Will this Processor work in my MacPro 1,1

[SpencerJ]

I've done a lot of research on what processors I can use in my MacPro 1,1 and everyone says something different and I don't want to buy the wrong one. I'm looking to upgrade my 2.66Ghz duel core to 2.66Ghz Quad core.

I found these on eBay

It will work. The only thing is that's an older version of the 5355 which doesn't have G0 stepping, meaning it'll consume more power at idle. This thread has a great explanation: https://forums.macrumors.com/threads/1210403/

This auction has a matched pair of X5355 SLAEG Xeons for a decent price. http://www.ebay.com/itm/MATCHED-PAI...1-1-/261170383125?pt=CPUs&hash=item3ccef7c915

Thanks a lot!

Enjoy. My pro is great after doing the ugrade. And an SSD makes it stupid fast for a seven year old computer.

I just installed a 3Tb (3, 1TB drives) stripped RAID in it. It made a huge difference!!

Nice. That'll be in the works as I move closer to production this summer. Need more ram first.

I got 16Gb's pr ram from 18004memery on eBay for $120. I sent them a OBO and they accepted!

Sweet. Does that include shipping?

Yeah it did, sorry I forgot about this post lol

Good stuff. I'll have to check 'em out when I add more ram this summer. Thanks.

Going from 4 to 8 cores of the same speed won't improve anything unless your apps are beefy enough to use all 8 cores. The 3.0GHz gives an every-app improvement in machine speed.

Yeah I'm sure but I'm on a budget. Its about $75 for 2 2.66ghz or $300ish for 2 3.0ghz

In due time when they drop down in price I'll pick up a pair of 3.0ghz
