Wow, so you've been running a 150W TDP CPU x2 in a Z7S WS and your VRM is yet to blow. From everything I've read that's a miracle. I guess you must have a fan blowing over the VRM section, are lucky...

Thanks for your offer though I already also have 8GB of Micron PC2-6400 FB-DIMM's for quad channel mode. I have a OCZ XTC memory dual fan cooler that's quiet should I decide to leave the HyperX...

Thanks for replying.

Yes, I hear these Elpida IC's in the HyperX FB-DIMM's are the culprits. I do have four of them but was thinking I could use their heatsinks on other FB-DIMM's. The only issue...

Hi all,

Can someone here please confirm whether this board despite the latest BIOS (0401 or 0501) still doesn't allow changing the RAM timings from within the BIOS? I'm just trying to figure out...

I vote for the Noctua NH-D14, not just because of its cooling prowess but also mounting mechanism. Just make sure it fits in your case.

Okay, I see, thanks. I was applying the patch then turning the PC off to install the 2nd card. Unfortunately I sold the second card now so can't try again. If this is the only thing I was missing...

Well, in Windows 7 with UAC turned disabled and SLI Patch 1.0 run as Administrator the patch installs fine. The problems start as soon as I physically install the 2nd GTS250 in PCI-E x16 slot #2....

I see, thanks. In that case it's problematic but what's surprising is that MSI don't see this as a way of affecting their RMA rate on this board. Luckily it's something they can fix in software, and...

Guys, correct me if I'm wrong but wasn't Asus first to introduce this back in the original Rampage Extreme? It too has a BIOS option for EPU-II Phase Control of Auto or Full.

I don't recall anyone...

Check the ES Q spec number but I'm pretty sure it will be an E0.

If you get it please report back if it's unlocked.

I have an X9750 (which is a QX9750 except Intel called it differently) ES...

I was also trying a similar configuration (only different is GTS250 instead of your 8800GTS's) and I think the problem is somehow related to the SLI certificate. From the post here on how to enable...

Well guys. I installed the Adata 1600x, setup the BIOS how Ghostleader did his in the other forum (from the BIOS screenshots) and memory read in AID64 is now ~10.7GB/s (up from 10.2GB/s), write is...

Thanks for opting to reply. Correct. At this moment in time I'm restricted to CAS9 DDR3 and with the 200 strap I can run tRD = 6 fully stable with a VNB of 1.44V.

I wasn't aware CAS had anything...

Hmm. Sadly I've not had much luck with Asus technical support. They've always given out the impression that they either don't know what they're talking about (instead just copying and pasting...

Thanks for that. Correct me if I'm wrong but changing the MCH delay in Bar_Edit is only a runtime temporary fix right? It always gets reset by the BIOS each time the system bootstraps and thus needs...

Hi, I tried 200, 333, 266 and 400 like you posted over in the other forums but it's always a black boost screen, regardless whether phases are enabled or disabled. As I wrote above I find this...

True, but here's also achieved the same with 2x2GB if you look at the post below and scroll down a bit, just above where he's pasted screenshots of the BIOS and where it states "Moderate OC...

Theoretically the X48 MCH shouldn't be stressed at 400MHz FSB but in practice it's the tRD that makes or breaks stability as I've had to increase VNB to 1.44V in the BIOS at tRD = 5, AI Transaction...

Hmmm, maybe it is the dual Vs Quad issue all along. Sadly I don't have a dual to test it out with.

Here's the post I'm referring to above over at Overclock.net forums:

Thanks for that. So that's 0-1 proving tRD = 5 at 400MHz FSB is too tight, even with only two DIMM's.

It's strange in a way though because back in the days I had a Maximum Formula with Rampage...

Hi all,

I've revived a Rampage Extreme X48 chipset board and I just want to see what you guys have to say in terms of setting tRD at 5 at an base FSB of 400MHz (1600MHz effective).

From what I...

Thanks again. Will investigate the matter. Oh how I love small pins :)

I'll redo it with a 2B pencil once I get one. The pins on the ADP3198 are smaller and closer together than on the ADP3181 so it's somewhat tricky.

Just an update to say I followed my above line of contemplation and it works on the ADP3198, just the pins are different to the ADP3181.

Tested it with a rare Q650 ES CPU at 3.73GHz. Prior to the...
