MP 1,1-5,1 X5272 or X5482 for MP 3,1. Looking for Wolfdale.

[christiann]

Hi. I have a dual CPU 2 x 2.8GHz (8 core total) Mac Pro 3,1 running Mojave. I’m looking into a new CPU. It seems like the newest one supporting 800MHz RAM is the X5272 which is Wolfdale? The X5482 is really such a little speed boost. Should I even upgrade the CPU? I only use it for basic stuff, I think I’d need better single core scores. And yes I checked the compatibility chart, the X5272 for me is $10, but the X5482 is really expensive.

Let me know,

Christian

I've got exactly the same spec machine. I have thought about upgrading it too, but there is so little to achieve in there, so I think I will not bother. You have compared GeekBench ofcourse. I believe around 14% single core performance boost to achieve with X5272 over E5462.

And maybe check CPU-benchmark too, that gives us 16% single core boost with X5272 over E5462.

I don't think those numbers would be something you would easily notice at everyday use, would they.

Yeah, it doesn’t seem to be worth it. Also on the chart the release dates seem to be off as I’m pretty sure they were released in Q3 2007. I’ll throw an SSD and some more RAM in it though.

That's what I ended up with too.
RAM was cheap enough so put in 48GB. Had a GeForce GTX 680 4GB laying around. And I have this PCIe 480 GB AHCI blade in there too. Still trying to decide what OS should I run with it. Right now it's El Capitan booted of an old HDD. I am a little tempted towards some Linux flavours too.

You can find quite alot usefull information about upgrades with forum search. One is about 64GB RAM quirks. I decided to stay at 48GB to avoid all the fuss with that.

Happy hunting with upgrades

I was planning on flashing a 680 too. How much was 48GB? 800MHz stock RAM is expensive but 667MHz slow RAM is cheap.. 64GB 667= $99, 64GB 800= $298.. Should I pop in an M2 card, USB 3 card too? I still can’t decide if I should buy the slow or faster RAM though.

As you can see from screenshot I went with 667MHz. It was a fraction of the cost of those 800MHz DIMMs. Can't remember the price anymore. eBay cheap it was if I remember right.
