Hi all,

I have built my system:

Conroe E6600 Core Duo processor
BFG 8800 GFX card
EVGA 680i MB
GeIL 2GB PC2-6400 CAS4 Dual Channel Kit 2x 1Gb ram
2 x 200Gb Raptors in Raid 0
Sythe Ninja cooler - had to modify the thing to get it to seat ok.

In my warm computer room idle temps vary between 35 to 38. If I run Intel TAT and work processors temps go to 60.

I know I need to get my FSB up, but am confused on this motherboard as the Quad FSB is at 1066.

Also When I have tried raising this and saving BIOS, when the PC re-boots I get a long BEEEEEEP and eventually the PC reboots but with stock settings. I am therefore guessing the overclock failed and the PC used default settings.

So i have tried upping the FSB and leaving my multiplier on 9, but when should I add more voltage and to what?

How do I know why the overclocking failed.

Can anyone who has a similar setup to me help me out, I really want to try and hit 3.5 or 3.6

Incidentally I tried Ntune and it worked by upping the PCI speed to 3025 and it also changed the memory speeds to 4-4-4-12. Funnily enough the FSB I think went from 297 to 397 - but that is from memory.

Please I would appreciate some of your expert knowledge !!

Regards
Ian
 
The long beep is 'overclock failed' it will then revert to default settings. You will need to add some more cpu vcore in small increments until it becomes stable.
 
hey guys thax to you I have managed an overclock.

Currently running at 3.3 after uping the quad FSB.

However, I cannot get the memory FSB any higher than 810 otherwise I get boot issues or stability.

Also managed to overclock at first and didnt realise auto voltage was on - damm those temps were scary !!!

I have changed my memory to 4-4-4-12 2t, and at 3.3 I can boot and run windows etc, however it did crash after using Flight sim X for 30 minutes.

Questions - can I push the memory FSB any higher?
Should I mess with the voltages and further?
What should I be running to prove stability?

Thanks
Ian
 
What voltages are you running at the moment?

Put your cpu voltage to 1.46875v (1.4v actual)

Put memory voltage to 2.1v


Run prime 95 for stability at first, If you pass this for at least 4 hrs you should be stable enough for most games and cpu intensive programs.

If you want to make sure your 100% stable run orthos(sp2004) this is the same as prime 95 except it runs 2 instances of prime 95, One on each core.

Maybe to get past 810Mhz you have to increase the memory voltage more or reduce the timings to say 5-5-5-15?

Maybe try reducing the 5X multi to 4X?

At the moment i'm happy with my 366 x 9 @ 1.4v. I will tinker with it a little more later on though.
