New Platform: Gigabyte P35 DQ6 & Kingston KVR 1066 DDR3!

So then, it was time to check out it’s equivalent, Gigabyte P35 DQ6, but
board that runs DDR3 Memory, the new impending standard. Very fortunately, I got
a pair of Kingston KVR 1066D3N7K2/2G, a set of 2 x 1GB DDR3 Memory rated at
DDR3-1066MHz, 1.5v. Timings are CL7-7-7.

As you can see now, the Modules are based on Elpida Memory chipsets.

When the motherboard booted up, I was quite surprised to see that there was
no more 1:1 Ram:FSB Ratio, but the the minimum available is Ratio 2.4, meaning
if you run FSB at 400MHz, Memory will do 480MHz, or DDR3-960MHz. I found that
the 2.4 Ratio didn’t work so well with the Memory, but the 5:8 divider works
best. Also, the pair scaled quite nicely with voltage, but around 2.2v is the
sweet spot for it.

First, I took a look at how the pair does at CL6-6-6.

Alright, 624MHz with CL6-6-6.

Well actually, the Memory does CAS Latency 5 fine, but the RAS-to-CAS and RAS
Precharge much prefers to hover at the 7 setting. So I tested CL5-7-7.

Well now, you see that raising the middle two timings to 7 but lowering CL to
5, I could go higher than CL6-6-6, up to 664MHz.

Then time to test it out at it’s default timings – CL7-7-7.

736MHz!!! That’s DDR3-1472MHz.
