Some suggestion on OC my system??

post #1 of 7
Thread Starter 
I'd appreciate any help you guys can give me, i'm trying to get all i can from my current 939 system before i upgrade. I ended up ugrading my CPU to an Opty 180(should have got a 170 or 175 ) but i think i'm being held back by my old A8N SLI Deluxe and bios 1016. I can't seem to find anything on overclocking my cpu with this board, can i get some suggestions on how to do a stable overclock on air cooling.. Thanks everyone.

Well, you can go into the bios and start changing the fsb, increasing slowly till cpu temperatures are too high.

So what have you tried this far? Have you found the max fsb the board will do? If not then it will be trial and error. First drop the ram 200 to 133 to give you some headroom to know it wont hold you back. Then drop the ht multi to 3 for now. With the stock cpu multi, incremently up the fsb by 5-10 mhz at a time and see if you can boot to windows. After every 20mhz increase run orthos for 5 mins, if it passes keep on upping in small increments till it either wont boot or bsod. If this happens its either time for a notch up of vcore, or if your ram has surpassed 200 again (check with cpuz) drop to the next divider. Continue this till you need more than 1.5 vcore to pass orthos for 5mins. Remember to keep a eye on the temps and make sure either core dosnt go over 55c, if it does lower the vcore untill acceptable temps are reached (may require you to drop the fsb also) then see if you can run orthos for twelve plus hours. If it errors out drop the fsb 5 again and so on and son. You get the idea right?

Start with your RAM @ 2.8v and set it to DDR333 or 166MHz.
Slowly increase the CPUs bus speed in the "Advanced" "CPU Configuration section of the BIOS.
The Optys don't usually need a lot of voltage, perhaps the mid 1.4v range but do watch the full load temps when testing for stability with Orthos or OCCT and keep @ or below 50c.


There are a few key screen shots missing but its still a good read

Well, i managed a stable overclock at 2640 for right now, i ran Orthos for about 6 hours with no errors. The highest i got the fsb to was 235 but Orthos reported an error after 10 minutes, i did manage to boot to windows though. Here are my current settings....
CPU:

FSB:220
Multiplier:12x
Htt:3x
Voltage: 1.40 ( bsod on voltage set to auto?)

Memory:

@DDR333
Latency: 2-3-3-6 2T
Voltage: 2.80

3DMark 06 score: 9433

It would be nice to get a stable OC with the fsb set to 250 but it's probably a reach with this motherboard?? What about lowering the multiplier, dropping the ram, or maybe bumping up the CPU voltage a little more? Either way at least this baby is stable for now, thanks for all your help..

Well, if you want to know your motherboard's limits, here's what you do:

Reset all voltage settings to stock.

Drop your CPU multiplier to something low, like 5 or 6.

Drop your RAM divider to its lowest.

Then crank up your HT ("FSB") in 10MHz jumps and boot into the OS.

The point at which you can't boot into the OS (which should still be below your CPU's stock speed setting) is your motherboard's limit on "FSB" scalability.

I like to make up separate charts when I overclock. One chart with settings changes and their effects for motherboard's max HT ("FSB"), CPU's max speed, and RAM's max.

Of course, I'm possibly more anal than most. On the other hand, I like archiving data so that I can analyze errors better and understand why an overclock fails if/when it does. (Oh, and it props up my very weak memory -- not RAM, but my brain! )

Hope this helps!
