One problem... I've only used software to overclock before.
If someone else has gotten it to 4Ghz, is it as easy as copying their.. numbers?
Your motherboard is very easy to OC with. Below are the settings I would recommend to start with, then tweak from there.

I need to know your ram model. G.Skill produces many DDR2 800 kits.

Advanced BIOS Features
CPU Enhanced Halt (C1E) Disable
CPU Thermal Monitor 2(TM2) Disable
CPU EIST Function (Note) Disable

MB Intelligent Tweaker(M.I.T.)
CPU Host Clock Control Enabled
CPU Host Frequency (Mhz) 422
PCI Express Frequency (Mhz) 100
System Memory Multiplier (SPD) 2.0 (You want it as close to 800, but with your FSB at 422, it will be exactly 844)

System Voltage Control
DDR2 OverVoltage Control: +0.2v (default is 1.8v, but the ram can run 1.8v-2.0v accoriding to G.Skill)
PCI-E OverVoltage Control [Normal]
FSB OverVoltage Control +0.1v
(G)MCH OverVoltage Control +0.2v
CPU Voltage Control 1.30v - 1.35v (this is your CPU's vcore, it might need less then 1.35v)

Depending on what bios you have, you might have to press [CTRL+F1] in the main bios menu to access advanced memory timing options.




You need to download CPU-Z to check settings from within windows. The main CPU tab and memory tab are the important ones. Also use RealTemp to monitor your CPU's temp at idle and load. To put a load and stress test your OC, run Prime 95. All of these programs can be found in the downloads section.

Your E7200 runs on a 266 FSB, has a max VID of 1.3625v (which happens to be the max safe vcore) has a 9.5 multi, and has a max thermal limit of 74°C.

Didn't see there was a second page.
This is the RAM I'm using.

Well my E7200 is running at 3.8Ghz 24/7, I havn't bothered pushing it higher but I'm sure it will go higher.

Also, for gigabyte board you need to press CONTROL +F1 at the main bios menu to unlock the extra voltage controls in the M.I.T.

E7200 is turning out to be an overclocking monster rah lol

The E7200 is like a Small car with a 5.5 litre engine

I listed that in the previous post. It will unlock the memory timings, not the voltage controls. With the newer bios, it isnt needed anymore as they are now part of the main bios.

Also note I updated the previous post with ram voltage adjustments.


Final note, once you get the chip to the targety clock, try lowering the vcore while maintaining a stable OC.

So you would recomend the settings listed above, ok.
What do you meam by tweaking it? I'm kind of new to BIOS overclocking.

Pardon me if this is considered a thread Hijack (if so let me know ill start a new thread), however my rig is very similar to the OP's and so I tried Ericeod's suggestion for bios settings. (cept I left the CPU Host Frequency at 400 to get 3.8Ghz)

It posted, booted up Windows np, ran Prime95 for a couple of hours all good and stable, real temp said my temp never went above. (i forget actually...think it was something like 55 degrees)

cool everything is nice and stable, so I shut the computer off and go do other stuff, come back turn the comp on....no post...goes into bios, it reset everything...so I set everything up again, restart...no post.

so yea, I got my comp to do 3.8 one time, so i KNOW it can do it, but for some odd reason it won't anymore.

Any ideas?


Edit: I did a little reading around and apparantly these boards are having issues with the Vcore adjustment, seems the bios keep resetting the Vcore to its default 1.15v on reboot.

Hopefully Gigabyte will do something to fix this issue, for now I can only go as high as the stock voltage will take me which is 3.16Ghz, I guess that will do for now.

I wonder why the box that my chip came in has 1.25 volts max. Is running higher than 1.25 going to degrade it?

The specs I posted are from Intel's website and are current. I have not seen any issues from people running 1.3625v or less on the wolfdale or yorkfield CPUs (all 45nm CPUs). So I think you are safe to run above 1.25v and up to 1.3625v safely.
