2.5V is right on the border of being safe...run more and you will kill your dimms in under a week.
I have seen quite a few quoting they killed DDR2 while benching now, remember you juice it up you take the risk.

why are some manufacturers releasing RAM with 2.4v rated timings.........are they looking for trouble like those old UTT sticks we all killed at some point
can you tell us more about electronic migration you mentioned in the other thread
i must have looks somewhere else but i haven't seen all that money dead ram sticks reported in DDR2....certainly not even close to UTT deaths we had early this and all last year
once I tested my 8000UL @ 3.15V w/no fan ...
result - mem is alive :woot: but OC @ low volts dropped :(
UTT dejavu:)
So does that mean that 2.4V with active cooling still isn't really safe for 24/7 usage?

Just a extreme Off topic:
I got my DDr2 @ 4.1v... they burned... literally. The side sticker was totally burned. Was matter of mobo :S
:rolleyes: cant imagine burning up a 500$ ram :slapass:
Got pics ?Quote:

always thought 2.5v was safe as 2.4v is being used by many manufacturers so adding .1v wouldn't be much. It's what I was planning on running my mem at.
fhpchris also said that he runs his ram at 2.65v his fatbodies. Think he's been using them for more than a week...
Fatbody is different story i think..Quote:

The lower the produced nm is, the less volts it can take... Especially for longer times.
:D well I should be getting 4 sticks of 5400UL sometime soon so it's nice to know that I can run them at higher voltsQuote:

I ran my fatties at 2.67 for a couple of days, and never used them below 2.58v, but I threw them in Yonah and the aopen board only goes to 2.15v...
heh we all get lazy sometimes.Quote:

Above 2.5V (extended use) and your ddr2 ram will degraded overtime, it Will needs more and more V just to run stable.
The better way imo, is to run 400ish and oc'd your cpu to the max...Unlinked preferably;)
Fatty D9 dies just as fast....voltage shows no mercy ;)
Infact its not the voltage that kills it, you need the increase in voltage to get the memory switching faster, but a by product is more heat and an increase in current used. The increase in current is what kills it as its quite easy to control the heat.
Micron is mad expensive again at this time, if you want to keep it working reduce the vdimm ;)
I have found that the modules will sometimes overheat and stop working with high VDimm. People often assume the RAM is dead. In some cases, but not all, taking the modules out of the board and letting them cool off will solve the problem.
by testing my Kingston PC 4200 between 3.3v and 3.6v during approximately 5 hours, I saw well that 4 chips D9DCD were affected by the voltages, the ram functions but it is necessary for more volts to him so that it starts correctly (2.6 / 2.7v instead of 1.8v of origin) :cool:
I would not test with the other kits out of PC 8500 which I currently have, I dont want of to damage even more the chips in D9GKX which are absolutely not the same price as D9DCD :rolleyes:

I've some DCD also, running at the moment 2.6v for 24/7 although I did run them for about 5 days at 2.9v (lazy me). Not noticed any degredation yet. One thing I did notice was that at 2.9v the dimms were barely warm to the touch with no fan, whereas my GKX got fairly toasty at just 2.45v
Incidentally, my GKX died after only about 2 hours benching at 3.15v :(
EDIT: To be fair, my 24/7 voltage on those was pretty high...
For my 24/7 system I keep the ram under 2.2v.
Only for benching in a controlled AC environment will I bring the voltages up over 2.5v and that is for a short period of time and that is on my bench memory only.
I use seperate semi expendable bench ram when pushing voltages. I recently killed a good set of DDR2 6400C3 on the xbx2, one module still works.
That is why we love the Hipro 5 maximizer :D
We can lower voltage from 2.7 - 2.5 and still get same results :D
