Im quite new to the overclocking world... last night i OCed my Core i5 2500k to 5ghz at x50 multiplier @~ 1.45v-1.5v, temp was between 66 and 70 defrees C, however it was ver unstable, so i stepped down the multiplier to x47 and v core to around 1.36~1.38.. Aida 64 stress test runs fine with no crashes/ hangs.. etc but when running prime95 torture test.. guess what.. BSOD.. below are my specs
In my opinion i'd drop your OC down to the mid 4 GHZ range. I am sure 5GHZ is do able but....4 range is safer and stable. Now if those are your Idle temps. Immediately drop your OC down.
Yes, i stepped down the multiplier to 47 i.e 4.7ghz.. now load temp is 60 - 65deg C and idle temp 25~30 degr C. V core is 1.4~1.42.. prime 95 torture test is running for 15 mins now with no issues yet.. keeping my fingers crossed
