to apple gurus,

i dont know what is the problem, i've been using mac all this years but when recently i bought macbook black, it has been restarting randomly which pretty annoying. how could i avoid this? i was preparing for an exhibition slides on keynote .. now i have to re-do the whole thing again. i went to library/logs i could not find any panics.log for karnel pannics

please.. i only want to hear the possibilities this could happen from an expirienced mac user. pls dont spam. thx




p/s: could this be due to my ram upgrade to kingstron v ram? but someone from other forum does not seems to have such problem even on heavy task.
any idea anyone?

Apparently on Newegg's website, some Macbook users are having problems with the Kingston Value Rams.

Try using with your original RAM and compare?

kwekeugene,
thx. i read abt the same but strange many ppl claimed not an issue to them. perhaps v ram they just do random checks rather then 'select' ram which they test each n everyone of it.

man .. i hope leopard wont cause this problem for kingston v ram. else time to put up this ram for sales or use to for mac mini (need to get one then)

u updated your mac??

i think it's the RSS....random shutdown syndrome......

EDIT:

read this up..

I had a same MacBook as yours that gives me a problem also even after a firmware upgrade. I can't restart it after a shutdown. I have to hold the power button for several seconds in order to boot it up. Sent it to VR Tech for warranty claim. Turns out that there is problem with the logic board and they changed it for me. Maybe your logic board got problem as well.

hope its not caused by the kingston value rams.coz i m getting it tommorow..but after reading this thread,i may hav to delay my purchase..

most shops sells kingston value rams...rm240 for a gig...is dat the standard price in LOW YAT..coz planning to get it there tomorrow

if you want to purchase RAMs for Macs...please do purchase Patriot RAMs. They run well on Macs compared to Kingston Value RAMs

babyk,
thx for ur input
but could u at leat let us know where can we get such ram n how much does it cost?


timber,
i dont have any problem. indeed my mac does not require any f/ware upgrade when i purchase it. it's already updated. only mostly on security and os update. it's just abt a month old. anyway, there was no problem booting up. i just have problem when i do my keynote n few days ago when iwas watching movie on VLC, it restart twice. i hope it's not logic board problem. damn i hate long delay for service

you can get it at C-zone Lowyat Plaza

The price is almost same as Kingston KVR

babyk,
thx

babyk...

r u sure it has d same price?i juz browsed through the product on newegg.com...its written that patriot rams are certified by apple..n i dont think its at d same price as KVR.nway i ll go to LY today or tomorrow to reconfirm the price..

thanks

pukarix,
pls update us here ok
i need ur info
thx

^^^^so i m d lab rat ere issit??haha

nway its starting to rain,most probably not goin today....btw,wat if i ve bought d RAMS n its not compatible,could i send it back?or would they accept an exchange?

This post has been edited by pukarix: Mar 24 2007, 01:06 PM

pukarix,
u r not the lab rat, u r just sharing ur exp

btw, i think they should accept

I don't know whether this is logic board problem or not la.....
but 10 of my friend send to VR service centre for the same problem as you, 10 of them also get claim a new logic board......
hope this help you....
thanks

Well, i dont face random shutdown problem with my Kingston Value Ram which i bought from C-Zone

btw, i only upgrade 1 stick.. : ( too poor..
So i am using 1 stick of 1GB + 1 stick of 256.
For the first few day, my apple did act weirdly.
When i wake my MB up from standby or sleep, the screen will turn orange for a while, then back to original color.

But after few days, no more such problem

cutekid,
which batch was it? and it's core 2 duo or core duo version? how long does it takes for them to actually change the board? and i have bad xpirience with apple technician in m'sia especially the shop at midvallet machines. a simple thing that i asked abt upgrading ram and hdd, the tech said it will void warranty and no way i cld do it manually, i said it's even stated in apple website, n he goes bashing abt it. that is the simple example. mayb i should give it to mac asia instead.

btw, this happen drasticly when i was using keynote and on extended display 24".

Hmmm..those Kingston value RAM pricing are quite tempting for me to get a 1GB and plug into my MBP. However now gotta think twice.

BTW, i got an extra 1GB of ram (Kingston as well) from Apple Reseller during the purchase and so far no issue. Wat's the diiff between those Kingston RAM sold in Apple Reseller and those found in normal PC shops in LY? The price BIG difference leh.

neekun,
i had the same q. but perhaps those kingston in apple reseller are SELECT ram rather the Value Ram
check on my post 3 link

Yeah those are "Certified" Ram which will works without problem.

can we have a list of certified RAM for mac ? price if possible and where to get
thx

ok guys....i ve got my 2gb RAM..

i was at dis shop in lowyat...mac reseller or something..on d same floor as c-zone ...

i asked them about the pricing of a 2x1gb stick..it was rm1200..the difference is on the ram..on the certified ram its written KTA..but on valur rams its written KVR..but then i saw d shop selling also corsair RAMS.n i asked him whether its compatible or not.n he said yes.so i took a look at it n remembered d codes written on d RAM..

wat did i do next...went to czone,asked the guy to show me the codes on the CORSAIR RAMS...n it was d same code..so i asked him whether i can try first b4 buying..he said go ahead.d guy even let me borrow his screwdriver..

d macbook restarted n it was running..checked the system preference,n d status was OK.so i paid for it,n now its running flawlessly.hope nothing happens..

c-zone
CORSAIR RM215 perpiece..

if u r planning to get kingston value rams,most shops are selling it,but d cheapest is cycom..rm195 perpiece...

i ll update u guys if there are any problems..

damn, i just placed order for crucial from the website. 2 X 1gb cost ard usd 175 with shipments which certified for use with apple. using back my ori ram. i hope my gf dad's dell xps cld use kingston VR

so i remembered the code n went to other shops hoping to find d same code..

n i did found it at czone...unless d guy is BULLSHITTING me,than i hav to pray dat everything goes well...

pukarix,
chill bro, did not mean to make u worried. well i also use the same test method couple of time on kingstron ram, no problem watsoever.
btw i am back with the original ram. strange feels this original is much faster and no crashes. tested over nite. just b4 i change it last nite, while i was doing my work at my gf's hse, i put it on standby.. 3 x each time i open back, it reboot to login page instantly.

well dats wat u pay for getting d "cheap" RAMS.

pukarix,
so far i'm back with the original ram. have not shut down my notebook from home since morning n it works wonderfully.
anyway, perhaps this 'cheap' ram works on windows.

cld u provide the ram number that u bought the other day? appreciate if you can share. thx

do up date us alrite. looks like my transaction was failed for crucial ram. stupid tmnUt under their blocked list or perhaps my ip. got to ask tmnUt to varify it.
