    Lots of folks have reported the new Elpida 50mm Hyper IC modules used for the high end triple channel memory kits fairs pretty well for overclocking on X48 DDR3 platform. So decided to check it out with my 3x2GB Kingston HyperX T1 DDR3-2000Mhz CAS8 Triple Channel kit (KHX16000D3ULT1K3/6GX) on Asus Rampage Extreme as my DFI UT X58-T3EH8 is occupied for other tests.

    System:
    • E3110 Q750A158
    • OCZ Vendetta 2 Air
    • Asus Rampage Extreme 1104 bios
    • 128MB Gainward FX5200 PCI
    • 3x 2GB Kingston HyperX T1 DDR3-2000Mhz CAS8 Triple Channel kit (KHX16000D3ULT1K3/6GX)
    • 1TB Samsung SATAII
    • Pioneer 216 DVD-RW
    • Corsair HX1000
    • WinXP Pro SP3 nLite fully updated

    Lots of folks have reported 3x2GB Kingston HyperX T1 DDR3-2000Mhz CAS8 Triple Channel kits having a module failure or a poor module within their 3x2GB kit on X58 platform. So I decided to kill 2 birds with 1 stone so to speak. I will test each 2GB module individually on Rampage Extreme's optimal dimm slots A2+B2. Each 2GB module will be tested on A2 and then B2 dimm slots using quick Memtest86+ v2.11 loop test #5 for 10 passes minimum. Not a stressful test but enough to weed out which 2GB modules are the better of the 3 modules to be paired for dual channel 2x2GB operation on Rampage Extreme.

    I used a bit of masking tape to label each 2GB module - #1, #2 and #3 modules respectively.

    Results​


    Results for 8.5x cpu multiplier and main 8-8-8-24 timings on 266FSB Strap 1:2 divider.

    At certain frequency subtimings for tRTR_S/RTR_D and tWTW_S/WTW_D had to be reduced to 5/9 for each pair for read to read same and different ranks and write to write same and different ranks respectively to pass test #5 loop. This reduced memtest reported bandwidth by ~10.5%. Still great once you factor in dual channel bandwidth will be higher.

    i.e. at 950mhz and 960mhz respectively bandwidth dropped from AUTO subtimings to manually set to above from 6145MB/s to 5500MB/s and 6210MB/s to 5558MB/s.

    With looser subtimings for at:

    • tRTR_S= 5
    • tRTR_D = 9
    • tWTW_S = 5
    • tWTW_D = 9

    • 970mhz = 5616MB/s
    • 990mhz = 5732MB/s
    • 1000mhz = 5790MB/s

    Module #3 in A2 and B2 dimm slot
    • WTF even at 666mhz 8-8-8-24 = DET DDRAM error on POSTLED code couldn't boot system in A2 dimm slot.
    • Moved to B2 dimm slot and only after clearing CMOS got CMOS ERROR POSTLED code.
    • So installed module #1 in A2 and problematic module #3 in B2 dimm slots and it booted into bios fine after clearing CMOS. SPD values read 9-9-9-24 tRFC 74 with 1.64v default vdimm set by bios.
    • So in B2 dimm slot tried 8-8-8-24 and again = DET DDRAM error no boot.
    • So in B2 dimm slot change to 9-9-9-24 timinsg and it booted up into memtest fine at 1.67v but to get into windows needed 1.7v but windows seems like it had some graphic/display corruption!
    • Down clocked memory to DDR3-1066Mhz 9-9-9-24 and windows didn't have corruption enough to get a screenshot of cpuz spd for both module #1 and #3 together as i wanted to grab the SPDTool profile for them but system rebooted due to module #3 instability before I could open up SPDTool :(
    • Looks like module #3 is really a dud :(

    Module #3 cut short my tests for B2 dimm slot testing, so will do that later with module #1 and #2 in B2 and update this post with the results later on.

