Change Multi in AI SUite II?

[SpeedyVV]

I got the Rampage IV Formula. Is there a way to change the CPU Multi in Windows using AI Suite II or some other utility?

[lenehan]

My opinion to drop the idea of using AI SUite II for OC to avoid prolems/issue unpredictable, the best way to go to the bios and set it. Cheers.

To answer the question yes it is possible with one of the tools but I will second lenehan and advise against it as well!

You guys did not make the right assumption 😉

I just said change multi, not OC.

I already OCed using the BIOS, but sometimes I am not gaming and would like to lower the multi.

See I am an environmentally friendly person :rolleyes:

So what is this tool you talk of?

Most folks recommend against installing AI Suite period. Its been known to cause issues just having it installed, much less using it with overclocking/settings adjustments.

In the BIOS, enable speedstep/EIST, C1, and offset voltages; it will automatically throttle the CPU down to 12x multiplier as well as the voltage when not in use, and back up to your max multiplier when needed. No software control needed, and far more stable.

To further elaborate. By changing multi you are effectively overclocking. But I believe what you want is to actually control the throttling of the CPU multiplier while keeping the max multiplier at what you have set in bios. No that can't be done with ASUS Suite. The throttling of the CPU is happening automatically while it respects the Power Options (advanced section min/max multi) of the operating system. I have seen a third party tool that comes close to what you want (giving you far more power to the configuration and possibility of saving your own power profiles) in a sound engineering forum (EIST+Sleep states introduce DPC latency that professional audio equipment can't live with). You could try googling for it as I don't recall the name..

Ok, that is good info.

One of my uses for the workstation is Digital Audio (Guitar and stuff) and latency is a no no.

@jollywombat, i will enable speedstep/EIST, C1, and offset voltages as you suggest and just leave it at that, as from what you describe will give me what I am looking for.

Thanks for the help.

By keeping EIST and C-States on you will have dropouts at latencies <=4ms or so (depending on your audio interface. I use an RME Fireface UCX, RME hardware is which supposed to be one of the most solid around, both in hardware quality and driver stability/performance but even with only EIST on I get dropouts at anything below 4ms) . That's why in every professional audio forum those CPU features are suggested to be off (I dabble with keyboards and experimental music myself as a side project:)).

Check this thread out (apparently it's the one that mentions the utility I was talking about). The OP has several facts wrong (eg his claims on Turbo Boost) but the discussion is very thorough on the subject:
