make sure ure dram spec is 1:1 not 4:5

you can start HERE

guys, quick question..

if my proc(e6300) can run stable @ 3.2ghz (460x7), it should be able to run stable at say 475x6 (2.84ghz) rite?

or is there a fsb (not total speed) limit to each processor?

oh well.. i guess my mobo is the limiting factor then. I always thought that it was my processor.

My rams can run at 475 speeds (memtested them using the 4:5 divider) but my system wont be able to last in orthos for 5 seconds at 470x7 no matter how much vcore i pump in.

I guess I should just stop this obsession of crazy-overthetop overclocking and settle at where I am rite now. 430x7 @ 1.25v.

Do u really need 1.40 v to run at 3ghz?

Whatever it is, 1.4v is still within 10% of the default vcore. 1.55v would be overvolting your processor.

Note: I do not take any responsibility for any failure, explosion whatsoever coming from direct, indirect, perpendicular use of the rated vcore!

anyway, try playing around with your vcore, you 'should' be able to hit 3.0ghz with less than stock vcore. Mine is 3.0ghz @ 1.25v

Here's a good guide for overclocking e6300 (or any other conroe for that matter)
3.0 GHZ easy

That is pretty much relaxed timing already.

Btw, for gigabyte mobo, to adjust ram timings, press ctrl+F1 in ure bios. Then go the overclock page(intelligent motherboard control or something like that). You can now set the timings for your ram.

wah.. didnt know u still updating..

anyway, here's mine.

Oopss.. forget to list down.

E6300 (470x7)
Gigabyte DS3
1gb KVR DDR667
Thermaltake BigTyp VX

Err.. no actually. I thought anything below 2.2v is acceptable not to use any ram coolers?

Dont take my word for it. Wait for a sifu to clarify the fact. IIRC, I read somewhere in the VR-Zone forums something about no active cooling required to cool off the ram.

Btw, i do have a 120mm side fan blowing towards my mobo though. Im pretty sure it would 'cool' down my ram to a certain extent.

cpu or proc with 3.25v? prolly instant death? I have read that you should keep your oc to within 10% of the default vcore. Say for c2d's (most of em) the default vcore is 1.325v, so +10% gives you about 1.45v. That would be safe. IIRC, the ultimate max would be around 1.55v for c2d's on air cooling that is.

The ram @ 2.2v will prolly depend on the rated speed. Some performance ram are rated @ 2.1 - 2.2v. So running at 2.2v is fine. However, if the rams are rated @ 1.8v, I dont really know exactly. As a rule of thumb that i follow (which might be dumb), anything below 2.2v is okay. The lower the better though.

There's an interesting rite up about in VR-Zone HERE and some relevant info in TG Forums HERE (you might have to read a couple of pages of this one)

Good luck

what in the world are u talking about actually? Would really love to help but im really clueless here.

To answer ure earlier question (if you still havent got it) to adjust your ram voltage, please use the Vdimm option in the intelligent motherboard tweaker menu in ure bios. normal is 1.8v, +0.1 = 1.9v etc etc.

Obviously im not gonna use that for day2day. its only for benchmarking purposes. Heck, i think i dont really need to OC for day2day usage. But its just that I can run @ 400fsb with 1.1875v, makes it worth it to leave it at 2.8 for day2day.

I think its not Hynix. Hynix chips are only for KVR 533? No? From the ddr2 ram list website, DDR2 667 are elpida chips.

Okay Cyber, why dont you tell us @ what speed are u running at? whats ure vcore, vmch, vfsb and vdimm? Have you disabled all the 'enhancements' etc?

And not forgetting what is your coretemp, not the one reported in easytunes.

To be honest, youre settings looks okay

The only thing is to probably bump up your vcore a bit. Your planning to run @ 3.44 ghz, which is quite high. I've seen ppl pumping like 1.37 - 1.4v to reach 3.4ghz with an e6400. That being said, every chip is different.

What is the rated vDimm for your rams? As it is a DDR2-800, Im pretty sure ure ram could easily hit FSB 450 or even more with the rite vDimm. Maybe even DDR2-1000 Well, just to be sure, run a memtest for your ram as per the link i gave you. If it could pass memtest, you can rest assured that it's probably not ure ram.

Just curios, the CPU temp you gave are coretemp or bios temp?

@ Cyber,

Oh well, at least u still have a chance to hit 3.4ghz. Im stuck @ 3.29ghz max SUPER PI 1M stable.
btw, good temps for your setup. I actually have the same case and cooling as u do and I had quite mediocre temps before i added a fan @ side panel.

Have you tried running memtest for your ram yet? Can prolly try a more relaxed timing of 5-5-5-15. There is a good guide for overclocking the e6300 HERE

You'd be damn unlucky if your e6300 can't run @ 400 fsb. Its really rare! Anyway, go through this thread HERE for some other tips (like disabling usb legacy support or something). BTW, which bios are u running at?

it just means that your overclock is not stable enough. Im really out of ideas to be honest. Have you tried all the tips in the DS3 FAQ from the xtremesystmes forum link I gave out earlier?

I'm probably going to slow down in this overclocking business and start to enjoy more of my 1 month old C2D rig. Tired of tweaking it already actually. Started with

Stock HSF > THermaltake BTVX > Put side fan to improve airflow > Substantive Bios version testing > Tweaking and tweaking Bios settings > Add ramsinks to my BTVX > Lap my heatsink > Lap my processor (void already warranty ) > battled with the stupid push-pin mechanism > bought dangerden screws from kingmaker bulk!

I guess I should stop now! LOL But before I do, I would just like to contribute back to the community what i've learned in this one month, hopefully someone who just starting to OC c2d like i did, could benefit from it.

Dont forget to read our very own fundamentals of overclocking

Based on my experience, if you dont ask the right way, you'll probably be asked to do a google search I just hope I made your life easier by listing down the quality information that will aid you in overclocking your C2D.


To those who just started, good luck aight!

Updated my post already. Do i hear links for the ASUS P5bs?

Eh.. even vdroop oso not that high la.. 0.112v vdroop is very high. What mobo are u using again? Usually vdroop around 0.02 to 0.05v.

Have you disabled the EIST in your Bios?
