GA-EP45-DS4P with 4gb dual channel 1066 ram problems

[nev]

Hi,

I'm having problems with my ram running in dual channel mode.

First thing to state up front.
Running the ram in dual channel mode - memtest86+ (2.01) passes all the tests!
However it fails when I run the Windows Memory Diagnostic tool. (On INVC, LRAND & WINVC)

Is this to be expected? When windiag runs it says that it "could not process the system memory map... As a result, not all of the computer memory will be tested. The memory map contained ranges that extended above four gigabytes."

So my first question is, should I just ignore windiag?

If I run windiag with just one of the 2gig sticks in, it works fine. And testing the other stick works fine as well.

Otherwise, my system is:
GA-EP45-DS4P
Q9550
Corsair HX620W
Gigabyte GTX260 gpu
2 1TB seagate drives in RAID (although I will be running 4)

4GB Patriot Viper memory - PVS24G8500ELKR2
5-5-5-15 2.1v

Everything is set to original settings in bios except :
CIA2 disabled
Performance Enhance Standard
XMP disabled
MCH Core 1.3v
DRAM Voltage 2.1v
CMD 2

Thanks

Windows Memory Diagnostics is JUNK! If you ram is passing Memtest86+ for sure then your ram is fine!!!!

If you want to be really sure it is memtest86+ stable, aside from the full tests you can run single tests for as long as you like. I would suggest you run #2, 5, 6, & 8 separately for maybe a hour each. Here is how to run single tests >>>

1. First press C
2. then 1
3. then 3
4. and finally select the test that you want to run
5. press Enter
6. and then 0 to get it running

By the way, how long did you run Memtest86+?

Your settings sound good, although AUTO will not give you the best performance, they should be usable with what you have stated you changed. Provided trfc is above or between 48-62

What System are you running? And is it 32 or 64 bit?

change MCH latch speed
400mhz worked on f5 but with new F6bios 400mhz mch latch does not work
333 did not boot
200mhz booted and i am in the process of testing >

set system memory multiplyer to 2.66x (a,b,c,d depending which MCH latch you have manually chosen ---- please note each time you change MCH latch the multiplyer will change to AUTO > change back to 2.66x



edit :: at 333mhz MCH feq latch there is option for 2.00b multiplyer and 2.4
so diff MCH latch allow diff multiplyer > 200mhz and 400mhz have same options for multyplyer
333 and 266mhz have different
so far i have only had successfull boot on 200mhz FSB feq latch
i will test 266 later
