    I've picked up an ASrock Extreme6 LGA 1366 thats got an i7-940. Was quite looking forward to doing something with this however was a little underwhelmed.

    Thats was until I discovered that I can put a Xeon in it to potentially give it a decent boost. Prices for all xeons are less than $50 from Ali Express but just wondering if there are any traps to look out for.

    My board's CPU support list says X5650, X5670 are supported but do I need to stick with these or is any Xeon in the X56xx range ok?

    Are any better overclockers than others?

    Any suggestions?

    I recommend the X5675.

    Well priced, the highest boost clock out of any Westmere-EP and the lowest TDP out of any Westmere-EP.

    I still use two daily in my workstation and they do everything I want including gaming and perform very well.

    Does it matter that is not on my motherboards supported CPU list?

    Probably not.

    X5698 is the best for clocks (4.4GHz stock) but only dual core. These are hard to find because they were only made for a dedicated application. These were insanely fast for their day but the lack of PCIe3.0 support means they fell behind first Gen E5s for most applications.

    If you can't find those, look for X5687/X5677 for 4-core and X5690/X5680 for 6-core.

    Thanks wwwww, in the end I went for an X5650. Would liked one of the above however they weren't available in Aus on ebay. Would have to go through ali express but who knows how long it might take to get here and want to get on with it. Could have got a 5670 but was more expensive for what looks to be a 10% improvement. The system is likely to either be used by me for testing or it might go off to someone who wants a cheap gaming PC so decided to keep the price down rather than suck every bit of performance.

    Hopefully it will be a nice boost compared to the i5-940.

    Appreciate the reply, I found it very interesting and learnt a bit.

    I've never once even come close to saturating the pcie bus either via gaming or benchmarking running a 980Ti.

    You know some people use PCIe slots for other things right?

    I'm also booting an m.2 SSD via a pcie > m.2 adapter and getting impressive transfer speeds of about 1.4k/sec under pcie 2.0 x4. Sure, not as fast as the 1.8k/sec that newer rigs are getting, but still impressive considering the age of the tech, and in the real world the difference wouldn't even be perceptible in 90% of all cases.

    90% of your cases. As I said, PCIe slots are usually used for other things. I use the E5 v2 platform for my server. It has 240 PCIe-3.0 lates and is starved for bandwidth just to handle the storage and the IB interconnects. There's a reason this platform has so many PCIe lanes and it's not to run your graphics card and consumer SSD.

    I'm not doubting this and never stated otherwise. However, for general consumer based usage the platform still has plenty of life with more than respectable performance. I also run a hardware raid card flashed to IT mode for SATA3 via pcie 8x and I have no problems, performance is fantastic. The only thing I'm lacking is USB 3.0 and that's only because I've run out of pcie slots.

    I have a newer machine, but TBH I rarely use it as I have no need to use it. Most of the time the Daughter plays games on it.

    Its all a bit over my head. Anything amongst it I need to be aware of to build a basic gaming machine?
    I'm expecting it will still beat an i7-940 and hopefully get close to my i7-2600k which is still holding its own.

    As the ex owner of a 2700k, an overclocked x5650 will game just fine.

    My system games just fine running two x5675's and a 980Ti, and it's not overclocked and I'm running most of my games under Linux via Proton and DXVK.

    Lol Cobalt765, dig up some of my posts. Start here.

    I am a massive fan of Intel's HEDT (X58/X69/X99) platforms and have owned 30+ X58 boards blah blah blah.

    To answer a few of your queries:
    - A decent X58 setup with an overclocked hex-core Westmere EP chip will smash an i7-2700K
    - Unless you're trying to get the absolute max from your system, go an X5650 every time, they were $22 posted on eBay AU at on point
    - They're all the same silicone, the higher-end SKUs are just better bins
    - I got my X5670 to 4.5 24/7 stable back in the day (NH-D14)
    - My current X5650 sits on 4.0 under an NH-U12 and I've seen them do 4.4 under AIO water. So there is very little benefit in the more expensive chips
    - In my experience, if a motherboard can run some Westmere-EP chips, it can run all Westmere-EP chips.

