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

[FreedomEclipse]

Oh come on all you have to say in reply to my good news is to hawk your 3930K? lol. Actually as long as I don't have an issue with new CPU I'll be getting rid of my 3930K too but I may keep it just as a backup not sure the 3930K is worth much more than 150 bucks or so.

Well its not like im going to need my 3930k and what better place to peddle my wares than the X79 thread?

Is that 1680 overclockable? I hear there are some some xeons that sell for stupid prices if they do

 

[dalekdukesboy]

Yes, very OC'able which is why it went for about a grand or more just months ago if you go back in this very thread, only reason it's come down is Threadripper from AMD is very affordable and has even more cores and performs decently so finally the Intel stranglehold the last half decade is loosening and prices are hopefully headed towards sanity. First thing I'll do when I plop it in is put some screenies up showing you what it can do, should be way better than our 3930K's in every way.

Nice buy daledukesboy! That is the best X79 cpu ever made. I am looking forward to see some screenshots and benches.

 

[dalekdukesboy]

Thanks Peter! Here's my first screenie...my first attempt to boot I just put in some numbers but yeah, no idea if it is stable but I'm posting here and got video streaming on another website etc so it's at least stable enough to get to windows and run basic programs etc....CPU-Z misreports it as a 2690 but it does correctly say it has 8 cores etc but all good I have a feeling I'm going to have a ball with this.

I think my last post shows it's VERY overclockable lol. I don't know how far I can go and have it stable, but it's been running now for couple hours straight with video streaming online and couple programs running etc without a hitch. It looks like 48 is the top multiplier but that's pretty high considering I still have FSB to OC and most of these processors will deal with 125 strap pretty well.

Got nothing stable yet but also got my memory to boot at 2666 mhz which I got nowhere near with other Sandy bridge CPU's I was using, best I got to boot was 2500 or so and that was a battle. Been a while since I've monkeyed with any settings so will take me a while to dial this in and figure it out with new CPU but now that I think of it the 6 core cpu's I was using didn't even boot at 4.8 ghz or barely did and this thing did it first time I tried with 1.40 volts which granted wasn't even slightly stable but it booted to windows and so on.

Thats is a 8700k killer! If you have not reinstalled your OS you might need to reinstall chipset drivers, check device manager. Also check your BIOS settings so PCIe 3.0 gets activated.

Thanks, PCI-E 3.0 I already had with workaround for Sandy Bridge however chipset drivers I did not do so thanks for that advice might make a difference in stability I hadn't even thought of it truthfully. I will do that and play around with it a bit more and see what it can do but seems to be very capable at first glance.

I too heard about this patch to get PCI-Ex 3.0 working on SB chips. I never tried it myself because I heard it was quite risky and you could end up corrupting your windows installation because of it.

 

[dalekdukesboy]

I can tell you it worked fine, I did it and it showed as pci-E 3.0 with my 3930K actually several pages back in this thread we talked about it and showed screenies of it and me and couple others got it to work someone in thread here showed me how to do it.

 

[FreedomEclipse]

did you do a before and after benchmark to see how much performance you'd gained?

 

[dalekdukesboy]

No I didn't, I haven't had a card that would have satiated the bandwidth of 2.0 with a X16 slot I've read tests and until you get down to 2.0 x8 or less you hardly notice the difference with most cards.

I set memory down to 1333 mhz and stable at 4.7 ghz with 1.38 volts in bios running max mem with Intelburntest....very impressive!

Sorry for the double picture post I could fix it but it's good enough and kinda humorous not sure how I even did it lol, don't adjust your pc screens folks it's the exact same picture twice with different text on each, I meant to just add text but picture got into my added post.

So far, I'd agree! I almost got it to boot into windows @ 5.0 ghz, got it there easily @ 4.9 obviously not stable but still for only an AIO watercooler and 8 cores with hyperthreading enabled that's fast as hell. I've already got it stable @ 4.7 ghz with little effort, memory....that's a different story but mostly because my memory/X79 is finicky plus I haven't done memory tweaking since I updated bios and some of the settings are different, ugh. Also all the dumb templates the RIVE has are too far off what my memory can do so I have to manually tweak everything and only way to do that was to print out my old results and some comparable results from an IVY-E processor and I'll have hard copy in front of me to go through bios with and set it as needed. I tried to set it with what I remembered and wouldn't boot and AUTO gets it to boot @ 2400 mhz but bluescreens on me after a while in windows so it's close but not quite unfortunately....

