How should i go about overclocking E5200


Apr 12, 2009
here's the components that i have:

CPU: Intel Pentium E5200 @ 2.5Ghz (Idle @ 24C/System @ 35C)
RAM: Mushkin XP2 8000 Redline 4GB Kit w/ OCZ XTC Cooler
GPU: Sapphire 512MB HD 4870 Toxic Edition (820MHz/1200MHz Idle @ 52C/36% Fan Speed) is this ok?!?
HDD: Seagate Barracuda 7200.12 500GB x 2 Running RAID 0
HSF: Scythe Orochi 10 w/ Scythe S-Flex 120mm 1600rpm Fan
PSU: Anteq 500 Basiq Power
Case: XClio A380PLUS w/ Scythe 120mm x 38mm 3000rpm Fan for Exhaust

so after deciding i wanna run RAID, i kept the ASUS P5Q-E instead of the GIGABYTE GA-EP45-UD3L (still trying to sell it btw), but while i was using the EP45, from the EasyTune 6, it was stable @ 2.97GHz, then i tried playing around with the settings, no luck on further that i've switched back to the P5Q-E, i tried just playing around with the FSB and vCore, it won't even boot up at all at any settings, so am i doing something wrong? and how should i go about overclocking the RAM (cuz the board only recognize it as a pair of 800MHz RAM)?

what's the max voltage that i can use on the E5200/RAM? 1.5625v CPU/2.1v RAM?

should i just leave it as AUTO for settings like: CPU/NB GTL Voltage Reference,CPU PLL Voltage, FSB Termination Voltage, NB SB Voltage, NB FSB, etc.

what are people's max stable overclock speed from the components that i have? (i saw some people online can reach over 4GHz just on air-cooled)

should i just grab the ASUS P5Q-Pro Turbo for easier overclocking? would it make a difference since they are just the same series w/ different add-ons?

and is Dual GB LAN useless in a home setting? (i heard in order to take advantage to it, you gotta have 2 ISP lines)


Check out the excellent overclocking guides among the Overclocking Forum's stickies.
The Intel datasheet for the E5200 series will tell you max voltage (which I'm guessing will be something like 1.4V), and Mushkin can tell you max voltage for your specific RAM model.

+1. Start in the BIOS and go slow, don't jump into a large overclock and expect it to be fully stable. Some chips are lucky some aren't. But usually the E5200 is a great overclocker.
