    Is def 6GB kits

    Yfrog - memv

    Though not sure why it doesnt say PC3-12800?

    One came from here - http://www.ebuyer.com/product/152640
    and the other from here - https://www.overclockers.co.uk/showp...odid=MY-169-CS

    Same as 1066 DDR2 being overclocked 800Mhz, DDR3 is just overclocked 1066Mhz.

    Ya, it is 6GB for sure, that kit is anyway :) Is that the one that has the 3G in the name, or it that the one your friend has?

    Sorry for all the questions - Just like to know what im changing / what things do etc etc. I have read up alot regarding values for different things in the bios as im new to overclocking however the problem is everyone has different stories hence why i thought id ask you directly regarding some of the above questions. Hope this is ok and sorry to be a pain.

    Edit: Maybe i should point out at this stage that im still using F2 bios. The other pc is using F6Test from Hicookie though i havent changed mine yet as i wasnt sure which one was the best. Just thought id mention this incase it was worth noting.

    No problem!

    Uncore Frequency .......................... 3800mhz (is set to AUTO as above) << Set manually, 2x memory multi or above. Often at high Blck 2x +1 or 2x +2 is better (I use 2x +2 most often). Auto is using x19 which is too much [What is 2x2? Sorry this uncore freq confuses me..In bios doesnt it say things like 2:8 2:10 etc? Need to look again to check.....]
    What 2x +1-2 means is this. Uncore should always be at least 2 x your memory multi, or above. So 2x +1 or 2x +2 is often used. In the BIOS the values are shown as x16, x17 and so on.

    Performance Enhance ...................... [Turbo] << I find Extreme to be most stable ok to leave on turbo for now? I ask as im not sure what this actually changes
    Yes, you can leave if you like, I think it will be fine

    DRAM Timing Selectable (SPD) .......... [Auto] Expert, set each channel main timings one by one What too? 9-9-9-24 im guessing? Just want to be sure :)
    Yes 999-24 1T for now

    Load Line Calibration ................. [Standard] Level 1 I was reading in google that setting this to level 2 is bad for the cpu though cant seem to find out why though again im not 100% sure to what this does. I have read using level 2 is really good for increasing overclock potiential of the chip though at the same time isnt a wise thing to change?
    Well Level 2 does increase voltage, some like it some do not, just personal preference I suppose. What it does is adds to Vcore under load, a lot sometimes. I do not like it myself, that is why I suggest Level 1. Level 2 would not increase an overclock, it just adds more voltage under load, something you can do manually and control by setting value manually and use Level 1 to keep Vdroop at a minimal amount

    QPI/VTT Voltage 1.150v ............ [Auto] (did try at 1.315v) << This will need to be 1.32-1.4+ depends on your CPU and memory timings, but auto will use much more than you would that is why it works but 1.315 did not for you.

    Yes, often you can see it on the BSOD page before the system restarts, or in the error box vista/windows 7 brings up after you restart if you tell the box to show you more details.

    0x000000124 More Vtt (124 in windows error message after restart)
    0x000000101 More VCore (101 in windows error message after restart)

    Re the above settings, i read that unless using crossfire/sli it was ok to leave the above on auto?
    Yes ICH ones may be fine in auto, but often times IOH will need to be increased. Sometimes auto will be ok for this though, if you want to test be sure to manually set the stock value otherwise Auto may increase it anyway. QPI Pll, stock may be ok but I find a bump to 1.2+ often helps much with stability

    hmm i feel rather stupid atm, isnt my memory multi x20? so twice that would be x40 uncore?? What am i working out wrong?

    So level 2 must be real bad for increased tempatures? I want to reduce mine, not increase them so will leave that alone in terms of level 2 ;)

    Right, ill be off to test then - Maybe ill even get a post bios beep again if im lucky :)

    Edit: Well i will do after i know what the multi uncore thing is properly and what setting to choose lol

    It is a case of 4 cores and 4 threads = a multi of 8 so x2 would be 16, hence why the +1/+2 would be the x17/x18 recommended setting? Is that how it works?

    Edit2: Well ive applied the above settings, still no flipping bios beep... does it only come on when its standard settings? lol - Will have to do some tests to see if i get the red warning screen on bootup, and stability compared to before.

    So guessing when alot of things are set to auto it could increase voltages which would increase in a BSOD? Suppose now i can start testing lower vcores again as last time i tried lowering this from 1.3000v id always get the BSOD though if im honest NEVER checked what error code it was and didnt have alot of settings in place so could of well been the VTT

    No, your memory multi is x8 from the above settings
    System Memory Multiplier (SPD) ........ [AUTO] << x8
    Ya, I don't like level 2. It can make your voltage jump high under load, for example from 1.35 under load if using level 1, to 1.42 under load if using level 2 with the same vcore set in the BIOS. So yes, temps would also increase highly under load.

    I am not sure what you mean by all your numbers here.
    It is a case of 4 cores and 4 threads = a multi of 8 so x2 would be 16, hence why the +1/+2 would be the x17/x18 recommended setting? Is that how it works?
    But how uncore works is easy, it just must be 2 x Memory multiplier (SPD), or above, above is where you get 2x + 1 or 2x +2

    BIOS beep? What do you mean? Is the system starting and posting? If so you can ignore the no beeps, could just be a bug in the BIOS. I don't even have a speaker connected because that annoys me, I only use them if there is an issue.

    Yes, if overclocking don't use Auto on things like Vcore, QPI/Vtt, Vdimm, CPU PLL. Rest may be fine in auto

    Ahh i see re the multi now :)

    Regarding the beep it dont bother me, the bios posts and loads so..... :) Need to turn off and on a few times to see if i get the red warning screen or not......

    Would i be right in thinking that the only voltages that affect cpu core temps would be the cpu vcore? if i never had the other settings done before this could well be the reason i was getting the BSOD, i hope. So if i lower the vcore now and test in prime95 hopefully it should be more stable than before and i can start testing to see how low i can go to reduce temps?

    Any other tips that i should be aware of? Thanks for all the help/advice and ill post here as i go along. For now, its time to power off, and see if it posts without the warning screen.....

    If you go into the MIT section of the BIOS after a reboot to windows and reboot again and do not see the red box you are fine so far.

    Vcore and QPI/Vtt are what will affect your CPU temps, HT will as well.

    Yeap, test and lower, test and lower, test and lower and so on until you are happy and stable.

    So is it just a case of lowering each one by one until i get a BSOD to work out the min voltage needed for the speed i want?

    Appreciate it more than you know - Top man :)
