EnJoY refers to "common" Micron D9. Those ICs in the FlexX in your sig have been picked and tested and are (hopefully) found to sustain voltages up to 2.4v. That's the theory at least. Why would they warranty them that way if they didn't for most? :P
Well, from my experiences, I wouldn't go past 2.2V for DDR2. (24/7)
I had some Firestix that were RMA'd every three months from running UNDER clocked at the recommended voltage of 2.15v. DDR2-1000 running at DDR2-994 using stock timings and 2.15v lasted exactly three months for me...twice. People blame my motherboard (P5W H Dlx), but who knows.
Well if it's rated for 2.35 then it should be at 2.35V for stock! I been running my Crucial Ballistix DDR2-800 with 2.4V with no issues!
Good luck with that.Quote:

i've pushed 2,55V through d9's for benching (with hr07 and fan on them) and they are still alive, but i woudnt run more than 2,3V for 24/7.
2.2V max and that must be DMM (not bios set). Listen to what Crucial says and think about who makes Micron chips :)
2.2V. But if you really think you'll actually see a difference, go as high as the warranty will cover.
It's the difference between 288 5-4-4 and 288 5-5-5.Quote:

No... 2.35v is the rated voltage for PC2-9200 (1200 MHz) operation at 5-5-5-15 timings. EVP is 2.35v... no +/- 5%.Quote:

my mushkins xp2-8500 are rated 2.35v
first 2 kits i was @ 2.26v 24/7 both kits lasted 2 months had 2 fans on em they never got warm to the touch
now i keep em @ 2.22v 4-4-4-12 1000mhz
my ballistix 8500 can do that with 2.1v and 1200+ with 2.13v
Asus maximus (ddr2) also overvolts by 0.08-0.1V! Same with maximus extreme (ddr3) - overvolts by ~0.06-0.08V. No idea why they do thisQuote:

I actually thought I killed those sticks during a bench at 2.6v, but nope, theyre still hanging on, just a RAID issue (used some different files from the driver set)
So even though I wouldn't recommend going over the EVP, it is there for a reason, I would expect safe operation at the EVP (2.35v) 24/7. Seeing how they're flex (im assuming you have them with liquid) then keeping them cool shouldnt be an issue.
LOL I see some people worrying about .1v overvolting, try 0.7 on my P5N32E-SLI.
I was investigating OCZ website and found out some interesting facts...Quote:

Is that mistake or true facts? If it's true, why OCZ gives for some series limits of voltage as basically they use the same D9 GMH and identical 8-layer PCB? :up:Code:**OCZ EVP (Extended Voltage Protection) is a feature that allows performance enthusiasts to use a VDIMM of 2.4V ± 5% without invalidating their OCZ Lifetime Warranty.
Did I hear you right, 0.7V? That's not normally possible. Minimum ddr2 voltage on your mb is 2.5V? lolQuote:

You are right, I stuffed up, .07, which doesn't seem so bad after all.Quote:

2,3v...my OCZ SLI 1066@1136(5-5-5-12)2,10V
1.8V is JEDEC std isnt it? :\
Manuf usually say 2.1-2.3....
End users who has actually tried and not toasted says.... If low ripple, stable volts, a decent ventilation (strap a 80 or 92mm fan on 'em) 3.0v for 24/7 use shouldnt be a problem... However, probaly wont benefit... I wouldnt mind using 2.8v for daily... (think it was 2.7v I used for 24/7 back when I used DDR2)
Nor would I mind using using 2.35v for daily on DDR3... and if it'll benefit daily, I'd might even go 2.4-2.5v daily...
But hey, I'm insane ;)
I used some Supertalent rated for 2.35v i was running them at 2.35 but they went bad so i RMA them then the new sticks i have them at 2.35 too but they gone bad too.So now i am using some G.Skill sticks at the same speed but with only 2.00v and i am Ok.
what? who said 3v for 24/7 isnt a problem? :confused:Quote:

the fact that micron IC die at high volts, but needs it to overclock (and they such good oc'er) does not help......
i run my D9GMH no fan @ 2.1V - 24/7
4-4-4-12 450MHz
6 months and still perfect

