Not bad - will be interesting to see how much more head room there is

damn man thats insane.

 

[roast]

F0ck.... thats pretty mental.
Can you push more Volts to get it higher, or is that max stable?

Sweet job man.

Thanks guys. Haven't push more volts yet, seeing how far they go around 1.475-1.50v cpu vtt and max 1.76v vdimm first. Still need the i7 980x to survive to complete my review hehe

How about 6-6-6-20 1T Windows max 32M Pi @DDR3-1850Mhz 6-6-6-20 1T, max 1M Pi @DDR3-1880Mhz 6-6-6-20 1T and validation @DDR3-1893Mhz 6-6-6-20 1T.

6GB Kingston 2000CAS8 KHX2000C8D3T1K3/6GX scaling tests, when I reduced the Uncore frequency multiplier from 24x to 23x - I reduced the Uncore frequency from 4128Mhz to 4071Mhz and thus managed to jump from DDR3-2064Mhz to DDR3-2124Mhz at the same voltages of 1.45v CPU VTT and 1.66v VDIMM all thanks to Core i7 980X's lower minimum Uncore to Memory ratio requirements!

@DDR3-2124Mhz 8-8-8-24 1T at 1.66v​

• 23x 177bclk = 4071Mhz cpu frequency
• 23x 177bclk = 4071Mhz Uncore frequency (cpuz reports it as NB frequency)
• 18x 177bclk = 3186Mhz QPI frequency
• 12x 177bclk = DDR3-2124Mhz memory frequency

Managing to use TurboV to push bclk incrementally until I reached DDR3-2230Mhz 8-8-8-24 1T at 1.45v CPU VTT and 1.66v VDIMM !

• 23x 186bclk = 4275Mhz cpu frequency

How about DDR3-2305Mhz 8-8-8-24 at 1.66v air cooled memory

6GB Kingston 2000CAS8 KHX2000C8D3T1K3/6GX
@DDR3-2184Mhz 8-8-8-24 1T at 1.66v​

Next step was to drop the Uncore multiplier one more step from 23x to 22x. You'd think this would by default allow higher memory clocks, but it didn't. The reason being on Asus P6T6 WS Revolution, Uncore frequency is tied to Round Trip Latency (RTL) A/B/C channels and auto adjusts to tighter RTL values as you lower the Uncore multiplier. For further reading on this check out the info about optimal Uncore to DRAM memory ratios for Core i7 980X.

So next step is to manually loosen RTL A/B/C channel values with Uncore multiplier dropped from 23x to 22x which allowed windows to boot in and pass single Super Pi 32M run @DDR3-2184Mhz 8-8-8-24 1T at same 1.45v CPU VTT and 1.66v VDIMM ! And ended up max screenshot captured clocks at DDR3-2305Mhz 8-8-8-24 1T at same voltages.

• 23x 182bclk = 4186Mhz cpu frequency
• 22x 182bclk = 4014Mhz Uncore frequency (cpuz reports it as NB frequency)
• 18x 182bclk = 3276Mhz QPI frequency
• 12x 182bclk = DDR3-2184Mhz memory frequency

• 18x 192bclk = 3457Mhz QPI frequency

Is 1.78V even safe? Nevermind, you wouldn't have cared anyway. Good timings though.

 

[SystemViper]

Now that is crazy, it's amazing what these new chips are rocking out, thnak for posting the results, it's very encouraging...

as always, very nicejob eva2000

[a_ump]

you should run a bandwidth test of somesort very nice

 

[DrPepper]

Yeah like everest ultimate or something.
