We've been talking about triple channel memory configurations a lot. This doesn't mean that 2 DIMMs wouldn't work in dual-channel configuration on a Core i7 platform, no Sir. So please understand that
you are not forced to a triple channel configuration. You can insert 2 sticks of memory as well, yet it would be configured in dual-channel mode.
The downside here is that you'll loose a third of your memory performance. However, since the memory isn't tied to the good old FSB anymore, a dual-channel memory configuration also reaps the fruits of the labor that is called the Core i7 processor memory controller.
We've been asked a couple of times if we where able to show you the differences, and surely we'll do so with a couple of benchmarks. Here we go:
So again we look at Sandra. We see 27.47 GB/sec peak bandwidth for the G.Skill memory setup in triple channel (3 modules) at 1600 MHz 9:9:9:24 timings.
Sandra is a synthetic benchmark, therefore it wioll also show the biggest difference. And once we have setup the memory exactly the same, now yet with two DIMMs inserted in the PC (Dual-Channel) we see a hefty drop in overall bandwidth performance.
We fire up a real-world application, WinRAR and test again and see there's a noticeable difference between the configuration at tripe and dual-channel setup.
There will be situations where the difference will be much smaller. We transcode a video again from a 1080P high definition VC-1 formatted source file towards the Windows WMV9 format. Now honestly, the difference is nearly to small to call. And that amazed me for sure.
The GPU bound fear again then .. we do see a slight drop in performance. But you'll agree with me, dual-channel configuration with a Core i7 processor certainly doesn't blow.
It surprised me as much as likely it did for you guys. But you can measure the bandwidth difference really, yet that doesn't mean it'll drag the overall pc performance down. If you like to save a nickel or two in the upgrade processes. It wouldn't be a shame really to go for dual-channel and if you already have DDR3 memory .. simply use that.
The reality is that you'll still have excellent performance in a dual-channel memory configuration ... yet to take it up that extra notch, I'd go straight away to triple channel.
G.Skill Sniper 8GB CL7 DDR3 memory review G.Skill designed another 8GB low voltage DDR3 kit (2x 4GB) that can be set at 1600 MHz yet still run a CAS latency of 7. And that is truly interesting because the denser the ICs get, the higher latency typically gets.
G.Skill 2x4GB CL7 1600 MHz Trident DDR3 review We feel that more memory is rather important, and in that trend memory manufacturers have started to increase the density of DIMM modules. Where 1 and 2GB DIMM modules have been the standard, we now see very good progress in 4 GB DIMM modules. Today we\'ll do things a little different, G.Skill designed a 8GB low voltage DDR3 kit (2x 4GB) that can be set at 1600 MHz yet still run a CAS latency of 7. And that is truly interesting because the denser the ICs get, the higher latency typically gets.
G.Skill Flare DDR3 2000 MHZ C7 AMD kit review We test and review the G.Skill Flare DDR3 2000 MHZ C7 AMD kit. These kits are optimized for AMD platforms preferably with the new six-core X6 processors, and in specific some ASUS motherboards. The kit we'll be testing today obviously comes from that series and is a 2,000MHz CL7-9-7-24 1.65V 4GB (2GBx2) DDR3 kit with its latest Flare heatsinks.
G.Skill Phoenix PRO 120GB SSD review The SSD tested today once again is the Phoenix series from G.Skill. After we tested their 100GB Phoenix SSD (which received a very positive review) G.Skill instantly requested if we would like to review the 120GB PRO model. Both drives pretty much are the same thing, same controller ... The 100GB Phoenix uses Samsung memory though but the trick is that there is 20GB extra volume space available on the new 120GB Pro (compared to the 100GB model) for nearly the same price. A new Firmware for the SandForce 1200 based controller that is inside this 120GB model simply reserves less NAND flash memory for its data-compression scheme. As a result the overall write performance could be a tiny bit slower, but only a few percent as best. It however will give you 20 GB more space to play around with at the same price. And since price per GB is everything in the land of SSDs -- this certainly is a significant for any vendor and for you as an end-user.
