***Asus Rampage III Extreme Owners Thread***

i can hit 1600 CL6 @ 6-8-6-21-72 T1 just fine... but anything over the stock 1866 just gives me problem after problem. at first it thought it was uncore issues but my cpu boots just fine even when i force uncore to 4200... but when it comes to the memory it just doesn't care to work with me.

Take the CAS 6 DDR3-1600 option. The CAS time is simply too slow at CAS 10/11 DDR3-2000 to compete with that on any level - the bandwidth won't make up for it.

Since you guys are talking about memory, let me ask you this. Would it be better for me to run my ram at 8-8-8-24 / 2000 or 7-7-7-22 / 1900? It's stable either way with my vtt at 1.3v.

use aida64 benchmark and check the result yourself.

i don't mean to be rude... self help is good...left hand or right hand

7-7-7-22 @ DD3-1900 is faster on every read transfer than 8-8-8-22 @ DDR3-2000.

Beautifully said. I agree and encourage the same

Not rude at all. Thanks, I'll download it.

7-7-7-22 @ DD3-1900 is faster on every read transfer than 8-8-8-22 @ DDR3-2000.

Awesome!

[skuldarin]

so i've got 1700 going at 6-8-6-23-72 T1 with RTL's at 60-62-63

i was trying for 1800 but as soon as i start hitting the 1765-1780 range BIOS starts to just freeze. any ideas on that?

EDIT: here'sthe bench results on this setup:

[Sylver123]

Hi

Can someone please let me know whether these memory speed scores are prittay good for Corsair Dominator GT 6GB DDR3 PC3-16000C8 2000MHz
or not and if there's anything else I can do that might improve the speed a bit more.

Thanks.

[KILLER_K]

Nvm......

i'd say it's not bad when i compare it to my results...

your read is about 700mb/s faster but my write and copy are faster...


in this case:

1700mhz @ 6-8-6-23-72 T1 is faster than 1950mhz @ 7-7-7-18-(x) T1 for write / copy. roughly the same for read with favoritism to 1950 CL7.

Which is more important, read, write or copy?

I`m sure I have read the lower your memory latency is the better.

[skuldarin]

Yes, lower is better. In your case after seeing the differences id go to cas6 and then get your highest stable speed then and bench. You'd probably blow my results out of the water sense your sticks are cl8 to begin with, mine start at cl9 and like stagered timings.

What's the difference between the Rampage III Extreme and the Rampage III Black Edition? Anything significant?

[McDown]

My GT's suck big time. I see people with the same RAM (CMT6GX3M3A2000C8 ) showing some nice results. Mine doesn't even post with CR 1T or CL7 after ~1850mhz
Maybe bad revision (Week 23/2010)

Here's my "sweet spot" for 24/7

Mainly the plug-in NIC and Audio card (aka Thunderbolt) plus a couple of hardware changes to help attain higher stable QPI frequencies for benchmarking.

That would be nice, would have expected better from the Rampage III Extreme though. My Rampage 2 Extreme could do better BCLK and higher QPI Data Link rate. IMO you guys should stop basking in the reflected glory of the one good Rampage Extreme you made (the original X48 board) and actually produce excellent board worth their price tag and that are a cut above the competition. Nothing could touch the original X48 REX and its looked back on as the best X48 made, but the R2E and the R3E can be easily beaten by other boards.

nah you're not the only one. like i stated earlier, mine wont go higher than the stock 1866 without having issues. have you tried stagered settings?

i've got 1800 @ 6-9-6-22-88 T1 and it's blazing pretty nicely

You could probably gain some bandwidth by lowering a few of your timings.
Here are some settings for you to shoot for:

Thanks. I also notice there is no PCI slot available on the Rampage III Black. I wonder why they did that.

So everything in this thread would apply then to the Rampage III Black then?

[Raja@ASUS]

Thanks. I also notice there is no PCI slot available on the Rampage III Black. I wonder why they did that.

The Thunderbolt card uses a PCIe slot. Most decent add-in peripheral cards are now available in PCIe flavor, so it makes sense to utilize the tech exclusively on a flagship product.

Alright, is there any of the recent updated BIOS that has tRL's yet other than the beta 0003?

seems almost all the BSOD's i'm getting while trying to test for stability all have to do hardware aurguments. i keep getting stop code 024, 0F4, 03E and every once in a while 01A. i have a suspicion that it may be do to the beta BIOS + not having the updated raid controller. so does any of the more recent BIOS with the newer raid contolers have the tRL's put in it... or is ASUS still slacking about on that key point still?

Try BIOS 1301. The tRL fucntion was added to BIOS 003 at my behest as an experiment to see if manual offsets were required to prevent memory channels dropping out. By default the tRL values are auto set and should default to the correct value without the need for user intervention.

1301 adds a memory rechcheck function at boot time to retrain clock skews. If everything works as it should, tRL won't be needed.

awesome thanks

tRL's have been kinda useful, not a HUGE difference but it did help on a few settings. going over +3 or -3 would normally result in a complete drop of whatever channel it was set to, but it still helped on my channel B drop out issues.

Those dropout issues could also have been due to insufficient training duration or pushing the memory too far. Try 1301 with speeds your memory and IMC is capable of running and see how you get on.
