So no one has tried putting a waterblock on the NB? :confused:

Does 4GB of Ram ( 4 x 1GB ) influence the OC ?

it usually does, yes....makes it harder to clock as high with only 2 x 1gb

supposed to be released this week was what i remember reading on here.

been reading a while and just ordered one. just want to get some confirmation is it any cpu heatsink with blackplate mounting cannot be used in this evga?

I wonder how this mobo will compare to the new asus 680i solutions.

I use a backplate with a Tuniq Tower 120. As long as the backplate has some sort of pad and the legs are elevated a little, you should have no problems.

amazingly overclocks well

so would it help to add the additional 2x1gb afterwards to have a total of 4gbs?

1) I have a 449FSB limit that other people also have ( ignoring holes which is another issue)
2) 3d performance is poor compared to 975 unless 1T with linked ratio that is also in sync and then it is better by a small amount.
3) ntune does not work for me at all.

thanks for your reply. i noticed that the review did by anandtech used Tuniq too. too bad i hardly find it here. currently all i can figure out is scythe ninja rev 2 where it doesn't need backplate mounting.

I am running a DD Maze4

And for you guys asking about the P20 BIOS. It is in final testing and should be released this week. :banana:

That's good news, I'm getting my evga 680i tomorrow :)

Does it allow higher 1T speeds?

2 days, still playing with air:) ....I will keep tryin..

Slower than 975X with same settings..

Yes it does allow 1T timings, although, memory 800MHz and higher may have a difficult time being stable at 1T.

Try to find the best tweak for this EVGA 680i and the 8800GTX - here a few runs with:

- CPU @ 4.5Ghz cooled by Vapo LS
- SINGLE EVGA 8800GTX stock cooler @ 635-1000

Think is not to bad for single graphic card with stock cooler ;)

He meant does it allow higher 1T speeds than what we seem to be seeing. The wall for 1T right now seems to be around 800mhz...

What I want to know is if it adresses all of the FSB holes/dead spots we are seeing.

If you raise and lower the FSB and memory frequencies in increments of 5 (1505, 1510, 1515), you should have no problems. At least I haven't since I started doing that. For memory overclocking I would recommend running "Unlinked".

Yes, but you are using a 6800...people that seem to be having fewer dead spots are those running the extremes. I've used the 5mhz jumps to no avail on a 6400 and a 6600. Between the two the dead spots are in the same area. On the 6400 I was able to start an orthos session at 468mhz which failed and there after was never able to return to it so it was an unusable/unrepeatable area. I just got lucky being able to boot there in the first place.

The problem with unlinked is that it slows the system down compared to 975. To give better than 975 performance ( at least slightly ) you have to run linked and SYNC which gives the half memory speed as per 975.

I have the 449 FSB wall as well, however my Crucial Balliastix will run 1T up to 449 no problem.

what are you using to cool the SB?

Difference between linked and unlinked is marginal.

Linked
8M = 3m 11.797s

Unlinked
8M = 3m 12.610s

I'm using XP SP2, so times aren't that great. But if you want very high memory speed, you almost have to use unlinked mode on this board.

Maybe for Spi but for 3dmark2001 you get a big hit.

Unlinked 12x300 800 Ram = 47700
Linked sync 12x300 800 RAM = 48200

500 points takes another 100Mhz FSB to get back to level so unlinked you have to run 400x9 800 to get 48100 or so.

I lost over 10fps in lobby low and similar amount in lobby high.

That's interesting. I don't run 3DMark anymore. I mainly test with Pi and occasionally run Orthos, just to satisfy the stability freaks.;)

I just tried 400X9 linked & unlinked with memory at 533. They were virtually even again in 8M.

I tried booting in linked mode with memory at DDR2-1200. Got the infamous long beep. I switched to unlinked mode and booted at DDR2-1280 with no problems.

I'm testing with Corsair 6400C3 at the moment.
