I got bored so....

No haven't ordered it yet. Watching one on eBay that ends in about 24 hours. But sure, if you're not using it and it's a 2350 (or close to it) i'll gladly put it to work. Let me know what you find.

It's not a Dimension 2350 but an Optiplex GX260. Similar chipset (845g or 845gl). I think the main difference on the Optiplex board is an AGP slot. Dell Service Tag 8333V21. Let me know if you want-

Sounds perfect. I'll take it I'll swing by and pick it up whenever is good for you. Took the week off work so any time is fine.

Yeha, I was bored also and start on studying computers hardware, linux software and other complementary stuff. I am tired of passing for a very stupid guy concerning this computer thing.

I was bored, so I am builting a farm, with 3 computers with 14 cores and 3 GPUs, in about a week I will send all the pictures, I will detail it on the pictures that is what I am doing now, not time to make the usual posts with carefull graphics, I am preparing the detailed transformation, step by step.

Rocket computers with old and new stuff on the way

You will see the Duke Offensive ... in a flash.

Any luck with the P4 Dell box?

Strange thing happened actually. I got it running and found a 2.2GHz CPU to replace the 2.0 GHz CPU. 10% faster, but the WUs completed 3% slower, even after going from 512MB RAM to 2GB. I need to look into it a bit more to see what's going on. Ordered a 2.8GHz CPU which should be on it's way, but coming from China so who knows when it'll arrive. Only $10 though so can't complain.

Enjoy reading your story here John.

I have discovered that reusing/rebuilding old computers can be quite fun because it gives us the chance to add newer technology to older problems.

Will start posting my computer rebuild stories soon!

Was it the same "version" of P4? They changed the pipelines quite a bit on some of the revisions, so if it's a longer pipeline revision of the P4, that 10% MHz gain might have come at a 13% IPC cost, so your net was -3%. Not sure that would be the answer, but it's possible.

Yeah was the exact same kind of P4. The chipset only works with the P4s that have the 400MHz FSB. No wiggle room there at all.
