You don't have enough rad.

The setups I've been using w/the 2600k, a 990x and a 980x (oc'd to hell and back) include an XSPC 360, HAFx case, Monsoon resi's, Swifttech DC pump and 3/4in hosing.

The XSPC has 6x Coolermaster R4 fans @2000rpm

The highest temp I've seen at 100/100 is 55c...

On average I see high 30's only low 40's if gaming and benching, as I just said, 50-55.

With 2 590's that changes a lot because wattage dissapated just nearly doubled AND you've added 2 new pressure locations to your loop...

If you're going to push that card to 1V, your delta is going to change almost dramatically because you're pushing the same rad.

My suggestion to you, at those temps, you may be okay, it might peak into 65c/75c (even those are acceptable) but, I would perhaps get a beefier rad and look into dissipation.

Skinnee's lab has all the new tests on the latest batch of RADs, I'd check those out and definitely invest in 1.
Argh I have the beefiest rads my case can handle without going external mount. RX120 at the back (which actually is external since it won't fit inside), RX240 on the bottom, RS240 on the top, all equipped with GELID Wing 12 PL running at 1900RPM. They're rated 1750, so maybe I should add a little resistance (slow them) to achieve better static pressure? I have three 2000rpm Sickleflows (R4) on my shelf but they don't push or pull nearly as hard as these GELIDs do. At 100/100 my CPU hits 58 (mobo overvolts to 3.771 @4.4ghz no matter what I do) and my GFX hits 46 core 2 and 53 core 1.

I don't know what to make of the delta between the cores as it was there on air as well. WCing the card has taken it down from 11C max load to 7-8C max load. I think there's still an air pocket as well. When it gets to 43+ on both cores my frustrating vortex reappears between the gfx card and RX240. Thought I had bled that out, but apparently not. I should also probably change pump speed because right now the 35x is going full-tilt in a loop w/o much restriction which I've heard actually hurts temps.

ETA: I DO NOT have two 590's. Just one. When I talk about cores 1 and 2 that's Core 1 Card 1 and Core 2 Card 1.

It sounds like the systems you reference had a single RX360. I have the equivalent of that plus an extra RS240 and the 2600K has a lower TDW than any Intel Extreme CPU so theoretically I should be fine? Sorry if I misled you. I don't want anyone to look at my scores and think, "wow, that's two 590's? ... Really!?" It wouldn't help the case of the 590 at all.

I would NEVER run 1V 24/7. I generally OC for benches then back down to stock voltage or .925 for games since when I played BFBC2 at 740mhz I only saw a ~4fps increase, which is useless when everything already runs faster than my monitor.

Last night I did go to the big 1V for a couple hours to bench. PDL kicked in super hard for 3DMark so I went to Heaven. I could only get Heaven to run at 785/1570/864 @ 1.000V. I will never catch-up to Wogga at this rate Temps never went above 44. I'll admit that I was hoping for more since the card went to 740 at .975 with ease. At .975 the max is about 743 but I don't like ugly numbers. It seems like I have enough rad but I do want lower temps considering this loop ran ~$570 before fans which were $19 each

my card is broken, it works w/o one capacitor (teared it out) and yet had no problems running @1.05v for hours...there should be no fear.
now i'll try to find courage to flash MARS II BIOS onto my poor 590

Make sure you know how to do a blind flash, a force flash, do it outside of windows and have a backup card just in case you need to reflash old bios using the other card for display. Don't do it the easy method in windows.

Prepping a crazy flash like this:
Uninstall all drivers/disable SLI / Surround.
Delete all nvidia files in safe mode.
Attempt from DOS, have backup BIOSes in the same drive named extremely simple: ex. backa.rom / backb.rom.
Pray.

Regarding water cooling temps, I was not satisfied with max temp so added a 3rd 120.3 radiator. This should not affect idle temps around 30~34c, but should lower max temp by about 10~15c, so hopefully max temp will now be 45c.

umm...those MARS II BIOSes are .bin, not .rom...i need some time to read about all this stuff and find the way to convert it to .rom

What kind of outcome is expected with this Mars II bios flashing as far as possible damage to the card?

And wouldn't this still be useless due to PDL? Won't nvidia drivers still recognize it as a 590 and put it under the same garbage limitations?

no more PDL i think =)

Smo, i already have NiBiTor but it wont recognize mars 2 bios -_-
post #2048 of 5154
Well let us know how it goes Wogga, I'm curious to if this is potentially the thing that redeems the 590.

PS: I flashed mine from Cains modified back to stock bios using bin files Wogga. It was using the windows nvflash method tho, not sure if that matters.

tried just putting those bins over nvflash.exe and all i`ve got were several beeps and nvflash window, closed in a second.

anyways, i've already posted somewhere here (or maybe in flashing and OC thread) about one guy that flashed bios from 580 and his card didnt blowed up or smthing like this.. it was unstable but still worked. so i think it wont be painfull to flash mars bios. as you can see, the highest voltage in mars bios is 1.1v:

Performance Level 3
Core Clk: 782.00 MHz
Mem Clk: 1002.00 MHz
Shader Clk: 1564.00 MHz
Voltage: by ASIC (1.0375 V - 1.1000 V)

dont think it will burn my card.

Wogga your Bios are probably write protected, just run the nvflash.exe by itself and itll tell u the command to disable the write protection.
