Are you sure that 3.2 is as high as you can go with that voltage? Then again mine has the 1.1625 VID which people have led me to believe is really good. I dunno, just trying to give ya some more hope. Keep playin' around and maybe it'll turn out better. It's taken me a few weeks of random messing to get the clocks I've reached so far. I've cursed at it, punched the desk, swore I was gonna throw the whole system in the garbage... but hey, it was all worth it!

Really, nowhere near 1.45V, worried about going over 1.4V... Where did you guys get this info? Cause I saw PizzaMan and Walnuts say the opposite thing.
As long as you check your temperatures you should be fine. I've seen a lot of people running on high voltages, I have yet to see a guy coming here saying he just ran the E5200 for 6 months on 1.4V and it blew up.
Sure they are around, somewhere, but they're outnumbered by the people still running strong.

You mean VID: 1.250V ? Cause thats the amount of voltage that the Intel factory said it needs to run on, and will always be 1.250V (unless you mod that )

Check out HWMonitor if you really think CPU-Z isnt working. Cause it is CPU-Z (the best). You're sure you dont have SpeedStep enabled or something? I even had a cheap-o motherboard with a 915!! chipset that worked, that's almost ancient. (and was cheap, really cheap)

I've tried every voltage adjustment possible to try, it wont go higher without some mean Vcore. Its ticking me off, something has to be holding me back.

I've been giving my chip 1.42v for a few months now. It's running fine. If you'll go back and look into the history of this thread you will notice that these chips CAN handle 1.4v+ if you can control the temps. I didn't see any chip degrading until I push her past 1.6v, but I'm not going to recommend you do that.

Yessir, BSEL mod'd the voltage cuz the cheap-o mobo doesn't have voltage adjustments. That would explain the snaff-u.

But, as you can see from the screenshot, both Orthos & CPU Rightmark are reporting 4.0GHz in WinXP, so it's probably a MSI BIOS vs CPU-Z thing.

How long do you think it would run at 1.5vcore?

I don't know. Intel's spec say absolute max is 1.45v. I've been running over 1.4v for about 6 months now and I'm not looking back. I ran 1.46v for a couple months.

I would guess 1.5v would run fine if you can control temps. It would prbly start to degrade after a few months. Though, this is a $70 proc. Braking it gives you a good excuse to upgrade.

Thinking about starting a dead CPU thread to collect data on what temps and voltages have actually killed chips. I've personally have yet to kill a chip due to over voltage. I have killed one in a no IHS experiment. Heat sink wasn't touching die.

With all due respect to PizzaMan and Walnuts, I will probably personally err on the side of caution with this. As you can see from the attached datasheet from Intel for the e5xxx series, it clearly says 1.45V is the maximum voltage acceptable for this chip.

While I understand thermal considerations are key, there are MANY other things at play other than just temperature when you up the voltage. Given how tightly packed these transistors are with the smaller die, more power will more than likely have more implications than just temperature alone.

I am not an Intel engineer, so aside from this spec from Intel, I cannot comment more on the topic. But, from back in the days when I use to overclock all the time and "push the limits," overclocking was more an attempt to take advantage of the voltage range available and spec'd by the CPU manufacturer. It seems that now, however, it's wholly acceptable to go way above and beyond those specs as long as the "temperatures stay ok"... something I guess I'm just not ready to buy into.

This is why for me, I'll try to give myself a bit of cushion and stay well under these Intel published Vmax numbers... at the end of the day, if I was only able to hit 3.5GHz at 1.35V, I'd be content as well.

Yeah I know that diagram.

But that isnt what I meant. I was more referring to user experiences. I know Intel's specs for the E5200, but regardless of that, Ive seen a lot of people going over it for longer periods of time. Well not 1.45V, cause I think we can all agree that isnt really smart for a 24/7 overclock, which most people try to achieve. But 1.4V on a 50% OC, running 24/7 isnt really shocking.

To say you should be nowhere near 1.45V, or like BlankThis worries going over 1.4V, better yet, 1.46V will fry your chip within a year, is wrong. (I could've misunderstood that part of his post though)
