Its finals week at college so this overclock is going to be slow but so far I am at 2.1 ghz and entirely stable. I had to increase the vcore or the computer would crash. I discovered my ram is terrible for overclocking, at stock timings it only goes to 212 fsb before becoming unstable. Timings are 2.5-3-3-8. Right now I have the divider set to 1.8 something.
My next steps are to increase the memory voltage, lax the timings a little, set the divider to 1.66 most likely and see what I can do from there. Temps still fall below 40 C so all is good.

I do understand that a 1:1 ratio is the best but if thats impracticle should I conitinue on the path that I am taking?

One more thing, if my ram doesn't have heat spreaders what should I keep the vdimm at? (RAM will be the next upgrade).

up the voltage for the ram a step, and set cas latency to 3. that will let you o/c with it a lot.

So I went and upped my vdimm one notch and changed my latency settings to 3-3-3-8. I removed the divider so that I could find the max fsb for my ram now and currently am at 235 without a single instability issue. Heres to hoping it stays that way! I am going to keep pushing it because the temps are still great!

Can anyone answer my ram question: whats the highest vdimm setting I should go with if my ram has no heatsink?

That ram would probably be happy with no more than 2.7-2.8V. You should be able to get that cpu to a very healthy stable OC with no worries. If ya temps are OK then with a little vcore added then 2500 - 2600 should not be a worry. Adding more volts will make the temps go up dramatically so always keep an eye on your LOAD temps. Prime 95 would have to one of the quickest ways to load your CPU to check your temps.

Your temp will come to its max pretty quickly, no more than a minute really (in my case about 5 seconds or less) and should stay around that temp for hour after hour as long as you have a descent amount of air flowing through your case. In some instances it will creep u a little.
Speed is everything so if you have to keep that ram on a bigger divider to get the cpu cranked up then so be it, on other things if you have to loosen ya ram timings to get the ram cranked up then do it. CAS 2.5-4-4-7 and see how it runs. You could always try a 8X multi to get ya ram speed up on a particular divider, there is lots of ways to get the speed you are looking for. Differrent BIOS versions will yield different results, some like different timings and some will just dislike the loose timings. This might not be as apparent with your motherboard but look around and see if there is any compatibility issues with your bios version and the cpu\
am.

good luck and enjoy

vdimm 2.9 no higher with what you got, contrary to most 1/1 not much differance if you use a divider, 1/1 will hold your cpu back unless the ram can do upwards to 240 to 250 fsb, with a divider you will take the ram out of the picture and let you get more out of the cpu, the higher hzs will give you more performance.

So I began to continue overclocking but as soon as my fsb reached 240 system crash, had to use reset the cmos. I changed the ram divider to see if it was holding me back but no. Should my cpu really be holding me back already? What should I try next.

Whats the highest I should go with my vcore?

ok I will stay around 2.5, I was afraid because the numbers went red in my bios as soon as I reached that number.

Any idea why my computer refused to boot when I reached 140 fsb?

I use a ram divider like 1/2 to begin to figure the max you ram can go and than work with it with the multiper also my sure that your htt mutiper is not to high when hitting htt300 you want it 3.
