Case & PSU: Antec 200 with Vantec ION2+ 600w Both New


GPU: Used GS 8400(Used BUT works fine)



So here is what we have done:-
In MT intelligent Tweaker(MIT) we tried changing the following ALL without Success Nothing else was changed:-
1. Set Memory clock to Manual to X5.33 = 1066 (Timings set to AUTO)
Wont reboot comes up with Error and wants to go into Repair OptionSTILL Wont reboot comes up with Error and wants to go ino Repair Option


3. Updated BIOS from Version F4 to F9
STILL Wont reboot comes up with Error and wants to go into Repair Option

As soon as we simply reset the memory clock back to X4 = 800
No problems Reboots staright away


This Moboard is probably a couple of years old .....Just wondering as we are now running Win 7 64bit DO we neeed to update the Chipset/Raid ?

Haven'y tried it, Just dont wont to crash it....as it works fine at 800 JUST that we have Paid a premium for the 1066 and want it to run at 1066

*Their is a footnote stating that this board supports 1066 according to the type of CPU etc.....and the AMD x2 7750 is on the list
The Patriot viper is not on the Memory Vendor list BUT then again it wasn't on the market when this board was released


*Quote from GB site for this board

You will need to raise your memory controller voltage (NB VID), possibly increase tRFC and set your ram voltage before this is going to work. You may also need to increase your NB Freqency as well.

If you continue to have issues, please PM Artdrivers and ask him if he can help you, he is our AMD expert here >>
