L502X modded bioses download (GPU voltages and more!)

@ScruffyITA

as far I know, no one had a single brick with any of the bioses posted at this topic.

I'm 99% sure it will work fine, however, when I relase a new bios I allways leave a red text on it to let know others it has not been tested yet.

anyway if you still dont trust it, you can wait until another one try it.

PS: I was thinking about credit the first person wich test a new relased/untested bios by adding some color to his nickname at the first post and giving him some rep points.

 

just tested your 0.85 0.98 bios for the gt525m just reporting that all works well running nicely at good clock speeds keep up the gd work

 

@daryld1988

thanks!
added to the first post ^_^

 

Ha ha lol.

They must all use this much power:
1.21 Giga Watts!?! - YouTube

Where I am it is mostly dead silent- and when the fan is on max it can sound like a turbine-engine at night!

@ZX Raziel

At those clocks the performance probably surpasses the GT 555M!!
(standard clock of course)

 

@capitankasar
Yeah, that's what I meant. Sorry, I was being silly. Thanks again!

 

@utmmyak
hehe, np

@Matix5
lmao

 

I tested
A10 540m
2D PROFILE: 0.83v
3D PROFILE: 1V

Works great.

 

How far can you overclock (if you do) with the 1V?

 

Just installed your 540 83-85 A10 bios. Running like a dream so far Capitan!

 

@Savior and sevenofnine
thanks for the feedback!

added at the first post

@all

need more feedback, specially from the new A10 525m 0.85/0.85

thanks

 

Hey Capitan!

I've just noticed something....

When the fan used to come on for a long period of time, I could toggle it off by changing the power plan from the task manager (Balanced/Power Saver). This doesn't seem to work any more. Have you noticed this too???

 

@sevenofnine

do it happens with only the new A10 bioses?
do it happens also with the original (non moded) A10?

well, the official A10 changelog from dell said something about changes at the FAN, so is posible it is a issue related to the original BIOS, I didnt modified anything else than the GPU voltages and some text at the setup utility.

I also have the power setting to performance allways, the sad part of having an i3 is that I have very limited proccesing power, so I cant limit even more the CPU ^^

 

Hey Capitan,

I've not tried the 'official' A10 bios from the Dell website, only yours. I didn't think it would be something you'd have changed tho, I know you're only able to mod the GPU voltage (at the mo!).

Has anyone else noticed this? It's not the end of the world and I can always just go back to A09 if it causes problems.

I sometimes wish I'd gone for an i5 - I run my i7 in power saving mode most of the time - it can be a bit of a beast sometimes!! Can you upgrade to a mid-range i5? I guess the socket would be the same?

 

@sevenofnine

I considered several times upgreading proccesor, but getting a sandy bridge socket 988 proccesor is not as easy as it sounds.

also the prices i saw for the single proccesor are as expensive as getting a whole new computer with the new proccesor inside.

also called dell and they told me that a proccesor upgrade to a i7 would cost me arround 1000€ plus 200€ from the technician.

In my case I would love to disassenbly the unit and do the task by myself, however 1000€ for a single proccesor is unnaceptable :/

I noticed about this

NEW! Intel Core i7-2820QM Mobile 3.4GHz 8M L3 45W 32nm | eBay

i7-2820QM for $293.99

it could be a very interesting option, but I think is really good to be true xD

however not sure if that offer still avalible, saw also this one:

http://www.ebay.com/itm/Intel-Core-...8MB-/120642126422?pt=CPUs&hash=item1c16d4c256

but that is more expensive.

 

Just to let you know - IT LIVES !!!
But i dont know if i should trust my temps readings , they seem too low , i was expecting to reach 90-91 .C but it only got to 74-75 >C while gaming , i think that cannot be right maybe my gpu temperature sensors are faulty , i dont know but i know the temps should be higher . when i have OC to 800 MHz i was getting 70-71 <C ,

I had my heart in my throat when i started game testing and i was expecting to kill the laptop , but it runs ok , i have had no crashes or artifacts , but experienced tiny bit of microstuttering in heavy battles , now downclocked to 880 MHz just to stay on the safe side .
Thank you amigo .

