Dear Sirs..

 

My problem is this...

Windows 7 RC1 couldnt be installed .. (many blue screens)

and windows XP had random reset issues...

runned memtest for 6 hours (boot iso) but no problem with Corsair memory shown

(btw running memory at 1-3 Dimm, and BIOS settings to auto)..

 

Replaced Corsair memory dimms with my old (2 year) Mus 800hz.. 2gb (2x1gb, dual ddr, 1-3)

 

and windows 7 rc1 installed fine... no random resets in XP..

(btw both Win7 and WinXP are fresh installs)...

 

any ideas on how should i make my Corsair memories work nornal with my Motherboard??

(btw Motherboard has the latest firmware F9)..

 

Thank u in advance

Please make sure that you have the latest bios and load setup defaults and then set the memory Voltage to 2.1 Volts then set the timings manually to the tested settings for the specific module you have, and test the modules one at a time with http://www.memtest.org to be sure one is not failing. If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test.

a) As i said to my first post memtest does NOT produce any errors (it ran for about 6h)

 

b) i ve checked

Dram Voltage in MB

 

Dram Voltage 1,800V auto

Dram Termination 0,900V auto

Channel A 0,900V auto

Channel B 0,900V auto

 

what manual values should i put to them (with the corsair i have)

 

i repeat again.. my mush 800hz, 1x1gb=2gb running at dual channel produces no errors (in both xp and win 7)

the corsair i have (1066hz), althouth i produces NO erros in memtest

it is unstable in both XP and 7 (win 7 could not be installed)...

 

any suggestions??

If you set the memory frequency to DDR1066 then you will have to set the memory Voltage to 2.1 Volts as well and if you do not get errors in memtest that would suggest some other issue.

runing the pc now with mus memories for 10+ hours and no problem...

 

corsair 15 min ..and machine crashes so 100% a memory issue...

 

have corsair on 1066

but DRAM Dram Voltage 1,800V this one i should put it to 2,1? (cause motherboard has it in red letters? is it safe?)

dram termination should be in 0,9? and channel a and b to 0,9 also?

If you did not set the memory voltage that may be why you are having problems?? Yes set it to 2.1 Volts!
