Hi,
I'm very confused (almost disapointed) with this memory.
My mb is ASUS P5W DH Deluxe and the processor is intel core duo E6700 @ 2.66.
I had 2 x 1 Gb Kingston KVR800D2N5/1G PC6400 @ 800 and the pc was really stable overclocked at 3.45 with 1:1
ratio and mem voltage 2.20, cpu vcore 1.46, fsb termination voltage 1.40, mch chipset voltage 1.55, ICH
chipset voltage auto.
I thought to buy Corsair TWIN2X2048-8500C5D to have fsb 1066.
1) I tried various combinations of timings and voltages and the pc was freezing, or windows crashing (blue screens with memory and cache messages). I understand from the forum that can't have 1:1 ration with 1066
but I also tried what corsair claims to work , that is 5-5-5-15 2T with 2,20 mem voltage @ 1066 and the pc was freezing at the vista boot screen. I raised the mem voltage without any luck. Note that even with the native speed 2,66 I couldn't boot.
2) This is my big question. Corsair claims that 5-5-5-18 @ 800 is verified for this memory. I tried several speeds (oc or not) with dram frequency from 266 to 1066 and I was luck to boot on windows, I get messages that various apps stop working and sometimes resets. I really dont understand why this memory can't work at least at 800 mhz.
With SPD or manual clock settings see no difference.
CPU Freq. 266 to 340
DRAM Freq (according to above)
PCI Exp. 100
PCI Clock Sync. Mode 33.33 Mhz
Memory Voltage 2.20 to 2.40
CPU Vcore voltage 1.40 to 1.48
FSB Termination voltage 1.40 (this is always stable)
MCH chipset voltage 1.55 (this is always stable)
ICH chipset voltage Auto
The truth is when I managed to boot with 1020, 1027, 1033 fsb and did some benvhmarks with everest I saw great mem performance. Orthos gives me errors very soon (3-10 min) with blend stress. The odd is when I do only cpu stress sometimes it can last 3h or more (manually stopped). But with ram stress in (2-5 min) I get errors.
Sorry for long length but tried to provide with some infos.
