Re: two cpu's

The dummy voltage reg is just to complete the power loop, (as there is built in diags in the box) without the dummy the box will log errors against the empty volt reg slot. YES you do need the Voltage regulator for the 2nd slot if you intend to install a processor there.

IBMx3650 amber light appears , error indicates CPU

Most probably this would be Motherboard issue. Rare cases for processor fault. Easy to find out if server works on dual processor

Trouble shooting:
1: Perform Power Cycle (Turn off server, remove power cord from server and wait 15 min)
2: Try with minimum configuration (1 cpu, 2 ram )
(swap CPU if have dual)
3: Perform IMM update

If issue remains, replace motherboard and see if it solves issue.

Processor in incorrect slot system halted error


You don't see this often but when you do it means your cpu is not in cpu slot 1. (Usually you are also running 1 processor in your server.) Just move the cpu to the other slot, power on your server and you should be good to go. Be sure to only touch the edge of the cpu and not any of the chips in the middle.

Good Luck

How to get my server to show both processors in the task manager

Try under "options" menu to select "One graph per cpu" - also check under performance monitor to see if more than one processor is detected - if the OS is only seeing one processor, then you'll have to replace the HAL with the multi-processor HAL - not for the faint of heart, but certainly do-able. Check out this MS link (KB 156358), but the procedure differs by OS.

Cant boot celestica with 2 processors

Try upgrading the BIOS on the motherboard first. Then make sure that the CPU's match completely. Failing that, try to boot of each processor in socket 0, then socket one.

That will tell you whether its a processor issue or a MB / firmware problem.

No display on DL380 g4

This can be caused by a processor / VRM issue or even a system board fail. Try dropping to a single proc and VRM and swap test with the others.

No display cpu fan are'nt running though there is green and orange light on server

Hello there,

Check your power supply and see if its functioning.

CPU fan that does not run means there is no power getting into the motherboard.

Thank you for using Fixya

Processor support?

According to IBM, no. the fastest CPU you can use for the 8479 is a 1.26Ghz, 512kb Cache, 133Mhz FSB, Socket 370 Processor PN 32P0652. Made by IBM.
Also known as a PIII-S. You can get one for around $12 on Pricewatch.
I personally think it might work if it's a 512kb cache 1.45v chip; If it was mine I might try it, but I can't find even anecdotal evidence of anyone trying it. I'd put it at a 50/50 chance of smoking your motherboard, CPU, or both.

Adding a second processor to my 2600 server

I hope that you fixed your problem without troubles by now, but if you still have not, I can help. I added a second xeon processor to my Dell PowerEdge 2600 a couple of years ago.
Lay the server on its left side then loosen the three thumbscrews on the right front side and "slap" the cover off backwards.
You should have by now identified the current processor by running cpuid software that I think comes from Intel's website in order to buy an identical cpu. That was the hardest part, finding an identical one still for sale. If I remember the Poweredge 2600 could only use xeon processors with only up to 512 kb of cache or someother small amount and are not that available still new in the box.
You also have to get two identical voltage regulator modules (vrm). I was not able to get a second one for some reason and just bought two identical ones specifically for the xeon processors that I was using. Be sure to do your homework on this. MATCHING cpu's and MATCHING vrm's.
That's it. Each processor has two cores and you should see all four after you boot.
Another thing to think about would be setting the processor afinity to run your most intensive process to all four cores while only letting most applications to only use the first core.
I hope this helps if you haven't already had any success.
