My DRAM Frequency is stock so it's BCLKx8 = 800MHz with a FSB:DRAM of 1:6.
I know I've got a very solid motherboard for tweaking things, so how would you suggest that a total nooblet to OC RAM like me goes about to stabilizing this in a way that's going to be meaningful to my performance?
Well overclocking your RAM isn't really going to give you any noticeable performance increase unless you do benching. Have a little read in my other thread: Overclocking & Choosing RAM for Sandybridge H67/P67/Z68.

No, if you find that the hard FFT's work well for you and they don't show signs of inconsistancy then yeah, do the hard fft's, if they do then just use the default custom blend with 90% of available RAM.

Good luck bud, hopefully you can finally join the club

I will try to set C3 and C6 to auto.
The funny thing is, when I try to run memtest 86+ it instantly reboots my PC, it doesnt even load the interface from my boot disc.
C3 and C6 on auto while using manual voltage should do the trick, however I would recommend using offset voltage and c3 and c6 disabled due to the sata throughput affect. I do believe I have mentioned this in that thread that shad0wfax linked you to.

Settings are as followed:
- XMP profile
- Pll Overvoltage is enabled
- EPU disabled
- LLC set @ Ultra High
- Current Capability @ 130
- VRM set at @ 350
- Speedsted/C1E are enabled
- C3/C6 are disabled
- Duty/Phase Control set @ extreme
- All the rest on Auto
First, I'd like to know if the settings I use for Prime 95 are appropriate for my build. I heard using a bit too much memory could cause aberrations.
Secondly, I heard there are much more reliable ways to test stability than Prime. Could someone give me some input on the subject?
Lastly, I like to hear any tips and settings that could help me reduce V-Core consumption.
Using custom blend and 1344 and 1792 can help for a quick test, however, with any quick test there can be inconsistencies, therefore I don't recommend those ffts, however if they work for you then great if not then a custom blend with 90% of available RAM should do the trick. Just a note, using those FFT's you can either use 1600mb RAM (default) or higher, which in turn makes it even more difficult to pass. Unfortunately there are debates as to what is the best stability tester for sandybridge, myself and other's have found that prime blend with 90% of ram is the best one, it stresses the cpu and RAM together with the IMC.
How long have you run prime with 1.392/1.40v? That is pretty amazing voltage for that overclock!!!
