990FXA-GD65 Vs. 990FXA-GD80
« on: 11-September-12, 16:30:24 »

Hello to every-one  8-))

I'm hoping someone can tell the difference between the "990FXA-GD65" and the "990FXA-GD80" in regards to performance and durability.

I've seen some people say that the GD65's Northbridge gets hot and that the GD80's does not, Would a hot Northbridge be a problem ?

I may do some light OC'ing.

Basically i would like to know which one would be better  :confused2:
What i will be doing: Game Programing, Gaming, Some rendering and Video conversion.

I'm getting the FX-8120 BTW.

Many thanks.

Advantages:
Dr Mos:In order to provide customers stable and high quality products, starting from P45 series mainboards, MSI is leading the industry to introduce the world's most advanced power supply component, DrMOS (Driver-MOSFET), which integrates Driver IC, Top MOSFET and Bottom MOSFET into one chip. Except for its outstanding performance in power saving, DrMOS possesses switch frequency which is 400% faster than traditional MOSFET and has great improvement in stabilizing power supply and voltage control. Even under heavy loading and overclocking conditions, DrMOS can still provide the most stable and efficient power supply and quality.

More PCI Lanes

Sideport Memory(Useful you buy a vga that support hybrid SLI or use onboard vga):  is used by ati tech. as dedicated buffer memory for integrated
graphics,located on the motherboard.It is usually higher clocked ddr2 or ddr3 memory
 which is faster than usual system memory providing better performance for integrated graphics.
 Motherboards claim for an increased >10% performance by using sideport memory.

3 way sli

APS:Active Phase Switching, APS, technology is an intelligent design that helps to save energy on MSI’s mainboards. The underlying idea is to switch off the power supply as soon as no electricity is needed, and when the system needs more resources again, APS will automatically adjust electricity supply accordingly. APS will automatically detect your processor’s loading at any given time and save energy accordingly. This is only possible by means of a very advanced power controlling technology. Other than software-based solutions, APS technology stands out from MSI's own research. The specially developed IC chip can operate automatically depending on the demands of the power supply, which is to reduce the total power usage.

Generally speaking with MSI boards, the first part of the model indicates the chipset ie 990fxa or z77 and the last set the tier. ie gd 65 / gd 80
Generally the higher the number at the end the higher end the motherboard.

Ooh, i didn't find that page while googling.

Any idea on how much power the Dr-MOS and APS saves ?

So i could expect better performance from the GD80 ?

So the GD80 is overally a better board ?

In this case If money isn't an issue, I would go with the GD80 especially if you are planning on overclocking.

If you hang out for awhile, a few people who frequent this forum have a few of these and can give you a first hand account.

Any idea on how much power the Dr-MOS and APS saves ?

if your computer idles or at low load more then 25% of the time in those instances the power used by your system at that time will be about 30-50% lower then if it has standard mosfets and no APS (active phase switching)!

it would reduce the power at those times to the RAM and CPU to save power while its not being used for anything intensive! if your computer is only used for gaming only and CPU intensive tasks it will not make much differance as the DRmos will be at its lowest eficency (5-10% less power used) and APS will be pretty much inactive (0-1% less power at most for briefe periods)!

DRmos though does run alot cooler under identical loads then traditional mosfets due to its layout of its all in one design!