 

Just tested the new A10 modded bios (0.85/0.85V profile) OC`d with 750/1500/1000 clocks with my NVidia GT525M.Played Battlefield 3 for an hour and temps between 72C-85C at room temperature and no cooling pad...so far,so good no freezing,lags or BSOD...Cheers!!!

 

I don't think it'll add much overclocking headroom. But it might add a little bit. How much overclocking you can do depends on the quality of the silicon itself. Every chip is different.

 

@ZXRaziel

nice temps

@Jovica666

thanks a lot for testing the untested BIOS

added to the first post ^_^

now all the current Bioses are tested at least once

I think some users like ScruffyITA will be pleased to know that this bios is tested with good results hehe ^^

 

The cheapest quad core option is 2630qm or 2670qm. You can find them very cheap on Ebay.

@sevenofnine
There's no disadvantage to having a i7. When your computer is idle. It will use just as much power as a i3 or i5, but it will be much more powerful when you need it.

 

woah, you are right!

nice prices hehe

I think I will definitly take the upgreade

thank you ^_^

edit: arrgg, it dont let me add you more rep points >-<

 

yes, nowe i can give it a try

with the a09 bios and 0.85-0.85 mod i cant get stable pc over 700mhz vga clock.

now im with the a10 0.83-0.83 and pc looks stable also at 740mhz vga core.

maybe i can give this 0.85 a try and look if it give me some advantage in oc the gpu just a bit more

i was thinking in buy an i7 too, but maybe it's a bit useless an i7 wit such a low vga (if for gaming) and for not gaming an i5 a decent cpu too

ive seen that with battlefield 3 my i5 processor never pass the 70-80% power utilization, so will it use the 2 more core?

2 more core means also more heat.... and dont forget that maybe sell our i5 and buy a new i7 will costs us less

 

yeah, I admit the low/mid grade GPU is not upgreadable at all. sadly the only thing we can do is OC, a thing we has been doing over this whole topic optimizating voltages and temperatures to improve it via the BIOS.

but well,it run fine for most of games I play, and i3 is a little low for me, I would need at least an i5 with turbo boost to get decent speed at CPU demanding apps like emulators such as dolphin.

the lack of OC features on the mobile proccesors, and the lack of turboboost feature on the i3 is forcing me to upgreade :s

 

Hey Cap... I'm also thinking in a CPU upgrade for my XPS in a mid-term future... however, there is one thing that seems to be important to think about, before it's done: is the heat sink good enough to dissipate the extra heat created by the quad cores? If I remember correctly, all of the iX with dual cores (mine, and even yours), has 35W of Max TDP (thermal design power)... in the case of the quad cores, this value rises to 45W... if the stock heat sink can hold it, awesome... however, if it can't, remembering that this sink is used by the CPU and also by the GPU, one more chance to make an useable upgrade is to look at the dual core's i7 (2620M and 2640M)...

Here is a comparison table for some iX with dual cores directly from the Intel' site:
Compare Intel® Products

 

@Ogrus

well, I supose the motherboard, heatsink and everything else will be compatible while switching proccesors.

else we will be screwed hehe

but since all the models come with the same enclosure and internal parts I supose it will be fine. (I know there are motherboard changes between 525m and 540m graphics since they double the dedicated video memory from 1 Gb to 2GB but I think that the GPU is the only MOBO difference, it should be ok for proccesors)

well, its a fact that the i7 will drain more power and generate more heat than a i3/i5, but that its normal, I saw several posts of users complaining how hot become an i7 with turboboost enabled and performing exaustive tasks at this laptop.



