Any more info on those samsungs? Have you tested them?
Well, some D9JNL are certainly not bad :D

if a product has been out for a month or two i personally dont see any point in hiding what chips your using tho...

My arguement still havent been discussed... and fact is people are killing their ram with BELOW stock voltage...

PLEASE read my previous post and LOOK at whats being stated before replying to this post... Because obviously, evidence doesnt mean a jack@ss
1.5v killed ddr3?
link?
maybe a bad psu voltage spike or installing into a machine with the power on.

I'd find it WAY more likely as I've stated that its not voltage, but a TIMING, a setting that injuires the ram...! Because if it was ram, and we're talking same chips here.... Dont you find it a little funny that someone injures their ram at 25-30% less voltage then others run without hassle? Well I know that I do... Further, from the DDR2 we saw same tendency, with timings, other factors having severe impact....
I think its completely BS to call "ohh its voltage"...
And from how I read the post I've linked to, I see 1.7v killing ram, GTR, I know people that has ran 2.8v without injuring their GTR... thats more then 60% higher voltage.... Now I just DONT belive that can be coincidence...
Ofcause the rate of electromigration is effected, yes, but thats not meassureable for us normal consumers... And I dont think the impact is that severe...
i think this deserves some more scrutinyQuote:

you mentioned drive strength in other threads but we don't you tell us something we can understand. What are you talking about exactly here :)
Ihh, I'll explain later :)
I'll add some BIOS photoes, sadly Im sitting with my laptop... I could write the entire reason, actually I just did, but deleted it... Its just not usefull... (2 dead moboes, plus I've borrowed alot of HW to a friend thats hunting danish records with 2x HD3870X2)
I'll post pictures on saturday if I get the time... I wont be at my adress with the HW before then...
We (Oliver, THC, and myself) have 3x X3110, 1x QX9650 and want sub 8s 1M, PCMark2005 WR, plus 10 3Dmark WR's (x19xx + another class), so maybe I wont get the time, but I will try!
tell us what bios settings you are talking aboutQuote:

He's talking about DRAM Drive Strength ( usually found in DFI BIOSes... )
It's a repeat of the conversation from the UTT-BH5/UTT-CH5 era again.
As a theory it was "ok", but in practice... people have killed chips with light & strong Drive Strengths and the same voltages... so-so.
i agree with you BZ
Drive Strength in AMD days wasn't really as big a killer as some guys were making it out to be
That is correct... : - )Quote:

if you want to go on doing this then PLEASE stop posting in my threads and make your own, THANK YOU!
now back on topic, as many of you noticed, micron ddr3 can take higher voltages, or, likes higher voltages and scales more, with tight timings.
with tightr timings the mem is working harder, and can suddenly take higher volts. at the same time with more relaxed timings the mem is unstable at lower volts, which makes you wonder if its just unstable, or if its actually getting hurt/damaged from the volts sooner if its running more relaxed timings. i dont know how to explain this... but the timings seem to have an impact on what voltages a kit can take. from what ive seen its a very small impact though and it wouldnt explain why 1.7v killed mem even if it was only at 1333 and 999... i suspect it was/is a bad stick, bad mobo, bad psu, or maybe ESD damaged the stick and then it failed immediatly or after some time in the board.
You have a point there Saaya.
Oh, by the way: "Tight timings, high voltage & higher current draw" ;)
I have yet to get past 2.29V on DDR3 ( and that's because I want to keep those 2 good kits that I have here alive :D ).
However...when I get... another kit....and the time to do some tests... I will be exploring the voltage limits :D
To ALL.
OCZ Gold is low to mid range ram, it may or may not be Micron based from us.
Platinum, Reaper and Flex are high end parts and feature high end IC's. All Platinum 1600 and higher is Micron based. Some Gold may have micron as some have seen as we shift so many IC's some just gets used up on lower end parts...there is no guarantee it will clock high though and you may get qimonda or elpida.
Also I hear talk of D9JNL, OCZ have been using this IC for 3 months now, its not new as some think, its been out a good while.
hope this clears a few doubters minds up ;)
I can't see how you can pass judgment on a subject like this as you have no idea about damaged quantity, only someone working for a module manufacturer would have any idea.Quote:

