Further OC i7-4810mq 2.8ghZ using Intel Extreme Tuning help?

Why not run benchmarks such as Cinebench 11.5 and Wprime? These benchmark tests are more real when you test different processor generations. Use preferably Wprime version 1.55 as the version the majority use.

 

Was just about to say, wPrime and CineBench (both R11.5 and R15 are fine) are better for cross-generation comparisons. SuperPI is also good for comparing single-threaded performance.

Through SuperPI and CineBench I've observed that Haswell has a 100MHz IPC advantage over Ivy in single threaded situations, which increases to 300MHz in multithreaded scenarios. This I confirmed myself since my SuperPI results with my 4900MQ @ 4.4 and 4930K @ 4.5 were virtually identical (difference was less than 0.2%)

In other words, my 4930K @ 4.5GHz is essentially a maxed out hex core 4900MQ lol. (4900MQ highest single core OC = 4.4GHz, 4 cores = 4.2GHz)

 

Not for games which use all six of those cores! =D

 

What do you think Your xtu score would drop down to with a ram speed of 1600 on your i7-4900mq ?
2400 ram Consignor gives almost 1100 in XTU
1866 = 1020
1600 =?

 

This is my overclock on 4910MQ stable but normally I set power limits to 70W to lower the temps:

 

That renders the OC useless if you're limiting the power it needs to stay at those high clocks under load.

 

It works for most apps and games that don't load all threads. Only real app I use that is the exception is mediacoder x64 that loads all threads heavier than XTU stressing so I set the power to max of 70W otherwise I have to use max fans to keep it all under 95 degrees.

 

Well assuming a linear relationship between XTU score and each ram speed bin, 4.2 @ 1600 should give somewhere in the ballpark of 980.

 

It likely starts dropping off more rapidly.

 

My laptop: MYTHLOGIC Pollux 1613-A Black Chassis (Clevo P150SM-A)

I raised it to 120A also but it crashed after an hour. I kept the 40X cache ratio and raised the amps by 1 and it's still stable.

A) When do you need to adjust the dynamic cpu voltage?

B) I was playing BF4 and randomly in the 2nd hour, randomly my laptop went into battery mode and my power adapter was still plugged in the wall. I noticed this because my frame rate dropped from 90s to 30s lol, and quickly opened XTU to see what's up. The power adapter was really hot. I checked temps, and they were fine in the low 80s. I unplugged/plugged it back in and i still couldn't get the same frame rate i was at before or to 4.0GHz while my OC profile was active in XTU. I restarted and everything went back to normal. Also at times when i run the same oc profile in xtu for a couple of days and re-do the benchmark the GHz changes at from like 3.97 to 3.98 to 3.91 etc, including the temp.
Is this normal or Is my wall power adapter dying?

 

If that's the case, your machine has a 180W hard limit for the PSU without modding. No idea why it would crash with too-high a current limit... maybe it just overdrew what the adapter could do in that respect? I wouldn't know.

If the BF4 thing is a once-off, that's okay. The OC profile going from 3.97-3.98 happens sometimes too. It'll VERY slightly change something. No idea why it dropped to 3.9 flat though. that's almost a 100MHz drop.

What can I say? Fiddle and see how it works. If worse comes to worst, you could look into getting a 240W PSU and modding it for your machine to suffice any power requirements it may be missing.

As for when you adjust the voltage; you adjust it when your machine is not holding clocks under stress (and it's not a power limit) or when your machine is crashing under load (or off load too; sometimes the low power voltage is screwed up and raising it a little fixes it).

 

I would town down the OC for a bit until getting a larger adapter.

 

yea i been searching around. is the only way really to cut up a psu?
i saw someone mention this X75 Connector Converter - 7.4 x 5.08mm with Center-Pin to 5.5x2.5mm for a converting the ends of a psu to make it fit.
any recommendations of which psu to get?
or i could do this http://forum.notebookreview.com/sager-clevo/681885-recommed-180w-220w-power-supply-p150em-8.html

on the other hand re-ran fire strike!
pretty good!

 

Yeah the only way is to mod it. I'd suggest grabbing one of the 240W P170SM-A PSUs though instead of a 220W. Also, for such large photos you should use a spoiler tag =D.

 

my bad haha

I prolly will go with "Dell 240W ADP-240AB B" with the "7.4 x 5.08mm Female Jack to 5.5 x 2.5mm Male Plug" which is plug&play!

 

Just be aware that the cable uses a thin gauage of wire, I don't think it was designed to deliver more than 10 amps over extended periods of time.

 

maybe i could find a connector with a higher amp rating, or i'll solder.
got both for a total of $80 together, which seems like a good deal. just shipping was overpriced for the connector... other than that good deal.

ALSO my laptop shutdown again in the 2nd hour of BF4 again. 2nd time fudge. This time my laptop wouldn't start. The temps were not even that high again. mid 80 degrees celcius.I took apart laptop and psu to let it cool off just in case.Saw also my amps went back to stock randomly while everything else stayed the same for the oc.
My PSU was hot. Just hot. Not extremely hot but hot. I set an alarm in real temp that if i hit 95 it tells me, but it never rang during bf4.
I'm pretty sure it's my PSU.

