With 4 dimms it runs in dual-channel mode, yes.

The ratio refers to the FSB:RAM ratio.

So if your FSB is 400 your RAM would be 800, which then gets you a dual data rate of 1600 MHz

If your FSB is 500, you get DDR3 2000 etc.

This is damn motherboard with all it's like perks and options is driving me and my buddy nuts. We can easily change the multiplier to 12x (QX9650) and increase the voltage and get 4Ghz overclock without touching anything else, but my buddy is feeling ripped off because his memory bus is running at 667Mhz (1334Mhz effective). He wants the the RAM to run at it's rated frequency (1800Mhz).

Did you change FSB Strap to Northbridge? Set it back to Auto and you should get all the available options for DRAM frequency. If 1800 or something close isn't among them you'll have to raise the FSB frequency and (possibly) drop the multiplier.

So, I've been playing around with my RE for a few days now, and am a little disappointed with (what seems to be) my computers limits..

Whenever I push my FSB up any higher I wind up with memory errors in Memtest86+ (increasing voltages don't seem to help, i've gone as far as 1.95 on my ram and 1.5 on the NB with no luck..). So I tried pushing the FSB up to 500, and keeping my ram at the following specs, and even with increase NB and ram voltages I freeze memtest86+ at 31% consistently (note, i do drop my cpu multi to 8.5, so it should be that either)..

I thought it might be a temp issue (my nb was running at 52c idle lol) as after a little research I learned that the thermal paste gunk that asus used was under all the standard cooling, so I pulled the whole mobo out, cleaned everything thoroughly, and applied as5. Temps are better now, NB is at 40ish idle. (and because i know your wondering, i'm running an air cooling set up, i replaced the stock coolers on the mobo with the bigger ones that came with it, and i'm using an antec 1200 case with all the stock fans traded out for the 110cfm slipstreams )

I've tried everything I can think of, and I was pretty sure I was just at the limit of my ram (with stock settings), but from my understanding, when I push the fsb up and keep the ram and cpu settings the same.. It should yield stable results unless my NB is a dud.. right?

anyways, any suggestions would be Much appreciated!


(usually Stable setup, right before i posted this i glanced over and saw more memory errors even under these settings, which have been fine every other time I ran it...):

Also on a strange note, one time I pushed my fsb up to 425, let my cpu stay at 10x multi, had my ram at 1900 with 9 9 9 27 timings, and cleared two cycles of memtest.. haven't been able to do that since (also, yes, i do turn it down to 2T timings whenever i try to over clock my ram)

You'll need to start experimenting with GTLs and skews.

Check here for some advice on your Mushkins. I realize it's with a quad, but it's a good place to start.

I'll give it a shot and let you know how it turns out, thanks for the reply (with my "stable setup (with slightly upped voltage on the ram), i just BSOD'd in vista and pulled two mem errors with memtest86+ x.x

zlojack

Be patient. People are slowly figuring out this board and all the tweaks. It's very finicky, but the final results can be awesome.

I'm still waiting for a few more parts to do my LC build so I can start to push this beast.

Finally got my Rampage Extreme.

I know, you have seen it before but it´s an awesome looking board.

But all that heatsink and heatpipe got to go for some better cooling thou.

I be back for more.

Ghostleader

Okey, now my board is ready for some action.

I use Enzotech heatsink for the mosfet and SB.

Koolance for the NB (It´s very flexible, I have used it on several boards and it do the jobb very well).

D-Tek Fuzion for the CPU with Xigmatek Crossbow backplate.

Hi guys first post, with a bit of a problem. Hope you guys can point me in the right direction...
well here goes...started to build my new system and took off the stock cooling to replace the thermal paste on the NB etc that Asus put on (or should i say throw on while watching porn )...Anyway I was obviously very careful at taking the screws out and lifting the heat sinks, however looking at the board I saw this....


The resistor has come away form the seating and I can't send it back because I've taken off the stock cooling. I would rather fix this if i can anyway and I have a friend who is gonna take a look at this but wondered if anyone had any thoughts on how best to resolve this issue....
