WOOHOO! i got my 980m up to 69*. only 30 more degrees before i can cook eggs.

Question. I know 4790k can turbo up to 4.4. I only have turbo turned off for battery usage and power save profile. My 4790k holds 4.3ghz on 1 to 4 cores quite often. I thought turbo max for 2 cores was 4.2. Am I wrong? Or is xtu or cpuid reporting wrong? Or is my -85mv undervolt for everything except cache which is -125mv helping it hold higher and longer? I haven't tried pushing my undervolt more. I know it can't hold -100mv for sure. I might still have ~10mv to go. Cache possibly more. Doesn't somebody have -145mv for cache? Should I try and push limits more or should I be happy with that?

 

Stock is 4.4 on two cores, 4.3 on three cores, 4.2 on 4 cores. I'd suggest the 4.3 means you are primarily taxing 3 cores if you left stock multiplier in place. Jaybee has the -145 mV, I can do -115 mV stable but run 4.0 all cores with core -65mV and cache -110mV for extra stability (also use balanced profile with 5% min processor for less heat) (below is max fan).

 

My readings are clearly showing 4.3, specifically 4.28/4.29 for 4 cores. I'm running boinc modules constantly. The xtu reading bounce 1,3 and 4 cores constantly with GPU use. The core frequency is definitely not dropping. Seems odd I am holding higher than what specs show. Very curious about all this as I have a lot of good experience with ARM SOC's and UV but this is a different beast. Very pleased nonetheless.

 

Do you have some xtu graphs? Would be interesting to look at.

 

1080p please.

 

@pukemon: why "be happy" with that? check in 5mV intervalls how far u can push those undervolts, in the end every degree counts and yeah, xtu graphs would be interesting indeed, i somehow doubt ure getting 4.3 ghz on 4 cores at stock...

btw, u 17inchers caught up to third most active thread here on nbr batcave still no. 1

The Batman will over take Batman Jr.

 

dream on

 

yeah. unlikely. more 15'ers than 17'ers unless this thread gets really active. could happen though if good screen options come in. and i am stressing my system again. i don't know if i had a crash or standby caused the crash. when i opened up this morning there were signs things didn't close properly. stressing some more today also while figuring out how/what i'm going to use to make that homemade laptop cooler.

 

only 4.2 on 10 minute spread. it shows 4.3 with more valleys and spikes when just using boing. this pic is xtu stress test since i may have an instability. auto fans propped up.

 

pukemon, can u try fahbench too? I'm interested how it fares...

 

I only do prime95, superpi, wprime and xtu. And I did unigine briefly. Prime95 is the only benchmark that brings batman to it knees.

 

....unless he fights back undervolted/overclocked and thus pimped up benching away atm at my stock settings. will update the batcave once im done

well, i meant temps in solid 90's. like mid to high. i'm undervolted prety well and tried earlier. hit 95*+ with the quickness. like kryptonite for batman.

 

Damn mail is keeping me from joining this group. Check still has not been delivered.

 

Best OC Nvidia 970m stock .993 volt
Max Fan: 200MHz core, 200MHz ram - Valley score: 1703
Auto Fan: 200MHz core, 190MHz ram - Valley score: 1660 Max temp - 66
The auto fan 200, 200 score was lower than 200 : 190 at auto fan, but both run stable. Max fan at 200:190 had a score of 1664, so stones throw negligible. And this is at stock voltage...

Its being built!

 

There was talk about this forum not talking off as fast as the Bat mini. I don't know if I would count it out yet. I ordered mine almost two weeks ago but have been delayed since they were out of stock apparently until this past Friday. Basically I'm still patiently waiting :/ but it's killing me. When the production really ramps up we could see a large increase of users on here. I mean if they are sold out it must be selling pretty well right?

 

Probably higher demand than expected for the 17". This machine is truly a beast for the form factor and power inside. Only downside is lack of screen options which could help boost sales if they ever become available.

 

Agree completely. It's the only thing that caused me to look into other brands. I figured I would just buy the upgrade screen once it comes out and is reviewed and deemed worth it. Unless they do something crazy like add touch making the board incompatible but I don't see that happening.

 

When I DO get it I plan to undervolt the CPU. Are you guys using XTU for that? What about leaving on the turbo mode settings and the peak and hold current time? I'm in the process of reading up on it so hopefully I can get some of the questions answered through Google but there is a CPU stress test in XTU is that sufficient to ensure no BsOD or should I get an alternate program to test temps and stability?

 

the lack of a high quality screen option is what gives me pause mostly. Every other component I'm much more comfortable upgrading later on...

 

Assuming the new screen is compatible its a really simple process to replace. I wouldn't be concerned about that. I'm more concerned that even with the IPS screens the color gamut will only be around 72% covered making it not worth the trouble.

 

Yeah, my dream panel is a ~100% sRGB 120Hz panel. I'm not fussed about it being IPS, tho that's a slight plus. Also, higher PPI screen would be nice, but...

 

Xtu yes. I just tried turning off turbo in power management fro. 100% to 99% and it does t seem to work. Still seeing clock speeds above 4.0ghz. Anybody that read this post care to elaborate and how to disable turbo boost. And yes xtu has stress test for ram and CPU but the de facto standard seems to be running prime 95. Xtu is just a quickie and prime95 overnight for stability. I can't run prime 95 yet til I get my new screws so I can repaste. One head was pre stripped and I stripped another putting it back together.

I'm pleasantly surprised by my chi mei screen. Colors are a little wacko but uniformity, the excellent matte (very good matte on mine, perfect), and only the slightest light bleed in bottom right corner. Color shift is horrible but its a laptop and not multi user viewing monitor.

My old np5160 was LG and the color is much better and the light bleed was let's just say uniform all around the screen so it didn't bother me. Probably would've looked a lot better without any but cheap labor and cheap manufacturing won't help. It's a lottery basically with any brand laptop and screen.

 

My current laptop screen is high(ish) gamut TN, and it's hard to give that up I'm considering buying a relatively cheap calibrator device, to at least not have a blue screen...

 

If you want turbo off, manually set all of the cores to 40 multiplier. If they are still in 44, 44, 43, 42 configuration, (or whatever your processor is set standard) it will turboboost. If you set all multipliers to 40 or below, then you will not have turboboost.

 

Interesting I did not know that. So basically any value above 40 is achieved by turbo boost? Out of curiosity if you have undervolted and are getting decent temps and haven't pasted yet what is the need to remove turbo boost?

 

My old laptop was an m17x r4 and I have to say the screen on it was perfect. Calibrated almost perfectly and the delta uncalibrated was fairly close to begin with. I'll be calibrating mine when I get it so hopefully I can provide some insight to how impressed or disappointed I am with the screen.

 

Well, let's put it this way. On boinc in two months, I finished about 40,000 points of work after not having run awhile on my np5160 with 2630qm processor or whatever. I got boinc running Tuesday afternoon and it's already finished about 25,000 points in 5+ days. Part of that is probably due to 980m demolishing whatever the 540m could do. Running the modules CPU on only is slow. Adding GPU to the equation helps tremendously. My other system ran around 80* ± 5* depending what power mode I ran, CPU and GPU on one fan. I plan on running this system close to 24/7 because GPU temps are so low. It's only peaked @ 65* on boinc and highest I've got it is 69* running unigine heaven. I just want to keep my system running lowest temps possible for longevity. I feel comfortable with mid 80's and auto fans but hope to see sub 80's with no turbo boost. Just running seti@home for now. I want to try other modules soon.

 

It depends on what temps you are comfortable with. My temps stay in 60s to low 70s under stress at 4.0. I prefer that. Due as you will, just looking for long component life.

Also, case temp spec on 4790k is 74 degrees. Cpu temp is basically case temp in laptops.

 

Knocked my multipliers down to 40. Basically knocked a nickel of my temps. ~80* is peak temp now what I'm running. Bouncing in high 50's to high 70's now. Peaking at 82* so far. Thanks.

 

back from the carnival weekend! had a zombie costume and feeling like one now at work as well... *ugh*

time to catch up on the developments here!

actually switching off turbo boost involves deactivating intel speedstep, that way ur cpu will hold steady at its base clock, whatever it may be. just be aware that doing so will prevent it from downclocking at idle / powersave settings!

one advantage of diabling turbo boost is constant voltage being fed to the cpu. since disabling turbo also involves disabling speedstep, the cpu locks at one specific voltage and one specific frequency, whereas stock settings involve a myriad of different voltages and frequencies. on one hand, it helps when trying to undervolt since u only have to deal with one voltage settings, on the other hand running base clock with turbo boost disabled actually gives u a bit of a performance edge, since no matter what kinda scenario youre running, your cpu wont be able to downclock / downvolt due to the lack of speedstep

 

Jaybee83 is correct. It's not truly disabling turboboost/speedstep, but it's the next best thing that is available until we have a bios that allows it... I'm betting patience may give us this in time.

 

oh disabling turbo / speedstep is already possible with the stock BIOS in xtu thing is that u cannot overclock the baseclock in xtu!

 

Why are you making me feel like I need to offer a goat sacrifice, my left nut, and my first born to Prema to be a beta tester?

 

LOL that wasnt my intention can never hurt to worship prema, the god of biosmods though

in any case, its prema choosing the betatester, not the other way round and he usually goes for people hes seen around the forums before for longer periods of time and knows are not prone to leaks (distributing unfinished beta versions of his work) and also not completely helpless when something indeed goes wrong during betatesting. in my case i was kinda lucky, since i only needed to open up my machine twice to get it out of a bootloop!

rest assured, the mod will be pubicly released and available for download on his website once testing has finished and hes convinced that the mod wont crash any systems... so stay tuned

I'm a bit of a hardware newbie here, have a np9772-S at home.

Can someone explain the value of undervolting? I'm hearing it mentioned a lot, but the discussions immediately go over my head. Is it to help prolong the life of the CPU?

