Overclocking e5200

[GordonT]

MSI P45 Neo-F
E5200 (Wolfdale) running at 3831MHz (333 fsb x 11.5) voltage 1.38v
Corsair XMS2 TWIN2X4096-8500C5 G (4GB 1066)

Could not get past 267 fsb on 12.5 multiplier no matter what I adjusted. The memory is not "real" 1066, just good overclocking 800 chips. Main problem seems to be temperature readings of 42 idle and 65 at full load with a Vendetta 2 bolted to cpu. Have had cooler off twice to reapply thermal paste just in case. No difference.

That temperature is alright, 65 C at full load is still safe, just be careful not to let it get past 70 C, old oc'ers say that 75 C is the max temp that an e5200 can handle, I do believe them. If you really want to measure how hot your proc can get, run the linpack test which is similar to the intel burn test, OCCT has that feature. And by the way, your voltage is quite high, I think an e5200s max voltage is about 1.3625 v, higher than that, you will just shorten the life of that nice proc.

I ran the OCCT Linpack test for 1 Hour without errors and max temp of 78 degrees. Real Temp registered same but Core Temp consistently reads about 5 degrees higher at all times and gave 83 degrees. I ran Prime 95 on Blend for 3 hours last night with no problems also. Temps never got above 70 degrees on Prime. I managed to get my finger on top of the alloy casting enclosing the heat pipes on top of the cpu but it barely felt warm. The air coming through the cooler remains cool at all times. I will reduce the voltage to be safe as well as voltage on Northbridge. Originally I increased as much as I could to get my memory running at 1066 only to find that increasing fsb and reducing multiplier was only way to go. I have not tried increasing fsb yet due to temps being what they are, so there may well be more to gain. I have read that these chips can have temp sensor problems.

If the original poster is still around, the ACF7P is a great economy cooler. But you probably have reached the limit of your cooling capacity. You should be able to go higher with a better cooler.

I will try adding two 120mm fans and one 80mm fan to case to see if it helps as well as removing Vendetta 2 again and using OCZ Freeze Extreme this time to see if it helps.
I set everything back to auto and 200 fsb by 12.5 multiplier and ran OCCT and Prime 95 again to see how temperatures changed. Never went above 50 degrees on either with a minimum of 33 degrees. No problems with sensors, just my expectations!
