AMD Phenom II x6 1100T overclocking + cooling

Hello,

I am would like to know how much I could OC the AMD Phenom II x6 1100T Black Ed. with the stock cooler. Could I reach up to 4 GHz? Would it be stable?

I am not really confident in OCing with the stock cooler. I would like to know what would be a good CPU cooler for the AMD Phenom II x6 1100T BE. I would like to reach at least 4.2 GHz with the aftermarket cooler.

Would the Cooler Master Hyper 212 be good enough? If not could you give me some suggestions? I am not looking for anything expensive (up to about 40 Euros, maybe less).



Here is the rig I will be using:

CPU: AMD Phenom II x6 1100T Black Edition
Motherboard: GIGABYTE 990FXA UD3
Ram: 2x2 GB Dual Channel DDRIII 1066
GPU: GeForce 9800 GT - I will upgrade in the future, hopefully
PSU: Corsair TX750
HDD: 1 TB
CPU Cooler: CoolerMaster Hyper 212+ - maybe something else, depending on how good this cooler is.
Target CPU speed: at least 4 GHz

Thanks in advance

While a 4GHz overclock for the Phenom 1100T is fairly typical and taking into account that the CoolerMaster Hyper 212+ is a pretty good cooler for the price; you may be able to achieve a stable 4GHz overclock. That will depend primarily the amount of voltage needed and the corresponding issue of heat, as the saying goes "Your mileage may vary".

Keep in mind that you have the option of adding a second fan in a push-pull configuration for better cooling with your current 212+.

I couldn't get mine to clock over 3.8GHz without bluescreening. Gave up tweaking the voltage settings bc I just wanted a running pc. Once I roll the server over to another box I will run another oc session and post the results.

PS. I have an ROG ASUS board and even the auto-oc stopped at 3.86..

unless you lose the binning lottery, 4.0Ghz for the 1100T with a decent OC'ing MB is a given. I have mine running at 4.26Ghz which is not uncommon and in the range of expectations (4.0-4.4Ghz) I would not even bother with the stock cooler, they give you the standard aluminum finned square with a single copper heat-pipe. (Why they bother sending out that with a 125w six core CPU with an unlocked Multi, I have no idea)

The auto OC (TurboV) or other is not going to give you the maximum OC , and 3.9Ghz is a typical OC for auto. You might try looking at where it takes your memory, HT/NB clocks as it does its thing. It may be that any of those are too high and keeping it from going any higher. The 1100T is a BE edition, try doing your self with just raising the multi. you will probably get to x19.5 or x20 multi with a voltage bump. then raise the reference clock 1Mhz at a time. once you find stability, you can raise the NB/HT multi , should have no problem running at 2600+Mhz (there is a performance increase in doing this, don't let others tell you there is not) Keep in mnd as well that a heavily OC'ed 1100T can be pulling close to 200W*** make sure you have a PSU up to the task******
as always, watch the temps.

The main reason I hedged on the stable 4GHz overclock was based on a quick check of the MSI 785GM-E51. It appears to have some issues with power regulation at higher voltages, at least according to one review ... although this is hardly conclusive.

Good point Miz,, it is not a an overclockers board. a bit of V droop.

****edit....Fixed!

So could I get a stable 4 GHz? Should I change the Motherboard, or will my current one handle the given "stuff"?

I would be using the corsair TX750 PSU and the mentioned cooler.

I don't get what you mean by pushing in a second fan.

@ red, what are your settings for the 1100T, including voltage and system specs. Thanks

What if I don't buy the radeon hd 6950, but get a GIGABYTE 990FXA UD3 mobo, would that ensure a better and more stable OC? I will have to use my friend's 9800GT, which wouldn't be that bad, would it?

1100T @ 4.28Ghz x21 multi x 204/ 1.52V

CPU: AMD Phenom II x6 1100T @ 4.28Ghz
Mobo: GIGABYTE GA-990FXA-UD7
Mem: 16 GB DDR3 Corsair XMS 3 (12800)@1670Mhz 8-8-8-27-24-1T

All CPU's are a bit different and have their own characteristics, but in all likelihood yes. the UD3's VRM phasing/power regulation is much better than the board you are currently using.

**** re-note the PSU comment above.

Isn't the Corsair TX750 good enough as a PSU?

Yes it is, I just meant you have been bandying this about for a while now so don't skimp out on the PSU when you go to order this stuff. Stable power is critical, thats all.

It means using two fans on the cooler to increase airflow, one pushes air into the cooling fins and the other pulls the air through. See attached.

Is that one fan or two fans?

I just found out that the cooler might not fit my case. Any other suggestions for the cooler?

You might consider something like the Corsair Hydro Series H50, especially if you're thinking about overclocking.

How the heck do you hook that thing on your PC?

BTW, do I need to change the liquid in the cooler once in a while?

I would agree, but for the type of overclock he is trying to achieve, he might as well just wait for the h80. Or go ahead and get the h70 if he can't wait. I mean honestly, the h50 is nice, but isn't a great performer.

A bit too expensive for what I need. Isn't there something similar to the CoolerMaster Hyper 212 +.

What about the ZALMAN CNPS10X Performa?

Ya know I had to do it Leek :haha:
