How does this look? About an hour into running Prime95.

Its a step in the right direction but the temps are a bit high for an overclock to 3.25Ghz,
99% of the E5300 CPUs on this forum can hit 3.6Ghz and get around your temps,
My E5300 has a max temp of 58 @ 3.5Ghz after 8hours of Prime95 testing
so maybe you need a better case ventilation/cooling or you are giving your CPU more Voltage than needed
as a general rule, @ 3.25Ghz to 3.5Ghz, your bios Voltage
should be between 1.298v and 1.312v max
1- Whats your V-drop in CPU-Z and what is your bios V?
2- What motherboard are you using?
3- what are your settings for MCH v and CPU Termination?
4- do you know that your CPU will be faster if you lower the multiplier and increase the FSB speed? example 10.5x310FSB is faster than 13x250 because you are increasing your CPU's Bandwidth by increasing the FSB speed
5- you said that your had a crash when you set your FSB to 270, but 270x13 = 3.5Ghz and you may need to apply more voltage to your CPU, try to set your CPU v in the bios to 1.325 or just a bit more until you get stable OC, a crash a 270 doesn't mean that you hit your CPU's limit, in other words, i highly doubt that your FSB wall is 270 cause the E5x00 hit their FSB wall somewhere between 320 and 350, but the only way to hit an FSB wall @ 270 is if your MB is really..and i mean REALLY crap..
For example, I have a v-drop of 0.05 and a v-droop of 0.03
So right now i am running the CPU v in the bios @ 1.312 so my v-drop is 1.26 and a v-droop (under prime95 stress testing) of 1.23,Edited by omari79 - 1/28/10 at 7:21am
