I buyed the PSU @ CEG

 

So my P770ZM has the Killer 1525 installed and I'm getting this problem where when I download over wifi I get a huge amount of System Interrupts listed in task manager (~12%) and the entire computer lags and will eventually just turn off. I'm going to get an Intel card instead, which is the best one?

 

7265ac is for your machine.

 

How and where does one adjust the VRam? I open the Nvidia and all I see is the core clock. Also what are the hazards it undervolting, I've got the laptop at 4GHZ wonder what else might happen if I do the process.

 

You wouldn't be able to change the amount of vram, but you could change the memory and core clock speeds in a program like MSI Afterburner.

 

I'm looking into it with the Nvidia software it came with but I cannot seem to find the VRam adjust

 

I need help with the i7 4790K Temperature, since the place where i'm staying is hot when it is noon (around 33-38° C). My CPU temp when i'm rendering is so high at 90-99° C. So aside of using air conditioning and how to undervolt or adjust the CPU core on Intel's XTU. Any guide?

 

You need an overclock program to be able to adjust the vRAM clocks.

 

Take a look at the links here.

So i'm not experienced about undervolting, is this considered undervolting and is it stable? Should have learn this thing before this

 

That looks like it is undervolted, as to stability you should run the built in CPU stress test. If that is fine and it doesn't crash you would want to run your normal programs and some games to see if it is stable during a multitude of loads. I usually test with Prime95 for a few hours but that is with desktops not laptops, not sure what the best thing is.

 

Okay noted, will update soon. Ty

 

Yes, -60mV Core Voltage Offset is undervolting. That's at stock settings - Turbo Boost. Save it as a profile. Cold Boot PC - shutdown not restart. Open XTU after starting PC to see if settings are still the same. -60mV. Then test it for stability. You can use the Stress Test in XTU. I prefer OCCT for stability. http://www.ocbase.com/
Test Settings

I change the Options to cutoff the test at throttling temps 95C°

Run at max fans (Fn+1)

 

I'm cool just using the stock setting. Just learning to undervolt so that my temperature wont go crazy at 99°C when i'm rendering my works. XTU and other Tuning software really confusing me and takes me hours of googling/youtube just to understands a few idea of undervolting. This forums help me a lot

 

If you have questions, feel free to ask here or in the P750ZM thread. Because of your high ambient temps, underclocking may help bring down temps too. But that can be looked at if needed. Max fans will help a lot.

 

What's an average temp in OCCT? I just ran it and saw 90C on the hottest core, average was 83-86C for each core. It ran the full 4.2GHz stock turbo the entire time.

 

Tried to run OCCT for 1 hour but it stop at 17 minutes because it reach 95°C cap. Still having high temp after UV to -60mV but much better than before. Not sure if that is stable or not.

 

I think I've found my sweet spot of a 35 undervolting, stable 4.19 GHz no MAX FAN tops out at 95 C with no throttling during ETU stress tests.

 

Depending on ambient, that is fine, but xtu isn't the most stressful test. Use it and if a crash, modify the voltage accordingly. I can't say more without knowing your settings.

That is because of ambient being high. I can't speak to the stability, but rather want to know if you are doing heavy processing? If not, see how it ramps on temp under normal use. Also, are all turbo multipliers set to the same number? (I.e. All at 42 instead of staggered) if not, do so and see if you can achieve extra undervolt. Otherwise, lower your multiplier. Also OCCT runs the cpu hot. What are other temps from other stress tests?

 

Getting about 55 C on Idle and the temp fluxes between high 80s to mid 90s when stressing.

 

Idle at 55-60°C, 80°C when playing GTA 5 and when i'm rendering after effect footage (all core is 100%) is at 96°C. And my multiplier is the stock setting (44, 44 , 43, 42) <--- is this it? So i should make it the same?

 

No undervolt? Only 90C°- you're good.

You were stable for 17 minutes. The test only stopped because of the temp cutout. On stock you could drop to -70mV and try again. Temps should come down a little. You, actually, want to crash, find instability, and then decrease the undervolt.

Of the usual stress tests I use, OCCT is the hottest and the one that finds instability. I will add other tests when I find what I think is the lowest stable undervolt at the multiplier. Then Linpack is hotter. I don't use Prime95. There's a lot of negative feedback with it and Haswell.

 

Come at me, Linpack don't got nuffin on my 4800MQ if it's at stock.

