Have I damaged it?

Ok, I was OCing just a minute ago and I accidently booted with 1.45V Vcore and a +.100MV offset. I then got BSOD and then realised I had done that in the BIOS. Could this brief time maybe putting about 1.56V through my E6600 have done any damage to it, I checked Coretemp when I was at 1.45V +.100MV and it was at about 35 something, I'm now back at stock everything and it seems a little funny but I'm just a bit of a worryer, please put me at ease :eek:.
 
It'll be fine.. I've run my 6400 at 1.6v for several hours before when I was playing with it to see how far I could push it! :)

Still works perfectly to this day..
 
Personally, I wouldnt run it long term at 1.55V, but a few minutes, or even hours, no, virtually no chance of causing long term damage.

1.65V... sure maybe it works fine 24/7 but it will reduce the chips lifespan... Although that said.. most CPU's even abused overvolted, undercooled chips still last long enough to be slow junk that nobody wants anymore :).

Of course when abusing processors, original manufacturing tolerances come into play... one cpu might work for years abused, while another might blow after a few months, due to microscopic defects in the silicon.
 
Ok, thanks for putting my mind at ease. I am not going to run it at that, I was putting the Vcore to 1.45V and that should have been 1.35V with +.100MV but I set it to 1.45V and then turned on +.100 offset after without thinking. Obviously under load on startup it went to about 1.56V but it was only at that for about 1 minute maximum. I am having real trouble getting past 3ghz, I can do 3ghz with my memory on linked in sync mode running at 675mhz which is slower than stock at 800mhz. Will 675mhz memory affect performance in games, or will a 3ghz overclock more than compensate for it? If it is worth it I will run it at that, as really this is my first overclock and I'm just testing the water, and I've seen with my motherboard I don't want to have to spend ages tweaking, so I'm going to hold back until I buy a more expensive motherboard that will ovrclock a bit easier.
 
I always run my memory in sync, there isn't much performance gain in clocking the memoy further, except in memory intensive apps.

You may want to try 400x8 (3200mhz) this way you will have a higher clock, and the memory will be running at 800mhz, and in sync too :)

(may need a little voltage bump for this.. but should be easily achievable..)
 
Well thing is I have tried quite hard to get higher and it seems whatever I do it's not stable. and I mean it either won't post or boot into windows and if it does it freezes pretty quickly without even stress testing. I've gone to 1.45V (1.35V +.100MV) and it still hard to get it to boot. Only thing I haven't changed is NB voltage which someone has said to do but I'm not sure what to, and also what is the stock NB voltage for my board, I asked in the P5N-E thread but as soon as I did the thread died down again. Basically best I could do was 3.03ghz (1350mhz, 336x9) and memory linked and sync at 675mhz and stock timings, stock volts apart from 1.35V with +.100MV Vcore. I did a 10 hour stress test, 2 instances on prime95 doing small FFTs, temps were 52 after 10 hours, and no errors.
 
Which voltage, Vcore? And your saying 400mhz, so 1600mhz FSB? That is what I was aiming for so I could get memory at 800mhz but it just took me so long just to get 3ghz stable, I knida gave up.
 
im saying turn the multiplier down to 8 instead of 9, and up the FSB to 400, thus 3200mhz, but yeah, the vcore may need a bump, and i would try increasing fsb voltage or nb voltage or both a little.
 
Well there's the problem, I was advised to up my NB voltage, but I don't know what stock is for my board, it's on auto now and I have settings on like 1.3XX to 1.7XX, and from what I know about Vcore, you can select a volatge less than stock (seeing as various chips need different voltages) but can you go lower than stock volts on a NB or is the lowest setting stock? I asked in the P5N-E thread what it was after someone told me to raise it but no one told me the stock for my board. Thanks for the help.
 
chuck it to 1.5v and see what temps it's running at, see if it helps. I assumed to lowest setting was the stock voltage tbh (on my 680i board, it tells me auto, and then what the actual voltage is, which is always the lowest option...)
 
Ok thanks, and how do I check the temps, speedfan? I get readings on speedfan like this:
Temp1:38
Temp2:37
Temp3:24
HD0:33
Temp1:40
Core 0:29
Core 1:31
And that's on stock at low CPU usage (like media player internet and speedfan and some minor apps in background). Which is the NB temp? BTW I have 3 fans, are the first 3 temps readings from those fans or just probes on components in my PC monitering ambient?
 
i wouldn't u se speedfan, it's notoriously innacurate when not setup correctly.

For cpu temp, use intel's TAT or coretemp, as for the nb temp, use the software that came with your board, or everest.
