As a newer member I'm trying to tackle a project but somehow got in a little over my head...despite how replacing a CPU is about a 3 on the 1-10 scale of hard stuff to do...but I really need some help.
“Error Unsupported CPU Installed” message after updating my Pentium 4 processor from 3.0Ghz up to 3.4Ghz…HELP!
I have an older HP a1240n desktop computer. It was purchased a while back. It has a 3.0Ghz processor (which uses an LGA 775, “Socket T”, Intel desktop CPU socket.) It worked just fine, but a little slow for my wife’s home office needs. It has a Asus PTGD-LA (Goldfish3) Goldfish3-GL8E motherboard, as shown here:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c00361570
• According to the boards specs:
• Socket: LGA775
• Supports processor up to 3.4 GHz
• Supports Intel Pentium 4 HT processors
The Base processor is a Pentium4 630 (P) HT 3.0 GHz:
• 800 MHz front side bus
• Socket 775
Based on my research for the Goldfish3 motherboards specs, the largest CPU it will support is 3.4Ghz, so I bought a Intel Pentium 4 3.4 Ghz / 1M / 800 Mhz socket 775 CPU processor SL7J8
The CPU I bought is used and was sold as “tested” and passed.
It’s a Intel Pentium 4 550 Processor - 3.4GHz
Product Features
• Frequency (MHz): 3400
• Frequency (MHz): 800
• Socket: LGA775
• Level 2 cache size: 1MB
• Thermal Design Power (W): 84
• Brand Name: Intel
• Model: JM80547PG0961M
I bought one like this one shown here: http://www.amazon.com/Intel-Pentium-SL7J8-3-4Ghz-Socket/dp/B000YJAY4Y .....only I paid about $5 bucks for it.
Once I installed the new processor, I tried to start up the computer system and pressed the F1 key to get the bios screen to appear ( I think it's F1 on my system...but not really sure) but all I get is a message “Error Unsupported CPU Installed” and the computer will shut off in a few seconds. Which it does.
Did I buy the wrong CPU? I researched it and found that the 3.4Ghz socket 775 CPU processor SL7J8 is the 550 processor and all looked correct for a match. I’m not sure what I did wrong or if I have to manually clear the bios as shown here (near the bottom of the page) http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c00361570#N519
I found a chart that shows the processors but I lack the experience to determine if this is the correct CPU or not http://www.cpu-world.com/CPUs/Pentium_4/TYPE-Desktop%20Pentium%204%20Prescott.html
And from the same reference source, here is the SL7J8 (which is what I bought) http://www.cpu-world.com/cgi-bin/IdentifyPart.pl?PART=SL7J8&PROCESS=Go
What the heck did I do wrong? This seemed like a pretty easy project...even for me???
