Gigabyte GA-EG31MF-S2 (G31 Chipset)

Previous Next
1:50 AM - 10/10/2008 by Patrick Schmid and Achim Roos

The second board in this little roundup comes from Gigabyte and is called the GA-EG31MF-S2. Unlike the Foxconn product, it offers four DDR2 memory slots, although you are still limited to the maximum supported memory capacity of 4 GB for the G31 chipset. It does not come with all solid capacitors, which doesn’t have to be a disadvantage. Again we only found a D-SUB15 analog output for displays, which we think is not the best choice—any modern graphics solution should at least have a digital DVI output.

Features

The board comes with the same basic features as its competitor, but Gigabyte adds some more components, such as a FireWire/400 controller. A second port can be activated once you purchase an adapter cable and attach it to the additional FireWire header on the board. The same applies to four more USB 2.0 ports; four are ready to be used. Chipset components are kept cool using heat sinks with no moving parts, which is good for keeping both system noise and power consumption low. You get one UltraATA/100 channel and a floppy port as well as two 32-bit PCI slots. Like Foxconn, Gigabyte provides one x16 and one x1 PCI Express slot for upgrades.

Power and Performance

All mainstream and better Gigabyte boards are equipped with voltage regulators that Gigabyte states are fully VRM 11.1-compliant. The layout on the GA-EG31MF-S2 is based on four phases and solid capacitors, which provides better voltage stability at high current levels. This is necessary for power-hungry processors such as 3+ GHz quad core models. However, we found that the Gigabyte board required considerably more idle power than the Foxconn board, despite similar components and despite the fact that Gigabyte’s Dynamic Energy Saver (DES) technology was activated. DES allows the system to switch off voltage regulator phases when they’re not required.

 Gigabyte decreases the idle voltage to 1.120 V.Voltage for full speed (2.53 GHz) was 1.15 V.

Nice article. I'd like to see the team now take this budget system and tweak it into a gaming machine. New power supply, overclock it, 4870 GPU and see what this budget platform can do when pushed. Compare it to a stock clock E8600, X48 motherboard, 8 GB of RAM and a 4870. Although low power systems may be the rage right now, when i turn a 1,500w electric heater on in the bathroom when i take a shower in the morning it's not a huge concern for me if one mobo is 31w at idle and the other is 38w.

You don't leave your heater on 24/7 in the bathroom - 8 watts here 8 watts there, it adds up (if you keep your PC on all the time)

Or you can get a 4X50E with a 740g or 780g, that is cheaper and equal energy efficient and has all the futures like HDMI, 3D performance.

alex57340141 :
As far as turning this machine into a mean, green gaming machine, I would suggest an e2140-bsel pin modded to 1333 fsb, a hitachi 500GB sataII drive-4w/8.3 idle/max, and a hd 4670 videocard-no external power plug required. This would make a very potent rig. I know this because that's what I have on the foxconn board used in this article One last thing, with case, p/w supply and 2Gb ram the total cost (including shipping) was less than $300.



Sounds like a nice build!

Yes, from the silentpcreview article, it seems like 740g or 780g could be a better choice.

Ya most people would do just fine with an amd system. But TOM's got new free computers, car's, spaceships from INTEL and NVIDA so nowadays tom's are a EPIC bias.

Now that we have desktop systems that approach laptop-level power requirements, I would say that in a year that we should have some really good choices on the market for low-power-consumption desktops.

That is... if the world still exists as we know it in a year...

warezme you are a retard.

Where I work there are currently 120 desktops between 4 levels. Each desktop is on 24/7. If i can save 10 watts on each of those desktops im saving thousands of dollars per year. Get it now? Just because you are a gaming scrub with no clue doesnt mean that all technology should appeal to you.

Calm down folks. Warezme, there are people interested in these setups, they just need to run internets and word. While the components are indeed weak it is not lame to write about them, esp for business perspective.

Skythra, no need to call someone retard for expressing an opinion which I agree with by the way. These desktops are really nerfed and a laptop would fit nicely as prices have dropped a lot.

Carry on now.

Warezme:

Get serious. This machine has ample power for the standard office productivity applications, which probably represents 90% of the use of computers in the world, including in the corporate sector. The difference between these builds and a stacked $2000 machine is almost totally invisible to such users. Indeed, the only people that would really notice the difference are the people writing check to the utility companies.

I like AMD but I am no AMD fan boy. The only AMD X2 chips that come close to E7200 is 6000+ and 6400+ and they use a lot more power. In addition, if for some reason, I need more power than 2.53 GHz I can just OC to 3.0 GHz without voltage increase. Find an X2 that can achieve 3.8 GHz with reasonable voltage.

At work I had a choice between an HP laptop or desktop, I took the laptop for work at home, but If i did not go on road, a g31/e7200 setup would demolish my t7300 laptop with 2gig ram on a 800 bus with ddr2 667.
I dont play a single game on this laptop but i do watch a movie here and there...and its fine...so the g31 would be more than enough....

I just have one more comment regarding recent toms articles....how is a 1,500$ system a budget system...I dont have the money to buy that when i'm gaming once in a blue moon.

I built a system for about 400$ and comes close to some of these things....an e2160 chip at 2.6ghz, 2 gig ram, asus p35 board, and asus 8600gt, an 80g sata drive for the os and an older sata 200g for some tunes and pics....and i bought a cm 690 case with cm5500 extreme power ps....the only thing in their i wish i could change at the mobo(settings dont allow for good overclock) and the power supply is loud...but that system is close to what i can afford....spending 1500$ to me is not budget, not when your putting a quad core and other stuff, a budget system should be that, on a budget, shopping for deals....etc...oh and if ya wanna save power...shut the mofo down....if your woried on how much a small system will cost on electricity you should have bought the system....just like the idiots that buy a dodge ram v8 and have never put more than a few pieces of wood in it and cant afford the 150$ gas bill each week.....

GMA 3100 is NOT based on GMA 3000 - this is totally different. It is based on the older GMA 950 (pretty much 100% identical in fact).

I would like to see a amd comparison, such as the AMD Athlon 4850e 2.3GHz paired with a FoxConn A7GM-S. This is a $135 pairing as opposed to the Intel reviewed which is $175.

Warezme, i don't think you have a very good understanding of how some people use cmoputers. Not everyone uses their comps for gaming and not everyone can use a laptop to meet their needs. I personally run a X2 4450e on a 780g chipset to house my raid array. This setup runs quieter, cooler and draws less power than my previous P4 setup.

Just because you cannot see a use for this technology does not mean the rest of the world cannot. Some of us care about how much power we use.

Why not just get a laptop??? You would also save power with its LCD screen versus a separate monitor.

Isn't this what many people requiring a non-gaming machine are doing these days??
