40C?! What kind of cooling is that? Liquid nitrogen? AIO water cooling modded for the laptop? Now I know why doesn't it throttle for you

 

I would not rely on that output for sustained 3d load of course. Where did you see the peak rating?

 

LN2 is -190C. No AIO water. I'm using an AC unit.
That example was to let you know...If you can't get your cards to optimal. You will never know what they are truly able to do.....One day I would try to get it cold and then gage it's real performance. Hang out side or in the garage. Run a few test, then come back and post. I'm pretty sure your numbers will go up. While doing so...Gage the different levels of temps to see where you need to be at using room temp later to get the best performance there.

What do you mean?
These power supplies were tested using the p570wm3 so we know they go up to about 880W with just two power supplies. And up to 440W using 1. You were over there when we did all this testing. So i'm kind of in the dark as to your questioning?

 

That was measuring from the wall right IIRC?

 

Oh no, I just meant that somehow everyone usually has some form of problem with the stock system and you are like "where's... the problem...?" a lot of the time.

It's as if all hardware you buy just decides to be amazing for you =D

 

We are all going by from the wall. Since this is what everyone is capable of doing. This is how we get a generalization on how to potentially gage what the watts are. And since this works. We generally keep using it. IIRC
The real problem with this is when people use faulty meters. Then I could see where it would present a small issue. I have 7 and they all read exactly the same. So I'm going to go by that. I had two of those cheapy meters that you plug your device into and they were both off by as little as 20W and as big as 100W. Which we seen in the Clevo thread where I posted about it. Once I found something that actually worked. I stuck with it.

LOL. Your funny.

Truthfully, I can't accept everything is broken out of box. And trust me, I have had some of the worse hardware out, but I can't be bothered with cussing it out all day. If I did that I would get nothing done and we would never find out the hidden secrets.
It might not seem like it, but there really is a method to my madness...

Our problem is we need to find out what true stock is. And that generally is not what reviewers post because they have little to no time to figure out a review unit. And they also can not really mess with it's configuration. That part falls on us as a community to figure it out. Once there, then we can go up to see where we should be and need to be.

 

Yes but we would expect a 330w notebook supply to draw up to around 400w to supply that 330W to the machine (and be within spec) so peaks of 440w is not surprising based on that, though pounding it at that all day long is not going to be a good idea of course.

 

Well something is definitely wrong with either the bios or vios or maybe both...loaded up Gears of War Ultimate Edition in windowed mode and lowest factory core clock with 74C was 1825 mhz...however in Fire Strike it throttles under 1800 mhz to the mid 17xx MHZ. Something is really fishy here...

 

That was my intent! =D

I can agree with this. I usually hunt and hunt until I determine what's really broken or not if anything's wrong. Sometimes things have innate issues (like how logitech audio drivers don't like CCC) but for the most part there's usually a way to make things work. Either way you keep doing you.

Mmm if only people actually reviewed things. I look at many desktop hardware reviews and see 3-4 times the attention they'd put into a laptop. It's sad. But what can ya do besides review a unit yourself huh?

 

Apparently not. Two people just posted saying they thought 330W was not enough. And there is no way your getting a legit 400 watts out of this system using a single 1080N and over clocked quad core cpu.
This is at 4.7Ghz and 150/500 which most can do. Stock bios and EC.


Meaker, that 440W was me trying to find the PSU cutoff point. Not some every day use scenario. Maybe that is where the problem lies.
The P870DM2/3 is not breaking 400W with a single 1080N GPU. Let alone hold it.
And if the PSU was Max watts, you would not see anything above 330W. That's why they do not say max watts.
19.5X16.9=329.55W <----If this was the max then you would lose power at 330W.

The part a lot of people forget is that it's not locked at that. So when this number changes...guess what...so do the watts.
19.5x22.5=438.75W
or
20.5x21.5=440W

I don't know what formula they used but this is just a generalization

I think it still changes even under ln2, but i would need to ask about that though...

PS: Mine do not stay locked while playing GTAV either.

 

PSUs are rated for delivered power not consumed power.

So a 330w PSU that is 80% efficient will consume 412.5W from the wall to deliver it all within spec. The Delta should be a bit above 80% efficient at full load.

 

Okay and?

Edit:
Please do your math based off of real numbers and let me know what that comes out to.
440W is the number to use. Thanks.

With this. I'm able to game at 1911 solid, but if I hit a temp of 66C it drops to 1898. Now, if i cool gpu to 62C, it will go back up to 1911 and hold.
Can you try this to see if you can hold it?. And keep an eye on when the change occures. My range is 62C(Clock raises back to normal) to 66C (Clock lowers)


Edit:
At 1949 it drops to 1936. And it's still holding at 70C
At 1936 it drops to 1924@76C and return once temp hits 72C.

So now you have your range.
42-47=13mhz
52-57=13mhz
62-67=13mhz
72-77=13mhz
82-87=13mhz

 

Now there's the thing, much like overclocking every sample is different, you should be able to expect 400W to be in spec and run for a reasonable length of time (hot so keep it uncovered and in a cooler environment if possible). Beyond that is down to the quality of your PSU and the input voltage (240V is more efficient than 120V).

