***The Official E4300 Overclocking Thread***

It's not that I doubt you, but that's quite a big change in the world of overclocking. How much info is there on this? Does it still help if you run them partially in sync, like 4:5? Or do you just aim to get them both as high as possible for the best result? This is as big a step as when PCI bus speeds got fixed (nforce2 ?).

Just read a couple of Asus P5e-sli reviews, they all detail that the bios options are linked/unlinked (1:1 or not); after that there is a separate option to run a divider but also you can select memory and cpu bus speed independantly. That is the new thing and really its just like Nforce 4 having a locked PCi bus so that u didnt get data corruption while upping the FSB.

Good stuff, roughly what vCore?

1.55v that was with my old 6600.

The quad is a different story....

I'm hoping that these will run cooler due to not having the extra cache disbabled but just having 2mb.

Of course I have bought one for fun at this price point to overclock.
So we will just have to wait and see.

Ive actually read in 1 review and on xxtremesystems.org forums that the running 1:1 at high speeds doesnt work as well as with the 680i and that it needs a bios revision to sort it. Maybe just near 500Mhz though...

It's absolutely true that it will not run at 1000MHz. But it will run at 1004 or 1008. The asyncronous RAM speed is not truly aynchronous, it recalculates the divider at reboot and applies it, but given that it is allowing 0.25FSB step increments it is probably to be expected that some combinations are going to be a bit flakey.

Also about that thing I said with the 8800 needing 2 x 16 pci-e slots, read that directly from the description on OcUK sales page; but it is contradicted in a few reviews Ive read ect. Doesnt concern me however, as I "only" have a single x1900xt. :)

Absolutely - It's been shown to be wrong, but they still have it up there for some reason.

I agree, it is quite a big jump in thinking from the fixed 1:1 or better ratio's of the P965 boards.

It's also probably not as clever as I made out. It's actually always been a afeature of NVidia chipsets since NForce 4. What happens is that you dial in the RAM and CPU speeds you want and it does a quick calculation based on dividers that run in quite fine segments and it then adjusts the RAM speed down by a upto 9MHz to get the divider right. It works very, very well and it's very stable. It's not new though. Because it shares the same C55 Northbridge with the 680i, the 680i boards do this as well.
 
So, still nothing on overclocking the e4300 by someone here?

I just got:

* Team Elite 2GB (2 x 1GB) DDR2 PC2-6400C5 800MHz Dual Channel Kit (£152.74)

* Intel Core 2 DUO E4300 "LGA775 Allendale" 1.80GHz (800FSB) (£115.14)

* Gigabyte GA_965P_DS3 (Socket 775) PCI-Express DDR2 Motherboard (£82.24)

* Antec Nine Hundred Ultimate Gaming case (£70.49)

* Arctic Cooling Freezer 7 Pro CPU Cooler (Socket 775) (£16.44)

I got the cheaper memory because I was under the impression that due to the e4300's 200fsb and 9x multiplier the system wouldn't be as reliant on uber memory. I just note a couple of threads here where people are still talking about dominator kits etc... Isn't the point of these chips that they are slightly cheaper than e6300's, but, more importantly, they don't need the expensive bits (memory, mobo) to go with them and this is where the real saving is? Why buy expensive memory and then skimp on a few pounds and get a e4300? Am I missing something?

Cheers

No - you're not missing anything - the kit you have bought will stand you in good stead. I think what is being said is simply that in any system, faster RAM is always a good thing.

With your RAM and the DS3 you can run almost 3.8GHz without overclocking the RAM at all. Where better RAM might help you is if the 9x multiplier turns out to be a hindrance rather than a help and the better overclocks come at the 7x or 8x multipliers - then you could could be left a bit short if your RAM won't clock to 3.5GHz, but I doubt it.

My advice would be stop worrying and get the system built. Get a moderate overclock on it and burn it in. Then, once everything has settled down, clock the living daylights out of it ;)

Cheers, I've stopped worrying.

The gear should be with me on Thursday, so I'll put it all together and post some results. I'll bench it at stock then overclocked and post the results. Which programs would be best to benchmark? I've got 3dmark 3, 5 and 6 but are there any others I should be using (I keep seeing Prime and Othos?)?

Cheers

Sisoft Sandra 2007, PCmarks, SuperPi...etc are all good performance indicators.

Orthos is based on Prime95 but designed solely for stress testing purpose.

the reason why i went for the dominator is to be future proof, this cpu only cost me £100 so i can sell it in a years time make hardly any loss on it and buy a quad core for dirt cheap, simple really

Gotcha. I was coming at it from a strapped-for-cash angle.
 
what do you guys think would be the better overclock?

a multiplier of 7 and 500fsb = 3.5ghz

or

a multiplier of 9 and 400fsb = 3.6ghz

i know the second has 100 mhz higher clock but the other has affectively 200 mhz faster memory so i might test both in 3d mark and see what the results are, my kit should be hopefully arriving tomorrow, people have always debated that the 100 mhz clock speed is better but it might be different for this chip due to smaller cache, etc

Basically MHz>*

At the same MHz then the higher FSB would be better.

im talking about the asus p5ne-sli

The northbridge is kept cool by a passive heatsink

what would be the best way to put a fan onto this and can i buy it from OCUK?

That's not half bad though, when you see the MCP chipset doesn't even have a heatsink at all! I can assure you though, that even during heavy overclocking this does not seem to get -that- hot. I still have my fingers to prove it. However, a heatsink would have been a nice addition. If you plan to do a lot of overclocking, pointing an 80mm fan towards it may be the smart thing to do. Or purchase a $5 chipset sink

what is the best way to cool this? can i buy it from ocuk?

my order will be getting shipped soon so please could i get quick answers thanks for your help
