3920xm...what voltages and clocks are you using?

i have to up the voltage by 3-8mv to maintain 4.3 Ghz but i have no idea how much i should throw in to hit 4.5ghz-5ghz safely. A little advice and info would be much appreciated. I am gunning for 5Ghz pretty much for single thread purposes like for old games (RCT3, Rome Total war, and many others and for Opera browser -_-)

I am just rocking 4 GHz across the board for now until i figure out a good place to start. I think in my m17x R4 i can get 55-60 w TDP.....maybe 65 if i am lucky....cold room and such (55 TDP gets me ~90C 60 TDP was only marginally more) The room currently is warm so it could easily drop bit. Also for single thread i shouldn't press 55-60 w TDP for 5 Ghz from what i can see so I should be good. Even if i have to work a little magic that isn't a big deal because i'll be at desk for gaming so i can just turn on cooler.

 

Have you repasted the CPU and made sure you are using the thinnest thermal pads you can get away with?

 

Thermal pads for CPU?

 

using the last of my heat-spring...i also tried it with a little ICD to see if a hybrid set up worked...it seems comparable. though ICD was a bad choice...figured it would be.

m17x R4 just has a crappy fan and heatsink...the fan is like half the size of the GPU one. The m18x has a much larger fan :/ and better heatsink

 

Yes that make contact with the VRMs.

 

Voltage regulation module? Isn't that on the
Mother board

 

- Start here M17x Retention Mod
- Flash stock A11 BIOS -> FPT A11 Unlocked BIOS/method 2 [M17x R4] - 'unlocked' BIOS versions
- Advanced CPU Control -> Turbo PWR Limit MSR Lock -> Disabled
- Override Turbo Settings Enabled
- Extreme
- Long Duration Power limit 80
- Long Duration Time Window 28
- Short Duration Power Limit Disabled, try both (enabled) Short Duration Power Limit 80
- Level overclocking disabled.
- Flex (3) - 7 for 4.3GHz.
- Match settings w/ ThrottleStop 6.00

 

What?! I have no thermal pads on my i7 4900MQ? Nor on its heatsink?

 

..........

 

Again my machine did not ship with thermal pads there.

Neither did my previous r4.

 

Newer AW seem to not have thermal pads on those inductors. Since VRM are integrated onto the CPU on these Haswell machines, perhaps the Dell engineers think that the inductor won't get too hot. They don't get that hot anyway. If you want to put pads there, it will have to be really thin 0.5mm pad. Thicker pads will prevent proper contact with the CPU die and causes increased CPU temps.

 

so 3-7 flex voltage for 4.3 GHz and above...what about 4.5 and 5GHz? I should be fine with stock BIOS for what i want to do...i really dont want to take the time.

 

Perfect, by change the pch chipset isn't located there is it on brewer models? Because that part of the machine does get hot. But otherwise my temps are fine.

 

have anyone of you have to increase amps for overclocking? i forgot to adjust amps so maybe that is why i was crashing at 4.3/4.4GHz

 

Amps needs to be upped for any amount of overclocking and even normal usage to sustain high turbo clocks. Or the machine will be unstable. But not necessarily crash.
