Yippee! I made it to 3.6 Ghz under a 125 watt max power envelope! Pretty happy, but curious to see if I can push a little more wo/ busting that wide open. So far temps look to be under 60C load in a Fractal Design Define R3 w/ an internal exhaust 580 during BF3! I think I would be comfy with 70C load though...also wonder if it would improve the gameplay experience any.
I have been trying to overclock this setup for the last couple of days and it has me going through loops. Probably due to the fact that I am pretty green at overclocking, but know just enough to get in trouble.
So to the story... I started out at 3.2ghz (160 x 20) / 1.2 vcore / 1.125 IMC and was getting an average of 59 seconds / 44 gflops with IBT on high, 50 passes.
If I even bump the BCLK a couple digits it goes down quite a bit to like 29 or so gflops and takes about 110 seconds. Jacking up the vcore and IMC do nothing to change this, but do seem to make it worse I have had it as high as 1.3 vcore / 1.25 IMC which should be more than plenty for 3.4 ghz from the googling I have done.
Speed Step / C States disabled
All voltages set: 1.2 vcore / 1.125 IMC / 1.8 PLL / 1.5 DRAM
Might also be faulty ram.
Or it can't take those clocks seeing as they're 1066 stock. Ah sorry that is your old rig(edit).
Hmm, maybe test it with something other than Intel burn test, because that isn't right at all.
Even at the 3.2ghz I have run the voltages up to 1.25 cpu and 1.2 imc and everything remained the same I have tried that at different frequencies as well going up to 3.6ghz. On several occasions increasing the voltages have made the gflops worse ??
I am going to run memtest now for a bit to check the memory though and will report back on what is happening with that.
Here are some screen shots of some testing I have done in the meantime though. There were several runs for each frequency and all the results are typical of what can be found in theses singular screen shots. I didn't have any stability issues up until the 3.6 at which point I had to increase the vcore a little and sent it through 4 more sessions of IBT at 5 passes each. The part that gets me throughout the testing is that the gflops never change even thought the frequency does?
