[First Look] DFI 680i LT NF-680i LT SLI (56K Warning~~~)

[Grinch]

I got this board last week and so far its reasonably good in most ways and very good in others.

I have found it more stable than the BFG 680i i had before and can get rock solid stability at 450FSB.

Got my chipset water blocks today... Link mofset, Nb and SB so will let you know when all setup and running.

looking forward to it

For info.

I suffered some really wierd issues over the weekend with the board.

First i flashed to 521 from the official site and all was well with my X6800 (indeed it did 4.5 without issue on freon). The i changed to my E6600 and could not find multi unlocking...

So i flashed to Beta 504 and sure enough the multi unlocking came up, but other parts of the bios were poor. so i flashed back to 521. On doing this the multi unlocked remained... good news i thought... No this is when the really wierd stuff happened.

At this point i could not get stable even at stock. In windows as i moved the mouse, or accessed HD the num lock keyboard loght would flash and ther would be a stuttering. This only happened when using Raid. After a few moments the system would just freeze.

I trued battery out etc - nothing worked. In the end i flashed back to 504. then flashed back to 521 - removing the battery between each flash. I also flashed in Windows XP using Winflash and did the old DFI trick of flash once and then without re booing flash again.

Anyway that got me back to stable, but no multi unlocked.... so for me 521 does not enable downward multi's which is a pain.

hrmm... ive never heard of anything like those issues... when i flash the BIOS i just winflash it once and have never removed the battery afterwards.

as far as switching processors... ya i could see some trouble with that. are you sure you're removing the battery for long enough? the last time i did the BIOS reported a new CPU detected and installed the proper siprom table for it...

Are you using the 4CTST or the 2CTST version of 521. The 2CTST should have unlocked downward multis... at least it does for me.

using 4CTST - ah so ic the 2CTST is 2 core and the 4CTST is quad... That explains why there are so many different versions on the DFI site... wonder why i picked the 4CTST i normally just pick the top one and now the 2CTST is at the top... maybe it was not there when i downloaded originally... oh well.

Anyway flashed to 2CTST and multi's are there again. Many thanks for the info

4CT bios is for XE edition cpu's including the dual core versions, for all upward locked (non XE's) multi cpu's use 2CT..
