Hey guys,
Looking for some advice on my older system. I'm currently running this system:
Pentium D945 3.4Ghz CPU (4.5Ghz OC)
Abit IP35 Pro motherboard
6gb OCZ Reaper DDR2-800 Ram
ATI Radeon X1650 256mb graphics card
650w PSU (Only an eBay one mind)
For cooling i'm using a Prolimatech Megahalems with a 120mm sharktech fan, and I have another 120mm inlet fan at the front blowing past the hard drives (I have 2, 1 normal hard sata, 1 Western Digital Velociraptor, which is primarily the one I wanted cooled as its a 10k rpm drive).
I've managed to overclock my CPU to 4.5Ghz (267Mhz clock, 17x multiplier (locked), 1.45v Vcore) and on idle I get a temperature of around 43 degrees at the CPU. With Orthos running a CPU stress test, I hit 53 degrees which seems okay to me.
Now my problem, mostly for lack of knowledge. In my uGuru utility window, these are my low-use temps:
CPU 43 degrees (High limit 75)
System 36 degrees (High limit of 55)
PWM 65 degrees (High limit of 80)
Now, to me they seem okay, however if I set Orthos CPU stress test, this is what I then get in less than a minute (50 seconds roughly):
CPU on average 56 degrees
System 36 degrees
PWM hits 80 degrees (The high limit)
As soon as PWM's reading hits 80 I get a warning and I shut it off, i'm new to overclocking with only limited knowledge and would like my CPU to live a little longer! However, I said my problem was lack of knowledge - What is the PWM reading? In my limited knowledge I thought PWM controlled my CPU fan speed if I had a 4 pin connector which I don't, I have a 3 pin connector and my uGuru utility controls both my fan speeds. However something is rapidly heating up so something isn't getting cooled and I want to know where i'm getting toasty!
So to summarise, what is the PWM temp reading and why is it shooting so high so quick? I can't even really perform a stability test at the moment though I haven't blue screened yet! I will mention now I plan to get a ram cooler soon (probably a zalman with 3x60mm fans) if that is what the PWM reading refers too.
Sorry for the hella long post guys. I haven't played around with OC'ing much, pretty much hit 4.0Ghz stable and left it. Bored tonight I got 4.5Ghz which pushed me from a 5.1 rating for my cpu to a 5.9 and made me all excited!
