Well, i've just bought an OCZ Reaper 1866 8-8-8-24.
With all of this i don't know if i should worry... How can i see the chips?
Printable View
1866 cl8 have micron I have them also the ones in the picture are cl9
People, I have a question over here. The Flexx series have Elpida Hyper? Because it dont seem that they have but, if Blade series and Reaper series have, now Im in doubt of that.
3 x 2GB Corsair 2000C7 GTs..
Installed
Booted into windows
Pressed windows reboot button
rig didn't ever boot up again
ONE stick died
NOT even bench it to see how it does... :(
oh :banana::banana::banana::banana:
that is just terrible
:(
Hi all,
Any reports if this Elpida kits are dieing to?
A DATA Triple channel 2133X "ELPIDA"
Thanks
A-data 2133X are elpida hyper based, not sure about the recent batches as not many folks have access to purchasing 2133X
If its elpida hyper based modules they will most likely degrade/die the same way as any other manufacturer...
I saw it here:

Is elpida, but I don’t see any reports off this kits dieing
My adata kit 2133 3x1gb died....~2 months ago......with 2.1V:D:p:
I'm very lucky, corsair sent a set of GT C8s during the time when elpidas are always out of stock, great sticks not the top binned c7 but who cares right? those sticks doesnt seem to wanna die , anyone got the sticks during that famine period, should be durable ones?
even though i still use micron d9gtrs every now and then :P
Shamino & Chispy - what does the code on your sticks say? This tells you what week/year batch they are. Seems ones made in late 08 and early 09 my be more resilient, for Corsair sticks anyway.
Code will say for eg: 0847XXXX = week 47 2008
Cryptik , My code on the sticks said 09051724 , so my guess is week 05 2009.
Angelo.
I got my 3x2 1866 dominators in the AMD rig now. Tuning them in atm hoping for 1760+ 6-6-6 1.7v
Dare me to run 32m?
Double dare Chew* !!
My kit, DominatorGT TR3X6G2000C8GTF back of RMA few days ago.
Still running well too.
batch #0927xxxx
any chance of not being Elpida hypers? :D
my 2nd stick been running well for 3 months 24/7 at 2k 7-7-7-20 1n 1.6v
already burned more than 100 hours of prime blend and 20-30 hours of linx.
i do test it once in a while.
never offed the comp .. only left it in sleep mode. usually if any errors on it will have sleep mode wake up issue.
first sticks no prob actually other than it not being able to run at rated voltage.
http://www.pcworld.fr/files/61031-g-...F4LTk4MHgw.jpg
Those Gskill PS seems to dont die too , some month i m benching with it. IC's are mix of 848 and 849.
There still seems to be a bit of confusion as to exactly what chips are on the terminally flaky Eplidia Hyper kits...
It seems to me the affected Hypers have the code (on the actual chip) of BASE
My cheapo G.Skill tridents also have Elpida chips but the code is BBSE, hopefully this means they are either not Hypers or are differently binned / a different batch.
Either way I can boot into Windows at will :D (for now...)
I think I can stress them quite well ;)
Still a work in progress. I will say I found some oddities, exploring further before I comment.

More Chew, we want more :) MM is testing the blades on the P55 right now...
I've tested the Blades on the AM3 a long time ago - 1400CL5 and 1700CL6 1,65v.
But ssshhttt: Leeghoofd doesn't want to know :p:
Only issue was the poor quality of the IMC on this 720BE, so I was limited by cpu anyway. Didn't try much more voltage, never went over 1.7v iirc. 2x2GB is correct.
No issues, to be honest, never had any so far. I really love this kit :D
Interesting, run 32m by any chance @ 1.7v?
Reason I'm asking is at same speed above @ 1.7v = fail, Memtest passes @1760 +.
I think I'm gonna break out my mach 1 to get to the bottom of this, seems all to familiar.
Fail due to too high clocks or voltage?
Nah Dropped cpu speed and nb speeds and voltages down......still fails 32m with 1.7v at same speed, passes at 1.65v fails higher than 1720.
