R9 290X PCB breakdown + power and voltage mods.

[@jhonyeryc]

you have schematic r9 290x ? HELP me

[@paublusamericanus292]

what I would like you to do like this is a gtx 1060. and show the 1.5v memory bus. show the 3.3v gate bus. the 5v counter bus and usb, and 12v bus. that would make me able to do just about whatever with trouble shooting, without a schematic. Your videos are so clear and concise even I could understand it. you may only do radeon, but to me they are so similar, even the counterpart radeon would probably work.

[@goa48]

Great vid as usual, never had an AMD card before but that PCB looks beast compared to the newer nVidia ones. You mentioned that the EVGA Classifieds use a similar mosfets. I would really love to see a PCB breakdown of the 980 Ti Classified if you have the time for one and good quality pics are available. Keep up the good work!

[@mariopic2625]

got a xfx 290 that had a cap fail on back side near the vrm no clue what whould cause problem also wondering if it may be posible to repair ? and how to test for more damage to card

[@KaZuAltY]

This video makes me want to voltage/power mod my GTX580 Hydrocopper 2... Hmmmm. :D Thanks for another great breakdown vid!

[@GabenHood]

After doing a DIY cooling solution to a second hand 290X I picked up it seems I missed cooling the topmost smaller mosfet in your image. (IFR6811?) The card will not let my PC boot anymore and a black marking on the top of that mosfet is the only damage I can see with the naked eye. Do you know any cheap tricks to make the card work again?

[@adriancheudan5592]

You mention at a point to put a temperature probe near the VRM. Isn't the software readout correct from GPUZ? I am asking because I change the cooler of my 290x because it was too loud. The problem is that I now with the watercooler I have random black screen but only during high gpu usage. But even in games like smite I get black screen. Gpu temp does not go over 50 and VRM1 stays bellow 70 and Vrm2 bellow 50. These temps I get in games. Right now I run FurMark (GPU - 62, VRM1 - 88, VRM 2 - 58). And no crash!! So it looks it is not temp related. I play games in 4k. I have tried differetn power supply. Separate power cables, lower , higher voltages.. and lower or higher gpu speeds. I seams that the GPU speed is not related to the event. Now it is stable but with a mem clock speed of 1000 Mhz.. that is 250 mhz lower then default. Gpu is at 1000 as default. Any ideas? Furmark does not use only 702 MB of VRAM..

[@kayburcky7146]

I flashed PT1 on my water-cooled 290x and i can't seem to get the GPU tweak to work. I think it's interfering with Radeon software because the core clock gets reset every time I try to apply it... Only voltage doesn't immediately jump back but I can't seem to find any difference in HWinfo in terms of voltage 🤔

[@hiephoi058]

question, does the ir3567b need a heatsink?

[@jameschapman7759]

anyone know where i can find a working link to the PT1 bios spent a few hours trying to find it with no luck

[@terrorjerry]

i have no luck finding it. If you find it maby you can tell me were to get it?

[@NaXter24R]

Do you think the back of the card needs some additional cooling? Right now I've water-cooled the card and I would like to push it. I think that on the back there are all the drivers. I would like to cool my vrm a bit more so I was wondering if cooling the back might help or not. Also I don't know where vrm1 probe is, that's why I'm asking.

[@ActuallyHardcoreOverclocking]

All the driver FETs are on the back of the card but they really aren't important to cool. However the 6894s ans 6811s do dump a lot of their heat straight into the PCB so some thermal pads on the back of the PCB with a heatsink could improve VRM thermal's.

[@NaXter24R]

Actually Hardcore Overclocking Thanks a lot mate! Il planning to get some backplate, like EK or Aquacomputer (passive). Even 5°C could justify that investment, 30 bucks is something i can afford :)

[@Rourkeize]

Get the Aquacomputer backplate. Lowers the VRM 1 temperature tremendously. Expect 20° drop at least when water cooling.

[@NaXter24R]

Wilhelm Sundström You mean the active or the passive one? I was thinking about the passive one because i don't know about compatibility with XSPC waterblock

[@Rourkeize]

Yes the passive one. I got it with a Aquacomputer waterblock. If you modify your bolts it will probably fit with an XSPC block as well. The active one gives the best temps at a cost of slightly higher core temp. But it only fits with a Aquacomputer block since the terminal is linked with a heatpipe to the backplate.

