yes, 300 (cpu fsb) x 9 (multiplier of e4300's and e6600's) = 2700

Can I just say a big thanks for this Clunk

I'm no newbie to OC but I haven't done C2D yet and was thinking of doing so later in the year and this is an excellent intro

[Areku]

Clunk have just been having a read through this and it looks great. Ill be trying most of this stuff out when I finally have the other parts for my new system.

Great work!

[mosherben]

I could do a cover on Abit AB9 Pro if anyone is interested, but basicly it's the same steps as Clunks. Havn't disabled any of the features and my CPU is at 3.2 That is, however with a E4300

[Mike Fishcake]

Cheers for this! Just what I needed.

Thanks Clunk, nice and easy guide to follow

One question - what sort of temps are 'too high' for the C2D? I'd be watercooling in any case but i'd be interested to know. Do 939 waterblocks fit C2D (well you never know) on the whole?

Even if your motherboard and RAM arent affected, just do it anyway, get into the habit .

So, we have set the RAM to 533 and the FSB is already at 266. Lets up the FSB a bit. Change it to 300,

Tried reload image in Opera and with firefox same problem.

Are they still black squares? Should be bios shots, but they are hosted on photobucket, maybe I should find better hosting

Some 667 ram will clock right up, but thats for another guide really. Without clocking the ram, you are looking at around 3ghz with a cpu thata has a 9x multiplier.

If you can do some bios screenshots of the part that shows where you change the fsb, the ram timings and the cpu settings, I'll add them. I want to keep 680i seperate for now as they are slightly different.

Thats one of those questions that noone can answer. You need to think about room temp, cpu temp, is there going to be a GPU and a NB block in the loop, are the rad, pump and blocks up to the heatload etc.

I've also found that each different C2Dthat I have used, has had vastly differing temps at the same voltage. This is why I mentioned about using a couple of different software temp monitors (or more), and take an average. I prefer to keep under 50c, under load, or less if possible.

Thats a class article Clunk, just what I needed to read!
Thanks!

I meant more generally - as in "when does my computer's brain melt?". 50C is about my max comfort on 939/X2 right now, typical is about 35C at this time of year, rising to 43C max during the murderous summer (very hot upstairs room). It sounds like i'll see much the same on the new platform, that is until I add a super-hot graphics card perhaps.

My setup would be much as it is now - double rad (2x120mm), 10mm tubing, cpu->nb->graphics->rad->pump - which copes well with my current heat load.

Nicely done Clunk.

I think 75c is the safe limit when C2Ds start throttling, but for every day use, you dont really want to go there

Meh, 75C is for girly CPU's - remember the manly P4's ?

[Clunk]

Added a bit of simple troubleshooting

[mallett]

is there any performance differences of decreasing the memory divider but upping the fsb and therefore keeping the memory at its rated frequency but upping the cpu clock? or is this just pointless?
