Aeneon DDR2-1066MHz and DDR3-1333MHz 2GB KitsDDR2: CL3 and CL4 overclocking
The default voltage for this pair of memory is 1.8V.
We tried various Vdimm values and noticed that 1.95V to 2.0V is the sweet spot for this pair of memory. For all our overclocking tests of the Aeneon DDR2 kit, we have kept the memory to 2.0V.
Interestingly, setting the memory to anything around 2.2V to 2.3V, which is still considered 'rather acceptable' to more enthusiastic overclockers, would result in system instability. The system refuses to POST when 2.3V or more Vdimm is fed to the Aeneon pair.
A 70mm fan was placed on top of the northbridge and memory sticks to help cool the components during overclocking.
Let us start overclocking with CL3 values.
With 3-3-3- timings, this pair was able to give 334MHz (668MHz DDR). Not a fantastic result, but it isn't that bad either. However, 3-4-3- and 3-4-4- did not give us any increase in clock at all.
Moving on to CL4, we started off with 4-3-3- timings.
We weren't quite able to hit 400MHz on 4-3-3-, stopping at 350MHz (750MHz DDR).
4-4-4- timings gave us 462MHz (924MHz DDR).
We ended up with the same clock of 462MHz (924MHz DDR) at 4-4-3-. Knocking down the RAS Precharge value did not have any impact on memory speed.
