[danuputra]

Guys i have a problem here.. i have 2 MacBook Pro's 1 for me & 1 for my brother..

MacBook Pro A :

Proc : Intel Dual Core 2,33 Ghz
HD : Hitachi 120 GB
Memory : 3 GB DDR2 SDRAM 667 Mhz (Dari Apple-nya)
VGA : ATI Radeon x1600
Display : 17"

MacBook Pro B :

Proc : Intel Dual Core 2,33 Ghz
HD : Hitachi 120 GB
Memory : 2 GB DDR2 SDRAM 667 Mhz (Dari Apple-nya)
VGA : ATI Radeon x1600
Display : 15,4"


Then i'm testing it with Xbench.. :

any advice guys ? what happen to mac book pro A ? should i claim to the store ? cause i have apple care on mac book pro A.. thx before guys.. sory for my bad english.. thx..

 

[nomar383]

First of all, Apple will never take Xbench as legitimate testing as far as I know lol. And how many times did you run it? Were any other programs running? Xbench can be fickle sometimes

 

[danuputra]

i have been testing with geekbench too.. and the score for A is 1345 & the score for B is 2930.. any suggestion for the benchmark tools ?

 

[danuputra]

and i felt a little lagging in MacBook Pro A.. like showing widget for example..

 

[nomar383]

Get rid of everything you don't need. Backup the rest, and try a full reinstall. If that doesn't help, then reinstall without ANY of your own apps. If it is STILL running slow, take it to an Apple store and have them check it out. Mention that is running slow, even in factory condition. You don't need to mention Xbench as your testing app though lol, they probably won't care

 

[johngardiner]

That's definitely strange. Though there should be a small discrepency leaning towards the 17 inch, it shouldn't be as large as what you posted. But as nomar said Apple won't base service off of a benchmark score, but if you take it to them and tell them it has been acting irregularly slow they might take a look at it for you.

 

[amusiccale]

Another vote for a format and reinstall--something is not right, but it's hard to prove hardware problems from benchmarking alone. Backup, start over, and see what happens.

And that Geekbench score is shockingly low on the first one("A")--my 2.2 is usually very close to 3000 and it's a 15.4"

 

[danuputra]

i've already format & re install the MacBook.. but it is still the same (..

With none of your own apps on it? If so, then definitely take it in to have it checked out

It looks like system A has 3GB memory - If these on different size sticks then your memory may not run in dual channel mode and that could impact performance. Just a guess but easy to test.

 

[bplein]

I just ran xbench on a 2.33 with 3GB of RAM (1GB+2GB) and it runs twice as fast as his System A.

Take the memory out of both systems, and swap them. Then retest. I am thinkiing that maybe you have slow or bad RAM in one system. See if the problem follows the RAM.

 

[danuputra]

guys do you know how to check our RAM are Dual Channel or not on mac ? do you know where the info is ? thx..

 

[bplein]

Dual channel doesn't make it twice as fast (I have non-dual channel running in my 17", it runs twice as fast as your slow one).

Do the memory swap test, moving memory between machines, and re-running the benchmark. That will test for bad or slow RAM.

 

[danuputra]

Problem solves guys.. the problem was the memory brand it doesn't same.. one "samsung" and the other one "lydic".. now i am running 1 gb samsung + 2 gb samsung memories.. and the result with xbench for the processor is 145.67.. problem solve.. thx for your support guys... sorry for my bad english

 

[danuputra]

Noooo... it happen again ( it coming to 60.12 again with xbench.. what happen ? i have already changing the memories.. (
