X79 and/or rampage IV OC'ing thread for those of us still left....

[karakarga]

I have an Asus Rampage IV with i7-4960X processor. On the Ram slot's there are 4 piece of GSkill Trident 2666 Ram's. When I trigger, the mainboard automatically adjusts processor speed to 4000 MHz. Also increases BCLK to 125 MHz.

2666 / 2400 = 1. 1108333 if I multiply this result with original processor frequency 1.110833333 x 3600 = 4000 MHz so the reason. If I put on 2800 Rams, with same equation.
2800 / 2400 = 1.6666666 x 3600 MHz = 4200 MHz, the system boots I assume.


@PolRoger you have a 4930K processor, with same equation.

2800 / 2400 = 1.666666 x 3400 MHz = 3967 MHz when mainboard opens with Klevv modules. Can you verify this?

Here is my 4930K with XMP default on my GSkill Trident kit... The motherboard uses 125MHz strap with bclk bumped up to ~131.

@PolRoger

At some XMP frofiles, there are 2 options. My previous GSkill Trident 2400 XMP profile one was 2399, the other 2401 MHz, with slight Cas#, Ras# etc. differences.

Are there only one XMP profile visible for your 2800 Rams? I see 2 options 1T can be slower, setting 2T might increase speed a bit. But I already see Command Rate (CR) 2T. What about setting it to 1T?

Actually it must have to 3966.1 I wonder why lower than that 2799.6 / 2400 = 3966.1 - 3936.78 = 29.32 MHz lower! Bus speed have to be 132.2 MHz.

For bare 4000 MHz, 133.3 bus speed can be chosen. (Well sometimes, everything not goes straight!) Maybe the bios gets the equation by this....





By the way, I have currently installed 8 piece of 4 gigabyte sized Registered ECC modules. YES Rampage IV can use Registered ECC modules, if you have a Xeon processor.

BUT, does not recognize 8 gigabyte sized single row modules. Do not try to install 8 gigabyte single row ones!

Note: I did not tried other types. Example: double row 8GB, 16GB single and/or double row sizes!

I haven't run these kits very much on this platform but they will run 1T. I have two different binned GSkill kits both produced in the same month/year with the same ic: Hynix CFR.

Here is some testing from today at 2700 C11:

 

[agent_x007]

CR1T should be faster on the same frequency.
CR2T setting is required for higher frequency OC (1T isn't stable for anything above ~1600MHz for my setup).
Asus X79 boards have 128GB RAM support (at least from latest beta BIOS).
Why they can't support 8GB/side memory ?

This configuration is very close to my current setup, I have 8 core vs 6 but IVY as well and memory is at 2800 mhz vs 2700 with almost identical memory timings. My old memory would not do over 2500 mhz 1t, but like your memory here my newer memory currently in system does fine 1t at 2800 mhz but some of the secondary/tertiary timings are looser. Your Row Refresh timings are tighter than mine I can't do 214 at 2800 mhz though. I will stress test mine to see if I can get it stable I'm still working with settings to get it stable.

 

[PolRoger]

I believe your Klevv kit modules are (1 Rank 8 banks ~Hynix MFR?) While my GSkill modules are (2 Ranks 16 banks ~Hynix CFR). The higher density chips on your kit vs. mine will require higher/looser tRFC settings.

AIDA's spd setting/tab will show info for your kit as well. I only have a single set of Team DDR3 (2x4GB) with single sided modules so I can't run them on this platform in quad channel just dual channel.


Here is XMP on my Teem kit (1R 8B ~Hynix MFR) at 2700 also my Crucial DDR4 kit (2R 16B) at 2800 which has similar size/density ic:

Teem Xtreeme

[dalekdukesboy]

The reviewer said he received two kits and tested together...

"Just like our other KLevv samples, we were sent two 8GB kits, and we will be testing these in 16GB of density."

Label on the stick also shows 4GBx2.

I sometimes run two matching 2x4GB kits in quad mode or even as dual channel ( with full dimm/bank populated) and I also have some 4x4GB kits.

The label on your sticks should indicate how it was originally sold by the manufacturer. Anyways I don't recall/remember seeing much in the way of high speed DDR3 kits released in a 2x8GB configuration.

