The gigbyte GA-990FXA-UD3 motherboard is revision 4, updated to the latest BIOS F2.
I've been following this guide http://www.overclock.net/t/1140459/bulldozer-overclocking-guide-performance-scaling-charts-max-ocs-ln2-results-coming which someone overclocks his chip. Yes i know the 8320 is not a bulldozer, but i heard someone say you can just use this guide anyway.
Here is my rig:
AMD FX-8320
Gigabyte GA-990FXA-UD3 rev. 4
AMD Radeon memory 16gb 1866MHz
Windows 7
CM Hyper 212 EVO
if there is any other info you need, just ask
BIOS settings:
Disabled performance boost, disabled power saving options.
Here is what I did. I disabled perf boost, and power saving options, then i upped the multiplier to 20-something so it was at 4.4GHz, and had no problems. Then i lowered the voltage until my computer failed to start up. I kept it at the voltage at which the computer started up, and ran Intel Burn Test. The comp froze on IBT, i guess because it was an unstable overclock, so I increased the voltage until i found the voltage at which IBT ran and passed for 10 minutes. That voltage is 1.368V.
Then, I was at the part of the guide where he says to change the Host clock frequency from 200 to about 230-250. And then he was vague. This is what he wrote:
"Now you want to tune the finer things, and increase the host clock(HTT/FSB). So lower the multiplier of the CPU, and increase the host clock, something like 230mhz to 250mhz is a good point to start. At this point the CPU-NB multiplier needs to be changed, please make sure it’s under 2.7ghz. At this time HT multiplier needs to be changed as well. Also your DRAM multiplier needs to be changed."
I increased the host clock to 230MHz, but left the CPU-NB multiplier on Auto. There wasnt an option that just said "CPU-NB Multiplier" it was just setting the NB frequency. I also left the HT on auto, and changed the DRAM back to its original setting of 1600MHz. For those of you with a similar motherboard or bios, basically this setting was something like "Memory Profile" and i put it on Disabled, instead of on Profile 1 which sets it to 1866MHz.
So increasing the Host clock increased the Memory's frequency. IDK what it did to the NB frequency or HT frequency. He was kind of vague.
But after increasing the Host clock frequency, the computer did not boot up.
Any input?