It gets stranger I can do whatever I want at 1720, Like crank down on all sub timings but can't pass 1720 and can not give more than 1.65v.
Now we had a 3x1 g kingston kit that we could clock higher with and give rather excessive voltage to.....
I think you know what i'm getting at here. I'm on air atm, will bring some cold into equasion in a bit.
Tightening subs. Like 10th run so far I think. Still alive and kicking,
http://chew.ln2cooling.com/elpida/elpida%202.JPG
EDIT, think I figured out a way around part of the problem....
http://chew.ln2cooling.com/elpida/elpida%203.JPG
I was actually going to suggest that: drop the NB frequency :).
The big problem with AM3 memory overclocking really is the quality of the northbridge. First of all, it's not necessary to have high speed memory if you're not using a high-speed northbridge and, secondly, the stress put on the northbridge by running high clocked memories is enormeous. Have you seen Titon's 940MHz+ memory speeds? That's only possible because he was running a 955 (better silicon quality) ánd, very important, had his cpu run under phase.
You'll notice, by the way, that there's not a lot of scaling in performance going up even higher in the memory frequency. You might want to try CL5.
Not sure what this has to do with the Elpida's dieing on everyone.
Well nah it is off topic, but I'm hammering them with 32m to A: make sure they are going to hold up, and B: break the myth that they will die if you run 32m...I'm sure they have issues, but I don't see any AMD guys with said issues.......
I tried 1500 5-5-5 in pi and a few other benches when doing the review for the 955, utterly useless at 6 gig +........my gskills smoked them 9-9-9 1700+
These are going to be for 3d only.
The NB can handle that speed, Just dropped for now to eliminate it from equasion, ram is ramping up now due to some adjustments was still failing with lowered NB prior to adjustments.
How high was your northbridge running at 6G+ runs? I bet higher than in the screens you're posting now. That's what I'm talking about here: low NB frequency and you don't need high frequencies on the memory to have good performance.
Can you run 864MHz CL6 with 2.8G NB on air cooling (as in same temps)?
As for the myth; it's obviously a myth. There's no such thing as 32M killing memory :p:. Has anyone made a list of the motherboards that killed the memory?
Was 3800 + NB
Ahh, yah at 4 gig and 2600 NB I saw no benefit over ram speeds. 5-5-5 kicks ass.
I'm not tuning these for 4 gig though :p:
Yah thats what I'm getting at is it certain boards and or just plain intel boards, I'm on my 15th 32M run still no dead sticks.... I think its a combo, elipdas design flaw, intel board voltage implementation? Maybe a voltage spike at boot?
You're wasting your time with 32M: it's just not the reason why the memory gets killed.
As far as I can see (and I've heard), it seems that Evga, Dfi and Asus are mentioned the most. Then, the obvious question would be: why not MSI, Gigabyte or other manufacturers?
Because the first 3 brands you mention are used by the majority of the Elpida hyper users perhaps? I do not think the board matters, its the dimms it seems. I have had several sets on Evga, Asus, DFI and GB board, First dead dimm this week :( New kit, installed OS at rated clocks (2000mhz @ 8-8-8 1,65v) reboot, set 1600mzh for test and no boot. 1 dimm = dead
It's possible that the explanation is indeed that simple.
What board were you on?
I second that George :up:, as per my own experiences with Corsair DominatorGT 3x 2GB cas7 2000 , i have run this modules in DFI , Asus , eVGA boards over 1.85v V. Dimm used and abused for looong periods of benching and they still like brand new , my elpidas hypers wont die after so much use and abuse , no degradation that i have noticed either. The problem its the bad batches of Elpidas Hyper not the boards.
That actually sounds as the best fitting explanation :)
Well you have not seen the bucket I have under my desk then for the Elpida recycling project. ;) They fail on AMD, Intel, NVIDIA, does not matter. It simply comes down to the quality of the IC, said it a long time ago, still saying it today. We have identified the suspect lot numbers with the help of the memory manufacturers, just waiting on Elpida to respond.
