A8N32-SLI runs the regular nForce4 SLI x16 chipset and not the server version (nForce 4 Pro).

Anyway, just to point something out regarding the Asus A8R32-MVP Deluxe (it came across for sale on the forums and hence I did some research on it), it CAN overclock and isn't that horrible. Just look at some reviews:

So, unless your 1st hand experience proves otherwise...

isnt that still fairly cheap? why hesitate?

A8N32 is worth 25€, A8N-SLI Premium a bit less. The pricey 939 stuff are CPUs.

..

fair enough.

Any idea would this work?

Nope, that's DDR2

It HAS to be HYS72D256320HBR-5-C or it very likely won't work.

Well, I just stuck a HP branded 512MB PC2100 REG ECC module (Infineon HYB25D256400BT-7 chips) in an ASUS A8N-E motherboard and it booted just fine.

that's 512mbs but, that's good news on the ECC front!

Ho all,
Sorry if I am bringing back this thread.
I' m trying to set up a machine with a A8n-sli premium , bios 1303, and 8gigs, but I have problems.
At first the system won't boot, it emitted some beeps, one long amd two short.
I know that this code points to a vga problem, but all the vga I used (even pci) was ok.
So I decided to change RAM.
I have ddr400, ddr333, ddr500, ECC (obviously), but no results.

Then I decided to remove the cpu (opteron 175), and turn on the power, no beeps.
The I installed the cpu WITHOUT Cooler, I know it seems insane but I did it, for five seconds, no boot, no beeps.
I installed again the cooler and it booted!!!

Now it seems that it boots ONLY if I use a single Dimm in slot-3 (blue), if I put a single dimm in a different slot or if I put another one, it mess up again.
Even a 2gb ecc dimm is ok in slot-3.

Another thing, I am not able to find the "memory hole" optional in bios, there is no suck thing, maybe there is something related I should activate/deactivate?

Thanks in advance.

Try another CPU, in case the Opteron 175s memory controller is bad or broken.
Look for cooling paste in the socket and on the CPU pins, clean if you find any.
I would also try updating the BIOS to the lastest version (if 1303 isnt the lastest) if you find enough stability to do so.

The Opteron 175 (running in a late Asus board) should accept just about any DDR memory you can find if everything is working correctly.

#2 DDR1 2GB modules (at least all of the ones I've seen) incorporate piggy-backed memory modules! So they are essentially two 1GB sticks combined.

Really? My Kingston KVR 2GB module was just a simple double sided one.

At the moment I'm working on another round of CPU benchmarks. The plan is to test (relatively) new software on old CPUs - so windows 7 x64 and plenty of RAM (at least 4GB) is a must have. Using four 1GB DDR modules to get 4GB @ socket 939 is not what I want, so I decided to try two 2GB ECC Reg DDR sticks from my s940 system. So far it seems to be working just fine on Asus A8N-E and A64 3700+ (San Diego).

These are 36-chip DDR266 CL2.5 modules. Running stable at 400 MHz CL2.5-3-3-6 1T at default voltage, not bad. 😀 Maybe CL2 would be also possible but I don't want to push it too much.


Later I'll try other A64 based on different cores which may not be compatible - Winchester and NewCastle. And after that maybe even socket 754... who knows this turns out. 🤣 Chance of success is much smaller I guess. Either way I'll report my findings.

Tried more 939 chips... so far results are :

San Diego 939 (3700+) = working
Winchester 939 (3200+) = working
NewCastle 939 (3500+) = board doesn't POST
ClawHammer 939 (3500+) = board doesn't POST

That's a solid setup. 😀 You even managed 1T CR.

Thanks.
Posted it up for Havli to see.
Been a lurker for a while. Nice site. Lots of old school info.
I know a few people here.
Hope to contribute a little.
Thanks for having me. 😀

Nice score Mr.Scott, running socket 939 K8 over 3GHz is not easy... and with 8GB DDR 433 MHz - impressive. Although 1.66V is maybe too much.

So far it seems s939 Opterons and A64(X2) based on the same core are almost guaranteed to support ECC Reg. DDR. Later I'll try socket 754, but chance of success is minimal I think.

Let's not confuse ECC modules with ECC Registered modules.

A lot of boards will do ECC modules, but the Asus A8N series was pretty unique in that it is able to handle ECC Registered modules (they have two rows of 8 on each side).
