together, the memory defaulted to 200MHz rather than 266MHz so I left it alone for the time being. CPU-z is reading 2T for the command rate. I plan to start playing with overclocking now that I've had more time to dedicate to it. However, I have already noticed a couple of unexpected aspects of my system
First, I ran SiSoftware Sandra's Memory Bandwidth test and I am getting a dissapointing:
3550MB/s for Integer Buffered iSSE2
3544MB/s for Float Buffered iSSE2
Running at 200MHz, dual channel, the theoretica bandwidth is 6400MB/s so I was dissapointed to get a little more than half of this.
Is this bandwidth to be expected in real world for this system or are there some things I should be looking at?
The second issue I am having is that the CPU is showing 41 to 42ºC on the included Abit EQ motherboard monitoring application. My system temperature is showing 30ºC so my difference is ~12ºC. When I read the reviews for the processor in newegg, many people quoted temperatures of a few degrees over system temp with stock cooling. SpeedFan v 4.32 shows the CPUat the same temperature but shows Core 0 and Core 1 at ~26º which did not make much sense to me as I thought junction temperature was supposed to be higher than that of the cores.
Is my temperature normal or do I have a hotter than average CPU?
I am planning to do some mild overclocking (33% or so) but I've read elsewhere that it is not advisable to run Core 2 Duo's over 50ºC. If I am already at 42º and core temperature is anywhere near linearly proportional to clock speed, running the e4300 at 266MHz will easily push my CPU temperature over 50ºC, let alone push the overclocing even further.
I will appreciate your advice.
