P150SM GTX 780m unboxing photo's of the build.

:thumbsup:

yep..... I think maybe the multiplier is limited to +2 although despite upping my TDP to 60w I still can't hold 3.4Ghz (3.2 is stock) on prime 95..... I actually have to reduce the core voltage by around 130mv as stated previously. This gets it going at 3.4Ghz on all 4 cores but it's not enough for it to hit 3.6Ghz on single threads so I've reduced that to 3.5 and it's stable for now....

My tweaks with the 4700MQ are as follows

1-core multiplier x35
2-core multiplier x35
3-core multiplier x34
4-core multiplier x34

Dynamic CPU voltage offset -125mv

This pushes my CPU package down to/under 45w under load (8 thread, prime 95, max heat & power) & it will hold 3.4Ghz

I'm hoping the new copper CPU cooler from the P170SM will give me an edge but I've been told its almost a month away sadly. I think the issue might be heat related..... I like solving heat related problems

 

That or the TDP is actually locked and its not really changing.

 

Yeah that was my fear, I have seen numbers to suggest otherwise but I don't know, it's early days, maybe that all copper heatsink will make a difference. I'll remove the bottom cover and see what I can do to improve cooling and re-run a few test's when I've got time to play again - for now it seems happy enough at -120mv without the 3.6ghz single core clock - which I don't value much tbh.

 

i wouldnt have expected the cpu to get unstable so early on at 3.6ghz already. thats not much of an ocability... would probably still be necessary to crossflash the p170sm bios in order to further unlock xtu (more multipliers? higher tdp values? or just ask prema to hardcode higher tdp into the bios )

Having not owned an overclockable sandy or ivy I don't know what to expect, The 3.6ghz seems fine, it is just the -130mv it doesn't appriciate (is this not much of a reduction compared to sandy/ivy?) the core voltage was 0.945v (stock is 1.077v) does anyone know the stock voltage of the 3610qm?

I'm hoping it will run fine at the higher voltages once I get this copper cooler fitted and the bios/platform is a bit more mature.

 

Ivy would typically reach 4-4.2ghz on stock voltage.

However running an undervolt of 0.1V is actually quite large.

 

Yeah I think it was pretty solid at 3.4-3.6Ghz with stock voltage - I was really pushing for all 4 cores to run 3.4Ghz continuously without using throttle stop or anything.

That is how I arrived at the -0.13V undervolt, as I assumed it was lowering it's turbo because it was either out of the allowed power envelope or out of the thermal window - both I figured would be improved with lower voltage. This proved fine under prime 95 load, but it just couldn't handle the under volt at idle - presumably at idle it down clocks and under volts even further.... leading to further thoughts in my mind.....a few things I haven't done properly to be honest, I rushed in to it a bit to eagerly and forgot the basic foundations of OCing...... I didn't disable all the power saving features in bios and obviously I didn't use throttle stop, I should have probably used some more stable RAM (I've got a mismatched crap selection dodgy ram)

I'm sure it will be better in time and with a better bios maybe

 

Simply put -0.13V is a massive undervolt and you are likely running the chip at its max frequency at that voltage.

That setting is applied to your idle voltage as well as your turbo voltage.

 

yeah I've backed that off and still hold 3.4Ghz in games no trouble at all.

I'm really getting p!ssed off with these fans, they just stick at 100% randomly.

CPU is at 63°C under load, fans are near silent and the total CPU package usage is around the 20w mark in game.... and BANG 100% CPU fan speed - I can't hear myself think, they fix one fan, and break the other! I'm so pissed right now!! this is the 4th time in an hour I've had to completely stop gaming and turn off my machine to shut the fking thing up!

 

rebooted the 5th time - this time it came back on at 100%!!!!!! I had to reboot again

just out of interest during normal gaming CPU fan is about 2600rpm (4200max) and the GPU is around 2700rpm (3500max)

fan speed at idle is
2400rpm on the CPU (so it's hardly moving under load, until it explodes to 4000rpm and sticks there.......)
1925rpm on the GPU


It would be nice to get a bigger fan on the CPU (same as the one on the GPU) my copper cooler and spare GTX 780m coolers are arriving on the 4th or on the 17th of July

and I expect the 8970m versions to arrive in the UK on one or the other date too if anyone is waiting, but this just me speculating, if not on those dates then your looking the very last week in July which doesn't fit the other speculation.

