January 18, 201214 yr Prime95 can be overkill, but advise to use as Word Not Allowed mentions; I always test in occt and then prime for an hour...not the best I know, but at least I conserve energy! Stability was only a problem back on my old 920.Same here. I use occt for and hour and used Prime for an hour. Running at 1.37 volts at 4.8GHZ. Nearly the same as you...
January 18, 201214 yr Author Another question after 4,5 seems to be stable: How much improovement can I expect from these 300MHz more power? Best regards, Steffen Fight time: NGX 737-700: 37,0h; -800: 47,2h
January 18, 201214 yr Author Another question after 4,5 seems to be stable: How much of improvement can i expect from these additional 300 MHz. Will it be noticeable? Best regards, Steffen Fight time: NGX 737-700: 37,0h; -800: 47,2h
January 18, 201214 yr Author 300/4200 = 7.14%Like 30 to 32 FPSHmm, that´s not much but it could help in some situations! Best regards, Steffen Fight time: NGX 737-700: 37,0h; -800: 47,2h
January 18, 201214 yr Same here. I use occt for and hour and used Prime for an hour. Running at 1.37 volts at 4.8GHZ. Nearly the same as you...These 2700k's are not bad... :lol: Simon
January 18, 201214 yr Author These 2700k's are not bad...Definitely not but they´re somehow expensive. And I like my i5! :smile:Btw. I´ve tested it now in FSX and o far I can feel the more power in some situations. Also the temps rarely reached the 70-ies, NGX or not. :Big Grin: Best regards, Steffen Fight time: NGX 737-700: 37,0h; -800: 47,2h
January 18, 201214 yr 2700K doesn't pay off - for those 300€ more you get some 3fps-over-30fps (let's call it sure 10% in base case scenario). Call me a cynic with my 2600K, but the pricetag on the 2700K is ridiculous. Edited January 18, 201214 yr by Kosta
January 19, 201214 yr Just to tell you something: 45min on P95 doesn't mean it's stable OC. I tested once 3 hours, then played for couple of days, FSX and Starcraft 2, and then, out of the blue sky, in SC2, a blue screen, message that not enough Vcore.Couldn't it also be your vrm frequency?

Call me a cynic with my 2600K, but the pricetag on the 2700K is ridiculous.I wanted the 2700K purely for the overclocking potential. I didn't want to have to cross my fingers hoping I'd get a chip past stock.
January 19, 201214 yr Author I wanted the 2700K purely for the overclocking potential. I didn't want to have to cross my fingers hoping I'd get a chip past stock.Well, I've got my 2500k also way beyond its stock frequency and have only payed arround 180€.

January 19, 201214 yr 2500K = 200€ = OC usually 4.5-4.82700K = 330€ = OC usually 5.0So, we are talking 130€ for between 5-10% performance boost.
January 19, 201214 yr Think the 2500k is cheaper than the 2600k and 2700k's due not having the useless HT, but has less cache by 2 mb; seems that larger cache does help in many applications including games. Nick N has said the 2mb extra cache would be of use for FSX, but who knows. I would pay for the extra cache. 200-300 euros for processor is reasonable. Anything that may help a smoother flight is key to me besides 6 cores :LMAO: On the FSXMark 11 spreadsheet they seem to do better than the 2500's at similar clockspeeds, but there are memory and GPU differences that I did not look that closely at...

January 19, 201214 yr There's a Sandy Bridge Stable OC thread at oveclock.netNot too many 2700K samples, but apparently 2700K/2600K/2500K overclock just the same
