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

[lexluthermiester]

Well, wonder how many x79 mobos there are still out there. Mine just died and I'm kinda f'd. I also have an 1680 v2 I could part with. Typing this on my only computer, a mobile core 2 pentium dual core. Holy crap it's slow! Anyone have any ideas?

The Machinist brand has been solid for me. This is one I've bought a few of recently.

It takes DDR3-ECC-Reg'd DIMMs, which are dead cheap right now. It also takes normal DDR3.

I see them every once in a while on Offerup and Craigslist. Someone that's about 50 miles for my location has an X79-Deluxe, and there's someone selling a partial system with a RIVE board.
Yes, ebay auctions is also decent if you know how to work ebay.

So today I got to push my 2697 V2 over 4Ghz

I always ran "CPU Strap" setting on Auto and didn't think much of it. But during some troubleshooting I set it to 100mhz, and oh boi. 114.100 BCLK was no longer the limit
In fact it went all the way up to 114.600 at just +0.35 offset voltage... ending at 4010mhz max boost frequency. Never thought I'm gonna get above magic 4ghz barrier using that 2697 but here we are

Of course I immediately got to benchmarking and new limit + even tighter timings resulted in this:

Highest score for 2697 V2 on HWBOT: https://hwbot.org/submission/4956281_kptrex_cinebench___r15_xeon_e5_2697_v2_1800_cb
And highest that I'm aware of, and that's still using just 2 sticks of ram

Here is R23:

That 9501 score was previous best and it already involved lots of fine tuning, so nearly 300 points above that is hudge
Sadly didn't have Benchmate for this one so will have to re-run it for HWBOT

And on the sidenote, What I noticed during testing was that lower voltage in 0.035-60 offset range was resulting in better stability and scores than something like 0.200 (highest I tested). Might be helpful to someone I guess

Don't really expect to get much higher than this... Unless I find some new trick (again)

Thanks Lex, looks good. Problem is I have 8 ram sticks. Rather need all 32g for vms ect. Just finished several days of tests, including multimetering my psu, and it is my motherboard.
Looks like I somehow fried my vrms. So guess I'll have to sell my 1680v2, my 2697 does me just fine.

Whats a fair asking price for a working 1680v2 in Can? Guys? I need funds for a new mobo.....

 

[grammar_phreak]

johnspack,
They're going for $90 to 100usd on ebay....
Which beats the $250 I paid for mine a few years ago.

Why did you ignore my post where I linked you an eBay auction for one of the best X79 motherboards? You could have bid and won.

My advice is to keep the CPU and instead wait for the good motherboard to turn up on eBay auction. You CPU is still powerful. You can always overclock it and it will rival the latest-gen CPUs such as Ryzen 7 1700X and Core i7-8700K.

This seller ships to Canada. Try negotiating with this seller to sell you only the motherboard and discount the price of the CPU and RAM.

Problem solved. Just took money.....

 

[KptRex]

Got bit of a problem, noticed it while running Aida64 benchmarks to test memory overclock and they were coming out completly different from each other. It took me A LOT of time to figure it out but PCI speed only goes to 2.0 when I have BCLK tuned. (BCLK 100 on the left and 114 sth on the right)

And some games run just fine on that 2.0 speed. M&B Bannerlord shows little to no difference, Dirt 2.0 is fine on some maps on others it's 110fps vs 85... not so fine at all. And Cyberpunk becomes nearly unplayable not only dropping from 53-54 to 41-43 but whole experience becoming much more stuttery

So is there any fix to that, anything. Bios modding,custom drivers,registry editing,custom windows installation,specific bios versions. I lost few days trying to get it PCI 3.0 working by now and starting to get a bit desperate, I think @Zyll Goliat spoked something about it here but can't find it now

Yes I did spoke about that before and it's totally normal on X79 that on higher BCLK OC PCIe that will work on on PCIe 2 but I also did detailed testing and the difference in games and benchmarks was non-existent(actually it was better on Gen2 because of faster CPU clock) that's my case with GPU's like:RX 480,GTX 970 and my current R9 Fury.....not sure but maybe you have some other issues or your OC is not stable on that clock and that's the reason you getting lower FPS because your current R9 290x if working on PCIe gen 2 on 16x simply is not fast enough to "choke"on Gen 2 speeds IF everything else is working properly......tho' I can only assume that more powerful GPU's(probably somewhere in range of 1080TI and beyond)could potentially benefit from GEN 3 on X79

 

[KptRex]

R9 Fury

Yeah I remember my 980Ti was actually running better too with overclock. But tested it over 40 times now and anything above 102 BCLK seems to result in Read an Write at around 7000 in place of 12 000 on 290X. Will try some more things but I'm pretty tired by this now

And I was worried about PCI 3.0 being maxed out with RTX 3080 already, not even wanna think what would happend on 2.0. Like if there is no solution it would mean I have to let X79 go sadly...

