Dualies only running on one cpu.

[hawkeye177]

my dual 800s are only using one cpu. I am running on win2k. I have a D6VAA and I have the original bios. Should I upgrade to the latest bios? I know it is only using cpu because when the comp starts up it only says one cpu and every where else in windows it says on cpu. Please help

[fshanda]

Im not positive but I think the 2nd processor will only be utilized by smp enabled software. The system Im building is for my wife for running Photoshop which will take advantage of dual processors.

I had the same problem, try this: In your device manager, click on computer and see if it says ACPI Multiprocessor PC or MPS Multiprocessor. Of course if your motherboard is ACPI compatable then this is where it should be. If not try updating the drivers for this and click on display a list of compatable drivers. Then you will have a choice of what to choose. Now I'M NOT AN EXPERT. This is what I did to fix mine. I'm just trying to guide you in the right direction. I hope this helps.

[ooops]

Just asking , but are these 800's Celeron's ??? If so , I believe Celerons aren't SMP enabled anymore .... I've got the same board running PIII's , the BIOS shouldn't be the prob. And in the device manager mine has ACPI Multiprocessor PC.

[hawkeye177]

I tried installing a new bios but nothing. I tried to look for the multiprocessors support and it had it. What else is there?

[Mntsnow]

Did you originally install your OS when you only had the ONE cpu in it? If so you need to reinstall as the OS is not configured for the second CPU

[hawkeye177]

Also all my benchmarks are all of.
My system 35335MIPS
18562mflops
Athlon 1.2 3366MIps
1650mflops

[hawkeye177]

i had 2 cpus when I installed win2k.

[Sterling_Aug]

When you click ctrl-alt-del and task manager comes up, click on performance. Do you generate one or two CPU usage charts?

[hawkeye177]

It one showed one cpu.

[hawkeye177]

I was running win98 before on the same HD and comp. Could that be it. I format the hard drive so there would not be anything on the HD. Should I start over. I also want to say that when I installing win98 both cpus got hot. So i dont think one cpu is dead.

[NDC]

No, it wouldn't matter you had Win98 installed before you formatted the hard disk to install Win2k.

Look in Device Manager to see what type of HAL it's using. It's under "Computer". It should be "ACPI Multiprocessor PC" or "MPS Multiprocessor PC". If it doesn't have either of the above, HAL for single processor was installed...

[mtpros]

You do not have to reinstall the OS to upgrade to a multi-processor HAL. To fix your problem right click My Computer select properties. In the system properties window select the Hardware Tab. Under the Device Manager Field click the Device Manager button. You will see your computer there with all of its devices listed underneath. The first item listed should be Computer click on the + to expand it. You will see ACPI Uniprocessor PC right click and choose properties click the driver tab click the update driver button the upgrade wizard will start this will allow you to upgrade the HAL to a Multiprocessor PC. Hope that helps.

[hawkeye177]

Ok i changed the uniprocessor support to multiprocessor support but now it benchmarks like a regular PIII 800. Also there is only 1 cpu in the ctrl-alt-del thing. WHY WHY does these computers never work for me.
I still need help

[hawkeye177]

Could it be the bios, because the bios update did not work, I think.

[qwerty12345]

I think you have to change something in the view menu of task manager to see one graph per CPU.

[hawkeye177]

Nope it is not that because I tried to change it to one cpu per graph but it would not tell me. Also I talked to a guy who has lots of experince with dualies and he said that it is something on th emobo because windows cannot figure out it is a dualsystem unless it is told . Also on the teh start up screen I see (8.0*100=800 1 cpu(s))
Thanks for your help qwerty. Hey that is a easy name to type, because it is the name of my keyboard.

I recently purchased a motherboard from a retailer (memory media.com - product code # 10630 ECS MB D6VAA-RAID VIA694 DUAL).



Devices:



Power Supply: 400 W output

CPU1: Intel p3 933/256/133/1.7V

CPU2: Intel p3 933/256/133/1.7V

NIC: 3com 3c905-TX (WOL connector attached.)

VGA: 3d Prophet II GTS 32MB AGP 4X

RAM0: 512 MB SDRAM Standard Density - Generic

RAM1: 128 MB SDRAM Standard Density – Generic

DVD: Samsung DVD model SD-608 (currently unattached until I RTFM on how to connect to the HP RAID controller.)

CDRW: HP 7100+ 2x

FDD: Sony3.5”

HDD1: IBM 8GB

HDD2: Maxtor 30GB 7200RPM UDMA66

HDD3: Maxtor 40GB 7200RPM UDMA66

Power Fan: Jury rigged to inside air intake to increase air into power supply.

CPU1FAN: Power plug plugged into the CPU1FAN supply.

CPU2FAN: Not presently in, but when it is, it is in the CPU2FAN supply.

Chassis Fan1: In the Chassis Fan power supply.

Chassis Fan2: Powered via a 4 pin power adapter. Physically attached to the inside of the fan assembly.

BIOS: DV6AA Ver 1.2e 04/26/01 (694X-686-D6VAAC-00



Problem:

When CPU1 is in the CPU1 370 socket, everything is normal and fine. In fact, I am working with it now on this computer.



When CPU2 is inserted, the system powers up and the drives spin, yet there is no POST beep(s) and the HDD LED lights up with HD activity due to spin up but the monitor does not come out of standby.

I thought it might be a case of not enough power for all items, but I systematically removed 1 device after another, until I was left with just HDD1 \ CDRW \ Chassis Fan1 \ RAM0 \ CPU1 \ CPU2: NO effect.
I then removed CPU2 and rebooted and powered up normally with no problems.
I then added one item at a time from all of the items listed above with the exception of: CPU2 \ CPUFAN2 \ DVD. Between additions, I would boot up and check for functionality and then once confirmed, shut down and then add the next item. Each time I did this, the system worked perfectly.
I then switched CPU1 and CPU2 and booted up. The system works perfectly.


I have not checked to see if the VIA chips have been flashed to the latest 4in1 drivers yet, but do not think that it is pertinent at this time due to the fact that CPU1 works fine by itself.



It is not the VGA, as it works fine when just CPU1 is in and not both CPUs in at the same time. I even swapped it out with 2 other known good working VGA’s and still no change.



During the course of all of this, there was one (1) instance where both CPUs were detected and the system started to boot. At the time, I thought that I had narrowed down the problem to RAM1 due to the fact that when I took that out, the system booted and detected both CPUs. But, before the system could boot past the IDE drive detection phase, I powered off and put the case cover back on and then booted again. Nothing happened other than the problem that I have described above. So I took out CPU2 and started writing this e-mail to you guys.





Additional:



I am at a loss as to what to do.



I don’t think that it is a resource conflict as the problem occurs before the device configuration.



Please assist.

Now that you have multi processor support just go into task manager and pay close attention to the view options. Make sure one graph per CPU is selected.

Also for future reference, WinNT 4.0 will update to the multi cpu kernal by running the latest service pack. Win2k did away with this by allowing a kernal change via device manager as described by mtpros.

On some motherboards, if you have the 2nd VRM installed - even though there's no CPU Win2k and WinNT4.0 will install the multiprocessor kernal during initial setup anyways.

Oh, now that your kernal is replaced you might want to create a new emergency repair disk. Goto start, programs, accessories, system tools and then run backup. From the menu bar click Tools and then create emergency repair disk. (For those running WinNT4.0 just goto start and then run. In the open feild type rdisk and then click ok)

Did you enable ACPI in the BIOS so Windows can correctly work with the ACPI Multiprocessor HAL. If you are using the MPS HAL instead, you may need to change the MPS version level in your BIOS.

Good Luck,

thanks for all th info :)
