    Thank you. The reason is also that I have an Accelero Xtreme 280 mounted on my GTX 285. It keeps my GPU very cool and never goes above 55 C at 100% load running Furmark. Which means that the air that is blown into the CPU cooler when doing Prime 95 is not as warm as if it was the stock cooler at my GTX 285.

    I can actually mount 3 Scythe Ultra Kaze on this CPU cooler and run them all at 3000 rpm, in a push/pull/pull config, but the noise would be too much.

    Wow! 4.22 GHz on air with a C0 is impressive. I'm envious of your acheivement, way to represent the C0's. What's your QPI/VTT voltage set at?

    Impressive? Donīt know about that but I am able to do Bclk 205 x 21 = 4.3 Ghz on air but it takes a lot of voltages and it is not worth the extra electricity.

    When I run Bclk 201 I use 1.37 in QPI/VTT voltage and 1.66 DRAM voltage. Either my CPU or my motherboard has run into a wall at Bclk 205, because no matter what settings and voltage I use it will not go any higher.

    Your temperatures are very good even more so seeing you have HT enabled and you use a much lower CPU voltage.

    hey guys, did a ton of tweakin last nite. poul, i see you have your qpi and dram voltage above whats recommended. No trouble with it? im beginning to think this is what im stuck where im at which is 21x180 . I can boot to windows with 185 blck which equals 3.885ghz, but as soon as i open prime i BSOD. This is with vcore increases roughly 1.35 to 1.4. i dont feel comfortable crossing the 1.4 mark , let alone intels spec of 1.375.

    Of course nobody knows the long term effect when running above what is recommended, but I have been doing that since I bought the PC without any problems at all. I have seen people use above 1.70 DRAM voltage but again - who knows what can happen. I need to set vcore in BIOS to 1.40+ to be stable but it will show llike 1.392. Never had any problems - again do it at your own risk of course.

    About you BSOD when trying to run Prime95 - you most likely need to raise either vcore or Qpi/vtt. What does the error code say when you get BSOD?

    Look at the last numbers in the error code?

    Lsdmeasap posted this a while back:

    0X00000124 << Incorrect QPI/Vtt Voltage (To Much/Not Enough)
    0X00000101 << Not enough Vcore Voltage

    Now I will bet you see one of these when you run Prime95

    To anyone who is thinking about buying a new heatsink I can highly recommend the Thermalright IFX-14 CPU cooler. Mine is equipped with one Scythe Ultra Kaze running 3000 rpm and a Scythe Flex 1600 rpm (I think but can not even remember anymore) - facing upwards towards the bigboy fan outlet in the top of the case in a push/pull configuration. I have another Scythe Ultra Kaze as well but I have not yet bought something to control its rpm and running 3000 all the time was a bit too loud.

    My temperatures are quite low considering a voltage of 1.38 (+ something) in BIOS, which gives me 1.376 when reading CPU-Z and Everest and this high an overclock. Mind you these temperatures were without the side window in the case, but that does not matter much, because normally I have a fan mounted on the side window blowing cold air towards the push Scythe Ultra Kaze fan.

    I took a picture of the Antec 1200 and from running prime95.

    I have one but my case is too small I am going to just pull it out and run on the bench 4 a while.

    poul, thats tripped out ! i've been looking for something clearly stating what those exact codes mean. And you post them without me even asking! And yes, all i see is the 101 and 124. Oh yeah, and everest actually reads the dram voltage at like 1.632, so i think bumping it to 1.66 in the bios would be safe. I also heard from a serious computer expert that having the command rate set to 1t can cause serious , serious instability and may be a major cause of my clocking problems. Ill be home soon tonite and get on it. let ya know how it goes! THANKS POUL!

    1T is perfectly fine and is suggested on X58, now in the past on DDR3 or DDR2 boards this could cause instability if things were not adjusted right and of course this is still true but not as bad as in the past. You should be using 1T, 2T should only be needed if you have generic memory really.

    As said above what BSOD error # do you see? If it is 0x00000124 you need more QPI/Vtt as you suspected.


    The thing is about QPI/Vtt voltage is that it only needs to remain within .5 of Vdimm. You can use up to 1.6 safely and I have used far more, you just always must maintain the voltages within the .5 difference to be safe.

    Here is some examples in regards to this .5 difference. For example if you want to use 1.85v Vdimm you must use at least 1.35v QPI/Vtt to maintain the .5 difference, and if you want to use 1.65 QPI/Vtt you must use Vdimm within the 1.65V-2.15V range to maintain the difference. This is why the boards default to 1.15V QPI/Vtt at 1.65V Vdimm, to maintain the ratio.