There is no myth about it being 32M per se or any other program. Seeing as the memory only sees this as data and address values why would 32M be any more guilty of memory manslaughter than any other software? Some batches are just plain weak and it does not take much for them to keel over. ALthough I joked about this earlier, yeah the power factor will be lower on AMD as power draw is determined by frequnecy, current, voltage and operations per second - even still, the weak sticks will still die regardless of platform or board.
Anyone got any of their elpida back from rma yet? Just wondering about the ic's they got back if they are holding up. Still holding out with two stick until august when kingston is suppose to sub out a different ic on their ram.
hey george you sure its not just your classified not likeing to boot cold with these sticks j/k
i havent played with my 2000GT CAS7 kit on Classi yet and just put it in tonight
NO BOOT
:banana::banana::banana::banana:
lol
it turns out that my board doesnt like this RAM and i have to boot with 2xsticks and then apply settings power down and put the third stick in
i just spend half hour with this and i've finally got it in memtest showing 6GB stable
i dread clearing cmos lol
Yeah its not limited to the Classified or 32m as both my sticks died after normal use. Shut my computer off just to turn it on the next day and 1 stick be dead on both sets. One set died on my DFI while the other on my Classified. One set was HyperX's while the other Blades. I have noticed that the ones mainly dying are GT's, Blade's and HyperX's.
yeah i killed my C8 kit on Gigabyte UD5 but i did play with Andre(w)esque style voltage :D
yep saaya, same speed with 1.7v = exact in round or any of the other misc errors you get failing 32m. Tried undervolting same thing. No clue, weak stick maybe.
I have a set of d9's like that that should have been rma'd but they do 1800+ 7-6-6 undervolted so I kept them.........
Here's 1.7v :shrug: cpu and NB both eliminated from equasion, gonna try one stick at a time now...
http://chew.ln2cooling.com/elpida/elpida%206.JPG
1.65v also take note this board undervolts.......
http://chew.ln2cooling.com/elpida/elpida%205.JPG
Well for whatever reason 1 stick has no voltage tolerance whatsover.....This might be part of the issue, maybe sticks losing voltage tolerance over time :shrug:
Just clocking ram, I swapped to a diff cpu as well will toss everything in the mix in a little while, still searching for max speed.
http://chew.ln2cooling.com/elpida/elpida%207.JPG
OK max ram on AMD at "safe" voltage if there is such a thing.
http://chew.ln2cooling.com/elpida/elpida%208.JPG
And this is my sweet spot it appears.....Will keep them at this speed and report back if and when they die.
http://chew.ln2cooling.com/elpida/elpida%2013.JPG
Just had another stick of Kingston HyperX go belly up. This stick died in windows after a boot up. Since i now know what it looks like when they die from the other stick. Rebooted slapped in the old trusty memtest86+ and sure enough red errors all the way down the screen. Now the sad part is i'm coasting on 2gig here and frankly i feel like i'm waiting on a time bomb now. KIngston got me scared............
Hey people! After these big mess with the Elpida Hyper I dont know what memory should I buy... I was going to buy a Dominator GT 2000Mhz Cas8, but I dont want to spent like u$400 to see how they die in a few weeks. So... what memories do you recommend me to buy and not to take the risk of see them die? I live in Argentina, and I have to ask someone to bring them, and if I have to make a RMA, it would take months till I have the new mems...
So, that is the question, what mems do you recommend me to buy? I will buy a EVGA Classified 760, so, I will like a good pair of mems to complete the rig :) A friend tell me that Corsair mems have issues with this mb, is that true?
Well, thanks for all if you answer and sorry for my bad english.
Thanks a lot for clearing my doubts Yellow! Ok, it seems that I will put some basic memory and then buy a really great kit, wish this nightmare finish quickly so I can go directly to the Domis GT.
Thanks a lot Yellow and congratulations for the great work!
Currently I'm running my second TR3X6G1866C7GTF kit after the first failure.
oc @ 2000MHz 7-8-7-20-1T Vdimm @ 1.72v, qpi/vtt @ 1.65v, Vcpu @ 1.39v.