    Conclusion:
    As you can see module #1 didn't fair that well compared to module #2. At 950mhz it already required the 4 mentioned subtimings to be loosened at least 10mhz earlier/lower than when module #2 needed to touch those subtimings. Module #2 continued to scale all the way to 990Mhz at same vdimm voltage until 1000Mhz which needed vdimm bump from 1.72306v to 1.74956v. I didn't apply much more vdimm over that for 2GB single module testing so as to leave room for when dual channel is tested which will require more vdimm usually. Module #3 on the other hand was a complete dud which I'd deem faulty by any definition :(

    As you can see there are differences amongst the 3x 2GB modules even on X48. Will these differences translate over on X58 in triple channel mode ? Are these differences one explanation as to reason some folks reporting these 3x2GB Kingston HyperX T1 2000 CAS8 kits have one module failing or not hitting rated speeds ??

    Module #3 was a disappointment and could be reason why on DFI UT X58-T3EH8 i got 4GB detected out of 6GB in a few different module/dimm slot combinations. If the modules were placed in a certain dimm slot configuration, all 6GB was detected at DDR3-2000Mhz 8-8-8-24 on DFI UT X58-T3EH8. Same with certain CPU VTT and VDIMM combinations 6GB was detected instead of 2GB or 4GB (memory tip #6). But didn't test this kit much as Corsair Dominator GT kit was busy on DFI UT X58-T3EH8.

    I'd say worth looking into testing each module individually if you are having 3x2GB issues on X58 platform as well. Of course module #3 would be deemed faulty for not running rated timings at least 8-8-8-24 for lowly DDR3-1066mhz to DDR3-1333Mhz underclock!.

    What is it wid Kingston Hyper X ram.

    I like the brand Kingston and they have been around for ages.
    But this looks like another Hyper x failer.

    My last DDR2 HX both new and old had failed tests in Prime and Orthos.:confused:

    I add..
    You really got thing happening on your X58 LP mobo :)

    Yeah it's a shame to see this - it's been ages since I used any Kingston memory - last was KHX/2700/3200 Winbond BH-5/6 on DDR1 hehe

    After many hours of testing my kit following your advise eva i have 2 faulty dimms.
    I've already called kingston support to make sure and they told me to return it, but said it was rare that i would end up with 2 dimms that are faulty.

    So these three sticks managed to go 950mhz, 1000mhz and 533 mhz? How fast is DDR3-2000 supposed to go?

    lots of reports for 3x2GB Kingston 2000cas8 T1 HyperX kits with modules failing on X58 boards, not many would hold same ratings on X48 chipset boards as different platforms so wasn't expecting these modules to do rated timings at rated vdimm - but at least close similar to module #2.

    BUT, for X58 triple channel remember if you test individual modules the X58 chipset has requirements for 1 or 2 modules to be placed in certain dimm slots - usually 1 or 2 modules need to be in dimm 2+4 slots and can't be in dimm 1+3+5 or on some boards not even 6 - they must be in dimm 2 or 4 slots or you won't get system to boot. X48 board above does not have such a requirement.

    not sure how far on X48 chipset as first time using elpida 50mm hyper based modules on this chipset. They should hit rated speed/timings on rated X58 chipset boards for i7/x58. But clearly one module is out of spec regardless of platform as you can see above.

    with remaining 2x2GB Kingston HyperX T1 2000CAS8 Elpida 50mm Hyper modules pretty hard to find stable points even for just HyperPi dual 32M run. So far with skew and other voltage tweaks set, managed to pull off DDR3-1820Mhz 8-8-8-24 AUTO CMD rate is apparently 2T at 1.723v vdimm.

    What I mean is, I would expect sticks rated at DDR3-2000 to get 2000mhz (or 1000mhz if they double the numbers). Even the one you got to 950mhz I would consider defective.

    I'm setting up an X58 system soon and looking at which ram to buy, and the DDR3-2000 kits are quite a bit more expensive than the DDR3-1600 kits. If you can only get a 2000 kit to run 1820, ... that's bad, isn't it?

