Dual quad core only recognizing single xeon-- help!
Hello,
I've seen this posted on a few forums so here goes. It appears that various folks have struggled with this process through Vista and Windows XP 64- This is my first post and I've heard nothing but good things about this group. Please help me!
INTENT: I am upgrading a Dell Precision 490 Workstation with Dual Quad Core Xeon Processors, 4GB RAM, and 160GB SAS ATA HD from Windows XP-64 to Windows 7 SP1 Professional 64-Bit. Fresh installation.
CHALLENGE: Windows 7 64-Bit SP1 Professional will NOT see the 2nd XEON processor.
THINGS TRIED:
THINGS TO NOTE:
- I used MSCONFIG in the start Menu. Went to the Boot Tab. Pressed the Advanced Options Button and on multiple boots did the following: a. Clicked on the multiple processors button and rebooted. b. Clicked it again and rebooted. I was only able to select 4 processors from the single Xeon that the system is seeing.
- I upgaded the system BIOS from Dell's A06 to A08.
- I entered F2 to enter BIOS setup and looked for any Multiprocessor menu's, support, HAL selection, etc... Nada. There is one menu for multi-threading which this generation of Xeon does NOT support (Xeon E5320).
- Went to my local computer store, bought some new heat-paste and reseated both processors. Rebooted and tried #1 and #3 again. No sucesss.
- I double checked all the other things you might think about. This is a stock Dell MOBO and I didn't see any CUDA-styled swith (like on the Apple) to reset the MOBO. There aren't any jumpers on this system to turn on/off a dual processor set up. I double checked all the connections to hard-drives, video cards, sound cards, internal USB, and the like with out any success.
1. The BIOS doesn't see anything but processor (0) with a single quad core.
THINGS I'M THINKING ABOUT:
1. I'm new to Windows 7 but wasn't there an ACPI HAL Stuff in Windows XP 64 that you could click or not click for multi-processor support vs. Single Processor Support. Where is this function if available in Windows 7 Professional?
2. I'm going to reseat the CPU's again but this time reverse them (put processor 0 in processor 1 slot and visa versa) so if one of them is bad, I'll see it in the BIOS doing this reversal. I just bought this unit refurbished so I believe I'll be in a good spot since I got a warrenty with it for 1 year and I can easily get a new part.
QUESTIONS FOR THE GROUP:
1. What else is there to try regarding multi-processor support from Dell and the Precision 490 when migrating from 64-bit XP to 64-bit Windows 7 Professional?
2. I do have a Windows Virtual Machine running XP 32-bit emmulator running on the system to use some software that isn't 64-bit compatible and probably never will. Could this cause a problem?
3. Are there any known issues regarding this mess?
