The RTX 2080Ti Thread

Dont do it. If the card is OC'd and pushed above its 300w limit (Pcie slot = 75w, 6-pin = 75w, 8-pin = 150w), it could do damage, possibly to mobo pci-e slot. Most 2080ti's come with 2 x8-pin, so a bit odd yours has a 6-pin. Some 2080tis come with 3x 8-pins (MSI Lightning), so are able to work with much higher power limits. Point is, not all 2080ti's will be equal in power draw handling, so with 6+8 pin take care with bios power mods.

 

Hi fantaskarsef

No to the date, didn't run to issues, I think rating of PCI_E power cable is 150W(peak 300W),as 6 pin and 8 pin is total 150W for 8 pin and 6 pin is 75W and extra PCI_E slot additional 75W

Using on my RTX 2080Ti Galax 380W BIOS and no issues to report

Many people run or crossflashing their GPUs for few years and no issues, although I have seen few guys bricked their older GTX1080Ti with HoF BIOS

Regarding the frying motherboard this shouldn't happen, you have extra power connector for PCI_E(molex), this I recommend to use if you are using multiple GPUs like I do

Hope this helps

^ Cant say it applies to all cards or mobos, but their have been instances when GPUs outfitted with insufficient power connectors (ie, RX480) were overloading the mobo pci-e slot and some have reported fried pci-e slots as a result.

The cause was AMD allowing (by design) higher than the max recommended current over the PCI-E bus than the pins are specced for.

 

Thanks for the replies @jura11 @alanm and @Mufflore .

To be honest, I anyways think I'd be most limited by thermals, although that helps with my build (custom loop). I'm fairly sure, I could not draw 380W of power out of my card anyway, as it starts to throttle at around 40°C anyway.

I too was worried about my mainboard most, since the PSU can't really see if it's a six or 8 pin connected, but the PCIe slot is limited to those 75W, and I'd rather not fry my mainboard (although I have one in spare, it's a PITA to rebuild the loop, and I'd much rather put that work into a new rig with Ryzen3000 incoming).

Yes, my EVGA 2080TI XC only has 6+8 pin, but as I said, I'd not worry about those 300W via power cables too much, as I expect to run into the temp target and throtteling much faster than the power target limiting me.
Hence I wanted to ask if somebody tried the power punch BIOSs on a 6+8 card already. It could potentially be wise to "just" go for a 320W BIOS (if one such exists, I did not check yet)

 

Hmm might be true, I didn't bother to check yet, as I haven't even hooked up my card yet (waiting on waterblock).
On Techpowerup, there's a BIOS for my card which says 260 target, 338 limit, is this the one you were referring to? If so, I think 335W should be sufficient for my use (and temp space I can drive my card in).

 

Yes the XC one you linked was the one I was looking at. Looked pretty reasonable, might still flash a newer version (there's a couple of refreshes for the XC), probably next weekend.

 

I tried maxing out the card at 99% load using Superposition and running it several times in a row (I don't have the paid version which has a loop feature). Anyway, I noticed that while OCing the card never stays stable at a specific clock, it always fluctuates both up and down even if the temps and load are stable. MSIAB reported that I'm constantly hitting the Power Limit so my guess is that having a 130% power target would make the clocks more stable like my old 1080Ti.

 

What's your card's power limit? Stock BIOS or cross flashed?

 

It will help (and you should do it regardless) but you may find the clocks still waver somewhat.
Max power limit is quite restrictive no doubt to extend the running life for high temp users.

 

It's 110% and I haven't flashed anything. I'm also using the latest BIOS for my card (confirmed by MSI).

It's a dilemma since one would wish to handle a card with "unrestricted" access but I also understand that giving such power in the average users hands isn't a great idea from a business standpoint.

 

amazing temps.. What is your water cooling system like? Do you have the CPU and GPU on the same loop?

