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

For X79 E5 1680 V2's are unlocked 8 core Xeons. I have two of them. Their performance is nearly identical to a X99 5960X when both are overclocked to the same speed (4.5GHz for mine). The 2697 V2's have four more cores but are also locked.
After some quick testing (only some CB runs) my 1660v3 (8core xeon variant of the 5960x) @ 4ghz CPU and cache with 2400 CL 10 is delivering nearly the same numbers like my 4,5 ghz 1680v2 2600 cl11 is doing even at something like cb15 (no avx/2).

Clock for clock (only did some runs since my cooling is not set up) i saw a uplift about 15 - 20 %.

You bought E5-2697V3 in late July. Did you ever get it? Did you undervolt and overclock it? Can you post your CB R15 and R20 scores?
 
Yes received it but have not tested it yet (vor modified the BIOS). Will try it out soon.
Your post on page 82 stated that you own Rampage V Extreme. I have attached my modded BIOS file for Rampage V Extreme. You have to copy to FAT32-formatted 4GB Flash drive. Insert the drive in the lowest black USB 2.0 port. Then you press the ROG Connect button for 3 seconds before it starts blinking. After the flash is completed, the light goes out. If after pressing for 3 seconds, the light blinks several times and turns solid, this means that the motherboard did not recognize the flash drive.

Did anyone read Zen 4 reviews here? I have noticed that stock 6-core Ryzen 5 7600X scored 2481 CB scores in Cinebench R15 which is higher than 2296 CB scores generated by my stock 18-core Xeon E5-2699V3. I mean, three times less cores beat 18-core beast. That's 8 years of progress. :eek: But Xeon is 3 times cheaper than Ryzen 5. :D

Stock Ryzen 5 7600X scores 6040 CB scores in Cinebench R20, which is higher than 5986 CB scores achieved by my 18-core E5-2699V3 with supposedly 24/7 stable overclock for most V3 Xeons (-0.05 undervolt on 103 BCLK).

Im running an Ali Express 1680v2, RIVE and Gskill 2400cl11.

125 strap 126x35=4422mhz @ 1.41v, LLC Ultra High, VTT 1.15v

I'm using 125 strap to get around the memory write bug.

Not quite happy with the high voltage at just 4422mhz. Trying higher frequencies always ends up in whea uncorrectable error bsod.

Haven't really tried 100 strap OC'ing because of the memory write bug.

temps stay below 75c with H110i. I've been using coretemp and when running stock clocks the power reading goes up to 180w+ while when OC'ing im not seeing it go higher than around 160w.

I had my previous 3930k running @4711mhz @1.385v high LLC. slightly higher single core perf.

what are your pll /vccsa voltage values?
 
Its both set at auto. vccsa is doing around 1.155v PLL is at 1.787v

Hi,
On a good bios both should be around default 1.05v

Bad bios could max at 1.25v :eek:
 
i also had a 3930k, used to run at 4.5 @ 1.28v vccsa 1.2 (memory required). Since i wasnt ramping bclk, i actually got better results with LESS pll than more oddly enough.
but i wanted offset mode and EIST so YMMV
 
Well...If I could guess I say theoretically it is possible...I mean on X79 we can turn on Above 4g decoding in bios the thing is that someone we the little knowledge could possibly moderate the bios and solve this problem in the future.......BTW Also some people claim that resizable bar working on older card without the problems even if the GPU are not supported....here bellow pic with the R9 390....

They claim that actually unsupported GPU is not the issue if your motherboard/bios allowing that resizable bar could be turned on....

just isn't possible, these x79 boards don't have a contiguous range to enable Rebar+4G Decoding, the max is 1GB.
 
Sorry all! I am getting over Covid and was on here sparingly checking articles and such but somehow I wasn’t getting notifications of this thread anymore! I just remembered it existed and checked in lol. Anyway great to hear people like pecan still getting 1680’s and posting away in here!
 
My X79 rig is now over 10 years old (everything but the case and mobo have been replaced over the years) and the 1680 V2 still runs like a champ. It's amazing that a decade old PC runs as well as it does. Rock solid stable and has never let me down. The E5 1680 V2 is among the top few CPU's Intel has ever produced. I still have that second spare Asus Sabertooth X79 and another 1680 V2 stashed away but now I'm in the middle of building another X99 setup for my 6950X.
 
Guys, any thoughts on Intel DX79TO motherboard? Overclocking and such, no heatsink on a VRM, almost no data in the web search, apart from the shallow "review" on Tom's...

No go for me.....problematic VRM also possible driver issues and no support for V2 Xeons as I understand....Well If you want to build RIG with the I7 3820,3930k,3960x or certain Xeons(V1) then I guess you should be fine......
 
It won't go over 4.835mhz, period.
I set the memory to 9-10-10-24-2 at 2133mhz. Too bad, was good with voltages and then hit a wall, I'll look for a gold copy somewhere.

Yeah, I'm not surprised, as the price suggested something isn't quite right. It's bundled with an E5-2630.

I haven’t seen one much over 4.7 stable! Even 4.7 stable with water only is the rule, so if you got it to hit 4.835 you already got a golden chip IMO.

No, 4.835 ghz is as good as it can go, it's stable up to 4.750 ghz, I haven't researched much.
I thought it would be able to go over 5ghz for the bench, but unfortunately it can't, and it promised
Better luck next time and I'll see how stable it is at full.
 
It's me again, on a X79 board hunt. Any thoughts on this one:

I know it's one of the best, but still, do I need to be aware of anything?

Nah this is a GREAT mobo.....personally still using it with my 12c Xeon 2697V2 and I never have the single issue also you can get modified bios for it with some good perks(NVME.....etc).....
