Started doing some serious clocking in march earlier this year. Practically have been using water from day one of my overclocking experience
.
Anyway I thought I'd see if anyone has some tips for how I might get slightly further with this chip as far as 24/7 stability ( I really am but a nub still at this stuff) goes. Weirdly the more I thrash it at higher volts when benching the better it seems to get or maybe I'm getting better at 24/7 stability clocking {who knows}. 72 degrees was reached with what I would currently regard as toasty temps for my room so there's still headroom if the chip is capable of going further and luckilly for this CPU it shares 2 RX360s with a mobo chipset and one HD5870 so it's pretty lucky.

Only a 3hr shot but it's pretty stable. Uping Bclk (I've tried up to 168) gets errors within a few minutes on Prime but doesn't cause the rig to crash. Bclk wall for this chip is 180mhz. Might have a rig shot lieing around to make some of the modders on this forum freak out at my frankensteinary
Current volts ~ set in bios
MCH Strap - 1867Mhz (next up is 2133mhz0
PCI-E - 110 Mhz (playing this more so for when I go to do some 920 clocking in the near future. Worth noting that until I played with this frequency the best I'd achieved was roughly 4.2Ghz)
CPU Vcore - 1.45
CPU VTT - 1.325-1.35 (not quite sure what EVGA uses for there E760 as stock voltage for this. Seen testers refer to it as 1.17 and 1.2)
CPU PLL - 1.86
IOH PLL - 1.86
QPI PLL - 1.35
Vdimm - 1.65
Vref - +0mV
IOH Vcore - 1.25 (have to check as it might be higher or lower)
IOH/ICH I/O - 1.6
ICH Vcore - 1.2
VTT/PWM frequencies set at top frequency atm. They are normally set at the top frequencies or the lowest depending on what I'm doing (I think this is the main thing I'll look at tweaking for higher stability as my chipset/PWNs are WC/d). Last two I set at auto though QPI compensation might also be worth a tweak. It's probably only got maybe 1 to 2 more benching sessions in the near future and then it's retiring to a perma 24/7 chip.
Guts, Patience and Glory ? ? ?
My benching session results so far. I'll try get the validation pictures for th other 2 though both Wprime shots are availible on HWBot (may be slightly different as I'm going be memory for this).
Best Wprime 32M ~ 4.773 Ghz - 5.366s
Best SuperPi 32M ~ 4.975 Ghz - 7m 26.972s ( I wanna try and beat the worst cascade score of 7 min 25 secs which would be awesome
)
Best Wprime 1024M ~ 4.677 Ghz - 166.66s (it's a seriously hot chip though and heat is definitely my limiting factor on this bench. I reckon I can improve on this by working my way up slower with the volts rather then shooting straight for 1.65 in the bios or 1.56 @ load)
Best Boot Frequency ~ 5.003 Ghz
(was a pretty cold night when I did these benches, might of even been in the low -ves in my room
)