[@gazzilionDucks]

Hey, talking obscure cards, could you do a GTX780? Also it would be nice if you considered making a video about differences in sibling cards like r9 290 - r9 290x, GTX780 - GTX Titan and such.

[@ActuallyHardcoreOverclocking]

+Jeremi Świerczyński R9 290X and 290 are 100% identical. The GTX 780 and TITAN also share PCBs.

[@BrickwallStudios0]

I just found your channel and i enjoy it so far. I have R9 290X Lightning, and it have all voltages unlocked in Afterburner, even Aux, but i never knew how Aux voltage could help me with my OC ?

[@ActuallyHardcoreOverclocking]

Aux can sometimes help a little with memory clock but generally it's completely useless.

[@BrickwallStudios0]

Actually Hardcore Overclocking Ok tnx :) I just set my memory on 1500 without touching Memory or Aux voltage and it's fine

[@gsmgsa]

Hello! Could you please tell me what happens if the high site MOSFET of the extra voltage phase is gate-Source shorted (not in itself, but in its driver NCP5230) ? I would consider it as the 7th phase, also I don't know if this is the actual numbering as I do not have schematic. I have a problem with a R9 290 4GB 7 phase graphic card that only supplies voltage to Memories, but not to GPU! Is that some sort of protection the controller uses in such cases and phase 1 to 6 are not activated by IR3567B? Thanks for clearing it out!

[@Antoniovieirafreitas]

meu é inverso

[@gupsterg6171]

IR3567B controls VDDC and VDDCI (AUX), this is what I get when click "i" in MSI AB i.imgur.com/TsatQkQ.jpg . This is also highlighted by Unwinder author of MSI AB and by The Stilt. When viewing Shammy voltmod guide it show VMEM measure on rear VRM and VDDCI on front VRM, so is front phase VDDCI or MVDDC? and what about 1 phase on rear VDDCI or MVDDC? Then VMEM adj volt mod is differing location to your information. Any chance of clarification? cheers

[@ActuallyHardcoreOverclocking]

It's been ages since I've had a 290X in my hands. But I'm pretty sure that I got memory voltage control from the 3567B. As for the location of the memory phase I'd trust Shammy about it. I'll probably have to redo this video once I have a 290X on hand again.

[@fightinirish73kk]

have a question watercooled my sapphire r9290x vaporx it overheates to 98c and screen went blank restartd gpu not detected no video is my gpu fried

[@ActuallyHardcoreOverclocking]

sounds like it probably is

[@fightinirish73kk]

well shite thanks man

[@Zyzz710]

strange. considering that it supports up to 95c, Fried just for other 4°c?

[@jakubmatousek9429]

Sounds like fault GPU. My R9 290x throttles at 94C no matter what. Solved my thermals with aftermarket cooler + spacers on the back. The cooler was not quite touching the die.

[@Kakoe]

Hey i have a r9 270x, when i install drivers i get a black screen i have tried it in other pc's but it does the same thing, Do you know if there is a FIX ? thanks

[@inoahmann7542]

You can try refreshing the card bios. It is a risky process but if want to take that risk I think Jayz2cents has a good video on doing that. In that video I think he repaired a GTX 980 ti.

[@supertramp1079]

Great video. What do you think about that Sapphire 390 Nitro pcb btw? Core vrm looks a bit different to me, also different mosfets. www.overclockers.ru/images/lab/2015/07/23/1/03_big.jpg

[@ActuallyHardcoreOverclocking]

I do believe I mentioned that the 390X and 390 PCBs no longer use the 6894+6811 combo but use PowerIRStages to get better efficiency.

[@ActuallyHardcoreOverclocking]

I'm not sure where the sensor(s) is. Also that MSI PCB is not the 290X layout. It's using doublers for Vcore.

[@supertramp1079]

But the mosfets are same right? Which design approach you think is better between the Sapphire and MSI?

