Hi, i just grabbed some Corsair TwinX XMS Pro 2x512mb DDR500 just wondering if i can grab some overclocking tips, my specs r...

AMD X2 3800+ 939 Manchester CPU
ASUS A8N-SLI Motherboard
PixelView 7800GT 256MB G/Card PCI-E
Antec 500w Power Supply
80gig SATA

Ive tried to run the ram at 250mhz but its not working ? Its currently at 220mhz wtf.

What are you running it at? What are the timings, voltages and speeds? What are the timings, voltages and speeds it is rated for? You have not given nearly enough info.

Motherboard: Asus a8n-sli nforce4
Memory: Corsair XMS TwinX Pro DDR500 PC4000 2x512mb running 230.1mhz on 2.60v with 3-4-4-8 timings
Cpu: AMD x2 3800+ Manchester Soc 939 running at 2.3gig on 1.344v tempreture at 40d/c multiplier x10
P/Supply: Antec 500w
V/Card: Pixelview 7800GT 256mb
H/Drive: 80gig SATA
Cpu Cooler: Zalman Fatality

Hope thats enough

I have DDR500 ram and my computer is saying at startup DDR400, it wont read it at ddr500 even after i change it in bios, it goes back to ddr400, im running dual channel azwell any advice would be great thanks.

Raise the memory voltage to 2.8-2.9v (above this if the BIOS allows but you'll need to have some good airflow directed over the memory) as at that voltage those sticks will only work at DDR400 settings I believe though you may also want to knock the HTT down to a multiplier of 4 or 3 instead of 5.

Cool ill try that and get back to ya.

No such luck wayout44, i am running 240mhz on same timings but at 2.70v seems ok but i will wait and see, could my motherboard be affecting the ram since it reads ddr400 all the time ?

Use this program: http://www.cpuid.com/cpuz.php to read the speed of your ram in windows.

Are you just turning the ram up to 250MHz with a divider or are you overclocking the HTT to 250 with the ram 1:1? PC4000 (ddr500) is made for overclocking since you can run the HTT up to 250 and not worry about ram speeds. Otherwise, running the ram faster than the CPU is not a good idea on that platform.

Ive already got cpu-z ill send in some pics in
