UnOfficial Asus Rampage II Extreme Thread

[dejanh]

Right now with my moderate overclock i'm at 4.2 with turbo and HT. CPU is set to 1.43v with the rest of the voltages set to auto except RAM.

1. Running my Ram Speeds at 1603mhz, 1.65v, 1.36v VTT, 8-8-8-20-1N
2. No, Overclock is set to Manuel
3. No, I have Triple Channel according to CPU-Z.
4. No I do not have the cold boot issue.

Why would you even want to load up the XMP Profile, What about the ROG profile? Does it do the same thing?

I've heard on the Asus forums people have been having luck lowering there Vdimm voltage to 1.55 instead of 1.65. Lay off of your OC'd RAM settings to test this theory out.
Run it all manuel. with 8-8-8-24-2N with 1.55v and see if the problem persist.

I've also heard of people reseating there VTT Card.

Well, I guess you were right. After I turned off the X.M.P. profile and did all of the OC settings manually the VTT does not crap out on me, or it has not done it yet. This is very (no wait, extremely) strange as X.M.P. sets the exact same settings as what I have entered in manually. It must not be doing the exact same thing then...it must be doing something else. I will keep you posted on the results as time goes a bit too. I am still running tests.

Now, after I did this I changed my OC settings to 20x200MHz flat, 1600MHz DRAM with 8-8-8-24-2T timings (default), 1.424V core voltage (high voltage chip unfortunately), but get this, I was able to lower the VTT to 1.3V (I can go lower, down to 1.25V - 1.27V but I do not want to), and DRAM voltage down to 1.5V (lowest available setting)

So far 30mins stable with 4-cores/8-threads at 100% constant load...

Oh and temps, peak out at 75C on all cores on air. WTF? Must be the lower VTT (QPI/DRAM).

Something is majorly screwed up on this board. The more I use it the more confused I am. I'm thinking that it has major issues with DRAM now...not sure any more...maybe it is the low voltage DRAM parts that are problematic? It is the first time around these are being done...hmm

I've also noticed that all of you guys have the 90-MIB6L0-G0EAY00Z part. Asus sent me this part as an RMA as well and I found it way worse than my current board. However, my part is (get this) newer it seems and it is 90-MIB6L0-G0EAY10Z. I'm thinking maybe to stop my 2nd RMA now. I don't think there is a point. Maybe everything is working as intended and memory is the culprit for it all? I almost want to go pick up some Mushkin sticks (I never had problems with Mushkin in any board for 12 years) and see whether that changes anything...

Edit: Test crashed about 50 minutes in. I upped the voltage now to 1.432V on the core. This should be sufficient for 24/7.

Just messed up. That's all I have to say. I think I will get Asus to pick up the board now and tell them to send me an RMA only if they have a part number different than the two we listed here. Otherwise, I do not care to replace it now. Maybe when it's close to 1 year from now and all of the initial batches have gone through the system.
