Yah those things go for under 20 bucks a lot. Your brave going bd. I won't touch one for now. But you already have a rig ready for it. Good luck

4.5ghz with 1.360volts? Thats maxed out? No way.

Get that puppet with some 1.5v and you'll get close to 5ghz or even the mistical 5ghz.

Anyways 4ghz stock voltage 8 cores, i find it impressive.

Hey quick tip, go on AMD overdrive/whatever its called, and enable/disable CnQ C1E c6 thats stuff, i think you have to disable CnQ a couple of times, in order to disable the TDP protection ( thats why your frequencies are all around the place).

Yeah I built this system in march, only change was the mobo for stability from my 890fxa-gd70, almost went sandy bridge but dont regret it one bit. Currently I was tempted to return my asus chv since it is in the 30day return period with newegg but I really have no complaints with my 1100t, its a good performer! Does all i need it to do.

I want a BD because I cant truely believe my 1100T beats it in almost every bench I have seen, Its like a "I need to see it to believe it" scenario.

I personally want to OC it as a 4 and 6 core and see how that does overclocked, I havent seen a lot on that except some people say it does better that way too.

Codyodi---------------

If you can please bench it as a quad core and an hex core. Im wondering if you can get the overclock higher and with less shared aspects, might get closer to the 2500k? Some speculate that but dont think anyone has put the time into a max overclock, you might be able to get much closer to 5Ghz with only 4 or 6 cores. The idea in the quad is to disable 1 core per module, there are 4 modules each with 2 cores, thats how its made, I am just uncertain which they are numerically in the bios. I saw it somewhere but didnt bookmark it.

Hey bud, Id like to point out a few things for the BD overclocking that will help you reach higher clocks.

First and foremost you really want to do this via the Front Side Buss. It responds to this far better and will perform higher numbers by doing so.

1:BD responds to voltage in different ways than all of the AMD chips before it. You have to be careful as to much or to little is going to cause you grief. Its about finesse not force. A lot of people are hitting around 5Ghz at less than 1.5

2: Try not to exceed 2600Mhz on the North, they really haven't liked this so far from multiple sources.

3: Disable any cool and quiet and spread spectrum type options as these can hinder your OC.


Also El Gappo was kind enough to share with the forums his initial over clocking experience and results with the forums. You can find this in the AMD section.


Good luck!



EDIT: Also!!! Show me some memory benchmark love at different speeds and timings please!!!!! I will be forever grateful as it will be at a min another week before I can test my new one myself because of business trips.

As some others mentioned, try disabling Application Power Management (APM).

KitGuru FX8150 Review
Quote:
It is worth pointing out that the Gigabyte 990FXA-UD7 has no bios setting to disable APM (Application Power Management). Without this disabled, the motherboard will maintain the TDP limit when overclocking or overvolting above the limits. As a result APM will throttle some of the cores back to lower Pstates during heavy, multithreaded workloads reducing performance.

To get around this, we have to use AMD OverDrive software (above). We enable TurboCore, apply, then disable TurboCore … this in effect also disables Application Power Management.
See if you can get more performance out of it that way.