 

You can reduce heat with it so yes, it's more healthy for CPU and mainboard too. Usually it's used to control temperatures when you want to overclock or in our case here with i7 4790K, to limit heat and to get quieter Batman

 

Yeah basically to reduce heat and hopefully add some life to your components. Helps marginally with battery life too. Can also reduce fan speed if your temps aree lower thus having a quieter system. Can also help turbo boost hold longer if you have a nice undervolt. And don't forget not all chips are the same YMMV.

 

The "Undervolting" Guide is awesome and I learned a lot from it

 

It both prolongs computer component life and reduces heat. Less heat is the primary purpose. This reduces throttling in some cases, but primarily allows components to last longer. For example, go to Intel ' s spec sheet. They have a max operating temp. For the 4790k, this is 74.4 cel. if I remember correctly (it's 74 and a partial degree ). In any case, this refers to the internal case temp of a desktop computer. Laptops are more compact. With that being the case, even if the assembly temp is lower, there is more heat put out by the cpu the resonates around the cpu. In other words, the heat of the cpu (core temp) is closer to what the case temp max is in a desktop then the measured assembly temp. Because of this, to extend the life of your cpu,you want the cpu core temp to be closer to the max temp then the assembly temp. This does not mean you cannot run it above this, as intel has throttle safe guards built in and an auto shutdown if temps go above. But heat degrades silicon over time. Undervolting reduces heat, thereby slowing silicon degradation, thereby extending the cpu's life span.

 

Thanks everyone, I will read the guide. I'm getting confused with people talking about undervolting and then overclocking. It seems mutually exclusive in my head...

 

Undervolting is removing the extra headroom that is built into every cpu to guarantee that there is enough electricity to run. Once you lower the volts, and by proxy the temps, you then can slowly raise both voltage and multiplier to overclock the cpu while staying within the designed specs of the product.

 

Finally finished reading this thread from the beginning.... thanks for all the links and info..

My NP9772 just hit phase 7, thank you Xoticpc, I ordered on 10th, phase 3 on the 13th, shipped today the 16th. It will be here Thursday/Friday. (EDIT: This was a rush order.)

FYI, you can get it a day earlier by calling and going to the UPS distribution center. My center is really good when you tell them it is a new PC.

My needs have changed and I need to have my primary computer as a Laptop. This is replacing my ASUS Maximus VI Hero with a i5-4670K, with an ASUS GTX 660.

I have a 512Gb ssd I am going to cannibalize out of it and swap in the spinning drive after cloning it.

I have two questions

1. I ordered the stock 8gb single ram stick, can anyone tell me what the make and timings are? If not I will get a matched 16Gb kit. Is there any sticks that have bumped up past 1800Mhz?

2. Has anyone been running this with a BENQ 120Hz monitor with a long run? I have not had much luck with getting the data rates up, most video cards just cant drive the signal clean enough. I have a 35' Redmere 4K rated cable it has to run through, I am hoping the HDMI 2.o will help.

If it does not then another relayout of the office will occur. I don't necessarily blame my GTX 660 cards for not being able to drive a long 120Hz signal, but now with HDMI 2.0 the specifications have changed, hopefully for the better.

Thanks

1) contact your supplier, they will tell you the ram module make and model. Mine was kingston value ram.
What video card?
The ram is up to 2133, but you have to take the keyboard out to get to the ram most likely to use the faster speed. This can violate warranties, check with supplier. two sodimms can be placed under the keyboard, two in the back panel with cpu/gpu. Make sure it is ddr3l for motherboard compatibility.

 

980 of course, My 660 could run almost anything at 1080p at decent frame rates, I wanted the best, within reason, and the 8Gb of ram is going to become more important once the advantages of the Maxwell DX12 memory architecture get adopted. Those who still think of GPU RAM as a memory buffer do not understand what is to come.

The Support for dynamic parallelism, this is a big thing by allowing the graphics engine to move partially into hardware, as Industrial military FPGAs do. Beofer they used to get ahold of a couple custom shaders to do optimize lighting, now they can make a custom sequence of shaders to render the frames in hardware without moving the buffers.

Also the shared memory atomic operations are going to be a huge time saver once the wizards game of code re-learn the arcane bit slicing knowledge the 1970s and 80s. There are still a few elders of code that once relied on parallel multiprocessors for advanced operations in the black vaults, these skills are still well known in the core of the networking world, where I live as a firmware network test engineer. Once these are brought into the light and optimized into the game engines, we will have a big jump in performance.

 

Has anybody though about trying to slot out more holes for the intake vents? Seems like they skimped. I am also still trying to find something proper to make my diy laptop cooler.

 

To answer the remaining questions:
2) unsure
3) it will push 4k. With overclock, def. Usable, but will not saturate the full 120Hz. There are issues with Overclocking now due to Nvidia locking down the stock drivers so that you can't do the previously allowed 135mhz oc on stock vbios. Custom vbios also locked on the new drivers (347 and newer). The community has some vbios mods to allow oc beyond this point, but that is a personal choice. Further, we are looking for a good driver mod to allow oc on new releases of their drivers. That should catch you up.
