A couple of guys here have told me my CPU has been throttling heavily during my benchmarks and to try throttle stop.
Today I took their advice and I scored my highest score ever on firestrike!! I wish i could thank everyone , but dont remember who it was who pointed it out to me. My firestrike was 9772, physics 11669, and combo 3640. This was my first try and saw a immediate improvement. But I really have no idea what options i should be checking off ect. here are some screen shots of throttle stop. Please take a peak and let me know what i should change. thank you for your help.
Oh yeah almost forgot, system is i7 4930MX, two 780M's SLI, 32GB ram, and Raid 0 set up.

No, the voltage is way higher than necessary for 4.3GHz and the other screens do not match the screen shots I posted in other threads.

In your throttlestop photos , the first 4 are in the bios and you show how the settings are still terrible, but what did you eventually set the bios at before booting into windows and then using the intel extreme utility to overclock?Mr. Fox likes this. -
Yes. I generally start by setting the BIOS overclock values equal or greater than what I plan to do with XTU and ThrottleStop. After flashing the new BIOS you need to open up XTU and disable the stupid Turbo Package lock thing.

Yes, i actually printed out both links to your posts with all your pictures of setting up hwinfo64 and intel xtu. The only thing is in those posts the only bios screen shots you have are of the ones you say are horribly messed up. lol
Should we set up our bios like you had it in your post before you went into windows and changed everything?
These are the settings from the photo, please let me know what to turn off or on so i can use your settings from xtu and hwinfo64.

The performance is messed up, not the settings. The settings are correct, but the system malfunctions no matter what values are set in the BIOS. Disable the stupid turbo lock thing with XTU and you will be fine. After doing so, the BIOS settings will actually work.

Each generation processors, increasing performance per clock frequency. This means that the processor performs better at the same clock frequency than the previous generation processors. The only major drawback with Hotwell processors is that it is much warmer than previous versions of processors. -
I have read different answers on this but wanted to ask you guys what your opinion on the matter is. Currently , thanks to the help of members if this board, I run my 18 (i7 4930mx) @ 4.3ghz round the clock. Using throttle stop and hwinfo to control temps I finally run my games at the speed that was promised at purchase.
My question is do you think I'm taking lots of life off the CPU by doing this? What temps would you consider safe to have a 4930mX running at while gaming,benching ect?
Also what is the lowest volts you have used with a 4930 running at 4.3ghz?papusan likes this. -
If you're sitting at 90 degrees or higher all the time, you're not helping your CPU at all. If your temps don't cross say... 85? You're definitely in the clear.

Ok thanks guys. Wow, then why does Alienware have the volts so high in the bios overclocks? I guess they have to make settings with the crappiest CPU in mind?

CPU silicon is very resilient. While it's ideal to keep it below 85C, the reality is that as long as it's not hitting 100C you're in the clear. It's certainly not desirable to be running your CPU in the 90C-100C range for hours every day, it's unlikely to ever cause the CPU to fail - at least, not until long after other critical components are likely to have failed through normal use anyway. It's the significantly higher voltages that many overclockers go to that can tend to kill chips rather than temperatures.
'Course, lower temperatures are always more desirable. Finding that sweet spot of clock speed and voltage can take a while but is worth it. The stock voltage on a CPU is almost always far higher than what the chip will actually need, because the voltage is set so that the vast majority of the CPUs that come out of the fab - even the worst few percent - will run stable at their rated clock speeds. Unless you're unlucky with your silicon, you can often drop the voltage quite a bit, even when overclocking. And voltage has a larger effect on temperatures and on power consumption than clock speed does. Someone correct me if I'm wrong here, but I believe that the heat produced scales linearly with clock speed but scales with the square of the voltage? -