    Don't be underwhelmed by X58. This shit rocks, it just takes a little bit of tinkering :)

    Also, while I have never used your board (which is rare with X58 lol), most of the USB3 / SATA3 on X58 was pretty shit. So if you want decent storage, go a 950 Pro with an m.2 adaptor, or when I can't get a 950 Pro, I sometimes use an mSATA add-in card with a reliable chipset and stick an mSATA SSD in it. Not as fast as NVMe of course, but more reliable than X58's on-board SATA3 (in most cases).

    Also look into whether or not your board supports RDIMMs (Registered ECC DDR3). Some X58 boards did, and AsRock boards have a history of supporting it when they probably shouldn't (My X79 Extreme9 was running 3x16gb sticks cos the other 5 slots were faulty :lol:)

    RDIMMs are a cheap, easy way to get a decent amount of RAM for HEDT platforms.

    Again unless you're trying to eek out every possible inch of performance, but good luck getting 6x4gb DDR3-2000 or faster, and even then, good luck getting it to run at decent speeds if you're overclocking the X5650 :lol:

    Better off (that I have found) to go for a bigger OC on the CPU and stick with generic 1333 sticks.

    Just my 2c :thumbup:

    (Still running a P6TD Deluxe w/ X5650 @ 4.0 and 3x4gb Patriot 2000, and a P6T Deluxe w/ i7-960 and 3x4gb Corsair 1600, both still very solid rigs)

    I'm really happy with my i7-2600k combined with my GTX1060 however do you think that I might even consider keeping this X58 for myself?

    Certain Kingston HyperX m.2 SSD's also support legacy mode for booting under x58, that's what I use.

    Also, using an LSI 9211-8i flashed to IT mode for sata3 passthrough is easily as good as any native solution. I do this and it works well.

    I have no plans whatsoever of retiring my x58 (Intel 5500 chipset for NUMA) any time soon, damn things a tank and showing no signs of slowing down.

    Had a go at overclocking the i5-940. Learning a bit before my X5650 comes in. Its never run that cool hovering between 40 and 50 degrees at idle. When I got an overclock of 4.0ghz, at 1.35v, temps soon went soaring when I started Cinebench R15 and hit 100 degrees before I quickly aborted.

    The CPU cooler is a Thermaltake Jing which reviews aren't the best however I don't think it should be that bad. One of the spring screws on heatsink wasn't an original so I'm wondering if perhaps there isn't a nice even fitting of heatsink on CPU. Any ideas? Do they normally run this hot or is there another issue.

    That's not right, even in the day when I had an i7 920 @ 4Ghz+ I never had temps like that. As stated, I'm running dual X5675's @ stock in a Dell workstation and right now I'm idling at 32 degrees and hit 80 degrees max at full load.

    You either need a better cooler or you need to improve your case cooling.

    Thanks flu!d but I don't think it's case cooling due to going up that quickly. Any air coming out it's also quite cool. Might need to put my cm212 in to test.

    If air is cool and cpu is hot, the heatsink is not making good contact.

    Got my X5650 through today and got straight to work. The above cooler must be bad as temps are much lower with CM212.

    The results were really good against my i7-2600k which I'm comparing against. X5650 @ 4.0ghz, i7-2600k @4.3ghz
    Pass mark 8020 vs 6844 - 17% better
    Cineench R15 - 914 vs 772 18% better.

    My question is how does this relate to real world use? Will it really improve getting frames or are the extra cores just coming out in front for synthetic benchmarks. Main games I play are Assetto Corsa Competizione and F1 2019. I do have other games with built in benchmarks but what is the best way to test? Lower the resolution and/or settings or just run with max graphics like I'm used to?

    Trying to decide which to keep for the long term.