I know my temps are really low with an i3, I admit that the temperature and battery life are the only good things about the i3 (well, maybe the price too,thats why I bought it in the first place, had no money left for FHD screen or i5 CPU xD, however I am satisfected with the laptop itself ,well I admit I hate the HDD activity led indicator on the back side, I cant see it without close the screen or stand everytime I want to check it )

 

Hey Captainkasar,

Been running your A10 0.83v/0.85v since you released it. I have to say that the issues of the fan running up and down has been working great, but that might be because of the A10 update but the issues. Runs like a charm when idle, no fan switching on and off like it did. I also notice that the side vent when it pushes air, isn't as hot as it used to be with the stock. I don't overclock or anything so this is perfect for me. Keep up the great work!

 

@jiannichan
thanks a lot for the feedback!
added at the first post ^_^

 

Hey captain... looking by this point of view... yeah! We'll be screwed!
kkkkkk

But, as you mentioned, if the different models (dependant by the GPU installed) use the same 'main structure', change the CPU shouldn't be a big trouble for the heat sink... however, by the other side, as I said earlier, when I'm playing Dragon Age, even with the turbo boost disabled (CPU usage is maximized at 95% by the power options, having in mind that have created a GAMER profile), the system reaches some peaks of 81°C in the CPU (monitoring with the CPUID HWMonitor)... althought it is well below the max temperature that the system can hold, I think that it is a bit high, as I don't think this game needs that much of the system itself... in normal use, it keeps between 40-50°C... however, I must say that, here in Brazil, in the region where I live, the average temperature is, normally, well between 25-30°C, which may be influencing this too...

 

@ogrus
mmm, it looks like you have some temperature issues.
you can try the undervolted bioses, and also the hardware tweaking (repaste and remove the dust filter to improve airflow, it really helped me ^^)

 

Yep... as soon as the system itself has the tendency of heat, the enviroment temperature doesn't help a bit... using the CM Storm SF-19, the temperature decreases slightly (if I'm not crazy, the peaks in the CPU becomes 76°C)...

I was thinking about the 0.85/0.85 version, but the 0.83/0.85 seems to be a good choice to!

About the repasting, I'd seen a thread in here, but it seems that there is no more pictures in there... about the removal of the dust filter, I'd seen abou it too, but didn't remember where... can you point me some place where I can find it?

Cheers

 

@ogrus

is this the thread are you talking about?

http://forum.notebookreview.com/del...stallation-cpu-gpu-repasting-56k-warning.html

I used this thread to repaste mine

pretty easy.

about the dust filter, it is at the inner part of the plastic case, under the fan, you need to remove the fan to get access to the dust filter



the dustfilter is like a black sticker, as soon as you remove it the airflow is improved

 

I think I`ll give the 0.83/0.83V modded A10 bios a try...who knows maybe Dell have done something right with this bios version Credits to @capitankasar!

 

Very well... downloading the 0.83/0.83 and the 0.85/0.85... firstly, I'll give the second one a try... if it reduces the temperature a few, or, at least, allows some safe OC for my 525, it's done... otherwise, should try the 'weaker' one...

 

I have a l502x i5 6gb 640gb 7200rpm my system just surfing the net is getting 85ºC
Playing warp it gets 88ºC.

Is it normal?

 

@wendiko

Do you have any cpu hungry app running in the background?

like antivirus, download managers, or maybe browsing heavy flash sites.

try disable turbo boost and change power plan to max battery to see it that helps.

also consider to try a undervolted bios,repaste and remove the dust filter if the problem persists.

 

Can you made a custom A10 bios for the 540M using:

2D PROFILE: 0.83v
3D PROFILE: 0.83v

Please

 

@squallmx

hehe, roger that

I started working on it atm, will upload it on arround 20 mins.

however, from what I read, 540m users didnt had a lot of stability on 0.83v at the 3d profile.

will upload it anyway, wish you luck on the tests

 

@capitankasar

yes i have bittorrent running, eset smart security.

My power plan was the powerfull one now i set to max battery to see what happens.

Will keep an eye on it.

Thanks for the tips!

