6GB/Triple Channel RAM not working on GA EX-58

[ferretrock]

Hey there,

My install's gone pretty well over the last few days (I've certainly become progressively nerdier doing it), but now I'm having a little trouble.

Pre-install I removed a stick of RAM (as requested in the install guide), but now on reinserting it I am scoring a kernel panic + shutdown on boot. I have tried using maxmem=6144 (and smaller amounts, 5100 and 4900), but only limiting it to 4096 works.

I am using the newest (ie. beta) drivers from Gigabyte F11o, and I haven't used any DSDT (I found only one DSDT for this MOBO and I didn't know what BIOS version it was for - consequently using it caused its own problems.

Other than this, most things seem to be running fine, I've got onboard sound, ethernet and firewire working and my Digi003 installed and working fine via Firewire (although something does make a weird high-pitch whine while using the 003, either the CPU or GFX card. Also, can't seem to get out of deep sleep (the keyboard has been switched off).

Anyway, I hope someone can help on the RAM issue, and if there are any clues on the others that would be awesome as well... it would be great to have it all working.

Thanks!

So you had it booting initially without the CD using 4GB or not?

When I only had 4GB in it booted fine (with the busratio=20 or 21 flag), once I put in the third 2GB stick it stopped working properly, I now have to flag maxmem=4096 in chameleon.

Booting (without the maxmem=4096 tag in chameleon) under verbose mode, it has the kernel panic at initialising firewire.
If I boot with the maxmem tag it doesn't hang and recognises both my firewire cards (internal and PCi).

Also, it should be said that all the RAM sticks are detected by the System Profiler and report as working.
Anyone..?

After doing a little more research, it would seem that the whiney noise has to do with speedstepping, but I can't work out how to switch it off with the new bios version..?

 

[ferretrock]

Just fixed the audio whine by setting a constant V-Core (1.30625V from memory), hope this is safe, I seem to remember turning off SpeedStep in the old BIOS as being the fix (but given that I upgraded by about a year's worth of BIOS's it's no longer there).

I fixed the RAM problem, -force64 must be flagged for some reason. Either way, it now works.
