So what's the deal with Bulldozer mobos? - Page 2

post #11 of 19
Bulldozer will work on all socket AM3 and AM3+ motherboards. I just tested a 990FX board with a 890FX with socket AM3 and AM3+. There is no performance gain whatsover seeing 990FX chipset is essentially the same as 890FX. The boards overclocked the same with same CPUi/ hardware and benchmarked identical.

990FX gives 1 more POCIE slot, SLI compatable and SB950 gives more USB headers and 6 x 6G sata. There is no radical changes between the chipsets.

I don't believe that is true. I'm fairly sure only select AM3 motherboards will accommodate BD through a BIOS update

You tested a 990FX board with a 890FX... Makes no sense...

There will be a performance difference with an AM3 8-series and an AM3+ 9-series with Bulldozer.

That goes for AM3+ 8-series, it will perform better on the 9- series, but the difference is minimal.

Nope, I tested a 890FX and a 990FX Motherboards = performance. The is no difference in performance with 990/SB950. The entire makeup is the same with exception to 1 more PCIE slot, more USB headers and more 6G sata........ Both 890FX and 990FX motherboards will perform the same with bulldozer(socket AM3+).


Both boards were socket AM3+. If you relax and comprehend......., some 890FX are AM3.


The only negligible difference is 6.4GT/s hyper link over 5.2GT/s. I put them under benchmarks and extreme overclocking. No difference and there is nothing in 990 chipset that benefits Bulldozer.

I just finished the 890FXA-UD5 and 990FXA-UD5...........

Okay, let's just get this straight: were you using a currently available Phenom II AM3 CPU or were you using an engineering sample Bulldozer CPU that somehow leaked?

If you were using a currently available Phenom II, it makes sense that you had the same performance on the 890FX and 990FX motherboards. However, AMD has stated before that Bulldozer CPUs will operate optimally on new 9-series motherboards with true AM3+ sockets; however, certain (but not all) existing AM3 motherboards will be Bulldozer-compatible via a BIOS update, but will likely not match the performance of the newer motherboards with a true AM3+ socket and 9-series chipset.

Thanks for any help.
Bulldozer will work on black socket AM3+ based motherboards.
Phenom 2 works in this black sockets so you can buy a new mobo and shuve the "dozer" when it is on the market later.

AMD has also launched the new APU Llano stuff that uses a different socket ,this meaning new motherboards and no backward compatibility ,as it s new.

LE: This new mobos seem to have better VRM-s and higher overclocking capabilities .They also feature official SLI support.So they are quite attractive.

isn't there a thing with the 890FX AM3+ boards on voltage regulations? i remember seeing something on how if a AM3+ chip was used on a 890FX board wouldn't beable to have much voltage or voltage control over it limiting the AM3+ Chip, while the 990FX will give full ability in terms of Voltage on AM3+'s aswell possible better results on the Phenom II's.
