Unfortunately, one of the sticks in the first pair of modules that I received didn't work. Our contact at Kingston quickly took care of this and we had a replacement set the next day.
Let's back up a bit though, and do a quick walkthrough of the install. Both sticks are in the white sockets so we can get dual channel working.
A quick shot from the other side of the motherboard.
Now first we need to take a peek at things and see how they're running.
Here's the main screen of CPU-Z after bootup.
What we would get if we used the SPD setting in the BIOS. The RAM is programmed as PC2-5300 with 5-5-5-15 timings for compatibility reasons.
Changing the speed and timings to run at 800MHz as the spec sheets suggest (plus changing the voltage to 2.0)
Now, before we installed the Dual Channel kit, I was running a stick of Kingston Value RAM (KVR533D2/1GR). I ran PCMark05 Pro which we received
from Futuremark, and below is the base score that was achieved from the entire test. The Memory score is 4269.
After the install, I ran the benchmark again, and the Memory score had shot up to 4834.
A look at the scores side by side. The system is the same as the first testing, but there has been a little overclocking of the video card (as seen in the 7900GS review) which is why we're focusing only on the Memory scores.
I also took the time to run Sandra 07 Memory bandwidth test.
Test 1 was done at the specified settings (800MHz, 5-5-5-15)
Next, I tested at an overclocked setting of 800MHz 4-4-4-12.
