After dropping my Opty 165

Well to cut a long story short i was tidying up my PC and removed the 165,then disaster,somehow i managed to drop it onto the floor [laminate] and snapped off 4 pins :mad:

As a replacement ive got a Venice 3000 from OCUK.Whats a safe voltage to give these on air cooling?

 
Kesnel would probably say around 1.7v on good air cooling and I'd go along with that now I've more experience of AMD overclocking. Although to be on the safe side according to AMD the absolute max is around 1.65v for their 90nm CPUs. :)

But yeah, be sure to keep the temps safe at around 60c max as well.
 
1.4v and 2.6ghz its idling at 33c.Warm here though so might wait until it cools down later tonight to see what it can take.
 
Decided I should elaborate a bit more on raising Vcore after thinking about it more. :)

Present time we really should take into consideration AMD's use of 1.5v max (and more recently 1.4v max) and allowing for a 5% voltage fluctuation we have 1.575v max (or when default is 1.4v the max would be 1.47v).

Now consider the unstable Vcore provided by most of the motherboards we use (can easily overvolt by 5%) and the inaccuracy of the cheap sensor chips and the Vcore hypothesis could be to only use the Vcore suggested by AMD. However, if we go with that then we have to conclude that current AMD 64 CPUs have hit their limits meaning AMD has very little margin for error when it comes to max CPU speed and max Vcore especially if they want their CPUs to survive a good while. That isn't so far fetched is it?

Saying that I'm now running my very cheap Sempron 64 2800+ at 1.65v and the motherboard reports ~0.03v higher on load so using the new hypothesis my CPU will probably have a very short life span but really I don't care as it's a real budget setup and it's fun having it overclocked to the max (would be boring to run it at 2400 MHz which is it's max at default Vcore).

So I guess for anyone who does care about the life cycle of their CPU then perhaps stock Vcore is the best option and in time we'll find that was a good hypothesis because CPUs will be dying due to running above stock Vcore. ;)

But yeah, I'd still go for high Vcore on a Venice 3000+. It's a highly overclockable relatively cheap CPU and with a decent Vcore bump it'll run very fast and probably won't have to last much longer than around 6 months? :D

Anyone care to back up or rip apart my hypothesis? :D
 
Thanks for that well thought out post mate.TBH the CPU has to laast me about 2 weeks until the Insurance stump up for a new CPU.

Problem is they use "A Certain company that is known WORLDwide" shall we say!Chances of them having a Opteron 165 is Slim at best.

I wouldnt go above 1.6v on air. Is your opty fixable you think? paperclips and sellotape maybe?

LOL no mate its dead as a dodo! 4 pins gone completly and there are about 15 bent at 90 degrees.

Time to order a new one and demand an RMA when they send you a CPU with broken and bent pins... ;)








:o
 
the chip could be repaired, i deal with surface mount soldering and have often repaired pins on intel chips by soldering them back into place, course its fragile but it can be done :)
 
1.6v on air will be fine, depends what your motherboard is really giving the cpu, I know mine overvolts by 0.1v others may do the same, multimeter is more accurate than the mobo sensors

Yeh my mate is a supervisor at Meridian[Boothroyd Stewart] he said it can be fixed using there flow solder machine.But Insurance are going to pay for it.It's just they use that "well known PC Planet"place.

Well i upped the volts to 1.450 and hit 2.7ghz but i crashed out.RAM was probably scaling to high at the timings it was on.
 
1 thing ive noticed,2.6ghz on a Venice compared to 2.6ghz on my Opty the framerate difference is HHHHHuge.Im putting that down to the extra cache on the Opty.

If you get it fixed and it works, I'll have it off you :D
