that's not MEM that's VCCSA. Also looks like it's just a ripple suppression cap so it doesn't really matter. If you want Sapphire tech support should be able to tell you what it is. They gave me the specs for a cap on my R9 380 that I broke.

bump Price drop on CPU to 770 eur

Bump. RAM is now 110Eur for 4 sticks and 60uer for 2.

In the CZ I had a set of MAUDIO BX2 D5 speakers with a sub. In the UK I only use a Bose SoundLink Mini

Well my Sabertooth is prepped. I might also do my Z87 Mpower but I'm not sure if I'll actually bring my 4790K to the event.

can you try run lower timings on the RAM? Something like 1333 7-8-7-22-1T on 1.8V should be possible and will give you a good point boost.

Ok so I did another round of testing. I didn't do a write up since it was a really basic check. I underclocked the GPU down to 500mhz. I set core voltage to about 1.4V surprise surprise no FPS drop. With these settings the card was pulling only 222W. Stock power draw for comparison is 312W. Mind you I chose a specific view in Heaven which causes AFAIK the highest possible power draw. So the conclusion is that the power management is intervening based on power/current limit because when running 1.4V with a 222W power draw everything was fine but running 1.4V with 420W power draw causes the massive FPS drop. From my testing with modded BIOSs ranging from a 4096 core 350W Fury Tri-X BIOS from Sapphire to my own 65000W BIOS I've also come to the conclusion that the BIOS doesn't have any impact on the amount of throttling occurring. So a physical power mod should work however physical power mods on the IR3567B are risky because the current sensing is per VRM phase and is used to load balance the phases. There is a chance a Physical Vcore mod might also work but I can't check because ATM I don't have what I need to do a hard mod. I've tried BIOS modding however I probably have no idea how Fury X BIOS works. If some one could test with their own Fury X for the same effect that would be great.

I already checked core clock with GPU-z and it's 100% stable. I can't check VRM temps because nothing picks them up.

AMD GPUs don't work at all like Nvidia. Nvidia cards automatically clock up but AMD cards are supposed to run at what ever clock you set them at unless they are overheating or hitting the power limit.

MOAR DATA: I dropped core clock so I could test at negative voltages. The power draw number is current on the 8 pin PCI-e connectors. So behaviour wise this looks pretty much identical to the results at 1050 core clock. The power draw readings also don't reveal any useful trends other than the fact that power draw scaling is mostly linear. Now this goes against all the data I have from measuring power draw on CPUs. However the drop in FPS means that the GPU is doing less work so I'm still going to stick with my theory of Power Tune messing with something which results in the linear power draw scaling and drop in FPS. I do have an idea for how to prove that power draw is exponential with voltage. I'll just run the card at 500mhz core clock and test it with core voltages ranging from .95V to 1.175V since there power tune doesn't seem to be intervening. Also I tested if 35A is the OPP. It isn't I ran +252mv with 1050 core and the card ran fine for several seconds which if OPP was at 35A would have been a trip.

P = I * V I = V/R P = V * V / R That's the theoretical proof for power draw being exponential with voltage. I also have a ton of real world test data supporting that theory. I'll do more testing but so far I think Power Tune is completely broken and it's doing some kind of micro throttling. Also I think I've managed to trip OPP at 35A on the PCI-e 8 pin. I'm gonna hack Trixx for even more Vcore and see if I can get it to happen by just raising core voltage really high. Just to make sure that crash was indeed OPP and not an unstable core clock. (I'm so gonna end up breaking my Fury X)

Looks exponential to me: The only thing that goes up exponentially with voltage is power draw which is why I think it's a power management problem.

Anyone with a Fury X willing to test if this is also the case for them?

5960X - 720 EUR shipped to EU or UK. RESERVED It does 4.7Ghz Cinebench stable at 1.35V and was stable at 4.6Ghz 1.325V for daily usage on RVE. The IMC maxed out with my Crucial 2400mhz CL16 kit at 2666mhz CL11. Not that great considering that the kit does 2800 CL9 on my new one. Cache did 4.5Ghz but I think I was running it at 1.45 or 1.5V for that. 4x4GB GeiL Super Luce 3400 16-18-18-34-2T NO LONGER AVAILABLE 4 sticks for 100 EUR shipped to EU or UK 2 sticks for 60 EUR shipped to EU or UK I suspect the ICs to be Samsung D-die. The kit hates the RVE and I never got it to do rated spec. I did manage 1500 12-15-15-28-2T at around 1.65V. They should do rated spec on X99-SOC-Champ but I don't have the board so I can't check that.

Core never went over 46C during testing. I think when I started testing I was at 43C. Mind you after each set of results I went and tested that stock clocks still gave 274FPS. The difference in performance is instantaneous. As soon as GPU-z picked up on the raised Vcore the FPS was down. I tested with Trixx intially but Afterburner also does the same. If I can fix this I see an easy 19-20K graphics score in 3Dmark Firestrike. Because stock clocks does 17.8K and the cards seem capable of core clocks between 1200 and 1250mz with enough voltage.

So I kept getting negative scaling with my Fury Xs in benchmarks and so I decided to do some formal investigating. This is what I got: The numbers are from Unigine and as you can clearly see raising core voltage in Trixx is causing performance to fall of a cliff. Power limit doesn't have any impact on this. I tried to fix this by using the 350W Sapphire Fury Tri-X OC BIOS. That didn't do anything so I modded the BIOS for 768W. That still didn't help. The performance hit from voltage is so bad that 1175mhz core clock at +100mv gives the same FPS as 1125mhz core clock. I still need to check if this happens with hard mods for voltage. If it does I'll probably try a hard power mod too.

So I went and flashed my Fury X with a 4096 core Fury BIOS. I still submit it as a Fury X right? Because it looks like a Fury in GPU-z.

I thin there is a bunch of connectors hidden under the sound card. Though that might be the previous impact.

I guess I'll just use the dead R7 260X I have. If that doesn't work out I can just hack up the A88X-D3H I killed or the 990FX-PRO that randomly died on me.

what would be a cheap card to try practice this on?

Yeah it's 26 quid with a return ticket but I get to bring in hardware depending on what I want to bench.
