THE Asus Rampage Formula/Maximus Formula/P5E Deluxe/P5E Thread - Page 30

post #291 of 2014
Updated with 0219 RAMPAGE, although I see little actual difference in my settings from 0207 besides increased TRC options. I still need 1.425Vcore for a stable 3.6GHz, where with the Maximus BIOS I only needed 1.400V. So much for lower voltage on my CPU. At least I have been able to drop my VNB by 0.15V, and may have some room to go down more.

The real difference I'm seeing is in the memory setting selections. Wow. I'm going to be spending a lot of time tweaking my subtimings I can tell.

Preliminary findings @ 3.6GHz DDR800 4-4-4-12 (untweaked subtimings)

Maximus formula BIOS 0907; 2x1Gb DDR800 3-3-3-8 1T tweaked subtimings gave me about 8900MB/s bandwidth and rockin latency of about 49ns. 4-4-4-12 2T timings gave me 8400Mb/s 57ns latency. Default PL was 7.

My 2x1Gb RAM died during conversion, so I stuck in 2x2Gb DDR800 5-5-5-18 2T and tightened down the primary timings to 4-4-4-12.

BIOS 0207- Really crappy bandwidth only 6400MB/s. Outrageous latency of 79.9ns. Noted that I was able to increase the performance level, whereas on the Maximus BIOS it would not even post with the PL enabled.

BIOS 0219- Much, much better. Bandwidth increased to 8100Mb/s, latency decreased to 60.8ns. PL is disabled (12 by default). These numbers come in line with what my 2x1Gb sticks ran at DDR800 4-4-4-12 2T I think with just a bit of tweaking I can have nearly the bandwidth and latency of what my 2x1Gb sticks gave.

Agreed. I am going to have to tweak the ram a bit.

The Article at AnandTech titled, "ASUS ROG Rampage Formula: Why we were wrong about the Intel X48", is a must read. The article explains all the additional bios memory settings and explains the science/match behind them.

That is an excellent article, indeed. The tRD makes this flash well worth it, IMHO. Last night, for the first time ever I got over 1GB/s on R/W/C! These are almost DDR3 speeds.

Oh & keeping in mind this is 4x1.

Turns out my system was not 100% stable. Perhaps my problem was not Vcore at all, but VNB instead. I bumped my VNB up to 1.55V and am testing now. This is still a major improvement, with the Maximus BIOS, I absolutely needed >1.6VNB just to post, where even with 1.49VNB on the rampage BIOS yields a mostly stable system- OCCT, Prime95, ORTHOS, MEMTEST86, and Sandra passed, but I got a BSOD while folding.

I think from here on in I could probably stick to folding as my stability check- it seems to be the pickiest software I run.

Pretty similar to how I was calculating for subtimings- AnandTech really drives home the point of how tight timings CAN be of a huge benefit to Intel systems, like I've been trying to preach to the folding team. I'll take 45ns latency @ DDR 800 over 70ns latency @DDR 1150 any day- while benchmarks may yield higher bandwidth to DDR1150, I absolutely see a real workd difference between the two and better performance with less bandwidth.

Hmm. Still having issues. I've eliminated voltage as the problem- I've gone both up and down to the extremes. Could be DRAM static read control- I've tried enabled and auto, testing disabled now.

Other than that, there are only 2 possibilities:
1) The Rampage BIOS is not stable on the Maximus I have. I highly doubt it, there are just too many folks at XS running it no problem.

2) My new XMS modules are not so hot. I think that my stability issues may be there, although none of my benchmark utilities catch any errors.

I still have a few days left to return my RAM to Frys, so I'm going to tweak it out and see what happens, although I think I'll end up exchanging it for something else even if I get it stable.

EDIT: DRAM static read isn't it. Raising tREF to 45 and up.

How is the chipset cooler on this board?

Is there much of a need for aftermarket cooling?

Thanks again Ericeod for recommending this board, I pickup my board tomorrow, and oddly enough my old board (P5N32-E) just died.

The stock IHS is pretty decent- perhaps the addition of a fan would help, but stock w/AS5 reseat works for me.

Replaced that Corsair XMS with 2x2Gb Patriot LLK sticks. We'll see how things roll.
