Question for the expierienced overclockers

[Greebo]

If it was me and it was 100% prime stable I wouldn't return it, and if you return it after they have stopped being made they will most likely send you one from their stock of replacements.

Shame. I was hoping if I hold out long enough I;d get a q9550

That's my dilemma though. I have a faulty chip capable of 3.8Ghz stable or do I risk a new, none faulty chip which might top out at 3.2Ghz like some peoples do on here.

If I had been on air, I would have returned it. I still might before it's warranty runs out but it will do for now

If thay have stopped making q6600 when I return it, what would I get as a replacement do you think since q6600 and end of line this quarter?

i think you will have a job exchanging a chip because it does not overclock to what you want.
intel and resellers only guarantee them at stock, at least that is the reply i get.

Yeah thats true, if it doesn't reach 73C @ 2.4ghz and fail with the stock cooler then how would this "fault" ever be noticed under normal operating conditions... that's what they guarantee perfect working condition at stock settings/temps.

That's the thing though, It would probably be stable reaching 73C @ stock speeds.

73C is 73C isn't it? are you saying its more likely to be stable at 73C at 2.4ghz then at 3.8ghz

The thing with my chip is it runs at 3ghz Prime stable at 1.31v @ 78C to get to 3.33ghz with most chips you need approx 1.36v, with my chip its only if I set 1.45v that it runs at 3.2ghz for approx 2hours albeit @ 97C, any less volts then that it fails rather quicker then that, I think its safe to say I have a rotten chip. I just tried 1.45v BIOS 1.36v under load @ 3.30ghz again and Prime95 fails instantly on 1 core before it even has a chance to get hot. Now the answer to this is always going to be more voltage as its not a heat issue, the thing is more voltage means more temp, so from what your saying there is a trade off point where temperatures start to affect overclocking stability.

No it wouldn't it would fall over. However, the big question is would it hit 73C on a stock cooler at stock speeds? Maybe not.

You just need better cooling

This reminds me of the time I got 2.4GHz out of my 2500+ barton - that was not enough so I got a thermochill 120.3 rad, 6 deltas , cpu block & eheim pump ... I got a whopping 2.55 GHz with that lot attached Who says that extra cooling (near on £250 worth) aint worth it!

So, I flogged that chip and got a 2500+ barton mobile --> 2.7GHz. So, I flogged that one and got a 2600+ barton mobile --> 2.85GHz @ 2.1v IIRC (2.8 24/7 use). STICK I Cried !! On air that last chip will do 2.5GHz but get a wee bit toasty ...

Now I got me a Q6600 that'll do 3.6GHz @ 1.35v for almost silent running I feel that I have had some luck after all I have benched it at 4GHz to get a 3dmark06 score and superpi but 3.8 is the comfort spot methinks.

mine drooped a lot with my 2180 (can't remember how much exactly). and it droops 0.1v with my q6600.

mine isn't the best cpu as it takes 1.4625v set in the bios for 3.42ghz (380x9) stable. cpu-z shows 1.36v when priming in windows. but it's quick enough for me.

Well as I've said the 3.85 was a kamikadze shot at 2.0v ... on air .
Managed to boot in windows, switch on cpu-z and coretemp just to see the temp hitting 85c and shutting itself down .

I need about 1.5v+ to hit 3.2ghz ;x. I guess I don't have the best chip out there. But anyways I just bought this to play around with, probably gonna end up getting an E7200 soon for same reason and E8600 when they come out.

Not planning on any bigger upgrade unless I got enough cash for nehalem, 12gb ddr3 and Super RV770 x2.
