    lol no. The 9.5 multi of X5460 is plenty, it's just that I found an older C0 stepping I had to be more limiting than I previously thought - 45nm chips run way hotter than 65nm ones volt-for-volt. So I ordered E0 awhile back.
    My X5460 C0 which did 4Ghz at 1.38v will be going for sale soon.

    Will they work? Maybe, maybe not.

    Just because they work in one system does not mean that they will work in an identical or similar system.

    The settings look reasonable, but the odds are against you that copying someone's settings will be stable, let alone allowing your system to boot into windows.

    I copied the AnandTech "EP45-UD3P Finest" review settings for the 8GB Q9550 and my system barfed while posting.
    It (almost) never hurts to try.

    Keep in mind that there is a specific procedure that needs to be followed why tweaking the MCH Reference and/or Cpu Reference settings.

    From EP45-UD3R E8500 overclocking

    The general recommendation is that VTT should be set at least 0.05 - 0.10 volts lower than Vcore.

    With LLC enabled, you are able to run with Vcore somewhat lower than the Vcore setting when LLC is disabled.
    I've seen a few stable setups running at higher than 4.0GHz where VTT was closer to or equal to Vcore.

    You might be able to lower these voltages by tweaking MCH Refenence voltage.
    The proper way to do this is:

    1. set VTT = 1.20
    2. modify MCH Reference to the new value
    3. set VTT back to the desired value

    It's best if you include this information in your bios settings as:
    MCH Reference -------- 0.760V ------ : [xxxx] set to 0.7?? at 1.20 VTT

    where xxxx is the value displayed in the bios after you have re-set VTT back to the current setting

    Most extreme C2D overclocks that tweak MCH Reference use settings lower than 0.760 (with VTT set at 1.20), such as 0.740, 0.720, or 0.700.

    FYI, this post shows Intel's guidelines for the P4 chipset family. With 1.40, you are 6% over the recommendation, which should be safe for now.
    I recommend extended stress testing with your current setup. Short term use with your current settings should be fine.
    Post your current bios settings and screen-shots after you have completed testing.
    With your quad core cpu, you will probably want to increase MCH Reference or Cpu Reference but it's possible that lowering either of these settings might help.

    Many of the better overclocking guides say that tweaking either of these settings is often needed with FSB = 475MHz or higher. As I recall, Anandtech and others have stated that quad core processors often work best with a 70% ratio, for example 0.760 divided by 1.20 (the standard settings) is 0.6333 or 63.33%.

    Some people complain that mathematics makes their head hurt.
    If you're one of these, I can't help you.

    Question Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

    Well I took a look at the screen and my X5460 is getting HOT!
    I wouldn't be surprised if my PC has shut down when I check it again tomorrow.

    In the meantime I wonder if you can help with another query...

    I'm about to return my USB 3.0 PCIe card (Inateck PCI-E to USB 3.0 2-Port PCI Express Card and 15-Pin Power Connector, Mini PCI-E USB 3.0 Hub Controller Adapter, with Internal USB 3.0 20-PIN Connector - Expand Another Two USB 3.0 Ports - [ Include with A 4pin to 2x15pin Cable + A 15pin to 2x) and purchase a new one from the same vendor that does not require a power connection (Inateck 2-Port PCI-E USB 3.0 Express Card, Mini PCI-E USB 3.0 Hub Controller Adapter, with Internal USB 3.0 20-PIN Connector - Expand Another Two USB 3.0 Ports for Windows XP/7/8/ - No Additional Power Connection Needed: Amazon.co.uk: Computers & Acc).

    I thought I would also purchase a splitter cable for my fans and was wondering if it'd be worth it to spend 1 more and get this 4 pin version (StarTech 12 inch 4 Pin Fan Power Splitter Cable - F/M: Amazon.co.uk: Computers & Accessories) or a generic 3 pin version (http://www.amazon.co.uk/Generic-Powe...splitter+cable) I currently have my CPU cooler fans connected to CPU_FAN and SYS_FAN 1 and my case fans connected directly to the power supply. I thought if I used the splitter for my CPU Cooler fans then I could use the SYS_FAN 1 supply to monitor my Noctua case fan.

    Do you think it's worth it?

    Have you tested your existing usb3.0 add-in card with it installed in your EP45-UD3P?
    It should have somewhat better throughput compared to the P35-DS3L's pci-e bandwidth.

    My 3TB Toshiba/Canvio's usb3.0 performance is reasonable (i.e. up to ~100MB/sec) with my P35 and P45 motherboards, but my Samsung 830 performance connected to the same add-in card is terrible, probably because of the docking station that connects to the add-in card. Have you tested your external hard drive's performance when it's connected to the EP45-UD3P? Don't expect any miracles, but it should be somewhat better than the P35's performance.

