Hi, everyone!

2

I have a custom computer with a ASUS P8Z77-V LX motherboard and an intel i5-2500k. I am thinking of replacing the cpu with an i7-2600 that came with a used computer I bought. Does that sound like a good idea?

It sounds like a good idea to me.

Journeyman Geek

@bgmCoder actually yeah

bgmCoder

Hi, Journeyman. I compared them and it seems like it is better. But the main reason I am asking is: do you think I'd need to update the BIOS or anything to go with it?

and, I shouldn't have to adjust my power supply, right?

I should just be able to swap them out straight, no?

Journeyman Geek

Off the top of my head

same generation, same socket?

Sure.

Just pop it in, maybe refresh the thermal paste, and it should just boot right up

bgmCoder

Here's the comparison: cpu-world.com/Compare/491/…

Journeyman Geek

If you were popping ivy bridge on a SB board, maybe

bgmCoder

15:17

I can't overclock the i5 because I don't have enough power.

I don't game, but I run a lot of applications simultaneously, and I run vms sometimes too.

Journeyman Geek

yeah

and the i7 should give you more processors and threads

bgmCoder

Do you think I'd actually notice the difference?

Journeyman Geek

Depends on what you do

I'd do it anyway XD

bgmCoder

I could also swap the i5-2500k for an i5-3570. comparison: cpu-world.com/Compare/494/…

Journeyman Geek

slightly less clear there

bgmCoder

15:21

yeah, it's not so much on the other i5.

The i5-2500k only outperforms on graphics operations, it seems.

Journeyman Geek

Which ought not to be that important

bgmCoder

okay, so I'll do it then!

The other thing I wanted to get some advice on is getting rid of my Control4.

Journeyman Geek

(basically the ivy bridge core i5 has 4 ~~processors~~ cores, but your core i7 has HT, so more threads)

er

bgmCoder

There are 8 speakers in the ceiling, each with a control4 wireless receiver (just a linux box that receives wireless signal and sends audio to the speakers) - and I want to replace these with something.

Journeyman Geek

low cost as possible?

bgmCoder

15:26

not necessarily

Think I could do that with a Raspberry PI?

Journeyman Geek

and I guess you want to keep the speakers?

bgmCoder

keep them, yes; they are already mounted in the ceiling.

Journeyman Geek

I was thinking the rpi, but what about software

bgmCoder

linux?

the rpi would need to be wireless

Journeyman Geek

yup

bgmCoder

15:28

that's the whole problem - I can't run wires to the speakers.

Journeyman Geek

hm

Oh

dosen't google have these audio dongles now?

they do multiroom audio, tiny, low power

Mokubai

@JourneymanGeek Yeah, a guy at work mentioned them

pretty sure I didn't dream that.

bgmCoder

these are decently sized speakers

I don't know the details, but they are not dinky dongles

Journeyman Geek

@bgmCoder hm

Do you need amplification too?

bgmCoder

no, I have a Marantz

Journeyman Geek

15:33

no

some speakers are self powered

some need a speaker amp to boost the signal

bgmCoder

problem is that the Marantz outputs sounds to the control4 who passes the audio to the control4 wireless receivers and then to the speakers

Morantz NR1602

us.marantz.com/us/Products/Pages/…

Marantz is a sound system

I admit, though, I don't really understand what it does....

Journeyman Geek

;p

bgmCoder

The Control4 dealer set this stuff up, but he is unreliable and I'm sick of the entire thing

Journeyman Geek

that's a reciever

so..

here's the question I should be asking

do the speakers have power going in?

bgmCoder

hmm, I'm not sure

I will have to get a ladder and go look

I've seen them before, and know they are hooked to the control4 boxes in the ceiling with them (which have power, obviously), but I don't know any details.

Let me go look; this will take me a few minutes.

Bob

15:42

The big question: why do you want to replace what you're currently using?

What do you want that your current equipment doesn't do?

Journeyman Geek

Bob

O.o

Mokubai

Love the "350 amp (Audiovisual Auto-Alert)"

Bob

I'm more curious about the cheese.

Mokubai

The 16 amp needs a best before date on it tho...

Bob

15:45

And the higher current "fuses" are probably permanent.

