Overclocking GPU and RAM...

Can someone give me a crash course on where to start to do the above please? I know the information will be on the forum somewhere, though its finding the right information that's the hard bit! :(Prime95 has been on for the last hour and the temps are sticking round about 73'C being the highest to 66'C being the lowest. 3.01GHz (430*7) Is this about right before going onto overclocking the other components or is it a little high??

Just on another note, i installed an extra fan shown on this pic, its the one bolted to the support and is angled slightly (This is just a image i found online). For some reason it doesn't want to spin!?! :confused: I had the side of the case off the other day and i just nudged the fan and it got going, though since booting up it's never turned on...
 
As it is at the moment i've left the DRAM and GPU at Auto, is this likely to cause problems with the CPU running at a faster clock speed? I've also lowered the Vcore to 1.3v, not much difference to 1.4v IMO.

Also when i'm running CPU-Z on idle is seems to jump between x6 and x7, though when on full load it jumps to x7 and stays there. Is a stable overclocked pc meant to stay on the multiplier you set it to?
 
That's known as speed step, and will be because you have speed step and C1E enabled in the BIOS.

Generally most overclockers turn them off, as it can cause problems jumping from frequencies so often.

Regarding RAM, check CPU-Z to see what speed it is currently running at. If its DDR2800, then it should be at 400mhz or so, DDR21066 at 533. Slightly older RAM can run slow than this. If it is already over clocked, it will be higher than the speed it can run at, but this depends on your CPU-RAM Ratios and how they are set.

Post a few screenshots of CPU, memory and SPD tabs of CPU-Z, and also more details on your BIOS settings.

Here's the screenshots you were after mate, i think thats everything. I'm very new to all of this pc business never mind overclocking! :p If you could possibly go through some things you might think i need to change, that'd be great. Is turning off speed step and C1E recommended in my case then? I'm not a hardcore overclocker or pc gamer. Just generally play the odd game, browse internet and download media every now and again.

I'd definitely set your dram voltage manually and to its max voltage as stated on the memory itself (usually). Also disable both spread spectrums. The rest you can tweak if you run into stability issues. I try and set as many things manually now as i can so i know exactly whats going on and whats probably causing the problem if i have issues.

How can i find out what this needs to be? And be spread spectrums, do you mean speed step and C1E? Like i said i'm clueless about most things in the BIOS and this is the first time i've played with figures etc...
 
on the side of the ram it will have a sticker and tell you what voltage it needs and timings, prob something like 2.1v and 5-5-5-15. go into your bios and set this. should be dram voltage and first 4 sets of timings for your ram

at the moment your ram is running at 860mhz.you need to change the fsb strap, doing this will show different figures for the ram speed in bios. should haver options like 233,266,333,400 there

under cpu configuration you will see c1e,eist, speedstep and twp other options ending in spectrum, disable them.

gpu you o'clock via the drivers for it
