i want to max out my little brisbane to a maximum


i have a tforce 570sli, 1gb Ocz platinum, 1 gb G.gkill, Zalman CNPS9500led, and a aspire 520W PSU

i'm currently @ 2.3 ghz with CPU frequency @ 242 x 9.5 i can't seem to get it over 252 (screen BSOD's at windows load) i upped the voltage all the way to 1.475 and still couldn't get over that barrier.

i was thinking my PSU is holding me back because
1. Its a tier 5 on the tom's power supply guide
2. My mobo is 8 pin CPU power and PSU only has 4 pin

I also wanted a new PSU with the 8 pin CPU connector or a 4+4 config.



THANKS!

Are you OC'ing your ram too? If so, double check to make sure that your ram isn't the problem. Either drop your CPU multiplier to the min or reduce the ram speed ratio to get the ram down to stock speeds and see if that works.

If not, you could have a poor overclocking CPU or MB, though IIRC the Biostar Tforce 5 series are good OC'ers.

Given that your PSU is a POS, I would replace it anyway, even if I wasn't overclocking.

nope i'm setting RAM dividers

currently its running at 380(760) mhz. DDR2 667 divider.

and cpu multi is locked. or so i think....

A) Make sure you have the most recent bios. If you do not and the motherboard is detecting faulty temperature readings from a brisbane processor, it WILL cause instability as it attempts to prevent the processor from overheating (even though it really isn't).

B) REPLACE your PSU. Don't even consider trying to use an old POS PSU for a decent OC build. Don't get me wrong, I'm not suggesting you need a high-end PSU, but you need something of at least medium quality.

C) Reduce your multipier to 6 and figure out for sure where the limits of your board and ram are, then adjust the CPU to best match.

for "C" do i revert everything back to default, i.e. clock freq. RAM speed, RAM divider, etc....

i do have the most recent bios and motherboard reads temps perfectly fine.

im thinking its the psu, i'm getting a new one on eBay asap than.

bidding on a bfg 650 watt. with a 4+4 pin =]

Avoid the BFG PSU - it's just a re-brand of some other manufacturer's PSU. Even if its a good quality unit, you'll pay more just to get the BFG brand - and there's no guarantee they picked a good PSU. Stay with tier 1 or 2 if you can afford them, tier 3 if not.

i cancelled my bid following your advice. could someone link me to the power supply tier thing, i can't seem to find it on google.

Here is a link to a review of the X2 3600+ Brisbane.

What is your HT multiplier at? Set it to 4x

woot got it at 2.4, i got it up to 2.3 previously but now i got it to 2.4 (bad RAM wouldn't get over 242 CPU freq.) Shooting for 3.

You may need to reduce your HT and your ram. Many mobos will only do 242 + at HT 3X or less. Your RAM may need set to 533. Note 4 X 42 is 168 and 168 + 667 is pushing DDR2 800 even for a well know OCing memory.

ok at 2.4 i have the settings as follows.

RAM= 667 on cpu-z ram is running at full ddr2-800 speeds
HT= 4x on cpu-z HT is running at 1010.2 mhz
FREQ= 252 on cpu-z is running @ 2.4ghz
CPU volts= 1.375
RAM volts= 2.1

system specs=

x2 3600
tforce 570sli
Corsair xms 2x512
Dynapower 500w PSU 28A on +12v
zalman cnps9500 w/ amd clip

any help/advice would be welcome!
