New 6700xt not posting...

[djxput]

So been 3 1/2 months trying to get a gpu and finally got one - Gibbos voucher 6700xt.
And I can't get it to work (no post, no bios screen, hdmi nor dp).

- I have a 970gtx that works fine, already retested 3 times with each card.
- I previously had a red devil 5700xt that used a 8pin and 6pin same as this card and the 5700xt worked fine.
- I have a ax850 gold corsair psu.

Tried different pcie cables (didn't help).

Any other ideas.

was going to say the PCIE Cables as my Red Devil 6700XT does not like it if you use the daisy chain cables...

Ironically my Reference RX 6800 is happy as larry using them. In that Rig I think its a Corsair TX650M so nothing too fancy. Not sure what to say if you have tried multiple cable combos

When you say your 6700 didn't like a daisy chain - did it post at all? I'm getting nothing.

Installed mine today, no issues so far.

As others have said, using 2x 8 pin cables (although this card only needs 1x 8pin and 1x 6pin - despite the spec sheet!).

I did initially have an issue posting, but just moved the Display Port cable into a different port on the card and it worked. Switched it back later and all is fine. Could just be a coincidence rather than a fix

Are you running two monitors or screens? Maybe try with just one first.

I'll try a diff dp port see if that helps. But did try the hdmi and dp...

Latest motherboard BIOS.

Ya funny was going to clean install windows again (it's a recent build), but just put a new bios on it dated 3 days ago. A beta but the other card boots up fine.

 

[djxput]

clear cmos? Have you also inspected the card for damage? Checked mb pci settings if doesnt work pcie 4 try 3?

Don't see any damage, I'd have to put my 970 in to go to pcie 3, sort of hate to do that since I got a wdsn850 pcie 4 Nvme drive. Havnt cleared cmos? But did just put a new bios on but again with the 970 boots fine.

BTW not ideal but did try in my old system using a 550w psu, nothing either.

I'm having issues using mine on a riser off a x570 board (NZXT H1 case), two separate pcie power cables.

Moved it to my outgoing PC (no riser) and although it
had some visual glitches in the bios like parts of the screen jumping around, I reset the BIOS and done a clean install of Windows. It has worked and have installed the Radeon drivers, will test a bit more and move it back to the case with a riser.

Ahh forgot to answer mines not on a riser. I'm not sure I want try 2 diff pcie cables again, have to tear apart my comp to hook it up ie psu.

 

[djxput]

Someone said this to me before I got mine

Checked with my old card the resize bar is disabled.

 

[djxput]

this might sound weird, can you hear it booting into windows despite not showing anything? I had a similar issue on my 6800XT but was able to resolve it by taking the battery out the pc, leave it for a couple of minutes and put it back in.

hmmm well I sent it back and getting a new one maybe today ... I know the card felt warm so there was power getting to the card; I dont know if it was booting into windows - I couldnt tell. None of the ports showed any picture with anything ie bios or boot screen let alone windows. Didnt try the battery thing - lets hope the new one works.

will be putting mine in later today

but the display port problem happened to my rx5700 after the last driver update something to do with the monitor going to sleep

My old 5700 did have black screen issues but I think it was a driver problem because I noticed it much less when they started updating the drivers and acknowledging the problem ... but this was errr 4 months ago~

 

[djxput]

Just to be clear, I gather the people who have been able to resolve problems with bios updates or by setting the PCI-E gen manually and using different cables etc have all had cards that actually did power on, but had no display output. So it wasn't a case of the system flat-out not powering on at all such as mine did ?

Also when I say power on, I mean the whole system not just the card itself, as in the presence of the 6700XT in the PCI-E slot stopped the system powering on at all, it was triggering the PSU fault protection I would say from the little click it would give after the power button was pressed.

ya not sure my system didnt power on either ... I dont think doing the pci-e gen 3 would do anything unless like it was mentioned for a riser cable but thats specific to that.

What have OcUK said to you about a replacement then and did they give you any time frames ? They received mine back yesterday and should be testing it 'soonTM'.

I dont know anything yet, thought I might be getting a replacement today but not sure. I know when I talked to them previously I think the replacement would be out soon from what I gathered. Hopefully you will get a new one back soon and it works.

