Lol good one.


Temps aside, I think I finally managed to get around to how the curve works.

Whats funny is with 2050 at 1.093v, I get absolutely no perfcaps. The box is just blank. But the chip unfortunately can't do 2050 for long and it just crashes after a while with andromeda.

Now drop to the next bin which is 2037 at 1.075v, it holds and is perfectly stable, but I get a rainbow of perfcaps lmao.

Damn Nvidia logic.

To me they look like they're the same reading, expressed differently. i.e. same numerator, different denominator. The nomalized value appears to correlate with the % dialed in via afterburner.

I believe they are right.

Please look at my Timespy doing 1.050v and 1.075v.

Below, I do not hit any perf cap at all. Even though my power limit is set to 120%, I'm only using 101% maximum power draw.


Here I hit the perf cap of power limiting a tiny tiny bit in time spy. My maximum power draw was only 103% in AF, but it seems the normalized TDP was hit here.


Although I never hit it in gaming or with superposition. Here is 2152 Mhz @ 1.093v



I believe the problem is being overblown though. With the shunt mod, I'm drawing roughly 100 more watts, around 400 watts total. I haven't ran a game that has drawn even close to this much power. I think For Honor (which is just as bad as Ghost Recon when it comes to optimization) drew up to 92% just at one point, but never in the 100s.



I believe this power limit "issue", if you want to call it that, is being overblown. Even if we figured out a way to get past it, it's not like the difference between shunt and non shunt mod in performance. Look at my pre-shunt mod perf cap here.



At best we'd probably gain less than a fraction of a 1% of performance in only Timespy and Firestrike? But no performance gain in any gameplay.

EDIT: I did not shunt mod the resistor by the motherboard, but that could probably give you the extra TDP you need or not. I don't know how it relates to normalized TDP. But why bother drawing more power from your mobo? It will risk damaging it. AMD updated the RX 480 for a reason, it is not safe to draw more than the recommended power from a mobo from my understanding. Correct me if I'm wrong.

Sell the old i-7 for $250~+ and have you a whole new platform's performance for less than $100.

Edit, price went up $20. word has been getting out on these and they have sold a bunch lately.

Good luck EVER finding one used. Nobody is going to part with The Gaming Behemoth lol.

Thanks a bunch. I will probably have to flash the bios of my msi g55 sli mobo. Hopefully it supports it. I will probably have to Google it a bit and be sure i can use it. I live in Norway so the shopping is 40dollars and then 25% VAT on top og that. Need to know it works first before i invest that tongue.gif

crazy, iddnit? them perfcaps, if they arent pink... screw em lol. just run HWinfo64 instead of gpu-z. Hell, it's better anyway. You can add anything to the rivatuners OSD and monitor everything on screen in game. Screw dem perfcaps.

aye, you have to have a z97 mobo. have to figure cost of that minus selling price of your old mobo to see true cost i guess. It's a no brainer upgrade if you have the z97 already. If you can find a deal on a mobo. I grabbed my son a z97 gigabyte mobo reconditioned of newegg for $79 bucks, tho. and ebay'd his old asus amd board for his 6300 and fetched $75 for it, so it can be done at little to no cost. If in Norway that's possible, that is.

Also to consider is what ram you have on hand or would need. ddr4 is freaking outrageous high right now, and even ddr3 prices have gone up, but you can still get g-skill 2400Mhzc-10 8x2 16gb kits for $100. And that's top of the line ram for a z97. If you are going to do a full upgrade you are going to be cussing those ram prices/ but if you some some to sell, life is good. I just sold a 2400Mhz corsair dominator plat 4x4 16gb kit on ebay for $220 and replaced it with that gskill kit and made $120 with no perf change at all. just went from silver to red heatspeaders for $120 bucks lol.

Yeah, exactly.

Well I get vrel, since the curve is set to make 1.075v the highest value the card cannot go any higher due to user set limitation and hence reports vrel.

vop I have honestly no idea what it is.

pwr is something that shouldn't be happening since it had no issue at a higher clock and voltage.

thrm also shouldn't be happening since the temps are now lower with this bin compared to the higher bin and yet was not reported at the higher bin.

Mind = blown.

I searched for the specs of my mobo. It is a Z97 and it says it supportsider 5th gen cpu. But will i be able to clock it beyond 4ghz on air? I use a noctua D15S today.

yeah, on that you will. they run cooler and hold more volts ,both, than 4790k.

They are really amazing lil suckers. i can run 4.3 at 1.38v core and it stays under 70c on my 120mm double-thick 'fatboy' lil ole aio, in BF1 which pushes cpu usage through the roof. If I run it at 4.2 (i do) at 1.28v, it stays in the 50c s in that game. 40cs in any other games. And your cooler's perf is probably on par with my asetek fatboy $100 cooler.

Damn, bro, you are good to go. make sure you join us here. WEALTH of info in there. http://www.overclock.net/t/1583537/intel-broadwell-c-ownership-club/870#post_26053281

100% approval rating in that forum and 90% of us came from 4790k's not sure if we'd even get a bump, and boy do you ever. GREAT gaming chip.

Just installed my 4x 1080 Ti GPUs on my 2nd rig and put the EVGA 1600W T2 PSU in there as well. Ran 3DMark Fire Strike Ultra - runs fine - all GPUs scale (score is much lower since I'm using the 3970X @ 4.50Ghz).

However, Heaven 4.0 doesn't scale well even at 4K w/ 8x AA!

Games also are not scaling anywhere as nearly well as the first rig w/ the 6950X @ 4.30Ghz.

Can the CPU alone cause this? I'm also running "only" DDR3 @ 2133Mhz (32GB) on the rig with the 4x 1080 Tis whereas on the other rig, I have DDR4 @ 3200Mhz (64GB).

Further, if I use DSR to play at 5K (this rig has the RoG Swift @ 1440P @ 144Hz), the scaling is pretty bad where as 5K on the other rig scales >90% across all 4 GPUs.

If I bump up resolution scale to 8K (150% from 5K or 200% from 4K UHD), the game (BF1) crashes instantly with a DirectX error.

The other rig can play at 8K all day (4x Titan XP).

Why is the scaling so bad when all other components (other than CPU & RAM) are the same? Could the X79 platform itself be limiting scaling somehow?

Would like some advice on this.


Make sure the pcie speed is on gen3.
There is problems on x79 reading the correct speed even if bios is set to gen3.
In my case if I try to do bclock OC my speed change to gen 2. If I run without OC speed keeps on gen3.
Look for "x79 pcie patch" on Nvidia o EVGA forums, run the file as admin and restart. You can do regedit manually as well. Check the speed with GPUZ.

With my E5-2690 and 1080ti SLI :
battlefield 1 @ 4K Ultra, just starting the campaign.
Gen2- 75-80 FPS
Gen3- 105-110 FPS

Also, not sure how many pcie lanes the 3970 has, this could be another factor but I guess the speed is the problem because many ppl is using 8-8 configurations without problems.👍🙃
