C2D Overclocking Guide for Beginners

[john317]

It may well be possible! The only thing you can do is try. You should only increase your voltage if you need to, dont just increase it before trying it. My Q6600 does 3Ghz on stock volts, no problems.

I think i will give it a try especially with Clunk's awesome guide

I bought Socket 775 mobo and some Geil RAM for cheap and added a E2200 CPU for £50 about 3 months ago, cooled by a Scythe Ninja with 120mm fan and clock to 3GHz 24/7 and 3.44GHz for benchmarking, I think the low C2Ds are great value for money.

nice what voltages did you need?

[Ben Rogers]

1.35v for 3.0GHz but I used 1.55v to benchmark it at 3443MHz. I havent played around with this setup I must admit as I use it for actually doing meaningful things on sometimes and want it to be rock solid stable, but when I first got it the aforementioned clock was the highest it would benchmark at with 1.55v - might do same speed on lower for benchmarking - I will try sometime.

A few problems i have ran into here, lowest vcore setting on the mobo is 1.325, seems high for the lowest setting? Its currently at 1.345 but cpuz is never reading it higher than 1.310~ not really sure what this means in terms of voltage limits and upping it some more.

Also there is vcore and vtt, both seem to relate to the cpu, havent touched Vtt, should I leave it that way?

guys what would i need to change to get my ram running at 1:1 ?

[moogle]

you'd need to change your divider to 1:1
but then it'd run at lower speeds. why not have your cpu at 3.6ghz? then 1:1 would be fine and you should also set your timings in bios. its quite high for ddr2.

[Chunter]

my ram is 6.6.6.18 thats what its supposed to run at,what would i change to get either to run at 3.6 or to get my ram at 1:1 ?

plz bear with me ,totally new to what the words all mean and do.

[moogle]

you'd have to overclock your cpu, hence what this guide is about. but if you dont want to overclock your cpu, you'd have to change the fsb to 400 (which is 800 in ddr terms ie your ram speed) but then you'd have to lock your multiplier at 7 by which you'd lose 200mhz on the cpu speed, or if you wanted run it at x8 with a speed of 3200 (a mild overclock)

But those chips can easily do 3.6 from what alot of users have it running at on XS. If you don't want to mess with your cpu speed then you don't need to have a 1:1 ratio. As long as your ram and cpu are running fine its okay.

I thought your ram was 5-6-6-18 as in cpu-z it's showing the profiles set on the ram.

damn you're right,just noticed that 5 myself.whys that i wonder ?, i set them then rebooted,shoulda saved.will look again tonight when at home.either i didn't set the first 6 or it didn't like it.remind me never to take screenshots late at night.
when i set my fsb to 400 last night my bios "projected" that the ram would run at 840.
this stuff is confusing the hell out of me.slowly slowly catchy monkey with this overclocking stuff methinks.

[moogle]

your ram should be 800 if you have 1:1 on 400 fsb.
if you'd like to overclock your cpu then say so and I'll try and help. then you can run your cpu at 3.6ghz and have a 1:1 ratio for ram/fsb.

[Chunter]

yes i'd very much like help.

Before you overclock what heatsink are you using?

[Chunter]

zalman cnps 9500 led with arctic silver 5,8800 gt with zalman vf1000,thermaltake kandalf with just the front and back 120 fans on. have just ordered a HR 05 sli for my southbridge.
i'm not new to pc's but just very very new in the black art of overclocking.

[moogle]

well thats good,
I thought you had a stock hsf on

Do remember there are risks in overclocking, but I'm not gonna be telling you to set the voltages at mad settings though.

You should download CPU-Z, Prime95 and CoreTemp. I use Everest too as it shows the overall CPU temp as the cores are always hotter. I'll find some download links for you.

[Chunter]

got them already,may just have to find what disc everest is on.also have realtemp.