No seriously, 3V is damaging this kind of process technology for sure. There's no need and no sense in arguing. 66.7% overvoltage from spec can't be healthy.
From JEDEC.... HmmQuote:

run your memory at 3v 24/7, and run your 45nm cpu at 1.85 24/7 if you want, but dont suggest others that these voltages are safe. for how long did you run your memory at 3v? for how long did you run your 45nm cpu at 1.85v? ...Quote:

Still havent got a 45nm CPU, only a very few has been sold in Denmark, hopefully I'll get one before next weekend, and yes, it'll get all the juice motherboard can squease out... which sadly is 1.6v straight, however, I'll change mobo soon... And I'll use just as much vcore as it gains mhz, stable ofcause...
does these voltages also go the same with D9GKXs?
man that's some crazy voltage on these OCZ, how do they compare to Team or Crucial? any advantages? Also, does anyone have the link to the webpage that lists all DDR-2 manufacturers and the types of Chips they use in their RAM? It lists everything from A-Data to OCZ etc.
M.Beier your sticks are 1 in a million
i would not use 2.3v+ 24/7 i've had 6 dead sticks @ 2.26v ands sticks are rated 2.35v
Hmm I wouldn't say I've gone as far as M.Beier, but I have never had a worry with D9 running over 2.4v daily, even uncooled. And even my OCZ that I thought I blew up at 2.6v+ are fine and working again after a reformat (turns out it was RAID problem)
I think it is all luck of the draw, but if you run them at the recommended voltage I think you will be safe, if not then you can legitimately RMA them.
I have to say this is specifically why I bought OCZ. I know that if I stick to stock volts, and they die, they will RMA them.
So why do people worry about running at stock volts? I'm sure all these companies who have their D9 sticks with 2.3v stock know much more than we do. I mean, it is their money on the line.
Often you will see that if a person has had to RMA D9's once, then they probably have done so many times on that motherboard. Perhpas they're motherboard is chewing up the RAM (has been known to happen) but my P5N32E is notorious for being a D9 killer, yet I have more fun overclocking D9 on it than any other board.Quote:

I got a few sets of corsair and OCZ D9 that Iv'e played with at high voltage and never a problem. Though only my 8500SLI did I run for a year or more with 2.4v (and only one's benched over 2.5v). But with an EVP of 2.35v, you can get pleanty of speed out of that voltage, so theres little point in breaking your warrenty.
hmmmmm M.Beier, what memory are you running at 2.8v?
on what board?
Crucial Ballistix PC6400 D9DQT 2*1GB and it was on a lot of different boards...
P5B-E+ for longest time, however P5W Deluxe (975, dont remember exact name)
ive noticed mine get fairly warm to the touch at 2.3V-2.4V; ive never tried any voltage over these.Quote:
Manuf usually say 2.1-2.3....
i'm a chicken, value my rams longevity, and use 2.15V:) run around 1066@ 4-5-5. with 6400 hz gskill.
yr asking for dead ram with >2.3-2.4V in my conservative opinion.
You did however see that the topic was on D9GMH, which is a different manufacturing process than D9DQT? The fact alone that D9DQT are a 92ball design, in contrast to D9GMH being a 60 ball design, does make a difference here. So what you are doing is comparing apples and oranges.Quote:

I've been kissing 3.4v on GKX, which to my knowledge is pretty much a like... They survived... However, that wasnt 24/7, but bench session, so I dont tend to agree..
My third set of D9GMH/D9GKX now (because the others i killed when OC'ing), and I can tell that I should not recommend any voltage over 2.2v for 24/7 use. These CMOS chips not dies because of high voltage, but for heat, so if you want to run, let's say 2.3-2.4v, use active cooling and it should be no risk, but I will not guarantee they survive very long when using over 2.2v for 24/7 use.
I always use an 80mm fan blowing some air and it does very well to the RAM's.
Manufacturers like OCZ that say 2.4v for some D9 based mem's guaranteed is not understandable.
Okay, again, one more last time! :)
There was an article here, on XS, like 1.5 year ago...
I STRONGLY SUGGEST all of you to read it, and it will become all clear! Pls.
Micron D9 and Electromigration
And for those, who doesn't have the time or the language skill, here is the point:
Quote:
From what i've concluded so far, for Micron D9 chips 2.4V is the maximum allowable voltage for 24/7 use, considering decent cooling is provided.
:slap:Quote:

