One of the main update in LGA 1366 platform are the passage from the dual-channel memory to the three-channel, plus the passage of the memory controller directly in the processor.
However, the appearance of the third memory channel created an additional problems. First, it is necessary to buy memory in the three-channel complete sets. In the second place, six slots DIMM on the motherboard will occupy much more place.
Associate tested the processor core i 7-940 (2.93 GHz) with different memory channels configuration :
Here is the configuration used :
- Cpu : Intel Core 2 QX 9770 (344x8.5 = 2.93 GHz) and (400x8= 3.2 GHz) 12MB L2 Cache
- Chipset : X48
- Memory : DDR3 -1333 , 2x1 GB
- HDD : Seagate 7200.10 500 GB
- Video : Geforce GTX 260 (56/1998/1242 -Core/Memory/Shader)
and
- Cpu : Intel Core i7 940 2.93 ghz 8 MB L3 cache
- Chipset : X58
- Memory : DDR3 -1333 , 2x1 GB , 1GB , 3x1GB
- HDD : Seagate 7200.10 500 GB
- Video : Geforce GTX 260 (56/1998/1242 -Core/Memory/Shader)
Using Windows Vista ultimate SP1 and Forceware 177.98 for Vista
Increase after transfer from one memory channel to two is the most noticeable, moreover this concerns not only games. However, difference between the performance of dual and three channel is very small. In this case lynnfield processors with the dual-channel memory controller will be barely inferior to Bloomfield. However, with increase in the processor frequency the memory capacity will also grow, and the third channel open its potential.
Simultaneously associates tested the effectiveness of hyper-Threading. As is known, bloomfield processors can support to eight virtual thread, although physically they possess only four cores . Contemporary applications, hardly use the potential of four cores. In a number of tests, with hyper-Threading enabled the processor performance is reduced . However, in archiving, rendering and chess benchmark , hyper-Threading boost the performance .
