|2006 Mac Pro Clovertown (Quad core) CPU Swaps Revisited|
|It's been years since someone wrote about a 1st gen Mac Pro CPU upgrade (socketed chip swap), although someone a few months ago asked about that. (FYI - since this post on July 10th, there's been other 2006 Mac Pro CPU upgrade reports including 3GHz X5365s (Clovertown Quad-Cores), low-cost (bought used) 3GHz 5160's (dual-cores) and even using Xeon L5320 (low power, 1.86GHz) Quad Core CPUs) The CPU prices this reader paid are a bargain compared to the original list price of the 5355's (and current pricing (appx $1000 each) for Xeon X5550 ("Nehalem") 2.66GHz CPUs used in 2009 Mac Pros). Googling/ebay searches for Xeon X5355s showed the lowest new prices ranged from appx $425 to $472 each - ebay had several listings of HP or Dell service parts and one listing for used (2 avail) X5355's at $247.83 each "buy it now" price. (Prices may or may not go down on these over time and the supply may dry up eventually.)
"Gen1 Mac Pro with 2 x Xeon 5355s (8-cores)
I purchased 2 Xeon 5355s (2.66Ghz/8MB/1333/Quad-core) off of eBay for $300 each (bought used he later said), and installed them in my Gen1 Mac Pro. (And he late wrote he sold his used 5150's for $212 for the pair to offset the cost of the 5355s.)
It was a drop in replacement - no software reinstall or compatibility problems of any kind. CPUs are humming along at 91 degrees F (idle) and get up to about 130 degrees maximum when pushed VERY hard with Handbrake. Mac Pro fans and heatsinks were apparently already made for these, as the Pro has no problem keeping them cool.
Speed increase is just about linear with Handbrake versus the 2.66Ghz dual-core 5150s they replaced. Sunspider benchmark on Safari 4 / 10.6 beta with 8 cores is 400 ms (557 on Leopard)! Skype 640x480 video is 5-6% CPU utilization under 10.6. HandBrake h.264 conversions are smokin at 175 fps.
Upgrade results - 9 out of 10, only because the CPUs are not natively recognized in 10.5.7 or 10.6 beta. But I found a CPU utility (AboutThisMac) that fixes that issue nicely.
BTW - I had someone write about doing this CPU Upgrade + 32GB of ram in his 2006 Mac Pro - I suggested he total up the cost of all upgrades and consider what the Mac Pro may bring used to see what the total $ (from the sale + what would be spent on upgrades) would buy as far as a later model (new, used or refurb) Mac Pro w/EFI64, PCIe 2.0 slots, faster ram, etc.)
Back in August 2006 I was sent some screenshots (from a hdw developer) on a 1st gen Mac Pro with swapped in 'Clovertown' Quad-Core CPUs (worked fine/PNP) but that was before the CPUs were officially released and I didn't post them at his request. (I still have the folder of those screenshots here.)
[FYI Several readers asked about a guide to upgrading their 1st Gen Mac Pro's CPUs - here's a link to a Youtube Video guide on Processor swaps in an early Mac Pro (MacWelt TV - in german) and in mid-Sept. 2006 Anandtech posted an article on Upgrading the (1st gen) Mac Pro's CPUs. You'll want a 3mm hex wrench to remove the heatsinks - John said he used an Elkind 3mm hex wrench (9-10" long "T" wrench) he bought for appx $4 at ACE Hardware.]
And back in early Nov 2006 (still linked on Macs/systems page here) I posted a link to Cnet's article with some performance comparison of an 1st gen Mac Pro with original dual-core CPUs vs Quad core Xeon 5355 CPUs. (Socketed CPUs are a big plus - the intel-based iMac and mini models have had socketed CPUs also, but the 2009 Mini no longer does apparently.)

This is a maintenance release. The following items were ﬁxed and/or added:
VMM: fixed network regressions (guest hangs during network IO)
VMM: guest SMP performance improvements
VMM: fixed hangs and poor performance with Kaspersky Internet Security (VT-x/AMD-V only)
VMM: fixed crashes when executing certain Linux guests (software virtualization only)
ACPI: fixed Windows 2000 kernel hangs with IO-APIC enabled
APIC: fixed high idle load for certain Linux guests (3.0 regression)
BIOS: properly handle Ctrl-Alt-Del in real mode
iSCSI: fixed configuration parsing
OVF: fix potential confusion when exporting networks
OVF: compatibility fix
NAT: fixed crashes under certain circumstances
3D support: fixed dynamic linking on Solaris/OpenSolaris guests
3D support: fixed incorrect context/window tracking for multithreaded apps
Shared Folders: fixed loading from saved state
Shared Folders: host file permissions set to 0400 with Windows guest
X11 host and guest clipboard: fixed a number of issues, including bug #4380 and #4344
X11 Additions: fixed some issues with seamless windows in X11 guests
Windows Additions: added VBoxServiceNT for NT4 guests (for time synchronization and guest properties)
Windows Additions: fixed version lookup
Linux hosts: workaround for buggy graphics drivers showing a black VM window on recent distributions
Linux hosts: fixed typo in kernel module startup script
Installer: support Pardus Linux
Solaris hosts: several installer fixes
Solaris host: fixed a preemption issue causing VMs to never start on Solaris 10
Solaris guest: fixed mouse integration for OpenSolaris 2009.06
Windows hosts: fixed high CPU usage after resuming the host
OVF: accept ovf:/disk/ specifiers with a single slash in addition to ovf://disk/
Fixed a settings file conversion bug which sometimes caused hardware acceleration to be enabled for virtual machines that had no explicit configuration in the XML.
I've added a FYI/link on v3.0.2 to the previous page of Mac owner reports on VirtualBox.
