OCZ ModXStream Pro OCZ600MXSP 600W ATX12V V2.2 / EPS12V SLI Certified CrossFire Ready 80 PLUS Certified Modular Active PFC



I have tried setting the voltages up but it only seems to set the ram to 533Mhz. As for the CPU, it's stock at 2.5 and I cannot get it any higher than that. I'm still fairly new at this, but I am familiar with the bios and currently have my ram settings at:

Set VDDNB Overvoltage to {1.35 volts} [ +100 mv ]

Set Memory Clock Mode to {Manual}
Set Memclock value to {533 Mhz}
Set Memory Timings to 5-5-5-18 (CL-TRCD-TRP-TRAS)
Set Memory Overvoltage to {2.1 - 2.2 volts}


I just wonder if I am missing something because every time I try to set the CPU higher, it either won't boot windows or it won't run for more than mins before blue screen. If someone could give me some basic setting to test, it would be much appreciated!

Thanks

lol that is your problem, you need a real motherboard, I see you spend your money on the processor lol, but a motherboard is more importan if you want to OC, Spend MOAR money on it to get all the features, but there are alot of 100$ mobos that can take your AMD to around 4.6Ghz and keep it stable. Your card is a Low end card too but ATI tool or AMD Overdrive(is better) will give you a bit more power out of a 5830 but not much and that will be your bottleneck in gaming/design fps and abilities. OH and AMD chip are overvolted in the first place, leave it normal of 8-9 settings above defualt settings and you should be fine.

Part of your problem is the first gen Phenom's aren't that great, and don't overclock well. You should read the overclocking guide at the top of the forum to get a better idea of what your doing.

What is the recommended voltage and timing for your ram? Kingston should have put it on the box or on the sticks themselves.

What a couple of tools trying to answer some simple questions. They talk big but don't know $#@$ about pc's. All you did is raze the guy about what hardware he should've bought based on your egos...

First you need to know your baseline specs for cpu:
Frequency (MHz) 2500
Bus speed (MHz) 533 MHz Memory controller
One 2000 MHz 16-bit HyperTransport link
Clock multiplier 12.5
V core (V) 1.2 - 1.3
V NorthBridge (V) 1.3
Maximum operating temperature (°C) 55 - 61
Thermal Design Power (W) 125

Simple answer would be:
1st: update your bios to v.1006
2nd: To oc your CPU, change it's clock muliplier. For example: from x12.5 to x13.5 if you want 2700 MHz. For 3000 MHz your multiplier would be x15.
In your Bios this would be under:
Advanced > Processor Frequency Multiplier
Selecting that will give you a list of mulipliers and the resulting MHz of selection.

And manually set:
CPU OverClocking > CPU/HT Reference Clock (MHz) [ 200 ]
GPU OverClocking > GPU Engine Clock [ 800 ]
Memory Clock Mode > Memclock Value [ 533MHz ]
DRAM Timing Mode [ Both ]

For the Kingston HyperX Memory: 2.2v for 1066 MHz / Timing: 5-5-5-15
If the aggressive timing isn't stable, try: 5-7-7-18

Heat is the main issue of CPU oc'g and stability. Don't go above 55°C to avoid damage.
For hardcore oc'g you'd need to do your own deep research to learn what does what in the bios and the specs of your hardware and it's limits. The Asus M4A785-M isn't a bad board. You could've done alot worse with other brands. And the old philosophy of oc'g was to make low-end hardware do what high-end hardware can do for alot less money.
