Sapphire Radeon HD 4650 HDMI 512MB Video Card Review
Elite Bastards posted a review on the Sapphire Radeon HD 4650 HDMI 512MB video card

Generally speaking, Sapphire have stuck with AMD's reference Radeon HD 4650 design here, employing the same small, single-slot cooling solution and utilising the standard 600MHz core and 700MHz memory clock speeds to boot.

Due to that small cooler, most of the memory modules on the board aren't actively cooled, although this isn't really a big deal for this level of card. As you'd expect, no external power is required for the Radeon HD 4650 HDMI, with the PCI Express slot capable of handling this board's requirements. The PCB is also bereft of any CrossFire inter-GPU connectors, thus limiting CrossFire connectivity to communication of data between GPUs over the PCI Express bus.

Crucial DDR3 1333 Memory on X58 Review
Bjorn3D takes a look at a set of Crucial DDR3 1333 Memory

Since the introduction of DDR3 memory a few years back, with the Core 2 Duo/Quad CPU's, along with the P35, X38, X48 , and the P45 chipsets, we, as users, have never really seen a significant increase in our memory bandwidth over using DDR2 memory. It wasn't until Intel introduced the Core i7 CPU's and the X58 chipset with their capability of handling not just Dual Channel, but Tri Channel capabilities, that we finally saw a significant bandwidth increase with our memory. But with these newer CPU's, Intel also has imposed a memory voltage limitation of 1.65 volts max to the memory modules. Intel states that going over this amount of voltage can and will damage your CPU because of the way the IMC (Integrated Memory Controller) handles the memory.

Crucial, a very well known memory manufacturer, has come up with a solution within Intel's low voltage limitation of the Core i7 CPU's. It's a three piece set of memory modules rated at 1.5 volts and 1333MHz with a timing of 9-10-10-20. Before you think that there's no way memory with such high latencies could ever perform, well, I'm here to tell you that these little beasties do.