There is sooooo much you guys are unaware of its untrue, issue is I can not tell you ;)
have some info for you:

No offence, but the only reason you can get away with a comment like this is because you work for OCZ, you're highly respected and have always provided the community with quality information. However, I don't see why you would not share information that would help people not to kill their memory. That would benifit both the user and the manufacturer, isn't it? :)Quote:

m.beier, ive said it dozen of times... there is no way to say xx and yy and zz combined will kill your memory. there is absolutely no way!
even if you would kill hundreds of chips under whatever conditions and then come up with a formula of x and y and z etc and all the parameters that would, for a given configuration, kill the memory. there would be memory falling out of that formula and you would be proven wrong.
there IS no safe way to say what will kill/damage the memory and what will not.
the point of this thread is to give people as much information as we can, so we can at least have an idea of what configuration and parameters CAN cause problems. this doesnt mean there is enough info in this thread you can use to be 100% sure your mem wont fail. thats not the point...
as soon as 1 person realizes hes on the edge and changes the settings and safes his mem that way, then this thread was worth it!
and if you ask me, there is enough info in here to prevent a lot of people from damaging or killing their mem. and the biggest gain might not be preventing mem from dieing, but people at least knowing they are entering a mindfield with certain voltages, and dont end up with dead mem without ever knowing they were risking it to die.
saaya, i work with partners on all sorts of issues, nothing to do with ddr3 dying etc...this is what i was meaning. So much happens but I just can't tell you as I can't....im probably so deep under NDA's and working agreements it would take a week just to dig my self out the 5h1t.
You guys know i will help keep your ram alive but I was talking about a MUCH bigger picture...MUCH MUCH bigger LOL
calm down guys please.
well tony, i know what you mean but then DO keep it to yourself...
you cant really wonder why people arent too happy when you tell them
"I know so much cool stuff you guys dont know, but oh, i cant tell you ;)"
i mean what kinda replies to you expect to that?
the context was not that at all, read my post again. I was quoting the forum world Vs the real world and what goes on, nothing more, nothing less.
Jeez you guys are way to critical, maybe I should not help in future

So my personal oppinion is; "yes", I do think you should stick out of the section, along with all other representatives that has to be concerned about warranty etc....

Apart from that, Im really pleased with the pictures of datasheet you have posted, I dont have that .pdf myself... Where can it be found...? Is it material send from micron to the memory companies, or?

m.beier, i see what you mean, but i dont agree.
exactly since this is a place dedicated to pushing hardware to the limits, imo its important to share where the limits are, so we know where the "ceiling" is and can "dance on the ceiling" without killing that much hardware. I would have made this thread as well if i wouldnt work for cellshock... i actually would have posted more infos, and i think the same can be said for tony.
if you prefer to find out for yourself at what point your hardware dies or gets damaged, then just ignore threads like this...
why do you keep posting here and in other threads telling everybody that you dont like the threads? just ignore them and make your own threads then... :stick:
:( Hm - so You can turn it to the left - turn it to the right, we all need DDR3 RAM capable of more volts without damage.....;)
Most of the today's available kits need 2.2 - 2.3 volts to show their whole performance but thats not safe anymore.:(
itll always be like this... if the max 24/7 stable voltage a ddr3 chip can take would be 3v then we would see the best results with it at 3.0-3.3v i think :D
unless they build the chip to not scale with high volts, and in this case we are stuck with chips that can take 3v but only scale up to 2v... so... either way, i dont think theres an easy design fix for this :D
sorry, i forget this thread , in Cas 7 1800 before i hit 2.3v for bench, my was run stable at 1800 7-6-5 2.00v, but after i run that voltage, more one week my ram was not stable 1800 7-6-5 2.00v i can try 1800 7-6-5 2.1v but is too high ....in 1000MHz i can reach boot now, not for windowsQuote:

