EVGA SC17 1080 finally available

yeah. i forgot about that. We'll calculate it out

 

Max power draw at 47x4 and cache at 43x with Imon slope at 50, no offset.

 

So 105.8W....

But your temps.....are LOW for that type of power draw.
now its my turn....gota do your test. 4700 mhz and increase voltage past 1.275v....

@Vistar Shook What's your static voltage for 4700 mhz and x43 cache?

 

1.38V

 

The power draw for 48x and ring 43x at 1.430V static, IMON slope 50, so 114.4W.

 

how about the yellow EDP OTHER? Yellow is still okay, right?

 

EDP other=current limit. You need to change ICCMAX (CPU Current limit) in bios to 200 amps. if its a 1/4 divider then bios value of 800. 600 is fine too (150 amps).

This BGA VOMITBOOK.........
Look
this is 4700 mhz, cache 43, 1.38v same as yours........
LOOK AT THE POWER DRAW........and temps...........what??????????????????????????
and lower score.
even with IA AC DC loadline=1....MSI is still vid boosting?!?!?!

 

Ah ok, I have it at 400 in BIOS, will put 800 then.

 

ok here is 4700 mhz, 1340mv instead of 1380mv.
Now i have power draw and results similar to yours.
I'll set imon slope to 50 and check again.

 

Yeah more power draw than mine at 4.8 and 1.430V. Unless my package power is being reported incorrectly because of the IMON slope, but unlikely judging by temps.

 

Cool thanks....that looks about right with similar temps and all.

 

I set my imon slope to 50 and 1.340v and its showing 59.3W. no need for a SS. Going to try 1.310v now.

 

Ok i did 3 runs of 1.310v and imon slope 50 and got this.

 

I think the only explanation for the power and temp differences (MSI can't possibly have a worse heatsink than eVGA) is probably because since NONE of our boards have an actual VCORE Sensor, we don't know what the real core voltage is, only the target voltage, which is VID. Desktop boards will have something called "Vdroop", which is intel designed voltage drop under load (based on a loadline), which is why there is a setting called Loadline Calibration to compensate for this.

IA AC DC loadline works on the AC/DC input signals to raise the VID target based on CPU requested current, but this is used for adaptive voltage and is supposed to be ignored for static voltages. But it acts like a 'sort' of LLC in a backward way.

Since none of our laptops have a true vcore sensor, none of us know how much VDROOP is present in these laptops. So it may be possible that your eVGA has substantial vdroop, while MSI has less. That's pretty much the only explanation. it could also explain why your temps barely changed when you went from 4.7 ghz to 4.8 ghz. Higher vcore causes higher vdroop also, if there is no LLC applied. But it's pretty clear MSI's power draw is just off the charts. Could be some internal vdroop compensation going on. Without schematics, we can't know...and no one knows where the voltage vcore read points are on the laptop (and how would you take a multimeter to a laptop if it's assembled?)

 

You forgot that the Evgabook have Unified HS. No or minimal load on graphics means better cooling for the Cpu.

 

ok. upped the cache to 45x and got +4pts.
also set current limit to 200A (800 in BIOS).

 

@Falkentyne , your GTX1070 is performing like my GTX1080 overclocked. The max I got was 23400 graphics.....time to up the TDP from 180 to 230 or so.

 

My 1070 only matches lower end (lower TDP I assume) MXM 1080's. From what I've seen, I usually lose slightly to most standard 200W stock 1080's.

 

I assume this is the vbios chip in the center of the photo with the dot?

 

That looks like a vbios chip for sure. Have you tried doing a detect on it with a skypro programmer?
It should detect it if your clip is hooked up and then tell you to use the 1.8v adapter before reading or writing to it.

I recommend:
1) skypro programmer (the best)
2) 1.8v adapter, required
3) Pomona 5250 clip (highly recommended)
4) jumper wires for hooking the pomona to the 1.8v without soldering https://www.amazon.com/gp/product/B01LZF1ZSZ/ref=ox_sc_sfl_title_7?ie=UTF8&psc=1&smid=A3KL3JVC9E1BY6

 

Thanks, already ordered, just takes forever to arrive in Brazil.

Just got home from travelling and the Delta PSU arrived and I can confirm that it works.

 

MSI VID BOOST at work:

http://forum.notebookreview.com/thr...itan-pro-425-review-by-phoenix.801314/page-39

 

I managed a CB run at 4.9GHz, with cache at 4.3GHz.

 

Great job bruh Seems the Alienwares need the new 6 core BGA to be able to match your EVGABOOK in Cinebench R15 +rep

 

+3 pts.

 

Welp there goes my spot on the bot!
+rep

Was fun while it lasted...
What freaking voltage and temps did you need for that?

And wait, are you using 3000 mhz RAM on that thing?
@Vistar Shook

 

Yep overclocked Ram to 3000 from 2666. G.skill ripjaws are pretty good. Voltage a whopping 1.52V, the maximum allowed.

I just tried that.
Laptop shuts off instantly and powers on again in half a second.
Can you screenshot your temps though. Please?

@Vistar Shook

Can you have HWinfo64 running (with the VID and temps visible) while doing the benchmark? (or Throttlestop, whatever).

 

@Vistar Shook ? No temps?

 

Not at home. But temps are in the 90s. Don't plan on running at those clocks and voltage again.

@Vistar Shook

So that means you have vdroop then. 1.52v actual voltage rather than VID would reach 100C in <15 seconds.

Because when I set 1.380v @ 4.9 ghz on mine, I get 90C temps after a few CB runs then the EC shuts the laptop off !

