E6600 Overclock Help - First OC

Last response: in Overclocking

Hi,
I want to get my FSB to 400mhz so its in sync with my ram.
As the multiplier is locked that would mean i would get 3.5ghz dual core.

I first aimed for 3.0ghz as I've never overclocked before. I got 333x9 at 1.2750 Volts running stably.

I then tried to get 3.6ghz with 400x9, i tried this at many different voltages up to 1.4v, yet it failed to even display bios.

I'm currently testing 337x9 (3.4Ghz). 1.35v booted yet crashed at entering windows. 1.3750v has booted and I'm now going to test on orthos.

I don't know what to put into the other settings such as FSB Voltage & Memory Voltage and how these effect system stability.

Could someone please suggest a really good guide that will show me everything i need to know or give me any pointers. I've looked at a few sticky's but i couldn't find what i was looking for.

Thanks in Advance.

Added:

I just ran Orthos at 377 x 9 at 1.3750v and it failed after a minuet.

Help would really be appreciated.

Thanks.

I would bump it up to 1.5V just make sure your fan is NOT on auto aka disable auto fan in BIOS so it's always going full blast. If it boots then just watch your temps with core temp. Also make sure you memory timings are relaxed at least to 5-5-5-15. Also make sure you have the power saving features off such as EIST, E1T, I think thats what there called.

C1E i think it is (instead of E1T). Also, I have mine running at 400 x 9 (3.6GHz) on my Q6600 (which is just two E6600 stuck together [basically]). I have my bios set up with..:

Vdimm (RAM) +0.2V
PCI-E (Videocard) +0.2V (NOTE: If you don't need to do this DON'T [You probably don't!!])
MCH (Northbridge) +0.2V
FSB +0.3V
Vcore +1.46875V

So you have a rough guide, although you might need slightly different settings to get the same results.

Just try experimenting a little bit and see whats stable. as buildo said, loosen your ram timings to start with so that you can rule out everything failing apart from the CPU so you'll know once it's stable.

But voltage is what you need. Once i started going above 360 x 9 I needed to raise my Vcore in leaps and bounds to reach 400.

I'm going to help my friend overclock his new Q6600 G0 stepping CPU on a Foxconn X38A mobo. I have no idea how to overclock this CPU and havent even looked at the bios yet. Anybody have the same set up as he does. This is a brand new build and we are putting it together right now and want to begin overclocking.

What do I start with for software (ie prime95, cpu-z)???????

Are we just raising the voltage and FSB like on older A64s. For example I overclock my 3500+ by raising FSB from 200 MHZ to 242 MHZ or 2.2 to 2.64 and raising voltage from auto to 1.55. Is this how new CPUs like the Q6600 work?

Once again I have no idea how to overclock a new quad core and what some of the stuff you guys are talking about like 400x9 (I'm assuming that is memory... I have never messed with memory when overclocking... I've only changed FSB and voltages) so I really need some education and some pointers here.

Thanks!

400 MHZ = The FSB
X
9 = The multiplier.

In my duel core the FSB X The Multiplier gives u your overall speed.

So 400FSBX9Multiplier = 3.6GHZ.

My fsb setting is under the jumper free configuration settings of the bios.
And multiplier settings is under Cpu configuration.

As far as i understand don't go above 1.5v on the cpu. there rated at 1.6v.

Hope this helps.

It depends what RAM he's got. If he's got DDR2 PC6400 (800Mhz), you'll want to have your CPU 400Mhz x 9 (if you can) to have a 1:1 RAM:CPU ratio.

However, if you can't get it that high (you might not be able to) then you could have your CPU set to 400Mhz x 8 (which would be 3.2Ghz), but you'd still be on a 1:1 RAM:CPU ratio, which is what you want (unless you want to run asynchronusly, which probably can't/don't need/want to).

I wouldn't maybe try 533 x 7, which would be 3.73Ghz, might be a little hard to get but that'd give you the true quality of the RAM, otherwise you're going to be running it under spec and wasting your hard earned $.

Or you could try changing the ratio (not sure what kind of bios you have on the foxconn MB).

Maybe try 400 x 9 with a 2:2.5 CPU:RAM ratio (How it would look on my DS3 in the BIOS anyway) which would have your RAM running at 1000Mhz which would be as close as you'd probably be able to get it comfortably...

Trial and error is going to be your best course of action I think, try out your different options (with 1066Mhz RAM you have a lot more which is always nice). Do some stability testing and some benchmarking and with SiSoft Sandra (can't remember what it's called properly) or Everest Ultimate, or whatever you like to benchmark with and see which runs fastest / most stable for you.