:cool: Hm, I think it all depends on the quality of the chips. But sadly You'll never know before..........:( .
My first DDR3 kit was 1800 Cellshock and for benching I used 2.23v real.
Last Year I thought that's save....., I didn't kill them but I degraded them so that in the end there was no stable run at default speed & volts possible anymore.:down:
really? you degraded it with 2.23v? are you sure you didnt try more?
What board was that one? did you meassure vdimm with a dmm?
:rolleyes: Was on my Maximus Extreme - Vdimm measured with multimeter.Quote:

:shrug:
and how did it degrade?
what was the max clock before and what is it now?
are you sure its the mem?
maybe the cpu or chipset degraded?
or with a new cpu or bios or whatever you can reach the same clocks?
I have a casualty to report:
Team Group 1600C7 - D9gtr - 7MB12 KFGB.
Benched up to 2.275V (mobo limit). Not much of a performance increase though, so mostly @ 2.15V. Always with a fan direct, ambient ~24C.
Pretty quick onset, only saw minimal degradation ( 925 - 900 MHz @ 2.15V for 3D)
One MAJOR caveat: Board is 790i, mcp/northbridge used for extended periods @ 1.55V (max).
put up with about 2 weeks of abuse.
anyone have an idea of cold bug temp for rams? :D I may need to make a 'safety' LN2 pot :cool:
sorry to hear about your loss :(
so now they degraded or are they dead?
do they still boot?
you only used them for 2 weeks? or only for 2 weeks with high vdimm?
-40 celsius works without a hitch, dont know about less
i know ddr1 and ddr2 dont like to boot at temperatures below -80 degrees or so... ask jmax, hes the king of frozen dram :D
:cool: Used them for 2 or 3 month, they were not dead but instable caused by degration. 2.23 Vdimm was used only for benching, but after that I went into stability problems.Quote:

where did you meassure vdimm?
Well actually, I think you need to read on your micron specs... Can you please find that statement on their page?Quote:

i think you need to finally stop threadcrapping with your "know it all" attitude.
and then maybe read my post again, i didnt say anything about the official micron specs.
:( Sad to hear this, degrade with "only" 2.23v.Quote:

