My 1090t overclock potential?!

post #1 of 11
Thread Starter 
Hi to you all guys. My first post, and a right place for it smile.gif

A week ago I bought and assembled my Amd X6 setup:

Cpu: AMD x6 1090t
Mobo: Asus ma489gtd pro
Ram: Exceleram Black Sark DDR3 1600
Vga: Ati 6970
Psu: Chieftec CFT 750

I am currently on a stock heatsink and am truing to figure out whether to invest in Noctua NH D14 next week or leave things as they are. Now i am running my chip at 3.6Ghz on the stock cooler with voltage set in bios via offset mode to -lowest value. So far, it games at 1.392vcore fine and ran prime 95 for a minute or so without errors, but the temp. got to 60c so i cancelled the test. I tried 3.7GHz-4Ghz but the cpu required > 1.47 in order not to Bsod instantly and survive at least 20 seconds of Prime95 until cancelled by me due to temps. When i left all voltages on auto and just upped the multiplier to get 4Ghz, cpuz showed 1.50v under load. I started Prime, the temp. went fairly quickly 15sec or so to 59c and the computer crashed.

Now my question:
Can the Cpu behavior on a stock heatsink be in any way an indicator of what to expect on a decent one? If my cpu throws a bsod under stress test very quickly on a stock cooler, before I even see the temps rise considerably in Amd overdrive, is it likely to do so on a first class cooler?!
If that is the case, I would conclude that my chip is far from being golden and refrain from investing further...

Probably very well. An NH-D14 would be a great investment if you have the cash as it would keep temps down; Phenom II likes it cool, so the cooler you can run, the less voltage you might need. The stock cooler likely won't take you to 4Ghz.

Hey there, that seems very normal but A better heat sink will allow you to get better temperatures and in turn lower voltages. From experience however AIR is AIR, I've never noticed air temps making voltages significantly lower. Running my cpu with an h50 (higher tier AIR cpu cooler) has yielded that 4.0ghz needs 1.38 volts. 4.45ghz needs 1.58 to be stable on my chip and it fails prime 95 after a few hours, never bsods though. All in all you should be able to get 4.0ghz quite easily with a mid range cooler like the CM212+. Try running it at stock on the lowest possible stable voltage and estimate your potential from there (3.2ghz 1.17volts here).

thermaltake frio is pretty cheap and it comes with 2 fans with speed control.
i setup my friends 1090T to 4.2ghz 1.52V.

The NH-D14 would be a great purchase! OC'ing on the stock cooler is such a pain, it sounds like a beast when you try and push it up to load temps. Got myself a Hyper 212+ in the mean time till I can get all my water cooling parts.

imo i like the h50 it preforms for me the same as peoples dh14's reportedly do, costs less, is dead silent, the downside is it requires 2 headers, and was a pain to install properly. that may just be me though.

Hey guys. I bought Noctua 14 and am stable at 3.9 at 1.476vcore. But, i need over 1.5v for 4ghy and temps go to or over 55c. I left all voltages to auto except cpu vcore, only upped multi to 20, htt and all is default...confused.gif