Don't mind the low score; I didn't close all my other programs when running.

 

Oh yeah, i'm working rite now so cannot do a stresstest. But bro, you help me a lot. Ty very much, getting a sense about undervolting so far.

 

I crie a little inside seeing your temperature. Was tuning to have that max temp without having to lower the multiplier. Need that horsepower...

 

Ha, don't feel bad. +80mV and +300MHz and I get +15c on my CPU. Linpack would kill me dead. Don't feel bad.

Just make sure your heatsink has good contact with your CPU and repaste if necessary. People have gotten P95 stable at 4.6GHz in somewhat cooler temps; I'm certain you can manage a cool 4.2GHz in what you have.

My room is about as hot as yours; well over 34c in the daytime with huge humidity.

I did a lot of work to get my CPU where it is right now =D

 

And there these thing that was on my mind, so if i undervolting the CPU, why the performance isn't affected? Or is it? Then, did the 90°C temp is normal and bareable?

I never take things about computer hardware so serious before this, i pay people money just to overclocked my Dekstop render unit ( i7 5690x i think) and now i'm super regret because i dont learn it myself before i bought this laptop.

 

never too late to learn!

Umm... let me give you a crash course to my understanding of this:

Voltage, Amps and Watts are related. Usually V*A = W, but it doesn't use the lowest amount of A that it can under load.

Lower voltage = less heat produced, more A drawn. Overall less W drawn (to a point).

Lower voltage is also unstable, which is why stress tests are helpful (but not absolute). I could run stress tests all day and then BSOD in hearthstone (I've done it before). The objective is to get the lowest voltage possible for your clockspeed for TEMPS and Watts which is also stable. If you lower voltage enough, your machine might actually require so much more amps that your watts and heat actually increases. There was a user who was trying to undervolt his 4700HQ to keep it from TDP throttling, and below a certain voltage point he started getting current limit throttle, and raising his current limit fixed it, but he had higher heat than with a higher voltage point and lower current limit, so he ended up raising his voltage (though it was stable) as it reduced his heat output and power draw.

Your 4790K uses so much though that I don't think you'd be able to undervolt so much to trigger what that 4700HQ user was experiencing. So right now, lower voltage until stable. If you want to increase clockspeed, then increase voltage to a respectable number (say 1.27v for 4.5GHz) then start dropping it as much as possible. When you find a crash, up the voltage back some. When stable, keep it. But don't forget to work on your cooling some too.

 

No worries! Learn it now. I am too. If the frequency doesn't change - throttle, performance will be the same. 4.2GHz at 1.3V is the same as 4.2GHz at 1.2V but lower temperatures with the lower voltage.

90C° is hot. It's not overheating and not throttling and not thermal shutdown. So, it's normal and bearable. Lower is better when it comes to heat and electronics and that's what you are trying to do undervolting. If 90C° is your peak temperature when you stress the system to it's max in your usage, I wouldn't worry about it at all. Of course, I would continue to monitor temps.

@D2 Ultima That desktop background looks familiar. What about the start button?

 

I use Start 8 so I don't have that XD.

I haven't found a badass enough desktop picture that I've liked to replace it, and I'm not really in the mood for hawt women on my desktop anymore.

 

Classic Shell here. I saw I could change it and thought - Gargoyle. XD I like the dark color of that desktop. So, it's staying for now.

My work desktop background

 

also i realise most of User describe voltage (1.2v, 1.1v etc) and where to change that thing in XTU? only see mV.

 

Your core voltage is set to "default", no? You can change that to a constant if you wish. "Default" adjusts the voltage up and down as you adjust clockspeed up and down. For example: "default" voltage for me is 1.048v at 3.5GHz and 1.085v at 3.8GHz. You'll need to monitor your voltage during a lightish stress test (like XTU stress or Throttlestop's TSBench) and see what it peaks at. If you've undervolted, simply add back the offset (I.E. I have 0.9976v on my 3.5GHz with a -50mV undervolt, so my default would be +50mV).

When overclocking, you don't want to work with offsets; you want to apply the manual voltage. So your "core voltage" slider that's at "default" in XTU, you can adjust that. For my 3.9GHz OC, because "default" voltage is unstable, I added a manual voltage of 1.1v to see if that works. You'd be adding a manual voltage, and then decreasing that voltage as time goes on. For simple undervolting, using "default" is fine. If you're lucky, you can OC and keep "default" and still use negative offsets to undervolt.