 

@wendiko
you are welcome
I hope you fix it ^_^

@all

just uploaded new A10 bios for the gt540 requested by squallmx

voltages: 0.83v/0.83v

probably will not be stable with such low voltages, but you may be lucky

need feedback plz ^_^

 

It's fine. As long as you're staying under 100C.

If any of you are having temperature issues I recommend a repaste. Buy a little syringe of nice paste like Shin Etsu. I did it and my temps went down like 20 degrees Celsius

I do have a problem with the A10 BIOS. Sometimes the fan will be idle when my CPU load is at 100%. It seems to respond to GPU load but not CPU load.

 

The repasting is something that I'm thinking really serious to do, in a short-term future... just need to find a good material (paste) to work here...

About the A10 BIOS, same here... after I upgraded to this version, sometimes the fan has been at idle, even when the CPU load is at 100% (seen that when running the tests at OCCT, specially the GPU: OCCT (30' - 1280 x 1024 @ 60Hz / windowed), that reached the higher peaks - CPU = 77°C min / 90°C max (peak) (the package reached 96°C) and GPU = 67°C min / 79°C max (peak))... it's doesn't means that I'm having issues with temperature but, with the A09 BIOS version, as had been reported that the cooler seems to work 'like crazy' (didn't perceived it no one time, maybe because the noise isn't a big issue for me), the temperature didn't seemed to reach its max peak, as the cooler operated even when the temperature was at a lower spot...

Well... really don't know exactly...

 

In case anyone was wondering...I've never reverted a bios back after flashing before especially on a laptop so I was unsure. No better person to ask than capitankasar himself. He responded to my PM pretty quickly. Excuse the typos in my question, I sent it from my phone.[/quote]

Thanks capitankasar!

 

@jiannichan
thanks for posting it

dont worry about the mobile phone, In my case i'm pretty sure my english is really far to be perfect

however you can edit your message and use the quote tags to make easier to distinguisg/identfy wich part of the message belongs you and wich part belongs me.

it may not be clear for some users wich didnt read the original message

thank you again ^_^

 

@capitankasar my system is running @ 65ºC surfing the net.
I will repaste when I have the time, don´t feel confortable to do it now,
don´t have the skills.

I will use your bios, which one do you think is better for me?

i5 gt525m 6gb

Gracias amigo.

 

@wendiko

hey

well, since you are using a 525m, go to the 525m section and I suggest you try some luck with the A10 0.83v/0.83v , this one is the coolest mod if your card support it, it will provide really cool temps.

if you are not satisfected with the OC or it the low voltages are no stable at all, go for the A10 0.85/0.85, it should be stable for most ppl

de nada amigo

 

Tested A10 .83/.83, fails when running games, .83/.85 works fine.

I returned to A09 .83/.85 because the new fan control causes CPU Throttling.

 

@squallmx

thanks for feedback , added you at the first post

yep, as most users reported on previos bios versions, sadly .83/.83 seems not very stable at all for gt540, 525m users seems to have better luck since some other users and me are using .83/.83 on 525m with awesome results

but like you said .83/.85 should be fine for most 540m users

 

Just wondering what drivers you guys are using from NVIDIA, are you all on the latest drivers?
I've been using 275.33 because of crashes when playing video over HDMI with the more recent drivers.
I've just flashed the GT525M 85/85 BIOS, so gonna try the 296.10 version again!

 

@kgh00007
using 295.73, no issues yet.

 

capitankasar u do know that there is 296.10 drivers out now just incase you didnt know

 

@capitankasar, I'm running A09 85/85 on my 525M and with turbo boost turned off (cpu max 99%) I'm getting 77C max after a couple of hours gaming at stock clocks. This is compared to 88-90C with stock voltage, great work man!

I noticed some cpu throttling with A10, the fan seems to be gpu dependant so wasn't coming on with lower gpu temps even though cpu got into the 90's. No Issues with A09, +1 Rep and more people should be giving you Reps for your good work!!
