Im tryin to OC my socket 754 newcastle. I got it to 2.59 with no problems. As soon as I set it to 2.6, the system shuts down and restarts itself with the stock settings. Does anyone know why? How do I OC my memory?
 
have you lowered the multiplier for the HTT (also known as LDT)? if you push the HTT speed too far that will cause stability issues.
also, consider using a lower memory divider.
also, take a look at this thread, it may give you a better insight into whats going on http://www.computerforum.com/showthread.php?t=16346

bear in mind you may have simply reached the limits of your system
 
I still cant get it to 2.6 so Im gonna give my settings and see if anyone can help.
CPU Clock Ratio-10
CPU Overclock in MHZ- 259
Clock Spread Spectrum- Enabled
CPU Voltage Control- 1.55volts
VDDQ Voltage Control- Normal
VCC12_HT Voltage Control- +.3volts
DDR Voltage Control- +.2volts

Can anyone help me to get my processor to 2.6ghz. I have a
Gigabyte k8ns-pro motherboard.
 
Have you set in place memory dividers/lowered the HTT on your motherboard like Hairy Lee said? What are they at if you have...
 
have you tried bumping up the cpu voltage a little more?
the HTT is often found in chipset configuration and will either be called HTT, Hypertransport or LDT. look for that and make sure that you drop multiplier down to 3.
 
The memory divider will be found in the section with your RAM timings and such usually. It should be a ratio or fraction (ex. 2/3, 9/10). Try and set it to the closest to 1. (maybe 7/8 or 9/10) and see if taht does anything.
 
I dropped the multiplier to 3. But my board has like 6 different memory settings. Im not sure which one to change.
 
ok, lower your memory divider (basically a multiplier thats less than 1) and lower your hypertransport multiplier to 3 maybe? (200mhz default x3 = 600mhz, 220mhz x 3 = 660mhz)
ddr333= ddr400 x 0.83
 
here are the memory settings I was telling you about. Which Of these do I have to change to OC my computer.
