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

Nope.

Over the weekend I switched from 2x 320g Seagate RAID0 to a 150gig Raptor and the faster access times certainly has made life quicker.

I also put in 4 1GB sticks of Crucial Ballistic PC2-8000 and they're working at 4-4-4-11 1T at stock speeds. So far so good, but I have a long way to go to see how much they'll last at 1T.

[killingspreez]

what?
you are able to run 1t stable?
i can't believe that...i tried this for hours!
could you post screenshot of bios/prime stbility (ram)

regards

[Borgod]

I dont have any screenshots, but OCCT completed 7.5 hours of CPU&RAM (blend) thismorning at 2.7Ghz with QX6700 @ 4-4-4-11 1T

As I have switched back to air cooling, I won't be doing too much CPU overclocking as the Tuniq Tower isn't anywhere near as effective as cooling as it was when on water. I'll certainly play with the FSB however.

1T @ 500 mhz ?

[Borgod]

If I can do that, I'll send you an Aussie beer

[killingspreez]

deal

well i can't even do 400mhz 1t stable (memtest show errors), prime fails but super-pi runs all the way without problems......hm uping voltage didn't help so far....and the timings have just very very little affect on the 1t-stability-issue

this is my highest primeclock so far on my dfi
no matter what i do, i can't get fsb 450 stable :/

Anyone got his ram killed by this board ?

[killingspreez]

i think so.
if you make sure that you have a proper ram cooling and you don't give too much volt and leave ram drive strength on weak there shouldn't be any problem

GNU, what software did you use to measure your 210MB/s single and 400MB/s in Raid configuration?

HD-Tach

I'm having extreme difficulties installing Vista using the 4 DIMM slots. It just crashes with blue screens.

I had this problem when installing with 2 sticks, but that was because I was using 2T in the orang slots.

XP works perfect, and all Memory Diagnostics and memtest testing comes up with no errors.

Bizarre.

[Grinch]

stick with XP until vista is more stable...problem fixed...*-)

[killingspreez]

i installed vista with 4 stickts, too.
maybe rise voltage a little bit 2,05 or 2,1.

There is a known bug with Installing Vista with more than 3GB of RAM... http://support.microsoft.com/kb/929777

Try removing some RAM, installing Vista, applying the patch, and then reinstalling the rest of your RAM.

500*7 nice!
i'm really having a hard time to get 8*450 with 4*1gb stable.
also i can't go above 470 htt....any advices?

24/7 ? that seems impressive. are u able to run a blend test for about an hour ?

[Brother Esau]

Whats the max recommended FSB for 24/7 use on the 680i chipset?

[Wiggy McShades]

Whats the max recommended FSB for 24/7 use on the 680i chipset?

ive got 455 x 8 on an E6700 1.51v set in bios on the nb 24/7 stable. i think its really what voltage on the nb is recommended for 24/7, but i know with the strong cpu drive strength i cant set much above 1.5v without it just totally not booting

[Brother Esau]

@3325MHZ 475 FSB Ram @4-4-4-10-4-21-5-9-7.8us @1:1
Vcore 1.3815V CPU FSB 1.30V NB 1.5V SB 1.40V HT 1.25 VDimm 2.25V

But can the chipset handle these kind of high frequencies for extended period of time? It passes Prime95 for 10hrs at these settings no problems!

Yeah thats what I had to do in the end, but I wasn't aware it was an official bug.

I decided to stay with XP anyway.

Orthos blend test 1h
I also run orthos small FFts test about 8+h, but i don't have a screenshot.

[BAR*B*Q]

really impressive

can u tell something about bandwidth scale ?

[killingspreez]

does any1 know if there is already a new revision?
what revision do u have?
i'll picture my sticker tomorrow!
