    Well since we're doing things the right way I will take the cooler off and re-apply the TIM :)

    I will also change those BIOS settings.

    Here is a photo I took of my RAM re the timings:

    Also, you have a great eye for detail and I'm curious as to what information from CPU-Z misreported my processor in my first post?

    Look at the upper left cpu-z window where it says you have an Intel Xeon E5450 cpu.



    In another recent thread, there was a mismatch in the memory timings sticker on the module and the programmed SPD values shown by Memset and cpu-z.
    As I said earlier, I've never seen 5-5-5-12 timings; 5-5-5-15 or 5-5-5-18 timings are common.
    I was pleased when both of my higher end ddr2 memory kits with 4-4-4-12 SPD timings were stable with 4-4-4-10 timings with 8GB of memory.

    Take a look at the following air cooling review that includes the newer Noctua NH-U12S and NH-U14S coolers:
    The Best CPU Coolers: 10-Way Roundup - TechSpot September 6, 2013

    Both of the newer "S" models performed well and probably ran a few degrees cooler than the older "P" models.
    Typical results with a push/pull fan setup usually lower core temperatures by 2o - 3o(C).

    When you are applying a line of thermal grease on your cpu, with your motherboard and case in the normal vertical position in front of you, applying the TIM vertically (top to bottom) on the cpu is actually using Artic Cooling's "horizontal" line recommendation.

    That is a lot of information! It'll take me a while to try to take in the most important parts.
    I think you're right about the timings (ballistix sport tRas timing - Crucial Community) - am I running these at too high a voltage with the +0.2V setting?
    Also I returned the Startech card so have some amazon credit to play with - should I buy a different TIM or anything else?

    You can go crazy trying to find the "best" thermal grease and reading numerous reviews doesn't make it any easier. Unless you go with the Coollaboratory or Indigo Extreme TIMs, chances are there will only be a couple of degrees difference with many of the better TIMs. I've never tried either of these "exotic" TIMs.

    All the reviews of your NH-U12P cooler indicate that it should do better than your results so far. It takes a fair amount of practice to apply just the right amount of TIM, as too little or too much leads to higher cpu core temperatures.

    If I had to buy new TIM, the Noctua NT-H1 would be near the top of my list.
    You still have two older tubes of thermal grease to play with and they might be fine. Will they perform better than the AS5? I don't know.
    See if you can get some lower temperatures with the Arctic Silver 5. If you leave you system on overnight and turn it off and let it cool down completely every day, you'll help speed up the AS5 curing times which should lower your temperature several degrees more. You can easily do several heating/cooling cycles each day as well as putting a big dent in the required break-in time.

    Right now it looks like your cpu core temperature readings are about 10o(C) too high, at idle and when stress testing.

    Contact Crucial tech support and see what they say about the maximum voltage settings and the correct SPD timing values.
    Crucial.com - Contact Crucial support, live chat might be the quickest.
    Maybe they have a toll-free European telephone number.

    As I recall, the JDEC standard voltage is 1.80 volts and up to at least 1.90 volts. I didn't find any useful information at their web site.

    Sorry for the late reply... 6 days left til (hopefully) my last ever exams so time is getting precious!

    Here are the pictures of my (your) rice grain method test:

    and here are the photos of my second try (which I unfortunately forgot to take a pre-mounting photo of):

    Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock-rice-grain-real-jpg

    Am I getting there?

    The temps were 1-2 degrees higher with this one (43-44) but obviously not before the thermal cycles which should help cooling

    Think I might go and buy some more NT-H1 (one website said they're good for 2-3 years so don't know about my old stuff!)

    The amount of TIM in post #75 is good, even though the coverage in the corners isn't ideal.

    There is too much TIM in post #76 and this increases cpu core temperatures.
    I hate to see excess TIM buildup along the edges of the cpu

    The picture below is ideal.


    In Arctic Silver's picture below, the picture on the right implies that they feel that the coverage in the light red oval is correct.
    My approach is that better TIM coverage in each of the corners should help lower cpu temperatures a bit more.



    In post #72, Skinneelabs says that he used the "2 grains or rice method".
    He probably describes this technique in some detail somewhere on their web site.
    My best guess is that he uses two grains that are not too far apart and in the center of the cpu.

    Check out Best Thermal Paste Application Methods | BenchmarkReviews again and take another look at the two parallel lines method:



    "One of the fears I hear about most with this method is that air may get trapped in the middle. However, one look at the image below and I can safely dismiss this potential problem. After the cooler was lifted, I discovered that the two line pattern was able to reach all four edges of the CPU. It seems that this method could have some real world application if correctly applied.

    It took some additional cold tests for me to get the amounts correctly tuned. After the retest results (not pictured), the best ratio I found was using line lengths equal to the distance between the lines; or roughly 1/3 the width of the processor."






    and the "X" TIM pattern coverage:

    "Next up was the cross method of applying thermal paste to the coolers mounting surface. Since two lines worked well, perhaps overlapping them would have an improved effect? I have not personally used this pattern in my own systems, but other web sites have claimed that it can work."



    "After a few test applications, the image above is the best coverage I could get. Plenty of material covers the surface, but there are clear signs that too much TIM has reached the edges. Again, the disclaimer here is that this pattern might work for your setup, and every application is different. In my tests however, I wanted more uniform coverage and the cross method took some practice before it could meet my needs.

    In the image above my line length was too long, measuring 2/3 the width of the processor. With additional cold tests (not pictured) I learned that lines of the same thickness but only 1/3 in length did a better job and kept the material amounts in check."



    In the above picture I'd like to see less TIM buildup at each edge of the cpu.

    Your studies obviously come first, but you might want to take a brief break and try using your older tubes of TIM, who knows, they might work fine.


    Below are my RealTemp Sensor test results with the ambient temperature starting at about 16o(C) with:
    • cpu running at 2.00GHz ( 6 x 333MHz)
    • cpu voltage = Normal
    • memory timings all set to AUTO


    If you boot with similar settings and your cpu core temperatures remain the same this probably means that your sensors are stuck in the 40+o range at the low end.

    You could then run Prime95 Small FFT test for about 15 minutes and then see what your maximum cpu core temperatures are.

    I wonder if there is something with the 771-mod that is possibly causing higher than "normal" cpu core temperatures.

    Hey profJim!

    I haven't been home yet to do any more work yet but I posted on a 775 to 771 support thread on overclockers. One guy said my vcore was too high an another said:

    "Your Tj max setting in Core Temp is wrong and because of this it displays 15 degrees higher. Set this parameter to 85C".

    I thought I would run these by you before going ahead and making any adjustments... I guess lowering vcore and Tj max can't hurt, right?

    What's that old saying? A little knowledge is a dangerous thing.

    As I understand it, cpu core temperatures are computed by how far away you are from the cpu core's TJmax value.
    Rather than try to explain it (badly I might add), read the Real Temp - Documentation and you will see that altering the the TJmax value in a software program only changes the displayed value of the computed temperature, and doesn't change the actual cpu temperatures. If you want some additional reading check out the 2008 Intel IDF presentation. Page 16 starts the Xeon section in the document and your X5460 is listed on page 19 with a Target Tj = 85oC.

    Don't jump to conclusions as it is possible for each of our cpu cores to have a different Tj value.

    It's time to see if your system is overheating and throttling your cpu with 3.60GHz and higher cpu speeds.
    To protect your cpu, Thermal Monitoring should always be enabled in your bios.

    Maybe using the 771-mod to run your cpu in an LGA775 motherboard is causing the reported TJmax value to be to high.


    Happy reading.
