Micron D9 and high voltage, electromigration effects

[Shiranui Gen-An]

I think both of my Ballistix kits are suffering from this phenomenon as they will no longer boot with default voltages

[unex|st]

Hi all, I had the same problem on a Transcend Axeram 1200 stick. I had it running about five months at 2,15v (2,150v dmm measured) 540MHz 5-5-5-15 on a P5B dlx. Some days ago I noticed it wasn't able to boot at voltages below 2,30v anymore. In less than 48 hours even 2,45 didn't work.

The other one seems to be still ok, I think I'll go for a set of TWIN2X4096-8500C5DF.

i honestly beleive its the boards killing d9
bad voltage regulators
i only lost d9 with gigabyte boards all mushkin xp2-8500
even my kingston value d9gmh are rockin after 18 months but not on a gigabyte board lol

[saaya]

i dont think its just the boards... id say its a combination of mfg problems at micron, bad vdimm regulation, and too high drive strength (680/780/975x)

In the past two days I've had a Geil 9280 kit and a Dominator 800 C4 Rev1.2 die on me
Prior to that, I had a Dominator 8500 Rev 1.2 kit die earlier this year that I never ran over stock settings, and last year I had a Ballistix Tracer 5300 kit to give up the ghost. My P5B Deluxe and P5K-E/WiFi seem to eat D9 for dinner.

[saaya]

hmmm thats odd... what psu are you using?

[Shiranui Gen-An]

Antec Quattro 850W in my main PC with the P5K-E/Wifi, and Silverstone Strider 600W in my secondary PC with the P5B Deluxe. I've already requested RMAs for both kits and ordered a CellShock 1066 2GB kit as a replacement for the non-Micron Dominators I'm sure I'll receive from Corsair.

does anyone know if D9NLH are sensitive to electromigration?

Thats strange, i got my memory secondhand, the person (a great bencher) ran them a few times with 2.6V. i only run at max 2.48, and they still perform. and run at stock. they are insane though, can do 1200 4-4-3-3 : 1180 4-4-2-2-1 . screenies to prove it

Ive been running only on Asus x38 and x48, i think their stability is keeping the mem as lively as possible. im with zsams

What ram is that mate?

[Vivi]

only one brand i know of that can achieve this
team xtreem pc6400 4-4-4-10

pffff :P
running the memory at 2.6v a few times probably wouldnt even damage the weakest d9gmh and d9gkx chips :P just run those sticks at those timings and voltage 24/7 and im sure they will degrade after some weeks to months... but maybe your lucky and they wont...

since ddr2 is fading away and prices are incredibly low, i actually would do it and wouldnt worry about the mem dying at this point in time its not really that big a deal to replace the memory if it dies hehe

[andressergio]

I also can't longer boot at default voltaje with my old ballistix 1066 2gb kit tough never been more than 2,2 stock volts...

pffff :P

yup i not worried lol but i got a nice reseve of d9

2 sets of ballistix 8500 1200+ 2.03v
1 set of ballistix 6400 d9gmh
1 set of tracers 6400
2 sets of hyperx d9gkx
2 sets of kingston value d9gmh
always gettin more am i paranoid

Micutzu, thanks for the informative lesson. Here's a quick English lesson for you in return:

In your post you continually use the word trough. A trough (pronounced "troff") is a container for animal feed. I think the word you are looking for is through (pronounced threw / thru).

Cheers!

no need to crap in this thread dee

[Dee]

LOL. Sorry! Not crapping, I was just saying thanks for the interesting info and helping him speak better English, which, without wishing to come across as patronizing, is very good already.

use just firefox with enabled spell checking and worrying about bad spelling you will not anymore grammer though might fail you

I still can't figure out how a kit of Dominator C4 with D9GMH would die from one benchmarking attempt@DDR2-1200. I think the voltage was at 2.3 or so. They had been setting in the packaging for a week or so unused prior!

yep, those are insane good clockers and love the volts, they even scale with more than 3V.
mine, dual and single channel, why single? fried the other stick at 3,1V. (yes, I realize it was silly to pump 3V+ through d9gmh, but hey, if they are so cheap you can buy a bunch and do your own binning...)

pffff :P
running the memory at 2.6v a few times probably wouldnt even damage the weakest d9gmh and d9gkx chips :P

I remember when certain companies where giving warranty on d9 up to 2,5V (geil, I'm looking at you).

True 2,6V is safe, I'd even say 2,9V is safe, but only for benching.

i've had some ram go bad in 15 min lol so... poor quality control

hmmm brand new? maybe it was overvolted and damaged before... its also possible it got an ESD discharge whih damaged it and when you used it it degraded more and then died...

with what voltage?

[Shiranui Gen-An]

It was a new kit, but I had installed it before and didn't have any issues out with it. I put them back in the package for a while as I was testing other kits with D9. I'm not sure if they got damaged with some of the previous benching runs or not. Perhaps it was as you said an ESD discharge.

[zsamz_]

with what voltage?

2.24v

[Vivi]

saayaa can you tell me quick.

when i want to do suicide runs, like 2.65 V to achieve 700 mhz for FSB testing or something.
how do memory die?
do they instantly die due to high voltage just cause they dont like it
or do they die of the Heat made by 2.6v
