Farewell to a fallen hero!!! 32M @ DDR2-1242 CAS4 was 6400HZ's last breath... :)

Man, but was that a FIGHT or WHAT :fact:

E6600, stock cooling @ 21C ambient
ASUS P5B Deluxe, vdimm & vmch mods

vdimm: 2.45v (BIOS) --> 2.80v LOAD (DMM)
vcore: 1.51v (BIOS) --> 1.49v LOAD (DMM)
vmch: 1.65v (BIOS) --> 1.67v LOAD (DMM)

G.Skill 6400HZ @ DDR2-1242 5-4-4-4.0, 414x9=3726Mhz -> SPi16M - 5:49.516
CPU-Z Validated!

G.Skill 6400HZ @ DDR2-1234 5-4-4-4.0, 414x9=3704Mhz -> SPi32M - 12:45.203


Earlier today I have done a primary dual 32M run and passed it @ 372x9=3350Mhz, DDR2-1240 5-4-4-4.0 (DDR2-889, 3:5 ratio) but I did not save it as I was expecting to work on a better time :brick: I'm CPU limited for dual32M as it is stable only up to 3.6GHz dual32M. It really cooks it up heavilly on stock cooler... So, all I have left in this department, is a set I did few days ago... :( I had so many other benches planned to do...

vdimm: 2.40v (BIOS) --> 2.75v LOAD (DMM)
vcore: 1.45v (BIOS) --> 1.47v LOAD (DMM)
vmch: 1.65v (BIOS) --> 1.56v LOAD (DMM) - (vmch mod was done after this run)

G.Skill 6400HZ @ DDR2-1224 8-4-4-4.0, 408x8=3264Mhz -> dual SPi32M - 15:20/15:15
28 photos taken every pass during calculation



Unfortunately, RAM is dead now :( It served me very well for the last 4 months, from 2.9v on AM2 to now 2.8v on C2D. This serves also as a precaution to all us XS freaks, be careful with voltage and cherish your RAM, hehe. You never know when it's gone :)

My G.Skill 6400HZ

May 06 - Sep 06

Thanks for dropping by and join me in mourning :D :peace: .... j/k :) Just wanted to show off some kick a$$ clocks :)

Oh man, sorry to see them go :(

I hope you gave them a proper burial! They went out with a bang, that's for sure :D

Wow! G.Skill 6400HZ @ DDR2-1234 5-4-4-4.0, 414x9=3704Mhz -> SPi32M - 12:45.203 - the screen shots will live on! Those sticks did a lot more in their short life than others can even dream of. :D

2.8v kills. Duly noted. Both sticks DOA? No signs of life from one of them?

It's sad story ... so great stick die :(
So what Vmem is "safe" for HZ 2,7V ??
Great scores :D

my condolences

Where can I make a donation for the Gskill HZ memorial fund? :(

Hahaha, sure... My pocket? :lol: j/k

But seriously, I'm just happy that this set flew really high, not really sad that it's dead. Not looking for pity, I was just kidding...:) I mean thanks to such high mem clocks at tight latencies, those 3.7GHz SPi16M & 32M times (I think) seem just stupidly fast! I'm happy, all I can say!

Hehe, you might be right, man! Thanks!

Well, the story is, that one stick is dead but not the other... Quite common symptom, from what I have seen, right? PC doesn't boot with both sticks. When tried separately, it doesn't boot with one of them but it does with the other. That stick is absolutely fine and flying as new! I kind of thought maybe SPD info got messed up, so I dumped one from a good stick and used it to burn the bad stick with. But that did not help... I'm gonna let it rest for some time and see If it boots in my AM2 setup. But I'm not holding my breath :lol:

I don't really know. As low as you possibly can, to achieve what you need :) Thing is, I have not used this set for a month, until two days ago, when I volt-modded my P5B Dx... Since then, I had tested HZ for perhaps 8hrs altogether, with 2.5-2.8v... Once I was trying for a better dual 32M run, PC crashed few passes into it. Then it crashed on a reboot, when loading Windows and one more time next. After, that it did not POST at all...


Anyway, results are awesome so it's all good :up: Now, nothing keeps me from mounting my single stage, at last :lol:

U could try contacting GSKiLL and ask for a wooden box in which my 2GBHZ were sold if u dont have it anymore - would be a nice ceremony :)

no warranty?

iLL

I think it voided the warranty :0

Hello Bachus, I'm sorry to read that.

The same story happened to boblemagnifique (Geil pc6400c3 + P5b) and to me (p5b dlx + crucial pc8000).

For my personal case, the VDimm regulator failed in the boot. I saw 4.2V whereas he was configured in 2.55V (2.15V in bios + 0.4V from mod)

Another time, really sorry for your memory... Expecting DFi with 3V VDimm

Man Bach..now I see what you meant.:( That really sucks about your ram man. So was it more to do with the p5b vdimm regulation going bad?? or the sticks just failing from acumulation of too much vdimm and those long ass grueling 32m runs? I would ratehr bypass all the vdimm reg on this board now for testing, and just use Hipro's Maxi to feed the slots.

can you completely bypass it with hipro-toy :D

Sorry to hear Bachus :( Those were some amazing sticks and these last runs were no exception! Same thing happened to my great redline CH UTTs back in the day, died in the middle of a 3d run then one wouldn't work, other did.

I saw that and I've been worried to vdimm mod my p5b. Bachus do you have anything to say about this? Or did you not check your vdimm constantly?

Sorry to hear that, Bachus.

Anyway, your G.Skill is a true warrior......:)

I really don't know If dumping it all on voltage regulation is the right thing to say... For now, I hold to my little theory (doh!) that long testing at high voltages will contibute significantly to death. I'm only curious, why is it that oinly one stick seems to be dead... With those double-restarts on ASUS, what it does is first it boots at default voltage (1.80v, which after vmod is 2.18v), then it shuts down and boots again with what is set in BIOS (in that case, e.g. 2.45v which after vmod was 2.80v).

perhaps something messed up the SPD?

just wondering, how did u kill it??

RIP Bachus' HZs :(

curious Bachus what type of fan cooling did you have on dimms ? :)

DDR1242, that's just sick. SO it seems that high voltage is not instantly lethal to DDR2 IC's and is more of a long term thing.... you got 4 months out of them, that's terrific. The other day I pulled some of my MUSHKIN REDLINE DDR BH5 stuff out of the closet and worked on a DDR board for a while. After a few months of 3.8-4.0v OC'ing they had lost their OC-ability and one of the sticks was dead.
