Replace ALC883 to VT1708B

[satu1991]

Is ALC883 is compatible to VT1708B?

[ShyguyXPC]

what are you asking? Why are you asking?


Are you trying to upgrade a part or what?

These chips are usually soldered onto whatever it is your talking about, unless you have some sort of highly accurate soldering skills, you most likely will have to replace whatever part these are on, Sound card, Motherboard, etc, to upgrade to a different chip.

Given the part numbers it looks like the OP is trying to replace the on-board audio. Why, I'm not certain, if it went out it'd be much easier to just get a cheapo sound card. Are the compatible, the pin-out certainly look the same, is it worth trying to do, most likely not.

[paul9]

They are not quite pin compatible from the picture. They are very closely related, at the least, though. You would really need to look through the data sheets and maybe some reference circuits for both devices to see if it is worth trying one as a replacement for the other.

I have the sloder hot air blower type & i'm going to try it. The problem is the sound chip is hot (fire burning) on my motherboard when i put it ON. So either i remove the chip completly from the board or replace it.

[ShyguyXPC]

most likely going to ruin your motherboard trying to change chips, the soldering points on these are extremely small, and closely spaced.


you mention your chip is really hot, is this when its running?

If so, just buy a small heatsink, same ones used for RAM modules would work, use some thermal Tape/pads and the heatsink, or even Thermal Epoxy if your fine with that.

something like these that come with thermal tape, might work.

As to removing the chip completely from the board, if you do that, their may be problems down the road, with the mobo not able to find it, and causing errors.



Easiest thing to do with situations like this, is disable the onboard audio in the Bios, and just use a dedicated Sound card.

[satu1991]

Its fire burning even i disable. Even a heat sink is boiling!

It is boiling even stanby mode (pc is switch off & the power is plug).

Motherboard is a plug & play system. Just like sound card, i think system sound device is removable.

Its clear you have NO Idea what you are even talking about.

There is no way the sound chip is "boiling" when the PC is off. If its running warm, it may need some time to cool off, but Boiling? No.

Try running a video card, that hits 95 Celsius (203 Fahrenheit ) sometime, that is HOT (and that is with the GPU fan running at 80% of max speed), no sound chips even get near that hot.


and even when its on (The PC), it shouldn't be THAT hot. Sound chips for onboard audio DO NOT get that hot. Hell, most dedicated Sound cards don't get that hot. Aside from a few top end, high end sound cards like those from Creative, even use Heatsinks, Asus's Sound cards have an EMI Shielding around them, and some may need additional power from PSU to help with boosting audio signals and what not, but even they don't get that hot, fairly warm, but definitely not "Hot".



The other thing, How is a Heatsink boiling, for a Sound chip, that doesn't even have a heatsink on it?






Motherboard is Plug & Play does not mean that you can remove the chip. Plug & Play is just a marketing term thats been used since PCI and USB were introduced 15+ years ago With Windows 95/98.


Devices or addons get plugged into the PC, the OS recognizes them, searches for the proper drivers for them if it can find them, installs the drivers, and you can use the device right away, with out having to connect it, configure it, and then install drivers in the OS, before using it.

Thats all it means.

Has nothing to do with removable chips, add in cards, etc.


Unless you are actually using a Dedicated Sound card, the chip is non removable aside from de-soldering it and removing it.

Seriously, reflow soldering is a skill that you will not pick up immediately whilst working on your motherboard. You will cause damage to it. At the very least, practice on some old electronics before you go near it.
You will also most likely need hooks, picks and desoldering skills and equipment before you start. Braid will probably be better than a pump, once you know how to use them.

Ha ha, i'm fabricating syptoms. Ha ha, a sound chip is processing 3GB/s sound to produce 4 MB song for duration of 1 min 20 sec to heat 90 degress. Do your research before talking!

[ShyguyXPC]

3GB/s, Don't think so. 3GB is a hell of a lot more than 4MB (3 Gigabyte, vs 4 Megabyte?) , do YOUR Research before talking.

If your so knowledgeable, and know everything then why are you even asking things in this thread. Just go and damage your motherboard, and be done with it.

90 Degrees, Fahrenheit or Celsius?

If F, then you are crying over spilled milk, 90F is not even hot, 90C on the other hand.

If that was the case, manufacturers would be putting heatsinks with active air cooling on the chips to prevent them from overheating and frying.

there's a reason why CPU's, GPU's and some Chipsets have Active Air Heatsinks mounted on them, same applies for Onboard Audio Chips, if they were getting that hot, they would do the same, but 99% of the chips out there, even dedicated chips on sound cards, don't have heatsinks on them.

F me!

Paul9 my soldering with blower type is fantastic, i have its accessory also. i will do the work even ShyguyXPC what is say because i felt he is bla bla & never done somthing like this!
I know what i am doing but does'nt know what will happen! But still i will inform you guys.

[ShyguyXPC]

yeah, dude I have never soldered before, but I DO Know what I am talking about when it comes to the Temps, functions, data bandwidth and whatever other Bla bla BS you've spouted in this thread already.

Lets have look, shall we...?

3GB/s x 80 Seconds (1 minute 20 seconds) = 240GB of data processed over that 1:20 for a 4MB audio file? Don't think so...

add to that, as I have said, if the audio was disabled, and/or if the PC was off the chip should not be Warm or hot. It could be something else near the Audio chip that is warming things up.

90 Degrees F is warm, but not unexpected, 90C is blazing hot for an audio chip, especially an onboard audio chip, and shouldn't be that hot. Are you sure of what the temp is, have you used an infrared Thermometer to check the temps of the chip?

Also, have you accounted for the possibility that the new Audio chip might actually be larger or smaller than the one you have already?

Or how about the fact, the Motherboards Bios was made to interact specifically with the original Audio chip, and not the new one?


So far you've posted no specifics of anything in this thread besides the exact models of chips, and that the existing one is "boiling".

But yeah, what I said was bla bla...

I have soldering skills and welding skills since that was a vocation that I took up. I've made various electronics before, believe me, soldering on a mother board is no easy task plus even if you can solder the damn chip in the board you have the BIOS to contend with just as Shyguy pointed out. Good luck! LMAO!

[ShyguyXPC]

since its been a week now... hows that soldering and replacement of chips coming along....?
