The M15x throttle? The final solution!

Yes but I don't see any difference between that and the 210W. The 210W uses a thinner cable that doesn't fall out so easily (less heavy) so I use that for now.

I need to measure with a killawatt. I used to have one and even brought it with me from the UK but it didn't work on 120V here in Japan.

 

Not going to get this killawatt. Far too expensive!!

 

Then borrow a ups backup power supply. The ones with the screens can monitor watts. Most of the ones with out that stand up have software that can do the same.

 

Can you link me to an example or 2. Then I will start looking. Japan is so darn expensive! 50 bucks for a simple killawatt. Has to be a stealth buy lol

So rent it for a day. Just don't break it!!

Can't you just get a cheap one from ebay? Power Monitor Monitoring Energy Socket Ammeter Analyzer LCD Watt Voltage Amps | eBay

 

Yeh that is similar to the one I use. You can program in economy rates and work out how much it costs but mainly it shows current power usage as well as max power usage.

 

I bought a cheap meter and it was 30 watts off during low usage and about 70 or so on high usage. And that's against 6 ups backups all reading the exact same watts from 3 different manufactures. Needles to say I do not use it anymore.

 

You can rent these things!? I will have to shop around when I have time. I have none at the moment. 70 watts out is pretty ridiculous. That would be completely misleading especially when monitoring a laptop!

 

Not like that. You buy it, test it, if you like it, keep it, if you don't, take it back.
Me, I tend to keep that sort of thing. Works great when there are potential blackouts lurking around.

 

Just scored 6415 in CPU Mark beating an AMD FX-6300 (6,383). I love this processor! Achieved at x27 --> 3.6Ghz 200/200

 

How are you stable at 27x??

Anyways I will be getting my killawatt tonight. Birthday present HAHA let the testing continue......

Indeed. If I set 27x on all 4 cores I get a blue screen as soon as I press the benchmark button )

Keep us posted with what the killawatt readings are, I plan to get one soon to measure the gtx 780m - i7 920xm combo power draw.

 

Well he has the 940xm after all. Seems to be quite a lot better oced The best I can do in prime is 24x and in games for the most part 25x. 27x across all cores is a pipe dream without a successful manageable voltmod!! I must get my hands on a 940xm!!

The powers that be have decided no kill- a- watt for me tonight! The local electronics store has decided to remove the item from their shelves during the past week! What a shame!!

 

What do you need the kill-a-watt meter for again? I forgot. I can measure total system draw while running benchmarks at x27 -> 3.6Ghz if that'll help.
940xm must be binned slightly higher than 920xm? I won't be trying voltmod any time soon and I probably wouldn't use x27 for gaming, I stick with x23 3 Ghz as it keeps things nice and cool.
I only push things up for benchmarks. I've even returned my 7970M back to 1v as it didn't like being at 1.05v and 975->1000Mhz and I got loads of artifacting and random screen refresh lines.

 

I have got a kill a watt FINALLY!

Ran some tests. At 3.2ghz 24x stable in prime 95 with normal fans at maximum power draw is at 150W.

Some interesting information: Disabling Alien FX (fn F11) saves you 5W everytime. I tested this thoroughly. I also tested the thermaltake power fans that I use for my mod. At full power they pull between 2-3watts each. This means to negate their power draw I have to disable the lights. Another interesting fact is the usb 3.0 ports from the expressport seem to deliver more current to the fans vs the 3 normal usb 2.0 ports. The fans run faster with the same power draw. I didn't notice this before. This was while I was running prime 95 at 24x. If you disable the laptop lcd and use an external screen/projector you save 9-10W less than I thought!

 

Again, why do you need to know power draw info exactly? Surely you've got plenty of PSU headroom? Interesting fact about the express card USB ports delivering more current. I'll try that out with mine.

I wanna compare 210w and 330w psu's and just mess around

My watt meter needs a new battery but I'll report power usage at 3.6ghz when I can.