Beyond the rating the efficiency is going to tank so your 440W from the wall is going to be around 350W to the machine and seems like a reasonable design margin to me from Delta (being a well known company).

All I am doing is explaining what you are seeing to others and when they are out of spec so they know where they stand.

As an electrical engineer I don't need to run the exact figures to do so

 

I get that, but since no one is going to be doing 412W why the detailed explanation? No one is getting anywhere near 350W.
How come you didn't use this detailed explanation in explaining your power mods?

 

They might if they try running a single PSU with a single card setup.

As for the power mods if you are hardware modding a card worth as much as a titan-x I would hope you understand the full implications of what you are doing *shrug*

 

Example:
You know....You do have a machine.
It can run a single card and over clocked cpu.
You can run a single psu with dual cards.

Instead of just grabbing answers out of thin air.

Yeah,that last part did not make any sense what so ever.

Example:
Someone gave you advice or you found information on how to do it. You didn't just take it apart and do it. So when people asked about help with it you didn't give help, regardless if the card cost 10,000 dollars or 5 dollars is a moot point.

No worries though. I totally get your point of view.

 

The warnings about your warranty being void I put on it should hopefully be warning to those paying attention but you can't stop those who are not

The only PMs I have had about it have been about physically finding the things so far, I'm not sure if I should be worried or relieved.

 

I'm confused.

I made Ramen a while ago. It was ok.

Hope everyone else had good meals today!

#LoveAndPeace #AndScience #AlwaysForScience

 

Mmm miso base?

 

Tonkotsu or nothing

 

I've been there before. Worst I've ever been was a meal once every couple days (I was in my early 20s, no car and no one to give me a lift to work during the summer between years in undergrad and no financial aide until school started). But, had a good meal yesterday, although I am healing from separating a rib from the cartilage a couple days ago.

In other news, my desktop benchmarks at 5.0GHz on my 6700K have been posted on HWBot if anyone wants to take a look...

 

Was Chrome video corruption fixed in the new Nvidia driver?

 

Just some cheese and ham sandwiches for tea today, I do have some nice mature cheddar though

I've not personally run into the video corruption so not sure on the driver front.

 

Sucks to hear about that situation back then. Though I just meant I felt like making a pack ramen for dinner, not really that I was scrunting for food (this time).

silly pack ramen, sorry D=

Mature cheddar? Wonder what that tastes like. We usually only get one or two kinds of cheese here T_T

 

It has a lot of bite and flavour to it.

 

Meaker = Academia

Johnksss = Street Cred

Which one is real? I think I know

 

What up T! Hope all is well and the family is doing good!

 

where would @Mr. Fox be placed in this listing? working class? haha

150% the preacher. Spreading the good word about not buying overpriced soldered stuff if you can help it.

Now... where do *I* fit?

 

Aren't you the friendly book writer that completes every argument with a lot of research?

 

I think he was speaking more from a benching point of view. It takes a lot of work to get into the top 20 for the USA and a lot more to get into the top 10.

 

YES. I'LL TAKE IT.

 

First results with new Ram.

 

Yes, we are all fine! I'll give you a shout later

 

Aight, sounds good.

 

False choice in this case, why does it have to be one or the other?

 

what brand? stock or tweaked timings? (im guessing g.skill at stock xmp timings) i managed to get 2800 mhz stable, tightening the timings and running memtest86+ overnight for stability. still no dice with 3000 mhz *ugh* ive gotten it more stable (as in being able to directly set and boot to 3000 mhz without in between steps), but its still coughing up errors in tm5. same with 2900 mhz, unfortunately, although that one is way more stable. so its 2800 mhz for now...

G.Skill xmp1

 

Haven't run memtest86 so not sure if they are completely stable. Were stable enough to run bf1 for 4 hours yesterday though.

 

When running Time Spy and Firestrike what do you change for optimal settings. The only thing I have changed so far is GSync off and set to performace. Are there any other settings that can improve upon my score?

 

depending on BF1´s memory usage, that doesnt have to mean anything also, there are varying degrees of stability, especially since some minor errors dont have direct consequences in everyday windows operation. the longer u operate non-stable settings though, the higher the risk of system corruption at some point.

 

What are the temps in your GPU? mines running at the stock and default Nvidia Settings but i overclocked mine CPU to 4.5

 

Thanks, I will run memtest one night here over the next few nights. Does it need to run 8 hours?

 

My GPU temps run in the low 60's to mid 60's for these tests and mid to upper 60's when running BF1 for extended periods.

 

what about Crysis 3? mine goes up to 85

 

Sorry, haven't played Crysis 3. You are running 2 x graphics cards though where I am only running 1 graphics card and have the vapor chamber (dual GPU heatsync). When I was running the single GPU heatsync on my 1080 my temps were in the upper 70's to low 80's while playing BF1.

 

I was a little off on temps but here was a comparison. First picture was the single heatsync in BF1 and second picture is the dual heatsync in BF1. This was only with about 30 minutes of play I believe. If I play long sessions they go up a little more.

 

Double post.

 

just start it right before u go to bed and check it when u wake up again in the morning ideally 8-10 hours, the longer the better.

 

Mine took just over 10 hours to run... By "default" it did 4 passes of all tests
