Nah...and overclock.net isn't really a great resource...
I know but more people post there so if I'm looking for other's people experience there are not many substitutes, xtremesystems has too few people who are actually interested in stable overclocks instead of LN2 benchmarking
most forums either have lots of people where 60% seems to have no clue what they're talking about, or only a few people with lots of experience who usually don't even trust each other lol (watercooling scene is even worse :\ )
IBT uses the same Linpack files that LinX uses right? P95 custom blend with lots of RAM enabled did seem to stress out the IMC enough in my case judging by the crashes when setting the RAM from 2T to 1T
1. rig is built, overclocks to 4.5 fine (IBT/P95/gaming) for months (not a single crash)
2. watercooling goes on, 4.5 runs fine (IBT/P95/gaming) for a week, then I continue overclocking and reach
3. 5GHz at high voltage (1.45v+), runs stable(IBT/P95/gaming), then doesn't after ~5 days (BSOD galore)
4. now the same
4.5 setting from 1 and 2 BSOD's
within 20 seconds (P95/gaming) D:
5. 4.5 (and any other speed) now needs more voltage than previously to remain stable.
Temps have been higher (summer) and lower (open windows at night) but the only thing that works is more voltage. Only thing I haven't tried is upping one of the specific voltages (PLL and so on) in the bios, but that would also be upping the voltage right
youcantexplainthat.gif , maybe at the 5GHz+ extreme spectrum but not for what used to be a simple 4.5GHz overclock that had been stable for months (most of the gaming was Bad Company 2 and some Witcher 2, both love CPU power). Same profile loaded from bios as well, and it really went from a week of stable stressing/gaming at 4.5 to crashing within 20 seconds of anything mildly CPU intensive getting loaded, with just those couple of days high voltage 5.0GHz in between.
Could be CPU, could be motherboard, all I know is I was very glad it didn't totally die on me as I bought the CPU abroad because continental Europe was out of stock for the first 6 weeks of Sandy Bridge launch
I've just decided to stick to 4.8 these days ... also just did a 20-pass run of IBT 2.52 at very high 8 threads, perfectly stable as well.
