Overclocking a 6600 on a DS4 tips?

richieboy · 6 Nov 2006 at 09:02

Hi guys,

I recently got a DS4, 6600 and 2GB of Geil 6400. Everything seemed fine so yesterday i whacked the FSB upto 300, multiplier was already on the highest (9) and changed memory multiplier to 2.66, so giving me the following:

I have heard that these 6600 can do a lot more, but am not sure exactly what other settings i should be changing when i change the FSB? Im fairly new to OC'ing, and have read both the DS3/DS4 threads which have helped me get this far, have also read the OC'ing thread but it didnt help me with what options i should change when i change the FSB. I put the voltage up a bit on the CPU, but do i need to change memory multiplier so it doesnt exceed 800mhz?

Also im not sure what to do with memory latencies, at the moment they are all set in the BIOS to 4-4-4-12 which is the GeIL's speeds, but do i need to increase them as i overclock? This is another area im confused in... :confused:

Thanks for your help, any general advice on what settings you guys use etc would be fantastic

Oh and im using an Arctic Cooling 7 HSF.

So set the RAM to 5-5-5-13, or set the memory multiplier down one to 2.50 (rather than 2.66)?

Would i need to increase the VCORE voltage for this, its currently at 1.32 something i think...

Lovely stuff, ill give your settings a try.

I had a quick tweak before i noticed your post, and on some settings i seem to get nothing but a flashing underscore in the top left of the screen after POST and nothing else which is strange. After which i have to hard-reset and change back the settings in the BIOS. Using the F6 BIOS. Just curious if anyone knows what thats about? :confused:

I have exactly the same CPU, mobo & memory setup. Update to the latest BIOS & try these settings:

Limit CPUID - Disabled
C1E - Disabled
TM2 - Disabled
CPU EIST - Disabled
Virtualization - Disabled

CPU Clock Ratio (Multiplier): x8
CPU Host Frequency (FSB): 425
System Memory Multiplier: x2
Timings: 4,4,4,12
Memory voltage: +0.3 (stock)
MCH voltage: +0.1
CPU voltage: +0.1 (1.425)
Memory Performance: Fast

Leave all the other voltage controls at default. That will give you 3.4GHz and should be totally stable.

Ok, i followed this exactly. But after setting these and saving, the machine shut down and turned back on (as usual), but then just kept shutting down and coming back on, nothing would appear on the display and it stayed on for about 5 seconds, then off for about 5 seconds before switching itself back on and going over it again! I cleared the CMOS and set everything as it was before, all is fine.

Whats going on, im using the latest BIOS, a Liberty 620w and set everything mentioned above...i have memtested my RAM and all is fine, and if i set all back to 9x multiplier, 300, 2.66 memory multiplier it is as solid as a rock, im confused, help?! :confused:

thats one annoying thing with this mobo, i can set things up in bios, save and exit, boot into windows, run orthos hours on end, shut down for the night,
switch on the next day, it go through the start>stop routine.

case panel stays off because the amount of times clearing cmos. sometimes it start, most time reset cmos job

leave it for some time if you can when it goes through stop-start routine , it might start.

lol, fair enough. I'll be honest, i think ill just leave it at the settings in my first post, 2.7ghz

. A nice little overclock that doesnt really increase temps, perfect enough for me - i guess i wont worry too much about the on/off loop if others have the same problem :eek:
