On paper that upgrade should be amazing. With each core being faster I don't see why the upgraded Xeon shouldn't be better in every regard in your machine.I upgraded the Mac two x5690 3.46ghz. Before I had the 5645. I do still have the original memory at home. I can test it with the original 1333 MHz memory to see if there is a difference.
I think that if you upgrade the RAM to 1333MHz you will probably see an additional gain in single threaded performance as well as a gain over the original multithreaded speed.Okay. Maybe will need to upgrade the rams to 1333. What do you think of the temp. Is that good or is it high
Yeah, if memory speeds are mixed all the RAM will run at the speed of the slowest module and reduce overall performance. The good news though is some of your RAM is already 1333 so you won't have to upgrade all of your RAM sticks.Wow guys. I never paid attention to this but it was shocking. My Mac got replaced but the Apple Store here in LA and they mix match my memory. I never bother to the check the memory today. But in my Mac I have 1333 and 1066 together. Before the upgrade it register as 1066. It suck. I will have to order memory or is it best to buy from eBay or owc.
The rear CPU always reads hotter than the one in front. Right now my rear CPU is running 12⁰ F hotter than the one in front.Also I just notice that one of my CPU is running hot. I may have to redo the thermal paste tomorrow. It is about 8 degree C. higher than the cpu that is located by the front. The cpu that feels that is hot is the one toward the back. Right now it is reading Diode are 52, 43, 50, 40 Thanks for your comments guys. I really appreciate it.
