Pros: The latest generation processor available for the Lga 1366 platform. These processors tend to overclock between 4.0-4.4 GHz. I've got mine at 4.6 GHz with 24 GB memory on the internal memory controller (imc) . It has 6 cores and 12 threads of processing power. Mine also scored 1106 on cine-bench with an overclock of 4.6 GHz. Cons: Might not be compatible with every LGA 1366 motherboard. I had to update the bios on my Sabertooth X58 but after the update there were no issues. Other: Make sure to have decent cooling because this puppy runs hot and if you're running 24 GB ram or more then get an aftermarket spot cooler for the north bridge on your motherboard. My specs with this CPU: Xeon x5690 4.6 GHz, Motherboard: ASUS Sabertooth X58, Ram: 24 GB Corsair Vengeance DDR3 1600 MHz.

My 2009 Mac Pro Tower wouldn't boot up after installing these CPUs. Had to order another set, and when I installed the other set, and they worked beautifully! The set you sent must have been defective, or perhaps burned out.

I'm using a Dell XPS 435/9000 motherboard that initially had a X58 earlier Gen i7 which is a 4 core CPU and this Ebay X5690 is a 6 core so I think the gaming has improved a bit. It's very stable and reliable. I'm satisfied. Though I do think that my system would benefit on more performance if I'd re-install windows in UEFI mode, not DOS which I'm still reluctant to do as I'd either lose my data or rely on a back-up that I personally think reduces quality when transferred to & fro local, cloud and back to local drive (just my personal concern) so when I do, it will be a clean install.

I recently got a mac pro 5,1 cheaply with the stock dual 2.6 procs and someone suggested I upgrade it with 3.46's, so I went ahead and gave it a shot. I've done computer repair work in the past but this is my first time upgrading a processor in a mac pro. This model of mac pro isn't terribly difficult to upgrade, but it does take some time and might be a little intimidating for the new guy. You also have to do a reasonably good job with the heat sink compound or you could damage (overheat) the processors. There's a few videos online on youtube that show recommended ways (patterns) to apply the heat sink compound on procs like this so you don't get air bubbles, overflow, or incomplete die coverage. One thing to keep in mind is that some mac pros are set up to mount procs with the metal plate on the proc ("capped / lidded") and some are not. ("bare die") This will slightly affect the height of the heat sink. If that was all that was being cooled, it wouldn't matter. But the mac pro has a row of other chips (memory access I think?) that are also cooled by the heat sink, so if you change the CPU height, you have to account for the change in height. These procs are capped, so if you have an older mac pro with UNcapped procs, you will need to "shim" a little bit of height on the other chips in the row by the processor so they still get good contact and stay cool. So check in advance before you upgrade that you either have the same type of proc, or that you are prepared to keep the side line of chips cool too. I didn't have this issue because my mac pro's stock procs are capped, but if you do and don't adjust for it, you'll overheat the side chips on the CPU card and might have to replace the cpu card. Observe reasonable antistatic precautions too so you don't damage your new procs. This seller quickly shipped the procs, and they arrived in a small padded envelope, with the pins in soft foam and with foam wrapped around them, I'd call it well-packed. They were easy to unpack though. They were used as advertised in the listing, but the caps had been well-cleaned of any old heat sink compound, and all the pins looked perfect. They did a great job there of cleaning them up before sale. I've had them installed for several days now and they're performing great. 2.6 to 3.46 is a 33% increase in clock speed, and my benchmarking (geekbench) shows about a 25% increase in performance, which is about what I was expecting to see. I used some of my regular isopropyl alcohol to clean off my heat sinks when removing the old procs. The seller included some little packs of heat sink compound also but it was thicker than I'm used to using. I actually ordered an Arctic Silver kit of proc and cleaners from another seller, but he goofed and only sent the cleaner and not the compound so I had to make do with some thermalcote I had on hand, and it seems to be working fine. I suggest using a pattern closer to an "X" than a round dot when applying the compound to such a large cap, as the compound will spread out to the sides before reaching the more distant corners and you'll get compound spillage over the sides if you use enough to make it out to the four corners. Use a non-conductive compound if possible to reduce the risk of a spill causing a short. Try to avoid using too much, but absolutely avoid using too little, and definitely don't use a pattern that could leave an air bubble. Read full review

On an Asus P6T Deluxe V2 it works when BIOS is updated to 12.02, otherwise it will not boot up at all. Flash bios before installing! Very easy to do inside the BIOS, see several online videos and manuals. I cannot answer for any other X58 systems, but I'd guess always ensuring latest BIOS is just the best way to go.

I have installed these two in a Mac Pro 2009. First I de-lid them and it's not that hard with the right tools. Then I removed the old ones, cleaned the heatsinks and installed these ones and started it u, works like a charm! NOTE! - All the words about not to tighten the heatsinks too hard, it's just a fuz in the air! When you tighten the heatsinks just remember to do it diagonally and until it stops, the screws can just go so far. Good luck and make your Mac Pro as new again!
