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

Just set BCLK to 125.1MHz.

Exactly, I wasn't sure what the setting did till I changed it and then I looked it up to see exactly what the technical explanation of it was.

This thing literally can do 2666 mhz memory and 4.5 ghz in it's sleep! Totally different beast at 4.6....fact that it runs so cool at 4.5ghz obviously is helping me lower voltage even less than I used to use before with lesser cooler setups, hottest core barely broke 70 degrees. I'm not sure I ever got it under 1.3 volts for 4.4 + before and certainly not 4.5. So I think at higher mhz it may be as likely the board has the problem and gets a bit hot on vrms etc, I do have one good fan there but in past I've had 2 or even 3 fans with one on southbridge and or the heatsink on back of board where monitor/mouse etc all plug in.

1.408 load voltage and 2666 CAS 11 and 4.62 ghz so because I'm a bit anal retentive I'm posting this to record it but without even going back I think that's almost exactly what the old "Black" board did but none of the weird shutoffs etc or a power supply frying plugs lol, oh and the bad USB cord to monitor, that was a new one on me but since I replaced that cord a whole bunch of issues with video playback and even stability/restarts etc have vanished, amazing how much every little component matters in a build to get it all working properly.
 
Hey all long time user of an Asus rampage iv black edition motherboard with 4930k cpu, just snagged a 1680v2 for $200usd, currently I'm on 701 bios will that play well with my incoming 1680v2? Cheers
 
This is a neat thread; I'm running a e5-1650v2 I bought for $40, and it overclocks about the same as my 3930k did.

Both processors seem to hit a thermal wall about 4.6GHz, where the temp goes way up; at 4.5GHz I'm hitting ~72°C, and at 4.6 it goes over 80.

The 3930k drew ~250W at 5GHz, after I mistyped in the settings, lol. It booted windows before I noticed, and hit 90C before I shut it down.

I'm amazed this Sabertoothx79 can deliver that much power, lol.

I'm still having problems getting the voltage settings correct on this processor; during heavy gaming it throws a 124 BSOD, which is CPU voltage, pretty much.

The Xeon doesn't like to run 2400 memory, but it's not really rated for that.

I also bought a 10/20 core e5-2650, but it will not overclock at all, really. :) I used to do Bclk Oc's on older processors, but these don't really do that.
Any advice about overclocking it would be appreciated.

I'm amazed the 1680 is down as cheap as it is now; will have to get one. :)
 
The person has them for 240usd on ebay but I offered 200 and he accepted I'm in New Zealand so that's 360 NZD including shipping, should be here next week with luck

Welcome to thread! Also that's a very good deal on 1680 even now as they finally are coming down in price.

Thanks and yes I created thread a few years ago when I noticed there were like zero other threads for X79 even at that time. Welcome! Yeah the 1680 has no problems running 2400 + on memory so if that matters to you definitely is great for that plus it's 8 cores and overclocks well. The 2600 series can't OC for crap thanks to locked multiplier and from what I've heard do not do high mhz on memory either so that's just how they were built.

Nice, I'm sure you will have great results with it to post here.

Will do! Using a Corsair 110i for cooling I'll just be happy with 43ghz oc, my ram only Gskill 2133mhz so should be fine.
 
Hi guys, I wanna join in on some x79 fun!
Just got a asus sabretooth x79 mobo (like literally anything x79 in my area is scarce) .20190525_230930.jpg20190525_230833.jpg
Planning on getting some high core xeon, last on the list of supported cpus xeon e5 2697 v2 a 12 core 24 thread is actually available on aliexpress (as much as its so muh cheaper, im not sure if its a good deal), thinking on getting one of those. Any recommendations? Some bang for buck options? I will prolly crunch with this system but being able to game on it would be nice too.
Also ram-wise can I populate all slots? Does it make difference? I'd prefer to do so. Also what about clocks? Should I aim for more than 1600mhz?

I have a similar model Corsair that I was using for this rig and it did decent job even with the 8 cores up to 4.4 almost 4.5 ghz mine is a 280 mm rad I believe forgot model but called "extreme" might be 110 as well.