This is recommended because? That's common knowledge if you've done some high school physics with two minutes of wikipedia reading and its the same with low temperatures/high voltages for CPUs but no one seems to mention it in that respect. Especially with oc'd 45nm CPUs.Quote:

You ran your memory in a P5W DH Deluxe @2.8v???Quote:

Regardless, the P5W had a horrible time w/ it's memory controller as far as scaling was considered. How fast were you running these sticks@2.8v??
2v on a 45nm CPU?!?!:shocked:
Maybe if your trying to a sucicide run @ 6GHz:up:
1.85v daily......:rofl:
Have you seen the results people are getting at 1.6v?
Check the extreme OCing section:)
i think he been smokin n usin ddr1 @ the time lol
i got way too many dead sticks @ 2.26v with active cooling the sticks never even got warm the most i ever used was 2.34v for a few bench sessions
Well just the other night I had my OCZ over 2.7 for a few hours, theyre as merry as ever, I ran them for a year over 2.4v.
Sure you can probably kill them doing so, but with the price, what's Xtreme about not taking the risk.
It's not like you guarentee to blow them up, i'd say the chances of them getting electromigration under 2.45v are pretty slim, you would have to be unlucky, and live somewhere in the tropics with useless case cooling.
Look man...Quote:

Imho, the guy who wrote that article, knows whats his talking and I trust him, because I am nowhere nere to his knowledge.
Thats it.
Anyway, with decent cooling 2.4V can be still good, we all know D9 based chips response pretty well to voltage increase...
Coolaler used more then 2v on QX9650, just check HWbot.org ;)Quote:

And yeap, it was voltmoded indeed.
I run mine (G.Skill 6400 HZ) at 2.35v but will prolly up it to 2.4v cuz they love it. They're only rated at 2.1v, but that's just because the manufacturer is a wet blanket... :)
As far as I'm concerned if they can't handle 2.4v they deserve to die anyway!

When anyone gives advice to people, not just one person who asked, everyone reads it and most people unaware follow it, it's the net; the responsible thing, unless you're willing to cover the cost of someones product loss if s/he follows your advice, is to just tell them to run stock or sub-stock volts which their RAM MFG will warranty or they just end up doing what you say and for too many that will give them dead RAM for multiple reasons. We know many motherboards overvolt RAM, this may be one reason, user ignorance is another but anything more than stock rated volts and you need to make it fully clear that it can and has killed RAM and you can't guarantee it won't, not because it's not cooled just because your or someone who you knew has RAM that never died at X volts when cooled, but because this is a community and community feedback speaks for itself and this time, we do know that 2.2V rated D9 RAM at 2.2V and above has resulted in corruption regardless of cooling/user experience. My last Crucial D9 pair died at 2.31V (DMM) one-off with 2C ambient and 152CFM Delta fan on it, you see. :(
The new pair I have, has done 3.0V 5-6 times without damage fine (no, no stability testing at plus 2.4V, that's exactly what kills them) but I'm not about to go around and say, "2.7V is perfectly fine, gives no damage if cooled properly" just because mine turned out that way. Every IC is different, just look at CPU/RAM overclocks and you'll see.
Thus, all you can say is: "I run mine or I ran mine 24/7 2.xV and nothing happened" rather than making a universal statement "all D9 can run 2.4V perfectly without corruption if well cooled" because while the first is a user feedback opinion and factual, the latter is a vacuous conjecture which is based on no real evidence and has already been proven false by equally reliable users. :)
As for anyone who wants to throw volts at them, that's their choice, no obligation and they're to blame if they kill them by expecting whatever volts above stock to work.
I agree with KTE ;)
And if you beleive everything you read, then your bound to come unstuck. The internet is full of garbage, and if some one doesn't get the answer they want from here, it will be posted in a thousand other places.
Sure anyone who starts overvolting and overclocking knows JDEC is 400-5-5-5 and 1.8v, and will know anything beyond this is potentially damaging. Why can't people just take resposibility for they're own mistakes, why do we need "to cover the cost of someones product loss if s/he follows your advice".
This is the internet, if you beleive everything you read, your a total idiot. Read, learn and sift through the information like a fine comb, and you will get it right 9/10.
And KTE if your sticks are dying below the manufacturers recommended voltage, you can RMA them anyway, and I think its time to get a new mobo, its obviously not the RAM.
I killed a set of D9's on my RD600 @ 2.3v w/ active cooling 24/7.
Current running 2GBHZ @ 2.2v on a P965-s w/ active cooling 24/7 (6 months no probs).
I recommend running 2.2v 24/7 for D9's
Only one pair of Crucial D9 died on this MB The0men, it's a new MB and the loadline voltage regulation is very good, slightly undervolts though and the rest of the RAM (3 pairs) run fine including 2 ProMOS and 1 Crucial. It was just the old one and it was used on two MBs rather than one. Simply a bad IC, died v.near stock and it was unexpected.
O sorry, I was under the impression you have had multiple set die.
Hmm bad luck really. I have no worries running lots of volts.
I personally think its more to the idividual stick of RAM, some are fine running high voltage all the time, some die below the rated like yours. Sounds more like an imperfect chip rather than the actual voltage used.
Saaya, I have perhaps worlds fastest DDR3 kit ;)Quote:

Crappy motherboards (Gigabyte P965 S3 rev 1) and a Biostar TP35D2-A7. I did do a few bench sessions with the PC8000's running up to 2.81V but never with my PC6400's. Both sets are pretty much dead (3 sticks will run 667mhz 2.1V 5-5-5-15 but any more voltage or any faster = memory errors or no post.)
From what I've seen, the cheap motherboards have been the killers for people running 24/7 with cool temps and lower voltage. The sticks with 8 layer PCB's tend to handle voltage a lot better.
hmmmm one stick died right? or both?Quote:

And if its only one stick, or even two, but has been used on multiple mobos, and died after a year, it definatly wasn't a bad IC, If your running them at stock or lower voltage, they either work or they don't. I don't encourage people to go and flog the crap out of their RAM, but I also don't see the point in trying to scare people off being able to use the reccomended voltage all the way up to 2.5v if it say's to do so. If it blows up, you get warrenty anyway, and I have never had D9 die on me under 2.6 volts, even sets benched over 2.6v.
Conclusion: some people have bad experience with D9, some have good. But on the same token, any other chips can die under the exact same circumstances, and alot of it boils down to the motherboard you use it in, and luck of the draw, I wouldn't say D9 is any more prone to dying than anything else, just we hear more about D9 dying, purely because of the mass quantities people on XS use in comparison to other chips. Not to mention how much more abuse D9 cops, and can honestly take.
My G.Skill 8500 HK's D9GMH are warrantied for 2.3v - 2.4v. When I first got them I ran 4 sticks with no fan at 2.3v , the 1st kit died in a month, the second kit a month later. When I powered down the PC they were almost to hot to touch. So I have only 2 sticks per PC now, 1 cooled by a OCZ cooler, the other by 2x80mm fans while my OCZ are under RMA. I have them 2.36v 4-4-4-12 they seem ok. But I figure the manuf say 2.3 to 2.4v it's ok.
you think manufacturers are right sayin they good for 2.3v-2.4v 24/7 they wrong they will die sooner or laterQuote:

