ASUS L1N64-SLI boots with AMD Opteron 2218 and standard DDR2-667 memory

AMD insider and occasional DailyTech writer Dave Graham posted images of an AMD Opteron 2218 processor running on an ASUS L1N64-SLI motherboard. This is intriguing as the ASUS L1N64-SLI is a motherboard designed for AMD’s Quad FX enthusiast platform. The motherboard BIOS detects the processor correctly and functions properly.

It also appears that the system is using standard DDR2-667 MHz memory instead of registered ECC memory typically required by Socket F Opteron-based motherboards. Although it would seem memory compatibility problems would arise, Graham has images of the system passing Windows Vista’s memory diagnostic tool without error.

With compatibility with AMD’s Opteron 2200-series processors, the ASUS L1N64-SLI may be the holy grail of dual-socket socket-F motherboards. Although the motherboard is pricey, the compatibility with AMD Opteron 2200-series processors opens up AMD’s Quad-FX platform to more budget-conscious buyers as the dual-core AMD Opteron 2200-series lineup starts with the 1.8 GHz Opteron 2210. The Opteron 2210 is also priced around $200 USD per processor, which is $150 lower than the cheapest Athlon 64 FX-70 processor.

The ability to use standard DDR2 memory with AMD Opteron processors may also appeal to workstation users that have resisted AMD Opteron systems due to registered ECC memory requirements. A quick search on Newegg shows the cheapest DDR2-667 modules costing around $70 while the equivalent DDR2-667 ECC registered module costs $130.

Another interesting item to note is the screenshot of the Mainboard tab in CPU-Z. The ASUS L1N64-SLI is based around NVIDIA’s nForce 680a SLI MCP but it is detected as the nForce 570 SLI, revision A1.

What this means is that FX is really just a rebadged Opteron. It also means that for single moduel/channel usage, the opteron should be just fine with regular DDR2...

Good for customers, sad for AMD...

I think it's interesting how AMD is, how may I put it, operating a bit more desperately now (I don't know if this is the best word thou), just like Intel was doing when AMD had the performance advantage (with all that HT and EE stuff and how they were so hurried to ship Prescott it ended up consuming more power than Northwood).

It's worth noting, however, that the Opterons continue to proceed through extra validation for their roles as "SERVER" products.

Also, this has nothing to do with product announcements or anything else. It was simply a field test of viability. As it stands, I heartily dislike this L1N64-SLI WS board. I much prefer Tyan's excellent S2915 (n6650W) workstation board due to it's design, compliance with SSI spec, and widespread availability.

cheers,

Tyan and supermicro boards have always been lacking complete PCI-X compatibility. I've had two experiences where a RAID controller had to be run at reduced speed or was incompatible because of the AMD HT1000 bridge used on many serverworks platforms.

Correction, AMD-based Tyan and Supermicro boards.

How is that sad for AMD? People have known that A64s are identical to Opterons (and vice versa)for a looong time now... like since the launch of the product family.

In my opinion, it is deceptive to market the same product as two different SKUs with supposedly different capabilities. The customer that pays more than they should have for the imaginary extra capability eventually feels deceived once the lie is revealed.

Also, remember, not everyone knows, and not everyone can be sure. For example, when I bought my Althlons years ago, I had to buy the special MP version that supported SMP. Even though there were rumors at the time that the SMP and non-SMP SKUs were actually the same product, I couldn't really risk "trying it out" in case it damaged the processors, MB, etc.

Huh? What are you talking about? AMD's Opterons are exactly the same as AMD's K8s, Intel's Xeons are exactly the same as its Pentiums/Core 2s, it's always been this way. Sometimes we see special SKUs (like the Gallatins and, more recently, Tulsa) but for the most part the server parts are rebadged (and repackaged) desktop parts (or the other way around, in the case of the K8, since AMD's focus is on the server side).

Mustn't forget however that usually server chips are the highest quality bins you can get. Not that it particularly matters but its still a point.

Well, how can you know that the core is not tweaked in some way(or something internally enabled on it) to be able to work in SMP enviroment ?
(i.e. multiple-bus in case of Athlon MP or asymetrically-loaded bus in case of Xeon DP/MP's)

I believe the SMP Opterons have extra HT-links enabled that 1-way Opterons and Athlons do not. This is what prevents people from running cheap, 1-way K8s in SMP motherboards. In that case, it's not that AMD added something extra to the "better" CPUs, but rather they disabled something in the cheaper ones. However, I'm not terribly surprised to see that Opterons can run non-ECC memory, as I'm sure AMD has designed the IMC to handle both memory types so they could use their CPUs in any product line. ECC sacrifices speed for added stability, and really most memory is very stable for the average user. ECC memory just adds extra assurance for critical computing environments.

There's less of a speed sacrifice than you think (usually on order of 3-5% at a given clock speed). Again, the Opterons benefit more from lower latency than anything else. So, having a CAS 4 DDR2-667 ECC/Reg. part (none exist) would be more beneficial than a CAS 5 part. *shrug*

Opteron 2000 series parts have 2 HT links (processor to processor and processor to NB/SB). Opteron 8000 series parts have 3 links. The price adjustment has to do with the ability to maintain signal integrity across ALL links. It's not a penalty as such. Have you seen how much Xeon 7000 series parts are selling for? *grin* For n-way builds, I'm more than delighted to spend the extra $$$ to ensure that I/O capabilities aren't bogged down by MCH translations, etc. Point to Point is a very, very efficient topology to use.

cheers,

Dave

I still have my asus am266 SMP board working with 2 athlon XP 1900+ processors. Those palominos XPs(?) still work fine eventhought they were officially not workinng in SMP mode

Not really. The Sledgehammer and Clawhammer cores differed in that the Sledgehammer had a dual channel memory controller where the Clawhammer did not.

Clawhammer also had the dual-channel memory controller, and all the extra HT links, they were just disabled because of the packaging (it doesn't matter what you throw into the die if there are no pins for it). AMD didn't redesign the core just to get rid of the extra memory channel or the extra HT links, it just disabled them afterwards.

It means that they were not able to tweak the core a bit to work with 2 modules unbuffered as X2's do.
It is nice they were not forced to do it since Opteron on itself works with single unbuffered module/channel.

I also makes the whole QuadFX platform just a PR stunt which some people thought it was not until this information.

You know I gave them a bit of credit as the platform (thanks to the ASUS uber-board) is actually pretty usable and makes sense.

However this means they actually did NOTHING except for asking ASUS to make exceptional board for them.

Sad is the fact that they
a) have to resort to such tactics
b) intentionally misled the public
c) the only thing the actually can take credit for is comomming up with the idea

This IS sad for a company claiming leadership in the industry.

Not really a fact.
AMD did not misguided anyone, claiming quad is here 'pumped' 2x2. And it ended up favouring their theory.
Although performance were more server oriented, the product was limited to a higher bidget due to the current line pricing/positioning in the market.
And what is wrong with making this opteron compactible. If it fits, right price category range it could be a 'tweak' the gamers, and low pocketed 'rollers' will surely go for.
I think this is just a timed speculation, so it would grab attention before the next product hits the shelves. And it better be fast and good, because Intel is really shining at the moment.
So no fooling around AMD is just there fot the fans.
We love AMD.

Since the memory controller is integrated into the processor, it's unlikely that this will be an option.
