Hi,
it appears that one out of the 5 bolts to remove to heat sink seems to be a 3.5mm hex screw rather than 3.0mm. It's the one that is located on the left side if you look on top of the sink:

Strange but the 3.0mm hex driver simply does not fit and a 4.0mm is too big.
I had to reassemble my MacPro without being able to replace my CPU...

Peter

Peter,
The bolts should all be the same. If you are unable to lock the hex driver into the bolt, then that one might be stripped. A mishap at the factory, perhaps?

Just keep trying. I don't know what to do if it is stripped, but let's hope that it is not.

The 3.5 might be able to get a grip on it. Do you have 3.5mm hex driver?

I looked at the screw with a LED light and it does not look stripped. The 3.0mm hex driver fits very loosely in and turns with no sound or resistance. Unfortunately, I do not have a 3.5mm hex driver at home right now.

Just a quick update: The screwhead itself looks different from the other 4 - slightly rounder and a little more bulky. I will try a 3.5mm hex driver tomorrow.

Hi,

Or you could try T15 screwdriver the actual size needed for the screws.

I have neither a 3.5mm hex driver nor a t15 screw driver at hand - I'll have to get those tomorrow morning. Guess how impatient I am with having a brand new 3.33GHz six core processor in our home and all screws except one turned loose...

Hi,
Your welcome you may as well be using the proper tool for the job, I fail to see why people keep on the hex key idea.

I had to use the T15 for one screw and the 3.0mm hex driver for the other 4 screws as my T15 was a few mm too short. However, my MacPro is now running with a 3.33GHz 6 core, 24GB 1333MHz RAM and without doing much CPU work the cores are between 87 and 100 degree Fahrenheit.

Upgrade 5,1 Single 2.8 quad to meet ESXI 5.5 minimum specs

Hi,

I am wondering if anyone has upgraded a MacPro 5,1 (Mid 2010) single processor, quad core, 2.8Ghz xeon W3530 to a Xeon 56XX processor. I use this machine to run Vmware ESXI 5.1 and I am looking to upgrade to ESXI 5.5.

The vmware web site shows the minimum supported hardware to be a macpro 5,1 2 socket with Intel X56XX processor. I am hoping to get away with a single socket X56XX.

I think i am right in thinking that the single processor board on my macpro can support an X series processor. But i wondered if anyone has done this and was there any issues with heat.

I have read the thread so sorry if i missed this, if already answered.

Just wanted to chime in: I just upgraded the CPU of my 2010 Quad 2.8 with the Intel Xeon W3690, and it worked like a charm. Geekbench 64bit Multicore score is 16118 instead of 8413, which is awesome :)
I paid 386€ (roughly $530) for the used CPU, the price for a new one is about 1100€ ($1500) in Germany. Including taxes of course.

I used the description from Arctic Silver for applying the thermal compound, it was my first time using thermal paste and it was rather easy with the description and a few videos on Youtube.

The screw driver was this Torx 15 (T15) and it worked fine. Stress test shows the CPUs are idling at their normal temperature and even when maxing out all 6 cores / 12 threads they didn't go above 80°C.

So thanks for this thread and the pictures etc, it helped a lot.

.

I have just done this.

I own a single-socket Mac Pro 4,1 (2009). I replaced the W3520 processor with an X5650.
It works just fine. I have not had any problems with stability or temperatures. In fact, temperatures are lower with this chip. Fan speeds are all just as they were before the swap.

I am very pleased with the behavior of this processor.

I've been working my way through this thread to review my options. Is there a list anywhere of what processors work? Or just basically that anything using the LGA 1366 socket is good to go?

yeah 3 cpus are worth it the 3670 3680 3690

you could use this one but it is a quad core not much bang for the buck

^^^^56 series Xeons meant for dual CPU operation will also work in single CPU applications.

Thank you for the replies. I'd be looking at upgrading a dual processor machine.

Flowrider, when you say 56 series, I see that both the X56xx and E56xx chips use the LGA 1366 socket. So those will work too? The W36xx are EOL, so supplies seem to be drying up.

