:?: What is the max stable OC you could achieve (generally), with the E6300 CPU without Vcore increase?

:?: With the above OC, if you had DDR2 533 generic memory, would you have to lower memory speed to keep it stable. If you had to lower, how much would you assume is neccessary?

Thanks,

hmm, i got a similar question. After following the oc guide i have cranked my e6300 up to just under 2.5ghz. It is summer here & in 31 degrees on air it is idling around 45 & under two instances of prime it is going up to 55 (during day).

I didn't increase the vcore after the initial setting of 1.375. I watched it in speedfan & cpu-z & it didnt alter much, maybe down to 1.35. My question is, when should I bump it up? Someone says .15mhz for every 100mhz...Is that right? So 25x.15?

Just a word of caution: my P5B Deluxe mobo will set some pretty high Vcores if you leave it in AUTO. I went for a mild 3.0 GHz overcloxk and it set 1.4V Vcore with AUTO. Not too bad. WHen I set 3.2 GHz, it set 1.55V Vcore. That's really high (and hot). I am stable at 1.4375 Vcore @ 3.6 GHz and 400 FSB.

I'm idling right now @ 1.16V Vcore. I am at 2.66 GHz with SpeedStep enabled. That ramps up to 1.26V when I run Orthos.

So, monitor the Vcore with CPU z or whatever.

like you can hit 2.5Ghz on air cooling and without but it could be lower as the surrounding temp is cooler ,like here in india we have temps like 45-48 degrees during summer(peak ) so it's very hot but you are having much lesser temperature so may be it will be stable at higher clocks

I've managed to get mine up to 2.9ghz without many extra volts, it was still on less than 1.4v, with 667mhz memory too, with the memory clocking up to 830mhz. I had to use an extra 0.2v on the RAM, 2.0v instead of 1.8. Before increasing the volts it could easily do 2.5ghz, and I think It will go higher than 2.9 as well, but I don't want to damage the RAM.

Hi. I'm new to these forums. First post.

I've got a P5B Deluxe with 2 x 512 MB Corsair XMS2 DDR2 6400 and a E6300 also. In my case, I turned off the AUTO adjustment of the VCore, and configured it the normal value of the 6300: 1.28V. Then I set the FSB to 400 (2.8 GHz) and it was stable. Then, I tried to undervolt the VCore and ended with a stable value of 1.15V! Does it mean I'm the lucky owner of a rare CPU?

Intel realy did there homework with thier new C2D CPU's.

I can't see AMD :cry: catching up in the short term unless they dramatically reduce there CPU prices.

These E6300 CPU's are so powerful for current games, there is not realy any need for OCing :D

All you'll get is a few extra frames wich the eye can't pick up anyway.

I'm a noobie to the OC world and I couldn't believe how easy it was to overclock my e6300 on stock voltage. I did a modest 24% OC to get to 2.24 GHz. I set my 667mhz memory to 533mhz to get a 1:1 ratio. It's Prime95 stable.

I did this on an D975XBX which for a noobie like me isn't the easiest BIOS to figure out. Still, it was easy once I understood a few of the concepts.

I'm hooked on overclocking...and I'm not even a gamer!

Yep, that's why the C2D's are so great. Even people who have no idea should be able to overclock them with ease and not be so scared of the term.

I my opinion though, it is more accurate to say that we are just setting them to the speed they should run at :lol:

Uh ya at 2.8 ghz I can get my E6400 to 1.14v stable but at 1.08 volts it crashes.
