ASRock reveals Socket AM3+ CPU details

ASRock reveals Socket AM3+ CPU details

According to ASRock, AM3+ CPUs may become unstable if plugged into an AM3 socket.

Motherboard maker ASRock has published a guide to AM3+ motherboards that not only lets slip a few details about AMD's new AM3+ socket, but also the CPUs that will fit in it.

One key concern, according to the guide, is the fact that a Socket AM3+ CPU fitted to a Socket AM3 motherboard ‘may not be stable enough to provide reliable computing.

It seems that while Socket AM3+ processors should be backwards compatible with any Socket AM3 motherboard that has the necessary BIOS update, the reality might not be that simple.

ASRock provides some details on the reasons for this, pointing out that the new CPUs and sockets support a 3.4MHz ‘Serial VID’ rather than the 400KHz frequency currently used. According to ASRock, this provides ‘a faster link between CPU and power controller,' so that AM3+ motherboards 'can support better power management and power saving.

The claims about the power-efficiency of the new socket and CPU are further reinforced by ASRock's use of a more efficient loadline design. However, this seems to be an ASRock-only technology, as the info site states that it's designed to not only ‘meet AMD’s requirements,', but also to provide an efficient power supply that will result in '11.8% better CPU power saving.

According to ASRock's guide, the maximum electrical current required for Socket AM3+ CPUs will rise to 145A, compared with the 110A of AM3 chips. The company also says that the 32 per cent rise in current will be partnered with a 22 per cent decrease in signal noise.

Whether or not the increase in amperage will be met with an increase in TDP (Thermal Design Power) isn’t clear – if the voltage of the CPU goes down, the power draw could remain the same, as Volts x Amps = Watts. However, it looks as though ASRock will be using a modified mounting clip called the CCR (Combo Cooler Retention Module) to improve the cooling of the CPU’s power chokes by 5.4oC. However, it looks as though ASRock merely cut the sides off a standard square retention bracket to create the CCR, though, which is backed up by the claims that ‘the CCR is backward compatible with the old AM3/AM2+ CPU cooler as well.

ASRock details nine different motherboards – both ATX and micro-ATX in size – that sport the new Socket AM3+ CPU socket. Curiously, they all use current-generation AMD 8-series chipsets and 7- and 8-series Southbridges, so the new AM3+ CPUs don't look as though they're going to be accompanied by a new range of chipsets.

Were you expecting a new AMD chipset to accompany AM3+, or are you just looking forward to getting hold of some new AMD kit? Let us know in the forums.

Which one is it?

I really don't mind if they drop backwards compatibility here as they are moving from CPU to APU and I think they will have to use a shoe horn to make it work. Fewer good products are better than lots of rubbish ones. However I do love backwards compatibility and I think that once the leap to APU has been made they should put it back in for the next lot of APUs.

Ouch! We were lead to believe this was a rank and file, top to bottom, new range of AMD CPU based on next generation of AMD chipsets.

Jesus Christ! could we get a definitive answer to what all this BS launch is actually going to be?

The fireworks have just fizzled out guys and gals!

I don't think any one ever did officially claim that they'd be backwards compatible. It's all been rumors spread by people on the internet.

Neither did I mention backward compatible.

By the time AMD get their oh so "mighty" bulldozer on the shelves, AMD devotees might have given up waiting and resigned to sandy bridge. Unless of course they're the same die hard fans waiting on Duke Nukem..

Oh andnot to forget intel will probably have Ivy Bridge out by then too..

Its like watching a Shetland Pony race against a Seasoned Race Horse!

Considering MSI have been value champs with both sockets AM2+ (with the K9A2 CF+Platinum) and AM3 (with the 770 C45), I'll believe this if they also bring out any AM3+ boards with existing chipsets.

Otherwise it's just a continuation of Asrock using old chipsets eg Crossfire from 2007 on a 2010-released board,and hopefully not a trend.

New generation of CPUs require a new generation of motherboards. Who would've thought

Why so sad?

AMD has been saying May/June for a long time afaik. You're on a tech news site, giving you news/rumours about new tech as they get it, its not officially from AMD. I'd wait for the official information personally.

I never understand the negativity from people, competition is good, new architecture is very interesting. It honestly feels like some people have jumped into bed with their chosen brand.

The 8 series chipset has many today's features built in. They could be improved with a revision but they already have SATA3, DDR3, USB3. I think the only thing left out is the PCI-E 3.0 but even that isn't due for the time being. 9-series chipset I think it isn't necessary maybe because the 8-series were already preconceived with Bulldozer in mind but a revision is always a good thing

As I and many that have been holding back to do a new build I'm more concerned with forward compatibility than backward compatibility to give my new build some longevity.

Sadly AM3+ isn't going to be long lived.

2012 is going to see bulldozer become an apu and I really doubt AM3+ will accommodate those apu's.

This concern about backward compatibility is a big mistake, Zambezi should be on a fresh start AM4 socket compatible with future bulldozer apus, Trinity and Komodo.

So... They're changing sockets like Intel... Good for them...

Exactly! AMD have always been good to us with backwards compatibility, but sometimes its simply not feasible. Intel have been selling us multiple sockets at the same time, so what's the issue here?

Also, all this is based on some marketing BS from a board partner. ASUS still say only a bios upgrade is needed. Of the two partners, I rather listen to ASUS.
