View Full Version : Memory Hard locked at 200mhz in bios

06-30-05, 08:45 PM
Currently have a Giga-Byte K8NS Ultra-939 and want to start overclocking and for some reason there is a limit on the memory clock at 200mhz(400 DDR) any ideas. BTW is it nessasary to keep mem or processore synced on nforce 3-ultra? Is the nforce 3 ultra HT freq 1000mhz?

Thanks in advance.

Have you tried to open advanced chipset features (control + F1) in the bios?

What about Gigabyte's utility program, EasyTune5?

All It has is system bus Im not sure if it is getting the memory or not

EasyTune5 is a software program that shows cpu, motherboard, & power supply temps, as well as software oc'ing capability. Being that you could not change settings in the bios 'advanced chipset settings' screen I doubt the software program would be any help.
Might check your bios version, presently F6 is the latest as I just checked here: http://tw.giga-byte.com/Motherboard/Support/BIOS/BIOS_GA-K8NS%20Ultra-939.htm

Also EasyTune5 can be downloaded from the Gigabyte site.

Im noob at OC Athlon 64 but this is what i have done on my X2 . Don't keep my mem in sync and performance is good i have put my 200(DDR400) to (DDR333) , LDT from 5x to 4x and rised FSB/HTT from 200 to 240 , Multy is same 11. Memory T1 cas 3 . Higher HTT no go for me with these settings don't want to try high volts and T2 cas 4 combinations.
2200mhz to 2640 seems awesome to me :p and i think only NF4 got (1000)2000 HT everyone else 1600(800) not that i know what it does.

it is getting the memory :)

the ddr speed in the advanced config page, is the memory divider, 200 is the 1:1 divider, 166 is the 5:6 divider etc. Set the ram to 200 on that page, and it'll use whatever setting you specify for the system bus. i.e. i use ram @200 and bus @220 to get my ram running at 220 (440 DDR).

likewise ram set at 166 (5:6 divider) and bus at 220 puts the ram around 180, or 220 /6 *5.
