Am I gonna kill my venice?

[AMD-me]

Well i got my venice prime stable at 2808mhz. One problem it needs alot of volts, 1.7v. I'm running this on a DFI, with a TT Big Tsnami cooling it. My max temp with small FPUs is 54C, idle at 36C. Am I gonna kill this cpu?

Also any idea to how many watts this thing is?

Thanks

Don't think you will kill it, any time soon atleast. The load temp seems in the high range. You might want to find better cooling.

Well i dunno, but pumping 1.7v is alot for a 90nm chip, this is prolly a huge wattage

1.7 seem dangerous, I would only use that voltage with watercooling.

Gah, yea when i turn it back down to 2700mhz 1.475v i never exceed 40C load. I think ill use my 2800mhz for benching

Ive been tryign to take down top ten x700pro heh

Not sooner than at least 5 years from now (and by that time you'll have another cpu ) if your temps are within amd specified range. I had my winchester running at 1.7V for 6 months without problems. Just watch your temps.

[mesyn191]

1.7v is really high for a 90nm chip, best to turn it down for 24/7 use unless you plan to go the phase change route.

[Der_KHAN]

i say as long as the temps are low voltage doesnt matter.

but 54°C is pretty high, so either work on ur cooling or remove the IHS.

[ReelMonza]

supplying high voltage can also kill a CPU on the long run

[mesyn191]

OOoo, removing the IHS and trying to mount a large HSF like the Typhoon on it are a recipe for disaster...

I only know of one person who has done that and thier temps didn't really get all that much better anyways, doesn't seem worth the risk IMO.

How do you guys know if 1.7v is deadly for 90nm Winchester/Venice? I've never run my Winchester @ below 1.7v, even on air. That 54C in SmallFFT is OK, so I would keep it If you can get better temps by changing cooler, than do it. If not, keep it as it is.

Honestly, with good air cooling it could be pretty difficult to kill that CPU at voltage you mention. You just don't hear a lot about folks killing their CPUs, do you? Unless you do sth silly and help it die

"Excessive supply voltages overstress the transistors and can lead to damage due to charge injection from the hot electron effect or damage to the ultra thin gate oxide dielectric from excessive electric field strength. Even if the stress is insufficient to lead to an immediate catastrophic failure, the accumulation of low levels of damage can lead to a drastically shortened device lifetime."

Its a ooold article but all the info. is still dead on.

Gradual Death Syndrome. But then it only happens to .13u cpus like Pentium 4's. But then again even at 1.65v watercooled, .13u chips will die slowly

@mesyn191

eeehhhhhh I stopped reading those 1.5yrs ago, when I gave 2.2v to my AXP-M 2500 and had it 24/7 @ 2.1vcore. Everybody around was saying that > 1.85v on air = DEAD!!! I still have that CPU, in my everyday/work NF2 @ 2690Mhz / 2.1vcore

Of course, it's all truth. It will die one day, but question is WHEN!

[mesyn191]

If managed to get 2.2v on your AXPM then you don't know how lucky you are...

I went through 3 AXPs and 2 AXPMs and not one of them was stable above 1.85v with good water cooling (Swiftech Quiet Power case modded with a Eheim pump and bigger 2x120mm fan rad) and I couldn't get either of them over 2.4Ghz stable...

2v killed 1 of the AXP 2500+ BTW too on air cooling, and many other people could hardly run theirs stable @ 1.8v due to heat....

I think your experience isn't common and shouldn't be viewed as the normal way to go about OC'ing.

well, if they can't do 1.8v stable due to cooling, they need better cooling. all of this is irrelevant if the temps are too high, as temps definately kill

[mesyn191]

Only 1 chip had poor cooling though, all the rest had watercooling. They didn't die but most of the time I could hardly even get them to boot, temps never got over 10C above ambient with that WC rig too BTW...

[bachus_anonym]

@mesyn191

I don't know about that being my isolated experience. I used to run a folding/docking farm made of 5 NF2/AXPM setups. ALL of them run 100% LOAD, ~2.55-2.6GHz 1.95v 24/7 day and night for about 6 months. I only have one of those AXPMs left, best I had, that I use now. It's rock-solid @ 2.1v/2.69Ghz with SP-97/92mm quiet fan. Mobo on the desk/temps LOAD up to 53C.

Anyway... We're getting waaaay to far away from topic...

To summarize... I would not hesistate to keep Venice @ 1.7v with good air-cooling for 24/7 operation

[mesyn191]

bachus:

Like I said I think you're damn damn lucky then. FYI I've only _ever_ had one good overclocker, a AXP 1700+ that did 2.2Ghz on air. Even with phase change my OC's suck ass (currently have a A64 3500+ @ 2.74Ghz @ -12C (core temp) with my VapoLS)...

[WeStSiDePLaYa]

ive never had a chip die on me. ive pumped 2.0v's through axp 24/7 on air. and pumped like 2.1v through an old a64 for a while and no deaths.

Exactly. Pretty sure excessive voltage can damage the junctions in a transistor, regardless of temps.

[koei]

There would be wear and tear no matter what voltage. Nobody really knows how long it will take and it's not exactly against common sense that 1.7v is not as safe as 1.4v but then again, I doubt the chip will die on you due to wear before you get your next chip.

Well, I've a TBred 2400+ that has been running for more than 1 year at 2'1V 24/7 watercooled, still ocing like a mad.
