OC'ing Core 2 Duo/Should I?/Testing?

[shovenose]

I'm trying to overclock the Core 2 Dup E6600 in my "bedside PC"
It's got 2GB DDR RAM and a 250GB HDD, a 300W Seasonic PSU, and a ECS motherboard with (I think) a G31 chipset...
Problem is, while my cheapo ECS has BIOS settings for the frequency, it has NO VOLTAGE CONTROL!!!
The stock is 266MHz, the multiplier is 9.
9x266= ~2400MHz
The question is: how high can I expect to get, as far as GHz? And how the heck do I test it (no Prime95 in Ubuntu lol).

Re: OC'ing Core 2 Duo/Should I?/Testing?

Prime95 will run through wine in ubuntu. I've done it lots of times.

I'd just bump the FSB up to 333 (2.97GHz) without changing the voltage and see if it likes it. If not, just forget about it. ECS boards are absoloute junk and don't overclock well.

Hey that board was like $30 new from Newegg :P so don't insult it... you know me I always buy cheap crap...

Anyway I'll try your Wine idea :-)

cheap cheap=suck suck.

you got what you paid for. perhaps less.

Re: OC'ing Core 2 Duo/Should I?/Testing?

So far I am at 300fsb it runs fine (haven't done a stress test yet tho)...

Re: OC'ing Core 2 Duo/Should I?/Testing?

older versions of the E6600 can be taken to 3.4ghz before voltage bump, 3.6 or higher with better cooling.

Your motherboard will hold you back when you hit the fsb wall and does a no-boot scenario. Usually the chipset or memory will be the problem.

Take it 3.2 and if it remains stable then 3.4 to 3.6 and if you're lucky go for 4.

Also there should be a linux version of prim95 in the ubuntu repos or on mersenne site.

I have done 3.5 out of a 1.8 before I will push any processor in a desktop it takes a while to hit that sweet spot what i do is clock it as far as i can and get it stable then i back it off one step. Thats just an old habit from overclocking durons the processors seemed to last longer and so would the boards especially doing voltage jumps.

Re: OC'ing Core 2 Duo/Should I?/Testing?

It didn't boot at 333. But since it was booting at 300 I will try somewhere in between.

Re: OC'ing Core 2 Duo/Should I?/Testing?

you hit the wall with the cheap board.look for something better.
is it oem or ecs?
oem ecs boards often have stripped bios.figure out what it really is and flash.
but you are still pushing a chain.

It's ECS. Got it from Newegg.com

Extremely Cheap *you know what goes here*

Re: OC'ing Core 2 Duo/Should I?/Testing?

I know. But I bought something at the same time I bought the mobo:

That's OK- you did replace it before it fried any of your systems... right? I hope??

Oh 'Deer' me- some people make things too complicated. Why use a cheap POS to power everything when an "MOT" is a more 'direct' approach. The best part is you don't have to wait three months before it kills the system...

Don't push Vcore too high- electromigration will 'slow-cook' your CPU.

The problem with my ECS crap is I CANT CHANGE THE FUCKING VCORE!
Sorry I'm not angry at you just me for buying this cheap piece of shit motherboard that belongs in an eMachines/Gateway where it can live its days with other crap components...

And yes I replaced the Coolmax after about 3 months...

Enjoy. Don't have a silver conductive pen? Just use a regular pencil.

If you re-flash the BIOS and end up being able to change it, I'd at least put a voltmeter across Vcore and verify it.

Ya don't want to have 1.5V when you think you've got 1.35...

I understand completely after my ASROCK adventure. Believe me, I know where you're coming from! The only things that surpass it are the 'Adam computer' and the "Rednecked computer.' I should post those stories in their own threads.

Naw. How 'bout in a nasty, POS, fugly HP/Compaq?

That's not what I expect from you! Where's the guide to change the feedback resistors in the VRM to get any voltage we want?

Funny thing is, it would be possible if it wasn't all SMT...

Both my HP and my Compaq with ASUS mobos and NVIDIA chipsets with TINY heatsinks still work fine :P

How do I measrue that?

Re: OC'ing Core 2 Duo/Should I?/Testing?

If you're 'missing' any caps on the VRM output, you can 'cheat' and measure right there. Otherwise, you'll have to trace it out. Sometimes, there's a surface mount ceramic cap for Vcore, on the top of the board, that's accessible. You do not want to short the VRM, with 50-60+ plus amps available!