    I'm a bit of a noob here, just been out of the loop for a while. My desktop at home is DDR1-400

    You have to factor in differences in chipsets X48 vs X58 as X48 has NB memory controller and X58 has IMC integrated mem controller on i7 cpus. These modules are rated for i7 x58 triple channel so might not translate directly to older chipsets such as X48. I wasn't expecting same clocks with same memory voltage on X48 as X58 but it would be close in terms of frequency. I knew memory voltage will be different as X58/i7 mem controller is better than X48.

    It would be bad if DDR3-1820 was on X58/i7 but as to X48 you have to factor in chipset and the board. Rampage Extreme particular you have to get the clock skews and voltages right other wise some memory probably won't even run DDR3-1333/1600 out of the box if you manually set the wrong skews/fsb strap straps on Rampage Extreme X48 board etc

    Same memory made for X58 might behave differenly on X48 or even AMD AM3+ platforms

    I did the testing on slots 2,4,6. Module #1 boots up fine on all 3 slots, while the other 2 modules failed to boot in any slot.

    Clearly, you can see that the replacement kit is much better and working very nicely for Vdimm required as well.

    Module #3 seems to be the tricky one again falling short of 1000Mhz 8-8-8-24 and requiring a bit more in terms of Skew tweaking needing CTL Skew Delay 100ps from 970-990mhz. Although in terms #3 module handled tighter sub timings for tRTR_S/RTR_D and tWTW_S/WTW_D than module #1 where up to 960mhz it was like module #2.

    Granted this kit wasn't validated on X48 chipset and is meant for triple channel, so guess we shall see how the entire kit performs on Core i7/X58 platform later on :)

    Update: For dual channel it seems module #1 is best in A2 Dimm slot and #2 would be best candidate for B2 Dimm slot, so tested module #2 in B2 Dimm slot and surprised by the result of how it handled tighter tRTR_S/RTR_D and tWTW_S/WTW_D timings (default 4/7 and 4/7 respectively) all the way up to 980Mhz 8-8-8-24!

    Nice results eva :thumbup:

    I have had unsuccessful results with 2 sets of Corsair Dominator GT so I ordered some of this stuff last Monday, it should be here tomorrow :)

    thanks updated previous post with module #2 and B2 dimm slot results.

    Sorry to hear about your GTs, i think it's elpida issue so some batches regardless of brand might be prone to issues. Hoping my rma replacements aren't one of the batches heh.

    Sweet

    It looks as if it will take a bit of fiddling to get them to work at 2000mhz (or close) but i'd imagine that it would be easier on X58 boards rather than X48.

    Yeah it may be an issue with the chips or possibly that the memory controller on my 920 D0 is weak.

    I hope it isn't.

    Yeah does take some more fiddling on X48 probably cause chipset doesn't handle 2x2GB as well as i7/X58 for 2GB density modules

    Dual Channel​


    Testing module #1 (A2 dimm slot) + #2 (B2 dimm slot) for dual channel on Asus Rampage Extreme and looking very good so far without needing to sacrifice any subtiming tight timings for tRTR_S/RTR_D and tWTW_S/WTW_D.

    266FSB Strap
    FSB = 1.27241v
    NB = 1.60372v
    VDIMM = 1.65681v
    NB Vref = -17.5mv
    A2 Clk Skew = Advance 250ps
    B2 Clk Skew = Delay 100ps

    Seems like a lot of people are having problems with Elpida based chips.

    There is a massive thread over at xtremesystems.

    Yeah could be batch batches of elpida hyper ics who knows... fingers crossed this set isn't one of them :)


    Looking pretty good for 2x2GB Kingston 2000C8 dual channel @DDR3-1900Mhz 8-8-8-24 1T for single Super Pi 32M at least. As expected needed slightly more NB and vdimm voltage compared to same memory frequencies for single 2GB module testing.

    2T vs 1T - memtest86+ v2.11 reported bandwidth difference was 6953Mhz vs 7210Mhz.

    Didn't have to touch tRTR_S/RTR_D and tWTW_S/WTW_D timings at all from auto :)

    @DDR3-2042Mhz 8-8-8-24 1T


    At same vdimm 1.67006v bios validation @DDR3-2042Mhz 8-8-8-24 1T