Mokubai

(Apply 16 amps for 3 minutes and spread on toast)

Journeyman Geek

laughing cow is spreadable, in general

Bob

Permanent in the accidentally-welded sense.

Journeyman Geek

I'm pretty sure most of them are

Mokubai

@JourneymanGeek That it be, but all cheese is better warm and on toast.

Journeyman Geek

15:48

other than maybe "350 amp (Audiovisual Auto-Alert)"

Bob

Laughing cow ... I think I used to snack on that when I was younger.

I miss my easy cheese-eating days :(

DavidPostill

""Other Idiots from Arkansas", a track from Lewis Black's The White Album, includes an alleged news story of two men who got in a truck accident near Cotton Plant when a cartridge used in place of an automotive fuse fired off."

Cotton Plant, Arkansas

Cotton Plant is a city in Woodruff County, Arkansas, United States. As of the 2010 census, the city had a total population of 649. == HistoryEdit == In 1820, when settlers from neighboring states first came to the Cotton Plant area, it was covered in dense timber and cane. As a small town began to take shape at the site of present-day Cotton Plant, those settlers initially gave their new community the name, Richmond. William Lynch brought cotton seeds with him from Mississippi in 1846, and the new crop flourished. The community was forced to change its name to Cotton Plant since a community named...

Mokubai

@Bob Are you not allowed cheese?

Bob

@JourneymanGeek looks like most of those would make a good heater :P

Journeyman Geek

@Mokubai IIRC he's not ~~a happy mutant~~ tolerant of lactose.

Bob

15:50

@Mokubai lactose intolerance... It's a pain in the arse, quite literally

DavidPostill

@Mokubai have a hat ;)

Bob

I'm not among the super-humans :(

DavidPostill

discovery.com/tv-shows/mythbusters/videos/…

Gun Cartridge Fuse MiniMyth

bgmCoder

@Journeyman Okay.

They are Sonance VP61S speakers

DavidPostill

from Mythbusters

bgmCoder

15:53

sonance.com/product-archive/92850

and there are only two wires going into them - red and black

Journeyman Geek

yeah

which means your current audio system also acts as a amplifier for them

bgmCoder

I don't think they are powered

Journeyman Geek

that makes things a lot more complex

bgmCoder

the speakers plug into a Control4 Speaker Point Console

so I guess that thingy is the amp?

Bob

s/complex/fun/

Journeyman Geek

15:55

it acts as an amp

so yeah

bgmCoder

You probably can't get a rpi that does that, no?

Bob

@bgmCoder you didn't answer: why do you want to change your setup? What does your current setup lack?

Journeyman Geek

not really

Bob

And, no, a rpi does not put out nearly enough power

bgmCoder

Bob - the current system is centered on a Control4 box

Bob

15:56

How is that a problem?

bgmCoder

and the dealer is unreliable, and since it is proprietary, I can't manage or change anything

and another dealer runs $99/hour

My former superior got this started

Bob

Ah.

bgmCoder

I'm completely tired of it.

It's the only thing on our network I am not admin over.

Bob

Not sure DIY will really be better

bgmCoder

no?

Bob

15:57

Is this a multi-channel system?

bgmCoder

what's multi channel?

Bob

2.0, 2.1, 5.1, 7.1, etc

bgmCoder

what?

Bob

Directional sound

bgmCoder

I don't know

the speakers are in the ceiling; there are 8 of them.

Bob

15:59

@bgmCoder Yes. Do they all play the same channel, or different channel?

Is this a left/right/center/rear-left/rear-right/etc. setup?

Or are they all the same channel (mono)?

bgmCoder

uh, I don't know.

You can turn on zones

that is, you can specify which speakers are on or off.

probably

Bob

Not quite the same thing...

bgmCoder

it's pretty elaborate

Bob

There's three basic setups: everything on the same channel, everything on different "standard"/positional channels in one system, or each speaker controlled completely independently.

The last one typically requires special hardware. You can simulate it with the second type, but it's not ideal.

bgmCoder

I'm sorry; I don't know how it is set up.

Bob

16:02

Mono: used as a simple announcement system.

