how phenom ii x2 555 black edition will bottleneck R9 280x ??

[Omar Moustafa]

Hi I want to upgrade my rig but I don't have much money & the Hardware in Egypt is very expensive...so should I buy r9 280x then buy fx 6300 within
3 months?? or should I buy r9 270x + fx 6300 now ??..I have 78lmt-s2p rev 5
& 2x4GB kingstone hyper..will a 500w psu be enough for r9 280x??..sorry for my bad English.

Your current AMD CPU is way underpowered for a R9-280x.
Rather go for the R9-270 and FX-6300 combo
How many amps at 12V does your PSU give? You need 34A for the R9-270x

Buy the R9 280X now ... worry about the CPU later.

And, your English is as good (if not better) than many Americans!

thank u for your fast answer guys & for your Courtesy Wisecracker ...i want to know what is the expected fps for a game like BF4??...& will the motherboard support fx 6300 ??...this is the psu Petrossa http://www.egprices.com/en/product/cooler-master-elite-v2-500w-psu-compufast

Your motherboard supports all 95-watt AMD FX CPUs, including the new FX-8370E and FX-8320E -- with a BIOS update.

Your PSU is likely a problem. It is 'dual-rail' with one 1x6-Pin video card power supply connector. The R9 270X requires 2x6-Pin connectors and the R9 280X requires 2x6+2-Pin connectors. It is advisable to use a 'single-rail' PSU like this model from your website.

BF4 likes 4 CPU cores. Have you tried to 'unlock' your dual-core PhII into a quad core? If you need some help, please advise. You roughly have a 7 in 10 chance at unlocking your CPU into a quad core processor!

At 1080p with Ultra settings (and quad core!) the 280X will get 40-45FPS and the 270X will get 30-33FPS. On high settings you are looking at 70-75FPS for the 280X and 55-60FPS with the 270X.

Clock speed on the CPU is less important than more cores/hyper-threading. The FX-4300 will work roughly as well as the FX-6300 (and the FX-83xx) in BF4 ... if that saves you any money, now or in the future.

Edit: I forgot to mention ... if we can unlock your PhII into a quad-core, in BF4 it will push your graphics almost as well as newer chips!

BF4 is highly dependent upon your video card (and 4 cores!)

thank u very much Wisecracker

You're welcome.
Here's some unlocking information for your CPU that I posted in this thread ...

Use the secret Gigabyte handshake to expand your BIOS Menu options (see the first page or 2 of the BIOS section in your motherboard manual), then ...

enter the Advanced Clock Calibration ('ACC') menu. ACC is supported by the SB710 and the SB750 southbridges -- doubtful support for the SB700 chipset.

Select [Hybrid] EC Firmware, and [All Cores] ACC ...

Note that you can adjust the ACC on a [Per Core] basis in the future when you wish to further refine the unlocking.

Gigabyte motherboards are bad to over-volt. You should take manual control of your voltages, and you should drop the juice in -0.0125v increments --- unless you plan to OC in addition to unlocking.

I unlocked a 550BE into a X4 B50 PhII quad while dropping the VCore -0.125v on a Gigabyte 700-series chipset. Ran 1.8v at load with the IMC/NB at 2400MHz. Power at the wall at load dropped from 179w to 128w with the rig under-volted and unlocked.

edit: For the most part I'd say 3 out of 4 chips will unlock, and likely run quite well in apps that need the additional cores.

thank u again my friend
