Last night I BSOD'd and set back to 2.5ghz figuring CPU was having an overheating fit again. Then 2.5 started BSODing so I shut down, threw a fan over the rams, and all was ok for an hour until I went to bed. Came home to the dreaded reboot loop and now even 400mhz wouldn't boot (was running 500mhz before) with stock CPU. Swapped the ram into the black slots on my C51XEM2AA and put voltage at 2.325v and it was stable for about 2 hours of gaming before BSODing. Running 2.35v now.
Unless my CPUs IMC or my foxconn board just crapped out randomly, I'm pretty sure running high voltages for any period of time will degrade d9 eventually :(
Those of you who have their RAM "failing" like this, suddenly running only low clocks - put it on a shelf for a couple weeks.
I had components recover from this condition. Most notably, after that Athene 850W PSU fiasco my magic CABNE had lost 200 MHz overclock. When I wanted to throw it out some time later I re-tested and all was fine, strong as before.
Tony,
Just wondering how effective some active cooling like those twin 60mm fan OCZ XTC's would be for lowering 24/7 temps.
For example if I had memory I normally ran 2.2 24/7 would those coolers let me go 2.3 or 2.4 with the same longevity?
Its not temperature that kills them. It's electron migration.
Still, nobody has answered the major question people have here.
How far can you go 24/7 with an active cooling system on it? Be it a 60MM fan, Corsair Dominator airflow system, water cooling etc.
Personally I've been running 2.4 for a while on my Crucial 10th Anniversary with the Corsair airflow system and no problems.
So Hipro provides added stability w/o even racking up the voltage?Quote:

Hi everyone :)
IS THIS POSSIBLE to run D9 GMH (Ballistix) 3,75v for benching up to 4,0v (for few hours)? We have in Poland one "pistol" who claims that it he is running that voltage on vmoded Biostar Tforce 965PT (but he didn't notice any boost of MHz/timings). He claims that on 4,0v computer don't boot...
We are waiting for pictures :D
I think for 100% that its FAKE
3.75V? :eek: Fried memory anyone? :p: they will be crip and long deadQuote:

I wouldn't be surprised if they just died on boot up at that voltage.
Search function would remove your surprise.
There are people running there ddr2 @ 3.5-3.8V for short benches...not every ram dies immidiately.... ;)Quote:

On stock Vdimm circuit, it is a much weaker design, made to run ok at stock but not at higher volts. So when the dimms get under load the voltage drops, meaning you have to raise the voltage even more to compensate. This voltage fluctuation isnt very good for your ram either IMO.
Is 2.55v too much for Corsair 8000ULs @ 400mhz & 3-2-2-4-6 - benchmark stable ?
Just ran some benchies at this level with active cooling on the sticks and all seems fine, but I don't want to be standing too much on the "edge" here...
Will post screenies very soon.
maybe seconds...Quote:

probably only BH5 can survive those volts.
2.55 should be fine for benching.
i would not run 24/7 over 2.5 though.

to xp boot screen.
:shrug: I've been running Team Group PC2 5300 for 5 months now 24/7 at 2.4v. Only around 373MHz, but higher voltages make me feel warm inside. And speeds haven't degraded a bit, I can bring them right up 100MHz higher with 2.65v. I think the key is good airflow. Especially when benching, people tend to forget. I know I did. I was very surprised by how hot my ram got even after a few minutes of use with no fan at 2.4v. After its first hour or so, my ram has always had a fan directly above it, regardless.
From reading this thread ive decided ill be running 2.3v-2.4v 24/7 use and benching at around 2.6v. This will be on Gskill HZ. This is a safe voltage from what i have gathered, :)

G.Skill HZ 6400 (SN 605)
It is possible on 3,75V but only 5 Minutes :D
Now memory soils taste :(
I keep my GSkill for everyday use at 2.25v but for benching I will go 2.55. I was going to go crank them up to 3.7 for some benching but after reading this thread I decided that my memory costs too much to kill just to lower my SuperPi32 numbers.
Yeah obviously there was some accelerated degradation as Tony puts it.Quote:

I would think the cooling effect would be similar to the effect it has on CPUs. Maybe not completely eliminating extra wear but still effective.
P.S. I like those new Thermalright HR-07 Ram sinks.
Is this the DDR2 Maximizer that will allow you to run lower voltages through the memory?
Someone said he went from 2.2v to 1.85V with same settings. Only difference was the maximizer. If that is true, this is a worthwhile investment.
I have Crucial DDR2-1000 that I am running at DDR2-800 3-3-3-6 @ 2.2V on my P5W (P5W won't do much higher than DDR2-950). The stocks volts are 2.2V. I intend to get the memory up to about 500Mhz with my P5B and try to run it at 4-4-4-8. I will clearly need to run more than stock volts to do this. But with that DDR2 maximizer allow me to do this at lower voltages?
