A79A-S Software, BIOS, and Accessories

Previous Next
2:10 AM - 11/13/2008 by Thomas Soderstrom

Like all recent AMD chipset products, the A79A-S supports AMD’s overclocking utility. Foxconn also includes its Fox One utility for viewing and changing various BIOS settings from within Windows. Fox One has several optional skins, so we tried to show a different skin for each menu.

Fox One is reasonably comprehensive and works fairly well, but we prefer to adjust our BIOS settings from within the BIOS GUI to reduce the likelihood of a crash affecting our Windows installation.

BIOS

Foxconn’s “Northbridge Voltage Control” is completely different from Asus’, and we believe it’s because Foxconn is referring to the actual 790FX northbridge rather than the processor’s on-die memory controller.

BIOS Frequency and Voltage settings (for overclocking)
CPU Reference Clock 190 - 400 MHz (1 MHz)
Clock Multiplier Adjustment Yes
DRAM Ratio All CPU On-Die Memory Controller Ratios
PCIe Clock 90 - 250MHz (1 MHz)
HT Link Multiplier 1x - 13x CPU Reference Clock
CPU Vcore Stock - +0.60 Volts (0.024 Volts)
CPU PLL Voltage 2.30 - 3.25 Volts ( 0.06 V)
HT Link Voltage 1.776 - 2.640 Volts (0.048 Volts)
Northbridge Voltage 1.68 - 2.355 Volts (0.045 Volts)
DRAM Voltag e 1.80 - 2.20 - 2.70 Volts (0.05, 0.10 Volts)
CAS Latency Range (DDR2-1066)
tCAS: 3-7; tRCD: 5-12; tRP: 5-12; tRAS: 15-30

Foxconn’s BIOS is fairly limited by performance motherboard standards, yet still contains AMD’s Advanced Clock Calibration settings, which can help tremendously in overclocking a Phenom processor.

As usual for Foxconn, CPU core voltage is adjusted in steps, requiring tuners to do the math and calculate the actual target voltage. A little more confusing, however, are Foxconn’s CPU FID and DID controls, which we had to experiment with in order to find the actual ratios we sought.

Accessories

Accessories
Documentation & Software Motherboard Manual
Motherboard Driver DVD
Hardware 6x SATA Data Cable
1x 80-conductor Ultra ATA cable
1x Floppy Cable
1x Port Breakout Plate (2x USB, 1x IEEE-1394)
1x I/O Panel Shield
6x 4-pin to SATA power adapter

Foxconn keeps Windows XP users in mind by supplying a floppy cable in the A79A-S installation kit, since floppies are handy for installing RAID drivers. The six SATA power adapters probably aren’t needed, however, since power supplies for its market already have several SATA drive connectors.

"Also notice the removable BIOS IC, a feature that makes bad-flash recovery as easy as plugging in a replacement."
I don't know about you guys, but I haven't had a flash going wrong since a P2B board from the stoneage

Call it paranoia from a guy who changes BIOSs on an almost daily-basis on one board or another (me, not Thomas, though he does his fair share of updating, too).

Perhaps it's just the luxury of gigabyte's dual bios that makes me not care for removable ic's but I just don't see the relevance. Nobody has an eprom writer for those chips at home anyway, and with prices of many motherboards closing in on what a new chip would cost it's only truely useful for the expensive boards - and if an amd board is expensive, then it's targetted at the wrong people.

Thanks for the review. As you have stated, only way that AMD can compete with INTEL is to provide better clock speeds on their chips. Intel has shot forward with giant improvements and AMD has been stuck on the side lines. Their 45nm chips are still not on the market and Intel is already making moves to switch to 32nm.

Sadly, this is going to be tough hill to climb for AMD to become competitive again. I wish them luck though, the consumer is always the winner when corporations compete :)

Im sorry, but this is rubbish:

Ive got a phenom x4 9950 placed on a ASUS m3a32 mvp deluxe motherboard.

With stock voltage and stock cooling ive cranked it up to 3.2ghz and it runs perfectly stable. (this was done by only adjusting the multiplier)

A friend of mine have the same setup as me but an aftermarket cooler (noctua nh-u12p) and hes overclocked it up to 3.4ghz, again running stable.

On Overclocking forums i read about people cranking this CPU up to 3.6ghz on air (noctua nh-u12p) without any wizardry.

This test is flawed and im very dissapointed about tomshardware and what i feel is an effortless test of this setup.

Im an Intel guy myself but at least im honest about intels oponents, and in this case the review should end up with AMD being amazing value for money and that the future is a bit (not alot) brighter for AMD.

You realize that the Q6600 can also be overclocked to 3.6GHz on air as well without much difficulty? Both processors are at the same price point. The only difference is that the 9950 is AMD's top end chip and the Q6600 is a entry level quad core from Intel...

im aware of that yes, but the problem here is tomshardware not the q6600... why? they didnt get it over 3.12ghz, which frankly is pathetic.

and the 9950 is cheaper then the q6600 its cheaper then about every intel processor out there (even the dual cores such as e8400 etc).

Im not saying it is a better processor then what intel has lined up, what im saying is that it is amazing value for money. and much better at overclocking then tomshardware managed to get out of it thats all :D

That thing has the third pcie slot in the very last spot making dualslot graphics impossible. And that in turns makes the motherboard useless as it no longer features anything intel can't do with it's x38 or p45 and a faster cpu

Oh my God, you guys went with a Jetway over a DFI board!



Article announced end of September. Submission deadline mid-October. DFI wasn't interested or otherwise didn't respond. DFI's inaction is unfortunate.

If that’s the case one could argue that you guys write for manufacturers and not your readers.

I'm also surprised to see DFI excluded, especially since you used DFI in some Intel test some time ago. I would definitely say DFI gives good value for money these days.

Another point: hasn't AMD quite clearly said it won't be able to compete with Intel high end CPU:s and hence is aiming at giving better value for money in the "mid-priced value market"? Yes I'm even quoting some words of the article, but my point is that because of this it's quite unnecessary to go on about "too little to cure AMD’s ills". Of course the AMD64 era was astonishing since AMD did the unthinkable with resources as big as Intel's pocket-money. To believe though that AMD would be able to over perform time after another is wishful thinking. It's already proven that even with a superior product AMD won't be able to get good enough sales. So if you're really interested in finding the cause of the illness, it's not to be found solely inside AMD's headquarters. Without their inventions I doubt we would have seen the light of anything in the series of Intel Core CPU:s.

There are several scenarios where I at the moment without hesitation would prefer Intel. If I did more rendering the Core i7 is a clear winner. Besides that even your Core i7 test showed that the 700/750 scales well when running more AMD/ATi graphic cards.

To choose AMD over Intel isn't stupid, it's just a question of individual computing routines, in some AMD gives great value even beyond the 4-core scenario you mention in the article. When looking through benchmarks it's necessary to evaluate it's impact on your personal computing. In many cases you get a overall figure like "this platform is XX % faster", but the reality is that might be much less because the benchmarks are irrelevant to my computing.

A long rant - and it's not a rant anyway - to convey a simple message:
- Intel has a great line up of CPU:s at the moment
- The above doesn't mean AMD "is ill" or disappointing

/A formed (with constant relapses!) narrow minded overclocker who found out that there's a lot of more fun computing stuff to do

The 9950 is NOT cheaper than the Q6600 -

9950 = $185 http://www.newegg.com/Product/Prod [...] 6819103291

Q6600 = $180 (OEM) http://www.newegg.com/Product/Prod [...] 6819115018

or $190 (Boxed) http://www.newegg.com/Product/Prod [...] 6819115017

Either way, a five dollar difference is insignificant - they're about the same price.

From where I'm standing it's the other way around really. It's the manufacturers not included that don't care about the readers. Those who sent in boards are those who care about us readers - and dfi appearently isn't one of them at this point. You can't blame toms for that really.

In my opinion, it's just really difficult for AMD to continue to compete effectively against Intel at this rate. Even while Intel is slashing their sales outlook, they are still well funded without having to rely on external investments and loans. Also, their new processor lines based on i7 are very promising with early positive performance reviews. Heck, their current Core 2 architecture isn't even close to their end of useful life cycle. Meanwhile, AMD HAS NOT produced any new performance-competitive CPU SKUs (even price-performance advantage has been losing ground), and they have been LOSING desktop/laptop market share. The only positive product line left for them is in the graphics market, and they actually have gained market share with 48XX series. I think they should focus most if not all of their talents and funding in their graphics technology, and phase out their processor line. Also, I know it's good to have a competitor to Intel, but at what cost to the AMD emplyees and investors? Would you rather have AMD go bankrupt and end up selling their assets to ______ (fill in the blank) or stay in business and use everything they know to continue to improve their strong points?

I'd rather they merge their cpu division with cray or via than surrender to intel. Like any other enthusiast I am using an intel processor, but if they don't have any competition in 3 years time, then nobody will use intel, cause they'd stop developing - they'd become like microsoft's windows division - you can marvel at what they archieved in the past, but can't really appreaciate their current efforts. I don't want to hate intel, but if amd dies its inevitable.
