# Screamer PCIe USB-C (R04)

The Screamer PCIe is a PCIe x4 FPGA manufactured and sold by LambdaConcept ([link to store](https://shop.lambdaconcept.com/)). The card features a fast USB 3.0 connection and up to 150 MB/s read/write speeds. It ships with the precompiled pcileech gateware, and a device identifier of 0666. 

There is a fundamental hardware issue with this device, however. The USB-C port sits too high on the backplate and is **very** often blocked by the case the device sits in. My solution is to sit the card at a slight angle and not bolt down the backplate (I do not recommend this). 

I purchased two of these cards, with a friend of mine purchasing a subsequent third device. Two of these three devices were defunct upon arriving. LambdaConcept ignored support emails on this topic. Essentially, there is a 50/50 chance the card you purchase from them will be non-functional, and you have no hope of getting in contact with anyone from LambdaConcept to resolve any issues you run into. 

When the card does work, it seems fairly stable even under a high-temperature environment. My functional card sits directly underneath my RTX 3090 Founders Edition and I have not noticed any major stability problems while gaming. 

Thanks to the documentation provided by LambdaConcept, flashing the device is fairly simple. Though you will need to purchase a second JTAG board in order to do so.
