Intel Atom N450 + DDR2 800?

chipset limitation of 667mhz, it will clock down
 
google it and it says that it will work with your Acer netbook. The only thing is it might clock it down to ddr2 667. I would just go with the ddr2 667 memory.
 
Get a stick of 800 with tight timings at 667. When you upgrade your machine you will be glad you have memory you can reuse. Choose your (online) supplier well: there shouldn't be a price difference worth talking about
 
The memory speed is a limitation of the integrated memory controller on the N450's processor die.

Intel® Atom™ Processor N450

You can use either. However, I agree with Completely Bonkers, in that, get the 800, especially, if it is around the same price point.
Better resale later, if needed.

Get the lowest latency you can afford.
And, definitely, google around, like TeXBill said, as, some memory is finicky with the different netbooks and will refuse to work or give errors.

If you netbook manufacturer has a forum... check there and see what others have used and not used.

Wow! Are manufacturers not aware of this? So many N450 netbooks come equipped with DDR2 800 memory! :twitch:
 
... because 800 sounds better. And also because 800 usually has tighter timings at 667. And it also costs the same OEM. So it isnt madness, it's the right thing to do.

BTW an Atom on ION chipset does run the memory at 800. But it make no practical difference. I have both. The Atom isnt fast enough to be memory starved.

Agreed

Yep the Atom processors can run ddr2 or ddr3 and @ 533, 667, 800, etc. depending on which Atom processor it is.

Is this even better than that DDR2 667 ram posted above?

Kingston HyperX 2GB 200-Pin DDR2 SO-DIMM DDR2 533 ...

Latency is low, but that is a result, I believe, of the lower bus speed.

So your answer, from me is, no... get the 677 or 800 mhz memory.
 
Someone over at the Overclock.net forums (yeah, I posted the same thread there too )
told me that the Acer Aspire 532h supports DDR2 800 memory.

When I googled it I found the same thing it supports either the 667 or the 800. So I would get the 800, the most it will do is down clock it to 667 speeds.

Well, I myself will take the thread you link to with a grain of salt.

They may well come with 800mhz memory; and, I believe that was addressed here.

The motherboard does not contain the memory controller... the Atom N450 processor does.
And, the N450 will run 800+ memory at 667.
If you have look at the link I posted you will realize this.

Quote from Intel: "Plus, Intel Atom processors include integrated graphics, video, and memory controllers built right into the die."

The different processors can use different memory.

The older Atom processors used a Southbridge chipset that controlled memory... newer ones don't.

Here are a couple of links that may help:

Happy 'Puting:)

Thanks. I guess I'll get the 667 with tighter timings then. :)
 
you can just use spdtool to flash the memory faster thats what i did to my netbook

Ooh! That sounds awesome! :twitch: So I can just hack my current ram to make it have tighter timings as if I could do it in BIOS on a high-end motherboard? :eek:

yes look up spdtool its free and on TPU just be VERY CAREFUL with it
 
It appears that my SPD is not flashable.

I guess I will have to get new ram anyway.
