Pretty stoked to be working towards my certification into the club!
I'm looking to do a modest overclock, and I'm running into challenges and am almost there.
Currently set going for 4600MHz.
First I used the mobo preset OC of 4600MHz to see how the system would react.
Results were: (Click to show)
Vcore @load: 1.368/1.371, VID 1.406
with 19 hrs on blend.
So wanted to first lower the voltages.
So now with manual I'm at: (Click to show)
Vcore fixed = 1.352V
VID = 1.3861V
Max temps 65/68/67/66
with 2 hrs blend and 20 mins custom 1792 / 1344 @ 90% Ram
However now trying to tweak with Vcore offset.
My BIOS Settings: (Click to show)
Internal PLL Overvoltage = Disabled
Intel SpeedStep = Enabled
Turbo Boost Power Limit = Manual
Short Duration = 250
Long Duration = 250
Additional Turbo Voltage = Auto
CCL = 250
BCLK = 100.0I
Spread Spectrum = Disabled
Power Saving Mode = Disabled
LLC = Level 2 (Ultra or 75% equivalent)
DRAM Voltage = 1.5V
PCH Voltage = Auto (1.059)
CPU PLL voltage = 1.709
VTT = Auto (1.09)
VCCSA = Auto (0.925)
So doing the calculation, my Vcore offset should be -0.033, so used -0.030 per options available
My idle VID was low, like 0.987, so my Vcore at idle would be 0.957-0.962 or something to that affect. I understand if it's lower than 1.000V, that it can cause randome BSoDs.
So I tried changing my LLC to level 3 (50%), with no luck in boosting the VID, and it rebooted in a few seconds once in windows.
Any recommendations on what to tweak to make it stable? I was thinking of reactivating Spread Spectrum, but when I had it enabled before, it brought down my BCLK to 99.8, so it affected my core speed a bit.
I even set my VTT to manual @ stock, and no difference.
Thanks much everyone! Edited by ped5 - 2/22/12 at 1:44pm
