I feel really stupid for asking this, but last week i built a computer:
Processor- AMD FX-8350
Fan- Cooler Master Hyper 212 Evo
Motherboard- Gigabyte 990FXA-UD3
RAM- 16 gb Mushkin Enhanced Redline 1866
Video Card- ASUS Radeon HD7950 Direct CU ii
Power Supply- Corsair TX850M
After getting my rig set up i decided that i wanted to overclock. So i went into the bios, went to my frequencty settings and was stumped when i found my CPU frequency as well as my memory frequency locked where they are. I was wanting to overclock both of these. Would someone please let me know how to get around this or be kind enough to let me know that you cant OC on this board.
What process did you use to overclock? I have this same motherboard but I have the 8150 instead. Want to get it to 4.1 atleast since I have it water cooled.
You start off with a high voltage and high OC on the CPU and work your way down or you start off with a low voltage and low CPU clock and slowly ramp things up.
I prefer the first method.
Set vCore to 1.45v and work your way down
Set CPU Frequency to 4.6GHz and if need be work your way down
To the OP... make sure you change your BIOS option for "CPU Host Clock Control" to "Manual" if you want to increase the "FSB" or set the "CPU Clock Ratio" to Manual to change the multiplier for all unlocked CPUs: http://www.overclockers.ua/motherboard/amd-990FX-gigabyte-ud3/12-big-gigabyte-990fxa-ud3.jpg
Worth adding that I have an FX-8350 running 4.6GHz at 1.4v myself on a gigabyte 990FXA-UD5.
I have the same issue. I've searched every option in the BIOS and still can't find anything. Maybe you have a different revision, assuming you own the board and are talking from personal experience.
You probably just have to change the settings for the core and the multiplier to manual, sould be right above the setting your trying to change. Also Avant96 my memory used to do the same thing, couldnt get it over 1333mhz. Turned out to be faulty memory, got new ones and easily went to 1866mhz and past 1910mhz on o/c.
anyone has any pointers to why my OC wont be stable at any settings.. PC freezes at any volts/clocks as soon as I start the test... I've tried many different settings and nothing works.. even at default bios settings Prime95 gives error... I got MSI 990XA-GD55 with FX-8350 + Kinston HyperX 1600mhz ddr3 memory.. I've seen ppl post they OC to 4.6-4.8ghz with 1.35v-1.45v.. Im stumped...
The + and - keys may be used most the time to change BIOS settings but on my old motherboard (Gigabyte G1 sniper x58) didn't use + and - keys so when I got my new motherboard I didn't know how to change BIOS settings.
Lol my BIOS looks EXACTLY the same. I have a MSI Z77 Mpower. I guess MSI uses the same UEFI BIOS style for all their mid range to high end motherboards.
Just wanted to see how everyone is doing with tweaking their 8350's? After a lot of fussing I've decided to accept reality. It seems my chip hits a wall at 4.7GHZ. 4.7 is GREAT, totally stable at 1.45v. However, to even go up to 4.8ghz it requires 1.52v!!! NO THANKS! I really wanted to hit 5ghz on my chip, but it seems I probably didn't win that silicon lotto, but there's always next gen eh?
Btw, my OC is done purely with multiplier. Have all power saving features turned off, LLC set to Ultra High. As well, 4.7GHZ at 1.45v is at load, not idle ;-) I think I bumped up my NB voltage from 1.1 to 1.11? LOL I was too scared! Wasn't sure what a safe OC on that would be? Any tips?
Look at me lying! just noticed on last stability test that CPU voltage actually goes up to 1.47! Anyways, still rock solid...
Wanted to also ask to see what you guys use for testing? I use Passmark BurnInTest and only Small FFT from Prime95. I don't use Blend or Large FFT because it's never stable, even at stock. Have researched and apparently FX chips are bugged in Prime for that? Anyways.
i dont know how it is on a Gigabyte board, but on a asus board it should be very easy to put the FX8350 all up to 5GHZ, logan did that in his movie 8350 oc vs i5 3570k oc. with just a few mouse clicks, like he said.Thats why i realy prefer Asus AMD boards.
