post #1611 of 3464
@chris89 hey thanks for thinking of me with the new bios... is this one going to make the fan calm down a bit? lol I think my card ran fine with the mem clocked up to 1850, should we set the mem there permanently? will try the new bios tmw thanks!

@pok123

Your welcome yes I just made the card ultra quiet ... Its all about the temperature of other chips on pcb... gotta keep them cool...

Plus overclocking ram isn't advised if your card is not cooling the Memory Modules or VRM directly... As many are not... Can easily burn your card up in seconds literally...

So it's important to know if your card cools the Memory and VRM directly.... Reference RX 480 does all of this .. and does fine by stock but if u add the extra pads to memory VRM, Master Voltage Controller IC, and other metallic VRM... Then you can get insane numbers of it haha

*Realistic Do-able clocks*

4GB Cards (all of them) 1797Mhz max really no more is ideal

8GB Cards (non-reference) 2067Mhz maybe more with tons of errors (millions & millions)

8GB Cards (reference) 2267Mhz probably no more but maybe never tried... only 70 errors at this clock

here one on the sap rx 460 4gb stock, planetside 2 1600x900 med settings. fps in the top left corner althou this drops to 40 fps in big war times of like 100+ vehicles and air etc but to keep at 60 fps it does well.

Thanks Chris, I'm not stable with either. 1.23 v for 1376 doesn't work, I can do 1330 at this voltage and not crash.
I swear my chip sucks.... low temps below 70, running 1.15 sometimes can't even pass the default 1288 load is low, like 70w normal vsync gaming, it will randomly bsod.
As soon as I drop the top clock to 1260 or 1270 it works fine. So pretty much the stupid factory overclock is not stable on this garbage asic chip. And it still says 65.1 despite having changed my psu. It's funny it says my asic quality is higher than 5% of the cards in database. That means 95% of cards have better asic. What junk! It's like the lowest binned part. Meanwhile guys are doing 1280 easy on way lower volts!

This XFX RS rx480 is garbage... I should rma it but they might say it passes if they don't run the stressing games that make it bsod. then what are those jerks going to do, send me back the same crap card? SO ANNOYED.... because its factory overclocked and can't even stay stable at that!! And their RMA policy sucks because they have to test it, while I wait. I liked gigabyte they had a good advanced rma process... pay , get card, send back old one get a refund. I'm not even sure doing a RMA is worth it. Just again, pissed that their "factory OC" is unstable at the bare limit...

RobNitro_1267Mhz_Try_It.zip 110k .zip file

Your welcome robnitro.

Try this it's stock voltage : 1267mhz core : 2000mhz memory : stock 65288 voltage : 88 Watts Limit/Max & 88 Current Ampere Max : 80C Max/ Hotspot : Shutdown 88C.

Reduced low end clocks so the low end voltages will use less voltage...

BTW - My xfx 460 dual fan had ASIC 50%, literally 50%... but it did fine at 1267Mhz, not delimited though... The VRM would get hot. After I dialed in the fan it would load out 63C and run perfectly.

XFX RX 480 RS looks like reference so its most likely the VRM is overheating since it uses that ultra low quality vrm material... but VRM material no one uses the good stuff... Only 290X saw Fujipoly 17w/m K but the application is horrible and VRM hit 100C ...

XFX RS 480 has 14 Core VRM compared to AMD Reference 20 Core VRM... So each VRM takes on more load, therefore is way hotter than Reference. Take 20 divided by 14, that's 42.86% more load per VRM than reference. Meaning the VRM is 42.86% hotter at all times... Need epic thermal material/ performance or a jet turbine blower and maybe a freezer to throw the gpu in on a 10 foot long PCIe Extension hahahahaha Teasing ... Or Use My BIOS and be Happy biggrin.gif

So it looks like XFX uses really high quality PCB components, it's just their "GAP" between the VRM heatsink and VRM is too much. Not to mention VRM Pad of Low Thermal Conductivity and Way Too thick meaning thermal resistance and lots of it. Thinner pad has less thermal resistance etc etc I've gone over this a million times.. thermals is like the easiest part of engineering and is Eagerly overlooked and rushed like Thermals are nothing of importance.

Thermals are #1... Or the card will be thought of as Junk...

So it takes Patience plus High Quality material to yield solid thermal performance.

I'll try later, working on figuring out why one of my injectors died on my car frown.gif

I doubt it's the VRM's because it can bsod at the lightest load, like I was sitting at a rest stage in dirt rally, using 50 watts or so and got a BSOD. I didn't know at first just saw my computer rebooted!

Once I put the max to 1270 it didn't do it anymore even when I loaded it up and HOT with occt. So this basically is my crap core limit. Is it worth to rma, I don't know.