Sent from my One S running Kitkat

 

Nice! What about the power draw in a combined gpu + cpu benchmark? That has to be way more than 150W.

 

More tests to follow. Once I get bored with command and conquer 1 haha

I finally found what I was looking for .

Amazon.com: Pwr+® Right Angle 90-degree Power Adapter Connector Converter for Dell Latitude ; Inspiron ; XPS ; Studio ; Vostro / Hp Pavilion ; Probook ; Elitebook ; Envy ; Hp Compaq ; Compaq Presario Laptop Notebook Ac Adapter Battery Charger Power S

Amazon.com: BiXPower LC90B Right Angle 90-degree 7.4 X 5.0mm Connector Converter for Dell and Hp / Compaq Laptop Power Adapters: Computers & Accessories

No need to pull the pin from your adapter, just pull the pin pin from this converter and you're all set
Now I just have to find a seller that ships to Romania ....

 

chopsy how do I pull the pin from this? Can you pull the pin from one and sell one to me? Will this make it so I won't throttle in life again?

 

Well, the male jack of this converter should be exactly like the jack from our adapters. Pulling and breaking the middle pin should be pretty easy and it makes it so you don't throttle in life again .
I would gladly pull the pin and send one to you, but unfortunately I couldn't find it anywhere that ships to my country. I'll keep searching.

 

That would be awesome and I would love you forever chopsy ;D have you tried looking on ebay for the parts and seeing if they ship over to Romania?

 

Yep, I've been searching for three days now and besides from the two sellers from USA it's nowhere to be found.

Romania is in the excludes section

 

Damn, I didn't see that part! I tried looking around but they all exclude Romania! How about if I buy them both and when I recieve the items I will send them to your address? And then you can pull the pins out and send one of them back to me?

 

I think shipping so many times would take a lot of time ), not to mention we would end up paying for the shipping several times the cost of the actual product.
But dude, trust me, you can pull the pin yourself, it's not rocket science ). Just brake it, that's all. Use a small tongs or a sharp tool to bend it until it snaps off at the base.

 

Yeah true, are you sure that if I break the center pin on the adapter it would work and mean no throttle? Also Is it better to break the center pin on the battery charger or the adapter? Can you post a picture of the center pin so I know where to pull it off.

 

Let's start from the beginning. What battery charger are you talking about?
The pin that gives a signal from your 240W adapter to your laptop is the central thin pin inside the jack you plug in your laptop ). The signal through that pin determines if the adapter is genuine, but it also limits the power your adapter outputs.

If you remove that pin your laptop will pull as much power as it needs from the adapter to the limit where the adapter trips and shuts down. Considering you have the 240W one, you will never reach that limit even with an overclocked 920xm and 680m. If you had your old 150W adapter, you would have definitely pulled more power then what it could provide and you would have tripped it.
If you remove the pin however, your battery will not charge. The adapter is not recognized anymore and your laptop will not charge your battery.
One way would have been to use two adapters, a 240W or 210W one with the pin removed for throttle free gaming and one with the central pin intact to charge your battery.
Another way would have been to splice your adapter wire and install a switch that would open/close your central pin wire in order to either game throttle free or charge the battery.
I suggested that if we used a connector converter piece like the one I'm searching, we could remove the pin from it, and leave the pin intact in our adapter. This way we could game while using the converter, then when you want to charge your battery just remove the converter and plug your adapter directly into the laptop.

This thread is pretty long, but all the information is stated in the previous pages.




Here are some pictures of the middle pin.

 

Oh I understand now, then I will buy the converter and I will remove the center pin! Is it tricky to remove? And once I've removed it can I run games with my 680M on 24x all cores with no throttling at all then.

 

It should be pretty easy to remove, just bend it a few times and it will snap from the bottom...you'll figure it out .
Once you remove it, you can OC as much as the temp allows you or until you get a bsod, but you will not throttle.

 

Thanks a lot for all this information and help chopsy! I will tell you if it works or not once I recieve my adapter. Hopefully all goes well!

