    ASUS C90s Memory Speed Issue (?)

    Perhaps this is noobish, but I was wondering...

    I recently installed a Kingston 3GB DDR2 memory set, listed at 667MHz, PC2-5300 (1x2GB, 1x1GB, same series, same specs). However, when I booted the system after installation, all I could get it to report was "PC-4300 Dual-Channel Asymmetric".

    Performance is still vastly increased over my old Corsair ValueRAM 2x1GB setup, but I'm wondering if there's a reason it's not reporting a higher speed.

    Thanks in advance for any feedback. On a completely unrelated note, has anyone found a seller that actually has the GDDR3 GFX cards in stock?

    Er... yes, it is. I'm getting a report of 4300, when I installed 5300. Any ideas?

    C90s automatically defaults 667 ram to 533 due to the fsb of the processor being 1066 so 533*2 (dual density) = 1066. The ram will be fully activated during overclock mode when the fsb is increased even though the ram is still technically not at full 667*2 speed.

    At least that's what I think the explanation is but the fact iss till that all ram above 533 has to be clocked down to 533. I think I gave the right explanation but I know someone out there can help explain it better.

    Sorry if my earlier post ddin't make sense, what I was trying to say was that since the c90 clocks everything down to 533mhz, thats what its reported as. (Its hard to type long sentences on an ipod.) :)

    YUp because it can't reach 333 FSB, it downlocks everything to 533

    With a bit of haxoring I got my e6600 to boot 333 default, however, thats about as far as it got since I didn't want to make it permanent ;)

    Interesting. With as hot as it runs already, I'm betting it added more than a bit of heat load to the actual modules, right?
