Hi all, I'm new to this forum and kinda new to PC building however I have always dabbled in the subject so am fairly clued up. I have been browsing this forum over the past few weeks for all the useful information it can provide and decided this is probably the place to ask about the issues I've come across!
To start with, I recently got into a bit of PC gaming on a "gaming" laptop I bought and have to say I much prefer it to console gaming (long time console gamer here) so I decided to try step it up a notch and build a PC for gaming to take some stress off the laptop. Plus a friend of mine is currently building a gaming rig for himself and I wanted to try match the performance for less than half the price (it's just what I do).
Anyway I aquired my parents old and slow HP desktop to see what I could do with it. First I stripped it down and removed all the fluff/dust from the board, heatsinks, bloody everywhere! Suddenly it wasn't so slow anymore, I did decid the old pentium wasn't going to do the job though and needed to come out and be replaced with something a bit beefier. After a long time researching online, I came to the conclusion that I could infact modify and fit a socket 771 Xeon E5450 to my domestic HP pavilion home PC. So I did. I bought a used but working condition CPU off ebay for a total of £30 (lol) along with a mod sticker which I fitted succesfully and modified the socket to fit the processor (I'm assuming I did this succesfully). Now this is where my problems began, the computer boots succesfully and I can see the processor model in the bios, however, occasionally it will hang or freeze on the 'starting windows' screen. It does occasionally start after some waiting, it has automatically installed the E5450 drivers (4 of em) and does run. However it is quite laggy and for some reason, it either utilises around ~70% of 2 cores and ~5% of the other 2 of vice versa (practically mirroring itself).
I did remove the E5450 and replace my e5300 (pentium crap) back in the board to test I hadn't damaged any pins, it booted up and ran exactly as it did before. So the Xeon is back in and the BIOS has been reset once again.
I'm currently attempting to update the bios to see if that resolves the problem, you never know..
HP Pavilion P6203uk
Pegatron IPMEL-AE motherboard (G41 chipset)
2x 2gb DDR3 (667mhz) 4GB total.
320gb WD HDD 7200rpm
Now I do know the motherboard supports the Core 2 Quad (Yorkfield) CPUs which have the same architecture as the Xeon I'm using so I see no reason as to why it isn't functioning properly. The E5450 has the same frequency, fsb and even a lower TDP than a q9650 (which was an option).
Bare in mind I do have a corsair 600W semi modular PSU arriving today aswell as an arctic freezer 13 cpu cooler and a sapphire hd6950 which will all be fitted today at work if all goes to plan. I will be upgrading to 2x 4gb 1333/1600mhz DDR3 RAM at some point in future, maybe sooner if it's the issue.
I am a service engineer and very detirmined so please try not to make suggestions like "get a new motherboard and an i7" because you will just be ignored. If I can't get it working, I'll just overclock the crap out of the pentium and upgrade the CPU/mobo in the future to something actually suited to each other. This build is about performance per £ not performance flat out and I'm not scared to get stuck in and try make something work.
So, any ideas? Could it be the fact the RAM is a much lower frequency (667mhz vs 1333mhz, I wouldn't have thought so), maybe the processor isn't drawing enough voltage, does the bios need updating/modifying or could the processor itself be faulty? I do believe I'm the first to attempt a Xeon on a Pegatron domestic PC mobo but theoretically it should work so I want to make it work.
Any help and questions will be eagerly awaited and appreciated.