 

[djxput]

No, I didn't say that, I just said different cables, I did not specify which cables, what I actually used were different displayport cables, not different PCI-E power cables, I have actually never used aftermarket PSU cables.

Edit: Sorry on rereading that I think I may have come over as a bit harsh, I'm just really easy to annoy right now, not your fault, you're right anyway. I work in IT Infrastructure and the support desk where I work have managed to annoy me more than once already this morning by not actually reading exactly what I have said but thinking they know what I am saying and paraphrasing me and leaving out important points or trying to summarise and missing the point entirely, but hey without them I would have to talk to people I don't want to so I'm still glad they are there.

not the op of the comment but your it department and my wifes should go have lunch because she often gets frustrated with hers also.

 

[djxput]

You mention trying different PCIe cables in your posts... ONLY use the ones that came with your PSU! Pinouts vary- I've had a system 'play dead' before because I used some fancy braided PCIe cables from another PSU. Just nothing, like the power wasn't on at the wall.

EDIT not OP, sorry! But point stands...

Might of been me - I tried different pcie cables - for the same psu but different cables just to see. I have 2 cables each with 2 6+2 pins coming out of them. At first I tried both cables from 1 pcie cable then tried one from each - but I had to monkey around with the other wires because of how my psu modular works ie had to move the cpu cable to a back one etc (even thou I have a big case its a real tight fit with this psu under the shroud etc ...

 

[djxput]

So I have word back from OcUK today, well an automated email at least saying my card will be replaced so it's been tested and accepted but it just says when stock becomes available, hopefully I get another email today saying it's been dispatched ....who knows, this is frustrating as heck though. Why can't a person contact me and say your RMA has been accepted and this is what we are going to do and when or the same but we haven't got a means of replacing this right now so here are your options sort of thing.

Did you give technical support a ring? I think when I called them they told me at the time they had some cards available (as far as replacements) but this was last week. I found them pretty helpful, I know its pretty frustrating and upsetting waiting so long for a gpu and then getting one and it not working. But it helped speaking to someone that was nice. Hope it gets sorted.

Got my replacement card this morning, just running it through it's paces now, not had any issues so far, seems nicely made, quiet and I have't noticed any coil whine yet, but to really notice that on my old card I had to sit on a menu in Elite Dangerous or Warthunder neither of which I have fired up yet on this one.

Hey I got mine also ... wondering. Im trying to give 3d mark timespy a whirl and I get a driver time out everytime - reinstalled windows and latest beta driver and my mb bios etc ... can you give timespy a whirl to see if yours can run it (its the demo version from steam).

 

[djxput]

Yep, already did actually, I have the full version and it was fine, I've run it through Shadow of the Tomb Raider benchmark twice aswell and played Warthunder for a bit on it, all fine.

This was after install without any kind of tuning using 21.3.2 March 29th drivers.

Screenshot

Thanks - I have a feeling its something with my memory - I had it set to xmp1 and thought Id try it without that and timespy worked fine. But obviously its running much slower now 2200 speed instead of 3200 maybe I am not doing something right.

 

[djxput]

Are you using resizable bar at all ? ...I'm obviously not being on Intel but if you are, try disabling it and see how it is perhaps.

OK don't think I am but I'll check

 

[djxput]

I heard the .2 drivers are iffy so im just using the .1 drivers for now which introduced drivers for 6700xt cards.

Do you think that would make it so if I have no xmp profile it runs? But if I do it doesn't? (that is the. 2 drivers)

 

[djxput]

So I take you your replacement was fine and your original was indeed faulty judging by the above comment.

You are now using two separate PCIE cables to feed the card ie PCIE > 8 pin and PCIE > 6 pin and not PCIE > 6+8 pin.

I was able to send the fighter back and get the nitro, I assume the fighter was dead, I only know that they are going to give me a refund for the fighter - didnt tell me if it was indeed broken. The nitro booted up fine with the same pcie cable 8 and 6, if I have to test with 2 different cables Ill need to tear my system apart again (dont really want to do that), let me put it this way - in order for me to connect 2 pcie cables I need to take off my top radiator, 1/2 way take out my psu, unplug some cables, and plug some in and plug a different cable into the mb cpu power ... anyways its a real pain ... but I will if this is the problem.
