Question Does anyone still make a USB DVD ROM drive with no writing feature?

If you wanted to operate a live secure environment, with no prospect of data being written to any medium . If you have a reader only, this is an added layer of security.

Question hacking a webcam?

The problem is they have stripped most of the drivers from the system for anything that they have not installed themselves. As an example, most of the generic printer drivers have been stripped from the system.

Question hacking a webcam?

I have a HP Elitebook 840r G4 laptop running windows 10 which is provided by my work. I hate squinting at a small screen, so have the laptop hooked up to a 27 inch 4k monitor via usb C (LG 27UL850). I am happy with this setup, however I have to frequently use the webcam for meetings. The problem...

Using 1 flash drive for backup image and restore tools?

can you use waterproof headphones or waterproof mic with a phone?

There are now many phones on the market that offer a water submergence rating. From what I understand, some of these phones have a 3.5mm jack that is sealed to prevent water ingress inside the phone. But can this jack still be used when underwater? I ask this in respect of: 1) There are many...

Xeon X5470 overclock help

Sorry you were right, the maximum is 9x, I got confused. If you put it to 10X, nothing happens and it even underclocks to 3ghz In the end I went for the FSB of 400, but had to increase the voltage a little on the RAM. I left the CPU voltage at 1.35V. With these settings I have run OCCT:CPU...

In testing I found it more stable if I lowered the FSB and put the CPU clock Ratio to 10. By putting the CPU Ratio to 10, am I doing any harm. Will it fry something?

USB C trickle charging a laptop?

Many laptops now have the ability to charge by usb C, but many of these seem quite strict in their requirements. For example I believe the Dell XPS 13 still needs around 20V at 3A (even when off) or it refuses to charge. I believe the Macbook also requires relatively high power before before...

What is this connector?

Thats what I thought, but it does not seem to fit the plug in the second picture (without forcing). Maybe lifter is correct that some of the molding flash didn't get cut away, although I can't see where it is catching. Maybe I will take a dremel to the male plug and grind a tiny bit of...

I purchased a generic Chinese USB 3.0 expansion card. It does not come with any instructions. I was wondering what the plug is on the back of the card that I have drawn a red box around? At first I thought it was to connect a USB 3.0 front bay, but the plug does not seem to easily fit the...

Fastest USB 3.0 or 3.1 expansion card for old motherboard?

Just curious why you said this, as you are running the PA31 on your ASUS RAMPAGE FORMULA (which only has x1 spare slots) and you report how pleased you are with the performance. You actually said "It actually outperforms the native USB 3.0 ports on all other computers" Out of interest do you...

Fastest USB 3.0 chipset for expansion card?

I am currently looking for the fastest USB 3.0 expansion card to place in my old GIGABYTE GAEP45UD3R motherboard. From my research it seems that NEC and Fresco chipsets are the main contenders. The problem is most of the chipsets are very old. A lot of the cards use the NEC uPD720201 chipset...

Fastest USB 3.0 or 3.1 expansion card for old motherboard?

What do people think of this? It's a 3.1 card for x1 PCIE. Obviously you will not get 10Gb/s, but they advertise 5Gb/s. I doubt you would get 5Gb/s in real world usage, however do you think it is likely to be faster than many of the older USB 3.0 cards? It lists the Chipset as Renesas...

That's for your reply, but I think that just works like a crop. See this video: https://www.youtube.com/watch?v=7wtUaZXNr8Y I was looking for something that would just automatically detect the holes and remove them. I know such software exists as some scanners even ship with it.

That is very impressive. What was the name of the card? Do you have an amazon link to it? I know the bottleneck is the PCIe 2.0 X1 and know it is impossible to get 10Gbit, but again I stress different cards by different manufacturers perform differently even though they have all been used on...

Fastest USB 3.0 or 3.1 expansion card for old motherboard?

The thing is PCIe 2.0 x1 has a theoretical limit of 500MB/s. I know this is the theoretical limit and this would never be achievable in real world situations, but I feel 300 - 350 MB/s should be achievable. In my testing I know that all USB 3.0 expansion cards are not created equally. A while...

Fastest USB 3.0 or 3.1 expansion card for old motherboard?

I know they do, but I have not found a USB 3.0 card that saturates the PCI-E x1 slot. in fact most of them don't come anywhere near of the x1 capability in terms of speed. My question was if any of the USB 3.1 cards are likely to get nearer to saturating the USB x1 slot? Will they perform...

fastest CPU you can buy for socket 775 motherboard?

Yes I know it needs modding, but my question is - is the xeon x5470 the best option in terms of speed and cost? It seems it is much cheaper than the Qx9650 and is just as good at overclocking. Or would you suggest another option?
