Speed Issue

[Dfaker-HK]

I recently bought screamer dma, and I tried to test it out through dumping memeory on pc, but then I found out that the speed is very low(70mb/s), then I tried to switch cable, pcie slot etc. all dosent work, but when I switch the pc running pcileech, the speed just become normal(>150mb/s), at this point, I think maybe it is the pc problem, but the first pc I am using is a i7 8665u and it's cpu usage dosent come to 100% when I run mem dump, is there any possible mistake I made so the speed is so slow?

I agree this is quite slow. But it's fast enough so it's not an issue with the USB cable.

Are you by any way dumping to a slow HDD?

Also performance on Linux are slower than when running PCILeech on Windows due to driver issues.

if you suffer from speed, and got only half of the speed, like 70mb/s, check if you are using gigabyte motherboard, I switched the motherboard to Asus its normal again, don't use gigabyte motherboard, repeat, DONT USE GIGABYTE motherboard!!!

I'm closing this issue due to old age and since I haven't heard back on the issue I trust that it's resolved.