^ ^ ^ ^The 5600 series are meant for Dual CPU applications, but will work in single CPU applications as well. The 3600 series will work in single application CPU applications only. As far as the E or X prefix. The E stands for enterprise and is used in the slower clocked chips. The CPUs with the X (or extra) are higher clocked CPUs and yes they are interchangeable, however in a dual setup the chips must be matched (that is the same PN).

Just finish the single W3690 upgrade today, everything went well.

However, my RAM still running at 1066.

I am using the ADATA non ECC 1600 RAM (I was not intend to buy the RAM that with higher frequency but I cannot use. However, this is the cheapest and easiest 8G stick that I can get from the computer shop, and I know it will automatically lower the frequency to match with the system), technically, it can run at 1333.

I replace all the RAM by my odd Kingston 1333 4G sticks, after a PRAM reset, the system can run at 1333.

However, after I swap the ADATA 8G sticks back into the slot, the system go back to 1066 again. Another PRAM reset, nil help.

I know the performance difference is small, but I just want to figure out whats happening.

Also, the 1600 RAM is CL 11, and now it run at 1066. Is it mean that the system is now running at 1066 CL 11?

sorry guys need help here :)

Hello everybody and thank you so much for this chat, i foud it very interesting,
i would like to know wich processor you suggest to buy for my mac pro,
i have a 2 x 2,4 ghz mid 2010, and i would like to buy this processor:http://www.ebay.it/itm/Intel-Xeon-W..._Elektronik_Computer_CPUs&hash=item258c5d421a

firsth question , does it match?
second question, do i need to buy two of them?
tirhd question, once i put the new processor does my ram still able to work? i have 8 x 4 gb ddr3 ecc 1066 mhz

sorry for my english, can't wait an answer from somebody!

thanks

Martin

A1) CANNOT, W3690 is for single CPU setting. For dual processor Mac Pro 2010, you should use X5690, unless you want to run your Mac Pro with one CPU only. Which you have will some single core performance improvement but almost no multi core performance improvement compare to your current config.

A2) Yes, if you decided to upgrade your processors, you should by 2 same CPU.

A3) Yes, your RAM will work fine.

thank you so much,
i will post soon the benefits of the upgrade!

Your question was answered in my post above:

^ ^ ^ ^The 5600 series are meant for Dual CPU applications, but will work in single CPU applications as well. The 3600 series will work in single application CPU applications only. As far as the E or X prefix. The E stands for enterprise and is used in the slower clocked chips.

You cannot do what the quote below suggests:

A1)unless you want to run your Mac Pro with one CPU only. Which you have will some single core performance improvement but almost no multi core performance improvement compare to your current config.

If you try to run with one CPU your fans will run at full speed, be unbearably loud and burn themselves out. In a dual CPU machine you NEED to run dual CPUs that are the same speed, make and model. They don't need to be matched but they do need to be the same.

A3) Yes, your RAM will work fine.

Your RAM is currently running at 1066MHz. The new CPUs will let the RAM run at 1333MHz, if the RAM is so rated. Check the speed of you RAM to make sure it's rated to run at 1333MHz.

Xeon x5690 6 core del processore ghz 3.46 slbv3

so if i'm not wrong i can put 64 gigs instead my actually 32 gigs when i upgrade the processrs?

another question, the one that i look for are quite expensive, does anybody know if there are some processors that have the same power for less?

thank you

Upgrading a dual processor Mac Pro is going to cost roughly twice as much as upgrading a single processor one. Unfortunately, the processors for a dual processor Mac Pro are still commanding high prices.

Here's a list of processors to choose from for a dual processor Mac Pro. You'll want two of them.

X5690 3.46GHz
X5680 3.33GHz
X5675 3.07GHz
X5670 2.93GHz
X5660 2.8GHz
X5650 2.67GHz

Four core:
W5590 3.33GHz
X5570 2.93GHz
X5550 2.67GHz
E5520 2.26GHz
E2650 2.4GHz

The W5590 (ie four core, 3.33GHz) processors turn up on eBay US at reasonable pricing. There is a listing for them at $US239 each here: http://www.ebay.com/itm/141080679324
