So here is the BIG question... Quadro 3600M in a M1710 - Page 16

Well thats no good, just so you know, the more powerful ac adapter will ONLY help it go faster, it WONT help the heat issue and it WILL NOT help your brightness issue.

Those things aside, I'd be happy to buy it, even now, do you have a paypal account? Plus since this thread isn't for selling, we should just message each other.

bump so I can actually find this.

i apologize for beating a dead horse but does anyone know if the 3600m works with the new bios A10 on e1705 i ask because i can get one dirt cheap

ok never mind further researching the new A10 bios do include more nvidia card support but the 3600m was left out and is still not supported oh well that sucks i was going to get it for less than a $100

Too bad indeed, for that price

cheers ...

That's extremely good considering ebay still has 7950's at 200 bucks.

Just to kick a dead horse. I started tiddaling in bios modding a little tiny bit, it turns out someone has already tried modding the bios a little to accept the list of vcards accepted by the m6300. It was good in theory, but bricked the laptop (he recovered via the bootstrap flash method). According to zzpulp the brightness issue might be a little better if you reflash the card after. I might try that with a hacked bios flash to allow my laptop to upgrade to windows 7 and authenticate correctly...see what happens. Probably after the summer, lot of lessons to cover with kids. I have a fx3600m now so I can try stuff.

On THAT note, does anyone have an old 3600M heatsink? The one I got was damaged alot and I suppose I'll test it but I reckon a good chance that with the bending there was that it's a lost cause. Sure I could use my old heatsink but common, bigger heatpipes. AND on that note, some cheap pcicard fans and a new video card fan would be nice. Can anyone confirm a difference between the m6300 and m1710 fans (other than lack of lights) cause if it happens to be a stronger fan I'll pick that right up.

Hi, i have also got myselft a 3600m but i will probably go the hardware way and feed the inverter with a separate source.

My problem is that i bought a e1705 with a burned gfx, does all bios for the e1705 support the 3600m (support as in boot with a picture)? Since i can't meassure, does anyone know or can help me with what voltage the inverter needs to give the ccfl 100%?

I have started to tear down my lcd to try feeding the ccfl, Im down to these pins :

 

- SMB_CLK          SMBUS interface for sending brightness & contrast information to the inverter/panel

- SMB_DAT          SMBUS interface for sending brightness & contrast information to the inverter/panel
 

- INV_PWM         System side PWM input signal for brightness control

 

Ok, if i have understand this correctly DAT & CLK provides a ratio and i will not try to modify that, atleast not for the moment, instead:

 

There are two control signals that come form system to control lamp brightness. One signal is

named DAC_BRIG, which limits current to meet LCD lamp current specification. Another one is

named PWM, which adjusts lamp brightness. This inverter brightness is adjusted by PWM burst

mode. The PWM burst mode is that turning on and off the lamp at rate of 150Hz. The effective

brightness is a function of the duty cycle

 

 

INV_PWM                   142    150     158 Hz PWM signal frequency

                                    3.0     3.3      3.6 V PWM signal amplitude 

                                   30%               100%

 

This is for a acer ccfl, but i have compared with some others and it seems to be almost the same.

-----------------------

New update

I feel like i am having a monologue, however if my meassuring is correct the inv_pwm is pin number 13. I will use the USB as my power source, but i saw someone earlier in this thread mentioning that it was a bad choice of source and I am curious why, if i understand it right it provides 5v and 0,5mA which is more than I need.

-----------------------

New update

Ok, to be honest i got my 7800 to work so i have been using it as reference, i meassured the inv_pwm to 0.7 and according to some data sheets i found it is :

 

Input voltage Low            VPWM_H                                      NV_PWM
                                       V5VALW =4.75～5.2V                   0  － 0.7 V 

 

Input voltage High          VPWM_L                                        2.1  － －  V
                                       V5VALW =4.75～5.2V                    

 

BUT!, when i cut the cable and restarted the computer, the CCFL was still working, this means the IC-controller is set to SMBus mode(atleast i think so.)

 

Next step is to either reroute the inverter board to bypass the IC-controller or modify the SMB_DAT & SMB_CLK.

ITS ALIVE! i tried to film to get some proof but the quality is not that good...

will upload to the tube.

I think i will try to flash it to a 9800m gt

Edited by englund33 - 9/8/11 at 9:51am

It's very good - how feasible is it to flash it back and forth for different gpus?

cheers ...

I dunno how you got that to work.. but it is fantastic!

There is a tricky part.
I have only 2 inverters,both based on MAX8759.
And X1400 and 7900GS card.
If card routed SCLK and SDAT to inverter then must work.But in case of 3600M something is dfferent since isn't working.
Or there is a SMBUS address conflict. (on LA-2881P motherboard schematic graphic card and inverter share same SMBUS signals lane)
But I don't have one to look at hardware.
There is one PWM input on inverter but is always high.No PWM from EC (MEC5004)

By default (on power on) MAX8759 "Device control register" 0x01 address have 0x00 value,that means inverter is in SMBUS mode and lamp is off.
Best approach of this for someane with some hardware skills I think is to re-route inverter signals from video card to JLVDS connector on mainboard (only place,connector isn't mounted)
That means 4-5 wires go from inverter to mainbord and not to video card.