Yeah, I must also report Degradation on my Sticks...
Bought them in Feb, been running them since 24/7
First 1.9 at CL7 were no problem now they want moore!
allways got it around 2v, and some benching at 2.28 at highest, but for short whiles...
they managed CL7 ddr2000 at 2.28 pretty good before, today i just wanted to try it on this p5e3, and WHAT? not even with 2.40 did they enter the OS.. omg.
2.30 were no post... they have gotten pretty bad i guess 2.12 atleast are needed for some game stability at ddr1870 CL7.
Lately i've been using around 2.1v, but i just raised it couse they were instable... allways had it at 2.0 - 2.04 or even less.
what to do what to do :) , and no saaya wont RMA them ;)
i probably will buy the blue ones instead, JNL chips, seems to require some less voltage too.
regards.
infa, try them in the same old board as before, maybe its just the new board that either sucks, or, doesnt work well with this particular kit.
ive noticed a lot of weird compatibility problems like this. some kits will clock way better in some boards than in others...
since i bin them with a big margin left to oc, so far all kits seem to work on any board, even if they are a bad match, but when ocing you can def tell a difference from one board to another.
just ask 3oh6 and benchzowner, they made the same experience, some kits suck on one board and rock on another, then another kit will rock on the first and suck on the second...
ddr3 is still quite freaky and "untamed" at high speeds and voltages :D
here is a graph about some tests i did:
http://www.abload.de/img/board2vs3im9.png
left is onep5k3 deluxe board, right is another p5k3 deluxe board.
colors are sticks, top lines are cas8, center cas7, bottom cas6
memory divider and strap were always the same, same bios, same everything.
you can see both boards are limited for cas8, but the board on the right is limited way more than the left.
and it doesnt just cut out at one frequency... it clocks the mem worse at cas8, and even worse at cas7.
note that the right board clocks worse with cas7, even at 1.7v!
and note that there is not always a strict line that no stick of mem will be able to pass!
some mem can clock higher, but not much, they will all be greatly limited in cas8 and slightly limited in cas7.
I hope this helps :)
oh yeah, that too, make sure you use high enough chipset voltage, and use the slots 2 and 4.
i made a test on an asus maximus extreme regarding channel 1 and channel2.
very interesting results, on channel1 more chipset voltage than 1.5v didnt really help, and i could only use rather low vdimm. more vdimm and it became unstable.
plus the vdimm tolerance window was very small.
channel2 worked way better, the vdimm tolerance level was very wide and worked from lower to higher vdimm stable than channel1.
with channel 2 i could push 50mv more vdimm and still have it stable, compared to channel1, which obviously allowed me to clock the memory higher.
not much, only 25-50mhz, but not bad...
plus on channel1, there are weird compatibility problems when running dual channel... the sticks have a higher chance of not matching well as a pair.
ive seen as high as 300mhz difference from max stable in channel1 compared to channel2.
i hope this helps you to maybe get your kit stable at high speeds again infa.
i cant really believe that 2.28v damaged your kit...
EDIT: here is a graph:
1 = no boot
2 = freeze
3 = memtest/orthos errors
4 = memtest/orthos stable
http://www.abload.de/img/vmchvsvdimmvsslotsi4e.png
Very interesting results... I don't understand the last graph though, the key is what, vDimm? But x-axis is also vDimm?
