Also ich hab auch die GBHZ drin, 4 GB, und habe folgende Einstellungen (aus dem Asus Forum):
I had some problems getting four sticks of memory to work with this board. I though that I would post the results of what I did to make it work.Senario:I originally installed the board with an E6600 and only 2Gb of memory (2x1Gb OCZ 6400 CL5) with no problems. I overclocked the CPU to 3GHz (9x333) with a 1:1 memory ratio (memory would run at 666, below the rated 800). Had absolutely no problems with the board. Prime95 stable for > 8 hours.Installed two more sticks of memory (same type) and the board would not post. Pressing reset would cause the board to post but at default CPU speeds. Manually setting the FSB back to 266 (default) and the memory speed to 800 would allow me to boot into windows, but computer would randomly lock-up. Using Memtest86+ v1.65 showed memory errors. So I pulled all the memory out and tested each individual module for at least one complete run. (I manually specified the mem timings and voltage in the bios, for my modules they were 5,5,5,12, 2.0v @ 800Mhz) No errors when using a single module, or two in dual channel, but three or four modules would always produce memory errors. I was using the following settings in the BIOS: (v307)
Mem V = 2.0
CPU Vcore = auto
FSB Ter = auto
MCH V = auto
ICH = auto
CPU Freq = 266
DRAM Freq = 800
CAS = 5RAS
Prechange = 5
RAS/CAS Delay = 5
RAS active = 12
Read dealy = auto
Hyper Path3 = Auto
DRAM throttleing = Auto
I suspected a power/voltage problem. works fine with less load, but increase the load and one of the voltages were dropping to far.
I didn't know what the FSB Term voltage was for or what was a safe value. A quick search on google turned up several references.
http://www.lostcircuits.com/motherboard/asus_p5ad2e/8.shtmlIntel spec for the termination buffers is .85-1.65v, but this is also the supply for the bus voltage which should not be more than 1.29v. Also, this voltage should be ~50% of the DRAM voltage (for me that would equal ~1v) I manually changed the FSB term voltage to 1.3v (safe max) and re-ran my memtest. no problems. I then changed CPU Freq back to 333 and memory to 666 and re-ran mem test. no problems. more testing should that I could safely set the FSB voltage to 1.2v with no stablity problmes.
Conclusion: The auto voltage settings do not work properly with this board. This board has a know problem with overvolting the CPU, and that is probably not the only area that this bios needs work in.
Not trusting the auto settings, this is how my bios is set now.
Mem V = 2.0
CPU Vcore = 1.225 (lowest selectable in the bios, results in 1.28 Vcore)
FSB Ter = 1.2
MCH V = 1.5
ICH = 1.05
CPU Freq = 333
DRAM Freq = 666
CAS = 5
RAS Prechange = 5
RAS/CAS Delay = 5
RAS active = 12
Read dealy = 7T (recommended on XtremeSystems forum)
Hyper Path3 = Disabled (could not find any good info about what is does, I don't trust it)DRAM throttleing = Auto
Notes on CPU Vcore:When set to auto and CPU freq at default of 266 Vcore would result in 1.38. Increasing the FSB would automatically increase Vcore (don't remember the number). The Core2 chips operate on a voltage range, the max specifed by intel is 1.35 (no OC) most chips should be albe to opoerate at lower voltages than 1.35. Mine runs at 1.28 @ 3Ghz on stock air cooling. Load temps @ 50/51 as reported by auss probe (~ 6-8 cooler with Core Temp)
Sorry for the long post.

Und habe alles am Intel Sata haengen, 2xRaid 0, 2 Raptor und 2 Seagate, der MARVELL brachte ueberhaupt keinen Speed, da hatte ich zuerst 1x Raid 0 dran, war langsamer wie eine Platte. Haeng wenns geht alles an den Intel und installiere Intel Matrix Raid Accelerator.
