OPTY 165 CORE0 FAILS NEED HELP!

My friend recently bought an Opteron 165 from zipzoomfly.com with the CCBWE 0551VPMW. I am currently testing it in my hardware. Core0 fails anything at stock even, while core1 will run 2.7 stable. Am I doing something wrong? My settings are 300htt, 3x hypertransport link, 2-2-2-6 timings 5/6 divider 1.6v core. The cpu-z screen is linked:
I really don't want to RMA it and get the same stepping, but is it just a rare case? I would kind of like to avoid a freaking 15% refund too, but some things must be done...

Please help me as soon as possible.

I'm guessing you just pulled the chip in your sig, and plunked in the opteron.
Windows may not be set up for dual core, or your bios may only be initiating 1 of the cores. Check in taskmanager for 2 cores, and make sure your bios supports dual core.

I'm using a a 7xx bios for the FX60 that supports both dual and single core processors. I'm 100% sure windows taskmanager allowed me to run both CPU cores as I can set affinity for 2 superpi's to find cor0 fails. Also, in my BIOS load screen Award Bios indicates 2 cpu's are detected.

ACPI during install hasn't been set to use 2 core on your system. While the core will be detected, there is chance that there is no way to start it. You have to do some trick to start the second core.. And if you're smart enough, you'll figure it by yourself...

2.7Ghz is the limit of my Opteron 175.
I can overclock to 2680 but more an system is unstable, whether I use a 9.5x 10x 10.5x or 11x multiplier...

Seems the best affordable Opteron for overclocking is the 170

you sure? taskman does pick up the second core on the performance tab...

Devices manager does pick my printer but that don't mean I'm printing ...

Reply to pat

meh, im pretty sure it is utilizing that second core. other people that have the same stepping also are complaining about the core0 failing...

Rich, core0 failed superpi at 1.8 freaking STOCK. reallyyyyyyyy pisses me off. Also that site doesn't have my stepping, as its basically brand new =/

Reply to ak47is1337

What does the device manager tell you about the processor?

Or rather, in system devices and ACPI compatible system? (maybe not exactly that.. did it from memory)

Reply to pat

Ok, I checked out those things. Under computer in Device manager it says "ACPI Multiprocessor PC".
Under processors it has "Dual Core AMD Opteron(tm) Processor 165" twice.
Under task manager, it has the two-column cpu-usage chart it should. Anything else you want to know? Should I run Knoppix and prime95 or superpi or something to get a fresh install?

Reply to ak47is1337

Have you tried to run Knoppix on it?

It would be very interesting to see if the hardware is broken or windows is on crack.

Please try Knoppix 4.0.2 or better or FC4 x86_64 and let us know if it works.

[root@your_machine /]# cat /proc/cpuinfo

Good Luck!

No, but if I do, will Knoppix support running programs on A SINGLE cpu core? I need to run 2 programs to test the cpu errors, one one each. does knoppix support this? Also, will prime95 or superpi run on linux?

Reply to ak47is1337

then you may have something wrong..

Reply to pat

Possibly. But what? I cleared my BIOS before I switched and ensured I had a good dual core bios ready. Core1 works great but Core0...gives me errors. Therefore, memtest or prime95 will pass with flying colors because they are single threaded and can't go with 2 processors running. 2 superpi's running with one set to a core fails, as does anything else...

Linux will detect and use both cores if they are there.

Yes you can run multiple programs no problem!

I'm not sure if prime95 is available for Linux but there are many benchmarks which run on Linux including SPEC benchmarks, SPEC Viewperft, etc etc etc

I'll get you some links.

I don't need to run multiple programs, what I'm saying is I need Linux to be able to attach a certain program to certain core so I can make sure one core isn't helping the other. Can it do that?

700MB CD ISO

Fedora Core 4 [ FC4 ] :

http://mirrors.kernel.org/fedora/c [...] 86-DVD.iso

Using the DVD is strongly recommended the 64bit x86_64 version will run 20-30% faster or even better.

run up2date first if possible to upgrade the kernel!!!!!

PRIME95

SPEC benchmarks (VERY large):

I can come up with more if you are interested.

PLEASE let us know what happens!!!!!

Good luck!!

Linux will do it for you automatically!

If you have 2 or more CPUs or 2 or more Cores and you run 2 prime95s or whatever 1 will automatically run on CPU0 and the other on CPU1

You can monitor this by running "top"

[root@your_machine]# top

Got x64 fedora downloading. The prime95 link is down though =( Will I need to install this, or will it run off CD? I really don't want to make space for linux on my windows drive...

FC4 requires an HDD install but IS 64bit!!!! Do you have a spare HDD you can install it on???? You can install it on a 10GB HDD and it doesn't have to be the primary master IDE. You can also install it on SATA just fine.

Knoppix will run entirely from CD or DVD no install required. The default Knoppix is 32bit so it will be slower than FC4 x86_64. I'm not sure if there is a 64bit version of Knoppix, if I can find one I'll let you know.

I have no spare hard drive. I'm canceling @ 123 mb...

Reply to ak47is1337

I found Knoppix 64 here:

http://www.applia.fr/contents/knoppix64.html

This is based on the older v3.4 branch and I've never tried it.

The current 32bit version is 4.0.2

The goal of this work is to provide a 64 bit development environment along with the usual desktop tools. This is the version I wish I had had when I did HPC benchmarking for a recent project. I then nearly missed the fact that when compiled in 64 bit mode one application showed a 65% performance improvement.

65% improvement on 64bit holly cow!!!!

Some stuff will run a LOT faster on AMD64 with a 64bit OS like FC4 x86_64 or 64bit BSD etc

On average you can expect it to be at least 25-30% faster but 65% is AWESOME!

Here are some FC3 i386 [ LEFT ] vs FC3 x86_64 [ RIGHT ]

You can see FC3 x86_64 is a LOT faster!

That link for knoppix 64 is down. Also, do I need 2 folders of Prime95 to run 2 instances of the program?

I guess you'll have to try Knoppix32 then from kernel.org http://www.kernel.org/pub/dist/kno [...] -23-EN.iso [ 700MB ]

Nope one folder is enough

You can simply

[code:1:ff320fe348]
[Console window 0]

[root@your_machine]# cd prime95_directory

[root@your_machine]# ./prime95

[Console window 1]

[root@your_machine]# cd prime95_directory

[root@your_machine]# ./prime95

[Console window 2]

[root@your_machine]# top

[/code:1:ff320fe348]

Top will look something like this except on a Dual CPU system you will also have a CPU column indicating which CPU the program is running on:

Here are some Knoppix screenshots

Click on the "TERMINAL" icon for a command prompt / console / konsole

http://spare2.com/knoppix.html

You can open more than one shell as a TAB just like firefox you can have several command prompts in the same window instead of 3 or more console windows.

Looks like there may be a few cores which may be flaky, I'm wondering if the problem occurs at stock out of the box or after they have been unsuccessfully overclocked.

If you contact AMD I'm pretty sure they would try to fix the problem as they do not want the bad publicity.

Have you checked the AMD forums?

Hey didn't Intel have a few bad batches too?

it happens at any speed, voltage or memory setting. its really pissing me off, as this defeats the freaking purpose of dual core in the first place. ill just call amd and tell them its for a high end workstation
