i'm going to oc my system i just built. the prob is i only have an antec 430watt psu. what should i set my stuff to for decent performance. i'm planning to replace cpu in 2 or 3 years if that makes any difference... i know a bit about computers, but just delved into bios for first time.
thanks!
core 2 duo e7300 2.6gh
2g ram (built to oc to 1000)
asus p5q se plus mobo
gt9600 512m (ddr3)
When overclocking an Intel system, there are two important things to keep in mind:
1. the faster the FSB, the better the performance
2. always run the CPU & RAM in sync (1:1 ratio)You don't mention what speed RAM you have but regardless, with the CPU at it's default settings (10 x 266MHz), the RAM should be set to run as DDR2-533. Your board is capable of 1600MHz FSB so I suggest you take advantage of it. Start off conservatively...clock the CPU at 7.5 x 400MHz (3.0GHz) with the RAM in sync as DDR2-800.
Are you experienced at overclocking? I'm downloading the manual for your board right now & will post back with some recommendations.

sorry, the ram is basic 800 stuff advertised to run at 1000. all i know about over clocking is what the mobo manual said (read cover to cover) and a little bit of tinkering in the bios, but not much.

OK, try these:
AI overclock tuner = manual
CPU ratio = 7.5x
FSB frequency = FSB 1600 / 400MHz
PCIE frequency = 100MHz
DRAM frequency = DDR533 / 266MHz <-- I'm unsure about this one. Go with this setting at 1st, then check your settings after booting into windows using CPUZ.Just download, unzip, then click on CPUZ.exe...click the memory tab & see what the FSB:DRAM ratio is. If it's not 1:1, it will probably be 3:2. If that's the case, go back into the BIOS & change the DRAM frequency to DDR800 / 400MHz. If you wanna check it before overclocking, the ratio will probably be 2:3.
CPU Spread Spectrum = disabled
PCIE Spread Spectrum = disabledCPU ratio = 7.5x
Intel SpeedStep = disabled

i followed all that you said master. (insert bow) j/k the ratio is 1:1, with the ram at 400mhz. think it would be alright if i sped up my ram to 1000 or so? if not why? (settings?) would it hurt to speed the cpu up to 3.2? (settings?) is there a desired ratio between the ram and cpu (and or other components)?
thank you so much!

is there a desired ratio that you could apply for the general components one desires to oc?
like cpu:fsb:ram:pcie ? or something like that? sorry, i don't mean to heckle you for answers.

Intel systems (except the P4 & it's derivatives) should be run with the FSB:DRAM at 1:1. The P4 was an inefficient design & performs better with the RAM running slightly faster...usually 4:5 or 5:6.
Early AMD systems performed best at 1:1. AMD systems since the 1st A64 don't have a FSB so there's no ratio to recommend. Generally, you just run the RAM as fast as possible.
There are a few constants for both systems. It's best to lock the PCI, AGP or PCI-e buses at their defaults:
PCI = 33.33MHz
AGP = 66.66MHz
PCI-e = 100MHzOne thing I'd like to add is that some sites/forums refer to the ideal ratio as 2:1. That's correct as long as you understand that they're using the data rate numbers rather than the actual frequencies. For example, your CPU is running at 1600MHz QDR FSB & your RAM is running at 800MHz DDR so that would put the ratio at 1600:800, or 2:1. Technically though, the ratio should be calculated using the frequencies, just as CPUZ shows it. Your's is 400:400, or 1:1.
"would it hurt to speed the cpu up to 3.2?"
All you can do is try. Just raise the multiplier from 7.5x to 8.0x & see what happens. You *may* have to increase the CPU voltage though. Do you know how to recover if the system becomes unbootable?

uhm, no. apparently my mobo has a "crashfree bios" deal. it says a flashdrive may be used, but it must be smaller that 8gs. well, mine's 8; can i put my current bios on a cd instead as long as i set my dvd drive to boot before my hdd? so two things 1) recover bios 2) can i put my current bios on a cd