Well, just an update, my FlexXLC has died running only at the volts specified in the EPP profile(slightly undervolt on the board). @:
Kind of disappointing that their own specs caused them to die.
They always stayed cool to the touch, but died anyways.
One stick is 100% dead, other can't even run stock EPP.
Hopefully Tony sees this and helps me out. Never had to RMA any of my many OCZ sets yet.
Maybe D9's just have poor reliability at any voltage?
Did you measure your Vdimm with a multimeter? My Asus X38/DDR2 board overvolts by 0.1V (!)
imho, it's not about D9's being sensitive or not; it's about common logic: the default voltage for all DDR2 is 1.8V. The manufacturers might want to impress customers and overclock their RAM for the consumer.
Meaning that they take perfectly healthy DDR2 ICs, feed them with 33% more voltage than what they're designed to be fed with (which is ***a lot*** anyway you see it), find their safe limits, test them for possibly "days" if not just hours, and eventually sell them as PC-7xxx, 8xxx and 9xxx.
Also, a warranty is not a guarantee that something will run problem-free for the agreed period of time; it's just an insurance that the manufacturer will fix/replace it for you. It might as well fail every 3 months.
And to stay on topic, up-to-2.1V w/o active cooling, or 2.3 with active cooling, for 24*7 use.
I would love to run my 6400 GBHZs (2x1gig) with more voltage than 2.1V.
But my Gigabyte GA-965P-DS3P always reboots after I set +0,4 (2.2V) in BIOS. After I go back in BIOS..PC Health Monitor show 1.8V DDR Voltage "FAIL".
I don't know what to do!
I ran my Gskill PC8000 HZ at 2.1v for a few months. No problemo. Now I use less voltage because I found the damn Ctrl-F trick on my old DS3;)
2.4v is what I personally think is max, but depending on your needs/wallet I guess 2.2v is a good combination of safe voltage and good performance.
your the most realistic member of this forum....;) agree %100 2.2v with fan at good clocks-timings last forever.anything above(2.3v+) that is rma time sooner or later.Quote:

See the thread I just posted on OCZ Flex @ 850 3-2-2. I run them comfortably at 2.7V (set to 2.6V in BIOS) on water. Anything less isn't enough for good overclocks or low latencies. They were sold to me as 6400/800 but CPU-Z and SPD-Z show them to be 9200/1150. Like it says on the tin (well Aluminium and Copper) they are very flexible. Nominal voltage is 2.35+/- 0.05.Quote:

I have had the odd problem with mine when going for high speeds or low latencies (or both) where the board wouldn't post even after clearing the BIOS. Solution was to install some cheap RAM, boot, shutdown, reinstall the Flex, boot, shutdown, remove cheap RAM, boot, tweak until it happens again.Quote:

Nope no watercooling. And yes, they have problems booting, but one stick is 100% dead. no booting.Quote:

At high temperatures resistance goes up leading to higher current, without sufficient cooling the heat stays on the chip so you need more current so you make more heat and need even more, positive feedback until something breaks down. This is why active cooling is important, and also why components that run hot overclock well when cooled well as heat is the limiting factor so shifting it raises the limit.
Also electromigration is much less of an issue in copper interconnect than it was in aluminium, due to the higher atomic weight of copper atoms they are harder for the electrons to push around, I'd go into the equations but it's years since I worked in a fab or on semiconductor research.
You have what sounds like a decent water set up and RAM with built in waterblocks and you didn't get it wet?Quote:

it would affect my cpu temps too much to add all the extra restriction and complication. Plus I like to change mem.Quote:

What are you running that Wolf at? I had one stable at 3.6GHz with no thermal issues (4 hours 3D mark, overnight Prime95) and a mate had one stable at 4.2GHz on air, both were on 780i boards. Unless you are at 70C+ loaded, have a weak pump (<400lph) or an under cooled radiator I doubt you would have any issues besides modifying the loop.Quote:

As for complication two F-splitters and a foot or less of 1/4 inch hose.
When I change memory I'm going to keep the coolers. I think OCZ should sell the coolers separately (hint, hint @ RyderOCZ).
Well just an update people.
I got my ram exchanged in store for a new set.
The new set is running 1200mhz at 5-4-4-18 w/2.2v 100% orthos stable for 9 hours.
One can expect ram to degrade In overclockability after prolonged periods of high voltage use. My previous dims, ocz plat rev.2 did 900-950 cl4 or 1100 cl5 @ 2.3v, I did a lot of suicide runs after than at around 2.6v and they were never the same again, lol. They could hardly do 900cl4 with 2.35volts
Well I look at it this way... This is XS, and it's hardly worth having D9 unless you want 2.3v+ in it daily. If you want low voltage you have qimonda which is probably better around 2.1v mark.
why 2.3v+ i'm running 1200 mhz 24/7 with only 2.12vQuote:

i'll stick with 2.13 lol i dont need to got above 1200mhz
No I haven't yet.Quote:

Do these no longer use D9?
whats your memory brand?maybe ill try my luck finding one like your one :up:Quote:

New update.
Now fully 100% orthos stable at 5-4-3-15 at DDR1200 with only 2.2v.
