HOWTO: Overclock C2Q (Quads) and C2D (Duals) - A Guide v1.7

[graysky]

? You would benefit from the machine being overclocked. Raising the FSB on a locked chip is the only way you can overclock it. My point is that if you're intentionally lowering the multiplier and raising the FSB to achieve faster memory timings while holding the overall clock speed constant, you're wasting your power and stressing the machine out for no reason. Does that make sense?

didnt know 6300 had locked multiplier. but 400 fsb from what i read isnt that bad on these chips people have been getting 450+ on stock cooling and 500+ on aftermarket. so i guess what im saying is if i put fsb on cpu at 400 and memory at 1:1 then this would be the best scenario, 2.8 on cpu and memory full speed. that is if the temps are good and system is stable, is this a correct statement that this would be the best. and if my system is unstable at these settings then put the memory to 667 cpu to 333 fsb and 1:1 and try that. if that isnt stable then go w/ amd for the rest of my life. also thanks for your help not trying to argue just get the best all around idea on best, 2nd best, etc....

ok well im going to ask it like this. e6300, asus p5b-e, patriot pc-6400 (d9 chips), what would be the recommended setup. speed, settings, everything, im looking to overclock what i can, where i can to gain speed. yes i want as most speed as possible even if i have to run the memory at 1mhz. thanks for any input. once again how should i do this, im asking and all im going to say in response is thanks and not ask why any more. once again thanks for the help.

I just want to say I'm a Happy Camper Now

This topic is perfect it has all the missing information i was looking for

now my system is stable at 3.333Ghz (FSB333x10) v1.32 (factory max 1.352) with RAM at 1:1 667Mhz (333) v2.0 (factory max v2.1) timing 4-4-4-10 (factory SPD was 4-5-5-13 at 333Mhz )
I'd have never guessed going Down will actually bring performance UP to Max
Factory Stock was (2.93Ghz) 11x for the CPU and 800Mhz for the RAM, it was stable at (3.2Ghz) 12x and 800Mhz RAM but voltage was over factory standard 1.362
So Downgrading actually resulted better off, since it is below factory standard, yet it gained me over 400 Mhz from stock 2.93Ghz
of course i picked to remain at 333 since it is 1:1 ratio with RAM
but i did go higher up to around 3.5Ghz with some weird FSB but those were unstable

Also even at my current setting 333x10 and 667 it was unstable with lesser voltage, originally it was at v1.31 for CPU and v1.95 for RAM
both Post and went all the way into Windows properly, but after like 30 min, or after it switches to some high resources software, then it crashes.

After upping the v. to v1.32 and v2.0 respectively now it's rock solid.

The only thing that annoys me is that i feel like i'm wasting my PC6400 LoL cuz now they are operating at 333 instead of 400

I tried and failed clocking the RAM to 866 (real 433), so my only option was for 333 for max stable performance.

So i'll have to say Thanks and Kudos to graysky for such a great detailed info. in this topic.


Oh!! and forgot to add...

Still using Stock HSF, and iddle Temp is 49c and Full power Temp is 57c, Average Temp is 53c

and i'm using that Awesome RMClock utility, the PowerManagement feature it offers beats everything i've seen so far, and it has accurate Temp monitor as well as voltage, fsb, core, and throttle. Not to mention the monitoring options it has, for both CPU and OS load.

and i didn't know about this great software until today, when i came across this post LOL

 

[graysky]

Glad to hear you found the guide useful! Great job on your o/c too.

Have you considered 11 x 303 ? Might give you cooler NB/SB temps if you can do it @ a lower voltage. Also, don't feel like you're wasting your RAM by running it @ a slower than 400 FSB. I too have DDR2-800 running @ 667.

 

[AllGamer]

i was considering these... still testing more combos out

.... this is a work in progress.

Goal, trying to maximize RAM bandwidth, and maximizing overall system performance, at lower temp and voltage than required.

Faster CPU doesn't always bring faster overall system performance.

