Hello I understand how to overclock my system except for what voltages to use. where should I start? I can get to a 266MHz Bus with the auto voltage setting, but no further!

I have a

Seasonic S12-430 PSU
Gigabyte GA-965G-DS3
E4300
2x512MB Kingston Value Ram
SATA HDD
PATA ODD

(Active cooling for North/South bridges)

Thanks for your help, I used to post on here frequently but I gave the PC to my girl! Now I gave her my new Vista OEM machine so i'm back playing with my "old" PC!
 
VOLTAGE SETTINGS FOR E6300:
-Set DIMM OverVoltage Control to +0.2v (might only need +0.1v, depending the quality of your RAM)
-Set MCH Overvoltage to +0.1 (leaving it at stock will likely work for moderate overclocks....so it's up to you. But higher OC's may also need a northbridge cooler for $20)
-Leave vCORE at 1.325v……..but it may need to go up as you go higher on the FSB. 1.325v is fine for moderate overclocks.
-PCI-e voltage can stay at Normal
-FSB voltage can stay at Normal, should be fine for moderate overclocks. Higher OC’s should go +0.1v
 
You can't crank it up at all with stock voltages? That is strange the e4300's usually do well on stock. I'd just bump up the vcore a little bit to like 1.35 and then see how far it overclocks. Don't forget to watch your ram and make sure you aren't overclockign it at all. Value Ram doesnt overclock at all. is it ddr2 800 or 667?

I just changed the voltage to manual and now it clocks at 271 (think it's actually 270FSB

I can't get 272 even with higher voltages (I used the above recomdations! I'm wondering about either

1, mem timings or

2, "black hole" numbers (combinations of BIOS settings that just don't work with no reason)

are reasons for no go after 271! Still at least I broke the 266 barrier.

Hi it's 2x 512MB DDR2

Kingston Value Ram

5-5-5-15 (it used to run 4-4-4-12 at 266) so would probaly go at 4's again.

it's DDR2-667 running 2x FSB

well it turns out that it was the PCI-e frequency that was to blame for the 271MHx FSB brick wall. after changing it to 102MHz it now boots and the CPU now runs at 2466MHz at 274MHz FSB

i have to be carful with the PCI-e frequency as too high and it does't detect my SATA HDD but does detect my PATA ODD so... Maybe I should get a quick PATA HDD or maybe even an add in PCI card. (I dont use the PCI-e bus for a GPU)

Hi got to 2.61GHz by tuning PCI-e bus to 109MHz voltages are still stock!

I really dont recommend the auto volts setting as this makes the heatsink run very hot even at lower clock speeds,

ok gotta go cos cute girlfriend (Jackie) wants a kiss and hug.