What do you guys monitor temps with while gaming XTU, OpenHardware, real temp, or they all the same?
Do you game with battery plugged in, or it doesn't matter?

 

I game with my battery plugged in. It shouldn't matter if it's in or out. I also think your PSU is at its limits. You could simply order a 240W PSU for a P17xSM-A model from mythlogic if you wanted; those can handle the OCs I'm sure. I use playclaw for my overlay, because it has this nifty button that lets me hide it and show it at will without any lag. It's also customizable with lots of features.
My overlay looks like this:

Spoiler

Isn't my game nice and single-threaded? Gotta love seeing 0% util on a CPU man.

 

What game is this? Final Fantasy?

 

Mythlogic said "You may have blew out your OC, damages resulting from OC".
But all i did was use was XTU and my PSU get's super hot. My PSU was always getting hot oc or not.
I'm sending it in just to make sure i didn't damage anything.

other than no crashes so far, and also fun game. looks like FF

 

It is. Runs like garbage. Ever seen a GTX 680 take 80% GPU power to render 10fps of a scene? I have.

Hopefully it works when you get it back. Don't know anything about "blowing out an OC" though. Maybe "blow out your adapter" for a while, sure.

 

Time for FF1 !!! WonderSwan Color port, of course.

The gang vs. Kary:


Airship theme:

 

Pushing components over their rated levels can cause failures yes, especially if care is not taken to cool all parts properly when tweaking.

 

I always had proper cooling, and can't see anything getting damaged in the laptop since i was using XTU and have the default clock settings to reverse xtu if anything unstable happens.
I have the cooling too.
Hopefully it is the PSU let's hope.
I go to Mythlogic Dec6.

Until than, default profile loaded.

will keep you guys updated.
at least i know my stable oc, so when i get a my 240w psu should be good.

 

It can still happen even if you are careful as you are stressing the components with more voltage or higher currents than stock. That's the risk of overclocking.

 

Dell provides processors in the Alienware very high volts up to 1.279v (Oc profile in bios) actual voltage itself is not dangerous, but higher currents than stock = high wattage = high temperature.

 

Voltage itself is dangerous to chips, just as much as temperature. Both contribute equally to wear.

 

When i shutdown my clevo and put it in a different outlet, i saw in xtu somehow it went to 4.0ghZ when it wasn't even OC before. Spooki.
Going to take apart my outlet just to check if wiring all good.
Either way a free diagnostic from mythlogic is no harm done either.

so how bout them 5th gen cpu's haha

 

Dellienware delivers warranty on the processor with 1.279v on oc profile. HaHa. Here at home I have five years national warranty on my laptop and or processor ..But I use 1.2230v. Should have gotten 10 year guarantee at least with this actual voltage .. ..

 

Yes but that OC profile is mostly for a single core and IIRC throttles anyway, hence the actual wear is much less.

 

Not on my processor ..

 

If you have adjusted the settings yourself then it's no longer the profile they warranty.

 

It's just call Dell then the technician come with a new one. They switch if the processor fails. Had a 17-4900mq earlier as they had to switch. Got a i7-4930mx as an apology.

 

well, i guess thats what u pay apple-like prices for

 

The special national warranty on 5years are free. I only pay extra to Dell if I want home support ..

 

i was talking about their premium-scaled prices for their systems in general even without any extras

 

Paid $ 3600 for my Alienware 17 Ranger you see in my signature. Of course without my Samsung 850 pro and OCZ vector. Is it terribly expensive?

 

Very much so, lol. I paid ~$3600 for the machine in my sig; every bit of it. As useful and nice as the AWs were prior to their new update, I could never have gotten this kind of specs for that price. (also note I have a built in 3D emitter and pair of 3D glasses)

 

wow that's a lot, i didn't pay anywhere close to that for mine and it's still amazing.
I guess it comes down how deep your pockets are.

ON ANOTHER NOTE

I'm even more certain that it's my psu failing!
everytime i unplug and connect my psu i keep getting different reads and framerates.

i hope it's that and no internal damage

 

Remember that I live in the most expensive country to live in. Norway
A new medium typical family car costs approximately 70 - $ 75,000

 

To be fair it's a fair bit less than my P570WM was. Then again I paid a fair bit less per KG

 

I had gladly paid a bit more if it was possible to buy more powerful hardware in my laptop .. The laptop could very well have been heavier too if I had gotten more performance ..

 

then it sounds like a p570wm would have been exactly your thing

 

A delicious laptop with the right hardware .. :thumbsup:

 

My PSU started making a buzzing noise and get's warm/hot during bf4.

on another note here'z my 240W dell psu (forgot to upd8 on it), compared to the 180w psu

 

BF4 will be almost maxing the system power draw so that's not too surprising.

 

I was referring to my original 180w psu while not being OC, didn't do that before and have been playing for a long time

 

Buy one Kill-a-Watt Energy Usage Meter so you can monitor the electricity consumption. These are not particularly expensive.

 

what are idle temps for when playing bf4?

i'm getting high 70s and even hit 80 :\

 

I took out my meter as I actually have not measured my power consumption recently (since getting the 980M SLI), I was surprised to find just 380W while playing metro last light. That's with a reasonable clock of 1220/1460, once I get my 1266/1500 at a slightly higher core voltage I will have to measure it again.
