AW: [Review] Hat der uralt Sockel 1366 eine Chance gegen Haswell? Westmere als CPU Geheimtipp..
Aus aktuellem Anlass paste ich hier noch mal meinen "how to" Beitrag von Seite 3xx? rein.

Welcome to this Forum! It is really a huge threat running longer than one year!
Sorry for typos and weird words as I am typing this with my Smartphone.
The e5620 is 32nm what is good. Not too good is the Multi of only 18. (18x133=2,4Ghz).
To overclock properly, you need to find out the max BLCK. To do this, follow this:
PS: Before you start, set manu RAM settings and set umcore to double freq of your RAM. Disable any spread spectrum setting to increase stabiliy. Turn on load line calibration: this avoids that VCore drops with CPU Load. Many recommend to turn it off AS it Harms the CPU - but this is not the case AS long you use low VCore (below 1,275V).
#1 max out the BLCK
Firstly set the VCore voltage to a fix standard setting (1,25) and qpi Voltage to 1,25V AS you need this for running BLCK above Intel specs, lower the Multi to 12 and Start raising the blck ( what is the same AS the FSB in former CPU Generations):
12x160=1,92Ghz
12x165=1,98Ghz
12x170=2,04Ghz
12x175=2,10Ghz
12x180=2,16Ghz
12x185=2,22Ghz
12x190=2,28Ghz
...
PS: keep in mind to keep your RAM freq weithin specs while increasing BLCK. If you get above specs, +0,07 extra V is no Problem (for instance up to 1,57v instead of 1,50V)
Between each raise, run Cinebench R15 three times (Multi core bench). Watch the temps while doing that - more than 70C I would not recommend as you might get too high temps with prime later.
If any run of CB15 crashes or Computer reboot with blue screen. The step before is probably the last stabile one (to make sure, run prime for 3 hours with target BLCK). If the temps are quite low, you could think of raising the voltage of the qpi Voltage, VCore or IOH Voltage one step to See if you get this BLCK step stable AS well possibly.
#max out CPU freq
Assuming, your final stable BLCK is 185, you can now Start raising the Multi step by step:
13x185=2,41Ghz
14x185=2,59Ghz
15x185=2,78Ghz
16x185=2,96Ghz
17x185=3,15Ghz
18x185=3,33Ghz
Run CB 15 three times Before you move on to next multi. AS BLCK keeps fix, increasing stabily can only be reached by more VCore. AS heat increases heavily with every extra voltage you give your CPU, be carefull and keep your eyes on the temps. More than 75c in prime I think is not acceptable for 24/7 usage.
Comment: deactivating Hyperthreating, or any energy saving Mechanismus increases overclock stabiliy, but honestly, I would keep it turned on to make your PC cooler, more quiet and longtime reliable.
Happy to help