Edit 7th & 8th time....... and I'm done for the night....... what a sh!tty annoying problem

Stressing lol

 

6th time tonight........ no reason at all, bam 100% from 2600 to 4200rpm mid match.......... lovely, exit, shut down, restart....... marvelous

its actually both fans, but the CPU is roaring so loud I couldn't even hear the GPU fan

 

I think I'm having this problem right now. I just finished playing Metro Last Light, and my fans are at 100% (I've stopped 5min ago, GPU off and CPU @40c...).

On demanding games, what kind of temperature do you have ? Do I have to worry with my 92 on Metro Last Light ?

Edit : OK, no, it just takes ages to come back to normal ><

 

Looks like the EC bios needs tweaking.

 

If your on bios 01 then the GPU fans sticks when the GPU turns off, try to give it a small amount of time to chill just before you quit, this will get fixed but for now it's not to bad.

My GPU fans reduce in speed almost instantly as soon as the load eases off

92 peak should be ok, but the fan profile should target 80 and it should be easily achievable (my ambient is around 18-22 typically).

If you get the new hwinfo beta Martin has added the SM's EC sensor so you can read the fan speeds and average them roughly, compare them to mine.

From what I gather there are a few different bios out there (have a look at the online reviews) some people have 01, some 02 or 03 now maybe (not sure) but I'd stick with 01 till 04 comes out if I were you - it's probably the lesser of 2 evils...

I've said this before, but I'm still not sure how your supposed to get or check what the latest bios is from Clevo, I think maybe contact your supplier, but as I said at a guess skip bios 03/EC04.......

 

Have you seen the new Eurocom X3 P157SM review on notebookcheck? Not sure what BIOS that's using, but they recorded a high of a whopping 57.4 dB(A).

That's mental - About 10dB less than a freaking vacuum cleaner.

Would love to buy one of these things, but spending $2000 on a "relaxation machine" which would keep housemates awake is a hard sell =\

 

Yeah they were running the 4930xm with the 780m, these are the most powerful and no doubt hot components ever to be made for a laptop! And they ran synthetic benchmarks for over an hour!

Also worth considering that dB is a log scale so the sound pressure doubles every 3db, I'll lay down the exact maths in w/m2 once I've got scientific calc to hand and we'll see how many times louder 63dba is over 53dba.

That is just an EPIC configuration, also worth noting they used the aluminium version of the CPU cooler (that's a bit silly) and also I can't confirm (because I can't compare) but the exhaust vents of the P1*7SM range have a metal grill over them, and to me this looks restrictive, especially when compared to the P1*0SM which is nice and open, you can see right in to the cooler fins!

 

Yes I often wonder whether it's the CPU fans that are causing a good portion of the trouble.

The problem is, all p15Xsm models use aluminium don't they? I'm thinking of firing my local builder (metabox.com.au) an email and seeing whether they could throw a copper system in there from the p17X models. Though I doubt they will.

And I saw you mention that about the grills on another thread. It's really hard to say without a direct comparison between the two - still hoping someone will.


I really want to fire off my order for a p15Xsm with either 8970m or 780m - but for every person who says the noise emissions are fine, there's someone saying these things are screamers.

 

I was playing Planetside 2 last night and the temps hit 92degrees. Fans weren't at 100%, so a quick FN+1 brought the temps down to 88degrees, roughly.

Fans at 100% is quite loud, but no louder than my Sony S15 Vaio that I had previously. That only had one vent!

Thinking about buying a copper cooler myself. Might bring temps down slightly.

I'm still worried about the slight screen tearing I'm getting whilst gaming/benching.

 

Hmm. That's disappointing - Planetside 2 is one of the main games I want to play.

I take it you have IC Diamond on your CPU/GPU?

 

Yes. The more I read about the 780m in these machines, the temperatures don't seem to be great, many are going over 90degrees just while gaming. That's not something I'm overly comfortable with really.

