I had a MSI K8D Master3 (380 Euro, Two Opteron 240) which drived me
crazy and I have tried to run one of those CPU's on a Singel-Opteron
mainboard from Tyan and it does not work.

Then I have bought two Tyan Dual-Opteron Boards andused it with only
one CPU each, which works very fine.

Then I have tried to run a Opteron 142 on a Dual-CPU-Board and it does
not work.

So you NEED the right CPU to your Mainboard. You can not use a 1xx on
a Mainboard which was made for a 2xx.   



I wonder if that is for technical reasons, or just lack of cpu support
in the bioses.


The Opteron 1xx series of processors are basically conventional Athlon 
64 939-pin processors with an extra pin.


I'm not sure if this is CPU related or if its mobo chipset related, but 
there is a significant difference between the 939's and 940's, as the 
939's like standard unregistered memory... 940's will only take reg 
ecc.   Hence the reason they went from the 754 to the 939 since no one 
wanted to buy the more expensive ram necessary to run it (possibly other 
reasons too).




The Opteron 2xx and 8xx series, however, are different--they both have 
a different count of what is called coherent HyperTransport links. 
These links are used for transferring SMP protocol type things (cache 
coherency checks, cache snooping, etc) between processors. The 2xx 
series has one of these links (it can connect to one other processor), 
while the 8xx has three. This is the reason why you can't use a 1xx 
processor in a 2-CPU system, or a 2xx processor in a 4 or 8-CPU 
system, but can use an 8xx processor everywhere (the extra coherent 
links just will not be used).


Actually they were reffering to the fact that a 1xx would not work 
period on a 2xx board.  From what I understand the HT pathway is only 
used when using multiple cpus (ie: cpu to cpu communications).  So even 
if you use one lone 1xx cpu, aparently, its supposed to work on a 2xx board.

I guess thats what I'm the most curious about; mixing these dual and 
single core processors.  Do the required Hyper Transport pipelines match 
up when you use a dual with a single?


If so... how do you match the duals with the comparable single cores 
since it seems they use a different naming scheme (ex: single 244 = = 
dual 265).  It all seems 'theoretically' plausable, I'm just wondering 
if anyone has actually tried yet.

Awesome, found the thread...very insightful.  I was under the impression

not.   Seems like the only issue would be finding how to match them, and 
as you mentioned before with the AMD site, probably easiest way is to

Generally it's not a good idea. You've got timing issues to consider,
among other things.

Has anyone ever....

2005-06-21 Thread Nathan Dragun
Ok, I'm curious here.  I've got 2x512 sticks of corsair memory for my 
opteron, and unfortunately they are PC2700 and not PC3200. (Thinking the 
max FSB was only 333 when I first purchased this system 2+ years ago.)


What I'm wondering is; has anyone ever tried overclocking memory on 
their opterons?  Is it fesable?  Stability issues? - although thats why 
I mentioned they were corsair sicks, don't know if that would make a 
difference or not.


In theory I'd like to be able to run them at 3200, but I have no clue if 
this is considered possible, and I don't have time to pull it down and 
play with it.  Unless I know my efforts are not in vain.

I haven't tried it, but I suspect if you tell it to use them as DDR400,
it will either automatically pick slower timins for CAS and such, so it
will at best be rather slow DDR400 memory, or you have to make it use
slower timings to make it work.

I have used PC100 CAS 2 memory as PC133 CAS 3 memory before and that
seemed reliable.

Len Sorensen


 

Probably very unlikely that it would be stable with the same latencies 
and timings as the 2700 settings then?  I know that some chips far out 
perform what they boast, where others barely meet the expectations.  No 
clue if Corsair can hold these expections or not. : /

Re: Has anyone ever (overclocked memory on amd64)...

2005-06-21 Thread Nathan Dragun
Hm, unless I'm just used to being able to manually set 200mhz it would 
appear that I can adjust any and every setting EXCEPT this.  I can only 
limit the frequency...what sense does that make.


So right now I'm locked in at 166 it would appear with about 15+ options 
that I can vary on the memory, which makes me wonder if there is a 
certan combination of options that I can set to force it into a 200mhz 
frequency.


Any gurus out there have an idea?

I wish I could say how well this driver has worked for me or not, but I

Yep this is the TG3, but once again its always worked for me fine.

Hmm, expensive stuff.  I am not a scsi person anymore.  The high prices
and lousy performance I got from IBMs 15k rpm scsi drives and raid
controller a few years ago while spending a ton of money just makes me
not interested anymore.  SATA makes much more sense to me.
 

IBM drives have always been unreliable with nicknames such as 
'deathstar' for the deskstar series.  IBM sold their hard drive division 
to Hitachi who is now trying to create a new type of storage with deeper 
platters so that data can be stored vetrically on the disk instead of 
horizontally end to end.  (So from a side view the data looks like 
||| instead of --- )
Anyways, its too bad you didn't really see a performance difference for 
the money you paid, because I'd go SCSI any day.

True, but that may just be a flaw of the built in controller, not of
SATA.  You can't connect scsi at all to many machines, which doesn't
make scsi broken.  You can get SATA controllers that run 24 drives if
you want, and unlike scsi, they don't even share the connector but
instead use one cable per drive.

Len Sorensen
 

I hardly see how 24 cables versus 2 is hardly even something you'd have 
to consider making a choice about.  SCSI channels can take one heck of a 
beating, besides, your point is irrelevant since you can have the same 
software raid you'd use for SATA over several SCSI channels as well.


Lastly, all SATA drives have either IDE or SCSI interfaces anyways 
before they go to the SATA channel.

Actually, I run the S2882UG3NR and have run it almost since day 1 of the

First I had to edit /etc/dfsbuild/dfs.cfg, because the mirror setting for

Then I commented out the default mirror setting pointing to localhost as
it caused a fatal error when trying to rm some files. 


Now it bails out with:

 might do the trick
PasswordAuthentication is set to no by default, as enabling it causes

And yes UsePAM = yes was set, for clarification.  So I'd assume that

SSH package concerns...

2005-05-09 Thread Nathan Dragun
While setting up PAM in conjunction with SSH I included the following 
line to deny access unless found in the following file:

authrequiredpam_listfile.so sense=allow onerr=fail item=user 
file=/etc/sshloginusers

Which works, sort of.
...Lets say for examples sake the user bob is trying to get in, but is 
not listed in this file.  Ie: not authorized.  If I try to connect via 
the windows program PuTTY, the first attempt fails, naturally, but if I 
re-type the password when prompted it will let me in!!!  Not good.  I 
tested this several different ways and found that if I try and go from 
linux box to linux box after about 4 attempts it will let me in.

SSH package version: OpenSSH_3.8.1p1 Debian-8.sarge.4
in conjunction with: OpenSSL 0.9.7e 25 Oct 2004
Now I was doing some research into this, figuring I configured something 
wrong or what not early on when I first noticed this authentication 
problem existed and noticed that there have been some huge changes from 
the 3.8.1p1 release back in October 2004 (Ironically if I read that 
right 4.0 was just released today). Changelog: 
ftp://ftp.ca.openbsd.org/pub/OpenBSD/OpenSSH/portable/ChangeLog

But, why on earth is this package so out of date??  Insight into this 
would be greatly appreciated.
