3x2GB Kingston HyperX T1 2000CAS8 - Elpida 50mm Hyper X48 DDR3

**eva2000** · 06-08-2009, 06:07 AM

Purchased this kit off these forums back in February 2009 but haven't tested it much as GT kit was keeping me occupied

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!.

wow Kit Mem does not reach same speed

**ci2kla** · 06-09-2009, 10:20 PM

Oh sorry to hear that eva, thx for the test btw and...did you tested that 2 fine modules in dual channel? if yes what did you get from them?

**eva2000** · 06-10-2009, 02:34 AM

Yeah same was hoping for some nice dual and triple channel action. Testing 2x2GB on REX right now working on getting 940-950mhz 8-8-8-24 stable - guess module #1 holding back #2 in dual channel heh.

**runmc** · 06-10-2009, 02:54 AM

Since they were second hand

Kingston will RMA them in a heartbeat.

**George_o/c** · 06-10-2009, 07:08 AM

George in case you can RMA them like Ron says here, it would be cool to see results from all of them on A2 and B2 slots respectively, so far great

**eva2000** · 06-10-2009, 08:00 AM

Never dealt with Kingston RMA - web site site says only original purchaser has warranty rights ?? What's folks' experiences like for rma with Kingston if you aren't original owner ?

Anyway 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.

not sure how other elpida 50mm hyper compare on Rampage Extreme/X48 DDR3 boards in terms of mhz to vdimm scaling ?

**filmbot** · 06-10-2009, 07:46 PM

I'm ordering a kit tonight and will test on my REX as soon as they arrive. Hopefully will have results by mid to end of next week.

As always, thanks for the very informative memory settings

**eva2000** · 06-13-2009, 04:32 AM

Hope you get better results than me

**filmbot** · 06-15-2009, 07:31 PM

Initial results are buggy at best. First I was having problems passing Hyper Pi 1M. It would run and finish all loops but then not give calc done box, same with 32M. Then I tried copying Dsjjangs settings as best as I could (http://ocxtreme.org/forumenus/showpo...48&postcount=1). Eventually I got 1M to give the calc done box but no luck with 32M

It just sits there then I start getting artifacts everywhere as you can see here

I have a few ideas of whats the problem but going to search around some more and see what I can find. Any updates Eva?

**eva2000** · 06-16-2009, 02:58 AM

Well try my bios settings at http://i4memory.com/f83/3x2gb-kingst...3-tests-18365/

for dual channel on Rampage extreme i had to loosen subtimings alot from default 4-7-4-7 to something like 9-11-9-11

READ to READ delay(S) : 9
READ to READ delay(D) : 11
WRITE to WRITE delay(S) : 9
WRITE to WRITE delay(D) : 11

my RMA has been approved by Kingston just need to contact local distributor to arrange replacement kit so will see how the replacements will fair

Nice eva2000 I am looking forward to your review of the DFI JR X58-T3H6 - MicroATX with this memory. I have 2 kits of it sitting here.. Still wondering if I should go Asus Gene or DFI JR.. I wait for your review..

Will try that tonight when I get home. Seems 3oh6 is interested in this same setup and may be coming through here in a few days to discuss. If so, you guys are some of the best memory tweakers out there and should figure this out

EDIT: Forgot to say I'm on 1201, going to switch back to 1104 so I can get DIMM skew adjustments, see if that helps at all.

Yup next up is DFI JR X58 testing - lots to read and learn first hehe

haven't tried 1201 only 1104 myself.. but the skew and nb ddr vref adjustments I mentioned was key to even getting DDR3-1600Mhz 8-8-8-24 stable in memtest! One right settings were made - pushing to DDR3-1820-1900Mhz 8-8-8-24 in memtest was fine although 2x32m pi managed only DDR3-1820mhz.

**eva2000** · 06-26-2009, 01:13 AM

My RMA replacements arrived today - minus the original box packaging hehe

Fingers crossed

Bit of info from Kingston regarding the labels on modules - interesting to see the results of Kingston 2000C8 in relation to their serial numbers

**KILLER_K** · 06-26-2009, 08:31 AM

Hope this kit works 100%, let us know what happens.

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

Same Memtest86+ v2.11 test #5 10x loops with reported bandwidth and settings used. For initial tests trying to keep VDIMM as close to 1.65v rated volts first - the aim is to see how high I can clock the memory without errors at such VDIMM voltage.

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

Very well organised testing report!

Seems the X48 has reached it's limits.
Are you testing those kits in dual channel?

**eva2000** · 06-27-2009, 10:35 PM

Dual channel is next then X58/triple channel

**Leeghoofd** · 06-28-2009, 12:52 AM

Excellent testing as always George, you're the REAL RAM GUY !!

On monday I should get a Kingston 2000C8 set, will test them on my Gene II ( at the moment at 2200mhz with the Blades at 8-9-8-24 )

**eva2000** · 06-28-2009, 01:19 AM

Thanks wish you all the best with your kit

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!

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.

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.

2T

1T

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

Currently burning them in C7-7-7-24 1.6Vdimm at 1800mhz
