It depends on which model you have... Core i5 and i7 use considerably more power than C2D siblings... so as those with custom ATI 4850 GC...

The current models have continuous max power rating of 241W and 365W for 21.5" and 27" respectively, so that should give you some idea, but it's usually way below that since you're not loading both CPU and GPU 24/7... Previous generation iMacs are around 180W if I'm not too mistaken...

mmm i have the 27" imac and my electricity bill shoot up RM100 for this month. So i was wondering whether this is being cause by my imac.

You've just got the iMac recently...? And you do a lot of heavy stuff on your iMac...?

When I first got my Mac Pro running at a constant 360W, my bill shot up RM 100...

However, I did read of complains in recent months about power bill shot up considerably, even though they don't use Macs...

My March bill shot up from RM 500+ to over RM 750 for no apparent reason... At first I though my GTX 260 I was using on my MP drew too much power, despite the idling CPU usage. This month it hovers around RM 600 when I got rid of the card in favour of HD 5850...

so that means it is my iMac that is causing the increase of electricity. I on my imac all the time and i do web development work. I have housemates you see and this month's electricity bill has increase. So I just want to make sure whether it is my imac that is causing the increase.

i dunno which is better, but from what i read it's best to stick with intel for now

Without prying into details, it's actually hard to lay the finger on the pretty white skin of the iMac... On a more serious note, lower your screen brightness, set up your power management settings to lower screen brightness and send the hard drive to sleep after 10-15 minutes, don't run a gajillion apps at the same time and as a last resort... use power saving lightbulbs

dear sifu,

i have bought a macbook early 2008 with below spec:-

Intel Core Duo 1.83Ghz; 60gb 5400-rpm hard drive; DVD Combo

if i wish to upgrade the hard drive & dvd combo, what is the recommendation model of hard drive & dvd drive. For the hard drive, what's the capacity can support?

thanks

as far as i know, there's no limit on HDD size, as long as it's a 2.5", 9mm-thick SATA. biggest right now shud be 640gb. i can confirm with u 250gb can support la

dvd drive i dun think can easily upgrade. but i suppose if u can find an old macbook superdrive, can get someone with experience to install for you

This.

And you're better off getting an external USB DVD drive.

isnt this an late 2006 model? i have the same model. You can buy the superdrive from ebay and also upgrade to the max of 500GB of HDD, not sure about 640GB hdds though.

^ yes it's the 2006 model..i think he meant he bought it in early 2008

haha, yeah, bought in early 2008 thanks for the advise sifus ~

I'm planning to update my Leopard to Snow Leopard. Would there be a significant noticeable improvement or am i just wasting my money? and also I'm using an IMAC what is the maximum amount of RAM it can sustain?

i didnt notice much performance improvements apart from time machine backups, but the tidier expose is nice also, openCL and grand central is still not big right now, so there's not much benefit of upgrading to SL.

Which imac do u have? Different models have different maximum RAM

Thanks for the swift reply, it's a Imac Core 2 duo, 2 Ghz

Macbook Pro 13" Mid 2010
Intel Core 2 Duo P8400 2.4Ghz
4GB DDR3 Ram

Original Hard Disk : Seagate Momentous 5400 250GB

Upgraded Hard Disk : Hitachi TravelStar 5400 B version 500GB Hard Disk

Before upgrading, went to Machines, Max Studio, asking about the upgrade. Most inane answer came from MacStudio. Best answer came from machines.

Bought Philips #0 Screwdriver RM6.80

Bought Torx T6 Screwdriver RM14.80 (Comes in one set)

Bought the HDD RM230

Testing it out now. Upgrading not that difficult.

mmmm i asked which imac... which year punya model? d white one or the aluminium one?

if C2D 2.0Ghz i think only got two. if the white imac, max 3gb. aluminium imac max 4gb. not sure if got other versions or not

kudos to u for self-upgrade!

anyone know how much for 8GB ddr3 for macbook pro?
what brand to get?

bro, are you thinking to sell off your mbp 2gb x 2 ram? let me know !

im looking for suitable ram upgrade for my imac 27" & mbp too

I think its better to confirm it with the apple care center or maybe you could ask those apple resellers... They do provide RAM upgrading services and also the price.. But I think it would be cheaper to self upgrade... The model for the RAM is 1066 MHz PC3-8500 DDR3 SO-DIMM SDRAM... Should find something similar and should be compatible.
