looks better   :)

btw, I think everyone here in the forum would be grateful if you'd post some high-res pics of the mob (the more, the better...)

Yeah well new plan, I found the new asus ones on Ebay a bit expensive for such an old mobo. So I found this Intel one:

USB3, SATA 6GB/s, DP, lots of PCIe expansion options and the necessary PCI port for the Aladdin card, support for 2/3gen i3/i5/i7, looks pretty nice.

Using ATI video card with displayport. Nvidia no, because big current and power supply shutting down from time to time.
Adapt connector to internal use.

And add software options... ;)

I like this build and will probably do similar. One change is that I want to use a smaller touchscreen (https://www.aliexpress.com/item/33013349786.html?spm=a2g0o.productlist.0.0.de4e713a9YlFrI&algo_pvid=f23a6939-3e47-4d31-9115-11080c9b564f&algo_expid=f23a6939-3e47-4d31-9115-11080c9b564f-8&btsid=daba0ed0-6f18-4bac-b059-261c1a90df60&ws_ab_test=searchweb0_0,searchweb201602_1,searchweb201603_53) which should fit better(?).
I have quickly checked the dimensions of the gerber front plate and it seems ok to me. Has anyone else used it?

I will do them in 1.6mm FR4, JLCPCB wants about 25 USD for 5 which is much cheaper than the laser cutting. Anyone interested in the CH/EU please ask I'll send you one of my spares.

I also installed two Noctua ppc 3000 fans (140mm). Right now it's a hack with the existing fan plate cut to size. However I will get another mounting plate also made from PCB material... Together with some PETG 3D printed airducts it should work fine. As I said I'm testing it right now. I have no way of measuring the airflow but subjectively I would say it's more than with the old fans. Might be because I noticed that the old fans run only at about 0.5A instead of the rated 0.65A (in my DDA5005 are 2x Panaflo FBA12G12U installed).

Noise reduction is there but it's less then I hoped for. I would say maybe 2/3 as loud and 1/2 as annoying to me because the noise is less pulsing and lower in frequency.

So, I did the mobo upgrade on my DDA-5005 (Wavemaster 8500) and updated to Win 7 Ultimate 32 Bit.

- Intel Mainboard DQ67SW
- i7-2600k which I had laying around, only 2 cores running to reduce TPU
- 4GB 1333MHz DDR3 RAM
- ADATA SU800 256GB SSD

For Testing I installed a HD545 512MB GPU. Intention being that I could tap into the HDMI or DVI port easier than on the MOBO.

One problem I still have is that I get the error "3D Acceleration not enabled, might limit performance..." on XStream startup. However, 3D Acceleration seems to be enabled in the "dxdiag" settings... That is regardless of GPU / internal GPU...

Conversion was really easy. I did a clean install. Then installed all the chipset / mobo drivers. Then to install the xstream drivers I downloaded moded xstream drivers from earlier in the thread and installed them via the legacy driver install option in the task manager. I had to repeat it a couple times. A "PCIe Serial" driver did not install but it does not seem to be a problem. After that get the xstream 8.x from the lecroy site and it worked.

Mobo size & screw holes etc fit perfectly The clearance to the bottom is on the thight side but it just bearly makes it. The only real mod is the "front panel" pinheader which is wired differently as seen in the photos: https://www.flickr.com/photos/154275690@N07/albums/72157712362680997

So far I really like the results. For example the Spectrum Analyzer function is really fast, even with the 3D heat diagram is enabled. The scope really flies now. Also I get gigabit ethernet. Attached is a little demo of a remote desktop session.... I'm not even sure if I stick a screen on the front  :-DD

The mobo just went out of support so no official driver download on the Intel site. I have collected most of what I found and what worked for me.

Jens01:
I've recently acquired a Lecroy WR6030, which failed to start the Waverunner software. Did a clean install (W2000 -> WXP) and the unit since then worked flawless :scared:. Big thumb up for all the work already done on the forum, including the working touchscreen-driver :)

After a bit of playing around i found out this (non-a) 6030 supports 2x 5GS/s in interleaved mode, but the datasheet and the front panel suggest only 4x 2.5GS/s is supported. Only the 6030A should support this conform the datasheet. Did Lecroy upgrade these units by just updating the firmware? The unit is probably 'uphacked' by the previous owner as all the options are available including non-ordeable USB2 and ENET. The status menu does mention the unit is a 'WR6030'.  Firmware is 8.1.2.0, latest available. Did they really gave the doubled sample-speed for free or am i missing something?



The oscilloscope feels a bit slow and the fans sound like they need replacement, so i will upgrade this unit to W7Pro, S775, core2duo E6600 + SSD if i can find the right Motherboard. The combination of right chipset, available PCI-slots, AGP slot and native SATA is quite hard to find.

The unit now only has some cosmetic 'problem', the previous owner lost or broken the original front-panel knobs ( |O ) and therefore the knobs are replaced by some ugly black-red universal knobs. And not one, but all of them. Does anyone know if Lecroy is willing to sell replacements or if the original knobs (or some universal white knobs) are commercially available? I've tried Farnell, Digikey and AliExpress but the combination of grey/white + D-shaft does not gave a lot of options.
