[Alienware 17R4 / 15R3] - Disassembly + Repaste Guide + Results

Never tried it. I use my own crappy app to find out best undervolts and stress test. Most of the time with AVX workloads even I have 1-2deg core difference on actual cores and 10C on virtual cores.

 

These are the cores, although its numbered from 0-3.
Check the numbers (in your case 0 is 1) and see where the problem is.

 

Thanks, I thought it was in this order but you confirmed it. Must be the GPU thermals pads next to it then pushing that side slightly up. All core temps are good and close to eachother except the second core (core labeled 1 in the pic).

Sucks that the thermalpads arent very compressible on the heatsink. Gonna replace them with Gelid pads.

 

repasted my R5 with i9 8950HK and GTX1080 yesterday with LM and new pads. Thanks @iunlock for this awesome guide

cinebench 4.5ghz


Far Cry 5 15min warm up @4.3ghz then 15min 4.5ghz test

 

Hmm thats good to see actually.....gives me faith in this design. So with the right paste and thermal pads this machine can do exceptionally well. Even though a lot of people have shown good results, some people claim it is impossible.

 

4.5 ghz @ 1.1v VID ? At full load?

I am calling Shenanigans on that one.

 

that is with undervolt

 

Hi all,

I previously did re-paste and re-pad, but because my heatsink is badly fit, 1.5mm or more thermal pads are required in many places so even though I use all Fujipoly 17 W/mK pad (a real pain in my wallet) it is still not efficient enough. Half a year and they dried out because of extreme temp (it is almost always 30+C in my country).

Now I am thinking of SOLDERING COPPER PAD to any places where a thermal pad of 1mm or above are required (1mm copper pad for 1.5mm gaps, for example). After this process using ONLY 0.5mm THERMAL PADs is sufficient to fill those gaps.

I did have a research through different kinds of solder pastes and decided that Sn63Pb37 is the paste to go. It has melting point of 183C and is one of the most thermal conductivity.

The only thing that worries me is WHETHER THIS SOLDER PASTE CAN STICK TO THE "GREY" ALLOY OF THE ALIENWARE'S HEATSINK OR NOT.

So, could you please give me advice on this?
Thanks so much.

Edit: Sorry but I will mention you here @Papusan @iunlock

 

Most likely tricksing with vcore. Probably same nasty as MSI. See running +55mv higher voltage but 6% lower power consumption for equal clocks. You find the same for the 2017 Aw models as well.

 

You mean the AW Bios is tricksing? Because i just set my undervolt with XTU. With this messed up Bios i have no chance to undervolt per Bios...

With LM Repaste and good pads the R5 with i9 8950hk and GTX1080 is a great rig... nur i know it should work this way out of the box.

Edit:

A few results

Occt 4.3ghz 30min


Occt 4.5ghz



Here i used TS to undervolt... but now it showes higher voltage... Power comsumption was around 85-90w... Maybe xtu was tricksing around?