Please note: setting a manual voltage then adding a negative offset is possible; I could theoretically set my voltage to 1.2v then add -200mV and end up with my same ~0.99v that I have right now. It's just kind of convoluted, and I know of no benefit that this brings.

 

Ohh you mean by adaptive voltage? Mine is default i think because i notice a change of voltage depending the core uses and clock speed. I'm setting my clock at 4.2ghz and -60mV. Havent tried it yet for temp. But will do when im back home.

 

Stick with the voltage offset for now.

At the bottom of your XTU you can add items to monitor. Click on the blue wrench (circled in red in the image) to add items like Core Voltage, Core TDP, etc.

Look to the left of your Core Voltage Offset slider. Where it says Core Voltage. You are at "Default" in the XTU image you posted.

 

No. Adaptive voltage is "my voltage will go down as my load/clockspeed goes down". Static voltage is "I will run at <insert voltage> 24/7".

What I was talking about, as @Bullrun pointed out, is "default" and "manual" voltages.

Desktop board makers like ASUS/MSI/Gigabyte/EVGA/etc are all utterly retarded and don't use the terms intel uses (in XTU and apparently by their own definition) for all their settings, so most often around the net, "static voltage" is simply what others call "manual voltage". Please note: all the terms we give you here are for XTU (and possibly your BIOS) and mostly deal with laptops. It's not that our terms are wrong, but most people who use desktops are accustomed to old or vendor-specific terms.

 

They all use their own terms and handle them differently too in some cases.

 

I see, got it. That clear me up. Cant wait to tune it up again.

 

It's becoming fun!

 

I started to do a -50 undervolt.
When i tried to cast videos to my media player, it gave me problems and started rebooting windows.
So then i tried -30 did the same thing.
When i did these undervolts the setting applied fine it was just as soon as iI used theWindows cast to device or at random times the system rebooted
Now when ever iI try to do any undervolt - 15 system still reboots.
Is it something wrong or myCPU don't like undervolt?

 

That's completely normal. Your chip just isn't good for low voltage.

 

This was a thing now eh? no more GTX 980 'M' stuff

 

Are you using XTU to undervolt? It's the Core Voltage Offset? How did you stress test? Does it reboot at stock settings? As D2 Ultima said your chip may not like low voltage. My chip couldn't go as low as other chips at 40x multiplier.

 

you could try static voltage as i do, due to C7 States it doesn't matter that much if the voltage is applied 24/7 or in my case 2/5. My CPU didn't like UV either when using offset mode, since i use static i am stable @ 1.08v from stock 1.19v using four times x42 multiplier.

i want that card, but i don't need it in my ZM, 980M with OC is pretty on par with a Desktop 970 or even a bit above which is more than enough for 1920x1080 Gaming in my opinion, for 3k Screens it would be a pretty good boost tho. But like i said my 980M is even stronger than my 780Ti @ 1200Mhz was, when using GW2 + forced HBAO and Reshade, i had overall less fps than the Ti but the 980m didn't dip that deep when effects are getting spammed.

 

Nvidia is certainly rockin the laptop market. AMD better get in gear, or they'll be left behind. It looks like Nvidia is pulling ahead in the performance per Watt war.

 

Yeah, laptop 980 is Nvidia's middle finger to Fury Nano.

AMD was like: "Yeah about that Maxwell efficiency? It can kiss my red ass. We reduced Fury X by 100W while keeping 90% of its performance. Cool, eh?" (Remember ATi is Canadian).

NBR saw Nano and was all like THAT SHOULD BE A MOBILE GPU!

Nvidia saw this and was like: "NOT IF WE DO IT FIRST. Let us show you what we can do with binning. WHABAAM we'll put a FULL FREAKIN' 980 INSIDE A LAPTOP and let you overclock the shizznits out of it!!!"

 

You play Guild Wars 2? cool and HBAO are good? Going to try Reshade soon since it was so dull

 

Can the new card even be installed in our laptops? If it is full 980 it's pulling 165W theoretically and the MXM bus is only rated at 100W. So does it need some kind of extra power adapter? If the power figures are right you can say goodbye to the lower temps we've seen with Maxwell so far.

 

So does that mean your CPU is running at 4.2 whenever it's on or does it downclock like normal? I'd much prefer that to the offset voltage but I still need it to clock down when not in use.

 

You can save different profiles in XTU to run over-under clocked, volted, combinations.
