You know that's a good idea. I got really close--all the way through post at 333 x 9 and to the XP screen--and then a blue screen error.

I really think it is a matter of setting the RAM a certain way. there are a bunch of settings that I need to know how to set. I betcha increasing the refresh time would help...just need to play around some more.

With the settings I have tried so far I can only run at 2800.

I think I may be juicing a bit too much--I did turn it down a touch--I will see what a little more can do.

Have you found the individual limits of your components? i.e. CPU, RAM, motherboard, etc.? If not, here's how to find your CPU's max:

Divider to 1:2 or whatever to slow it down a lot
CPU Multiplier to teh max!
Voltage to 1.65 (1.55 + 110%)
HTT multi on "Auto" (Note: I have never had any problems overclocking with this set on auto.)

And get cranking! I like my 10X multi because I can figure out frequencies really fast.

I will try that again but i was finding I could get a higher overall CPU frequency by using a lower multi. 7 has been working well--with a really high FSB and a low divider on the RAM. The Uber RAM I am using is making this a lot easier. I will try your suggestion.

EDIT: For instance right now when I run 343 x 8 I can get my RAM in that sweet spot of DDR550 which is it's spec anyway. And fromthere I sneak up a little ata time till I have to drop the HT to 2.5. That's the way I got the 3700+ KACAE up to 2800 on air on the A8NSLI. I am finding from repeated benchmarking that a tighter faster RAM is better than a high CPU frequency by itself.

EDIT: I did turn it down to 1.5 110% and it is running fine at 2750. I think for now 2750 is it. Until I get a better handle on how to tweak the RAM in BIOS.

Sounds great I had the most success on a 10x multi, but I have not tried lower multipliers. [Hijack] Do you think I might have better success at a lower multi and higher FSB, running a bigger divider? [/Hijack]

The DFI boards seem to like a high FSB. The A8NSLI likes a straight up x 10. I was getting a lot of luck with X 7 on the DFI with crasy high FSB (380) and it even tolerates a very high HT--I was getting the best benchmark results with a highstrung HT of 1104 or something like that. I found that the PCIe Bus can run up to 116 stable as well--although the benefit of that remains to be seen.

I think the real secret is in the total refresh time for the DRAM settings. The higher up you go the more it needs. However what that exact setting is for these DDR600 modules remains to be discovered.

Soooo close. I tried what you suggested. 300 x 10 and managed to get through POST only to hit a TRAP error (?)

I love this DFI board--other boards would have had me popping the CMOS batery by now--the DFI just keeps resetting and resetting without a hitch.

However I was only able to get that far by gradually increasing each voltage to max--and even then it hung.

So I can pretty much hang that up for the moment.

Working on finding the best combo around 2750-2850 that will let me run the RAM as fast as possible.

That's saddening, but oh well :\\ At least you gave it a helluva try! I still love the project

I like the rig a lot. Not trying to be greedy--just doing my job here.

But anyway I really like the rig both in terms of performance and looks. I wanted to learn the ins and outs of AMD hardware and try some difrent boards and i find I like the DFI board a lot.

Too bad about DFI street and their troubles.

And I am sad that I am so ham fisted sometimes--breaking the fan, straining the fitting, somehow wiping out part of a great GFX card. Yep it seems like I am trying to pack awhole lot of modding and OCing into a short span of time.

But at least I'm enjoying the ride... and if I just can't deal with the little defects I have created in my fixing the fan then I will just get another Antec 900 and do it all over again--and try not to break it right at the end...LOL

Currently trying out 2770 ( 327 x 8.5) RAM @ 504

Haha- I guess a lot of lessons have been learned, most the hard way, but how else were you gonna learn them all? I have learned just as many as you have, which I guess makes us almost the same, but you definitely do much more than I have ever done...But both mods have been awesome, and definitely sources of knowledge! I will be referencing each the next time I do a custom-built case

Don't make me blush. Just having a good time. I know next to nothing about RAM tweaking...the DFI BIOS by Oskar WU is truly a masterpiece and requires a virtuoso to coax an amazing clock from it.

The Abit BIOS on ICE is whole nother kettle of fish...

The plan is to break 10K in 3DMark06 with one of these machines...even if I have to tear them apart and start all over again....