Looking at video from englund33 seems is not using original inverter or at least is not controlled by EC. At 0:26 that is not visible in normal operations,but is visible if you get light from other inverter or other source.

Also using other inverter you loose brightness control.

If somebody hava a data logger can snif SMBUS trafic on inverter to see what.s wrong.

Too bad I can't find or get one 3600 to take a look.

I'm playing a little with inverter part.
Right now since my CCFL was a little old,and I have some free time I switched to LED.Is not finished yet and I think I'm stuck until I redesign inverter with MAX17061 which I can't find in my country.

Now after re-winding transformer and change some components to other required values I can drive with brightness controll my LED stripe (8 pairs of 12 series led).
But until level 5 of brightness all working fine.Below level 5 inverters become warm and very hot al level 8.

I went the simple route and bought a inverter according to the spec i could meassure from the inverter and a pot for adj, driving it with the original vin and usb.

Another way is just to use a pwm for adj. Ofcourse it is a more classy solution to use the original inverter by controling the SMB.

 

Where on the mobo where you thinking of taking the signals from, the connector? I could never find a scheme for it.

 

 

Are all the wuxga screens the same?

What you mean with
Are all the wuxga screens the same?

Most of them are standardized. So 99% are the same.At data connection.

There is a unpopulated socket place on motherboard marked JLVDS,is under video card,aproximate at same area where the one on card is. (version with integrated video,use same cable,so it must fit as lenght)

If you can make some basic measurements with multimeter I'll try to post some pictures to try to find if SMBUS signals pass through video card, from inverter to motherboard.

Well.....I had an inverter and everything set up for an external trial of this....then I come back and see someone has done it...internally.


Congrats to you man, way to go, breathed new life into the m1710.


Nowwww :P Can you tell me what parts you used? A diagram in paint showing what to solder where would be nice...

Hell make it a tutorial and I'm sure it'd be stickied before you even click submit.

Hi. I have both a 9400/E1705 (T7600, 7900GS, A10 BIOS, Vista 32) and M1710 (T7600G, 7950GTX, A07 BIOS, Win 7 64).

 

I have been looking for a post on possible DX10/11 video card upgrades for one/both of these. I have read this whole thread and see some light.

 

Am I correct in summarising that;

 

1. 1600M (8700M) upgrade is possible without issue for both 9400/E1705 and M1710 (but not worth it given cost/performance).
2. 3600M (8800 GTS) upgrade is possible;

• for 9400/E1705 and A10 BIOS without issue
• but for M1710 and A07 BIOS have issue with brightness control on internal LCD (but not on external monitor).

 

The M1710/3600M LCD brightness issue relates to what GPU's are supported in the Dell System BIOS, and A07 came out before release of the 3600M, so was not included. On the other hand, the A10 BIOS came out post the release of the 3600M, and includes support for it. As per matchbox2022, I look forward to a tutorial on the hardware fix for the M1710 LCD brightness issue. GREAT WORK GUYS!

Well, I've gone and done it. Quadro FX3600M in my M1710 (after a bit of minor hacking, as noted above). 3DMark06 of 8080 (Default Clocks). IMHO this is a good upgrade, - if your not replacing your M1710 any time soon. I've previously been using the latest LV2GO modded inf drivers with my Go 7950GTX, but newer games didn't run all that smoothly (BFBC2). This card with same drivers reinstalled fixed all that. (It will run BF3 smoothly, - on low settings). Got card on e-master for US$270 (free shipping).

 

Dim Screen. 

As per you others, I have the dim screen issue still to sort through.

Of you guys that have cracked this one, is there anyone willing to give me a bit more personal input on this via a PM please (I'm not in the industry, but handy with voltmeter, soldering iron etc)?

 

If someone will get me through this one, I'll volunteer to do the "How To" so others can atleast decide whether or not this upgrade's for them.

Hi. As per gabiz_ro above (post #312), I want to play "spot-the-difference" between the M1710 and the M6300.

 

As I don't have one, can someone please supply the motherboard ID info for the M6300 with the discrete Quadro FX3600M graphics card.

 

With this I hope to be able to source a bit more info on the M6300. Thanks.

M6300 motherboard (what I found on internet)
Dell code JM679
Manufacturer Compal model LA-3751P

But no schematic available.

@jimmyp482008
what you have available?

Search for LA-2881P schematic,if you have FX3600 mounted on motherboard then check continuity of signals from MEC5004 to inverter board.

Hi gabiz_ro. (Thought I was posting into a vacuum for a while there). I have schematics for M1710.

I'm still studying these/ learning how/what I'm looking at.

 

1. Looking at the JLVDS (is that the inverter immediately below?)

As you say, pins 5 & 6 appear to be input/output of smbdat & clk (and could possibly be tapped off to the inverter).

 

2. Looking at the JVGA (and diagram immediately right top)

SMBDAT & CLK input/output signals appear to pass through the card connecter, but not the card.

 

As I think you suspect, there is possibly no connection for these signals across the FX3600M card to the cable to the inverter (as it is currently wired)?

 

I have access to multimeter and oscilloscope, so was thinking of buying a spare card to inverter cable and measuring what input/outputs get off card (both 7950GTX and FX3600M) into LCD.

 

WILL DO WHAT YOU SUGGEST FIRST.

 

I'm heading away for a few days, but hope to get into my machine again weekend of 3 Dec.

 

In mean time will try and source M6300 schematic.