    Let's take OCZ for example, only due to their public posting of XMP setitngs and thier in house testing standards. The tests all their high end modules (High Speed/Tight Timings) at 1.6 QPI/Vtt so you know it is safe. And several other companies have QPI/Vtt XMP settings at stock of 1.6-1.7V.

    Here is an example of OCZ suggested settings for 1866 memory with QPI/Vtt XMP of 1.6V on a Gigabyte board
    Gigabyte EX58-UD4P BIOS Settings for TR3X3G1866C9F & TR3X6G1866C9DF - The Corsair Support Forums

    And here in their XMS3 Testing and Qualification pages, at the bottom of the page you will find several sets of triple channel DDR3 get suggested 1.6V QPI/Vtt to run at stock speeds
    Dominator Qualifications and Testing! - The Corsair Support Forums

    Patriot Memory also suggests up to 1.67 QPI/Vtt for some memory speeds >>>
    http://www.patriotmem.com/forums/showthread.php?t=1559

    Here is some pics of some testing I am doing for a upcoming review I am working on. You can see that sometimes even at a ram's stock 1600Mhz spec timings, depending on the ram and or other settings, you may need more than 1.35 QPI/Vtt anyway. << That comment is why I am against using XMP as a setting, and I why I think QPI/Vtt should not be a part of XMP Programming. Aside from each CPU's IMC variances and some needing more than others, XMP Settings can incorrect due to differences between many things/settings at varying Blck's. Such as at 1600Mhz ram speed using 133 Blck Vs 200 Blck, XMP settings would use the same settings for either Blck, would you? I thought not......

    Mushkin DDR3 Triple Channel XP # 998679

    1600Mhz (6-7-6-18) 1.435 QPI/Vtt 1.68 Vdimm (Higher QPI/Vtt Needed for tight timings) - Click to Enlarge




    2000Mhz (8-9-8-24) 1.635 QPI/Vtt 1.66 Vdimm (Higher QPI/Vtt Needed for high speed) - Click to Enlarge




    Of course at any Freq or timings, you can often use either Vdimm or QPI/Vtt to achieve desired results. It depends on your own personal methods and or other system settings such as SMM or Uncore which you would want to use to achieve the desired result. Some CPU's will of course need a certain range to be maintained between these two voltages, otherwise things such as channel drop outs (Only 4GB out of 6GB Showing), or failure to boot occurs. Others will allow a much wider differences or closer amounts and remain stable. It all depends on the CPU in question, and the freq of all things considered, just how any CPU is going to react to these voltages.

    Thanks for the info LSD. Good news is , last nite i was able to reach a stable OC of 3.990 (210x19) using 1.4vcore in bios (1.38 indows) and 1.38 qpi . I went nuts trying to get the 211 blck, but i keep on getting the 124 error code for more QPI volts. It kept wanting more and more , think i took it upto 1.44 and just stopped there for the night. I have seen a thread by you before showing these error codes and could not find it again, then poul posted them here courtesy of you. This was a major help to me . i have a ton of screens im going to post showing the progress, just need to make a little more. at the 3.990 my temps stay under 68 with HT off .

    My brother has the same identical setup and we tried cloning my settings to his, and it dont work. He his stuck where i originally had a problem of passing the 3.6 mark. And i do think this is having to do with his case connections to the mobo such as fans to mobo fan headers and top USB and audio connections which is our only difference and is what i did(disconnect them) to cross that 3.6 . HIS DOES NOT BOOT TO WINDOWS . he can save the settings and it shows a bios screen after , goes black and stays black.

    I will probly use 19x200 to give me 3.8 for my 24/7 settings and work on my voltages and ram now. OCZ says 7-7-7-20 at 1.6v. This only worked for me at clocks under 3.5. right now im at 8-8-8-24.
    Newegg.com - OCZ 6GB &#40;3 x 2GB&#41; 240-Pin DDR3 SDRAM DDR3 1333 &#40;PC3 10666&#41; Triple Channel Kit Desktop Memory Model OCZ3X1333LV6GK - Desktop Memory
    thats my ram, seems its been deactivated.
    Correct me if im wrong , but the looser the timings, the stabler it is overall. Like using the timings i have now as opposed to OCZs. If i were to change those timings to say, 9-9-9-24, would that help me pass 4.0 in anyway?

    Tonite i will bump the qpi up a few more notches now that u say its safe as long as its .5v from dram voltage which is 1.66 now. No problem there. LSD, i would appreciate your thoughts on my bro's system not booting properly , even though his settings are matching mine as well as memory timings and stability.

    Lastly, a couple of times i recieved an error saying something along the lines of a clock interval between second processor was not received in time , this is while loading windows . Any idea as to what this may be related to?
    Thanks- Dan.
