Hi, everyone. I'm having problems trying to get two 512MB RAM modules running at DDR400 on the Asus K8N motherboard (s754, pretty much budget version of K8N-E).
One RAM stick is a Mushkin DDR400 value stick with default timings of 2.5-3-3-8 and another stick is an AMPO (I know, I know) with default timings of 2.5-3-3-7 at DDR333 and 3.0-3-3-8 at DDR400.
Now, the thing is, both sticks run fine at DDR400 by themselves on the mobo, but when coupled, their speed is throttled down to either DDR333 or even DDR266 depending on what combination of the 3 available slots that I use (4 combos in total, since DIMM0&1 must be occupied when multiple sticks are used).
Neither RAM is damaged since they worked fine by themselves, and also because they worked perfectly well in my old mobo (MSI K8T Neo-FSR).
I realize that the mobo probably just doesn't like the combination of these two sticks, but I've tried using a Kingston stick (identical values as AMPO stick) which also doesn't work.
I've upgraded my BIOS and all drivers to their latest version, no help, and manual setting of RAM speed values are not working. So now I have 3 options available to me:
1) Buy another stick, preferrably one identical to one of my sticks. However, I don't know if it will fix the problem as it may be a board problem.
2)Buy a new motherboard. I would hate to do this, as I really like this board's sound quality (no buzzing or hissing whatsoever from EMI) and also I don't want to take out everything again. I was hoping that this board could last until I upgraded to a new processor.
3) Compensate for the reduced speed by overclocking the HTT and tweaking multipliers and such. Basically, some serious overclocking that I'm not sure my computer can handle.
What option is IYO best, or does anyone have another suggestion? Thanks in advance. Also, on a side note, FSB values are inaccurate with CPU-Z (201 instead of 200 MHz, and HTT becomes 804 instead of 800 MHz) and RAM speed is noted at 160 MHz, not 166.6 MHz. Both may not be real problems though, and voltages are relatively stable.
Specs:
Athlon 64 2800+ Newcastle
Leadtek 6600GT AGP
Thermaltake 430W (the one constantly on sale on Newegg.com)
3 fans, nice temps always under 55C in total system, processor, vid card, hdd
