First overclock - some questions

Overclocking questions

Recently bought the E2180, with a Gigabyte p35-ds3l, and the OCZ 2GB (2x1GB) PC2-6400C4.

I've never even looked at overclocking before, but, I've jumped in and attempted it.

I put the FSB to 280, multiplier 10, which I think means its at 2.8ghz and just left the voltage as the default - and it seems to work fine through this Orthos programme.

Next up I fiddled with the memory settings - for which the multiplier or whatever its called is set to 3. Which puts the memory at 840mhz. I also set the timings to 4-4-4-15 and the voltage to +0.2.

Oh and temperatures for CPU under load are 47, is this ok?

Am I right in thinking I should reduce the CPU multiplier and try to get a larger FSB, meaining the memory multiplier would be a lower number?

Thanks

if you can make it to 4-4-4-12 with 840mhz then that would be perfect.
Anyways, good chip you got there if it does 2.8 on stock volts

it will be slightly faster if you used 333 x 9 instead of 300 x 10
idle temps are fine,what cooler you got on your cpu?

Arctic Cooling Freezer 7 Pro

I've only got it at 280x10, not 300... I haven't gone as far as 300 yet..

Can I reduce the timings for the memory then? I just put in what the description page said.

Is stock volts for the CPU just what the bios sets it to? I think its set to 1.325.

47 is the load temps, not idle, think it idles at around 27.

And fans are set to low (Antec 300 case), should I put them to medium/high?

In general, i always clock with slack timmings, so something like 5-5-5-15. This rules out memory related bottlenecks when trying to find a CPU's limit.

I'm not planning on pushing this to the limit, just an amount that is high, but not going to cause me any problems whatsoever.

Any more insights on this? I don't really know what I'm doing, so any comments are appreciated.

Do I need to increase any of the other voltages? There's one called (G)MCH?

If I put more memory in - result being 4x1gb, do I need to change anything?

The MCH is the north bridge, i would advise icreasing it +.1 when overclocking or using 4 sticks of ram.

That processor is capable of much more than 2.8ghz, go for 3ghz and drop the memory multi to X 2.

You may need to increase the voltage to the cpu a bit for 3ghz stable but you could try it at current voltage (assuming it's stock) and go for an eight hour orthos stability test.

Also put the memory timings back to 4-4-4-12

Wouldn't let me run at 300x10, so upped the voltage and got it working once voltage hit 1.4. CPU-Z says core voltage is 1.344 though???

Idles at 30, load at 52...

Think 3ghz will do me now, gonna start playing with the memory.

I put MCH to +0.1V as per the earlier message, do I need to put FSB voltage up at all?

Garyj881 · 14 Jul 2008 at 20:06

Put it to +0.1v also.

From there if you're happy with the temps try more on the same voltage

aspirins · 14 Jul 2008 at 22:13

Ok, had to put voltage up a bit more - 1.42 in BIOS, but CPU-Z says Core Voltage is 1.376, I don't understand this.

This is at 300 x 10, and the memory multiplier thing is at 3 or 2:3 - this makes the memory 900mhz. It's only 800mhz memory, is this a problem?

Also, I put the timings to 4-4-4-12.. is this ok too?

Running a blend test at the moment, seems ok so far though..

PhoenixUK · 15 Jul 2008 at 00:03

I don't think it will run 900mhz with 4-4-4-12, if it does you got a great pair of sticks.

You can try setting the memory multiplier to 2.40 which will put it at 720mhz and setting the timings to 3-3-3-10.
