I can not pick them ppl will say i was cherry picking.. You have to pick them lol Get some ideas from the guys here as what you should run wink.gif

Anywho back to buggy Borderlands 2 and its 40% cpu use on 1 core and 30% on the others and 50% Gpu use.. and dropping from 120fps down to 80fps and no hardware use changing lol

for folks wondering on how to overclock these chips they are identical to the Bulldozer Chips. Piledriver cpus seem to average a higher overclock overall.

For the the folks with revision 1.0 Gigabyte boards with out LLC. You do not need LLC to get good overclocks. LLC is nothing special, the only thing it does it boost your voltage under cpu load to counter Voltage Drop. Nothing else, you can also combat voltage drop by setting the value higher in bios, with out LLC. However please be advised if your not using cool and quiet, your processor will not experience Voltage drop at idle. Thus Be sure to run Cool and quiet, so when your cpu is not loaded your voltage will not be higher than it should be. Cool and Quiet does nothing to effect a stable overclock, don't let people fool you into thinking you must turn it off to get a higher clock rate. In other words use cool and quiet, your room will be cooler, your power bill will be lower, and it will not effect your overclock!

For the people new to Bulldozer/Piledriver here are some tips to live by.

Cpu Voltage- 1.35-1.50 is safe. (you can go higher but you will need VERY GOOD cooling i would not exceed 1.6volts and remember anything past 1.5 volts your playing with fire)
North bridge Voltage- up to 1.4 is safe
Ram- Voltage up to 1.7 is safe

Bulldozer and Piledriver Clock higher the lower the cpu temp is. Try and stay under 50c full load. If your above 50c full load then you will not achieve as good of a overclock.

Keep a eye on north bridge Temp. The 990FxA north bridge runs hot, while it is safe up to 80c, make sure you have active cooling on it if your overvolting it. Not only does it help with stability, but you don't want to burn your north bridge out.

For Best results in pure clock speed, keep Hypertransport and North Bridge speeds linked at the same speed, also for pure clock speed keep these values at stock speed. Overclocking the Hypertransport and North Bridge will cut into your max Stable frequency. (not by much though and be sure to test with benchmarks what works best for you)

Last Note if your have more than 2 sticks of ram forget trying to run higher memory speed. You will be limited to lower memory speed, so go for best latency instead.

Good Luck and happy overclocking.

Thanks, but I still just cannot get over 4.6ghz no matter what I do sadly. Pretty sure it's my 970 chipset/old beta bios. At 4.7ghz, the temps and voltage get out of control (I need like 1.575v in bios for 4.7ghz). At 4.8ghz+, just pressing start on prime95 will instantly freeze my computer or instantly gives an "ERROR ILLEGAL SUMOUT" until it crashes in the next 2 seconds.

Oddly enough, a run of cinebench was stable at 5ghz with only 1.5v in bios (like 1.46v in windows) while 4.7ghz at 1.575 can't do a second of prime95.

you need more power phases, the 970's chipset boards don't have them, and if they do, they are not cooled.

8+2 power phase is a requirement for the 8XXX series and overclocking.

Yeah, the ga-970a-ud3 has the same exact vrm system as the ga-990fxa-ud3 (8+2 heatinked, same exact heatsinks in fact).

I'm betting my money on the chipset being the problem. Again, 990s were the ones meant to run Bulldozer and on-wards. Maybe hope for a BIOS update down the road or if possible at all, grab a 990FX chipset. I posted a link an good MSi board from Newegg, CompUSA has it cheaper, but you don't get the free 8GBs of RAM.

the heatsinks are different, but yes the vrms are the same.

try this - get your clocks to where you'd like them to be. then start with low voltages on everything your overclocking - each bsod or failed post, clear cmos and up the voltage bit by bit. you'll be surprised what clocks can run at lower voltages than you'd think. when i first started overclocking my 8350 i made 5ghz at 1.47 volts. i never thought it could do that so they were really high just for 5ghz but i brought them down more and it stabilized. then again i overclocked even more and now my 8350 is sitting at 1.54 volts

They are? They look the exact same to me o.o, unless I'm missing something which I may be.

Yeah that's basically what I did. I tried at first 4.5ghz and it needed 1.375v in bios to boot, and 1.45v in bios (1.4v in windows) to be stable. Now for 4.6ghz I need 1.525v in bios (1.46v in windows). Maybe I just got a combination of a bad chip and bad chipset/bios lol.
