SOS!! Unable to OC E6300 even slightly

[catatonicmoron]

Sorry guys... this is a rewording of my previous post... i dint get many replies but definitely need some expert opinion here

My rig is:
E6300 on stock HS and fan
Asus P5b
EVGA 8800GTS
OCZ Gold 5400 1024x2
Antec Basiq 500w

Without OC... it ran Prime95 on torture for 3+ hours and runs oblivion everyday on almost max settings without any problems..

I decided to try some minor overclocking and set the FSB to 285 (from 266) to get 2.0 GHz. When i rebooted there was a HUGE "TRRRRRRRRRRRRRRRR" noise as ..... i immediately switched off the power and turned it back on. While POSTing the bios reported an OC fail and rebooted fine on default settings. I tried this once more and isolated the sound to be "near" the processor before chickening out and switching off...


When i initially built this rig... i needed to remove the HS as the DVD drive wasn't fitting in easily ( got it after i assembled the othr parts). I work long hours so i decided to run the machine in the weekend after i got the thermal compound (as the stores are really far off). But there was an emergency (another long story) and i HAD to use my machine.... so i installled the HS without the compound. I braced myself and booted the comp and watched as temps climbed to 76 idle and touching 81 max once or twice before coming down to around 77. I ran the comp like this for 4 hours each for 3 days straight before i got Arctic Silver 5. Now idle is around 45 and full load is around 50 (not cured yet).

Someone told me that maybe the fan is now unbalanced.... but since it works fine without OC... can that really be the explanation?
Could it be that it reached thermal maximum and that was the warning noise?
Is it that one of the cores is busted coz of me running it so hot earlier? How do I test both cores on prime95 or any other software?
Can I get a replacement from Intel saying that i cant OC (even though warranty is void after OC)?


Thanks and appreciate any help.

I don't think you can get a replacement from intel as you said... you o/c'ed it and if anything, the error was user error, not hardware failure.

the question is, what did you do those days that the temps were hitting 81? because if it was around 76-81 idle, i couldn't guess what the temps would have hit if you had put a load on the cpu's.

also, i'm surprised the cpu didn't throttle at those temps unless you disabled it in the bios.

 

[catatonicmoron]

The temps hit 80 on load.... but i did not load it during that time knowing that it was too hot. But still... how can it work fine at full load without OC and make some weird noise at 20 fsb more? Also... i'm not sure the noise was from the procesor... could the problem be with the power supply? btw... I did not disable throttling
Thanks

Why would you run a cpu with no thermal compound between the cpu and the heatsink?

The stock heatsink comes with some marginal goop on it and you can alway run over to Radio Shack, Best Buy, Office Depot, etc in a pinch. Heck, even a dab of toothpaste would work in a crunch.

I guess I don't understand.

IMO you might need to re-install your HSF with some thermal compound before you continue to do anything else AT ALL. You shouldn't even be thinking about overclocking with temperatures like those.

 

[Wik]

What did you have your memory set at when you overclocked? When it was making the "TRRR" noise was it showing a post on the screen. Sounds to me like maybe you were hearing your motherboards error signal. Long beep meaning overclock fail. What voltage do you have going to the memory?

 

[catatonicmoron]

All my memory settings were on auto.....

According to intel... max temp is 85 after which throttling/shutdown happens
So i ran it at around 75/76 and was v wary. It hit 80 once... but thats it.

and Cheex.. i have reinstalled the HSF with AS5 and temps are now arnd 45C. I live in the middle of nowhere in india and getting to shops on time after work was not possible... (no BestBuys where i stay )

So there are only two things... one is that somethings busted in the proc coz of the heat... and two is that nothings busted and theres some other issue causing the noise (i'm a newbie at OCing.. but did enough research before attempting a slight one)

So basically i need to know how to determine if my proc is ok... esp if oblivion and prime95 torture test work great.....

And Wik the sound wasnt a beep... it was more like as though a cable was stuck in the HSF (which it wasnt of course)

Thanx a million to all for ur prompt replies. Really appreciate it

You ran it w/o thermal compund! /SLAP!

 

[KingstonU]

I agree. I've never, ever heard of someone not using a thermal paste.

What a way to waste a few hundred $$$. I'm sorry but if you have so much money that your happy flushing it down the toilet you might as well give it to me, or even better, to some poor people over there in India.

 

[Rinaun]

Usually im nice, but you ran it without TIM. Probably one of the stupidest things I have ever heard. WHY would you risk the money? If you needed it in a jam, SOMETHING is better than NOTHING. Common sense for the win.
.

 

[catatonicmoron]

a) the temps were within 10C of throttling/shutdown levels
b) The rig works great without OC... and we still dont know if it actually is damaged and thats wats making the noise during the OC
c) id rather not put toothpaste coz its not "better than nothing"
d) I wouldnt hav run it if it wasnt worth much much more than $180 to do so
e) This was my first rig... didnt know that u need to replace TIM everytime u take out HSF.. which is why i dint use it inititally after temps hit 60C

 

[gramboh]

Why would Intel give you a replacement? OC is not a feature of the CPU.

 

[F1N3ST]

If it was an emergency use gum or Die-Electric grease which is all thermal compound is.

You might be suprised to see how well toothpaste works.
Toothpaste Better Than Artic Silver 3

:Q I had no earthly idea...

Seriously all, his first build, didn't know about importance of TIM, screwed up, and now learning from it. I remember building my first PIII computer - I never changed the heatsink out, and if I would have had to, I'd be too scared back then to do it.

Back to your points, catatonic:

You probably shortened the life of your CPU. It may not OC due to a manufacturing defect - but it runs at certified speed, so Intel had sold you a good item (warranty does not apply).

a) Anything higher than normal will age a processor, not necessarily kill it.

b) If it runs perfectly, it ain't "damaged." Can you liken the sound to something? Buzzer? Vibration? The fan wouldn't be affected by an OC. The fan could, however, be defective and it manifested itself when it had to spin awfully fast to compensate for your risky move. It wouldn't explain that you get the sound upon boot, however.

c) Holy crap... I've got a fallback plan now, in case I run into this situation...

d) NP - again, first build, and we have no idea what the emergency was about. If you can quantify it as >$180, then you broke even.

e) It's still shocking... but learn from it.

Try a stress test at normal clock levels and watch your temps/errors. If everything's normal, you're fine - just don't OC without TIM anymore. And pls give more details on the boot up sound, as well as any other indications your comp gives you.
