Influence of PSU on OC ability - Page 2

post #11 of 20
Vcore form 1.47 to 2.2 Did you let the vcore as auto or something? Make sure you get a good read on them. If you read the vcore correctly, it should drop a bit when you do OCC. I think you may read the NB, which has base 1.5V.

No, thats the crappy part, its doing it all by itself... everything is set manually...short spikes though, but the nb and sb seem to be running 4.01v all the time, according to PC Probe.

Use the latest version of CPU-Z to display your vcore.. to see if its still jumping a lot. If so, I would try another PSU immediately, to determine if its your mobo or PSU.

CPU-Z is usually switching between vCore values and VID values O_o. It switches randomly each time I start CPU-Z. Dont know if its normal, but I assumed it is.

OCZ makes great RAM, and from what I've heard their other products are also great. I would recommend the OCZ, but know nothing of the Enermax. As for your initial question, you seemed to answer it by stating you had to drop the OC due to going SLI. IMO, get a quality PSU with enough power and then some extra in case you add something else (no overkill though) and you should be fine.

I'm an OCZ fanboy simply because of their warranties and customer service but so far I have no complaints about any of my hardware other than my Tempest is underpowered for my overclock but that's not a fault of the cooler since it works like it's supposed to. 8 degrees less than the stock cooler but that's beside the point.

I would check out HWMonitor for your voltages. If something goes completely far outside of what is acceptable I consider it a hiccup in the monitoring application and will then use other ones to see if they confirm it. If they do then I know I have a problem.

Now I don't own a 680i but is the northbridge voltage supposed to be 4v+ as the OP has said?

Nb supposed to be 1,35 stock but my psu thinks otherwise. And if I open up HWmonitor, the voltage sensors seem to crap out, and I cant see any voltage relating to vcore,nb,sb and such untill I power off ( pull the plug ) my system and turn it back on.

Another option is Everest if you haven't tried that already. It should give you a run down of everything as well. It's probably safe to say that you have some faulty voltage sensors.

:'(

Anyways, wich PSU would you recommend ?

I have a few in mind:

OCZ GameXStream - 850w
Enermax INFINITI - 720w
PC Power & Cooling Silencer 750w. Has treated me perfect, stable as can be. I've got SLI 8800GTS g92s right now, and OC on the cards and CPU/RAM, and it is fine.
