Latency clocks for DDR2 1066MHz

[PC Weenie]

I’m running two 1gig Kingston HyperX DDR2 1066MHz modules on the ASUS Maximus Formula board which auto. Clocks the RAM to 800MHz... From Kingston they only give, 5 - 5 - 5 - 15 at 2.2v as the clock... but I need the rest of the clocks for it to function a 1066 (5 - 5 - 5 - 15 - .?. -.?.-.?.-.?.)
Does anyone know the rest??

You don't need the rest of the clocks. What you need to do is set your memory divider so your memory runs at 1066 instead of 800. There will be an entry in your Bios for FSB:RAM ratio. It's actual name varies from maker to maker. Most Bios' will show you the resultant as you change this param..

The mobo will initially boot with the memory @800mhz, and my timings were 5-5-5-18 with the voltage at 1.8v. I set the timings to 5-5-5-15, voltage to 2.2, and change the memory frequency setting to 1066. Note that this setting will change depending on your FSB. Instead of listing it as 1:1, or 5:6, it shows you speeds instead, like 667 and 1066...

Will this is the BOIS layout;
Ai overclock tuner Set to manual
CPU Ratio setting Auto ?
FSB Frequency 333 (3GHz)
FSB Strap to North Bridge ?
DRAM Frequency Set to 1066
DRAM Command Rate Auto (choice between 1T and 2T)?
DRAM Timing Control Manual
And then comes the Latency clocks : 5
5
5
15
...
If you just set it to 1066 at 5 - 5 - 5 - 15 and put it at 2.2v it just trips??

CPU Ratio Setting: 9
FSB Strap to north bridge: mine is 400 for a 400 mhz FSB, was on auto until then
DRAM command Rate: 2T

When you say "it just trips" you mean what??

 

[PC Weenie]

Alright thanks for that but I’ve found a way... the ''FSB Frequency'' can be anything so I’ve set it to 366MHz (366 X 9 = 3294MHz for CPU) BUT the “FSB Strap to North Bridge” has to be set at 266 or auto (auto = 266) for pc to boot.

Do you think the FSB Strap to North Bridge will slow down the pc because it is only at 266??

And the PCIE Frequency is set to 100... Should it be more (Max is 180)??

Leave your PCIE Frequency at 100MHz, unless you know what you're doing. If you don't you can kill your vidcard.

I can get the rest of those memory settings if you need them. My board auto sets my kingston hyperx 1066, just like yours! It lists the other settings though they are on auto. How nice of it. If you really need em.

 

[PC Weenie]

The RAM Functions perfectly when the CPU FSB is over 333MHz (333 X 9 = 3 GHz)
So now I set the CPU FSB to 360MHz (3.24GHz) and the RAM is at 960... the next level is 1130MHz, do you think it's safe to clock HyperX 1066 to 1130??

Min mem is running at 1119 mhz (i think) and is stable with 5-5-5-15 2t timings, and 2.2v.
