Hi!

AMD Athlon II X4 / 2*2 DDR3 / Gigabyte 760G/SB710 / Asus GF210. USB sound, apple wireless keyboard, Atheros network. 10.6.8 retail installed via nawcom bootCD. Extra devices — only NEC PCI USB card. Using Graphics Enabler = yes — GeForce works ok — dual display, acceleration, games.

Everything works fine but only with maxmem=2048 option. Even 3072 gives me famous "out of 32b range" KPs. The most interesting thing — earlier system was stable without maxmem option, but later smth happened. I didn't install any hardware and I was on 10.6.8 initially. And even more — I've got almost the same PC, but it has RadeOn 4850 — no maxmem problems there.

I tried ANV kernel, amd_insn_patcher, disabled sleep, tested memory for whole night, mhdd, cpu stability test — no hardware faults at all.

Any ideas?

In /Extra folder I have only:
EvilAppleACPIPlatform.kext
EvilIOPCIFamily.kext
NullCPUPowerManagement.kext
TotallyFixStillWaiting.kext
fakesmc.kext

The only one that's suspicious for me is org.pqrs.driver.PCKeyboardHack — I use it to change keyboard layout with Caps Lock. But my other PC has this Extension too. VirtualBox is just installed — I already had problems before.
