Safe Voltages for Venice?

[imported_g33k]

I recently bulit a system for a freind. I overclocked the Venice 3200+ to 2600mhz. I had to increase voltage to 1.67 volts to get prime95 stable. I'm using a Zalman 7700cu and temps seem good at 50C under load and about 30C idle. Considering temps, is 1.67 volts safe for a Venice core?

edit:

Chip specs are LLBLE CBBID 0519

I recommend 1.6 as the max with air cooling, 1.65 with water, 1.7 phase/cascade.

If temps are good, why would it matter what type of cooling you have?

 

[KoolDrew]

Good temps do not make a high vcore safer as many tend to think. There is a limit of what you should push through it. Running a high vcore will shorten the lifespan of your CPU. So just because it is running fine now does not make it safe.

 

[theMan]

it may only last a year or 2 at voltages like that, if you dont upgrade often, reduce it.

Isnt high temps, what actually kills the processor? Higher voltage, spurs higher temps and this leads to a dead processor. But if temps are good...

Anyhow I would like to hear from other Venice owners in regards to safe core voltages for Venice.

Too much voltage will kill a processor no matter what the temperature is.

15% is as much as I'll increase the voltage for long periods of time. I'd rather keep it under 10% above default.

Use Cool n Quiet. Most of the time, the CPU will be running around 1.2-1.3V. The CPU will not see +1.6V unless it is running at full load.

I just tried enabling Cool & Quiet, it didn't lower voltage at all. Besides, I heard that its better disable Cool & Quiet when you are overclocking.

On the advice of the posters so far, I backed down volts to 1.4 X 1.15 = 1.61V. Where I had it at 1.67 Volts is too high for my liking, I may have to back down htt though. I'm retesting Prime95 right now.

I still don't understand why it would be ok to go 1.65V on water, but not on air. A good air cooler such as the Zalman 7700cu and water cooling can be the difference of maybe 5C. But if temps don't matter than why would higher voltage be ok with different cooling?

It should drop the CPU multiplier from 9x to 5x for an AMD 64 3000. You can confirm this with CPU-Z. The CPU temp should also drop. Mine went from about 53C under full load (Prime95 max heat) to 34C.

There is no logical rationale why one cannot use C n Q when overclocking!

Yes, but my concern here is not the CPU multiplier or temps. I am talking about voltages. My temps are fine.

cool & quiet works very well on DFI LanParty UT 250gb , Running 2250mhz here on my 2800+ with cool & quiet enabled.

Make sure you have the latest bios,then the AMD cpu driver,then enable minimal power in power options (control panel),and be sure you have cool & quiet enabled in the bios.

I'm running a Venice 3500+ at 1.7 ( 2684mhz).. I'll let you know if it dies...

LOL!

The thing is, this is not my computer. I'm doing a favor for a freind and building one for him. If it was mine, I would run at a higher voltage.

If lower temps don't make higher vcore safer, why do you recommend higher voltage with better cooling?

Yes, my thoughts exactly. I don't grasp his logic.

1.67 is too high for my taste, but it should still last for a couple of years..

unless you have EXCELLENT case cooling, I find 50C loaded @ 1.67v with only a Zalman 7700
kinda BS.. But you never know..

With an XP-90 @ only 1.49-1.51v I can't even get below 52C..

I have a 92MM Zalman pushing about 50CFM as well..

Keep us posted..

I'm sure it will last for over a year though..

I have a Lian-Li PC60 and it is an excellent case. No BS. I peak at 50C at 1.67 volts according to Smart Guardian on my DFI Ultra-D.

I lowered voltage to 1.61 and I had to drop htt to 255. But my freind will still be very happy and I don't have to worry about his proc crapping out in a year or so.

what real i love you edited mypost? is there any temp/ratio or anything liek that like if you have subzero temps voltage can be higher or something. Can you fry a cpu with voltage,under 2v, or does heat have to do that?

 

[SketchMaster]

I have a rule that I try to stick by. If I'm building a computer for some one other than myself I DO NOT over clock it. Down the road some thing could go wrong, and guess who will have to pay for new parts.

I would lower the clock on it so you can get the Vcore down to a safer level. Yes it won?t be as fast but I bet your friend won?t miss the 200 or so MHz.

 

[imported_g33k]

Sound advice, but I bought all performance parts with the intent on overclocking. And while I admit, I love playing with the hardware, I also don't want to over do it. I'll probably back down to 2.5ghz and drop v core down to 1.5 volts or so. Really, I don't want this to come back and bite me in the @ss.

Wow, those temps are very good then.

289x9=2601 at 1.32V... 100% stable [meaning there is nothing I can do to cause it to crash short of pulling parts out or throwing something on it, like liquid... I ran Prime95 for 4 days straight with no errors or warnings, and I had video encoding going on in the background at the same time... ] OR i can run 317x9-2853 at 1.65V with 80% or so stable... with my VCore at 1.6, I can do 300x9=2700 100% stable... I just dont like to push the CPU that high with voltage because I need 110% stability and for the CPU to last 5 years or more...

Oh well, at least I know that I can count on the CPU with voltages like I run them, at 1.32

Yes, so is higher volts ok? LOL probably not, but then why do people go water cooling if higher voltage is a no-no? I always thought that people went to water cooling in order to get better temps, so that they can raise voltages, so that in turn they can raise htt.
