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

[lexluthermiester]

Just a little update.....I finaly get NVME drive for my X79 platform I knew that it's going to work as bootable dsk as I have modded bios on it but I was hope that I will be able to get same/high BCLK OC like I always have before.....unfortunately that is not possible the best-stable BCLK OC I managed to get with NVME in PCIe slot is 105 on BUS and before I was fully stable on 115 that in reality get me around 10% better performance without NVME drive on my Xeon/2697 V2/.....So I believe that I am going to pull out NVME drive and keep it safe with SATA 3 speed but much higher CPU speed.....

Interesting results. Not surprising though. System bus speeds have always been touchy.

Yeah....it's just weird because I have many different GPU's so far AMD and Nvidia and all of them worked with no issue on my high BCLK OC but NVME drive just can't handle it anything above 105 its not stable, in range from 105-108 it will wake up disk and enter the windows but it will cause stability issues above 108 it's not going to be recognized disk at all.....

Ever thought about removing your second GPU and give it a try with your NVME ... could be you reach max PCIe-Lanes and that is causing your BCLK issues. IIRC there are 40 lanes available. Running two GPU´s and the NVME should already use 36! Which is quite alot ... not much room left though.

No difference I already tried that.....and actually that second GPU works on 8 lanes as I put it in the last slot on the motherboard.....it's basically 2D Card low powered GPU that provides really quality picture and thats all it's not a gaming 3D card....

 

[WillingMost7]

Yes, it arrived few days after post ...
I'm using Zalman STC9 paste after years of MX4 since I noticed that MX4 disappeared after cca 1 year of use on two chips..
Max temp under 70C with almost summer conditions, Arctic 120mm tower, 4 pipes, 160W max CPU reported, but case is well ventilated.
4.2 GHz, stock volts, 50% drop (cca 1.23V all-core load).
It needs 1.3V for 4.4 stable, but 200MHz is not worth it for almost 0.1V increase ...
Apparently loves 1.7V PLL, needs 1.1V on NB to be 100% stable at 1866 MHz RAM.
No OC/Volt difference using 1.25 strap ...

VERY impressive for 3930K. I got mine on 4.2 GHz with 1.275V, keeping to wonder if I am missing something.

You might get 4.4ghz out of it if you push the voltage to 1.3v or even 1.315v. Would suggest not going much higher than that as a daily driver. Make sure you have excellent cooling. That much voltage will pump out the heat from that CPU.

BTW, welcome to TPU!

 

[bobbybluz]

I had a 3930K that I got slightly over 5GHz out of. I've posted the CPU-Z of it on here before. That benchmark was done in December of 2012. It took 5 years before core degradation took its toll and I replaced it with a 4960X then the E5 1680 V2 that's still in that PC. The 3930K had a Corsair H100i (until the thicker H105 came out) externally mounted on top of a Corsair 500R case. The 4 SilverStone FM-121 fans in push/pull are also still in use but they have an Arctic Liquid Freezer II 240 between them for the 1680 V2. 11 years out of the fans and Asus X79 Sabertooth so far. The original 64GB of G.Skill Ripjaws DDR3 1866 was replaced by 64GB of Corsair Dominator DDR3 2100 when the 4960X went in (I got them in the same package deal).

The 1680 V2 at 4.5GHz scored over 4,000 points higher on PassMark than the 3930K at 5GHz. The 4960X at 4.5GHz was about the same as the 3930K at 5GHz.

I recently rebuild my x79 System with a modded BIOS running just one single Crucial P3 NVME. I got a cheap PCIe x4 IcyBox (working absolutely fantastic btw.) for it and just put it in the related x4 slot. I have a Rampage IV Gene with a 2697v2 together with 32gb RAM. I can overclock to 114,1 BCLK ... everything above is crashing instantly. My 24/7 setting is 113,4 BCLK with + 0,05 v offset. I´ve no issues with the NVME though. Only thing I recognized is a strange GPU behavior with high BCLK. I sometimes get GPU driver timeouts ...

link to that icybox? thank you

[Zyll Goliat]

I'll send a bug report for this and it would be smart if others do so.
We need to put a small pressure on AMD driver team

@ZOX Just a little update I tried today the latest 23.8.1 drivers with the REBAR ON/1gb/ on my X79 Sabertooth/6700XT and look like they working great so far no issue at all like on some of the previous newer drivers before this driver 22.11.2 as you suggested was also working great.....

you guys got me wanting to try again on that x79 w 2697v2

That brings me back... we all had 5ghz 3930s.back then. I had three of them along with quads 290 Lightnings and 580s. Back then playing the rat race that is 3dmark HoF.

Yesterday I dug out the last leftover 5ghz 3930 I had leftover to build a rig for a nephew, first gaming rig doh. I paired it with a 980ti leftovers, that big noctua cooler now has a role again. I had to google how to overclock 3930s cuz I kind of forgot lol. Fun stuff.

 

[r3down]

yea I only can bclk but i think the gpu is limiting that. and possibly an nvme drive could also

 

[ZOX]

Glad to hear about 23.8.1 working.
I've switched to 23.9.1 and they are also working great. Seems AMD fixed whatever it was...
Installed 6700XT and at 2750 MHz with 1680@4.2, Tomb Raider reports 98% gpu limited at 1440p.
Wanted to go for 6800XT, but seller wasn't opened to negotiations until after 6700XT arrived
About nvme and bclk OC... Adata sx8200 pro is working fine under 110 MHz. Is it a drive limitation or low quality nvme adaper - who knows, but high bclk is possible with nvme.
Anyway, I'll have more time to tinker since my 6 working months have ended and it's time to solve Above 4G mystery...

