I'm still struggling with this stupid netbook to get it running at its peak. It is an Asus 1201 HA. It came with 1 gb of pc2-800 6400, and i swapped it out for a 2 gb stick of pc2-800 6400. The front side bus is supposed to be 533 for this pc and it shows that in the rated slot on cpu z, but the actual bus speed is only 133. From the way I understand it shouldn't it be at 266 since it is ddr2? I can't find any way to set it in the bios, but it should recognize the speeds automaticly shouldn't it?

cpuz shows wrong speed

So wait. You have DDR2 running at 266MHz (133*2). The FSB is at 533. CPU-Z says the RAM is running at 133MHz? Sorry I'm just slightly confused by the way you've phrased it 
If it does say 133MHz then that's fine because the RAM itself runs at that but it's dual channel so effectivly *2 gets the overall speed (hopefully this is right, don't attack me if it's not)

So wait... your running your RAM at 266MHz right? That would make sense for the 133Mhz Bus speed but what does the Core speed refer to? RAM speed? CPU speed?
This sounds more like CPU stuff than RAM sutff :s

Dual channel does not double the frequency of anything.If it does say 133MHz then that's fine because the RAM itself runs at that but it's dual channel so effectivly *2 gets the overall speed (hopefully this is right, don't attack me if it's not
OP: Post up a screenshot of the CPU tab and the Memory tab for clarification.

133mhz quad pumped = 533FSB
133mhz X2 = 266mhz DDR2
your fine.
133mhz X2 = 266mhz DDR2
your fine.

either have the pic hosted at photobucket.com or the like then post the URL or use the IMG URL. another way is to, when you post here in the forums. if using quick reply, hit "go advanced", from there scroll down to attach files then click on manage attachments and the rest should need no explanation.
*edit*
now even though the fsb is 133mhz, the chipset will use a diveder to achieve the higher ram speed.

in the case of the pic i linked to of my Atom 230 box. you notice the divider listed under ram speed? that is what is making it run at 266 mhz. now in your case you should see it saying 400mhz, now this is the SDR rate. Since it is DDR, it is effectively running at DDR2-800.

I don't mean double the frequency but the speed it runs at is twice the bus speed. I don't know much about RAM, maybe I should leave this one to you all =P

DDR stands for Double Data Rate. Even with one stick, it will run twice the FSB.

ok well crash course... single channel is 64bit wide, dual is 128bit, each channel adds another 64bit. that is right now its 64bit wide per channel, that doesnt mean it wond change in the future. the SDR (single data rate) will always be shown in CPUZ. simply because that is the true speed, DDR uses that speed say 133mhz. it inserts data at the top half of the cycle and then the bottom half, that is how we get DDR. that is also why when you see/read most ram reviews they say effective Ram speed, ie DDR2-800, even though it really runs 400mhz.

That's the same as DDR 1 PC2100 back in 2002 and 2003.

that would be right for 945GM and the US15 chipsets. though that netbook he has is a ION netbook, NV's chipset can handle higher speed ram. after all the 6x0/7x0 have unlinked ram ratios. i havnet use a ION platform so i dont know if its the same. i would at least expect the NV chipset to do DDR2-800, i mean look at the price of some of the ION's.

didnt notice more then one, opps.. yea your going to be limited to either DDR2-533 or DDR2-667 for ram speed. the GMA500 video is on the US15 PCH/Chipset.
