RAM problem

Hello.

I tried to put four 512 Mb RAM modules taken from a V240 into a V210, and when booting I got the following error:

ERROR: CPU0 DIMM 0 SPD reports DIMM has unsupported SPD revision

System configuration failed, powering off

1.- What does SPD stand for?

2.- Can anyone tell me how to solve this problem? Could it be solved by upgrading de PROM firmware?

Any help would be appreciated, thank you very much

Let's see:

You installed RAM, this is memory, using SPD +memory for a google search results in numerous hits

Take the definition, which is the first hit.

http://searchsmb.techtarget.com/sDefinition/0,,sid44_gci533524,00.html

To answer the second question, the information you gave is insuficient, because it lacks the part # of the memory modules and the OBP revision (of the V210).

Thanks for you answer Michael.

I searched RAM + SPC at google, and all I could find were forums were people had problems with the SPC but not the technical definition I was looking for.

I'm sorry for the lack of information. What do you mean by "the part # of the memory modules"?

The OBP revision is: OBP 4.8.2 2003/03/27, so it's quite old. Could it be the problem?

Again, thank you very much

Try a Google search for serial presence detect

http://www.google.com/search?hl=en&q=serial+presence+detect&btnG=Google +Search

(that is what the "SPD" acronym means)

I think that Michael was expecting you to be using Sun memory modules, not 3rd party stuff.

Each DIMM will have a bar-code label that includes the Sun part number.

The usual issue is:

Old archaic OBP versions do not work with better SPD modules.

You must upfdate the OBP if you hope to have them function.

You should not mix SPD valued RAM in a system, so you may find

that you need to remove the original modules.Try them. See what happens.

I'm using Sun memory modules. As I said, we had a new V240 unused & wanted to switch the processors and memory to an older V210 which is very importan for our work.

The label in the memory modules sais the following: 512 DDR PC2100 CL20 ECC.

I didn't mix SPD valued RAM (assuming that all the modules in the V240 had the same SPD revision). I just removed the old RAM modules & put the new ones.

So, to sum up, my problem would be that my version of the OBP does not work with this new modules, right?

Last questions: If I upgrade OBP, do I have tu upgrade ALOM? How can I check my ALOM version without rebooting the machine?

Thanks a lot

Hi,Check the hardware compliance their is some compatibility differences between V210 and V240. look at www.sun.com/documentation section server V240 compliance

Hello,So, to sum up, my problem would be that my version of the OBP does not work with this new modules, right?Maybe your memory modules don't work with later/current OBP versions.Without the Sun part no. for the modules we can only guess...Michael

Hi Michael. Thanks again for your answer.How can I check the sun part no. of the modules?Sorry for the inconvenience, I'm new with Sun hardware stuff.

Hello,

How can I check the sun part no. of the modules?

I assume that these are Sun modules, other modules void the 1 year warranty or a service contract.

Open the V210 and review the barcode sticker on the modules. Look for a number starting with 370 (e.g. 370-6202 is a 512MB module).

The above mentioned module has SPD 1.0 which requires OBP >=4.11 Version 4.

Review the Full Components List for supported modules (link at the end of this post).

Updating the OBP might fix the problem with the new modules, but the old modules won't work anymore in this system.

But as rukbat mentioned all installed memory modules require the same SPD version. You can't mix modules with different SPD versions.

Links to OBP updates for the V210 can be found on the following page

Thank you very much Michael.

Turns out my memory modules are 3706202, so they have SPD1.0 and require an OBP update. I have two last questions:

1.- Every OBP version higher than 4.11 will work with SPD 1.0?

2.- Does ALOM require to be updated if I update OBP? I can't tell my ALOM version because in order to do that I have to reboot the computer which I cannot unless strictly necessary because it is always being used. So, I'll change my question: Do early versions of ALOM have problems with later versions of OBP?

I've seen restrictions like: ALOM 1.5 requires OBP 4.11 or higher, but if I update OBP, will it cause any trouble to ALOM?

Again, thank you very much folks

Hello,

I just glanced over the notes (installation instructions) for the OBP 4.17.1 (patch 119234-01). ALOM >= 1.2 (very old!) is a prequisite.

There are later versions e.g. OBP 4.22.1 (patch 121683-01). Unfortunately the installation notes are contained inside the downloaded patch and not online.

The ALOM version can be reviewed via the ALOM management port (either network or serial). There is no need to shutdown the system to check the version.

This is a link to the ALOM 1.6 Administration Guide

http://docs.sun.com/source/819-2445-11/common_tasks.html#pgfId-1004756

For example, to display the ALOM version, type the following at the sc> prompt:

sc> showsc version

Hi Michael.

Are you sure that if I update OBP, my old memory modules with SPD 0 won't work anymore? I've been looking for some info about that but dind't find a clue. No warnings about compatibility between SPD 0 and any OBP version.

Sounsd strange to me, though. Normally new versions are compatible with everything older versions were compatible with.

I don't wanna take the risk of losing one of my machines by making that mistake: I refresh you my situation: I have an old sunfire V210 with OBP 4.8, and a sunfire V210 with OBP higher than 4.11-4, I guess (Because it came with modules with SPD 1.0). I want to swap memory between them (all the memory, for not to mix up SPD revisions in the same machine). To do that, I need to update the old machine's OBP to a higher version than 4.11-4, but if SPD0 modules won't work under OBP newer than 4.11-4, the old modules won't be useful in both machines, so one of them would be null.

I re-read the notes for these modules (370-6202) in the SSH and must confess that I was wrong.

Mixed speed or mixed SPD DIMMs on the same board is supported in OBP.

Mixed speed or mixed SPD DIMMs in the same bank is not supported in OBP.

Mixed speed DIMMs in different banks serving the same CPU run at the lower speed.

From the first point I conclude that the SPD 0.0 DIMMs are supported even with the later OBP. Later OBPs "understand" the changes in the SPD specification (0.0 -> 1.0) and can program the memory controller accordingly after reading the SPD.

I think rukbat had the decreased performance (point 3) in mind ...

Sorry for the confusion !
