I overclocked my 3770k to 4.8GHZ stable @ 1.325v, been running great for 2 months, now all of a sudden I was getting lots of crashes in BF3 so I primed again and BSOD near enough straight away...

Any real reason behind this, now having to test at 1.335v but I dont want to increase the volts as im hitting around 85c on all cores now.
 
Maybe the weather is pushing your temps higher than they were 2 months ago, pushing it into the unstable band?

During the height of last weeks heatwave I was getting issues with mine, even though its rock solid every other time of the year.
 
I get crashes on my sandy if it goes in to the 80's, so yeah as above I'd say the temps you are hitting are introducing instability

ivy's are known to have issues with heat due to the rubbish TIM they've used on the heat spreader instead of soldering like they did with past gens

Crashes in what? Never saw a Sandy or Ivy crash due to heat in the 80s.

fails in IBT/Prime or blue screen in BF3

by 80's I mean high 80's
mine runs mid 70's usually with occaisional spikes to 80-82

3930k 1.35v @ 4.5ghz, if I increase speed or voltage I start getting spikes to near 90 and instability - if I can keep the temp down below 80 then it runs stable @4.6ghz, but above 85 is starts failing IBT

water next week so will try again then
 
Done some priming and temps are up about 5c, @ my 1.325v overclock my max temps used to he around 85, now they are over 90, so I cant increase voltage to make things more stable as temps are to high and decreasing wont help either.
I might try reapplying thermal paste and resitting headsink, will this help?
 
Reseating might shave at most a couple of degrees, but not as much as you need. Needs better cooling or clock it down a bit.
 
O.k increased volts from 1.325 to 1.350 and all is stable again, though temps are now hitting low 90's with the case closed, to high for my liking even though the max temp for this chip is 105c. I know with BF3 a CPU instense game the temps wont even hit 80c, so I think ill sort my case fans out and go from there.
Strange why I need the extra voltage though, maybe a MB bios flash might help?
 
Not that strange - 25 mV is pretty small. 2 months ago you were just the right side of the line, after 2 months of use perhaps something has changed in the chip(?) or some part of the mobo isn't doing its job as well (I'm not an EE). In any case, it's just gone over the line so you need the next voltage up. Maybe :p

Why not just clock it down to 4.7 or 4.6? You won't notice and the voltage you need will be a fair bit lower. Save you money too.
