BSEL Overclock my e4500 Dell (g33)

post #1 of 16
Thread Starter 
I am trying to overclock the c2d e4500 in my Dell. I've done some overclocking in other pc's in the past, so I know the basics, but I have never done a c2d, and always did it on motherboards with overclocking features. Unfortunately, this Ã*s a c2d, and this mobo does not have any overcloking options, so, I need some help with it

I know how bsel modding works, you'll have find out some connections using the information given by intel datasheets...done that, I know which pins to connect in order to get either 266mhz or 333mhz (instead of 200mhz).

I tried it at 266mhz without any further modifications, it stopped directly after POST (just before the vista loader). So I guess that's a problem with my vcore being too low. in order to bsel my vid I first needed to know what the current vid was, but it wasn't listed in the bios setup. I found out that coretemp shows the real vid instead of the vcore with it's fluctuations (like other apps do). But coretemp showed me that the vid was already as high as 1.325 . As for what I've read, most e4500 have around 1.2 as default? .

Specs:
Foxconn g33m02 (up to 1333mhz)
2GB ddr2 667mhz (samsung)
e4500 m0 (with arctic pwm fan)

30 degrees Celsius Idle
50-55 degrees Celsius stressed (orthos)
VID = 1.325 (coretemp)
Actual vcore = ~1.280 (cpu-z)

What should I do to get 266 or 333mhz fsb? How far can I go with the vid?
And one other question, with bsel modding, would isolating pins so they have no contact with the mobo have the same effect as connecting them with the vss? (it would be a lot easier)

Its a Dell

And teh effort involed in bsel OCING is not worth it.

Dell usually lock their BIOS so that it can't be oc'ed. Don't brother.

Im with everyone else, your playing with fire....

I have an e4300 w/msi p965 neo on my second pc, tried the pen mod to post at 1066 and it wouldnt stay stable, no way to increase voltage so i removed it and it runs at 250 FSB..

You can prolly find a GA P965 DS3 for 50$ or just go with the GA P35 DS3L for 89 at newegg, you'll be able to pull 3.0 with stock cooling on that chip...

The bsel mod does work and in the right conditions is worth the oc. I did the bsel mod to my E4300 and was using a Biostar P965PT.

The thing is, it doesn't seem to work successful on all mb, at one time we had a list around here that showed the mb's that would use it with out issue.

btw, shouldn't require higher vcore than stock with the bsel mod, and having a 1.325 vid isn't a bad thing just means that particular chip is vcore hungry.

Your best bet is just dumping that thing Dell calls a pc and transplant most your hardware into a new case and mb.

I understand you don't really like dell pc's, I don't either, except the price.
But what you tell about it not being possible is just untrue, the mobo I have has been proven to work with bsel modding. I don't really need the oc, and I don't care if it does not work. I want to do it, just for the fun of it. As with bsel modding, memory or mobo does not matter (as long as the mobo supports the higher fsb), dell has nothing to do with it, just the cpu has. So please do you have an answer to my actual questions? 1. can bsel be done by just isolating instead of connecting to vss, 2. what vid range is acceptable for this cpu

what up Jazzle, Guess i have a question for you? What options do you have in the bios to adjust your Vcore.

(didn't mean to be rude, english is not my first language )

I have none, but with bsel I can get it anywhere from 1 to 1.5v (in really small steps)
post #10 of 16
If i were you i would shoot for 1.35V then , I mean unless you want to painstakingly figure out the exact voltage it is stable at. I would say 1.35 would be a safe bet or safe start rather. Get to it !