[@ActuallyHardcoreOverclocking]

The Sapphire is using 60A PowerIRStages. Those will do better at high temps than the 6894+6811 combo of the MSI. Also the MSI is doubled and has a smaller capacitor bank so the Sapphire should be significantly cleaner. Power wise the Sapphire is weaker at lower temps but at high VRM temps the Sapphire should be stronger. Also the Sapphire VRM should be more efficient. For and water cooling the Sapphire is the better design for LN2 the MSI might be able to push just so much more power that the other differences don't matter as much.

[@supertramp1079]

Thanks a lot for the answer. Really informative.

[@dermarius87]

Hi, I'm messing around with coil wining repair on R9 280X cards this time, do you know a better, non-wining replacement inductor type which fits on the PCB?? I've just found the Coiltronics / Eaton FP1007R3-R15-R ones at Mouser: www.mouser.com/ProductDetail/Coiltronics-Eaton/FP1007R3-R15-R?qs=GxOUx7aO6nyJQ1rFPWaMUg== Should I just use these ones in the hope the wine is fixed replacing them with the same part, or could you recommend another fitting one? Furthermore: I've a Gigabyte R9 280X Rev. 2 here, which is only detected as PCIe x8 instead of x16. www.techpowerup.com/reviews/Gigabyte/R9_280X_OC/3.html Do you know which part should be responsible for that? Maybe that's just a resistor to be replaced? Thanks so much for you work, highly appreciate what you're doing.

[@imfromanotherplanet]

Can you take a look at the GTX 980 Ti G1 gaming PCB ?

[@ActuallyHardcoreOverclocking]

This one?: www.techpowerup.com/reviews/Gigabyte/GTX_980_Ti_G1_Gaming/3.html

[@imfromanotherplanet]

Yea that one :) i just bought two used once and i wanna know from one with better knowledge then me , how far i can push it with water :)

[@LevyMorFit]

do you know if its the same as the gigabyte r9 290x pcb? and if not can you do a video on that one too? thanks

[@ActuallyHardcoreOverclocking]

They are the same

[@LevyMorFit]

u sure? look at this photo: www.google.co.il/search?q=gigabyte+windforce+r9+290x&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjl7Ji2xq3NAhXRERQKHdXMDIQQ_AUICCgB&biw=1440&bih=775#imgrc=5EqbVDqHoyLnuM%3A it doesnt have the line of round pink things near the memory as the reference card has..

[@ActuallyHardcoreOverclocking]

the layout is tweaked a little but still the same.

[@LevyMorFit]

ok.. so im assuming that a reference cooler or water block wouldnt work with the gigabyte one right?

[@ActuallyHardcoreOverclocking]

According to EK their full cover 290X waterblock will work. I'd expect the stock cooler for a 290X to also work

[@Crysis9800]

Hey, where can i find VRM schematic for the 5970? Card wont post and 2 red led lit on the back. Checked vcores and nothing only a 3.3 voltage was measurable on the Vdd pin on the Pm25LV010 chip

[@ActuallyHardcoreOverclocking]

+Crysis9800 The Pm25LV010 is not the Vcore controller. The Vcore is done by the VT1165MF. Datasheets for the Voltera VT1165MF aren't publicly accessible. I think you best bet would be to try externally powering the card and hoping that the card won't miss the PWR_OK signal.

[@Crysis9800]

I know that these voltera datasheets are not publicly available and the Pm25LV010 is the flash controller. The card does not warm up so maybe is a defective bios or has nothing to do with that?

[@ActuallyHardcoreOverclocking]

+Crysis9800 A defective BIOS would still boot the VRMs.The only way a VRM won't boot is if there is something wrong with communication between the GPU core and voltage controller.

[@Crysis9800]

I measure ridiculously low resistance between vcore caps.. wtf is any short? About 1, 2 Ohms. If you could measure the HD5870 and tell me the values. I was wondering to power up with an external powerboard and go nuts.

[@ActuallyHardcoreOverclocking]

+Crysis9800 That's normal. The circuit looks like: Vcore >> GPU >> GND. GPU cores are really really low resistance when turned off. My GTX 590 had a resistance of 1.2Ohms Vcore to GND.

[@phatboycd1]

Love your videos. anyone know a website or video that will show me how to test for short on my asus 1080 turbo. I beleive it has a short ,powers on and no video and my intel board beeps twice. Thanks in advance!

[@McHumaty]

Make for 8400GS...