It has been quite warm here in the UK over the past 48 hours, ambient temps of roughly 20 degrees. I also don't play with a laptop cooler, either. I tend to either play on the sofa or in bed. Putting the laptop on a flat surface though, so it can breathe properly.

Edit: I was playing FIFA13 last night too and temps never went over 55degrees, but thats not really a graphic intensive game

 

Mine is the same mate, I don't know where people are getting these bull sh!t figures from!

I'm seeing 55-60°C CPU and 80°C - 85°C on GPU at the very worst (at 79°C the GPU fan reduces speed, so 80 is the ideal target that the fan speed is aiming for, same on the CPU, the fan only starts at 55°)

my CPU, GPU, RAM & VRAM are all overclocked, and none throttle, temperatures are under control. This fan speed sticking to 100% is a problem, they need to fix it! the lack of a low inaudible fan speed is annoying they really need to add one!


So here's the deal breaker, the MSI game benchmarks from Notebookchecks 780m page, are all lower than the Clevo scores and clearly highlight an issue,

Notebookcheck quote

"We were surprised that the GT70 scored a bit lower than the One K56-3N2 and Schenker XMG P703 GTX 780M contenders in CPU-heavy games, such as F1 2012, Dirt: Showdown, Call of Duty: Black Ops 2, Assassin's Creed III and Skyrim. Both the processor's and graphic's Turbo were inconspicuous in "normal" 3D operation. Perhaps the Clevo laptops have a superior driver although the version number actually indicates the opposite (ForceWare 311.27 rather than 311.48)."

This is just b0ll0cks, the reason it is so CRAP and SLOW is that it cannot handle the heat and power, yes it's quiter, but it's running at 2/3rd of the speed and the manufacturers limit for the silicone - they are a sinking ship, frantically dumping Mhz trying to stay afloat!

here are some of the numbers, but MSI is BOTTOM in every test even with the same CPU

Assassin Creed in ultra

MSI = 36.5fps
Clevo 42.6fps

Call of duty black ops

MSI = 85fps
Clevo 95fps

Bioshock Infinate
MSI = 43.7fps
Clevo 46.6fps

F1 2012

MSI = 79fps
Clevo 100fps



Fair enough, the noise and heat are high in general (this is the most powerfull MXM card ever made), but compared to other brands, the noise might be higher, but the temperatures are lower, and the performance is measurably higher or equal in every gaming benchmark done

 

I might try a 8970m. I have a feeling the new heatsink will help it considerably considering its just a very slightly improved 7970m.

 

8970m seems very poor compared to the 780m, though.

Couple of early benches here: http://forum.notebookreview.com/gaming-software-graphics-cards/723142-8970m-benchmarks.html

 

you guys with the heat issues, have you tried propping the back of your laptop with a bottlcap or rubber stop?
that was also an issue with the hm series, where there just wasnt enough clearance underneath for the fan to work effectively. ive personally registered 6-10c lower temps on my machine (an hm) and im quite sure it will help with he sm's too

 

HM series? Please. I've been doing the same with my laptop for a while ... )
It actually depends on the surface, it doesn't make much of a difference on a flat, hard surface. But if you have a table cloth for instance, it's a must.

 

well ive been doing it since i got my 8690 but the difference is more pronounced in the hm.
in my case it makes a difference no matter what surface.

 

I use two erasers, and it works a bit (-5c).

 

I use my P150SM in bed and on my lap, mostly.

Might be ordering a laptop cooler. Will give it another week and see how the temps go.

 

Any update on the new heatsink yet, Calibre?

 

I agree with this 100%. I've seen marked improvements on my NP8662, NP8170, NP9150, W110ER by propping the back up. I don't know why Sager doesn't offer a flippable kickstand on both sides where the rubber feet are, or just larger bumpers altogether. It really only needs a 1/2".

 

I fully agree.

 

In all honesty, I've been a bit to busy between other projects, but it will be coming soon enough - I could probably pop out a "cover" type block similar to the W110 if anyone is interested just as a nice little add-on. It's not going to work miracles for the temperatures, but it is certainly one step in the right direction and it's another angle covered :thumbsup:

 

Make me first on the list for one of those Calibre.

 

I will do if I make one, I'm looking towards other things now but I will revisit this method once I ironed out some of the cutting methods and made some proper tooling
