Äh die Seite kennste bestimmt schon oder ?

Hat aber noch ne bessere wo auch ein ausführlicher Test dabei war. Hättest das mir mal vor 3 Wochen gesagt
Hier noch ein Fundstück zum testen gilt auch für x48...
Some info you really do need to know and follow.
X38 and X48 DDR2 boards clock 2GB modules not as well as P35 boards.
The SPD on these modules is 5-5-5-15, you do NOT have to manually set any timings.
I strongly suggest if you are overclocking a quad core Intel CPU you lower your expectations, the added load the CPU places on the chipset has a profound effect on how well the FlexII modules overclock.
If you are seeing issues we will ask you to test with the 1000MHZ option to start, this with NO OVER CLOCKING on the CPU at all, we will then ask you to push up the FSB on the CPU so that the memory runs at 1150, we may ask you to drop the CPU multiplier while doing this.
These modules do NOT need massive voltage, 1000MHZ on a good P35 board will usually be stable with 1.8V, 1100MHZ with around 1.9>2.0V and 1150 with 2.05>2.1V
You may have to dramatically increase the voltage to the NB chipset on your board, you need to be aware the chipset is going to get HOT so make sure it has active cooling...
FlexII 1150 is a very high speed binned kit, it may be over the limit for some boards due to the load placed on the memory controller by the density of the modules and the speed we are trying to run. You need to be aware you may have to spend time tuning your board...we will do our best to write guides but we can NOT spoon feed you timings...every board acts differently, so there is going to be some work by you also.
Remember Intel boards have an option for tRD (Read Delay) some call it Transaction booster, some performance level. You may have to lower this value to get stable operation. In my initial tests i am finding relaxed levels of tRD do help.
A quick guide to tRD using FlexII 1150 starting tests at 1000MHZ ram speed.
CPU at stock FSB either 1067 or 1333 CPU's.
tRD of 5 6 7 8 9 10 11 etc are all in theory possible when using the 1000MHZ option for the ram, 5 and 6 are quite aggressive so if you see issues try 7 and higher.
If you are overclocking the CPU to 400/1600FSB you need to choose the 1.25 option for the ram sometimes shown as 667 for 1067CPU's or 832MHZ for 1333fsb cpu's, this will give 1000MHZ on the ram with the CPU at 1600FSB. With this setting you can no longer use tRD of 5 you have to set 6 or higher This is most important as the board may boot but it will be totally unstable.
Asus may set tRD at 5 by AUTO so you have to be aware you will have to manually relax this timing.
1000MHZ is a good place to start testing, from here you can lower the CPU multiplier and then push the FSB up so increasing ram speed also.
