How much voltage do I need? E7200.

post #1 of 36
Thread Starter 
I've been experimenting with voltage, and got it to boot at 2.6Ghz at 0.9. But it seems like it requires a LOT more voltage to do 3.1Ghz (1.07).
I've been trying to OC it to 3.5Ghz or even 4Ghz, how much voltage do you think I would need? I tried inputting 1.25 (max for the core) but that didn't work! Realistically, what is the maximum amount of voltage I can put in without reducing the life of the chip? What numbers would you suggest?

1.25 is not the maximum for the Core. I would stay under 1.35v though. You might need to go higher for the magic 4Ghz though.

Well, what's weird is, I'm running a CPU intensive application (pcsx2), at stock 2.5Ghz it seems to work fine, but when overclocking to 3.1 (333) it freezes? Is this normal?

Might be a memory problem.

Nope, I ran a memtest and it seemed fine, does the FSB effect the memory? Is this something I can fix by adjusting my FSB to "fit" my memory?

Here is the specs for you chip.

You may try to bump up the nb to 1.4 and/or bump up the ram voltage.

Because your using a P35, the FSB and RAM speed are linked, as you overclock your CPU, you overclock your RAM at the same time. The upside to this is that as you overclock, you only get better bandwidth with your RAM, the downside is that you have to overclock two things at once which causes you to have trouble figuring out what's not working right when something goes wrong.

So what do you suggest me putting my FSB be to properly "link" the RAM?
(NOTE: I havn't been getting any BSOD's or freezes in other applications.....)
I ran SuperPI, and that returned good too.

It might just be your application.

Your RAM is automatically linked to your FSB, you can't unlink it. Only NVidia and ATI chipsets can unlink their RAM.

Ok, but would changing my FSB fix this?