With the above settings I ran successfully hyper pi 32M, memtest for windows 500%, memtest86 5 passes stable and linx 5 passes stable.
Also I noticed that sometimes when I used lower vdimm values @ the post process only 4 giga where recognized from the 6 total. Rebooting raising vdimm and 6 giga recognized again. I remember another thread about dropping ram channels. I don't know if this is a bad sign of feature failure.
Using a dmm and measuring vdimm @ full load I noticed that the mobo undervolts the dimms by 20 mv.
chew, i experienced this over and over... thats the ceiling of the memory or the memory controller... whenever i pushed memory to the max when working for cellshock, regardless of what chip, it would always act like that when i hit the ceiling... itll not clock higher and vdimm wont matter and more actually makes it worse... if you make a graph you will see that it kinda bounces against the ceiling at some point, with increasing vdimm it goes into a sinus curve bouncing against the ceiling, or, it drops down bit by bit, or, it starts falling big time to very low speeds... ive seen all of those possibilities with the same memory chips from the same batch even...
but they all, always had one point at which more vdimm didnt help and started to make things worse.
btw, i had a strong suspicion back then that at least for micron chips pushing above vdimm that had them stable through the chips damaged the chips after some time. i always used memtest86 and kept vdimm at the level where it was stable for that speed and that timings, and those sticks never died for me... the only ones that did where the ones where i forced speeds higher and higher in windows with more and more vdimm, ignoring that the mem was actually unstable and just pushing more and more for suicide shots.
oh and yes, diferent timings mean more vdimm is possible or you get errors at the same vdimm that was ok before... in general in my experience tighter timings at the same speed = higher vdimm accepted by the chips. for micron cas and trp made a notable diference in how much vdimm i could pump through them, which then meant i could get slightly higher clocks... but those are tiny things, 4mhz more and 1 step higher vdimm...
corsair compatibility tends to be very good, but i dont think they referred to compatibility here, a couple of people seem to be unhappy with memory tweaking and overclocking on the evga board, not sure what exatly though as nobody mentioned any details...
Add my Mushkin 6gb redline 2000mhz cl8 kit to the graveyard haha. Just died on me. The stick in DIMM1 just failed. I was actually looking at XS and it bsod'd on me and it has never happened with this kit, and it said something about anti-virus in the bsod, but I knew immediately what to look for since I've been through 15 kits of Kingston. This kit of Mushkin lasted much longer though. I've had it running strong for about 2 months with no problems, much different story than the Kingstons. Oh well, I guess, elpida just sinks farther into the hole they dug for themselves. First japan has to bail out elpida, now as if things weren't bad enough, the hyper chips are flawed and manufacturers are returning them in masses.
could you repeat that? it sounded like you had 15 kits kingston elpida hyper die on you? :eek: maybe its a typo? :o
about japan bailing out elpida... hah!
the irony goes deeper, japan bailed out elpida who then almost bailed out some taiwanese dram makers, but the taiwanese government put a stop to it from what i heard... funny eh?
help we need money to survive!
then take the money over seas and invest it in another company LOL :rolleyes:
just another reason why im against all those government bail outs...
i dont think this hurts elpida at all... the chip recalls are probably peanuts for them... what they really lost, and lost big time, is credibility...
i wouldnt have expected them to have so bad Q&A and then not even having the b4lls to stand up and admitting a problem... :rolleyes:
oc @ 2000MHz 7-8-7-20-1T Vdimm @ 1.72v, qpi/vtt @ 1.65v, Vcpu @ 1.39v
how far of an OC does it take ???
at stock speeds and voltage are the sticks failing ???
Pushing ram speeds at low volts with ICs becoming very small I bet is not an easy task. Then people like us OC/abuse the sticks and then they snap and fail thus being the companies fault???? My CPU ever fails it will be due to my voltage and OC I put on the chip.
The company and the consumer should bear the responsiblity
Yes, some users have sticks dying using voltages that are below stock. Something is certainly amiss, perhaps the real rated voltage and speed of the IC's is a lot lower than what Elpida or the vendors applied, or simply issues in fabrication and quality control. All parts of the jigsaw I guess.
