    disabling HT will increase GFlops in IBT/Linx. Not sure as to the technical explanation why but it's always been the case.

    Guys its been ages since I touched a 1366 cpu and I have lost my way with overclocking one. I did some benchies at stock then set BCLK to 200 but what should QPI data link rate be set to? At the moment its 7218 which is the lowest before slow mode. I have my ram set to 2000 and UCLK to 4000, vcore to 1.35, vdimm to 1.65, qpi/dram core voltage to 1.35, cpu pll to 1.9475 (turns red above that), thes eare set off my old noted and advice I got from snappy, but set like that it wont post, so what have I messed up? Any help would be great.

    Im going to drop my ram speed in case this mobo doesnt like my Kingston 2000 rams .

    Yeah I did try 1.4v also and it didnt help. I think I am on right track now, just benched it at 4200 and going for 4400 now. I disabled some cpu features but also saw that bios seems to be forcing too tight timings on my ram for some reason, but now its running they are correct, so i dont really know but its runnning. Multi was on auto coz i like speedstep etc to work but its now 21x.

    Better to set multi manually all those power saving settings just add to instability. Good luck with 4.4 my 950 needs mega volts to get stable anything past 4.2

    yeah 4.4 is a bitch! i need atleast 1.45v and it still flaky

    i find even multi (ie 20 x 200 or 22 x 191) just plain suck and always BSOD.

    so i always use odd multi's

    That should be easy, just pump your multi up as far as it will go then same for bclk until it bsods then drop it back a couple of clicks (afaik), I dont think it will reach 4.2 though unless you force the extra turbo multi, Im not sure as I havent tried one yet.

    Guys, other than vcore - which voltages will help BCLK overclocking? I just cant get this thing stable at 210 even with reduced multi.

    I have an i7-920 / Asus P6T Deluxe V.2 / 6Gb G.Skill Trident F3-16000CL9T-6GBTD and stock intel cooler....I have tried overclocking just a little bit but when I do this my games lock up almost straight away and I get loud clicking through my headphones....is there anyone that can guide me step by step the safest way to do this?

    Just want to see if its worth getting a better cooler or just upgrade the whole thing to 2600K

    So I just built a new system last week with an i7 2600K, Asus P8P67 pro and a Coolermaster Hyper 212+ cooler. After reading up on a few overclocking guides about i7's I had a go at it today and am currently running Prime95 @ 4.4Ghz with 1.270 vcore, temps are around the 74deg mark. Is that too hot? The fan on my cpu cooler is a silent type and only runs @ 800 rpm, so I will be getting a faster fan this week.

    nah 74 while priming is fine, it will be 10 degress cooler while gaming.

    Ah OK cheers, the fan i'm running is only about 10dBa so if I can keep that at the speed i'm getting i'll be very happy :thumbup:

    EDIT: After an hour of Crysis my max temp was 50 degrees in RealTemp :)

    I've currently got mine at 3.8GHz with HT. I'm wondering about disabling HT and cranking up the speed to see if it might improve gaming performance.

    I'm specifically talking about The Witcher 2. Any suggestions? Good idea/bad idea?

    Cheers, fellas.

    PCIE Frequency to 103-105, CPU PLL to 1.55v (if it posts), QPI/VTT to 1.45v. That might work.

    ok guys my new rig which atm is apart due to me getting some blocks nickel plated ha currently got to these speeds (ill post pics and screen shots once its reassembled

    Intel Core i7 950 + Swiftech Apogee GTZ @ 4250mhz HT on
    gigabyte x58a ud3, 6gb gskill 1600mhz (1480mhz)
    evga 470 gtx + Swiftech mcw 80 @ 900mhz core
    ocz vertex 2 60gb + Windows 7 64 bit

    i've been playing around with the ram trying to get it's speed up but the boost in voltage was taking the NB too high so im putting it on water aswell to really get the max overclock out of it

    as it stands at that clock i generally pull 9.500 on the super pi 1M
    i have been able to get this chip stable at 215 blck however my dirty block was holding me back with my temps, hopefully by this weekend i will have it back and i can do some more benchmarking

    i'll post some screen shots when done

    so i decided to run prime95 to see temps.. and in room thats 22 or so so degrees after just 5 mins on prime95 I was seeing some high temps!

    should I aim for lower? maybe the ole h50 with noccies needs upgrading!!

    rig in sig

    EDIT: got XSPC 360 W/C kit and max is 63 degrees now :D


    Is there a post your overclock settings thread???
