Mac Pro :: 1333MHz Memory On Intel Xeon Nehalem 2.8

Jun 14, 2012

I have recently bought 2 4GB 1333MHz memory to be used with my Mac Pro mid 2010 nehalem processor. It works fine, turns on and all, but after opening a few programs and letting it run a little and i ask him to shut down, it takes me to the grey screen with the little rolling ball and does not shut down.

Mac Pro :: 2 X 2.8 GHz Quad Core Intel Xeon Memory Upgrade?

Oct 7, 2008

I would like to upgrade the memory on my mac pro to 8gb (4 x 2gb) plus the original 2gb (2 x 1gb) that comes standard for a total of 10gb. I have looked on [URL] and the prices range from $198.99 to $799.99 for 8gb (4 x 2gb) kits. The Omni Technologies Optival is mighty tempting at $198.99 and I see that OWC has 8gb for $269. What do you recommend? Is Optival any good? The reason I an adding 8gb is for multi-tasking video/audio etc.

MacBook Pro :: Possible To Use DDR3 Memory At 1333MHz?

Feb 28, 2012

I want to upgrade the memory for my 2.53GHz 13" MB Pro from 4GB to 8GB. If the system bus is 1067Mhz. Does that mean I need to be sure to get mem sticks that are also 1067Mhz?

Mac Pro :: Nehalem Memory -- 6 Is Better Than 8 Sticks?

Mar 15, 2009

Last night Lloyd Chambers of [URL] tweaked his DigLloydTools app (DLT) that we use to test memory throughput. It's now more accurate. The bad news is that it showed that when we put 8 sticks of memory in the 8-core 2.26GHz Nehalem, our throughput for memory read/write (memmove) dropped by 1/3. It turns a triple channel memory bus into a dual channel memory bus.

Specifically, in our test, the combined read/write throughput dropped from 9261MB/s to 6195MB/s when we went from 6x2GB to 8x2GB configuration.

Now, don't panic. That doesn't necessarily affect real world app performance unless the particular app you are running is saturating the memory bus. Which apps saturate? I don't know yet. I'm running our complete real world test suite including Pro Apps and 3D Games in both the 12G and 16G config. If I find anything that's significantly slowed by the 8x2G config, I'll post it here as well as on Bare Feats.

Mac Pro :: Win 7 On Intel Xeon Mac Pro - Getting Blue Screens

Jun 10, 2009

I have a Intel Xeon Mac Pro and I've been able to put XP and Vista on it without issue, but am now trying to put Win 7 on it and every time after doing the initial installing files and then reboot, it comes to a blue screen and reboots very quickly.

Has anyone run into this and if so have you found a work around?

For more info, I created a Windows partition in Leopard using the Boot Camp utility and divided my drive equally. Then I insert the Win 7 disc and click on the start install and it reboots. I select the Boot Camp partition and format it. It copies files and does the install process and eventually gets to a point where it reboots and goes to load the Win 7 OS and this is when it blue screens.

I have done all the firmware updates on my Mac Pro, I even tried it on another Mac Pro with the same results.

I've redownloaded the iso direct from MS and burned it using different brand disc and using a different burning app. I tried the 64bit version also and whenever I use that version it comes up asking me what CD drive, 1 or 2, I can't enter in a 1 or a 2 or do anything at all but turn the machine off. I even tried it on another Mac Pro with the same result.

I tried removing the OS X drive and having only 1 hard drive in the system that's just for installing Win 7 to, all to no avail. Every time with the 32bit version I get a blue screen and every time with the 64bit version I get the "which cd drive" screen and cannot do anything but power off the machine.

I was able to do an upgrade from Vista after installing Vista SP1 but after it completed and tried to load the Win 7 OS for the first time it again blue screened.

Mac Pro :: Initial Intel - Nehalem - CPUs

Jul 14, 2008


Pssst! Want an Intel 'Nehalem' processor on the cheap? Well, just go and ask the chip giant for one. It's 2.66GHz 'Bloomfield' CPU has been price at just $284, it has been claimed.

That's the batch price, of course. To get it, you'll have to buy a 1000 CPUs at once - boxed Bloomfields will come in slightly higher than that.

As previously reported, the 2.66GHz Bloomfield - Intel's desktop Nehalem - will also be made available in 2.93GHz and 3.2GHz versions. The pricing, posted by Chinese-language site HKEPC, confirms the latter will be an Extreme-branded gaming PC part - it'll cost $999. The mid-range Bloomfield will cost $562.

Mac Pro :: 3.33 GHz Westmere 6 Core Xeon Upgrade

Apr 14, 2010

I'm getting so bored of waiting for Apple to bring out a new Mac Pro. So I'm now thinking why it's not possible to upgrade the processors in my dual 2.66 quad core Intel Xeon Nehalem to the new Westmere 3.33 GHz 6 core Xeon processors.They run the same voltage range so the existing power supply should be fine, have the same 1366 socket and can use the same RAM specs. Cooling should be fine as wel However, will the motherboard in the dual Nehalem Mac's run Westmere processors? Does the BIOS need to be upgraded? Would a 3rd party motherboard run them instead?I'm gathering no one has done this yet.

Mac Pro :: BSEL Mod (Xeon Overclocking) Failed - Any Observations?

Mar 25, 2008

I followed the instructions here: [URL]. To do the BSEL mod. My (previously 2.0 GHz) MP booted up after brain transplant - hooray. Eight-core rendering in Cheetah, no problem. However the chips seem to be running at 1.86/1066 (According to Marcel Bresink's Hardware Monitor). If I somehow got the procedure wrong (wrong pin covered, say), should the chips be running at all? If I got the procedure right (correct pin covered) then what are the possible explanations for it not working?

Mac Pro :: Refurb. 2.93 8c Nehalem Or 2.4 8c Westmere?

Sep 19, 2010

m having trouble deciding between these two models. Might get the 3.33 Ghz 6c Westmere but leaning towards the 8c models. Why is the 2009 Nehalem faster? The guy at the Apple store was suprised by that also. Are there any changes in the 2010 2.4 8c Westmere from the 2009 Nehalem model?I will be using it for intensive music software (Prottools, Digital Performer, East West, Symphobia, Vienna Symp Inst. All web and graphics software (Photoshop, Flash, InDesign, etc and Astronomy programs)

Mac Pro :: New Barefeats Tests For Nehalem

Mar 11, 2009

Looks like the 2.26 is doing better after all. Some users have even gotten Cinebench scores for the new 2.26 like: 3142 (single) and 20,138 (multiple) reported here.

This free benchmark app uses real world code from Cinema 4D to render a sample project. It stresses all available cores. In the case of the Nehalem, hyperthreading fools the app into thinking there are 16 cores on the 8-core models and 8 cores on the 4-core models. The graph below shows the Cinebench rating for "Multi-CPU" render test.

It's not only multi-core aware, but it includes some memory tests which explains why the Nehalem based Mac Pros beat the older Penryn based Power Macs with higher core frequencies. The graph below shows the overall 32-bit score.

There is also a 64-bit version of Geekbench. Fewer results exist for it since, for some unexplained reason, consumers will gladly spend thousands for a new Mac but resist purchasing a $20 serial number in support of a starving Mac developer.

Can you upgrade the processors in the new Mac Pro's in the future if you choose to?

I have seen a couple people mention to but the 2.6 for now and upgrade them in the future when the price of the processors drops.

As titled, will there be any switch to make the single cpu working on dual cpu board, OR no way, that I need to put two? Or it's even simpler just boot the machine with one cpu left on board. Since putting 1 cpu save lots money for me.