 

Hi fantaskarsef

I'm currently using Galax 380W BIOS and max power draw what I have seen has been 310W, usually in gaming I see 290-300W,didn't hit power target limit once, with stock Zotac BIOS this has been very common and I hit power target limit with any benchmark

Regarding the motherboard PCI_E slot power draw, unless you are do wrong or bad job on shunt mod on yours RTX 2080Ti then you shouldn't be worried about this, I modded only once GTX1080Ti with shunt mod, when XOC hasn't been released and no issues, friend is still running his shunt modded GTX1080Ti with same X99 Rampage V Extreme and 5930k

This is worth to read, its from Kingpin

As I said running on my RTX 2080Ti Galax 380W BIOS and no issues there, friend running on his Palit RTX 2080Ti and EVGA RTX 2080Ti XC is running too same BIOS, I build these loops and usually I test them and trying all GPUs on my loop prior to installing GPUs to their loops

I just wouldn't run XOC BIOS on air cooled GPUs but that's my view

Hope this helps

Thanks, Jura

 

Hi there

I would have tried Galax 380W BIOS but not sure how yours GPU cooler would handle 380W, I usually running these BIOS on water cooled GPUs and I know is very easy to cool such increase

Running now this Galax 380W BIOS and didn't encounter any problems or didn't hit any power target limit what I do, in gaming I usually see 290-300W and in Superposition 310W, only in FurMark I seen full 380W power draw

Over on OCN guys running Galax BIOS on their air cooled GPUs and no issues

XOC BIOS has been very popular on GTX1080Ti and there I have tried this BIOS and no issues, guys running previous generation of XOC BIOS on their GTX1080Ti without the issue or problems

I wouldn't run XOC BIOS on air cooled GPUs but that's my view

Hope this helps

Thanks, Jura

 

I would suspect he is running chiller there, bit agree very nice temperatures

Hope this helps

Thanks, Jura

 

Hey guys how do I find out what memory I have on gpu?

edit. I have Samsung on my duke
It boost to around 2100mhz with 140 on core and 350 on mem.

 

Hey Jura,

yes I was mainly worried about any potential high power draw on the mainboard's PCIe slots, not so much the power connectors. I was aware that physically, the 8 pin does not add anything, since when I built my rig it was easy to see that the cables presented as 6 or 8 pin are physically 100% the same cable, those two extra pins connect to... 2 of the 6 pins. So no real difference anyway.

 

Hey.

I suppose I could try the Galax BIOS but it's also dangerous since bricking an expensive card like that would be close to the end of the world My wallet isn't big enough to just go and buy a new card.

I don't think the cooler has any problem here. I do believe however that the fan curve could be slightly more aggressive.

You have your card under water? Cause if you're stable in Super position Extreme at 2100MHz on air, then you got yourself a golden sample. After stress testing mine it hardly does 2000MHz on air even at a high fan profile.

 

No, this is playing games like battlefield v, anthem and assassins creed. It usually hovers around 2080 but has gone to 2100. This is not on water just the normal 3 fans.

 

Well congratulations

Either you have a great card (I'm pretty sure you have) or I have a crap card

 

Hi there

I would try Galax 380W BIOS, just make sure you are save yours original BIOS, bricking GPUs this shouldn't happen, I know few guys bricked their GPUs with different BIOS, usually they flashed 3*8 pin to 2*8 pin or 8 pin and 6 pin GPUs, some guys have flashed on their 3*8 pin XOC BIOS as well and GPU won't pass 1350MHz and GPU stayed at safe mode etc

XOC BIOS I will be testing probably next week or so, but for now Galax 380W BIOS is more than enough for me

My RTX 2080 Ti is not the best OC for sure, with stock BIOS I wouldn't be able to OC or run beyond 2070MHz, running now 2100-2115MHz

Will be have for testing EVGA RTX 2080Ti XC and Palit RTX 2080Ti and will test both and probably will swap my Zotac RTX 2080Ti for EVGA or Palit if they clock better, have different Heatkiller WB coming next week

Tested friend EVGA RTX 2080Ti XC and with this card I could push beyond 2150MHz easy and +1200MHz on VRAM



Hope this helps

Thanks, Jura

 

Hey Jura,

nice that you mentioned that problem with the connectors 3 vs 2, I figured something like this could be an issue, but didn't want to try it out.
Also, did you put your friend's card under water, or did you use a chiller? 2150 sounds like kickass, myself having the same card's giving me ideas...