Just so you know when I first got it, I couldn't get occt error free past 1275 or so 1.175. I was annoyed but hey occt is hardcore (even more than furmark). Only after 2 months or so it started to bsod in normal low load apps. So the chip is a dud and occt knew it way before!
Oh and today, it's still stable in occt even hot, high load 1270 1.175. But since factory is 1.15 and 1288, thats unacceptable, their own clocks are unstable. I wonder how many more people face these issues and think it's the driver, etc!

@Mgrandy haha that thing could probably handle 500 watts of cpu power

@robnitro yeah BSOD happens because the default temps on the default bios are well over 100 degrees celsius.

If you have always had BSODs on always running stock BIOS Temperatures, then if you remain using stock BIOS temperatures all BSODs will remain.

We can only avoid BSODs if we reduce these temperatures, to levels at which no BSOD occurs...

Depends on your BSOD if it's atikmdag.sys or a Specific AMD BSOD then we can point at the Radeon. If it's something else like Thread Stuck in process chain yada yada yada. Could be lacking memory module timings or memory errors occuring.

Try IntelBurnTest at 128 threads, max memory usage. Run it through 3 passes (up to 10min per pass). If it does not succeed on 3 measley passes then you have memory errors in system memory or corrupt sector bit in HDD or faulty secotor bit in I/O devices ie HDD/SSD. Run Windows Memory Test "Start type Memory Test" and Run full Disk check correcting Sectors... It can't be done properly in Windows 10. Only Windows 7 corrects the sectors properly. Windows 10 just glazes over quickly in a hurry fixing pretty much nothing in the couple minutes it takes. Full Disk Check takes hours and makes a big difference if the drive was filled.

What I would recommend is using "Electrical Contact Cleaner & Air Duster" and a perfectly clean toothbrush. Clean each DIMM Memory modules slot so the "Gold/ Copper" contacts shine. Also use Electrical Contact Cleaner in the CPU Socket if AMD? Heck do the same for intel (Contact cleaner on pins brush with the Grain not against Obviously lightly). Clean all contacts on the Modules and Slots for CPU and the CPU itself. Make sure contact is so flawless.

Since I have had recently issues with my other xeon on the riser... The riser cuts out every so often... First it was dust in the Memory Module slots, now dust/ dirt in the Riser connection itself. So I need to do the same to use all 24 threads and 48 gigabytes of ram.

This "Dust or Dirt" is not visible to the eye, you cannot see the dirt or dust. Yet the connection is not there. So cleaning will ensure a proper operational connection.

Hey chris here's results with your new bios top card is still undervolting and downclocking I'd like to add I noticed the original .153 bios temp settings are 90,94,105 if i use those bios and only change the tdp,tdc,max power to 999 then it will run 1303 core 2000 mem like intended but the voltage has some high spikes vrms get hot but until it reaches 89 degrees both cards stay 1303 100 percent. Anyways here's some 4k time with shadow of mordor on your new bios with clocks and voltages still dropping on top card also this happens immediately regardless of temp.

a jpg screenshot would be helpful... yeah it's annoying that a bios simply can't be thrown on a card... a bios needs to be specifically designed for a specific brand and model of card...

I would need all the rx 480 cards to make bios for each .. that would be nightmare because only reference can hold top position as I know from testing.

Jeztur2003_1333mhz.zip 110k .zip file

Reference Visiontek can easily handle 1,407Mhz Core clock on stock voltage. Only because of Epic Reference VRM Cooling. Gap is nice, could perform better if knocked down to 0.25mm gap from 0.5mm gap. That 0.25mm, could be as much as 2-3,000 extra points. Gap is important. It's like if the Core had a 0.25mm gap between the core and heatsink... It wouldn't touch... Then to think you could transfer up to 220 watts through 5w/m k paste is not possible... Need No Gap Ideally... the VRM sits Flat on the heatsink with no pad in place... Place 0.25mm pad or thinner for VRM and have nearly perfect cooling on vrm... same for memory modules etc etc etc... thumb.gif

I had a 380X Sapphire Nitro and it had a huge VRM gap that made the VRM's overheat on a Continuous Basis, Always Overheating Under Load All The Time.

If only there was a 380X Reference available wouldn't have the issue but no Reference 380X Exists... Except in AMD's GPU Vault ... which for me is like a kid in a candy store drool.gif

*Note To All AMD GPU Suppliers*

Have the fins Facing the Proper direction.. out of the back of the exhaust of the case not towards the PCIe slot etc. We don't want to dump all the heat inside the case, we need it to go out of the case.

Have no VRM gap at all.. provision no gap from heatsink to VRM so whatever cheap pad is used. Performance will be optimal regardless of material because of Compression the pad will merely be a "Bonding Agent".

They could even go even Cheaper and save more production cost by using Mass Bulk thermal glue. With no Gap from VRM to heatsink... Add a tiny dot to each vrm and bond it when screwing down... However many dots for as many VRM's as their are.

That's like 1 micro ounce of thermal glue needed when no gap exists. Which would cost $0.001 per GPU for VRM cooling and far superior VRM thermal performance as well... If they all went DeLimited, the cards would be unreal.
