Question about ESS Canyon3D FM synthesis

Posted on 2022-04-23, 17:22

in Marvin \ Sound

The Canyon3D chip is SB Pro compatible and I assume it has some sort of FM synthesis emulation but there's pretty much no recorded samples or any information about how it sounds. Are there any recorded samples of this card's FM synthesis or can any owner describe it as something that's more like the …

RM750X (2017)? Fairly common right now second hand, I'd imagine. It's got 150w for 5v and 3.3v, it's fan only kicks in at 40% load (still pretty much silent), has rock solid voltages. I suggest this mostly because I had one and it was great. I only switched because I went SFX. No -5v but that's a …

Yup, either that or a heatsink with plastic clips that attact directly to the sides of the CPU. You can find a Z-clipped heatsink on Ebay still if you search for "Cooling Heat Sink CPU Pentium P75". They might collide with mobo parts sometimes but I've used them on socket 3 boards as well.

No problem! Another verified alive LAPC is always great since they're so rare 😀

Here's the differences on the back. 2.2v is smaller than 2.9v. I think I have all the different processes here. The P166s should be the same process as the lower voltage *L CPUs. The P150 is comparatively huge.

Glad I could assist, let's hope it's indeed just that and nothing severe. I don't think there's any harm in the -5v rail missing but I don't have any experience with LAPC-I (not for lack of trying though!) Voltage blasters can still be acquired on Ebay it seems which you probably noticed already. …

New PSU has a -5v rail? LAPC-I requires one.

https://i.imgur.com/RLP1toD.jpg So I did receive that 2.2v 300gp and it happily seems to work at 2.4v and 333mhz so here's some testing I did with a GF2 MX400 and a P5A 1.04. I didn't really tweak any settings yet or even install a soundcard so it's not really an "official submission" That's quite …

Will the pcmidi extensions be available separately or is it a package sorta deal? Is there a price yet for those? Also, great work on this once again, this is really awesome!

Have you tried formatting and reinstalling Windows 98 from scratch? Are you having this issue if you reboot into DOS and have you configured DOS? Phil has a great guide and tool for doing this: https://youtu.be/f52bZzWs-u4 What TX97-X board revision and BIOS version are you running? I also run a …

I’m using a 939Dual-VSTA as a test machine for PCI, AGP and PCIe cards. Until recently I was using a s939 Athlon 64 X2 4400+ dual booting XP and Win7 32bit with 4GB DDR2. I managed to find the AM2CPU future cpu upgrade board which I flashed with beta firmware to enable Windsor cpus. So now it’s …

I’ve had a great time working on my first Socket 7 build in over a decade. This project started with me struggling to get certain retro games working on Windows 10. Source Ports, hacks, ScummVM, and DOSBox allowed Windows 10 to meet and even exceed my needs for a long time, but I was re-organizing …

You'd better get this 366 rated v2.9, quite rare and interesting, if you ask me. The v2.9 is faster clock to clock compared to v2.2. Here's in case you're not joking (I can't tell): ...a little open secret. Chips over 333gp all run at 250mhz or higher and it's all about the FSB at that point. Cyrix …

Bah, I could get a post @ 112x2.5 on my SY-5EMA+ (so a 433gp I guess) easy enough but a Win98 OS drive I snagged off a different MVP3 board didn't want to play ball so I'll have to do a clean install just for this.

Oh here is a interesting find: https://www.ebay.com/itm/393974359571? I think this is using the 433gp core. 2.2v, small square cover on back,… Yeah, I just ordered one because I always wanted a 2.2v instead of the hot 2.9v. It's gonna be a few months so I'll have to bench the 333gp instead. Anyways …

Well, I am reorganizing and I do have a 333gp that I might be able to take to around 280mhz so hmm ... 🤔 I'm not familiar enough with 3Dmark. Will the CPU bottleneck with more powerful GPUs enough that the 3Dmark scores get normalized close to each other anyway?
