AeroZ Posted October 13, 2011 Posted October 13, 2011 (edited) BIOS settings: AI Overclock Tuner = XMP By All Cores = 45 Internal PLL Overvoltage = Disabled LLC = Ultra High VRM Frequency = 350 Phase Control change to = Extreme Duty Control change to = T. Probe CPU Spread Spectrum = Disabled C states are all enabled Latest stable: CPU Core 1.312v - 1.336v (1.320v in BIOS) CPU PLL 1.500v VCCIO 1.000v VCCSA 0.900v DIMM 1.500v PCH 1.05v (default) Temps in 50 run LinX is 72-78C. 65-69C in Prime95. Is it safe? I'm still curious about VCCSA, VCCIO, PLL and PCH voltages. Try to lower them more? Increase something? Any use getting PLL even lower?

My_Inner_Fred Posted October 13, 2011 Posted October 13, 2011 PLL Overvoltage should be enabled while overclocking... And the voltage settings should be fine on auto no need to up the voltage manually. Share this post Link to post Share on other sites More sharing options...
AeroZ Posted October 13, 2011 Posted October 13, 2011 (edited) PLL Overvoltage should be enabled while overclocking... And the voltage settings should be fine on auto no need to up the voltage manually. They aren't upped. I basically froze the default settings. Also what's the difference between PLL auto and enabled? I've been googling and found that PLL needs to be enabled to unlock higher multipliers? I'm not sure. Lots of people talk different story. Also when idle the vcore is 1.344v and sometimes jumps to 1.352v. When I run prime95 then vcore jumps between 1.336-1.344v. Lower voltage under load than idle?

Brutality Posted October 15, 2011 Posted October 15, 2011 (edited) Use LinX to stress/stability test your SB processor. Prime95 does not stress these chips enough to ensure stability. Link for newest LinX But watch your termps.. LinX can make some serious heat compared to p95 Edited October 15, 2011 by Brutality Share this post Link to post Share on other sites More sharing options...

Link for newest LinX But watch your termps.. LinX can make some serious heat compared to p95 I lowered my overclock to 4.3ghz. Ran prime95 during the night and was stable. Did linx in the morning and had to add 0.010v to get stable. Right now my idle vcore is 1.288v and under load it's about 1.240v. Internal PLL overvoltage=auto LLC=high VRM freq=auto Phase control=standard Duty control=t. prob vcore manual= 1.280 other voltages are on auto Edited October 15, 2011 by AeroZ Share this post Link to post Share on other sites More sharing options...

AeroZ Posted October 15, 2011 Posted October 15, 2011 (edited) Got stable with 4.4. Any other tweaks to do? Another run on 1.270v gave me bsod so upped vcore to 1.275v and stable again. Edited October 15, 2011 by AeroZ Share this post Link to post Share on other sites More sharing options...

I might even get PLL lower but is it wise to do so? How about other voltages? With these settings I pass Linx 50 times test.

HarryTaco Posted October 15, 2011 Posted October 15, 2011 If you are not producing any inordinate amounts of heat they why worry about the voltage? You are well within OC voltage specs on the chip. If you need to increase marginally to get 4.6 stable on your prim95 or that new LinX then so be it. Each chip has a little different requirements. Good Luck.

Good Luck. I'm just trying to tweak my current OC as much as I can. If I want to reach 4.5ghz then i'd have to increase vcore another 0.050v for start. That makes about 1.330-1.340v to get it stable. At that speed I'd probably get 75C or a bit more with LinX. Tried 4.5ghz too. vcore 1.312v-1.336v (1.320v in BIOS) other voltages are the same as for 4.4ghz. Temps in 50 run LinX is 72-78C. 65-69C in Prime95. Is it safe? I'm still curious about VCCSA, VCCIO, PLL and PCH voltages. Try to lower them more? Increase something?
