Power supply responsible for limited OC? - Page 2

post #11 of 16
I've been using one of these for about two years now in my benching setup: http://www.newegg.com/Product/Product.aspx?Item=N82E16817153143 and I'm leaning towards getting a larger unit before too long.
This is what I'm currently running in my everyday useage build - Was using it for benching but now it's for said use and doing great there: http://www.newegg.com/Product/Product.aspx?Item=N82E16817703027

Can't complain about either one. As for the larger unit I have plans for, definitely going 1000W+ with that one when I get it.

I'll probably be going with a enermax or corsair +1000w psu next.

It looks like I can set it to 1.4 as long as I do it in the bios, if I do it with the ASUS software in the OS it shuts down.

On a side note now that I have the power I need, the temp that shouldn't go over 60c is the core(package in hw monitor) temp not the cpu temp, correct?

I am gonna shut down unplug the raptor drives, set defaults in bios boot back up then change the volts and see what happens.

Alright, this is your problem. Its highly recommended to not use the OS to change voltage, timing, clock, multiplier, etc etc values. Use the bios, or in other words, the lowest driver level. Using software to edit a bios and flashing is alright because you have to reboot the hardware. What happens with the software is that when your system is booting after POST and the OS is loading it is changing the voltages and clocks real time which creates instability. It will work for small changes like all OS OC software, but it has its limits. With bios changes, the hardware boots at the specified value at the lowest driver level and then attempts to load OS drivers. Its an overall better methodology to set and determine basic system stability when overclocking or underclocking. Your PSU can run all that hardware no problem.

And about your temp questions. Its all a matter of preference, as long as you are at least 10c~ away from the TJmax on load. Temps at 60c+ are alright. It depends how you like your system. Some like it cooler, so they will stop at their desired value. For me I don't mind running my CPU and GPU at 80c. Its not something written in stone with the exception of the TJmax and where throttling occurs (if throttling happens before hitting close to Tjmax). I remember Pentium Ds used to run hot (90c); could fry eggs on them.

If I set any of the voltages in bios that in windows make it shutdown, at load in windows it still shuts down.

At 1.375v, 250fsb and 18x, occt errors out after about 15 seconds. At 1.38125v(one bump), the system shuts down after about a minute at like 51c with everything else set the same.

edit: 4.5 ghz btw

Sry about the double post but...

I've noticed a couple times now with the new clock and voltage the asus software will warn that the 12v voltage is below 1v but when I check it it's like 11.63v. Warning sign about psu?

Very well could be,but again that Asus software is CRAP. Use HWmonitor or SpeedFan. I would either buy a $10 multimeter or PSU tester or swap a known good psu in and try that. No way you should not be able to use more than 1.4v.

And uninstall all of that Asus AI suite,it is known to be very buggy and unstable.
