Another Micron D9 dead.

[fireice2]

This is my second set of Micron D9 GMH DDR2-1066 that got flaky even with below rated voltage settings for 24/7 use.

In my first set, one really died after over a month of running @ DDR2-1000 CL4.0-4-4-12 with only 2.2v and with active cooling..

The second set which I'm still able to use @ DDR2-667 used ran @ DDR2-1100 CL5.0-5-5-15 with only 2.0v for almost a month until yesterday... now one of the sticks is dying..

Is my motherboard killing my RAM or am I just so unlucky that the replacement for my first set is a dud as well?

[nzbleach]

my DFI 965 dark has killed 2 sets of d9GMH. I think its more to do with ripple current from the PSU rather than the board. D9 seems to die even when under rated voltage.

Are you sure it was only 2.0v?
D9's don't die until 2.6v

[fireice2]

Yup, it was at 2.0v.... I made sure that I would run the RAM with the least voltage possible the desired speed to ensure longevity.... for one month that is..




Does this mean that the HX620 may have an issue with this mobo?

[NickS]

It's D9 guys.. D9 dies. Not the mobo, not the PSU. It's the RAM

[fireice2]

@nicks

How often do D9's die these days? Having to RMA the RAM every other month is really a pain in the ...

I can't have these RAM replaced very soon since my local vendor is out for a couple of weeks..

[NickS]

Every 3-6 months or so I'd say. Sometimes sooner. I've had D9 since AM2 and I've had 5 sets of D9 total, from 2 companies.

[zodden]

One 1GB stick from OCZ D9 died yesterday. 2.2V since mid April

Microns are not reliable anymore are they? Any suggestions? How bout promos based ram?

Micron is the only good IC's for overclocking...

I have no idea what's been going on over at Micron...is their quality control gone to hell? I oughtta drive 6 hours to Boise and slap them all in the face!

[NickS]

Promos will do 500MHz 4-4-4-12 easy but thats about it. For under 500MHz they rock.

i'll disagree there. i place the blame 100% squarely on the motherboard or user error: see sig

Mine can do 980 rock stable 2.15v 4-4-3-4-3-35-3-3-3-3
And 1140-1160 with 5-4-4-10-4-35 @ 2.2v
PL6

Nope i also have 2 kits dead with 2.10- 2.15 V with very good active cooling and 1200W very, very stable PSU, so i give it to Micron too

[andre X_X]

i have couple sticks of D9 GMH, already over a year and they still perform great. very rare running 1.8 - 1.9v, always 2.0v - 2.6v since i use it for benching. at least my D9 dont die. btw, its Team Xtreem PC5300 C3

[NickS]

Yeah, OK. Wishful thinking.

1. Every set of D9 I've had has had some sort of active cooling, either an 80MM fan, OCZ XTC cooler or a 120mm fan.
2. Most I've ever ran was 2.3v 24/7 BIOS.
3. My Dad's Tracer 1000's died after 5 and a half months @ 845MHz, 4-4-4-12, 2.1v. Explain that?
4. 680i is known to damage ram, but other than that, it's the IC's themselves.

I remember ryuji and I were talking about it. It has something to do with the really old spec D9 is based on and how they won't die on 925x chipsets and something else. I'll have to ask him.

Then explain how I've lost ram at stock speeds/volts with no heat spreaders and a fan over them. I've lost 7 sets of ram, 3 of which never saw over stock anything. Had 4 different mobos and 2 PSUs. ALWAYS had a fan over them. Oddly enough, the set I abused big time with 20-30 hours of 2.8v benching lasted the longest by far. Go figure.

that they dont like low voltage???
cheers

[ozzimark]

but other than that, it's the IC's themselves.

they're very sensitive to current. for reference, the only ddr2 i've killed so far have been intentional, trying to see where the limit was. just keep the drive strength low, and you'll be fine, seriously. if you don't have an option for it, it's certain that the default is pretty damn high

haha, ok, not 100%, there are some bad kits out there, or you just fail j/k

my point is that the micron revD chips are NOT as fragile as everyone makes them out to be. it's possible to run a lot of voltage through them long term without problems, you just need a board that allows enough control over the voltage and drive strength to pull it off. imo at least

Hate to say it but this is why I bought promos.
G.skill HK series pc2-6400, 485mhz @ 4/4/4/8 2.15vcore.

Weird. I'm pretty sure my BIOSTAR board has drive strength options, but I don't feel like screwing with those right now.. especially since drive strength is something I've never played with and from what you said it sounds like you can damage D9 with it.

+1. I have a spare 2GB set of HK's sitting around to use when the Micron kicks the bucket, they rock.

My RAM have active cooling 24/7.

complete settings in the BIOS are

Have a promos base RAM before and I never had these kinds of problems, except for the difficulties in OC beyond 500Mhz. I switched to D9's for better overclocking options and thinking they will last me really long.

tweaking drives gets me more mhz than any sub-timing ever has. i highly recommend you look into it. there are a bunch on AM2 as well

you should, you can get higher oc's sometimes

[bobbobson]

I had a stick die on me. 2GBHZ GSkills running at 2.3 @ 500 4-4-4-12 for a few months. So i was forced to use 1 stick. Im REALLY lazy and didnt end up taking it back for a few months. Just before i was ready to jump in the car i gave it 1 last try (After HOURS of testing the first time) and it worked!!. Kinda freaky. Maby give it a little rest (frezza ?) and try it again. Or maby i got some kind of borg Rams that abzorbed my other stick and fixed themselfs

[learners permit]

I agree with Ozzi on this one. My ICFX 3200 has default ram drive strength of 5 but my D9 prefers drive strength 3 to work the best. Level 5 was causing CTD while gaming and overall instability even when actively cooled. This D9 is reminiscent of TCCD. Low drive and moderate voltage seem to work the best for me and no dead ram yet.
