F2-6400CL4D DDR2-800 & K9A2 problems

[Uhsul]

I used the G.SKILL Ram Configurator to find faster lower latency DDR2 for my MSI K9A2 platinum mobo, it suggested the F2-6400CL4D-4GBPI-B DDR2-800, so I bought 2 pairs. They arrived this afternoon, I installed them and Win 7 64bit wouldn't boot up, so I removed one pair, and then Windows loaded right up, changed to the other pair - same results Windows booted fine, but when I replaced all 4 back to square one. Any suggestions?

K9A2 Platinum
AMD Phenom Quad Core 9850 black edition
Hitachi DHS721010 1T HD
Corsair TX850W PS
2 ATI Radeon HD5770 1gb DDR5 (Crossfired)

You can try it with the stock timings and DRAM Voltage. Will need the tRFC up to 195 and Command Rate/Timing at 2N. Also with the 4 sticks will prob need to OC things a bit and raise the CPU, MCH and HT voltages

[GSKILL TECH]

NB Voltage 1.40V

If you can post up BIOS pictures, we can see if anything is incorrect.

Thank you

Having similar issues

Overclocking Newbie here... so please be patient with me.
Setup:
MSI K9A2 Platinum
AMD Phenom 9950 Quad
Windows 7 Pro X64
4x1 667MHz Dell memory (now)
4x2 G.Skill F2-6400CL5D-4GBPQ (trying to get working)
Dual ATI 512MB 3850's Crossfired
SATA1 WD Black - 1TB - OS/Apps
SATA2 WD Green - 1.5TB - Storage
SATA3 Maxtor 500GB - Swap File
SATA4 BluRay/DVDRW Combo

When memory is installed, will sometimes boot but with an Overclocking error in the post. Once up and running, seems to work fine until I shut it down.

I see I should set the memory to 5-5-5-15-2T, 1.8-2.0 voltage. Problem is, I have no idea what that means and have nothing in the BIOS that gives me those options.

Downloaded and installed AMD OverDrive 3.2.1 but it's intimidating me, I don't know what to set to those numbers given above. MSI says it should work once I get it configured but that's all the help I can get from them...lol

Funny, can't get this to work in my $200 super duper MB, but works fine in my wife's $39.00 bargain bin ASUS...

Anyway, any help at all will be appreciated.

Thanks in Advance... )

oops, wrong thread...

Think I posted this in the wrong thread... too much browsing whilst waiting for my ID to be confirmed... Will start a new thread I guess.

ccwoodcraft,

You have the same problem as the original poster. You guys need to go to the Cell Menu, scroll down to NB Voltage, and set that to 1.40V.

Thank you
