Really no point on that, it's a U-series chip (which are power limited) with integrated graphics. And since you're limited by the notebook's cooling system you can't really do anything. If you want performance, get something else. It's a really nice laptop otherwise though, I have the 2015 XPS 15 and love it. I was looking at the XPS 13 but got the 15 to get the quad-core H series i7 and Geforce 960M, but maybe size is more important than performance for what you're doing.

Sorry for bumping, but it looks like their driver can use the eGPU to power the internal MacBook display with OS X. How did they do that?
I imagine they didn't and that this whole thing was a scam.

If you want lower temperatures while gaming you can disable CPU Turbo in the bios, it will keep the CPU from speeding up to it's turbo speed and save the extra heat. The GPU in the m14x (or m14x R2 or the new 14) is not powerful enough to require anywhere near the CPU power the laptops actually ship with so if you're gaming and not say encoding movies this is a good idea. As a bonus it prevents the GPU from throttling in most cases. Just remember that you did do this in case you feel like turning it back on later. I leave turbo boost off on my m14x R2 most of the time. It saves battery life too.
Re-pasting this laptop is a huge pain, you need to totally disassemble it (I've done it to mine) so make sure you're comfortable with the idea before you do it.
-
Probably, but there are no guarantees. Mine will run at 1150/3000 if I push it. I normally run at 1100/2800 for a little headroom.
-
Actually there is a piece of software that does just that. I believe one manufacturer bought the rights to it, so it is not available unless you have that model. Doesn't really matter as I read a review on it, and the reviewer said it was better to uninstall it as it was more hassle than it was worth.
If you're talking about Lucidlogix Hydra performance is terrible. Even if it wasn't terrible overall the HD4000 is so slow that it would bring the GT650M down to it's level and be slower anyway.
I recommend flashing the unlocked system bios and overclocking the GPU, that really works and can yield good results.

I recently thought about doing this myself. I also have a i5-2500K.
I recommend overclocking your 2500k to 4.4Ghz and if that works out trying for 4.7Ghz. If you're using the stock cooler get something better. I have a Corsair H80 closed-loop cooler but it's total overkill. Stop where ever your chip does. I did a bunch of research on this exact issue lately and found that upgrading to Ivy Bridge would net me anything from a small increase to a small decrease and Haswell chips overclock unevenly and unreliably. Normally after 2 years Intel would have produced something worth upgrading to but apparently they've been spending the entire time working on power efficiency.
I would wait and see what Intel comes out with after Broadwell (which is likely to not improve the CPU performance situation either).
But if gaming is what you're looking to do, buy a better GPU. Radeon 7970s are being fire-saled right now and the "next gen" isn't a quantum leap forward so they're a pretty good buy. When it comes to game performance you're not going to see much difference between a 2500k and 4770k.

Actually, there is a bios image on this forum that has the disable BD PROCHOT option. I haven't actually had the overheating issue, since I repasted my system hasn't hit the ceiling, even with the GPU overclocked. Maybe my ambient temperatures are lower than others, I live in a fairly cool part of the world. I do normally disable CPU Turbo (the CPU is massively more powerful than the GPU anyway) to lower fan volume but I've tested with it enabled without issue.
BD PROCHOT, seriously.
-
The only thing you can realistically do is flash an unlocked bios and overclock the GPU. You should be able to match an overclocked 750M because they're the same silicon with slightly different clocks.
Radeon 7950's are great aren't they? I've got a couple in my gaming rig.
-
I think I'll stick to the A11 bios unless I run into trouble. I had a lot of issues with my desktop when I updated the bios and eventually had to go back to an older version to get everything stable at my everyday overclock again.

hey i read and re-read alot this thread because i found it really interesting for me
you said that this unlocked bios will disable the turboboost on CPU right? so, if i want to play CPU-bound games like GTA IV or maybe next GTA V, disabling CPU turbobost will make my fps drop isn't it? because my CPU can't get to 100% of its power
and one last question, is it safe to use your unlocked vbios @950/1400 daily?
sorry for my bad english, im indonesian, cheers
No, it will not disable turbo boost, some of us have disabled turbo boost because we'd rather have less noise and lower CPU performance.
-
I'm not sure the battery issue actually affects all systems because I've never had it. At this point I wouldn't flash a new BIOS anyway because I'm not having any issues.

I've got to say, having read a lot of reviews, I was expecting to return my XPS 15 as soon as it arrived, but it seems to me Dell might have fixed the wireless issue or done something to make it much better with a Killer card inside, I've got three laptops next to each other, my XPS 15 can see more of my neighbours wifi networks than I've ever seen before, and I'm getting a much better signal for my furthest access point in the house, than any other laptop. The 5GHz router is operating faster than any other laptop, all in all, I wouldn't say this laptop had any wifi issues. I wonder as mine is from the outlet and was delayed a little before shipping, if they have a solution that can be fitted in the factory.
The L521x is pretty close to EOL at this point, maybe they'll fix it for the next version. Better quality screen, fixed Wi-Fi and no thermal issues who knows.
I guess I'll have to wait and see, next step test the CPU throttling.
As for the design, if you've bought the Sony, clearly you're going to say it's a better design, personally I like the XPS, but that said design is secondary to function.

