Kingston HyperX KHX2000C9AD3T1FK3/6GX - Elpida BDBG

A few days ago I received a DDR3 Triple Channel memory kit from Kingston to overclock & review.
I started taking the photos for the review today and upon removing the heatspreaders to check which chips they carry I saw a chip I never heard of before ( the revision, not the maker / series ).
They're Elpida J1108BDBG.
There's nothing about them on Elpida's website, and google has nothing to say at all ( LOL ).

Anybody happen to have a kit with those chips or am I the only one around ? :D

Gonna run some tests later on tonight to see what they can do.

interesting indeed, thanks for sharing

will be interesting to see how they perform

they actually were on elpida website a couple of months ago (when they were produced, i suppose)
i already seen these on a couple of kingston 1333 value sets - they were nothing spectacular

I was wondering what the difference was between KHX2000C9D3T1FK3/6GX and KHX2000C9AD3T1FK3/6GX. I guess this explains it. The former which was based on BBSE seems to be discontinued along with it's CAS8 Hyper-based sibling.

I have tested some BDSE which were purely crap: 2000MHz 9-9-9-27 1.65v is no go :)

Just finished a few quick memtests.
DDR3-2000 7-9-7-24 ( tRFC 70 ) is stable at 1.68V or so.
More tests and some scores coming later on.

could BDBG be the true name for rebranded powerchips we saw recently?

I have the same kit, very nice :up:

Vmem=1,69V real

But this chip doesn't like tRCD 8

So they can't do nice tRCDs?

I'm doing some initial testing on P55 ( sigh ) as I gave my classified to tsan for some tests with his 980X, so these numbers are definitely not final, and probably not maxed out ( need to get the classified back :p: )

tCL ( CAS Latency ) 6 max stable around DDR3-1550
tCL ( CAS Latency ) 7 max stable around DDR3-2100 ( mobo/platform limit for sure )
tRCD ( RAS to CAS Delay ) 6 max stable around DDR3-1400
tRCD ( RAS to CAS Delay ) 7 max stable around DDR3-1600
tRCD ( RAS to CAS Delay ) 8 max stable around DDR3-1900
tRCD ( RAS to CAS Delay ) 9 max stable around DDR3-2100 ( mobo/platform limit for sure )
tRP ( RAS Precharge ) 5 max stable around DDR3-1600
tRP ( RAS Precharge ) 6 max stable around DDR3-1900
tRP ( RAS Precharge ) 7 max stable around DDR3-2100 ( mobo/platform limit for sure )

More to come soon

32m 1600MHz C6 done :)

Vmem 1.68V

I just saw the price for them, they're good value for money :)

in europe these cost same as hyper-based 2000c8 kit, so not so good value at the moment

This kit is available for sale this weekend (probably until Tuesday) at US electronics chain Frys for $179.99.

that's cheap US$180 = AUD$196 here, right now this kit is around AUD$299-310 versus the 6GB Kingston 2000C8 Hypers = AUD$320-375

So you're saying I should grab a kit? :D

Go for it! shame prices in OZ seem to remain high even for budget 6GB 1600mhz kits ~US$200 right now.

In South Africa the price difference is about in line with eva2000's prices, only higher on both accounts :(

I am having problems with this what I believe is the same memory except a 4GB kit

KHX2000C9AD3T1K2/4GX

What I ended up doing was buying three of those 4GB kits and I am using 6GB in my X58, 4GB on my P45 and I have a spare stick left over for testing.

I got the the above listed 4GB kit from Fry's for $129.99, it was like $142 OTD for each kit. However I can not get it to run at even 1600 c7 on my EP45T USB3P, much less 2000 c9.

I'm not surprised you can't get it to run that high on the P45 board, those kits were designed for X58 and P55 setups. And as I recall, P45+DDR3 was a really bad combination...

I too have a 4GB KHX2000C9AD3T1K2 kit ;) I could easily run 1600MHz @ 6-7-6-18 @ 1.68V MemTest stable :)

See more here: http://www.xtremesystems.org/forums/...d.php?t=250507 :up:

Apparently those chips are smaller than BASE: http://blog.ark-pc.jp/?eid=104312
However it looks like the SanMax memory that used BDGB has now switched to BABG so I don't know if BDGB is EOL too or what. Elpida makes too many ICs :wth:

you have a different kit:

KHX2000C9D3T1K2/4GX - your kit


KHX2000C9AD3T1K2/4GX - my kit

mine are rated at 9-11-9-24 @ 1.65v

DDR3-2100 9-10-9-27 2T 1.70v BIOS (=1.749v real) 21x175BCLK Single HyperPi 32M


I wanted to see how high this kit would run at its specified timings of 9-10-9, but after several failed attempts to run DDR3-2100 on 210BLCK at the 2:10 divider I decided to use 175BLCK 2:12 instead. Setting VDIMM in the BIOS to 1.70v (which gives about 1.75v real due to overvoltage) I was able to get single HyperPi 32M stable. I attempted 8x 32M but that resulted in an instant BSOD. I'm already running VTT pretty high so I'm not sure if I need more vcore, VDIMM or if the system just ain't having it.

George, if you tighten tRCD to 6 what speed can you hit Prime stable?

George's ( George O/C's I assume :p: ) more than likely have different chips.
He's a coward and AFAIK he didn't remove the heatspreader yet to check the chips.

It doesn't matter, both kits have a low price in South Africa and might just make a nice 24/7 kit ;)

Hey Oj. Didn't test with such low tRCD, ain't worth it from my point of view. 1600MHz 6-7-6-18 and 1800MHz 6-8-6-18 FULLY MemTest stable @ 1.68V ain't too shabby though :yepp: :up:

For me it's 6-6-6-x :D If you could test, say, DDR1500 6-6-6 it'd be greatly appreciated ;)

Ok I'll try for some MemTest action @ 6-6-6 @ 1.68V ;)

DDR3-2300 on air @ 1.7V done on the Classified E760 and an i7 980X Q4EG.
Screenshots, and more tests coming later on.

And triple channel DDR3-2400 on air done :D
Gotta go now, but I'll be back later on with benchmarks at 2400 or higher ;)

What timings did you need for that?

Was actually trying to test the 980X's memory controller, so I started with really really loose timings :D ( 11-11-11-31 ), but gave them a quick test at 9-11-9-30 and it passed a few #5 loops ( 2 or 3 ) before I shut it down and left the room :p:

these are on sale for 169$ in frys. are they worth buying?

For 169$ I'd say yes, it's a bargain.
Not the best solution if you are a benchmarker, but for a normal user/gamer it's more than adequate.
