Help overclocking E1400

Ducky Spud · 3 Mar 2009 at 23:21

I know its a useless processor for games, the L2 cache is tiny etc etc, its hopefully just filling a gap until I can afford somthing a little better.

Anyway, Im not completely new to overclocking and I know this processor is capable of more, I just cant get there and am not sure why! The photos show my current settings. Ive basically increased fsb to 300, upped the vcore (its over 1.5 on this but boots at 3Ghz with about 1.47) and set the "system memory multiplier" manually. Also changed the voltages slightly for the DRAM and MCH (northbridge right?).

Ive also disabled some of the settings in here

Most guides say about setting the RAM divider, guessing thats the same as my memory multiplier? Just worked out differently? I can get mine to set my RAM frequency to just over 900 before it becomes unstable.

Also, Ive read about setting the NB strap, is that "MCH frequency latch" on mine? Ive heard that I should set it as high as I can (over 1000 I was told) but the highest setting for it is 400Mhz at which point my PC wont boot anyway.

Anyway, you can see my settings as they are. If I raise the fsb even by 5Mhz it wont boot, even when I raise my vcore upto around 1.54 (like I said, it boots as it is at about 1.47). This makes me think it must be some other settings? Or have I just reached the limit for this chip? Hope not as Ive seen quite a few running 3.4/3.5Ghz

Thanks for any help

Sorry for the bump, but nobody got any ideas on this?

Ducky Spud · 4 Mar 2009 at 22:30

There you go

Ducky Spud · 4 Mar 2009 at 22:55

Sorry, this better for you? Barely all fit onto my screen haha

Ducky Spud · 4 Mar 2009 at 22:58

Wait, just looked at that example, do you want it at 100% load? If so I'll just edit my last post

Hey

Screen of it running all on auto

And Screen of it running at 2.66Ghz. Just as a note, with my FSB Latch and FSB set to 266MHz, it set my memory to 1066Mhz and failed to boot. I had to manually set my mutiplier to 3.00A (set it back to 800MHz and A because thats for 266FSB... I think).

Same happened when I just changed the FSB to 266, RAM set itself to 1066MHz. Goes through the startup but BSOD's just befor it shows the desktop. Think its just my RAM holding it back doing this.

That all alright?

I did them all together, Ill try doing them 1 at a time and see how it goes. Just at uni at the moment, will try it when I get home in a few hours.

I set everything to auto including vCore, it boots and runs stable at 2.66Ghz on standard voltage. Is the MCH Core the Northbridge voltage in my BIOS? I'll have a go trying those settings when I get home as well.

Thanks for the help again

Right, I tried setting them to 266 one at a time, but when I raise the FSB the memory frequency just goes up at the same time, can see it changing as I increase the FSB

As for changing the multipliers, tried them, all booted fine and ran stability tests (only for 10mins each), all with vcore and all other voltages still set to auto.

Here is a shot while at 6x Multiplier

Is this done right? With the FSB still set to 266MHz?

Hope this helps in some way!

Ducky Spud · 5 Mar 2009 at 18:46

Yea, will try some of these. Never tried lowering the multiplier and increasing the FSB lots, might make a difference.

What about CPU Termination and PLL? Ive no idea what these do at all haha. I'll just nock them up 1 or 2 steps so its not too much and test

Thanks for the help, im off to get some tests in!

Ducky Spud · 5 Mar 2009 at 19:41

Well Ive tested a few things. Using 9x multiplier didnt achieve much more. 8x managed to get into windows at 3.15, ran a simple benchmark fine then tested with prime95. core 1 failed after about 10 seconds and BSOD about another 30 seconds after that. Upped the voltages a bit and managed to get it to last about 30 seconds before core 1 failed, so still not much better.

I'll just keep messing round, see if adjusting voltages more will improve the stability.

And I know the RAM isnt the best, but the only other RAM I have is 4 old sticks of DDR, not going to help much I dont think!!

Like I said, will keep messing round, see if I can get it running a bit more stable on a lower multiplier

Ducky Spud · 5 Mar 2009 at 21:07

Yea, when it wasnt even getting to POST it was quite annoying! Got it now on 356fsb and 9x multiplier making it just over 3.2GHz, not the most stable prime95 wise but boots to windows and can cope with most tasks so far.

On prime95 core1 fails after about 5 minutes. Not the best but like you said, got a lot to work with yet! Do you think there is a reson core1 seems to always be failing first? Or will it just be that its just the random factor of some overclocking better than others and for some strange reason my cores being different?

Well thanks for all your help

Definately doing a bit better now than I was before! Good luck with the E5200! Let me know how it goes

The FSB-strap was set to 333MHz when running at 3.2Ghz, seemed to cope fine. Can get some screens for you later if you like when I get home?

I'll try increasing the vcore as well. When I test with small FFTs it runs at about 51-52C, not too hot to cause crashes. Was running stable at over 60C before I got round to do proper cable managment to improved air flow. Should be getting some of my mates spare watercooling parts soon too which might help a bit

Thanks
