Core i7/X58 Overclocking Thread

[rge]

Ok guys, as promised. I tried booting into windows at 1.35 up until 1.69 until I was finally able to do so..

I went with the following setup to remove memory and CPU votages out of the equation.

CPU Multi 13x
Qpi Multi 36x
Uncore Multi 15x
Memory Multi 6x

Let me see what else

Turbo Off
HT off
Performance - Standard

any ideas?

One source said some bclk's would max out at 190's, some 200's other ~220. Mine has a very sharp cut off at 215.

With multi 15, QPI 36, UC 16x, mem 8x, Vcore 1.4, Qpi/Vtt 1.4, DRAM 1.66, HT on, my max bclk is 215, and can run spi there. 216 will not boot.

Then I can take it outside in 5C air, UC 14, mem 6x, Vtt 1.68, +/- DRAM 1.8+, and +/- red line all other volts, bclk will then go to 217 barely load windows then freeze. no higher regardless of settings. I walked both Vtt and DRAM up and down, (one poster said got high bclk with increasing dram volts +vtt both despite low mem setting, is why I walked DRAM up +/- vtt nothing worked.

your bclk seems to go from 205 to 211 like mine goes from 215 to 217. I think both are just near their limits.
