L502X modded bioses download (GPU voltages and more!)

[capitankasar]

@ScruffyITA

so, if I am not wrong you flashed a entire 15z BIOS jkbuha made, and you flashed it to your L502X.

that was a bad idea, the golden rule is: NEVER flash a BIOS designed for another system, even them are quite similar, the offsets , addresses and stuff will be different, and chances it will not boot again are high.

the 2 rom

are related to system recovery crisis so a possible usb recovery is implemented, but how?

we were trying to get the recovery method at the other forum (along with another features)
did you got that file from the L502X bios?
I will give a look to it as soon as I arrive at home

@daryld1988
the voltages I changed are only for the nvidia card, didnt modified any other voltages .

thanks for your feedback, nice setup overthere
I will add you to the first post

what were your stable clocks with the 0.85v bios? (to see the improvement over the previus version ^^)

[daryld1988]

with the 0.85 bios my stable clocks where 744/1488/1080 so i got a nice increase from your new bios, my temperature with the new bios is also great it hasnt went over 72 degrees so all in all my graphics card is actually running cooler so therefore safer plus i will more than likely be saving some extra battery power plus im getting extra performance keep up the gd work man

@capitankasar i see you have done the mod to remove the dust filter is this easily done and did it shave off much temperature

[capitankasar]

@daryld1988

it seems you have a nice chip ^_^, mine was stable before at 740, but for some sadly reason now it cant go over 675 clock.

nice OC you have over there , performance gain should be very noticiable.

as for the dust filter, yes it was an easy mod, is just like remove an sticker under the cpu FAN and it greatly improve the airflow.

[daryld1988]

@capitankasar i reccomend u to try the 0.83 for both bios off yours and who knows we might get your card back to the 740 clocks you have the same exact card as me and with it being undervolted i think theres alot more potential left in your card yet,

as for the dust filter mod does it require you to open all the laptop up or is it possible to remove the filter another way

yes, those rom are inside the bios rom. in the same place where the nvidia bios is.

ive tried many things, but looks like it wont load the files since my usb drive light didnt flash.

i think i have to ask for an rma to dell to get it back in action.

@daryld1988

yes, taking the whole laptop appart is needed, since the machine will be opened you can also repaste the CPU and GPU, it will also help to get temps even lower, and since you are using also the 0.83v bios, you will be really far to have any temperature problems again
(0.83v+repaste+dust filter removal=no temp problems anymore xD)

I will test the 0.83v version with my machine, I hope I will get also some temp improvements without crashes and maybe a higher OC too

I will also try to relase a 0.83v/0.83v version for the gt540m card, someone may take advantage of it

@ScruffyITA

sorry to hear that.

well, another L502X user who got an error while flashing a OEM bios PMd me for a BIOS recovery method , we tried some stuff without any sucess, thats why I said there is no confirmed recovery method at the moment for L502X.

I hope we will find it as soon as posible, it will make BIOS mods easier and will help a lot of users with corrupted bios like you, but as for the moment we dont have anything yet.

so yep, sadly contacting dell may be the only solution for the moment

[capitankasar]

@all

since daryld1988 had a great experience with the 0.83v/0.83v BIOS, I also deciced to relase a modded version with similar voltages (0.83v/0.83v) for the GT540m board users, the 3d voltage is really low, that may result in gamming crashes for some users, but it may improve OC or stability for other users and will definitly decrease the temps.

feedback plz! ^_^


edit:

I decided to flash the 525m 0.83v 0.83v version daryld1988 tested, and it seemed to improve temps and OC stability
I was able to OC core from 672 I got stable with the 0.85v/0.85v to 710 stable with the new 0.83v/0.83v modded bios, made some tests and no issues yet

[daryld1988]

glad to hear you went for the bios capitankasar the 0.83 0.83 bios really is great in every way so many things to gain from it better gaming performance lower temperatures and most importantly it is also more than likely extending the life of alot of our internal parts of the laptop due to the lower temps great work

[Cyb3rfr3ak]

With the 0.83/0.83 mod, my BF3 crashes on every start (tested 3 times).
Gt 540m

[capitankasar]

@daryld1988

yep, it seems stable now with the 0.83v, and got my stable OC increased a little, nice idea

@Cyb3rfr3ak

thanks a lot for the feedback ^_^, it may be stable for you with the 0.83v/0.85v version ,flash the 0.83v/0.85v and check if the problem persists
