Understanding ASUS AI Overclocking

GoLLuM4444 · Dec 23, 2004, 08:17 PM

Right,
I'm overclocking on my A8V and I'm soon to get an A8N-SLi which both have "Ai Overclocking".
When I overclock the CPU I increse the FSB (currently to 280) My ram is DDR500 (PC4000) so it should be able to cope with similar speed. The problem is this: When I increase the fsb this does not increse the operating frequency of the RAM (presumably the Ai technology is trying to allow me to overclock my CPU without being limited by my RAM) and this is not what i want. At 280 FSB my RAM operates at 230.

Confused? I am. There is no seperate BIOS setting (as far as I can see) that allows me to change the operating frequency of the RAM.

I could get some serious performance gain from higher clocked RAM but the stupid BIOS is holding me back. Anyone who can help me with this is possibly the most helpful person ever.

Thanks in advance,
GoLLuM

200mhz mem ratio or 1:1 setting? dont use the AI crap stuff. OC manualy also A64 dosent have FSB :P its called HTT, dont forget to lover the LTD multi when u pass 250HTT. im running 1:1 whit my BH5 rams on my S754 board eg 10x260HTT = 2600mhz cpu and 260mhz ( ddr520 ).

also check timeings on the ram.

Timings are defo right for these frequencies.

Where is the 200Mhz / 1:1 ratio changed?

I don't see it!

think i might have already answered this in another thread but it'll be to do with running half multi's. try running 11 and see what speed the ram runs at.

eya thats it dont run half multies

as mentioned use 11 and see.
