You may need higher tRFC then 42, maybe 50 - 55.

You can try to flash to latest version of BIOS and see if it any change of that tRFC.


Read this, I know it´s about OCZ memory but G.Skill may have the same problem with ASUS board.

Bingo.

This is exactly why you "can't run rated speeds"

In 99.52% of cases, you MUST loosen tRFC, usually to at least 50+, to run 2x2 GB kits @ 500 MHz.

Either update your bios (to see if Asus smartened up & included a looser tRFC option), run timings @ SPD/auto (as that will set tRFC looser, usually to 52), or accept that you ain't gonna get DDR2-1000.


Just as an FYI to you, you're going to have issues with basically every single 2x2 GB kit reaching DDR2-1000 if you don't run tRFC 50-55+, so RMAing is going to accomplish nothing.

That is kinda disappointing then, as my current bios will only allow tRFC of 45. I guess Ill have to do a bios flash Oh well, if it goes bad (like usual) ill have an excuse to RMA my board for a fourth time..

I should not go bad, only if you use the ASUS Update Utility it may go bad. Use ASUS EZ Flash2.

Download the latest file from ASUS and put that BIOSfile on to a USBstick (Fat16/32 format) and plug it in, set your "Legacy USB Support" to Enabled (Advanced, USB Configuration) then save changes and reboot and press ALT + F2 or Delete (and Tools menu) and ASUS EZ Flash 2 Utility and just switch with TAB between the drives until you find your file and then ENTER and your are flashing.


You can read this about how to flash on a ASUS board

EZ Flash is just that: EASY.

If you follow the instructions you should have no problems. The problems start when you flash from Windows.

yeah you may need that new bios to raise that...

I have this ram set and am currently running it at 450 FSB and the Ram at 1040 and it runs just fine. I mean there is a long shot chance that it is the Ram but most likely its the board.

My Abit handles this ram better than my last Asus p5ke did.

Yeah, I know how to flash/what is best to flahs it with. I had to RMa a board because I flashed over an overclock once, then had to do another rma because i used asusflash to try to revert to an older bios. Ive learned my lesson... Put it back to stock settings, and flash with the bios.

Demonbane, what is your tRFC on your abit?

Here's the link
Thanks for the link I just ordered those and was wondering how to run them in my MF

Ill try the flash later when I get home... Im gonna go pick up a junk satellite dish for a biquad antenna

If the flash works, and using a higher tRFC works, that would be wonderful. My fingers are crossed. Those that helped, you will not be forgotten