Does anyone have a kit of Corsair 1866GT's (or 2000 C7 or C8's) that are week 26 of 2009? (IE: the code starts with 0926). If so how are they going?
This is the second kit TR3X6G1866C7GTF I'm using. With the first one I lost one module and everything was at stock. It's been a month now since I started using my second kit without any issue.
No, at stock speeds and voltages the stick don't fail.
The above setting were the minimum I could use to keep the system stable and they are safe:http://www.xtremesystems.org/forums/...34&postcount=1
Corsair also in its forums suggests a qpi/vtt no more than 1.7-1.8 volts.
Paying such a high price you do expect more.
Of course everyone is responsible on what he does.
10 died on me, 5 were doa kits from newegg, probably the very same kits I was sending back. Only around 10 kits died in my hands, but if you looked at neweggs records, they probably would say that I killed all 15 haha. They never really understood what was going on. I kept telling them it was a common problem of the chips dying, but this was early on in the game, well before anyone on here had reported the hypers dying, so they thought I was just an idiot who didn't know how to install ram or adjust voltages. That's what you get for ordering 7 kits of the stuff haha. I couldn't have picked a worse set of ram to buy a lot of. One by one the dominoes fell and each kit had to be rma'd. Thankfully for my wallet, newegg paid the return shipping. Each kit was rma'd once, plus when I sent a kit in for refund, they sent me another doa kit back for no apparent reason which makes up the 15th set. Many hours of customer service later and I've got all my money back. Now it's on to the mushkin customer service department.
Your 100% correct , i also experienced the same situation with newegg, and was 1 of the first to buy these kits too.
Their policy is to resell the returns no matter what,you must of got mine :rofl:
I also wrote bad stick and do not resale on sticky note ,and taped it on mem stick,and i also called the supervisor to take them off the shelf.
Yeah, as soon as I started getting open packaged ram with tape sealing it shut, I started thinking hmmm... these look mighty familiar, then to test them and find 1 stick doa, I realized, aha newegg is just sending the junk ram back out. I even told the customer service rep online, I've gotten multiple packages that are open and doa, you guys are just sending the same ram from these rma's back out. Of course she ignored what I had to say and asked me what the symptoms of my computer problems were. Do you have the ram inserted right? Does your motherboard accept ddr3? Are they in the right slots? And every time the answer was the same, guys, I'm an overclocker, if anyone knows how to spot dead ram, it would be me.
what about a KHX16000D3T1K3/6GX today? did kingston find out a solution for sudden deadh issue of his memory?
Same question here.
I own a Kingston HyperX T1 6GB and one of the sticks just give me Radnom BSODs and crashes, regardless of the speed (even at 1066 CAS8.)
What chips are we going to get in them if I will RMA the sticks ?
i'm rmaing my dom gt and i asked them which one they'll send back, i'm waiting for their answer
will let you guys know the answer
Add me to the list. One stick of my mushkin 998707 died last week. I was running it at 1800 7-7-7 1.65 so I wasn't pushing them hard. Still awaiting my rma #.
Posershadow: did you deal with newegg or mushkin for your rma ? If you dealt with mushkin ,what replacement set did you get ?
Well those original sets were kingston. That was all through newegg. My mushkin that just died is still in process with mushkin, I was late sending them in, getting lazy after having to go to the post office so much for all this elpida haha. No replacements yet. Hope they don't send me more bad elpida.
Well one of my sticks went dead last Sunday. It was Kingston's.
Before it died I tried 1.48VTT and 1.72VDIMM along with Corsair C7-1600 Ver 2.2 for a 12GB 9-9-9-24 2000Mhz 1T Testing. After that it just died out.
What I've seen is Kingston has been replacing these kits for a new model. Let's hope that new verison will solve the issue permanently..
EDIT: Oh one more thing. That dead stick just won't boot up or recognize. However it will boot up just fine with my Rampage Extreme and I wonder what's wrong...