I found I could not get a e5-26xx chip to overclock hardly at all; they're multiplier locked, and the FSB on my sabertooth only goes up to 103MHz before it crashes, with whatever processor I've used.
I may be doing something wrong, but that's how it worked for me. :)
On the good side, the power section of that board is good for 250W, for at least as long as it takes to open windows, see it's running too fast, and shut it down.
:rofl:
My 3930k ran 5.1GHz for about 2 minutes, with no lasting damage. (51x multiplier, 100fsb... and 1.45V. it hit 90°C.)
I think it limited at 250, but I never tried that again.

I bought a e5-1650 6 core; it overclocks about like my 3930k did, with a more than 10°C cooler operating temperature.
The only difference I've found is that the Xeon will not run my 2400 memory at 2400; 1866 seems to be it.

I'd buy a 1680, for the extra cores, personally. if you want to game with it, those OC well.
If you want raw cores, there's some Unicorn processors HP and Dell made out there.
I saw one that was 32 cores, and was over $40k. In 2011v2 socket.

I'm running 4 sticks of HyperX 8GB; Ive never used over ~18GB of ram, and that was running a benchmark in Blender.

The 2650 v2 10/20 core was faster in the Blender benchmark, but Way too slow for Crysis.

Crysis loves a video card with 8GB, btw. :)
My RX480 is every bit as fast as 2 7970's in crossfire, and only draws 150W.
I'm only playing 1920x1200, tho. No 4k. :D
 
Hope to see some more info from newbies here if/when you have it screenshots etc :).
 
Been busy havent had much time to tinker with my X79 but I actually managed to sacrifice some sleep in order to test it!
Obviously its used hardware so i had to check if it even boots.
It does, suprisingly temps were great even though I mounted that hyper212x (I bought it sepecifically for this)
with plastic sticker on omg haha.
I got this Xeon e5 2609 for like $15.

Regardless, now i need a PSU for this rig and some decent quad channel ram stick set.
Also thinking really hard about this cpu:
Might be main crunching on this rig actually and its only 50 bucks for a 10C 20T

BTW: I have some real concerns about the fact that my 7970 covers up southbridge fan, will that be okay?

If you're happy with that clock speed, it's a cool processor. :)

I can deal with 6/12 cores at 4600MHz much better; the 10/20 cores at 2400MHz won't really run games well.

As mentioned above, the 1680 8/16 core chips are ~$200, and will OC as well as the 1650 will.

Blender or Handbrake really doesn't seem to care about raw speed, however, they want cores. :)

Here a shot of my system running 4300MHz; I cranked it back a bit because it was crashing in FC4 last night; it wants a bit more voltage, I think.

 
Lovely feedback gentleman and interesting systems! Anyway since you did validation I haven't done that in a while so this is a shot of my current stable OC and setup.

Hi all! I'm new here and recently purchased an 1680V2 to replace my 1650v2 (I had a 3930K before).
Tried to overclock the 8 core beast, but I'm a bit concerned by the amount of heat it generates: I'm running 4.4Ghz @1.30V and the cores easily get to 90 degrees after a few minutes of LinX... (similar temps with 1650V2 as well actually Oced at 4.4Ghx @1.3v)
The cpu is cooled by an AIO Corsair H115i.
The board is an Asus P9X79 Deluxe.

Can you help? Is there a specific setting in BIOS that heats so much the cpu or...?

I run 1680v2 at 4.5GHz with 1.312v and reach 68C (compiling linux software source code) max with 240mm + 120mm custom water cooling with EK Supremacy block. Under LinX stress testing, I think I reached low 80's.

Have you tried a CPU test in 3D Mark or something? I'm sure the temps in LinX are a lot higher than normal, so if you hit 90C in LinX, then you're looking possibly around 70C in heavy loads in game etc. If your concerned, try running CineBench R15/R20 to see what it hits. What sort of temps are you getting at idle?

Well idle temps are 5 degrees above ambient temperature, so around 28/30 degrees.
Im actually playing far cry 5 at the moment and during game I see temps around 65/70 degrees
 
Just being curious now, but have you set the vcore to a specific number or is it set to Auto? Auto settings generally push more vcore through the CPU which causes the higher temps...

