Re: Graphics cards: PCIe 1.1/2.0 16 lanes showing as x8 or x4 in modern motherboards

There are PCI-e bandwidth benchmarks : 1) First one is in AIDA64 (under GPGPU benchmark , NOT "Cache and Memory"). Results for "Memory Read" and "Memory Write" will show PCIe speed (uplink/downlink), while "Copy" is VRAM test (requires DX10 or later card). 2) Another option is 3DMark (2013) that …

Comodo started quarantining my pdfs for no reason. I could find them except with W10 file explorer (or whatever it is called). It took me 6 hours to figure it out. Strange thing is that the generated files via the blocked program couldn't be found even with Linux. Like if they had some attribute …

I'd like to further the topic but on a dedicated forum. Any suggestions? No. I have been on the internet for 25 years, VOGONS is the only forum I recommend. Helmet on, let's soldier through this :) Is there a program that can benchmark bandwidth? Maybe it's just misreported numbers. 4x or 16x but …

I thought that speed and links were independent from any drivers. Unless it's a Gpuz and HW are both wrong at the same time. When you run GPUZ, there is a "?" next to where it says "bus interface". Click that and run the render test... Does your PCIe speed change when you do this? Mine shows @16 …

I got a ryzen 5900 a few years ago as my 'it's time now' upgrade, because it had the best bang for the buck. Never did understand the chevy/ford like dichotomy some folks have for intel/amd. Neither has my loyalty. I tend to go for whoever has the most efficient CPUs that dont compromise on power, …

I tested all the cards I have on a 4th gen i5. Before drivers I got odd link reports: 2 x 2.0, 4 x 1.1... After drivers all checks. I thought that speed and links were independent from any drivers. Unless it's a Gpuz and HW are both wrong at the same time.

I tried everything but no change. Force Gen 1/2/3... no change, lanes stay the same amount. With all the changes even on cpu support with newer BIOSes, I wonder if it is indeed a compatibility issue. On my ancient Ivy Bridge board, I have to manually set my PCIe to Gen 2 on one of the lanes or else …

One more thing I checked is the actual presence of lanes on the video cards. My 1050Ti is (16x 3.0) but only has 8x on the PCB. This is one thing to take into account. But the others all have 16 lanes. No missing caps or res on the lanes.

Fire Gl is @ 16x 1.1 - works @ 4x 1.1 Other cards 16x 1.1 works @ 8x 1.1 2.0 same @ 1.1...... Is this a compatibility issue with old + new? I'll test all these cards on PCIe 2.0 and 3.0 boards on i7 4th gen to check if it is. Do you have an option in the BIOS to force which PCIe generation is used …

Hello!! Yesterday I was testing a PCIe slot on a new mobo I acquired. Am4 B450M chipset. PCIe is 3.0. Slot #1 is connected to the cpu, GTX690 is @ 16x 3.0 - slot works RX580 is @ 16 x 3.0 - slot works Fire Gl is @ 16x 1.1 - works @ 4x 1.1 Other cards 16x 1.1 works @ 8x 1.1 2.0 same @ 1.1...... Is …

Thank you, will do tomorrow. If i find them to be dead would a BDW93C be a proper replacement? All parameters appear to be the same except it only has 12 Amps collector current rating instead of TIP102's 15 Amps. Not sure if that matters that much. https://www.tme.eu/Document/ …

I had 2 boards with dead TIP102. Probably you have to replace them. You can desolder them and test. https://pdf1.alldatasheet.com/datasheet-pdf/v … OLA/TIP102.html

would you try with a cpu in? I have another QDI and they give that reading without a cpu but correct with one in.

The 2 components wiht heatsinks are responsible for the Vcore and Vio of the cpu. Measure those without the cpu in. Your board is single voltage cpus only , Being dual voltage test different voltages: I/O it should be 3.3V and Vcore whatever ypu set it.. They are Vcc2 and Vcc3 on the socket …

It looks like someone has used extreme heat to reflow the chip, although the chip internal resistance still looks good after that heat abuse, mine has dropped to 50 ohm. at this point you need either to properly reball the chip or inject lots of flux under the chip and reflow it again and hope for …

Close to 4-pin header, check the sop-8. Maybe it's nothing. Do you mean the 4 pin header near the molex connector? Yes. There is a little sop-8 chip. Look what it is and maybe it is connected to mosfets. Just a guess. Maybe it's nothing at all. Tha fact it powers on immediately means to me that the …