I thought I´d start out using the Dell stock OC settings for a performance reference level in prior of tweaking. please find the out of the box results with stock factory overclock settings below.
My rig is the one and only famous Dell Alienware 18
- Intel Core i7-4940MX
- 32GB RAM
- Dual NVIDIA GeForce GTX 880M (2x8GB) in SLI
- mSATA SSD SAMSUNG EVO 840 1TB
- Dual SATA SSD SAMSUNG EVO PRO 850 1TB in RAID0 configuration
New system out of the box where the 80GB mSATA and the spinning HDDs were exchanged to SSD devices in prior of turning the system on for the first time.
A clean install with Windows 8.1 Enterprise edition was made including the office SW and SQL Server 2014 software.
I have also gathered latest versions of performance testing software, including Intel XTU (not installed as of yet. I have tested versions 4 Through 5 earlier, but the software Always crashes when clicking on the [settings] link at the top right of the window. Are there any major differences between v4 and v5? Shall I stay with the latest version v5.1.1.25?), ThrottleStop and some other famous gadgets.
In prior of gathering the Performance reference results, I changed the Bios High Performance Setting to Dell Stock Overclock Level 3 (OC LV 3) with the factory settings as of below (btw these settings were also used from the beginning of life during installation of all software now present in the system.):
Extreme Edition BIOS
Extreme Edition Core Ratio Limits OC LV 3
1-Core Ratio Limit 46
2-Core Ratio Limit 45
3-Core Ratio Limit 42
4-Core Ratio Limit 42
Override Turbo Settings ENABLED
Long duration PWR limit 71
Long duration Time window 28 (This is actually set from factory. I have seen that 128 is sometimes used, and thought that it might be an error from factory, but it is working well.)
Short duration PWR limit ENABLED
Short duration PWR limit options 85
Reference test results using FUTUREMARK 3DMARK
------------------------------------------------
Fire Strike Ultra - Score 2445 ( NVIDIA GeForce GTX 880M video card benchmark result - Intel Core i7-4940MX,Alienware 0FT9KT)
Fire Strike Extreme - Score 4558 ( NVIDIA GeForce GTX 880M video card benchmark result - Intel Core i7-4940MX,Alienware 0FT9KT)
Fire Strike - Score 8447 ( NVIDIA GeForce GTX 880M video card benchmark result - Intel Core i7-4940MX,Alienware 0FT9KT)
Sky Diver - Score 23664 ( NVIDIA GeForce GTX 880M video card benchmark result - Intel Core i7-4940MX,Alienware 0FT9KT)
Cloud Gate - Score 25903 ( NVIDIA GeForce GTX 880M video card benchmark result - Intel Core i7-4940MX,Alienware 0FT9KT)
Ice Storm Extreme - Score 159063 ( NVIDIA GeForce GTX 880M video card benchmark result - Intel Core i7-4940MX,Alienware 0FT9KT)
Ice Storm Unlimited - Score 136652 ( NVIDIA GeForce GTX 880M video card benchmark result - Intel Core i7-4940MX,Alienware 0FT9KT)
With this configuration the system is rock solid and cool - perfect for Daily use, even though I would like to have some more CPU Power for Heavy development and database use.
Fans are spinning up fast enough to take care of the heat for this moderate Performance profile test. Not top-notch performance, but I will come to some tweaking further down the line.
And by the way, the system has not yet been repasted, but I have all the tools (liquid ultra) and printed disassembly manuals ready. Just need to take a deep breath before I jump into Work, if I ever dare to do it.

Dear Mr Fox, I just installed XTY latest version and performed a first benchmark using dell stock OC LV 3 in Bios A10.
This is what came out:
Intel Core i7-4940MX CPU @ 4600.0MHz - 846 XTU marks on HWBOT

A too low xtu score even if you use the win 8.1
Stop using dell stock OC LV 3 in Bios A10. Adjust rather settings in the bios and enter the correct values in Xtu.Gunnar Snellman likes this. -
Dear Mr Fox,
with some tweaking using XTU I performed another benchmark, now looking better. I am decreased the multipliers to 43x43x43x43.
I am touching 100 degrees Celcius with the XTU settings used for performance test so the CPU will not take no more. I need to repaste if I shall continue this or my pants will go on fire. The system runs stable (one hour now - will let some 3DMark11 run continously with fans on high speed. Temps around 85-95ish.
This is what came out at first:
Intel Core i7-4940MX CPU at 4300.0MHz with an 0FT9KT motherboard - 930 XTU marks on HWBOT.

Yes, things are playing along with me .. but I will have to repaste if I want to increase the numbers...
I tried to install wPrime 2.10 but the exe crashes all the time ... not 64-bit compatible ?
Cinebench R15.0 works fine ... CPU test just finalized ... BANG ... thermal shutdown ... can´t get the heat away from the CPU.

well i cant open the laptop mr.fox , i have little or no information on how to open up the laptop dont want to screw it up , what about gpu over clocking - whats the max i can go on it can the voltages be unlocked for the gtx 880m .

Take a look at this.. NVIDIA Kepler VBIOS mods - Overclocking Editions, modified clocks, voltage tweaks -
A question that concerns me is the XTU recommended value of Turbo Power Max and Turbo Power Short Max of 4095W. Is this really correct? I feel it will burn the CPU to ashes?!

Hi Gunnar. No, that's not like using too much voltage, which can cause damage, especially if the excess voltage is sustained or repeatedly applied. The amps/watts are not static like voltage. That is removing the lid, so to speak, and letting the CPU run wild and free, drawing as much power as it wants and needs, or as much as the motherboard will allow it to. Worse case scenario is the potential for a drop in performance instead of being finely tuned, but if the motherboard imposes power-handling limits all you are accomplishing is providing ample power to the extent it is usable.

