Cez, welcome to PureOC and MIIF club.
Its would been nice if you can fill out your rig specs in the UserCP so we don't have to ask you what kind of hardware you have. Second, try not to use short hand to post your message because not many people will understand it. We have member around the globe on here, some might don't understand slang wording.
For example, I'm going to ask you what type of cooler are you using, stock air cooler or aftermarket, type or water cooling?
With your temps I'm assuming you're still on stock air cooler.
Let summary your problem;
1hr of Orthos is not enough to declaring stable, max load temps usually reach its max after 1 hour or so and it depends on which stress software you're using. So you should to at least 8hrs of Orthos before you call it a day.
Your current voltage settings are still at stock with 3.4ghz overclocked, if you want to stable or go pass 3.4ghz then you have to inscrease Vcore, FSB, NB...etc. Take a look at bios setting sample table.
My advise before you go any further, you should upgrade your cooler, 60ish degree at 1.17v. That is poor cooling.
Ok, I'm going to show you a quick trick to give you a starting point to get to 3.5ghz.
set every settings in the bios at AUTO except FSB (410), CPU ratio (8.5), set your RAM at its spec. The board will automatic taking everything for you, but the board will over voltage a little bit. Use Everest or Ai Probe to read all the voltages, write them down.
Now go into the bios change those voltage accroding to your note and work your way down to the lowest voltage but much pass the stress test.
Try it and let us know the result.
