opteron165 overclock opinion///

[svsnow]

just wondering what you guys would do ...
i have an si-120 w/ 120mm fan

i can either go with 2.6ghz 1.35V
or 2.7ghz 1.4V'
or my latest overclock that i just primed
2.8ghz 1.45V

Also i plan on keeping my system for at least 2 years...
should i put it on 2.7 @ 1.4V ? because its more concervative and wont strain its lifetime,
or go with 2.8 because its able to do it on a low voltage? 1.45V
i would imagine 1.45V would be fine... but it gets to about 54C
and 2.7 gets about 52C max.....
i belive my sensors could be off as others with my same setup are getting way lower temps... also i have good case cooling and decent room temps .. as well as a NV5 silencer (which helps a bit)

 

[Bobthelost]

Hmm, i'd go with the 1.45V myself, it will hurt the lifespan, but since it's rated for 10 years i think you can bear to lose one or two (or even half).

Those temps are high though...

 

[atybimf]

I agree with Bob.

 

[svsnow]

well my mobo sensors i think are of a bit.....
as it would say my 3000+ venice w/ venus 12 would hit 50's...on only 1.5v and even in the 1.4voltage area i think it would hit 50's easy

also isnt it designed to handle liek 65C max also though?
so theoretically the temps should not be hurting the cpu at all . jus tthe slight voltage increase.
it usually hangs at 51-52 sometimes 53 during a dual p95 (this is on 1.45 V)
and the 1.375voltage is onyl a few degreese more ....the only difference is with lower voltage i can have the fan quite a bit lower as to this voltage it needs to be at least 1/2 way load to be able to keep temps <54 C

 

[svsnow]

i mean 1.375 is only a couple degreese LESS liek 51 -52 MAX with fan on fuLL

 

[AMDxx165xxfx60]

do you know the stepping by any a chance?

 

[MDE]

1.45V is fine, I'd try going past 2.8 with that CPU.

What will you be using the computer for?

encoding/gaming/editing/ETC is on 24/7

 

[svsnow]

id say most of the time is gaming....

 

[svsnow]

i didnt write down the steeping on the cpu when i put it in so i dont feel liek takign off the HSf to check ..any software where i can get it ?
CPUZ just says 2 liek them all.

 

[robertk2012]

ok for gaming you wont see much improvement in framerate from 2.3/2.4 on up. Encoding applications scale well though. If it was me I would run it at 2.6 with the lower voltage and cooler temps.

 

[F1shF4t]

yea i would not really want to go above 1.4 v on a dual core even if the temps are fine, the difference after 2.4ghz is not much at all, also most mainboards dont have thermal sensors where voltage regulators are, the dfi ultra d has em and they do get quite toasty when u use high voltage + hight clock speed.

 

[l Xes l]

i say 3ghz at 1.6v

you go first and then i'll follow!

And also theres about a ~2 sec super pi 1M time difference from 2.4-2.8

from 2.7 to 2.8 i dont even really notice it. But at the voltage required from 2.65 -> 2.8 has a difference of .03V. To me .03V extra is worth the .15ghz increase

I like that also

 

[svsnow]

i think im going to stick with 2.8 ghz....i can run my fan on lowest and it wont fail ...but i keep it on med speed
right now im trying to get 2.8 @ 1.43V

Thats a nice OC for that board! I traded my UT ultra-D for an Expert and have been amazed at the difference.

I can do 2.85 at 1.50 volt but can't get 2.9 stable even at 1.65v. And heat aint it if I can trust my sensors at all. My max load never gets near 50 C with 2 instances of P95 LFFTs and looping 3DMark.

Each bump in OC MHz is purchased at a a geometric increase in voltage. I don't think you'll get 3.0 but you might get 2.9, but is 100MHz worth the voltage? Not past 1.5 to 1.55 i isn't. Well actually after 2GHz 100MHz is really not noticeable IMO. Except in benchmarks.

I say 1.55 and below is plenty safe with top end cooling and a good board like you have. Past that is getting a bit risky for 24/7 use. Like eveyone says how important is the PC to you in terms of downtime? If it went down could you deal with it quickly or are you too busy? Can you deal with any downtime at all. Do you have a backup chip? You'r thinking 2 years so if its OEM you'll be out of warranty, but if its retail boxed, then at least you won't lose the investment, but Its still not a bad idea to have an extra chip lying around.

I got a cheap Opty 144 in trade before they became "Hot" as my backup.

Good luck, and I think your fine either way you go. 2.6 or 2.8 on a stock 1.8 chip is a crazy good problem to have. and its DC!!!

Can you believe that?

So why did you ask for input? Almost everyone said 2.6 except for the ones that want you to fry your processor and try and hit 3.0. Ill keep this in mind next time you have a question.

Good Luck

Please do not tell people you can use 1.55 volts safely. Thats not to bright.

If you overclock you have no warranty.

 

[svsnow]

i use 1.5-1.55v on single cores safely , but i have little experience with dual cores ....
my max i will go as for voltage on my dual core is 1.45V ( i consider pretty safe) and in 2 years when i dont need it anymore ...depending on technology .. ill prob take it to 1.55V when its not too big of a deal to have to pop in a new cpu

 

[svsnow]

because if i use 2.6 .. i realized my ram will be just a little too unstable even with a lower multi .. it will either be way to high or just a lil too high for 100% stability and i i use an even lower multi it is just being ran slower than i would like
2.7 i have to use roughly the same voltage... and i get the same temps ...i did alot of testing. and 2.8 just seems to be the best

Im confused? Please explain?

 

[svsnow]

why are u so negative... i didnt ignore your advise.. although more people voted for 2.8ghz+ . only u and 1 other voted for 2.6.
seriously though i would go for 2.6 most likely but right now im having some strange problmes getting my ram to run the ddr540 it needs on that setting.. the next lower divider would make my ram run slower than i prefer...
although im doing some testing right now on 2.6 ..if the ram is stable i will probabally stick with this .then in a year or so i will bump to 2.8 when i can offord a cpu (in case it burns out in a year from then) * which i highly doubt but you know..
overall thanks for the advise.. and i guess since theres not much improvement in gaming with my 7800gt from 2.6-2.8 ... 2.6 sounds ideal .. hey a fx60 basically
