Q6600 OC Help

Keep the 'External Clock' value as it is now (356), same with the multi, and run through the 'CPU : DRAM' list untill in the brackets it says as close to "DDR3-1333" as you can get it. If in doubt, go for the value UNDER 1333, not over. That way you're not overclocking the ram at all.

Set your 'CPU Core Voltage VID' to 1.4V. Set your DDR3 Voltage to manufacturers spec. Leave everything else and see if you can boot into windows. If you can, load up CPU-Z and check that your CPU is running at 356 X 9, then load up CoreTemp and Prime95. Start prime small fft's test running. If it's not stable it's just a case of increasing the various voltages untill it is, but i don't know X48 boards or that BIOS.. So this is the bit where someone familiar with overclocking on an X48 board should chime in

OK just booted like that with speedstep off aswell and the RAM at 1.7V as per OKUK's detail about my RAM.

Running Prine95 now after 10 mins Abit Guru says my CPU is @ 54.0C and the System is at 32.0C

And it just locked up

Restarting with the same settings but the RAM settings 9-9-9-24 aswell first time it wont post mobo shows C5 "Cal chipset hook to copy BIOS back...."

One thing is should I be getting my RAM close to 1333 or 1066?

Is seems any time I touch the RAM timings I get the C5 error on the board and no POST... Im assuming im not supposed to wait a while for this? and it just means its not working?

Have you tried running the ram at its native speed without pusing the cpu, just to rule out any possible issues with the ram ?

The top post reads like " ive built new machine, occed right away and have issues"
Just wondering if all the components are fine at there normal rated speeds.

Yes its fine I played on stock all last night for 6 hours.

Components are fine just the settings are needed I think.. Iv never messed with voltages before my old Opteron was simple to OC.

OK I just retested at 1.45v
3.0Ghz FSB 333 * 9 DRAM set to DDR3 666.

I assume this means the RAM is underclocked and impossible to cause an issue. It booted then locked up in Windows..

Assuming the RAM statement is correct does this mean I simply need more volts to the CPU?

The CPU never gets hot just seems to lock windows up.

Well its currently stable at 3.3Ghz with these settings...

367*9
and RAM at 1225

I put the CPU on 1.45v and the RAM on 1.6v

It seems to work fine been playing Crysis, COD4. Done a stress test in Everest and its idle at 40C and full load about 55C

I darent turn it off now tho incase it doesnt come back on....

ok here goes!

READ THROUGH THE WHOLE REPLY FIRST.

I have this board almost exactly the same setup cept for 2 things i have ddr3 1600mhz ram and an ati 4870 gfx card and i managed to get 3.6 ghz on air 71c max temp (in coretemp)......ok....

so board setup works as follows......

frst thing u need to do is turn off ur pc then reset the cmos on the back start from scratch.... ok first thing u have to know is every cpu is diffeent and will clock at diffent speeds you have to find the sweet spot.... The balance between stabillity, voltage, temperature and speed.

so go to the cpu operating speed and make the multiplier 8 then put the clock up till u get 3.0 in the estimated new cpu clock (350Mhz i think )when u want to push this to 3.3 or in my case 3.6 you have to go up in incriments eg. 350-375-400-425-450<---(thats what im at) and at the same time u need to push up ur voltages 1.400v-1.425v-1.450-1.475 and see if it posts each time you change it also u will want to test the temps each time you boot it into windows to check if its stable so get maxcpu and coretemp and run it for 10mins-30mins if it crashes go back and push up the voltage a few incriments and i think they go up by .005 each time till u get it stable.......to start with.....

Here if u want to push the multiplier back up 2 x9 u gona have to drop the cpu clock eg for mine 450-400Mhz x9 and push up the core voltage by about .025v maybe a bit less maybe a little more depending on how hot it gets i would start at less and go slowly to more tho so again do it in incriments and make sure its stable and again these settings are individual to each core so u may not get 400-450 at all. The chip is designed to do 2.4 remember that.

Then look for the correct DRAM Speed.... set your cpu to stock and this is where it start to get a little tricky cos here u have to find the one that works for u and because u have diffent ram to me and idk if u want it over clocked 2 but mine is set up on 1:1.50B u may need to go lower than that like 1:1.50A or even 1:1.33 u will have to check what u getting next to it where it says in brackets (ddr3-1068) like in ur pic.... but start at the top and work your way down and test them all cept for the last 3 (cos i know those will be too high for your ram). now the rated voltage on ur ram is 1.6v so if it fails on that one try push ur voltage to 1.8 may even need to go to 2.0v but be careful when doing that go up from 1.6v at 0.1v a step and restart and post each time may not need to tho my ram is running at 2.0v and is rated at 1.8 you could also relax your timings if u wanted to go that way.... again id have to find out more about ur ram to know what to set it as.

Now both your cpu and ram have to be done together and if it fails u need to figure out which one failed by dropping one of them then the other eg. (450Mhz 1.4800v 1:1.50B 2.0v)<< thats fail then test Ram (425mhz 1.45v 1:1.50B 2.0v) or Test CPU (450Mhz 1.4800v 1:1.50A 1.8V) or whatever u know works on ur ram settings at that core speed and may need to increase your voltages to get it stable in windows but again watch ur temps....

another thing u need to do is go into abit eq and set all your fan speeds to max and lower all ur shut down temps to the lowest values each time u reset the cmos.

Doing all this takes time to do so make sure u got a few hours and take it easy if it doesn't post and u get an error or it crashes dont panic cos its not turning on just reset the cmos.... This board is awsome.... ive done this soooo many times so dont stress out just watch the temps. i always like my computer to have a max temp of about 70c if it gets hotter than that you gona start to have bigger issuse like melted cores and fried ram so cooling and air flow is extremely important....

and i hope that helped
