AVX does Integer just not 256bit Integer
AVX2 adds what XOP adds which is 256bit Integer

Pretty much tells you what is needed
If GPU Drivers and Video Game Engines exploited AVX instead of SSE2+x87 you would be seeing a better playing field 150 Megapixels vs 200-284 Megapixels

I have a question since you posted this. I am currently working with Visual studio C++ express 2010 and I was looking into that compiler. Had it already been optimized for BD or do I have to update it? Do you know anything about this? I am trying to learn program thats optimized for BD and I have amd's guide for it but i did see somthings about compiler updates for BD but i dont know if they been done with windows update or I have to do it myself. If you know anything about this please fill me in. Thanks

I dont know why you cant get that ht link at 2600mhz if you have BD cause thats its stock setting. There should be no problem getting that unless you bios doesnt support it. I really dont know about that. You do have latest bios correct? You are working with BD correct? I cant remember if you said I post so many things to help BD owners I cant keep track.
I would try to pick up that open box EVO asap if you can. Thats a good deal and asus has great support. Anyway let me know about those questions and ill try to help as best i can.

Yes, Im working with a BD FX8120, the phenomII was my previous CPU, and yes Im using the last version of the Bios for my mobo (0803), I guess I will have to contact Asus to also let them know about this problem with the speed of the HT/NB.

I dont even see any bios updates for that board on asus. I would definitely call them about that cause wasnt that board not supposed to support BD at first until they realized the pins on BD were the same? You should be able to get higher clocks on the HT than the CPU/NB.

I think that may be what the problem is. That board was never supposed to support FX. I could be wrong though, but I would contact them anyway about it.

yeah there are upadtes on the bios, they have released 2 bios updates after the BD came up, you can check them up here: http://www.asus.com/Motherboards/AMD_AM3Plus/M5A87/

the last version is v0803, the manual and the specs says its a AM3+ socket and it should support the FX CPU, the manual and the website says the following: AMD AM3+ FX™/Phenom™ II/Athlon™ II/Sempron™ 100 Series Processors

I did create a ticket on their customer service about this issue and see how they reply in the next days.

I would leave the voltage at 1.5v for cpu and cpu llc at ultra high. and try all different FSB, Multi, CPU/NB, HT and RAM clocks until you find something that works. Once you get a nice clock speed then work on lowering voltages. You just got to keep working at it until you find you cpu sweet spot. It does take time. I have had my chip since it came out and Im still working on find different clocks and voltages that work best. Most people enjoy doing this but it seems that you are just looking for a quick high overclock. If thats the case just up your multiplyer and cpu voltage until it becomes unstable then back off multi one step and increase voltage one or two steps and that should be good for now for a quick overclock. Take your time. BD overclocking can get very in depth and thats why most people like it. It takes time and patience. If you dont have that then just work with multi and voltage.
By the way, what is your stock cpu voltage?

I think I'll overclock later, going to be ordering a new kit probably a EK H30, but I have dilemma basically, I can buy the EK h30 supreme HF 360, or a bundled kit from the website. I don't know which one is better. Could you help me out? Also stock Vcore is 1.38, I guess, that's what CPU-Z is saying.

Microsoft C++ Compiler, I believe any version requires you to do intrinsics or use this option

I am not sure about Bulldozer support till version 11(Which comes out with Windows 8)