x = Vddr ( Vdimm )Quote:

yes, and the colors are vmch, yellow = 1.5v orange 1.6, dark orange 1.7 and red 1.8v
that way you can see how more vmch makes higher vdimm stable in dual channel, which in return means higher stable mem clocks :)
EDIT: one more thing i noticed...
sometimes, the sticks will work almost stable at least say 1850 mhz... but when you go lower to 1825 or even lower... the stability gets worse!
that happens when a stick is close to beeing saturated on vdimm and doesnt like any higher vdimm.
the lower you clock it, the less vdimm it will like, and the more unstable it will become with the same vdimm.
Ah :D That explains. Cool thanks :D
I think I just killed a pair of Kingston D9GTR at 2.12v. No joke. :confused:
what board are you on
do you have DRAM VTT as an option on it?
Reference 790i. It might be the board being retarded all things considered though. It's done 1080 8-7-6 for a month now easy almost every day, with voltage no higher than that. Then yesterday I felt like trying a 32M, failed on the first loop even down to 1026, and poof, ram seems busted.
I'm crossing my fingers that once I drop it in a P35 it'll be back to normal, but somehow I'm not hopeful considering my luck.
have you backed down with volts and lower clocks?
790i boards can be funny beasts so it could be something else as well
fingers crossed they are ok
pretty sure you have a nice set of sticks
Nah, I was too irritated so I just went to bed. :D This morning for some reason 1070 seemed okay for 3D once, but it had to be unlinked with some goofy divider like 14:30. Then after that it started acting up again, and having trouble POSTing. It used to be fine sync at 540 FSB, so either the board or ram are going south. :S Problem is that only 790i is capable of clocking the ram that high so it might hard for me to verify for sure what's going on...
Hopefully it's a false alarm. (I'd probably actually prefer a dead board lol) The suddenness is what's weirdest about this. Not gradual at all, working fine for a while and then a sudden dramatic fall in speeds. :shrug:
i wouldnt be surprised if 790 has a higher drive strength than intel chipsets, same as with ddr2, and as a result kill memory at lower voltages?
or maybe the vdimm regulation on 790 boards is just as unstable as vcore? :D
did you check if both sticks are affected?
did they ever run 100% stable at the speeds you ran them at?
what spp voltage are you running?
maybe you damaged the memory controller and not the mem?
and a setting working one day and not working another... well.. thats nvidia chipsets for ya :D
It is busted for sure. Tried it in P35 (Blitz Extreme) and it cannot even do 950 CAS 7.
Dunno about the individual sticks, good idea.
If it's 790i, then how does 3oh6 get away with running 32M's all day every day at 2.15-2.2v? :p:
This is beyond explanation, I don't think it's even the voltage that did it, but there's no sensible cause I can pin on this whatsoever.
Either way, the moral of the story for me is, it doesn't pay to be a pansy. :p: If DDR3 can die at 2.1v, it will die no matter what if you oc. My next set is getting 2.4v straight up. :D
Just saw that Adata has Micron based DDR3 kits that are warranted up to 2.15V. So that is supposed to be safe :)
haha, hell yeah man! i too have been like you and going easy on the volts but now...who cares. if they are going to die, let them die. i still won't be throwing 2.4v into them for anything other than a one-off record run but i am certainly not scared with 32M benching all day at 2.15~2.20v.Quote:

i might be moving over to the Maximizer on the 790i though to see if the voltage regulation on that board is as bad as i think it is. i just have to get off my but and do the soldering.
I killed two more sticks a couple of days ago. Ballistix PC3 12800 this time, also at 2.1v, in very much the same fashion. It isn't voltage that's doing it. I have other sticks that continue to run strong, even on the same board.
The common thread I found between all the dead sticks is that I was trying to push them to speeds they couldn't handle. e.g., I immediately tried 1100 8-7-6 right off the bat. They failed to enter Windows a few times, then Windows got corrupted, I come back a couple of days later and one stick won't even POST, the other won't even make it into windows at 1000 CAS 8. This is more or less how all four sticks that I killed, Kingston and Crucial alike, died. Maybe you'll think I'm crazy for suggesting this, but it seems like the cause of death for all of them was instability. :S
far out man
more dead sticks :(
i too did a lot of big jumps like that and even used max volts in bios >> 2.275v i think for some sessions but the sticks are still running ok
maybe your board had messed up RAM circuitry or DRAM VTT is waaaaaaaaay out of spec or something
I'd think the same, but I still have several sticks going strong well into the high 1000's CAS 8 with the same voltage on the same board, even mustered up the courage to do some 32M on em. :p: A single stick breaks 1100, now I just have to find another one to match it. :) (Trembling yet, Jody? ;))
The ironic thing is that I have a gut feeling that more voltage might have actually saved the others. O.o That way they'd have been more stable. I think the only moral of the story is that assuming that a fresh untested set of ram can do 1100MHz at 2.1v is a bad idea. :D I don't know how instability can kill ram. I remember a few years ago that people were killing Radeon X800's by running the raw clocks of their memory too high. This might be something similar, but you're probably right in that it has something to do with the board. :S
Now we're getting somewhere :)
I cant say I dissagree on this, I still belive that vdimm isnt what to be blaimed...
The question is just, what does cause the killing...
As I told Gautam some hours ago (I probably didnt make much sence, was LATE night in Europe)
I still havent managed to kill any, and I've not been very kind to the ram.
Back again... sorry havent answered you saya :) easy to forget these PM's.
now i think they have degraded even more, havent used my comp for 2 weeks~ and now after 2 days i decided to play again..
and crysis crashed AGAIN... sure that game crashes alot, and have nothing to do with hardware, but sometimes it does..
and now it did, like before when i had to low vdimm... AND now it doesnt even pass first irretation of 32m anymore. As it did before, and now im at 2.14 at 934mhz Cas7
think thats to high, and now it want MORE , i really think they are degrading, and not the board beeing diffrent...hmmm.
Ok, think i made a Noob misstake... i was using to LOW vMCH!
omg , how can i not think of this :)
now it passed first 2 irretations without hickup....hmmmmm...
was keeping it at 1.51 for 1869mhz cas 7, with PL6!! and twister at stronger...
maybe i was to synical and thought it would work with 1.51 :P
will test more...maybe all the time it was the NB voltage :S
EDIT: failed...will try with more nb.
Edit2: 1.51 will fail 32m at first initial loop, 1.57 are better but will fail after loop 1, 1.61 will fail initial, 1.55, pushed to loop 7.
Edit3: PL7 and all channels pulled in, and 1.55vMCH passed 15 Loops, and then it hanged (ala Vista) :) so i take it as it worked, still same 2.1v at Vdimm, so it may not be the RAM afterall...hehe..quite tricky though...
Edit4: omg hehe.. they are a good way to learn these board.
now i tightened the ram timings even more, 7-6-5-16 , trfc 48! at 1869mhz PL6 fsb 467! keeping vMCH at 1.55, and i tried even to lower the vdimm, and imagine, i stopped it at Loop 9 myself... :) STRANGE, now im at 2.08vdimm.
i learn stuff everyday hehe. will comeback with some complete tests later.
regards.
maaaaaan these boards are weird.
gautam, the x800 mem corruption thing killed the gpus imc, not the memory from what ive been told. i have a feeling that if you feed the chips more volts than they can "process" they start to create errors, the more vdimm, the more errors. and if you continue running the mem that way it seems to degrade or kill the memory. thats my gut feeling about micron ddr3...
infa, yes, vmch is very important to get high mem clocks, from what ive seen.
more vmch will let you reach the same mem clocks with less vdimm in some cases, funny eh? usually intel nbs seem to scale up to 1.7v above that your barely get any higher memory clocks. but if you run tight PL then more chipset voltage than 1.7v actually does scale... thats why some crazy people like hipro went up to 2v and above and run PL5 and PL4 :D
I just lost by feeding ~ 2.35Vdimm:
a. One of my CellShock sticks
b. My retail Foxconn BlackOps
c. My ES QX9650 CPU (working at 3.6GHz with 1.25VCore)....
I honestly don't know what happent!.... :(
My CPU on my other mobo now boots up and stops at "C3" code..... :(
Though the other stick is OK......
maybe it was just a bad board that "took" them considering you lost a CPU as well donno
sounds like it... mobo or psu problem id say :/
That's bad George ... :(
Did esdee drop by your place recenlty ?? :shrug::shrug::shrug:
Hmm reconfigured my bios settings, now they only need 2.06 for 1870mhz 7-6-5-16 TRFC 48!!
looks like ME was the mistake, and ddr2000 booted and loaded win at under 2.20 ... seems like no degradation then... just me degrading in knowledge :P
i dont blame ya bro, ddr3 boards are tricky to tame :D
Setup the rig in my sig at 790i Launch day.... Been running the speeds in my sig since then, yesterday was VERY HOT and humid and lo-and-behold my RAM has degraded to the point of running 1777 8-8-8-24-2T instead of 7-7-7-21-1T like Ive had it since I bought it.
2.0V set in Bios 24/7 since March '08 (about 4 months)
hmmmmm so... all the sudden you can only run 888 2t and no longer 777 1t?
thats... weird...
whats the max 777 1t you can run now with the same voltage?
are you sure its not the chipset degrading or maybe some BIOS issue?
Haven't bothered to check highest 7-7-7 1T but I'm 99% sure its not the chipset since I'm only running 1.35V SPP.Quote:

My guess is the degredation is only very slight, still I thought worth reporting.
well 777 1t to 888 2t is quite a big degradation imo!
thats the difference between high end memory and value memory that costs much less :D
Are Micron the only known DDR3 chips suffering of degradation?