I was wondering how I could reduce the energy, i,e, the heat, in the processor by reducing voltage, and still maintain or increase the clockspeed? How far can I go in reducing voltage for the 4940mx without bricking my system ? Have you tried reducing voltage?
Does reducing voltage make any sense at all ?

That's the scheme Intel uses with their Turbo Boost and Alienware just follows.Gunnar Snellman and papusan like this. -
You must use LIQUID Ultra with Hotwell laptop extreme processor and overclocking...
4x4.3ghz is no problem on these laptops with a much better thermal grease. The main problem With Alienware 18 is that the motherboard has a watt limit so you do not have the opportunity to a hefty Overclock on both processor and graphics card. This laptop has simply not enough watts to processor, hardware and graphics cards.
The new Alienware 18 was a downgrade compared to previous version (Alienware 18 r2) Intel has a share of the blame since they mounted Fully Integrated Voltage Regulator on chip (fivr) so Hotwell was warmer than previously Ivy processors. Dell on its side has cut the fan speed as the fans are estimated to have, and that they have a useless fan profile in all their new Alienware laptops. On Alienware 18 you can not mod a power supply with 2 power supplies due watt limit on motherboard (Max watts = 1 power supply). In array is all power settings in bios totally wrong whether you use OC profile or standard clock in bios. Dellienware goes backwards into the future. Everything becomes now just worse and worse. If possible, try to obtain an Alienware 18 r2 or the hottest Clevo with desktop processor.
I hope we meet again in the tread or forum.

Maybe I will go through with the repaste on the dellienwares ... As I have never tried this Before I wonder if will last if I do it once or will I have to repaste over and over again ... ?
Now I have one of the Machines running on 44:44:44:44. It has been running 3DMark 11 Extreme since yesterday afternoon without overheating ... Processor temp is between 70 and 92 .... The GPUs are between 65 and 75 degrees running 930-970MHz.
If I load the system with wPrime 1024 or CineBench 11.5 or R15 .... BANG ... Thermal meltdown ......
I'll Place a note here again to let you know how things went....

If you use Liquid Ultra and do it right you won't need to repaste for a very long time.
See this post for examples and application tips: [Death Match] Thermal Paste Showdown: IC Diamond vs Noctua NT-H1 vs Liquid Ultrapapusan likes this. -
As I said; All Hotwell processors are boil hot during benchmark tests with an ok Overclock. It does not go without Liquid ultra. Follow the guide of Mr fox about applying Liquid Ultra then this becomes very good. Mr Fox has also created a tear down video of Alienware 18.
Good Luck :thumbsup:

Gelid GC Extreme, IC Diamond, Notcua NTH1 or something are the best non liquid metals. Liquid Ultra is in a league of its own but can destroy aluminum

I am using Gelid GC Extreme on my GPUs right now and it's doing a nice job of keeping them cool. It's also super easy to clean up if you need to repaste. IC Diamond has always served me really well, and it is truly an excellent product. But, nothing can touch the durability and cooling capacity of Liquid Ultra. It's awesome. With a Haswell MX blast furnace CPU, nothing else will do.

I just picked up the delivery at the local post office with liquid ultra and liquid ultra pads. Might go for the liquid ultra but the pads seems interesting too. Not so greasy to deal with. Guess I am just a little scared of that the fluid liquid ultra will damage any components if I screw up.
Well, I am awaiting Gelid Extreme as well, and I have already an IC Diamond kit. Might be going for Gelid for the GPUs and liquid ultra for the CPU, as the GPUs does not really reach the high temperatures yet, due to lack of knowledge to overclock them.

I read somewhere that the BIOS lockes down the available power for the CPU to 55W. Does the usage of XTU override this lockup? I mean, I am running XTU right now and have followed your exquisite tips entering max power usage settings in BIOS and XTU to 85W. Might be a silly question, but I have learned that this overclocking business is twofold, and there seem to be only one place to get accurate information -- Mr Fox and papusan posts. So please bear with me for a while, while I am getting the hang of it ;-).

Just ordered a new Alienware 18 with the 4940mx and dual 880m cards. Yes, I know that I should know better, but I need one system for overclocking lab tests and one reliable system for work. Seriously, this is fun and that is what it is all about.
I noticed that Dell released two new models of the 13, 15 and 17 inch laptops, but no news about the 980 configs for the Alienware 18. Sad, but it seems inevitable that the Alienware 18 will be phased out. This is another story.

Yes, XTU will override it. Also, use ThrottleStop and set it to start as a Windows Task during logon. It will apply the settings when it starts so you don't have to use XTU every time to implement the settings.