Multi-channel: positional audio for things like watching movies.

bgmCoder

It's probably multi-channel.

it's a home entertainment system

Bob

Independently controlled speakers: for complex PA systems, etc..

@bgmCoder Ah. First thing you need to be aware of: the RPi doesn't do surround sound.

The TRS connector is 2.0 only.

bgmCoder

the wireless receiver unit will only connect to one speaker anyway

the 8 speakers are not connected to one another

in the ceiling

Bob

:\

So the wireless part is effectively mono.

That's a bit easier.

bgmCoder

they are just mounted there in the ceiling. They could be anywhere in the room.

Bob

16:05

You still need to deal with amplification. That's not really doable with just a Pi

bgmCoder

well, I'm not anchored to using a pi

I don't really care (yet) what I use

Bob

As far as amps... @JourneymanGeek probably has better ideas :P

bgmCoder

I appreciate y'all's time and advice

Bob

@bgmCoder If you want to DIY it, you also need to consider the wireless protocol. You can't just "transmit audio".

FM (or AM), as in radios, is probably the simplest, but also not particularly high quality.

bgmCoder

@Bob really?

Control4 uses Zigbee

Bob

16:17

Bluetooth, you're more likely to find standard modules. I don't think there's a standard lossless codec though.

bgmCoder

but bluetooth is line-of-sight, no?

Bob

@bgmCoder You could do that, yes.

bgmCoder

what?

Bob

@bgmCoder No, it's not line-of-sight. Effective range is about 10m not including walls, though.

ZigBee. Would be an option.

bgmCoder

10m... hmmm. how many feet is that....

Bob

16:18

~30

Wi-Fi is also an option, but you might run into latency issues. Would probably be fine.

bgmCoder

I wonder, do you think another zigbee device could talk to the control4 speaker consoles?

probably not

The room is a rather large conference room; say 20x40?

or 20x50

20x40

I think

Bob

> Can ZWave and Zigbee pass streamed audio in full stereo? No

Hm.

=> quora.com/…

> The raw, over-the-air data rate is 250 kbit/s per channel in the 2.4 GHz band, 40 kbit/s per channel in the 915 MHz band, and 20 kbit/s in the 868 MHz band.

Yea, you're not getting lossless audio over ZigBee.

Wi-Fi is probably your best option for a relatively easy DIY wireless lossless audio physical layer.

bgmCoder

it sounds easier

and versatile

Bob

I wonder how your control4 does it.

Perhaps lossy compression. Lossless might not be a requirement for you at all.

bgmCoder

zigbee

Bob

16:23

Anyway, ZigBee is probably more expensive than a cheap Wi-Fi adapter.

bgmCoder

maybe; those wireless speaker points are both wireless AND zigbee

Bob

@bgmCoder ZigBee is a protocol for "wireless".

bgmCoder

oh

Bob

You cannot simply say "I want wireless audio"

You need to pick a protocol to transmit it by.

bgmCoder

okay

(I'm only partially stupid)

(but not completely)

Bob

16:24

Consider the really simple AM and FM radios.

AM and FM are two incompatible ways to transmit audio wirelessly.

(They're also not 'digital'.)

Anyway, a DIY solution would probably end up with a separate receiver and amp. You could probably use a RPi with USB Wi-Fi adapter for the receiver.

As for amp ... shrug. There's cheap USB amps available but I don't know if they'd provide enough power for those speakers. And of course there's the question of your budget and what kind of sound quality you expect. @JourneymanGeek?

(He's probably asleep ... and I'm going too. 'night)

bgmCoder

Thanks, Bob.

Bob

You also need to figure out how you want to power your receiver+amp. Wireless power isn't feasible.

Sorry, when I said "consider" AM/FM, I meant look at them as an example of how "wireless audio" can work. I don't mean you should use them. Especially not AM :P

bgmCoder

16:48

for power, I have access to power outlets

so I can just plug it in

Would it be bad to set up a room event for @DavidPostill 's birthday?

Then we could all get together properly.

That Brazilian Guy

Good thing he didn't say 1965-01-22 then. :P

allquixotic

Actually, since Dec ember is the 12th month, that means 22/xx would be only the prefix for 20 -- Icosaember

@ThatBrazilianGuy yeah, or else he'd be turning 1994 this year