Make sure you keep the USB 3.0 drivers up to date. The P9X79 uses external USB 3.0 controllers since X79 doesn't actually have on-PCH USB 3.0. Mine in fact has 3 independent controllers and they loved acting up without drivers and was the most finicky under Windows 7. Ironically, I've had the least number of issues with USB 3.0 on my board when running Ubuntu and before that Windows 10 seemed more stable (with respect to USB 3.0 drivers,) than Windows 7 was.

If the P9X79 Pro is like the deluxe, there are 3 controllers which means that it should be incredibly unlikely for all of them to fail simultaneously.

Yes, they are very finicky, some USB devices I have like cameras etc I can plug into my laptop and everything works and on my desktop it sees the device but fails to load it and recognize it properly. The USB on X79 definitely can be a bit wonky.

 

[dalekdukesboy]

So far so good, looks like even the memory I have was a good choice....does at least 2666 and CPU seems very willing so far!

For good comparison, here's my 4960X with 24/7 settings result

PS. Does Vcore Offset setting works for you at 125MHz BCLK (ie. downvolting @ Idle) ?
Change BCLK to 100.1MHz.

PP.S. NVidia PCI-e 3.0 patch : LINK.
Should work with any "C2" Sandy Bridge-E CPU.
I had problems with trying to run it on WIndows 10.

Nice, those are some great #'s for low voltage and tight timings with "only" 1600 mhz. Yeah I have to play around with it to figure out straps/settings etc it's a totally new beast to me after dealing with Sandy Bridge E I couldn't even get it to boot at 2666 and I don't use Vcore offset and I'm using Windows 7 62 bit lol.

 

[agent_x007]

Thanks.
I have all RAM slots populated with dual sided memory (8x 2GB), so doing pure high frequency is REALLY hard (read : Impossible)

Ah yes high density memory and all slots filled definitely not a winning combination for high speed that's for sure. But second best way to use your memory is what you did and keep timings tight as possible, I "only" have 16 gigs but I have no use for any more memory at this point I don't even use that much.

High density ?
I guess you missed that 2GB part... this should clear things up

This is lowest density at which point you can have 16GB of RAM in total if you are using 8 slot MB.
I have 128 chips of RAM in total (16 per DIMM, 8 DIMMs)

Yes I misread, I thought you had all 8 gig modules....so yes the density is low but....why use so many low density modules? I admit I just assumed if you populated all the slots you were going for max Gigs of memory.

 

[FreedomEclipse]

Still waiting for a cinebench run if you havent done it already

Coudn't get enough of Elpida BBSE
Also, they were cheap in 2016, and I needed 4x4GB DDR3 for my LGA 775 project (as seen in X3370/Pentium XE 955 scores from CInebench thread)

 

[dalekdukesboy]

Not even sure I have cinebench on here I think I had it and deleted it off my PC, if I don't I will just to see what this can do.

Also this must be a pretty tough piece of silicone....the tjmax on this thing is 95 degrees Celsius! I've never seen one that high most I've seen are in low 80's.

Where is everyone? Lol. Soon going to post some more benches stay tuned.

 

[johnspack]

I'm watching with interest... my 1650 v0 runs 4.7ghz 24/7, but probably couldn't do 2666 ram. Although if I could get my hands on some, I'd try....

 

[dalekdukesboy]

I don't have 2666 mhz ram either lol, but I binned a few sets of low voltage 1600 mhz RAM and so far it's gone up to 2800 mhz. I need to get a couple fans I've broken a few over last few months so I can't keep the CPU cool as I could before I'll put a few screenies of what I can do now and once I get fans and possibly bigger RAD do some after shots with better results.

Decent result but with slightly worse secondary timings and lower mhz and bclock the memory actually churns out better #'s so if I see that as constant trend I will just stick with 125 mhz bclock which I am posting now for comparison this is my best result thus far...


.

Highest CPU Overclock @ 4.7 ghz I got stable with memory just at stock settings

 

[dalekdukesboy]

Few little tweaks to secondary timings and I got all but the write speed over 70k mb/s! Pretty damn good I will keep playing around then get my butt in gear order few more fans to get air movement better in my case and couple big boys to slap on water cooler and see what I can get this thing to really do!
