Hi folks - been reading all the excellent advice on the board but as this is my first time overclocking I thought I'd check with you all first

I've bought and installed the following:

E8400
Abit IP35 Pro
4Gb (4 x 1Gb) OCZ Platinum 6400 DDR2 RAM

Sat in the Antec 900 case OCUK like to sell all their p.c.'s in. I've added the side panel fan to help cool the 8800GTX (and cpu as an aside). 600 WATT brand name PSU

Core Temp shows the CPU running at approx 40C on both cores, so the stock cooler is going... no surprise there. CPU-Z shows 1.140 Volts on the CPU

I had issues with getting anything working at all first until it dawned upon me that the auto settings on the RAM set the voltage to 1.8v!! Upped to 1.9 and all is working fine now.

I upgraded the BIOS to v16 beta in an attempt to fix the start up issues and it's running fine. :cool:

What I'd like is to have the E8400 running at 4GHz (ideally) and I've read through the beginners guide (well written and thanks), so I know I need to up the voltages on the CPU and memory then start stepping up the FSB speed... oh and loosen the timings on the memory (5-5-5-15 I think someone said. I have it set manually to 4-4-4-15 at the moment)

So do I set the voltage on the core to 1.3V ish and the memory to 2.0V and go from there? :confused:

Could someone recommend a cooler from OCUK (I'm 20 minutes from the shop) and possibly just say - "set the BIOS to:" and save me some time ;)

Thanks folks - I have looked for a similar post but you guys know the details of OC'ing and while I am PC techie (security & Server side) the black art of overclocking has been an unknown to me :D (so quite a lot that is said assumes a fair degree of previous knowledge)
 
you will need to set the memory voltage to 2.1 as that is stock on that memory, you will also need to set the timings to 4-4-4-12 as it will be running at 5-5-5-18 by default, a good cooler would be the Thermalright Ultra 120 or Tuniq Tower, i have the Ultra 120 and im running my Q6600 at 3.8GHz fully stable, firstly you will need to set the memory divider to 1:1, then set the FSB to 400, increase the cpu voltage to about 1.375 which should be enough with an E8400, run orthos for about an hour at first, if it fails, you might need to increase the chipset voltage a bit as you are using 4 sticks of ram, if it still fails, increase the cpu voltage a bit more. once you get 400 x 9 stable, increase by about 10 fsb at a time until it becomes unstable, then go back to voltages until it is stable, do this until you cant get any more out of the chip, keep an eye on temps as they will be the limiting factor while on air cooling
 
Raiderx - thanks very much... an excellent summary to follow and cheers for taking the time!

I'll get the cooler you've suggested on Saturday and go from there.... bus speed is presently set to 334 x 9 so the first jump will be a biggie methinks...

wish me luck!
 
Sorry chap. NB = Northbridge. It's where the memory controller resides.

I think that 1.45v is about right.
 
I picked up the Tuniq 120 tower. Oh bugger it's a rebuild job. Arse. :(

Oh well - I did need to replumb some of the wiring after putting in the IP35. I just hope this behemoth of a Heatsink fits in the Antec 900 next to the 8800GTX.... could be tight in there!

Thanks for all the help folks - much appreciated!
 
Pretty well thanks for asking - I've managed 3.8GHz and rock stable.... got an issue with the fan on the Tuniq - it keeps coming on and going off seemingly randomly at the moment.

I think I have put too much paste on the heatsink as it runs at 48-50C under load, and it may be that causing the fan to keep kicking in.

I'll post my settings this evening and let people critique them.

I was pleased to see that I was able to run superPi for 1M places in 12 seconds... a very fast processor!


<edit>
I've just found a good guide article and have realised I have put way too much paste on.... yeesh... time to get the board out again

is the guide... very simple, very clear.