No there is no other way around when you OC via BCLK you also OC your PCIe and X79 on that high BCLK simply need do downclock on PCIe Gen2 speeds I could actually make it to work on Gen3 up to the 105 on BCLK on my motherboard but I will rather keep my current 115,1 and GEN 2 on PCIe.....I really could not care less and probably only thing that could be noticeable is if you using NVME SSD in some of yours PCIe slots then yeah sure you can benefit with GEN3 if that kind of thing is important to you.....
Also don't forget that older X58 platform was only working on PCIe GEN2 and never choke any of GPU's in that so called "mid" range actually you can find on this forum people that use X58 in combo with GTX 1080 TI or even more modern cards and some of their benchmarks are exceptionally good......

Well, guess I get to have another run at my 1680 v2 for ocing. My 2697 might been taken out with the vrm death... Time for 16 phases instead of 8:

Dam that price though....

True, but at least you'll have a top tier board!

Did the buyer return your 2697V2 because it was dead?

You should have checked new eBay offerings before you bit the bullet. Here are some new cheaper listings. P9X79 Pro is not that much different from Deluxe. Sabertooth X79 is practically the same as P9X79.

I own the 2697, and it probably died when my vrms bought it. And I already have the deluxe:

And I have more cpus!:

 

[wanna_buy]

I got another kit of CAS9 Dominator DDR3 2400 4x4GB. With VCCSA - 1.05V and VTT - 1.10V, Prime95 custom 448-4096 with 14GB allocation failed in about 4 hours. I upped VCSSA to 1.10V. Prime95 failed after 13:30 hours. I again upped both VCCSA and VTT to 1.15V. Prime95 failed after 3:30 hours. I got frustrated and abandoned further testing.

What do you make of this? Either both kits are faulty or my CPU can't handle DDR3 2400 speed with 4 DIMMs populated? Remember, Prime95 did not fail when my previous CAS9 Dominator kit was run at DDR3 2133 and CAS11 Vengeance 2x8GB DDR3 2400 operated with 1.05 VCCSA.

[johnspack]

Think I need some help with this thing. My 1680 v2 is still stuck at 4.4Ghz, can't go past. I'm already at 1.38v, and 1.1v for vcc and vtt. Might just be the darn chip, and a lot more voltage
won't help. I really don't want to hit 1.4 or higher. Is higher than 1.1 for vcc and vtt safe? 16 phases and I'm stuck at 4.4....

 

[lexluthermiester]

My 1680 v2 is still stuck at 4.4Ghz, can't go past.

That might be a case of silicon lottery. Unless you've done better on another board, 4.4ghz might be the clock ceiling for that CPU at any voltage. It happens. Still 4.4ghz is a respectable OC for that chip. If it were me, I'd be happy with that, set the voltages back down to the lowest stable level and call it good.

I have a rampage IV Black with one dead memory channel. Don't believe its the CPU itself since I've swapped my 3960X with a 3930K as a test with the same results. Oddly the system is rock solid with the 3 working memory channels (48GB Corsair Dominator Platinum) at 2133MHz XMP. I have the CPU clocked at 4.2 (have tested successfully at 4.4 in Aida 64 as well) but the RAM does the same thing at the base of 3.9. The CPU socket looks okay so I am guessing the DIMM channel itself failed. Just living with the three channels for now but would love to get that 4th channel (C) working.

To add to this, the BIOS shows the C channel as "Abnormal" but the DIMM POST page shows them as detected. Windows 10 doesn't see them but HWINFO does. very strange.

Yep, silicon lottery... will not go past 4.4 no matter what. Wonder if I should try my 2697.... it was in the board that died on me. What are the chances a damaged
cpu will take out a motherboard? Should be pretty low right?

Yeah it's low chance....also ain't that easy to broke CPU if the mobo get broken really depend what actually happened to your mobo and if possible electrical short circuit happens for how long?And did other components was exposed to that or yours PSU have protection and automatically switched power off?
