help me oc my TWIN2X2048-6400C4DHX


Recommended Posts

Hi guys,

 

I am overclocking my amd 6000+ to 3500Mhz :biggrin:

I had no Problem with this speed when i made the ram speed 800Mhz

but i need the ram to be 1000Mhz,Unfortunately i don't know how to make it stable

I cant pass the memtest @ 1000Mhz

 

This is my setting

 

250 X 14x = 3500

HT x4

Memory Clock Freq : Auto

 

CPU @ 3500

Ram @ 1000

HT @ 1000

 

CPU Volt 1.65v

Ram Volt 2.2v

NB Volt 1.55v

 

Ram Timming 5-5-5-15-2t

 

I can login in vista but as soon as i do anything i get BSOD

 

Please help

There is NO guarantee that you can make 1000Mhz stable from that 800Mhz DRAM. Might not work.

 

Download memtest from--->
and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Download CPU-z from
.

Please post screenshots of your CPU-z CPU/Memory and SPD tabs.

Download Core Temp-->

Please post a screenshot of your Core Temp.

 

The math:

 

200 : 800 as 250 : X

(250*800)/200X

X = 1000

Thus at 250Mhz FSB, your 800Mhz setting of the DRAM will concurrently rise to 1000Mhz. Set the timings to 5-5-5-15 2T, DRAM Voltage to 2.1v and the MCH to 1.45v

I would lower your

 

CPU<->NB HT Speed: 4X

NB --> SB HT Speed: 4X

 

^^Agreed^^

 

Your DRAM voltage is high enough and you have tested fine at the memory level. Lower your HT link to 4X. The NB --> SB HT Speed lowered will allow for a cooler running NB --> SB and this is preferable as well.

I did the following

1- check if cpu is stable

i lowered the ram speed and found that the cpu is stable at v1.47

 

2- try to make ram stable at 980Mhz

i tested using orthos starting with v2.1 all the way to v2.3

but no luck i cant finish 5min

Do i give it more voltage or its not going to be stable at this speed

I wouldnt over volt your memory it wont be covered if you do. Dont go above 2.1V. I found that it can be stable between 800-900 this is what I have mine at 24/7.
