    i7 860 / P55 GD 80 / 4 sticks RAM

    I have been told I might need more juice to stabilize four sticks.

    I did an uber job of cleaning up inside of the case airflow couldnt get much better. I got pics too. I could try a push instead of a pull, and reseating the
    HSF, as when I was ghetto-ing the fan on, it twisted around alot. The base if the HSF is so smooth, its a friggin chrome mirror, but even with the mounting clip, it still "swivels", but, so did the Ultima 90, so meh.

    I am having a great deal of difficulty getting OC nailed down again.

    The Venomous X is doing a great job with the high cfm fan on it, about 5-7 C better than the Ultima 90, under full load with IntelBurnTest.

    I want to keep 1T, which is supposed to be possible now with 4 sticks (but more juice, etc.)

    Anyone running 4 sticks Ram, i7 860, and this MB post your settings ? All I can find online is either "heres me at 3.5" or "this is me at 4.3 on water".

    i7 860, P55 GD80, Bios 1.6 (1.7 is on msi site, but is even less stable),
    Specs in sig, havent even gotten to start playing with new GTX 470 yet.
    I am close to giving up and staying at 3.6Ghz, which will irritate the hell out of me, since I bought the new HSF so I could get better temps, and I DO, but having alot of trouble getting MOARCLOCKS!

    Did I shoot myself in the foot real bad with 4 x 2GB ?

    I have gotten to what I thought was very close, with IBT, then when I try the Very High stress level, I get an error on run 2 or 5.

    I have tried relaxing RAM, does not seem much of an issue, it is specd 6-8-6-24, and was very happy 1T with 2 sticks and even tighter timings. For the time being I am using 8-8-8 just to be safe.

    My goal is : 4 sticks of RAM @ 1T, HT on, and as fast as I can go and stay under 70c while max stress IntelBurnTest.

    Reasoning : I paid for the HT and when gaming I am about 6c or more under the IBT temps, so that gives me room to breathe with the hot GTX470..

    Last successfull test was @
    but 71-72 C, so no dice for me. Maybe I have to settle for 3.7 on air, with my other requirements ? (HT, 4 sticks @1t)

    181x21 3.8Ghz
    1.262 Vcore (1.288 under load, I LIKE "low vdroop
    1.19 VTT
    1.81 PLL
    1.635 DRAM Volts (spec is 1.6, this gives it 1.605 according to msi utility, only using to monitor)
    PCH Auto (1.05) - I have read that upping PCH will let me lower Vcore, is that true ?

    Re: i7 860 / P55 GD 80 / 4 sticks RAM

    Why be stuck on 1T at least for now? With the large caches and faster processing speeds you should get better performance.
    You will loose some points on bandwidth tests but that doesn't effect execution. At least that is my experience with AMD's since the K8. Since intel went with the on processor memory controller they no longer have the memory/FSB bottleneck that plagued them earlier (even the C2D's were much better off due to the large caches)

    Re: i7 860 / P55 GD 80 / 4 sticks RAM

    Good question. Only because I am under the impression, that while overall RAM timings have say... not as much to do with responsiveness, or gaming, as clock cycles and the class of your gpu... that out of all the timings, Command Rate 1 or Command Rate 2, makes the biggest difference. After that its CAS timing, and after that one, I am fairly well lost. However I DID get things stable finally with all for sticks at 1T-6-8-6-24-88-10-6-6-6-Auto(30) with a 4 divider. On 2 sticks I was able to time it 6-6-6-20-74-10-4-5-4-Auto (I cant set it again to check the last one). The comp felt much mroe responsive, at the faster timings, I admit I didnt bench both, so It could have been "placebo".

    Good enough for now, I have to say I am pleased with what is actually the "XMP" Profile in the sticks for 1600MHZ, they are at 1400-ish depending on Bclock. And with2 sticks board wants to time them at 2T, but I set it back 1, and 6-8-6-24, and it is happy. With 4 sticks, there is no tweaking of timings, not on this board. 1.206 is as far as I am willing to go on the VTT, and it took that to make it Maximum Stress stable on IBT. Next setting down is 1.9 and it would pass all but Max stress. I am pulling later to reseat HSF but for now it is folding stable 3.8Ghz @ 63/62/62/65 c. and its 78F in my room. Damn AC shot off when I was sleepin. Found out I CANT fold on the GTX 470, so later on I will toss the 8800GTS back in and drop a gpu client on it.

    So are you saying, that I'd be faster with slower timings ? Faster to me means low latency and responsiveness. I am the type that notices a speed difference between Raid0 and just 1 drive, in everything I do. Bandwidth never meant squat, since I never max it out. Cmon, after all wasnt ddr400, 3.2 Gb/s ? Idk and we are up to ddr3 and triple channel, I just want zoom zoom.

    Re: i7 860 / P55 GD 80 / 4 sticks RAM Success

    edit by myself. these are not as stable as I thought, please accept my apologies. I think we all have a responsibility before we post "this works"

    Stable settings for 3.8, 3.7 and 3.6 Ghz.
    All speeds EIST, Turbo, Crap that saves your CPU if you push it too hard, etc, turned off
    HT is ON. Ram Timings 2T 8-8-8-24-88-10-6-6-6-30 ratio 4, QPI 16, LowVDroop on (LLC for some of you) PLL 1.81 DRAM 1.635 PCH 1.094
    Ram is not getting juiced, board undervolts it a touch, so 1.635 shows me 1.605. Temps given for full load IBT maximum stress, and highest core temps reported by Real Temp 3.40 during the run. Room temp 75F-77F, closed case.

    ****3.8 Ghz****
    Vcore 1.237 (1.272 load)
    VTT 1.206
    69-71c
    ****3.7 Ghz****
    Vcore 1.2 (1.232)
    VTT 1.174
    64-66c
    ****3.6 Ghz****
    Vcore 1.168 (1.192)
    VTT 1.158
    60-61c

    Hope this helps you if you have similar rig.

    So are you saying, that I'd be faster with slower timings ?
    If you have a faster processor clock, yes.

    Even with out an increase and without caches (which memory latency doesn't effect) the difference is only a few millionths of a second, on the first address only as the following addresses are read the next clock till a different memory location. Add in the caches and it hardly ever matters at all.

    Re: i7 860 / P55 GD 80 / 4 sticks RAM

    Thanks. I just didnt know any better, now I do. For anyone else following, I did some benches, and the difference in 3dmark05 for instance, was less than half a percent. @ glas - Yeah, it makes sense now. I had always tended to hit a wall from overall clock speed and temps, so at that point, since I couldnt go any faster I would tighten up ram timings. Will save me alot of time in the future.

    Re: i7 860 / P55 GD 80 / 4 sticks RAM

    Well, I ended up at specs in my sig. There is more room left, and the MX-3, even though it says no break in, is doing a bit better now, my hottest core folding is 55c. It was not an issue of temps, but stability. I tried reading every guide I could find, and I simply couldnt figure out what to crank up and how much. After 3.65 Ghz or so it got really tricky.

    An OC story that is pretty common I guess..... I would think I was stable, and do another stress test run at the next or max level, and then it would fail THAT one. Sure 3.6 is plenty, just feels lame to "give up". But I wanted to start enjoying the gear I just paid for.

    3.6 Ghz, with HT on, full load Linpack 61c, is not too bad ?

    I'll put up my BIOS settings after I get back from class, maybe you have some ideas ?
