Basically i am a overclocker/tweaker but also a cheap ass and if i can save myself from a $100 psu then i will. =) Right now i am running my rig and its working fine. The question is.. Is my PSU holding my overclock back? Here are my specs.
AMD Phenom II 710 x3
Wintec 4GB DDR1333 running at 1666
Gigabyte GA-MA790XT-UD4P motherboard
AMD/ATI 4870x2 graphics card
Cool IT Freezone ELITE cpu cooler (modified to chill my waterloop.)
1 sata optical DVD burner
3x hard drives
Antec 550watt Neopower (check out review for specs) Antec NeoPower 550 Power Supply Review | Hardware Secrets
So far i can get an overclock of 3.575ghz at DDR3 1450 or so. It seems rock solid stable at this setting as i have been playing several games for several hours. however i simply cannot go beyond this. I need to know if my psu is causing this.
When i first turn on the pc i can hear my fans vary in rpm before it posts could that mean the psu is overstressed and can barely handle the load? can anyone recommend a good way to verify this?
My current settings are
Multiplier: x13
FSB: 275mhz
cpu voltage: 1.525
I have the HT throttled down to 1500mhz for now.
if i increase the fsb to 276 i get no post.
It feels like i am hitting a FSB wall. I can post with multiplier of 10 and fsb of 280 which is 2.8ghz but when i use multiplier of 10 with 300fsb for 3ghz i get no post.
Does this mean my motherboard is at fault or just a powersupply not having enough juice?
