    Hello!
    Cant seem to get me clock stable, it will BSOD in Intelburntest grr.

    I wonder what it can be as I have tested the Ram in Memtest86+ with your suggested settings, test 2 in 10 min and test 5 over one hour with no error!
    Test 2 and 5 passed over 30 passes each!

    And its stable in OCCT default 2 hour test but in Intelburntest its a no go.
    So it may be as ppl say that that program stress your comp the absolut most. im getting like 77degre in it but in Prime95 I only get 67degre as most with Hardwaremonitor!

    And it doesent matter if the MCH voltage is set at 1.2 - 1.3 or 1.4 so thats probably not the problem then and my timings seems okey so what can it be.

    I havent played with the MCH and CPU skews as you mentioned yet but they shouldent be the problem you think ?
    And what are the exactly do, will I get some more performance of my ram if they are set lower then default ?

    Best Regards

    77 degrees? What is showing you this temp, and what version is it. And is that core temp or CPU temp?

    That may be why Intelburn test fails, it is too hot.

    I cannot advise you about the rest of your questions as I do not know what you are now using for settings and would like to use instead.

    Yes, lower then default will be better, if you ram will do it and be stable. And that applies only to certain things, some lower will be worse

    From the horses mouth (OCZ)

    The importance of tRFC and 4/8GB of memory - OCZ Forum

    I have 2 x 2GB OCZ Nvidia SLI edition PC6400 and was trying a small/medium overclock on my GA-P35C-DS3R recently. This setting on Auto in the bios (TRFC) was reading 46 which should have been set higher by the board if the SPD has been updated as per the OCZ link above.

    Anyway after reading LsdMe's guide, I raised the TRFC to 56. As per the above OCZ link, DDR voltage can often be reduced too (as i found). I don't know yet if raising the value has impacted that much on performance but it has given rock solid stability in overclocks - ie checking with Memtest V2.01.

    Ya, I do not often speak out of turn. Some will do fine with less then 52, but it all depends on the brand of sticks, the IC chips used in them, and the overall choice of all other settings, speeds, and voltages in use.

    Any 2x2GB 52-62 is a good starting range, starting with 62 and working down. Some get to 48 and still remain stable, others can do 50. In the end, some brands, IC Chips wont be stable under 52-54. So that is why you always see my give ranges

    Gigabyte boards are not OEM boards, and for sure need to have as many things manually set and tweaked in the BIOS. Unlike a OEM board which things will be set/locked high or locked in a high AUTO setting with POOR performance, but stability that a OEM should provide

    Hello!

    I backed it down a little and have it at 3.2Ghz now as 77-78 degrees seems way to high and my temp do not get over 70 degrees now, hovers at 67-69 MAX in HWMonitor, of course it's the Core temp as im not that stupid to look at the CPU Temp and I montitor it with the Latest version 1.11.0 with IntelBurntest as it push the temps way higher then Prime95 does!

    BTW thanks for the ups obout the TRFC setting VorLonUK.
    I set it at 54 now just to be safe then :)

    My settings now are with my Q6600 and OCZ PC2 6400 800Mhz Reaper 2*2GB on P45-DS3R!

    Ahh, you should have also mentioned Burntest (If you did I guess I overlooked the test or forgot that is what you was using) as it DOES give far higher temps then OCCT, Prime, or Orthos, which I had likely thought you was using when you mentioned 77C as your Load temp.

    But either way load temp of 75+ is hot for sure, But I would not expect that with Prime or Orthos so much unless you did have a bad mount or really bad cooler, or WAY to much volts. Sounds like you got it better now

    You can bring down Static tRead for sure a few, and likely MCH voltage as well

    Oh well sorry mate I forgot to mention that :-/
    Yepp IntelBurntest push up the temps to crazy levels and I dont know if you really can go after that as most ppl use as you say Prime95/ OCCT or Orthos, I used Prime95 25.6 build 6 and the temps are 10 degress lower or so then in IntelBurntest!

    Im sure no game in the world can even push up the temps as high as with Prime so maybe its best to check temps with that and then my temps are under 60 degrees. IntelBurntest may only be okey to use as a quik test but you should not use that as a baseline as it push the temps to the extreme. what you think, I guess you only go after OCCT / Prime temps ?

    I memtest the tRead steady at 48 so I can probably set it at then or test it out even lower if I found the energy, but im starting getting tired of all this testing hehe!

    BTW, Thanks for the reply once again :)

    Ya, I think Intel Burntest has it's +'s but high heat is for sure a Negative. I do like the quick test letting you know if it is stable or not.

    Ya, I use Orthos only for my testing within windows. And of course PCMark05, SuperPi, and for GFX 3DMark 06, FurMark, and LightSmark is what I use.

    tRead at 48? WHAT? I think maybe a typo Static tRead Value suggested ranges is 5(7-10)12

    Ooops damn I mixed it up im afraid as I was thinking of the trfc and not the Static tRead hehe.

    Okey so I can test it at 5 and if that's not okey I have to jump to 7 if I understand you corect?
    So I cant try it out at 1+ as this way if 5 is to tight 6-7-8-9 etc ?

    One have to set it at 5 or 7 if thats not okey then 10 and if thats no go then 12 ?

    BTW! Is it the same with say the trfc value, start for ex at 48 as I said it seems stable and then I can work my way down for 47 and then 46 - 45 - 44 etc ?

    Maybe a little bit stupid questions but just to be sure :)

    Thought so!

    Ya well 5 is likely not stable unless you are at stock 800Mhz, and then even normally it is not. 6-7 is usually safe from 800-900+, 6 may cause A HARD Fail and you need to clear CMOS, but maybe not.

    No, when I say something like 7-12, it can be anywhere between 7 thru 12. If I understood you right

    Ya, with trfc, too low will error out in memtest though and can also cause HARD FAIL.

    No question is stupid, except the one not asked
