Ram really should be bus speed or higher.. Processor expects a given Front Side Bus speed and while it *may* downclock to a slower speed to match the RAM bad things may happen too (as in it'll not run at all - like three beeps at boot bad).
You can afford a Mac but not $50 bux for 8gb of the right memory? That's pretty epic fail there.

That is complete and utter nonsense. There is no FSB that is a thing of the past. There is also no equivalent and absolutely no clock speed that has to adjust.Ram really should be bus speed or higher..

The IMC runs at the clock speed the RAM modules tell it to run in the SPD settings. Benchmarks also show no discernable difference in speed between 1066 and 1333. I have also never heard of a RAM module that was too slow and didn't run for that reason. DDR3 is DDR3 there is only a too fast and some voltages may be unsupported but no too slow.

Benchmarks have shown that there is not much of a difference.
No it doesn't exist ANYMORE.Front Side Bus: Another name for the system bus.
System Bus: The bus that connects the CPU to main memory on the motherboard. I/O buses, which connect the CPU with the systems other components, branch off of the system bus.
The system bus is also called the frontside bus, memory bus, local bus, or host bus.
Yeah, don't exist. Right.
No it doesn't exist ANYMORE.
Core 2 Duo had an FSB no Core iX of any generation does and no AMD CPU since Athlon 64. The FSB died out on those chips just like the back side bus did so long ago.
It was a bus that used to connect the Memory Controller and all the other stuff on the external chipset die to the CPU (cores) on the CPU DIE. Yes it was called system bus by some it still doesn't exist anymore.
Today all the stuff it used to connect is on the CPU DIE and in case of Sandy Bridge connected at the same speed the LLC (aka L3) Cache is connected. With 384GB/s theoretical bandwidth compared to which the FSB well just doesn't compare.
Here is a list with all Intel/AMD CPUs that still had an FSB. The most recent CPU is the Core 2 but that was the end of the FSB.

"It's worth noting, especially if you use older DDR3 memory, that you need to keep the VCCIO/VCCSA and memory voltage within 0.5V of each other. This follows on from the same rule set by Nehalem and Lynnfield, but given that the whole Sandy Bridge die is now 32nm and operates at a lower ~1.15V voltage, mixing this with older 1.65V+ DIMMs puts it on the fringes of acceptable long-term reliability"
And this has what to do with benchmarks?
Suppose you explain why RAM has a frequency rating if "it's all the same and makes no difference"
I'll even help : http://en.wikipedia.org/wiki/DDR3_SDRAM
Oops. According to that chart those 1067 modules don't have the memory timing or CAS latency that a Sandy Bridge processor is designed for. Snap.
The ram will work fine. You will NOT notice a dip in performance at all. Benchmarks have shown that there is not much of a difference.
The only thing JamesCorman has been wrong about is that the IMC is not connected by the QPI either but he never unlike you presented it as a fact.
Benchmarks to show that there is little to no difference. Synthetic Memory benchmarks show a difference but they have no significance. In any significant real world benchmark the difference between 1066 and 1333 is maybe 1 %. Performance difference is usually to small to be measured accurately without averaging many many benchmarks.
That whole nonsensical ranting about the Voltage difference also fails add anything to the topic. 1.65V+ RAM maybe a topic on older desktop over clocking rigs. In the mobile space it is a none issue because there is only 1.5V or lower and for a 1066 module you'd be hard pressed to find one with too high voltage.
JamesCorman was not "very wrong" at all. They only reason you might perceive him as depicting himself as superior can be that you are bitter.
Accept when you are wrong and research your answers better or leave the task to others. Those posts of yours seem to serve no purpose but to confuse the op.
Also try to understand what the topic is. Upgrading mobile ram is something that require absolutely no knowledge about memory timings and desktop like over-clocking stuff.
I am actually, very confused!?!?!
Thank you for your constructive reply.
So does this mean then, that I can actually use my 1067 modules in my new machine?
