Munney: You should set your voltage to 1.20v manually and see if that is Intel Burn Test/Cinebench stable, if it's not move to 1.21 and see what happens and keep going till you're IBT/Cinebench stable.. This should reduce your temperature a lot if you can reduce the voltage needed. You may also like to play around with LLC and put it on medium (50%) or high (75%), this can reduce the vCore needed but will put more stress on the motherboard (which is okay to a certain extent).
I can't remember where the WHEA errors are located in the event viewer...
But so far at 4.6GHz with 2000MHz 10-10-10-28 with the Samsung RAM, anything over 2000 makes it unstable even at CAS11. Has anyone got any other advice for the Samsung RAM and overclocking with tertiary timings and such? I'm stuck at these settings now
That's the downside with this sticks, you don't get an xmp profile to base on for tweaking from there and some boards like my Gigabyte ud5h didn't play nice with them on auto.
I'd say take a look at someone else's mem tweakit screenshot and copy the timings, or use Sin0822 bios screenshots as a base. Normally you leave stuff on the value which auto puts it and tighten stuff individually till you get instability at a given clock rate.
There are a few things you need to know:
-These sticks favor this sort of timings 9-10-10-21-1t or even 9-9-10-21-1t. (higher clocks would net you 10-11-11-26 or 9-12-12-21-1t with more volts, or the most common 10-11-11-26-1t)
-They scale with voltage up to 1.7v more or less, but less is preferred. Sometimes voltage hinders your oc with these
-The Twl or twcl value should be a few notches away from the cas value, cause it determines the delay to write to cas again. You won't be able to boot with it in auto or you won't see performance increases with tighter cas if you don't tweak it. cl9 would need twcl 7, cl10 - twcl 8. (check techpowerup's Samsung ram ocing guide for more info on this)
-Depending on your cpu's ic and ram chips you may be able to get away with tighter tertiaries which boost your bandwidth significantly but also make the oc require more voltage (be it vdimm, vccsa/vccio or both)
-Have fun and test with memtest86+ at boot first to see if it passes a few rounds before going head on to Windows, and then test efficiency with maxxmem/aida/superpi32m or 8m
