Hey, just a quick question... well two really.

1 - Is is possible to limit my 965 to just use two cores?

2 - if so, would i see and overclocking boosts/performance benefits?

Thanks.
 
Someone told be i'd probably get a better overclock from my CPU if i could limit the amount of cores it used from 4 to 2. I seem to have hit a wall at 3.8Ghz no matter what i try.
 
to be honest, most processor intensive applications will have much more benefit from the extra cores, rather than a small overclock.

from what ive read around here the AMD processors, specifically the one you are talking about, doesnt overclock very well.


what are you actually doing with your PC, because the processor might not even be the bottleneck
 
Yep! Had this setup for a good while now, never felt like I needed more power, and I'm a pretty high end user.

3.8GHz is about as good as you'll ever get, unless you have a particularly good chip. I can't get mine stable past that either on the CIIIF. I think games are now multithreaded enough to take advantage of a quad over dual (depending on what you play), so having those two extra cores is probably a lot better than another 200MHz clock speed.
 
I have had my 965 for over a year and re-attempt every now and then to get it past 3.8Ghz. However that really is the spot for this chip. To get 4.0Ghz you have to give it stupid volts which result in temps that you cant run 24/7. What is your NorthBridge at? Try OC'ing it further for extra performance.
 
I thought that the BE editions are meant to clock like beasts? Phenom II X4 945 here, no unlocked multipliers and i've got it from 3.0Ghz stock to 3.80Ghz. Seems that all these are stuck on 3.8 no matter what edition it is.

i think the 945, 955 and 965 are all exactly the same processor, just clocked differently as standard

its certainly the case for the 955, but not sure for the 945

Not true at all. They are split up using a binning process. They test the chips, the highest stable clocking are released as 965BE, the next highest as 955BE, then the next as 945. Any with one defective core are split a similar way and released as the tri cores, and the dual cores the same.

They are created with the same process and are identical in architecture, but none are identical in reality.

As far as I know. :P
 
most have a wall about 3.8 then you have to pump the volts through them.

if your happy to do that for every day use then sweet . i wasnt and stick to 3.7 24/7 at 1.4v

mine does 3.9 stable benched upto 4.1 ghz but the voltage is a bit silly for basically not much difference. theres not many who have 4ghz 24/7 on here with amdX 4 on here. maybe 4 or 5 max and i bet they still lower it :)
 
I have the same problem my pc will bsod (or crash in game) at round 3.8/85 on 1.48v. I don’t like taking it higher as temps go 60+ on load. Now at 3.7 x18.5, 1.47v, 32c idol... would love to hit a stable 3.9+

I've been running a 955 at 4ghz for 6 months now folding@home for 6 months now. 1.425v prime stable but needs to be bumped upto 1.45v to fold some more demanding work units

you done twenty runs on ibt or played bfbc2 with it at that setting. trust me bfbc2 loves trying oc settings :p also if you have to bump up the volts on certain progs then it aint stable is it really.
