OEM mobo with amd-751 and VIA VT82C686A chipsets .. will a l

Hello,

I am new to these forums, so I apologize if this information has been covered previously. I searched the forums and google for info, but I came up blank.

Basically, I'm considering purchasing a luna ii pci card for my pc, but I'd like to be sure it will run reasonably well on my system.

Here are the specs:
OEM machine (hp pavilion 9780c)
900MHz AMD Athlon
128MB pc100 SDRAM (soon to be 512MB pc100 sdram)
60 Gig IDE Hard drives (2)
NVIDIA RivaTNT2 graphics card
soundblaster pci128 sound card (will be used only for midi and game audio playback)
hauppauge wintv pci card
WinXP

I am at a loss as to determining my motherboard manufacturer and make but I stumbled across this page: http://www.hp.com/cposupport/personal_c ... ml#P33_956, which lists motherboard info relevant to my machine.

Now, this page says I have the NorthBridge chipset as the AMD-751 (irongate), which is what HP had listed on the product website for the overall chipset. However, it also lists the VIA VT82C686A PCIset for the SouthBridge chipset. I've been browsing this board for a bit now, and it seems I should stay away from VIA chipsets, but since this is not the kt133a, would it affect luna ii performance at all? Or is there a tool to determine which exact chipsets my system is running?

If everything is OK, I am really looking forward to getting the card, so I appreciate all responses

Thanks,
Mike

Ive used this chipset with Pulsar - it works fine but you are limited with loading reverbs and loads of asio channels.

Thanks for the prompt response. Is the issue you're referring to the same as <a href="http://www.planetz.com/forums/viewtopic ... um=5">this one</a>? I would be buying the card mainly for routing and to offload some DSP processing from the CPU, and I wouldn't be using the scope synths/samplers. So, since this is the case, would it be a bad purchase and would I be better off with another mobo & cpu?

Thanks,
Mike

fyi, even the biggest synths almost consume nothing in the pci bandwidth. Samplers, delays, reverbs does thou.

Hrmm, I guess I should have been more clear.. I meant to say, the reverb/delay stuff is one of the reasons i'd be getting the card, and the synths aren't as important to me right now. So, I'm more concerned about whether or not my mobo is able to handle the reverbs and stuff. Maybe in that context my question makes more sense.

Oki, here comes the bummer: I could not load ANY reverb on my MSI 694D pro, a dual P3 VIA deck. Not even with the tweaks.

You might buy the card if you want to
1) try tweaking your mobo or
2) change mobo later if no tweaking helps.

What's the cost of a mobo compared to your DSP environment? I got an 815 chipset and I can load 8-10 reverbs.