Found out apparently MSI has a built in "loadline calibration" I found out by changing the "DC Loadline" setting from 1 to auto and I noticed that the "voltage" (not real voltage!!! THERE IS NO VCORE SENSOR IN THESE LAPTOPS!! The VID !!!) would drop at load, the higher the load, the more the drop. I don't know if the drop corresponds to what the vdroop is 'supposed' to be, but it does seem like it, but it's very illogical. it's almost like the setting is bugged.

Default DC loadline (2.10 mOhms or auto) shows VID droop.but DC loadline at 0.01 mOhms shows NO VID droop at all, and it follows the approximate override voltage set. And if you set IA AC DC loadline to a higher value, the VID gets boosted by the amount of mOhms of resistance (I set 1.275v voltage, AC loadline=2.10 mOhms (Auto), and DC loadline=1, then i started prime95 blend (AVX disabled) at 4.7 ghz and the VID showed as 1.4v with 78W power draw for 2 seconds, temps were high (MUCH higher than the power draw would suggest) and the laptop shut off. (remember when AC loadline is set higher than auto, the power draw seems to be reported too low). But that means 1.275v + AC Loadline=2.10 mOhms = 1.4v true voltage.

However if AC loadline = 1 and DC loadline=Auto, 1.275v voltage, then the VID is 1.18v at load (!) but the power draw is the same (actually about 4 watts higher) than AC loadline=1 and DC loadline=1 (1.275v showed up as 1.279v VID here) together. So clearly the 'VID droop" isn't real voltage droop.

Mind if i ask u some questions when ur back at your PC?

 

Edited my post @Vistar Shook and @Papusan to say the VID would drop at load (by almost 90mv) if I set DC Loadline to 0 (Auto, or 2.10 mOhms) rather than 1. But the temps would actually be about 2C *HOTTER* than if DC loadline were set to 1 (0.01 mOhms)! So the reported VID is 'vdrooping' by what a normal desktop system would 'droop with' if Loadline Calibration were disabled on a desktop board. But MSI seems to have a built in LLC (even if AC loadline is set to 0.01 mOhms) with no way to disable or prevent it. I mean, that is a good thing, but it seems like the DC loadline value was designed around having vdroop active. So if I'm guessing right, desktop boards have "2.10 mOhms" of vdroop applied (negatively) to the loadline slope (This is a guesstimation. .i could be totally utterly wrong and stupid), and the IA AC DC loadline setting for 2.10 mOhms "counteracts" this by boosting the VID (which is supposed to be applied to be used for adaptive voltage). But the DC setting seems to be doing the opposite of what you THINK it should do. That's why on MSI boards, if you have the IA AC DC loadline at 2.10 mOhms for both (or auto), the VID that is shown at load is GROSSLY underreported compared to the REAL voltage (because 1) MSI is using built in Loadline Calibration, 2) the IA AC DC loadline setting is BOOSTING the voltage on TOP of the bulit in loadline removing the vdroop to begin with.

Well I just confused you guys. Have fun.

 

I expect load voltage was more like 1.420. And still, none of you is able to run your [email protected] 1.270v same way as @Danishblunt say is the normal for many of this BGA chips. BTW... You kill the Alienwares with your Cinebench scores. I wonder if @Pete Light want to compete in CBR-15 with his Alienware.

Have you tried all possible ways? Adaptive volt, balanced power profile etc. Even go back to run IA AC DC loadline default (auto)in different power config setups. Tested with c-states enabled etc. In short test out everything. Maybe you can get a higher score if the chips start up with lower temp.

 

Yeah the vdroop is evident and explains why I run at much higher reported VID compared to other laptops, although the temps say otherwise. I do have a vboost option in the BIOS but it does nothing, I think it is a setting for another motherboad type. AC DC loadline settings doesn't affect the reported VID. That being said, my paste job is crap, having one core running 5C hotter than the others, but this laptop is a pain to redo at the moment, I will wait for the programmer parts to arrive to redo it and I try to get even temps on cores. At 4.9GHz this system is highly unstable, and the CB runs were lucky, most runs stop in the middle, with one core over 95C.

 

Better thermal paste may work better. But it’s Amazing that the Unified Heatsink design can’t suck up the heat from only Cpu when you have almost no load from the graphics.

 

Running at 5C above other cores if you're using 100W+ on the CPU isn't bad at all. It's only bad if the core temp difference gets -worse- over time.

 

5°C above other cores is only bad if the cooling can't keep it cool whatever clock speed you want to run. Some on the forum here advice everybody... You don't need to fiddle with applying new or better thermal paste. Stock thermal paste is more than good enough. As long it doesn't run into throttling teritory or 93°C there is NO problem. Aka you should do nothing, or better say no need for it. What if you later want to increase clocks above the clocks you had when testing? Or take with you your notebook out other places with much higher ambient temp?

 

Whoa, NVMe heatsink actually works...27C decrease in temps.
Before

With Heatsink

 

Yeah, it works. But Samsung ain't the worse in class regarding hot running ssd's. Look at the trash Dell prefer for their notebooks. Rather test with ATTO Disk Benchmark. It will put more stress. Run it 3 or 4 times in a row. Even a single time push temp higher than ASSSD or CrystalDiskMark.

 

Awesome, thank you!I may pick that up to have a backup PSU then.

As someone who's only pasted desktops before, does anyone have recommendations for a paste for the 1070 version of this? I'm a little nervous about messing it up but I'm ready to try it. I don't like having my temps in the high 80's everytime I do anything mildly CPU-intensive.
