EP43-DS3 overclocking and SLi
« on: May 23, 2009, 11:14:07 pm »
Hi,

Just bought my new pc, it has this motherboard with a Q6600 processor.

I want to take the processor to 3ghz but its been a while since ive done any oc'ing.

Can someone advice me how to do this? should i use easytune or bios?

Also, i couldnt find an SLi brige in the box for the mobo, am i to assume that this board doesnt require one?

Thanks in advance

Dave.

When OCing you just raise bus speed to 333 MHz reduce memory multiplier depending on which memory you have, and set voltages on normal (my E6320 ran 3.72GHz on this board with stock voltage). It should work that way.

This motherboar doesn't support SLi, because P45 doesn't support it.

Hi, this is my spec, could you advise further? thanks

memory 4 x

 Memory slot
Installed Enabled Size 2.00 GB 
Form Factor DIMM
Frequency 800.0 MHz 
Slot A0 [Bank0/1]
Manufacturer 
Type 
Type Details - 
Enabled Size 2.00 GB 
Total Bit Width 64 b
Data Bit Width 64 b
 
So there is NO way it will ever run SLI on this motherboard? the guy who built it has assured me it will.

Thanks

David

So you simply set the FSB to 333 MHz and memory multiplier to 2.40B (if it is not B then use the one for the 333MHz FSB) and it will run smoothly.

P45 only supports crossfire, no SLi. Only Intel chipset that supports SLi is X58 which is unfortunately only for i7.

So he's basically lied to me.

Not happy at all about that!

I'll hold off oc'ing for now as i'll want to return this pc.

Thanks for your help mate, appreciate it :D

ok so im keeping it for now.

so chupo, for me to up the cpu to 3ghz are these the only amendments i need to make? fsb and memory multiplier?

Most likely yes, if it doesn't work set voltage to "auto", and it should work right.

If you ever want sli you will need a dual gpu card for that motherboard (2 gpu's, one card).

CPU voltage, I wouldn't leave auto but try 1.36V that should be plenty. It is a G0 stepping? Get cpu-z and check that, if the multiplier in it says 6x and about 1.6Ghz clockspeed, just ignore that it is just intel speedstep to save power, it will run 2.4Ghz stock once loaded, same will go for 3Ghz.
I would run prime95 or OCCT for about 1 hour to test stability minimum, 4 hours or more is generally better and will tell you if it is really stable. So try that and post back, if it doesn't work don't worry there are plenty of things which can help.

thanks, i have to admit i had a quick look and didnt feel confident doing it myself.

the last computer i clocked i had step by step instructions.

Is there anywhere on the net i can get them in this instance?

thanks

Dave

Think I did it. Changed all as advised. The voltage increase, is it the vcore? That the one I upped, it boots and runs on 3d mark vantage.

How do I monitor temps and test for stability?

Thanks

Ok did a quick test on occt and under load the temp hit 71c so I ended the tests as I think it would have kept going. Do I lower volts slowly?

Lower the voltage until it crashes in the test, then return it to the last stable one and that's it.

What temp is acceptable under full load?

I don't want to fry it.

Increased voltage slightly and re ran tests for 10 minutes on OCCT.

Ran with no errors and temps peaked at 70c on core 1, 69c on core 2, 66c on core 3 and 67c on core 4.

Idle temp 40 40 34 39

This acceptable?

I dont imagine many instances when all 4 cores will be under 100% load?

Lower the voltage instead of increasing it, and then try the stability tests.

PS. Everything under 70 degrees is fine.
