Just to be sure:

(1) Is your SN95G5v2 really a BOM 21? Your BOM 21 v2 worked well with the Venice core AMD whereas rover220's BOM 21 v2 didn't work with the Venice core.



(2) Where do you get your reading of your X2 as "Manchester core"?

My system really is a BOM21. It says so on three different labels. The Motherboard is also BOM21, it says so on 1 label.

I get reading as Manchester core from CPU-z. CPU-z also produces a report that analyzes the sytem.

[rover220]

Rosewind..
I will check it out when it arrives ,and post as soon as I can be assured all is OK.
It would appear I could end up with an E6 or E3 depending on what's in the box.
I wish people would label things properly ,save a lot of agro.
Fingers crossed so tight now ,starting to get blood starvation.
LOL..

[Rosewind]

Thanks imax8. I just needed to verify.

So we have one BOM 21 that works both with a Venice and the X2 Manchester core, and we have two other BOM 21s that don't work with the X2 core.

[Rosewind]

Bump!

Rosewind and all other forum Friends..
Got Dual Core 3800 today ,fitted it ,and all is A OK.
No probs ,no AGP light ,all on BOM21 system Ver2.

I know it's not a V2, but I've got an SN95G5 v1.2 BOM 11 (I believe) and this is what I just did:

Opteron 170 running @ stock currently

http://www.exitcodezero.com/uploads/images/Opteron_X2/

[d4n13l]

It is working!! I got my Opteron 165 yesterday and it's running at 2400MHz with default vcore on my SN95G5V2 BOM23.

Edit: On the same machine an E3 Venice didn't work.

[imax8]

Been trying to clarify some issues about x2 processors. It seems that the difference between Toledo and Manchester cores is that Toledo has 1+1 MBs L2 Cache and Manchester has 512+512KBs L2Cache.

the other difference between other cores in the series are Stepping and Clock Speed:

4800+ E6 2.4GHz
4400+ E6 2.2GHz
4600+ E4 2.4GHz
4200+ E4 2.2GHz
3800+ E4  or E6 2.0GHz

The E6 version of the 3800+ works with SN95G5 V2 and the E4 version does not, it seems. It would be interesting to know if 4800+ and 4400+ E6 work but 4600+ and 4200+ E4 have problems.

It seems most Semperons are E6 but some are E3.

[rover220]

imax8..
X2 3800 I've just put in my SN95 V2 is E4 stepping ,no probs so far.
Perhaps I'm just one of the lucky ones ,Venice core didn't work tho.

[imax8]

Another pet theory of mine undermined by fact!

I doubt that luck comes into it. There is likely to be some issue of electronics or construction that makes the difference between success and failure. Unfortunately AMD and Shuttle are not too helpful in explaining what it might be.

Anway, congratulations.

i think the oddity is proven by my sn95g5v1 (1.2 bom 11) successfully running a toledo opteron 170 dual core just fine....

[noluckjim]

SN95G5 V1.2, BOM 11, Opteron 165.

Priming now

[heliotrope]

I have a SN95G5 v2
It says BOM 21 on the bottom of the case, but on my BIOS chip it says:

23
FN9520A

imax8 said above that the sticker on the BIOS chip also is the BOM number.  So which BOM is my system?  21 or 23?

[imax8]

heliotrope

The Bom21 on the bottom of the case (plus agp socket and psu) is the system number. I believe that the BOM 23 sticker on the BIOS chip is the motherboard BOM. There are FAQs about the significance of the numbers on the Shuttle site. The FAQ decribes a different location for the sticker. The numbering scheme is consistent, so it seems logical to assume that the sticker on the BIOS describes the Motherboard.

[Rosewind]

Congratulations are due to the fortunates who have Toledo core, Manchester core or Opteron X2s working in their BOM 21 and 23 v2 machines despite what Shuttle says on their web site. The same goes for BOM 11 v1.2 owners with working Opterons!

As you have probably already seen, I already edited my original message to reflect the X2 experience of happy (and unhappy) SN95G5v1.2 and v2 users.

[Rosewind]

Bump.

[SCSI]

My SN95G5 V2 seems to have BOM 24 according to the last digits in the SN in the PSU. Am I the only one with a BOM 24? Haven't bought an X2 yet but I am planning to.

[Rosewind]

Hi SCSI.

You are the first person to post a BOM 24, but surely there must be other people around. If you are lucky, they may even have beta-tested the X2 cores for you!
-----------

In general it would be nice to know how many motherboard BOM revisions there are of SN95G5v1.x and SN95G5v2.

I will include the BOM numbers as they roll in. I have already included BOM 24 in the list at the top of the thread.

[adams]

what i found at the bottom of my sn95g5 v1.2 is this: 95G511015GV3GH0, the agp slot's one :NG5G00440D03983, on the bios chipset: 183521504 and the one at the psu is exactly the same with agp slot one.

Anyone can tell me what BOM i got ?

should be 11

[imax8]

The numbering scheme and the sticker locations changed after the V1 was launched. See Here

This is not accurate but a useful basis for speculation.

I think Damien is right, adams BOM is 11. The sticker on the bottom of the case is the System id and the two digits following the xpc type (95G5) are the BOM number.

[adams]

thanks guys
i'll get opteron 170 in the near future.

[SCSI]

After looking at the "Identify_XPC" link provided by imax8, my V2 is actually have a BOM 21 instead of 24 like I posted earlier. I won't be upgrading to dual core until the M2 socket.

[Rosewind]

I have updated the BOM number info so it is also correct for v1.x owners. Thanks are due to imax8 for the correction.
------------

EDIT: SCSI.
You may still be able to go the Manchester X2 path. Pay attention to imax8's and rover220's posts, though.

[Rosewind]

imax8 keeps checking up on my data - thanks a lot. The rest of you better do the same ... or better become beta-testers for the common good

I admit that I get confused at times over this Manchester E4/E6 stepping thing. People with BOM 21 SN95G5v2s need to be very careful when they purchase X2 Manchesters:

(1) The people who know that AMD Venice cores worked in their BOm 21s, should go with the E6-stepping Manchester core - check out imax8's posts in this thread.

(2) The people who know that AMD Venice cores did not work in their BOm 21s, should go with the E4-stepping Manchester core - check out rover220's posts in this thread.

There have been three very disappointed BOM 21s in this thread (alchemist, Nicolas and SCSI). Perhaps they should try the alternative Manchester steppings before they give up their dreams for X2s?