7900XTX Liquid Devil *READ DESCRIPTION | eBay

<p dir="ltr" style="margin-top:0; margin-bottom:0;">This card was in a loop that had a mixture of metals (aluminum and copper) and was not properly maintained (wife was using it while I was on deployment so I could not clean the loop) hence the water block corrosion. It will need a new water...

www.ebay.com

Got a great deal on this! I will probably clean it up as well as use some Liquid Metal to replace the stock paste and see how far I can push it!

 

[Aquinus]

I finally took the plunge since I almost never use my tower anymore (sadly,) and pushed a modded BIOS to my P9X79 Deluxe and now I have PCIe bifurcation, NVMe boot support, and a bunch of settings that I'm almost afraid to touch. I just bought myself a 2TB Samsung 980 Pro NVMe to replace the 512GB 960 Pro I got half a decade ago. I was using that just for game storage and I'm going to reinstall Ubuntu on the bigger drive and get it set up with some NVMe root FS goodness. I've already tested it out on the 512GB, so now I just need to swap hardware out. It appears that Ubuntu 23.10 really doesn't like it when I have RSTe enabled, so I needed a fast disk I could boot from since my SATA SSD RAID-0 was now out of the question for booting.

I almost forgot how far ahead of its time the P9X79 Deluxe was when it came out. To think a board from ~12 years ago could boot from a NVMe at PCIe 3.0 is pretty crazy to be honest. I'm also glad that it didn't brick my motherboard, however now my P9X79 Deluxe has the ROG logo on boot which is funny.

It looks like I may finally be retiring my Asus X79 Sabertooth/ E5-1680 V2 rig. I'm thinking of using the Corsair Carbide 500R case for my still uncompleted Asus X99 Rampage V Edition 10/ 6950X build and moving ahead one generation. It's been a great 11 year run for X79 but now I want more USB 3.0 front panel ports, native NVMe, WiFi, more CPU cores and more RAM. I have 128GB of G.Skill Trident Z 3333 on hand and a like new EVGA GTX 1080 Ti FTW on hand for the upgrade.

Traitor!!!! lol joking but will look forward to your posting about new system and keep posting about old system!

I have to admit, after using my 3930k with a Vega 64 for a week or so again, I'm reminded of how capable this pair is. I decided to buy SnowRunner and see how it runs through Proton and I have everything at ultra at 4k without AA and it runs a steady 60fps. I honestly can't complain about that. I may be biased though because it can easily keep my office warm in the winter and it's getting chilly out.

 

[lexluthermiester]

4k without AA

And that's likely why. At 4k, AA just isn't needed.

 

[ZOX]

Good news everyone

Seems xCuri0 fixed Above 4G bug for x79. Currently running 16G rebar size ...

 

[wanna_buy]

Hello everyone. Long time no see. Recently I got 64GB G.Skill RAM for my E5-2699V3 & Rampage V Extreme setup. I managed to lower the timings to 5-9-7-10-1T which was benchmark stable in Cinebench R15. Has anyone ever managed to get DDR4 to such low DDR2-level timings?

My main X99 board went bad because it was occasionally refusing to show video signal upon boot with memory debug LEDs blinking. I reassembled my main rig on P9X79 Deluxe and Xeon E5-1680V2. The above record was achieved on my secondary PC used for benchmarking.

I'd be impressed if that were DDR3 timings, but DDR4? That's nuts.

On an unrelated note. Who ever said software RAID-5 was slow? This was with my very old 1TB WD Blacks (4 of them.)

Also, I finally was able to apply an undervolt to my Vega 64 in Linux and I'm seeing a nice healthy 8.6% improvement just from the lower volts, a little more fan speed, and a very slight underclock to 1600mhz on p7 to keep the card happy at 1000mv. I'm still in astonishment that there is that much headroom with these chips. I'm also pushing a healthy 4.6Ghz on all cores on my 3930k. Long live SBe!

 

[MaksDampf]

Still some people with 2667v2 experience around?

I can't get it to turbo higher than 36x, but it is supposed to have a 40x Multiplier on 1T loads. I can get it to 39x when i limit to two cores in the BIOS, but whenever all cores are active i can't get higher clocks than 3600mhz even if the workload is purely signlethreaded. I trief hwinfo and it never leaves the 36x multimplier. I tried all the settings, c-states, no EIST, with EIST, additional turbo voltage, voltage offset minus/plus, undervolting, overvolting, etc.

Is it my cheap board with shitty VRM limiting me? The CPU runs a lot cooler than the 1650v1 and it never draws more than 95Watts too, while the former could easily best 165W at 4.2Ghz, so the board must have had some reserves. It feels like all the power settings for turbo power, current limit, etc. don't apply to 2600v2 xeons.
If i set the Multiplier manually to 40, my BIOS displays a 4Ghz clockspeed, but it never does that in windows. Is this a known windows10 problem, maybe because of the meltdown patches?
My board is an Asrock Xtreme3 with BIOS Version 2.90A with NVME support. It only has 5+1 Phases, but i added a beefier heatsink which improved VRMtemps by 10Degrees under load (its now 89C with 170W).

Is there some sort of turbo boost unlock with V2 Xeons too or was that limited to x99? I'd really like to achieve the 40x Multiplier.