This is the correct one right? http://www.ebay.co.uk/itm/Right-Ang...=Laptop_Adapters_Chargers&hash=item3cc17e8342

 

Sucks I already pulled all my pins
Also an oced 920xm and 680m can pull more than 240w. Just running the 920xm at 24x in prime 95 consumes 150w. Add 100w of gpu load on top and you will be over 250w quite easily. Unfortunately I think we also need a psu id mod or dual adaptor mod to bypass certain limitations to even reach this level of power consumption.

That or simply wait for 20nm maxwell haha

I already brought the adaptor, will my 240W psu with the pin mod on the adaptor be okay for 24/7 gaming and everyday use with the 680M + 920XM at 24x all cores? I won't be benching or anything as I just want to use this for future proof gaming and stuff.

Also I just found my old 150W PSU and I pulled the pin! (It took some time to fiddle around with) It seems that I am not throttling anymore with my 680M + 920XM at 24x all cores! It doesn't let me charge my battery though so I knew it worked! Does this mean I have successfully pin modded?

 

Yeah will be fine! But you should keep a psu around that can still charge. If possible


Sent from my iPod touch using Tapatalk

 

My 240W PSU can charge still even if I have the adaptor right? Cause if I take the adaptor off and use the normal 240W PSU with the pin intact it will still charge. Then if I game or anything I will plug in my adaptor with the center pin mod. And my games feel so smooth it's ridiculous! 680M + i7 920XM @ 24x across all cores on the 150W pin mod PSU is running my games way over 80+ FPS on maxed out settings on games like Natural Selection 2!

Before when I tried to overclock the CPU without the pin mod I would throttle and stutter like crazy in both gaming and 3DMark. I love NBR so much! Thanks to everyone for helping me with everything from upgrading my laptop in the first place to finally unlocking the true potential of my setup! Thank you King of Interns, chopsy, fatboyslimerr and anyone else on here!

 

Matt, your 150W adapter is pretty tough, I'm surprised it doesn't shutdown. Be sure to put your hand on it from time to time to check it's temperature because you're stressing it quite badly ).

King of Interns, I'm looking forward to seeing more power measurements. It would be nice to see how much the power draw is when the cpu is on full load, then for the gpu, then for both cpu + gpu. Maybe we'll see that the power draw is somehow limited and that we need bigger adapters

 

I know haha! I just benched it 2 times in a row and played some games for a while and when I touched the brick it felt like a microwave haha, at least I know how to pin mod now thanks to you chopsy! Once my adaptor gets here my 240W PSU will be a lot cooler and I will be reassured that my laptop is running smoothly! All I need now is an SSD and my M15x upgrade path will be forever completed!

 

We will have to trick the m15x to get higher power draw I have both 330w and 210w with pin pulled so I will do some side by side tests. I do believe however that the laptop itself is still limiting power in

It works! If any of you guys only have 1 PSU unit and want to both game throttle free and charge the battery then get the adapter I have which chopsy kindly linked to in this thread. Now whenever I game I just attach the adapter with the center pin removed and whenever I need to charge the battery I take off the adapter and have a intact PSU! Happy days people

 

Glad to hear it's working. The picture brought me a big smile on my face , nice touch!

 

Nice one !! I wish I had found this before butchering my spare 210 and 330W PSU's :'( :thumbsup:

 

I just returned from a lengthy deployment and have had nothing but heartache with my m15x after I upgraded from stock 720 and 240m to the 920xm and 560m. Constant battle, this. I've been following this thread with great interest and am very, very jealous of the amount of knowledge you all have with modding.

So, long story short, I have the flextronics 240w psu that I bought because I thought I would need it for the upgrades, but sadly it throttles. So all I need to do is purchase this 7 dollar adapter from ebay, plug my psu into for gaming, unplug it for charging? I don't need to yank the pin out? If so I will buy this thing immediately, and kudos for the ebay link! Thanks again.