    When you use a fan splitter cable, only one yellow (rpm) wire should connect one female connector to the cable's single female connector. It appears that having both male yellow wires connectors to the female connector causes errors with the reported fan speeds. Keep in mind that you can use the slow sys_fan2 motherboard connector (or any other fan header) to monitor a fan's speed when it is powered by your power supply.

    With some cable ends, it isn't very difficult to remove one of the yellow wires.

    Maybe you can find a good local dentist who is proficient with a soldering iron who can perform some fan cable splitter surgery.

    note: With the cpu fan header there is a difference in fan speeds when you select PWM using voltage versus using true PWM.

    Several options:

    Question Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

    It seems I was a bit tired last night as non of my fans have the PWM function anyways!

    I don't have access to a soldering wire and I don't think there's a single cable I can purchase that will be powered by the power supply and also allow connection to the SYS_FAN 2 connector to monitor the RPM... So I'll stick with having my cooler fans connected to CPU_FAN and SYS_FAN 1 and my case fans connected to the power supply for now.

    I haven't tested the PCIe card in my EP45-UD3P yet, but I am considering changing more for the convenience of not having a power cable attached as there's a chance it would disrupt the airflow (correct me if I'm wrong there).

    Well my system passed 10 hours of the Large FTTs but it was very hot - so much so that RealTemp displayed 'HOT' for core 1 when the other cores were ok.

    Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock-10-hour-prime95-ftt-pass-3-61-jpg

    (TjMax = 85C)

    Do you think it's ok to go on and run Small Ftts or are the temperatures a concern?

    You have Thermal Monitor 2 enabled in your bios so the worst that should happen is that your cpu will throttle down to lower the cpu temperature. This might affect the Prime95 test results, but so be it. I need to keep reminding myself that you have HWiNFO and RealTemp set to report core temperatures using TjMax = 85o(C) and not to use the "normal" 100o(C) value when computing the temperatures.

    I'm curious what TjMax value SmOgER is using with HWiNFO.

    If I were you I would be running much shorter LinX tests, for example no more than 5 loops using 2048MB of memory.

    As I recall your Antec P82 computer case is a very quiet case, but it does not excel in providing adequate airflow and internal cooling for systems that generate a lot of heat.

    If you need to splice any individual fan cable wires, do a web search using: western union splice and look at the pictures and read the instructions. You should also use the correct diameter of heat shrink tubing to insulate all wire splices. Don't use regular electrical tape to insulate the wire splices as the heat in your computer case will cause the tape to unravel sooner rather than later.

    • You will need a splitter cable that has two male connectors, one for each fan and two female connectors.
    • One yellow rpm wire needs to be disconnected from one of the male cable ends.
    • One female cable end should only have the yellow rpm wire connected; the red and black wires from this female connector must be removed before you plug this altered female connector to the motherboard's cpu fan header.

    I just noticed that there is a PSU_FAN as well as SYS_FAN 2 - I'll try both of them and see what speeds they report for my Noctua case fan.

    Small FTTs still going - high temps again, I did a sensor test in RealTemp before the Large FTT test (don't really know if that will have made any difference at all...

    Sys_Fan2 is a PWM fan but it normally doesn't deliver full power.

    With Sys_Fan2 my 1600 rpm fan only spins at ~ 600 - 700 rpm.

    The Sys_Fan2 speed increases somewhat after the interior case temperatures rise a significant amount.

    The remaining 3 pin headers will deliver full speed and the Cpu_Fan can run at full speed if you disable PWM mode.

    When you're done with the current Prime95 test, see if disabling LLC and increasing cpu vcore somewhat has a positive effect on cpu core temperatures.

    Page 24 in the EP45-UD3P user's manual shows the location of the four motherboard fan headers.

    Thumbs up Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

    7 hour small FTTs passed :):

    Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock-7-hour-prime95-ftt-pass-3-61-jpg

    (TjMax = 85C)

    Going to test the USB 3.0 card and use the CPU_FAN connector before increasing CPU vcore and disabling LLC and trying for a higher overclock, running blend overnight, possibly after a 5 loop 2048MB LinX test.

    I ordered the cable-free USB 3.0 PCIe card and if the performance is the same, I'll return the older model :)

    Any idea what overclock I should aim for? I'm guessing 3.8GHz but not sure what kind of vcore increase this will require...

    Smile Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

    So I installed my USB 3.0 PCIe card and ran some benchmarks:

    Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock-usb-3-0-benchmarks-pcie-power-cable-png

    These are much better than my previous system (Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock) so I'm pleased :) Just hoping that the new card will have the same (or better) performance when it arrives.

    I also connected my Noctua case fan to the SYS_FAN 2 connector and HWiNFO is strangely mis-reading the RPMs as ~16,000 :/ Not sure why this is but hopefully it won't be a problem.

    I'm now about to try running at 3.8 and see what happens - If all goes well LinX screenshot to follow :)