Good info. I admit I've done a lot of memory overclocking starting even before ddr1 and I've read a bit on the theory/explanation of memory but specifics regarding timings and ranks/banks I only have a vague grasp of so I appreciate you posting info plus where to find it in AIDA I've poked around through most of the screens but often if you don't realize where to go there's a lot of info there you can miss out on if you don't know where to find it...I'm playing around right now with the Klevv's and trying to find good timings for it.

It's admittedly frustrating because X79 is a bitch when it comes to memory settings and very small changes can make huge difference from a stable setup to one that crashes in windows randomly or won't pass a stress test even if it's able to keep from crashing doing light tasks....

MOST frustrating part is I've seen as high as 80,000 mb/s read time and lower 70,000 mb/s on copy/write times but finding stability doing so has been challenging. However I know it's capable because I've done it. I can fairly easily get low/mid 60,000 mb/s on this memory stable but so far when I get the really high bandwidth it's not been cooperating in the stability department.

So you are correct this memory is 1 rank, 8 banks. Here's the actual info from AIDA.

A quick LinX test on my setup... I noticed that "daledukesboy" and "agent_x007" are getting ~200+Gflops while I'm at ~175+Gflops is that due to the two extra cores on the Xeon cpu that you all are running?

 

[kastriot]

I just saw prices for 1680 v2 on ebay, those guys are mentaly ill or living in past.

To answer Pol yes the 2 extra cores I'm sure is the difference especially considering you're running processor a bit faster than us, also what are the prices on ebay that are so absurd Kastriot? To put perspective 375 American dollars is what I paid for mine 6 months ago and not sure what 400 is overseas but that sounds a bit high depending on the exchange rate.

Also just as a note to all my 2 + year old mobo just croaked I was having issues with stress tests and thought it was dead couple months ago but I think that was beginning of the issue and then it just became finicky and shut down during stress or caused windows errors and restarted etc but I believe the VRMS were just too hot too often even though I had fans on most of them but couldn't get every spot on board so guy before me used board for several years so I think it just burned out. Anyway I just ordered the Rampage Black edition on ebay and with luck I may get it today so over last few days so I should have better board and hopefully better bios so should be interesting to see how it does compared to my regular rampage boards I've had. Also best thing is the heatsinks are over the VRMS and other spots that they somewhat neglected on regular edition board so hopefully that will help stability and longevity of the board! More to come once I get everything put back together in case.

 

[mouacyk]

305 usd for mine months ago. Seller listed at 375 but accepted the lower offer. My mobo croaked this month too. Eps connector melted on seasonic cable.

Waiting 1 month for a much better board.

 

[agent_x007]

I got mine for 369 Euro from Germany, around one and half months ago (shipping was WAY lower for me vs. US bought one + I got 1Y warranty on it ).
My MB on the other hand survived i7 3820 @ 4,6GHz for 5 years, 4960X at 4,5GHz for 9 months, and now I'm with 1680 v2 at 4,3GHz

EDIT : @PolRoger Here's my 4,6GHz score for 4960X I own (in IBT Very High instead of LinX though...) :

@Agent

I've noticed that you run offset with your dimm voltages: Channels AB vs CD? Any reason as to why you don't run them balanced? Like both at 1.625v or both at 1.65v??

 

[agent_x007]

I do use four different sets of Dual Channel memory you know (ie. NOT a two Quad Channel sets), also - one "memory bank" is before CPU cooler, while the other one is after it (operating temps are different).
Finally, according to software readings "C+D" is aways behind "A+B" by around .02V, I try to compensate for that.

[dalekdukesboy]

Dalekdukesboy is technically getting 0 or whatever this cheap laptop with dual core i5 and slow ddr 4 would get which would be almost humorous to post but not even worth downloading and activating aida64 to test on this. I had hoped the overnight estimate of UPS to get board here was actually right but, no surprise it's not even updated to show it's en route nevermind that it's here and day is over thanks UPS for getting my hopes pointlessly up! Anyhow nice results on tight timings I never could get cas 7 or 8 at all or at any speed worth mentioning on my board..hoping I'll be blessed and the black version does even better whenever I actually get it.

Shame I was looking for someone with a similar system as my previous to run a few benches for me for the sake of curiosity

OH YEAH? WELL TAKE THIS BITCHES!

You mentioned Dalekdukesboys great scores with temporarily defunct X79....but I was wrong about scoring 0 this laptop is just SOOO kickass!