As long as you don't use the GPU it will perform OK. If you bought the i5 version with the GT 630m it may not even have the overheating problem, I personally haven't tested one, I found the 5Ghz performance to be passable for short distances, 2.4Ghz is crap. Apparently the Killer card will help compensate for the issue so you might be able to live with it. I personally love the look and feel of the XPS 15 but I didn't like the fact that it performed on par with cheap economy notebooks that were 1/4 the price.
-
What is the likely hood that this will fail and perma damage my computer?
Pretty low assuming you follow all the instructions to the letter.
-
I can get mine to 1150/3000 before it starts to get unstable. Not doing anything unusual, just afterburner. I normally run it with turbo disabled because it's quieter but I've had no issues with turbo enabled. It's possible you have a low-clocking chip. It's more likely if you have a newer notebook because Nvidia added higher bins to their grading for the 750m and a few other newer models.
My notebook has been repasted with IC diamond which may or may not be relevant.

EDIT: I'm running A11 unlocked and have successfully achieved +365(1200MHz)/+1000 although the GPU is throttling to 405MHz when it hits 64 degrees after 2 minutes. How do I stop this throttling?
I also tried 1180MHz and it throttles to 405MHz after 4 minutes at 61 degrees..
This is at 1180core/3000mem:

If you haven't repasted your notebook with high-quality paste that might very well help. Another thing you can do is disable turbo on the CPU, I have it disabled most of the time because the notebook runs cooler and it doesn't affect gaming performance. I can run my system with turbo on and the GPU overclocked without issues, but every system is slightly different and my environment could be cooler than yours.
-
This is definitely not true, you can use any msata drive you like. It's possible you have an issue with your specific laptop, it's more likely that two msata drives you tried were defective.
I've been using a 256GB A-Data SX300 in my M14x R2 for 8 months with no problems.
-
I would suggest thermal tape, but truth be told the memory doesn't run hot anyway.
-
From memory I don't recall seeing any thick pads on my m14x R2. The GPU and CPU are covered in fairly-generic looking paste and the GPU memory has thin thermal tape on each chip. This picture shows 6 memory chips, which is a bit odd because I thought that memory chips are normally installed in even numbers.

Depending on age there may not be a Windows 8 driver for it. I have a 802.11g USB dongle that won't work with anything newer than XP. "compatibility mode" doesn't work for drivers.
Try looking on the manufacturer's site for updated drivers, if that doesn't work post the model so we can check it out.
P.S. Also try every single port on the notebook.
-
I recommend using the unlocked A11 bios from this thread instead.
If you use the "FPT" method you don't have to use the blind flasher so if you follow the instructions correctly the risk of bricking your system is low.
-
There are a bunch of throttling options in the unlocked bios, I have no way of testing it out because my laptop never gets even close to that hot.
You may want to try disabling CPU turbo first, that will get you more thermal overhead for the GPU and the m14x's CPU performance outstrips the GPU by so much that the loss in clock speed won't be noticable. You'll still be GPU bound in basically every game.
-
respect, Great work!
cant wait for my new M14xR2 to proceed it, too.
UPS means, delivery tomorrow.
what do think about cutting out a Little part (15mm) of the Fan. so a part of the airflow can stream over the PCB and heatsink. i believe it will be help for cooldown Phase.
cheers

That would decrease your overall cooling efficiency, the heat pipes are already servicing hottest components so you're best off cooling the fins on the other end. I'm also hoping you mean the fan surround because cutting a fan is a really stupid idea. It would unbalance it and cause it to rotate unevenly. That generally ends with more blades breaking off.

The color gamut is not great. If you're used to high-end IPS screens it's going to disappoint. I only have an Ultrasharp U2311H and the difference in color accuracy is very apparent when I switch between the two. It's difficult to get a decent laptop with a decent screen. The m14x's 900p screen is passable, but not great. Color gamut is not good and it's very glossy. It's bright and crisp with good blacks so I can take the good with the bad. It's also good for gaming with low latency for a laptop panel. The 768 panel is a cheap low-end POS.

is it possible to flash it on my lenovo y500 with GT650m SLI ?
thanks for reply
Not unless you want to brick it. The replacing the system bios with a totally different model's bios is a very bad idea.

Probably, but no one is sure. I've already bought an XPS 15 (9550) which has both Thunderbolt 3 and an Nvidia GPU so I'm watching for a good solution to show up, although I think I'll wait for the next-gen graphics cards to show up before I actually shell out for a setup.
