Bum core!

[dagger]

Hello, does anyone know what to do with a bum core? I have a Q6600, with one core fail Prime95 immediately at 3.8ghz unless vcore is upped to 1.6. At which point it holds at 5+ hours... but... it's 1.6

This goes alone with some strange heat readings: 67, 67, 65, 63. Final sturdy reading at 100% load, 3.8ghz, vcore = 1.6
What's with the 65-63 difference? How does that work?

There is something wrong with that core. I'd rather not burn off the other three cores to give that one enough juice. Anyone know any tricks?

I doubt there's any tricks to solve this, tough luck.

And for the temps difference, it could be due to many things, such as uneven spread of TIM or uneven surface.

Do you think it's serious enough to warrant taking out the cpu and RMA it for a new one?

Intel guarantees the cpu to work on stock settings. 3.8GHz is a bit off...

I suppose you can RMA if you want, but do they allow that? If it works totally fine on the specified settings, you mostly likely can't.

Man, do you even need 3.8GHz?

Good point. I'd rather not pull apart the machine at this point anyways. It's completely stable at 3.6ghz with 1.45vcore.

Still, there is no way for them to tell it's been overclocked. It didn't happen unless you get caught.

That's true, I suppose. But Newegg and most other places doesn't allow returns if there's nothing wrong with the cpu. That includes poor OCing, so either way...

How? So if I say it's unstable at stock, will they actually put it in a computer and test it? It's not lying unless they know it's a lie.

Probably not lol. I just checked newegg's return policy, you can return it within 7days or exchange it within 30days as long as the cpu isn't physically damaged. http://www.newegg.com/Info/ReturnPolicy.aspx#5

So I suppose you can exchange it, as long as you bought it within the last 30days.

Ah well, I'll just keep this one. 3.6ghz is good enough. That, and I'm too lazy.

...of course 3.6GHz is enough. Stop being greedy! I'm fine at 2GHz on my Q6600.

 

[acidpython]

2GHz? What did you do underclock it?

3.6ghz is more then enough i only pushed mine that high to see if it would run stable.

Yeah, a lot of people test their component limits, only to tone it down for everyday use.

 

[Evilonigiri]

Recently, I haven't been playing games, so I dropped the multiplier to x6 with 333MHz fsb for quietness.

 

[iluvgillgill]

i run my at ultra high fsb but at low speed!lol lowest 6X multiplier but with 400+fsb to ultilise memory bandwidth.

Which will make minimal difference compared to a higher CPU overclock.

@dagger: Dude, 1.6V for 3.8GHz is normal.

@all: Newegg has some nice policies. Most places in Australia won't allow returns unless faulty, or they will if unopened and within 7 days of purchase.

 

[iluvgillgill]

but if you run higher fsb with lower multiplier but at the same cpu speed.then there will be performance gain.
355x9<400x8 CPU will result the same but it will providemore bandwidth to the memory system.

I heard the performance gains is just in benchmarking and not real.

And people have done 3.8ghz at 1.5vcore before. It was just a little disappointing.

 

[Evilonigiri]

Higher fsb will give you a massive increase in performance in synthetic tests, but when it comes to games and such, there should be no difference. I'm not sure for memory intensive applications though.

 

[iluvgillgill]

if you say that then can you notice any difference with low fsb then?so its really upto the person who own the pc decide how he wants it.but just personal views we are giving on this forum.

Yes you will notice a difference with a low FSB, because that will mean a low CPU speed too, unless you have an unlocked multiplier. But if you paid for an EE chip, why would you run it at or below stock? :lol:

Well, cause the Energy Efficient cpu isn't efficient enough. Duh.

 

[iluvgillgill]

i think i left something out.if you run the CPU at same speed.difference in FSB wouldnt be notice in real life situation.

 

[randomizer]

Yea... that's what we were saying. There will be some difference, but nothing compared to increasing your CPU speed (and even that will only make a difference in certain applications. But you can't keep the CPU at the same speed while lowering the FSB unless you have an extreme edition chip. *stares at Evilonigiri*

 

[iluvgillgill]

i mean
500x6=3Ghz
429x7=3Ghz
375x8=3Ghz
333x9=3Ghz

the performance will be the same.but the memory subsystem will get better bandwidth if problem that need alot of memory to do the task.

 

[randomizer]

While that is true, a memory intensive application is probably going to be CPU intensive too. What do you run that requires so much bandwidth anyway?
