DDR2 1066 detected as DDR2 800, by bios.

Hey,
All DDR2 speeds above DDR2-800 (pc 6400) are overclock. DDR2-800 is a standard, the rest are not. Im not aware of too many systems/bios that will autodetect above DDR2-800 speeds (Im sure some exist).

Speeds above DDR2-800 will require a RAM voltage increase to ensure stability. If your system supports changing the RAM ratio, then there is a setting to adjust the voltage. Use it or go back to DDR2-800.

By manually changing the ratio you overclocked your RAM.

Many motherboards do not allow you to overclock above DDR2-800. So if you buy faster memory - your system may not even detect it or use it. This is not your case.

CPUz - yes thats what that means.

Your memory should function at 1066. It is not an overclock. You may need to adjust the voltage (at any speed), depending on the specs of the memory. It automatically sets itself to DDR2-800 for compatibility reasons. Changing the memory speed and timings according to CPU-Z is what you might want to do. Then test the memory for errors using memtest86+, because there have been bad chips/combinations.
Graphics interface is PCI-Express. You need to know if your motherboard supports 2.0 and if your card supports 2.0. Even if 1.1 is supported by your motherboard a 2.0 card should work anyway. We still can't saturate PCI-Express 1.1.

Ok first question have u upgraded your bios???

Thanks for all the reply's. : D

It doesn't look like I can change the timings manually in bios or at least I cant find it. (MSI K9A2 Platinum)

So, what I should do is set the memory ratio to 1:2.66 and adjust the memory voltage to ??

crap, i don't know how to post pictures, lol. never done it before. basically it's in the cell menu->advanced dram configuration (which is just above the fsb/memory ratio 1:2.66)
once in configuration menu select the first one and change it to both. then the timing appear and you can change them manually from auto to whatever you want.

if someone would be kind enough to let me know how to post pictures and not just internet links, ill post them here.

just make sure that the setting that you choose are the ones that your ram is rated for. other wise you could get bsod, if you are gonna overclock, it's goo to increase the voltage and to loosen the timings. it's more stable that way. i'd show you my timings, but i just rma'd my ram back to ocz. and all i got in is some old ddr667 ram which i use as spare.

My RAM runs on 2.2V by default, will that work fine or should I increase it even further ? And will the default timing settings be ok ? I'm not really into this.

Exactly what does this mean, do they still run at 800 ? O_o

What godless said. The 533mhz doubles for 1066, which is exactly what you want. I would leave it alone at this point, as raising the voltage any higher than 2.2v is looking for trouble as the temps will start to rise very fast.

you won't get a huge improvement. memory speed is not all that important in amd systems. most of the difference will be visible in some synthetic benchmarks, not in real usage.
