Yes. At first I had the vCore at 1.38v and it was still a little shaky with the PLL set to 1.60v. Then I brought the vCore down to 1.36250 [which is actually the max voltage recommend by Intel], and raised the PLL to 1.70 from 1.64v and the VTT to 1.30 from 1.24v. I had the PC running at 3.6Ghz with the RAM at 1350Mhz for a good 5 hours until I stopped it to mess around and try to lower the voltages a little and to try and get the RAM to actually work at 1800Mhz like it was meant to.
