I am very familiar with computer technology including hardware-and performance tuning.
I did put the wink after my comment-I was deliberately saying something ridiculous. Sorry, my dry sense of humor is often lost in forums. something was reset due to hardware changed), but not the memory clock difference. If there is actually a significant improvement, it's from something else (e.g. I am sure the bottleneck is not there, and you should not able to see any difference. However, for opening mail / browsing the web. So, unless you are doing something that really memory bandwidth intensive. My understand is that 25% is more like the capacity (bandwidth) increment, but not really speed increment. Therefore, if you put some data in, they actually come out more or less at the same time.Įven though this is not the actual time required to finish the process, but a simple and good enough way to compare the time required to finish the same job.Īs you can see, the difference is about 2.8%, nothing close to 25%. Because the RAM either run at 1066MHz CL7, or 1333MHz CL9.
However, it's more like capable to do more work at the same time, but not able to finish the work faster. The RAM run at 1333 can process more data per second. Especailly browsing the web or opening mail is not memory bandwidth intensive task, but more network speed dependent. That speed improvement has nothing to do from 1066 to 1333. You mean the system work much faster now because you have more RAM, but not the RAM speed from 1066 to 1333. The beauty of the MP is sleep mode-not warming the house unless we are using them. I have a 3,1 at home, my wife uses it to remote into her office to work from home-so its income producing property! IIRC, it has a few cornfield type rows of 1 or 2 gig sticks with their heat sinks, just roasting away. It was a great reassurance and good to stress the ram while its within the 30 day return policy, or whatever. I appreciate the practical experience people are sharing here-saved me a lot of money by not going with that premium vendor where the ram had the heat sink and temp sensor on it, but no need for that memory tester ran for a long time-I had it set for 10 cycles, but after an hour and it was still on first cycle, I set it to 1 cycle, which still looks like it ran for 4 hours-overnite. So, my thinking is that 1333 is 22.5 % faster and hotter to the same degree-but glad to hear it is of no concern regardless. Therefore: faster cycling generates more heat. The transition period is tiny, but it exists. So, when they are conducting, no heat because no resistance, when non-conducting, no heat because no current. My understanding of logic devices is that they mostly generate heat during the transition between conducting and non-conducting-number of transitions direct correlation with clock speed. I have an ssd boot drive now that is plugged into the regular sata drive bays using a physical adapter-maybe going pcie would not be a signifiant speed boost. Don't want to pay the apple tax unless its required. I see OWC has some stuff along these lines, but wondering if there are less expensive options that work just as well.
#BEST RAM FOR MAC PRO 2010 32GB INSTALL#
If I install an ssd pcie card, format with guid fs and so forth, can it be bootable? Are there special apple requirements for such a card. Apologies if I missed the same.Īnother quick one: I am reading threads here and elsewhere regarding pcie ssd. I did a few forum searches and was not able to find any discussion of the relative merits of brands of ecc 1333 ram, so a new thread. I think this stuff is simply your bread and butter 1333 ECC ram harvested from retired servers, or NOS stuff laying around. I see on amazon, ram that is quite a bit less expensive, but appears to lack a heat sink and do doubt no temp sensor. In any case, to keep a reliable machine, just how compatible does the ram have to be? Anybody have favorite sources of good ram at good prices? I have purchased from one outfit who claims their ram is better because it has the metal heatsinks and a mac proprietary temperature sensor. I currently have 12 gig with 3 4 gig sticks. So, its currently a single quad core with 4 memory slots. Got a hex core on order and looking to up the ram. Based on some great threads here, I decided to give my mac pro 2010 a mid-life upgrade.
