E6300 - Bought a duffer?

Near Longleat, Raaaar!!
Picked up a used E6300 from a well known auction site. At stock it idles at about 47-49c and rises to about 54-56c under load (temps from Coretemp)

I heard they overclock well so I tried 2.4 and the temps rose from about 53ish idle to 65c+ under load using orthos. The thermal spec according to intel is 61c max and the cooler i'm using used to keep a q6600 under 65c at 3ghz.

I've tried reseating the cooler and reapplying the TIM but not much of a difference, maybe 2c or so.

Now, Have i just bought a duff chip which has probably been overclocked to an inch of its life by someone who doesn't worry about temps or are they OK to push above 61c?

The rest of the system it in is:
Abit FP-1n9
3 gig ram
Akasa AK-956CP cooler
xp
Xpertvision 8600GT DDR2
 
Check to see if the IHS is concave, the early 6300's had horribly concave IHS, mine did and after lapping it the temps dropped massively.
 
Sounds like a plan. Whats the best way to check? Was considering lapping it anyway as it was only cheap but wouldn't have a clue how to go about it. Any tried and trusted methods?

What he said - even the E6600 was quite prone to this - lapping mine dropped a good 10C off the temps.
 
If you are not comfortable with lapping, a thick dollop of TIM in the middle can act as a substitute to 'bridge the gap' ;) and imo works as well since i've had similar results with a lapped and non lapped cpu.

Not very good advice, the more tim you use the less heat transfer. If it was possible to have the IHS and cooler base so absolutely flat that no tim was required then you would have perfect heat transfer. tim when used correctly is for filling in the microscopic pores on both surfaces (less is more) not as a sandwich filling between the surfaces. My E6300 has such a small amount of tim that you cant actually see there is any tim, there is just a very dull sheen to the surface.

Theres always one, yes too much TIM can become an insulator but by filling the gap where there'd be almost NO contact otherwise you at least least get better transfer. I've done this with numerous cpus with concave spreaders and know it works no matter what your particular opinion may be. The last cpu i had this problem with was my L629B E6600, temps went from high 70s load to under 65C @ 3.6Ghz 1.375V, this was with an Ultra 120. Sometimes the orthodox way is not always the right w a y, so unless you know of a better way other than lapping...

p.s why did one of my ways get starred out? :D

Not sure if a 'thick dollop' is metric or imperial but to me it sounds a little to much. Its a second hand cpu, i doubt it has cost him much (maybe less than a 'dollop' of TIM) so i would advise lapping it. If it works great, if not then he can TIM it up with dollop after dollop of the stuff.
 
Well i did'nt mean dump a whole tube on it :rolleyes: . Why get like that? i and many others know this works, have been doing it since the advent of IHS'ed cpus and it works with proven results, much easier than lapping and i've found the difference negligible between the two methods, maybe 2-4C better with lapping and since its in the center it dosen't degrade over time, just put a bit more than you would usually focused in the center, done with this with PIVs, A64s, Opterons, Core 2/Quads etc.. btw too much focus is put on temps tbh.

If he is getting 65C+ at 2.4ghz and assuming his Volts arnt too high then something is wrong, what we dont know is how much TIM had been used originally and how much when re-applied. I tried the lots-normal-very little when i first got my E6300 and saw little change, i then lapped it (flapping as it had cost me 110 quid) and knocked the temps right down. I spose he's best off going for the 'dollop' method and letting us know how he's got on, if the temps are little different then id go for lapping, if that doesnt help then..................................sell it on the bay and get an E8400 :)
 
Any idea of what the VID is of the CPU?

When i had my 6300 i managed an easy 3.15Ghz with max load temps of around 66 degrees IIRC.

It could be that it is a higher voltage chip as standard so doesnt have the headroom for much clocking. Bit of a pain if it is though.
 
Well 2.4ghz is achievable at stock Volts unles his CPU is realy trashed so his temps are way to high or are just being reported as way to high.

Not a rule set in stone though, have had many a high VID cpu clock better than a lower VID one. current example right here atm a 1.285V VID Q6600 that won't even boot 3.6Ghz with less than 1.4v and not be stable until 1.48v while a 1.325V VID one does 3.6GHz on 1.4V stable and boots at 1.3375v, have had a B3 that does 3.6 on 1.4V :D
 
Just finished lapping the e6300, (and managed to sand the corner of my thumb til it bled...) and the results are impressive:

@ Stock its taken about 7c of the idle temps and about 4 or 5c off the loaded temp.

I'll let the TIM bed in for a day or so ( went down the less is more route) and then I'll start winding up the Ghz.

Thanks for the advice all, I can honestly say this is by far the most helpful forum for a budding overclocker who gets a bit lost. Cheers
