Polaris Bios Editing ( RX5xx / RX4xx ) - Page 43

post #421 of 3315
So you're saying for safety I should get a pci extender cable with a supplemental power connector... Have to think about that. That would require a case mod.

While you did no such thing, the poster called me "crazy" I thought I had an educated reason for believing it could handle it. If you're saying I'm wrong, it still doesn't make me "crazy"

edit: There's a discrepancy between the theoretical spec and what the experiences of people say is possible. I admit I've been out of the industry a long long time.

2nd edit: what about the 4 12volt pins on the 8pin eps? Is that all for the CPU? I honestly don't know.

3rd edit: I suppose at the very least I should upgrade the wires on my 24pin from 18 to 16. I have a crimper, it''s just a pain getting to my PS connector. I have a rad pushed right up against it. Sorry I got upset. I just didn't expect the other poster to call me crazy for wanting run out of spec or being unconcerned about smoking my motherboard on a overclocker's forum.

4th edit: when I was in the industry the mb eps connector was 4 pin and new. (and all for cpu) I worked for an OEM in the 90s to early 2000s.

5th edit: My 24 pin connector is warm but not hot at my current settings in Firestrike and 1.268

I pushed my board back to the smoke point on my damaged mb in firestrike ultra. 24pin was maybe 5 degrees over ambient. It's not the point of failure. Diffidently 12volt pci-express power distribution. I'll have to back off on my overclock now. But at least we know.

okay maybe a little "crazy"

1430 seems stable at 1.215 VID. I haven't run stress loop yet. I don't have time to put in my backup motherboard if it finally smokes for good.


edit: in redoing my loop I'd accidentally plugged my 8pin eps connector into a pciexpress port on my modular powersupply. I ended up needlessly ording a 2nd asrock extreme6 z97 from newegg. So I have 2. (hence my cavalier attitude.)

edit2: the powerconnectors on my powersupply aren't accessible when my system is put together. I have 3 rads and there just isn't room for 3 rads in my case. I'm also only 99% sure the other board still works so I'm still going to be a bit cautious.

edit3: would using an extender cable and splicing 2 4pin rail molex connecters and using 16 gage help? Most supplimental poweron pci-express extenders I've found only supply 12volt to 2 pins. You know of any others?

My lamptron splices 3 together using 14 gage.

How is 1.3v for the GPU? Too much/ok? This is under an AIO 240mm water cooler. Temperatures at this voltage are 43C under load (in a 28C ambient LOL).

Also, VRM temperatures, as reported by software are maxing out at 110C (I understand 125C is the rated max). Measuring with a laser thermometer I get 90C. Where is the temp diode located? Or is this digital and therefore cannot be fully trusted?

Considering I smoked mine at 1.32 something and now it smokes arround 1.28, I'd be careful. I just did a FireStrike Ultra Stress Test at 1.22 holding my 24 pin and with my nose in the case and it was fine at 1430. What's your video card vrm cooling? I'm under a full cover block and they stay in the 60s for that. On my damaged board I wouldn't go that far, but you're right under water it's tempting because the card clearly responds well to more voltage. Stupid AMD for limiting the reference card so much.

Wait, what? Smoke from where? The VRMs, I suppose?
It couldn't handle 1.32v?

Was watching der8auer's video on water overclocking for the RX 480 and he was using 1.35 and went up to 1.5v (yuuuup!) for benching.

somewhere on my Asrock extreme6. I checked all the visible chips with a magnifying glass and I can't see anything in the case. There's one near the VRMs that might have a bit of a spot on it. But my backup board has a spot there too. My backup board has some distressed pins on the processor socket from delid processor being held down by a raystorm. It's hard to get that block down even. I had misdiagnosed a stupid error on my part as being from the distressed pins. Still slightly possible there were two causes to the same issue, but most likely that board is fine. I don't have time to swap them out right now. It takes a couple hours as I don't have a fil or drain port and it's a ***** keeping water off my mb getting everything drained and disassembled. I'm doing a remodel on my house to get it ready for my father to come home from the hospital after a stroke so I don't have the time I'd like for my hobby. But torturing electronics sure does relieve some stress.

You have my respect, I can sort of corroborate the temp reading on my 24 pin connector and even the PCI-E slot, I have no way of measuring power flow, but I have an IR termomether, have been taking readings on those 2, and even at the highest overclock after 15 minutes, none of the 2 got hot, max was a 6 degrees extra on the 24 PIN and a 5 degrees extra on the PCI-E, MB VRMs showed no abnormal heating whatsoever, so I wonder how some people could have fried their MBs, I would think that even a MB that was assembled on a fishing boat would last better biggrin.gif

to be fair most people aren't dumb enough to run firestrike ultra stress loop while power usage is that far out of spec. That's like a worst case scenario test. But if it's going to fail someplace. That would be the place or maybe Metro.

mind for me to ask ?

What is the safe max temp for RX 480 full load running 24/7 ?
