WOOT after working on my overclock for a while i finally hit 4.0 stable on air cooling.
I can post pictures of my setup when i get home
who else has gotten this proc to 4.0 on air?

I tested it stable with 6h Prime95, 2h OCCT, 14h Memtest86+.


ooo,nice1..
but,70,71c is still within safe temp range for 24/7 proc, right???

got my e7200 and try OC it, but currently got to 2.66Ghz..huhu,mehhh

but, more weird thing is, CPUz keep showing my cpu multiplier change between 9.5x and 6x..WTH is going on??
mybe cause by my old mobo???mobo gigabyte945GCMX-s2..
any idea y???

My memory is also overclocked from 800 MHz DDR2 to 889 MHz DDR2. I had to go all the way to 2.10V for the memory and 1.32V for my northbridge,

I recommend you test separately for memory (Memtest86), cpu (Prime95 small FFT) and overall (Prime95 blend). This way, you can isolate the problem and add voltage where needed.

Hope this helps!

ooo..will try it now..but i've been testing..set bios vcore up to 1.4026v..finally got stable in 10min OCCTv3.0.1 test..cpuz state vcore 1.376v..ddr oso oc to 889mhz @ 2.1v..is tht vcore save for 24/7 ??? i read an article said vcore 1.4v is still within safe range...oso, temp 41C idle,63C load

ooo..mine default vcore 1.225v..seems quite high..
hve tweak my mobo accordng to ur stting except cpu freq at 369..only wnt OC to 3.5Ghz cause mine hsf still an avarge brand..idle 41C,load 63C
btw,vcore need set up to 1.4v to get stable 10min large data set OCCT test..
didnt run prime95 yet but i think usually past OCCT = past prime95
1.350v = failed
1.375v = failed
didnt try btween 1.375-1.4v..
cpuz vcore shown 1.344v..
is bios vcore 1.4v safe for 24/7 system???

mine is m0 stepping..
nah,quite satisfied w/ what i got now..apparently, able to max out every game i played, except for warhead, of course..at 1400x900 native res,not really asking for demanding OC,3.5Ghz is enough..i think,maybe my 88GT bottleneck the rig now..
1nfinity said running vcore 1.4v for 24/7 sytem is still safe, so, no problem then..
thx for advices..

oo..i notice OCCT stated their cpu:linpack test same as IBT..prime need long time to determine system stability..so, use OCCT for quick stable OC test n prime for further stability test then..
btw,about Load Line Calibration option, does every mobo bios hve that opt??
i seems cant find that opt anywhere in my bios..

OCCT is very helpful to quickly determine stability
Memtest86+ is very good to isolate memory problems
Prime95 small FFT will help you identify CPU related errors
Prime95 blend, 6 to 12h will help you determine overall system stability

Intelburn, I don't use it. Instead, OCCT 3.0 has a test called Linpack which is the same test as INtelBurn. I use this Linpack test for a few minutes only to see how my cooling system is working. Running it 5 minutes is enough!

I consider my system stable if I can run 6h of Prime95 blend + 2h of OCCT + PCMark05 benchmark + at least one day of regular use
ooo..
..nice guideline

waaa

does modding mobo complicate ??
