It even works on my costa higher vcore though. Definately better when i had the malay running on those settings , RIP aaskull.gif

That was a good chip redface.gif

You think yours is dreadful Roch.... heres mine.

125x36
125 strap
1.376v at idle
1.360v full load
Ram clocked at 1666.6mhz (from 1600) @ 1.51v
Idle temps 32-35c

Im using manual voltage not offset (was complicated to setup). Also have Turbo and Speed step turned off as they do nothing when using manual voltage.

For the life of me when I approach 1.360v (in bios) the system will BSOD under stress test. I like having the bclk at 125 which keeps the QPI link (related FSB) up and I get about 5% better bench marks.

Should I downclock to something like 100x43 and get the voltage down?

So because Im using such a high BCLK that's why I cant get the voltage to go down at idle? When using the higher BCLK the QPI Link runs at 5000mhz, I get about 5-8% better benchmarks this way.
Are you using offset mode to control voltage?
If I'm not mistaken, Speedstep requires you to use voltage offset, it won't work if you manually set a voltage value. Unfortunately, the voltage offset in turn won't work if you use any BCLK strap other than 100.

Have you tried playing with other voltages? I had to set VCCSA to 1.1 when for 36*125, any lower would result in errors.

That is not true. Offset voltage worked really well with STRAP other than 100. See mine here:-
http://www.overclock.net/t/1221208/i7-3820-overclock/1100#post_17815713

Speedstep will worked well too either manual or offset voltage. The CPU frequency will throttle down when idle. For the voltage when using STRAP, the voltage only go down a little when idle.

Unless your ambient is high, the temps seems slightly high though with H80. I got similar temp with H100 & ambient 31 - 34C.

Latest 5200Mhz Prime95. Ambient 24C...Made "some" smile.gif further changes in the system and could take Vcore from 1.480 down to 1.464. Fluctuates between 1.456 and 1.464 during testing.

I can actually use 5200 at 1.448v for games and everything else, runs stable, no crashes at all thumb.gif ....

For P95 I took it a bit up.

idk how....i have a malay chip and cant do 5ghz on 1.5volts on an H100.....home theater can you give me all your settings?

ambient is 21-22c but I have 4 Hard drives and 3 SSd's plus 8 sticks of ram, and my psu in the bottom of my case.
idle temp right now is sitting at 31-35c across all cores