RAM is rated good for 270, 333, 400

266x11 = 2.93 <--- Stock
266x2 = 532 (2:3 ratio ) <--- Stock

266x12 = 3.19 <--- OC (stable)
266x2 = 532 (2:3 ratio ) <--- Stock (stable)

270x13 = 3.51 <--- OC (stable but it needs v1.4)
270x2 = 540 (1:1 ratio ) <--- (stable)
but lost performance due reduced RAM bandwidth, 3.33 is the best so far

270x13 = 3.51 <--- OC (stable but it needs v1.4v)
405x2 = 810 (2:3 ratio) <--- (stable)
same as above, the RAM at 810 did not help much

333x10 = 3.33 <--- OC (stable)
333x2 = 666 (1:1 ratio) <--- OC (stable)
http://service.futuremark.com/compare?3dm06=2491946

366x10 = 3.660 <--- OC (failed)
366x2 = 732

366x11 = 3.663 <--- OC (failed)
366x2 = 732

400x9 = 3.60 <--- OC (failed)
400x2 = 800

400x10 = 4.0 <--- OC (failed)
400x2 = 800

... tried with 303x11 no go, it failed, due the RAM
this OCZ Gold seems very picky, it only works properly on 270 or 333 or 400 (+/- 10% variance)

 

[graysky]

Weird... oh well, enjoy your system

i wonder why this topic is not a Sticky, it's so much better and detailed than the AMD one that is stickied

second that!:thumbsup:

Graysky - Question: The guide reflects comments about DDR2 and worrying about dividing the frequency by 2... What is the scoop when using DDR3 ...?

And this definitely would benefit from a sticky, I agree.

i think the most important question is.... Is your Mobo going to support DD3 ?

 

[ALECUBA]

so wat would be a good config of my memory to be best for my cpu...underclock it to ddr2 800???timings??? or overclock it? now its at 1160MHZ

 

[graysky]

You'll need to do some experimentation on your own with different settings and timings. Pick a group of apps you commonly use like I did in this thread and run some benchmarks, change settings, repeat. You'll probably want to do each benchmark 5-10 times and average the results.

I picked "real world" apps with the exception of superpi in that thread since I don't just run synthetic benchmarks on my machine Please let us know what you end up finding if you do the experiment.

 

[dealmaster00]

Wow, that was an incredible read, thanks so much for taking the time OP!!!

 

[ALECUBA]

how bout the multiplier?? 8x400(actual) or should i reduce that to make it faster or something?

 

[adairusmc]

Excellent guide :thumbsup:

 

[graysky]

@alecuba - read the last section of the guide where I talk about the lack of difference between different multiplier/FSB settings...

I'm getting a Q6600 in a week and will definately refer to this. Thanks, Op!

should it be stickied ?

we are getting a LOT of threads on OC'ing ... and it appears that the OP has put a lot of work into it including updating it

I think it should be. This guide sure did help me get my current overclock, and was easy to follow.

 

[AceFan84]

This is a really great guide. I am building my first pc and will be receiving a G0 stepping Q6600 soon. I plan to try to OC it to around 3.0 Ghz with air cooling. This guide will be a big help to me so thanks for taking the time to make it up.

 

[apoppin]

OK, it is 'stickied' for 30 days
-ask again in a month if it needs more permanent status.

Please point new topic posters to this thread to help eliminated the unnecessary clutter of duplicated questions in CPU forum.

 

[mrblotto]

Great read graysky! Presented in a clear, step-by-step manner. The only way I think it could have been done better is if you included sock puppets....lol!

I'm curious to know why:
".....**nForce590/570 Intel Edition based motherboard will not work with this guide nor recommended for overclocking**"
Of course, I have an ASUS P5N32-SLI, which has the nForce 590 chipset (I shoulda stuck with Abit con sarn it). Just curious, that's all.

I vote for stickiness.

Great Guide ill be using it very soon, Just one question, You say to run two Orthos for the 4 cores of your CPU so if you have a Dualcore- I should run just one Orthos and set the affinity to Cpu 0 and Cpu 1 correct?
