I thought I should give it a go and see what I can squeeze out of my current system.

I would be most grateful if someone who knows more than me about overclocking to review my current rig and settings (If you require any more info, please let me know).

CPU CLOCK RATIO [8]
CPU HOST FREQUENCY [400]
DRAM TIMING [5-5-5-15]

SYSTEM MEMORY MULTIPLIER [2.50x]
DDR2 OVERVOLTAGE CONTROL [+0.40]
CPU OVERVOLTAGE CONTROL [1.375V]

Any chance of increasing the image size? Can't make it out :)

Look up the rated timings of the Geil memory - 5-5-5-15 isn't that great (doesnt make a huge performance leap but every little helps :p) - also +0.4v is quite high voltage.

Thats the best I can get it, hope it helps and is more viewable.
 
Thats better :)

Right, the OC looks so far so good. Have you bench tested it at 3.2GHz yet? Take a look here for stress testing / temp monitoring apps - http://forums.overclockers.co.uk/showthread.php?t=17757620. You may find 3.2GHz being the sweet spot, especially with that voltage.

Having 4GB you may find the memory will not overclock much past stock, see how it goes though.

What voltage would you recommend instead of the +0.40

Well you are putting 2.2v into the memory, which is probably rated 1.9-2.1v, so it maybe safe to drop it back to +0.2 or +0.3. If you have the exact model or details of the memory, it would give us more info :)

I have 2x "GeIL 2GB (2x1GB) PC2-6400 CAS4 800MHz Ultra Low Latency DDR2 Dual Channel Kits (GX22GB6400UDC)".

As you can see I have 2 of these kits installed, thanking you for your help.
 
The ram timings on that are 4-4-4-12 & you are running them at 5-5-5-15. You may as well leave them on that though, as it will overclock with the looser timings :)

Make sure 3.2GHz is stable, then nudge the vcore up a little and continue OCing.
 
I appreciate all your help so far and I am really enjoying overclocking my rig and I am supprised at the savings of this and some of the results you all achieve here. :)

How much would you advise to increase the settings each time of each overclock?
 
I would go to the x9 multiplier as you're going to have the memory coming into play on the x8 multiplier.

Up the CPU Overvoltage by 0.025v, and then up the FSB (CPU Host Freq) in 100mhz steps til you need to up the CPU voltage again.

Download CoreTemp for reading temps too.

Many thanks all, i'll keep you posted on my achievments and I hope you don't mind me coming back to this post if I require more help.

Many thanks :)
 
Also drop your FSB to 360mhz when you go to the x9 multiplier, and start from there.
 
Many thanks :)

Is it normal for CoreTemp to state the CPU is at 3600MHz (450.00x8.0)?

I've read that Vista shows this incorrectly along with many other programs. So, can I assume the same problem exists here?
 
Yeah dropping the multiplier confuses a lot of software. CPU-Z will always remain correct.
 
Should I leave the memory timings at 5-5-5-15 or can these be changed now that I'm using the x9 multiplier? Also is it okay to up the CPU overvoltage to 1.625 as that would be the total if I upped it by 0.25? I think I have that correct.

Oooops that was a typo. Should have been 0.025v :o


And you can leave the memory timings until you've finished clocking the CPU.
 
Just wanted to verify a few things;

My CPU is running at 3600.0MHz with temps at 51 degrees/c @Idle.

I changed the Multiplier to x9 and left the CPU Host frequency at 400

I set the CPU Voltage to 1.4000v

CPU-Z shows Core Voltage as 1.360V?

I wanted to double check as it seems quite a big jump from 3.2 to 3.6 and am not sure if 3.6 on air is a good idea or not.

What temps should I be safe with at idle and what temps should be safe to goto on both idle and load?

Should I lower the CPU Host frequency, or just stress test as it is?

Sorry to sound like a noob but I am :(

Many thanks for all your help and patience
