Increased multiplier effect on Intel QX6800

[Capulet]

I have an Intel Quad Extreme QX6800 at 2.93 GHz. As of FSB I could take it easily to 3.4 Ghz, but I would not necessarily change the memory core and therefore wished to make use of the multiplier. Default is set to 11 x 266 Mhz in the BIOS, when I increase to 12 x 266 Mhz, the BIOS is also on and after the restart, the result (3.2 GHz) as well as properly in the BIOS inside. However, if I run in Windows Prime leave, it only clocked up to 2.93 Ghz. Temperatures are always in the green zone that is because it still had much room to grow. What I also wonder, is that the automatic Vcore is set at 1.415 V in the BIOS. I wanted to set in the next days a GTX560 or GTX570 and therefore thought it was a sensible thing to overclock CPU a little. Do you have suggestions?

Vice VCore in the BIOS manually to the one - do not let it on auto. You will certainly need less. The Mhz bring it alone nor the high FSB. For much bandwidth also important if your system has more exploration that you want. Especially if you retrofit a graphics card from this format. Why will not you go over the FSB, I do not understand where the problem lies. The problem is one that I do not know what I except Vcore and Memory Core must be observed even on the other hand, I do not know how much my memory holds out, how much buffers ready you should and what should be the end of Memory Core.

So if you want it right, I suggest you first read a few how-tos. Why does not the multi problems, I do not know you have not played several programs CPU-Z, Everest, etc. You simply lowering it on and on and test it with Prime or Intel burn tests. FSB overclock I believe would not help much. The QX6800 is there enough power. However, if you increase the FSB the RAM part changes. Set the RAM divider is not the RAM comes standard on its clock. And by multiplying on overclocking makes more sense than raise the FSB, if you open multi NEN. Vcore always too low as possible. If the CPU is stable with the voltage can test even with Prime95. This could fry the CPU.

Cannot imagine me with the best intentions there is nothing really cool the CPU is not so, ie, a top air cooling you definitely need to go there. The Rams are rather secondary, because I do not think that you have a Ram, which is slower than PC2 5300, which indeed are 667Mhz, allowing for a FSB of 333rd and one or the other should as well Mhz are still in there. Just write something for a system you have, which makes it easier. This is totally correct, this is the board, but I see no option for the ratio could be set out as 2:3 or 1:1 etc. My system: MB: Intel D975XBX2, Processor: Intel QX6800, CPU Cooler: Asus Silent Square Pro (approximately 30 degree C in idle vcore at 1.3v at 13x266 MHz). Ram: 2 x 2 GB DDR2 800 PC2-6400 OCZ and 2 x 1 GB DDR2 800 PC2-6400 MDT.
