[QUOTE=Nemesys;2573644]I … This issue has been a major thorn since the recent build of my new system.
The board is ASUS P8P67 Deluxe with an Intel 2600K mounted. The BIOS is 1204.
I am no stranger to overclocking but this board simply will not overclock.
It appears that I do not have the ability to disable the [B]OC Tuner[/B] so the system automatically lowers the Bus Speed to maintain 3.4 GHz.
Does anyone have any input?
Thanks in advance.[/QUOTE]
New here, and new to OCing. This thread looks like a good one for me and to keep the thrust moving forward. I have read through the various replies, but have not had time to check out everything. My problem should be easy to solve, but …?
I started with the build identified below–using the post Rev B3 ASUS P8P67 Deluxe, a 2600K, and the ASUS BIOS that comes with the board (your might want to read ahead on more details of my build(s)). At this point, I am only interested in OCing the Turbo Boost mode using the Ai Suite II from within Win7, but also tried a got-nowhere OCing starting with disabling Turbo Boost, etc. (more later, perhaps).
So, back to my first attempt–just OCing Turbo Boost using Al Suite ll TurboV EVO–auto mode. I had no trouble initial trouble using my prior-to Rev B3 board. I easily OC’d to about 4500+ (103 X 44) MHz and, presumably, could have gone farther since stability was not a problem (see build(s) below).
Without trying to go farther (except with RAM), I was getting CPU scores of 11,000+ using the latest 64-bit Passmark performance test. Without OCing Turbo Boost, I was, and still am, getting 9300+ on this test. Both values seem to be pretty much par for the course.
As implied below, I was, given my limited knowledge, unable to get the OCZ RAM above 1066. I tried to get 1333 by upping the RAM voltage from 1.5V to 1.65V. I got a panic attack and subsequently could no longer use the method described above to OC.
Thinking something might be wrong with the processor I RMA’ed it. Shortly after I received it, my Rev 3B board arrived (latest ASUS supplied BIOS), and I rebuilt, including the change to indicated below to 8 GB Corsair Vengeance now running well at 1648 MHz (1.5V).
Everything, again, seemed just perfect, but, as above, I cannot OC Turbo Boost using Al Suite ll TurboV EVO–auto mode. I go through the steps and everything looks right including the way the auto mode works. However, I cannot get any OCing done–except that the BCLK moves from 100 to 103–which is fine by me given my goal.
One reason I am proceeding slowly is to learn about OCing. So, when using my procedure, the OCing results should be saved to BIOS–which happens and, thus, I can feed off the settings conjured up by Al Suite ll.
As before, I can not find any evidence that I have OC’d–using the latest CPU-Z–CPU-Z 157, the latest AIDA64 Ultimate, the Passmark test, Ai Suite 11 CPU monitoring, or the WEI (my processor score is 7.6, but was 7.9 when I originally could OC).
I have tried several things in the BIOS to get my processor OC’d. Most importantly, perhaps, I have tried with the OC Turner set to both OK and Cancel. After trying to OC, I find that the Tuner always ends up in the OK mode. I think that is why my BCLK moves to 103–a 3% OC. At least I now understand a bit about how the BIOS works and interacts with Al Suite ll.
Perhaps, I should increase the Vcore voltage to something above its current 1.280V? Would doing so likely cure the problem.
Here is my build. It’s my first, and I had no problems through setting up my RAID 0:
Intel 2600k (OC Turbo Mode to 4.62 GHz with prior-to Rev B3 board)
ASUS P8P67 Deluxe
ASUS EN GTX 470 OC
Cooler Master 932 haf
Cooler Master Silent Pro 850W
Prior Board: 8 GB OCZ Reaper @ 1066
Rev B3: 8 GB Corsair Vengeance @ 1648
64 Bit Win7 Ultimate RAID 0 on WD Caviar Black SATA 3.0’s
Pioneer Blu-ray Burner
Samsung DVD Burner
I would greatly appreciate any help you can provide.