That isn't a bad AIO but coming from a guy who had same AIO (still have it in spare parts tote) you are getting relatively normal temps for that cpu when you push it to that point. 4.5 or even 4.45 ghz was about all I could do without cpu burning up with that AIO UNLESS I modded it with 4 high cfm fans. So if you aren't too worried about noise I can recommend a few fans that are not "screamers" like the wicked high cfm Delta fans but are very good performing fans which will drop your temps significantly if you put 2 or 4 (push/pull) configuration on that cpu. Also I see when you play a fairly demanding game like Far Cry 5 it stays pretty cool 70 degrees or less so that's perfectly fine.

I'd suggest going back through this thread and seeing my progress with my cpu as I changed the cooling method because if you are using totally stock Corsair 115i your temps seem very normal for pushing 8 cores of ivy-e to 4.5 ghz and using linx which is very stressful program. Also you can peruse through what other members here have (like next reply I quoted) and see how they do with same processor with similar boards and their own cooling solutions. I have found comparing all our results very handy and reassuring as I often wonder like you if "my temps are normal?" or my cpu sucks or I'm doing something wrong with settings etc as you suggested.

Also....WELCOME!!! Would have said that earlier but wanted to jump right in and offer my 2 cents on this.

I run 1680v2 at 4.5GHz with 1.312v and reach 68C (compiling linux software source code) max with 240mm + 120mm custom water cooling with EK Supremacy block. Under LinX stress testing, I think I reached low 80's.

This. So as I was saying you need a whole lotta cooling to keep this cpu cool 4.5 ghz +, Mouacyk has custom loop and gets fairly close to what you get for temps (80's) with only 100 mhz extra speed and hair more voltage than you. Also Mouacyk didn't mention fans he's using but I believe he did in prior posts. Also Mouacyk, I see the EK block and rads you use but what pump are you using? That also is a big deal, corsair pumps are decent but they aren't super high water flow either. I have to put finishing touches on my rig and I'll show you the frankenmonster solution I have to cool this cpu and it's 2 big rads on an AIO with a fairly high volume pump. I don't have all specs in front of me and also I want to use this post as motivation to "clean up" my rig and put it together because it's a sad looking almost semi-open bench looking affair because I've been in/out of it so much I never bothered to put it all back in the box lol.

Thanks all for your participation here and keeping my/our thread going so long! Long live X79.
 
i have a D5 pump running constant 3700rpm and GT-AP fans around 1700rpm.

This thing is supposed to run hot. There's 25MB of power-hungry L3 cache to drive as well, vs 15MB of the next step down.

Hi there, I set the Vcore to Offset with a +0.50v as Offset value (I like the Vcore and the clock to drop when system is idling :) )

Thanks for that! I feel a little more ok about my temps now.
I'm not fully sure I'll change the fans on the AIO as I'm a bit concerned by the noise increase. After all, anything around 4.2 / 4.5 Ghz for a daily use and some gaming are more than enough for my needs
thanks for your quick help!
Should I tweak the BIOS some more I'll write again after reading again all the discussion

By the way I'm very surprised how a years old CPU is still able to run everything perfectly!
 
Hi there, I set the Vcore to Offset with a +0.50v as Offset value (I like the Vcore and the clock to drop when system is idling :) )

I normally stick with a fixed vcore, I've never got to hang with the offset as such and always feared putting too much in.. So I'm thinking that 0.50v sounds like a lot. Do you have a CPU-Z of it under load just so we can see what voltage it's getting fed at all please?

Well with that setting under full load I'm below 1.3v
I'll try to post a pic later today

Edit: hmmm can it be its actually a 0.05v ?
I'll confirm later today
 
Judging by the 1.3vcore I'm guessing it's 0.05v or something around that :) If the stock vcore for the CPU was 1v, with 0.5V offset, I think thats 1.5vcore?? I stick with fixed then you can't really go wrong :) Either way, I think you're doing fine and have nothing to worry about :)
