    Mushkin 997015 2133 1.5v 2x4Mb
    Intel DZ68DC
    I can NOT get this ram to boot at 2133 XMP or manual settings.
    Supposed to be 1.5v chips but even trying 1.65 they refuse to go
    I can run 186x stble but it's a big waste if they wont run at spec and I dont know any more tricks! tried looser timings, stepped volts up thru 1.65 did a hundred combo's trying i'm stumped?
    Sadly I cant use the new found Samsung sticks as there is already a known issue with "Low Profile" sticks on Intel Z68 Extreme's:mad:

    This may be a board limitation rather than the sticks. Some board just won't do 2133. However, I have a couple of questions. First, how loose did you go with with primary timings? Did you try CAS 10, just to see? Also, you may want to look at secondary timings. If they are PSC sticks (as I suspect), the key may be there.Also, have you tried bumping up VTT? Many high speed sticks require this.
     
    revin and cadaveca say thanks.

    I tried step's to 12's and 29 and stepping voltage up to 1.65
    There rated 2133 10 11 10 28 at 1.5 volts, and my experiance with Mushkin has been "better" than advertised settings, and these are supposed to be the "creme of the crop" set.

    At 1 point when I was just setting up BIOS, I had got 2102 manully but after I did reboot to change other CPU stuff I lost it in the maze of sooo many try's

    I'm not sure where my VTT is because of the Intel BIOS wording for rocket scientest lol
    Here is shot of the sub timings tht I dont know jack, so mabey you can spot something to change

    Thank you greatly !!

    Does it allow you to tweak beyond the primary 4? I do think it's important for you to find out what VTT is for your board. It could make all of the difference. I suggest you google it. ;)

    Your board doesn't officially support 2133mhz RAM, it say's 1600+ nothing about 2133mhz

    You can try 1000 mhz 9-10-9-28 or 9-10-10-28
    it will not be much slower

    Honestly, on Sandy Bridge systems, anything beyond 1866 has significant diminishing returns. However, from the perspective of the OP, he wants to get what he paid for.

    This I absolutely agree.

    By the way, the 2x4 gb modules sometimes require command rate=2T.
    revin, have you tried to set 2T?

    Yes I can change all sub-set timings

    If you ment 500/1000 I'm able to already do 1866 9.9.9.26.1t
    I'm Bclk locked so 1066 is lowest I can select then 1333, 1866, or 2133, but when I tried uping Bclk and thus uped ram multi, it is no go even set at 12's



    Yes did 2t's

    The Intel P67 was certified for 2133, and it would tend to think that the Z68 "should" also but,....... I may be SOL

    Thank you again
    I think that VTT is "System Agent", I'll keep studying..........
    I think my MaxxMEM looks like they have good results
    Might be best to go back to my first thoughts of 4x4 1600 and call it good!
    But then again, 2133's at 1.5v was hard to pass up :wtf:

    I'm all over it
    It is hard to decipher over to intel's "crap but i'm learnig!! [i think?!!]

    That run looks pretty good. Can't see you scoring much better than that with 2133 and tighter timings. I'd stability test those speeds and timings, and if they are stable, I'd be quite happy.

    Excellent memory bandwidth. Still try to set command rate 2T . My corsair 2x4 does not start more than 1900, if CR not 2T. When I had 2x2 modules, they worked fine in 2000 1T, larger memory need 2T.

    I had almost identical issues albeit on a different platform, I tried damn near everything over a period of weeks, in the end I set everything to auto in relation to the memory and they booted first time. then much to my dismay, I found Iwas getting better benches at 1600mhz at 6-6-6-18 than I was at 2000mhz @ 9-9-9-26, but as I said, that was on a S1366.

    Even better now up to 103 Blck
    Some reason I got a report in older XTU that mem temp "over" at 128c
    yet I'm only using 1.55v

    NOTE
    I may have hit that magicial "24Gb/s" wall
    Can you spot the issue?
    :toast:

    Thank you Pauli, Taty, and Dave :rockout::respect:
    I'll keep trying with these, I'm not sure it's worth a "gamble" to try the Samsung sticks since Intel has "Reporting" a known issue with "small/short" sticks, BUT I really wanted to do 16Gb
    for the video Editing, and a ramdisk, but...........IDK,

    I seen when going thru the MaxxMem spread sheet, these do indeed seem to be pretty strong, albeit it's just another benchie, it's a base to compare to

    I have tried moving all the primary rates up and 2T also, but it just wont boot with 2133 divider enabled. 1866 stock volts boots Auto timings as seen in the screenies, so thats gotta be kinda good eh?

    Thats another item I noticed in MaxxMem, that range of scores appear to be less than where Im at with 999 1T, but still I did get a CPU boost to 4.75 :toast:
    Dave has mentioned to me the this Mem Controller is the best to date for effieancy

    Ive had the same issue with the same sticks on a 990fx crosshair V ,sys <ive not got mine past 1889 yet but its early days,im going to put some water jackets on them maybe see what theyll do, whats the highest you would go with volts on these with good cooling on them ?:confused:1.5 dosnt sound a lot :roll:

    OK Pauli, I stumbled on to something
    I see here where Dave shows a Dimm Vtt listed
    I have that option listed in my BIOS twice also, named System Agent
    It's in Voltage Overides AND under my Memeory Settings under my Dimm Voltage
    Can this be helpful with the "Sub Timings" you asked to see?

    I have tried it from 0.750 up to 1.250 with 2133

    I've never had to run 1.25v+ VTT for 2133 on just 2 sticks. So, I'm thinking it's probably not that. I think if you want to confirm it though, you could try up to 1.35v, but that's not something I feel comfortable with for 24/7 clocks. Some may disagree. I still think it's more about secondary timing. If you could post a bios shot of your secondary timings, Dave, myself and some others may be able to help more. If secondary timing adjustments don't help, I have to think it's just your board. I've never had a set of Mushkins not run rated speeds.

    Try 1866 9-10-9-24 1T 1.53v and 1.2 VTT. I think that will stabilize the ram. At 1866, I don't think you should be having issues with secondary timings. But before that, let's make sure your cpu is stable. I really like to isolate problems and rule things out 1 by 1. So, back that ram up to 1600 with fairly loose timings, then try running 20 cycles of Intel Burn In on at least high. If you pass that, we can take the cpu out of the equation. If that passes, then go with the settings I listed above and then test for a couple of hours with memtest.

    Over 1.2v VTT/VCCIO can be dangerous.

    Also, mmore VTT/VCCIO than is needed can cause stability issues, too.

    I was going to mention that your write performance on the 1866 MHz divider is very high, and that may be the cause of 2133 MHz divider not working. I have found that the board that do boot 2x4 GB or even 4x4GB, generally have a lower write bandwidth. I'm not 100% sure why 4GB DIMMs cause this increase in write bandwidth, but I do know that if you check bandwdith of those running 2133 MHz on 2x2GB DIMMs, the bandwidth is generally a fair bit lower than 4GB DIMMs.


    XTU can be a damn useful tool, BTW...nice to see you are using it...but older versions may not be giving true readings, so do be careful.
