Q9450 OC / Temps / Settings

[jas420221]

I'm thinking of cancelling my X3350 when reading these posts. I was thinking about getting 450x8 like my old 65nm Q6600 could. Only then on default of lower then default volts. But it seems some have to ramp the v-core quite a lot to get those speeds. And when you ramp the v-core the cpu will consume 2x the normal wattage wich is not handy for my pc running 24/7 i'm running my Q6600 at 3.2 stock volts so i was hoping for 3.6 with stock for this X3350 but it seems thats not possible ?

2x the wattage? What volts and clock speeds will double the wattage?

All PSU calculators dont show that kind of difference....http://extreme.outervision.com/PSUEngin

Using the link above, at stock, my system uses 372W. I just o/c the processor and got 435W. Thats a smidge more than 50% increase, not 2x.

I know of a few people running a Q9450 at 3.6Ghz with stock volts all around. The issue is the board you get to run it on; in my case I got the P5E3 Premium, and it is a b!tch of a board for my CPU/RAM combo. I can run everything stock at 400x8, except for the RAM, it needs +.04v to be able to run at 1:1 with the CPU. If you want to run a CPU at 3.6Ghz 24/7 then this is the chip for you since you don't really any voltage at all; you just need to read up on the possible board you want to use, and look for the RAM that is performing the best with it. In the case of the P5E3 Premium, seems that the CellShock PC3-14400 is the most stable RAM.

3.6Ghz @ stock volts???

Do you mean "auto" for CPU voltage in BIOS? What is the actual voltage?

I'm at work right now, but I have seen [read] posts in different forums stating that they are able to run the Q9450 at 3.6Ghz with the vCore set to 1.20 in BIOS [1.168 in CPU-Z]. I will try it myself tonight when I get home. I will also try and locate the post where I read it.

Well, I was unable to locate the posts; but I was unable to get it up to 3.6Ghz at stock volts, I had to crank it up to 1.27v.


On a side note, for some reason the system is acting funny at 1600FSB/DDR3-1600. I dunno if I just tried to many settings and it threw the motherboard a curve ball or something; all I know is that I just won't go past 3-4hrs worth of Prime95 anymore. However, I was able to get it pretty stable to 415FSB with RAM running at 1245Mhz with 5-5-5-15 timings and 1.94v. I will have to wait a bit to post the settings from the BIOS because it is still running OCCT.
