Best performance with overclocked 3000+ Winnie

[dborgill]

Ok, got the overclocking going on the 3000+ but I am a little confused.

I understand the lower the HTT so it opens up more headroom but why would you ever want to add more voltage to the CPU and RAM? It doesn't seem to affect the Ghz/MHz speed at all...

Also, is it better to run (in my case) a 1:1 ratio with FSB and RAM reaching only 2.1 GHz or lower the HTT to get a higher GHz? (Around 2.4 Ghz)

 

[nick1985]

more voltage certainly yields higher OC's

 

[canadageek]

higher voltage allows the transistors to switch faster, allowing higher frequencies.
only run the ram 1:1 if it looks stable. you can run it 1:1 with overclocking ram at higher fsb speeds, but i wouldn't risk it with cheap ddr400 modules.

Ok... so when I raise my voltages my mhz do not go up any higher...

When would voltages come into play? Using the 1:1 overclock or the lowering the HTT and raising the FSB?

(Sorry, never overclocked CPUs before)

after you raise your voltage you have to try to raise your mhz again because usually the ceiling will rise a little bit...

So the default voltage for the 3000+ 1.400 -- Would 1.55 be a good max?

Check your specs with MBM or something for actual vcore, but you should be able to get an optimal overclock with 1.5V, I have that 9x285, HTT x3, mem at 166/divider. Your temps might get a little to high at 1.55v, the lowest voltage you can set with a maximum overclock that is stable is the best way to go....

Cool -- Now that is CPU voltage right?

What is your GHz/MHz with those settings you have mentioned?

I am doing 9x260, HTT x 3 mem at 133 divider (My DD400 2.4 CAS comes in tomorrow), 1.40v and I getting 2.35 Ghz

you should be ok to do htt x4 being that default is x5 (which results in 2000). for you at 260 and 4x htt you would be hitting 2(4x260) or 2080. i run my a64 3000 at 1.5v 267htt at 4x for perfect stability

What GHz is your currently running at then? 2.08 Ghz?

 

[BlindBartimaeus]

You should get to a minimum of 2.4 with that. You need to lower your memory speeds to max 166 or something and raise the fsb up another 33 mhz. Don't forget to put your HTT to X3...you should be golden at that point. Repost back young man.

mine is running htt 267x4 or 2136. ddr is set at 5:4 which i believe is ddr333 max if i remember correctly, so it is running around 214. i tried other things like running lower htt with 1:1 mem and lower htt multi to 3x and going huge fsb but for me have 4x htt 267 resulting in 2403mhz has been most performance boost while keeping in constraints of stability.
