Pentium-MMX Board with fast DMA?

According to ASUS it should work with the TVP4, but I'm not sure how well. You're likely find it difficult to find a VX board that gives stellar DMA performance, as it's an inferior chipset whose only real benefit is the ability to use SDRAM. BTW, my ABIT IT5V gets a DMA score of about 40 or so. It's not great, but with a fast CPU it really doesn't hold me back too much. I'll just have to make due with it until the TX boards are released. -- The IWCCCARS Project: Q & A Representative [link lost in import] [link lost in import: /~ebusch/]

Well I have the Supermicro p5ste board running 200mmx, 64meg ram, Matrox Millinium, and it flies. I can turn all textures on in GP2 and i get the maximum frame rate. I'm very pleased. Check out www.megacom.com for info on the board. Chris

Perhaps he'll appreciate this info, but it's irrelevant. If you read his post you'd see that he was looking specifically for a VX board. He is using SDRAM and an HX board (like the P5STE) will be of no use to him. Secondly, he wanted to know about DMA speeds with regards to the Rendition based accelerators. You're using a Matrox card, so again your input doesn't pertain to him. I know you're trying to help, but try to pay a little attention to what is being asked. -- The IWCCCARS Project: Q & A Representative http://www.theuspits.com/iwcccars/index.html http://userwww.service.emory.edu/~ebusch/

Hi everybody, I just tried to build me a very fast computer around my Rendition card. Got a 200-MMX, 32MB S-DRAM DIMM and an IWILL TV-55 motherboard. But big surprise! The board doesn t support DMA access for the Rendition card. Also FIFO is worse than on my old T1-board. Does anybody of you experience a board with good DMA access with the Intel-VX chipset and MMX-support? Does DMA access work with the ASUS P55 TVP4? I d really like to race Indycar2, Nascar2 .AND. GP2 with good framrates and the phantastic textures on. Thanks for your help! Klaus Hoerbrand

What do you think of this board? I'm thinking of buying this very board. What did you pay? ECS has the 512k version for $160.

Thanks for your help. I finally sold the IWILL 55TV and bought me an ASUS P55T2P4. The setup for all kinds of CPUs (including MMX, excluding Cyrix 200) is unproblematic. I get a DMA score of 120 with the Pentium 200MMX. Indycar-, Nascar2- Rendition versions fly. Even GP2 runs on all tracks except Monaco with CPU-occupancy smaller 100% with nearly all textures on.

This is BAD. can't be this bad I have a Tyan S1470-VX motherboard with 512k Pipeline burst cache 16 megs of edo ram p200-MMX processor Intergraph Reactor 3D Card My DMA test scores are 33.1 MB/sec This sounds waaaayyyy to low. any help??

Unfortunately there is not much you can do with the VX chipset. Since you're using EDO, there is absolutely no reason to have a VX board anyway. Switch to SDRAM or get an HX board. While your DMA scores will be unaffected by the addition of SDRAM, the entire system will run much better. -- The IWCCCARS Project: Q & A Representative http://www.theuspits.com/iwcccars/index.html http://userwww.service.emory.edu/~ebusch/

Unfortunately, the newer Tyan MBs have "terrible" DMA scores. Anything over 40 should be "ok", I didn't see any VQUAKE framerate increases when tweaking my Titan III from 67 MB/sec to 112 MB/sec (with AMI BIOS). I did see a 5 FPS increase when going from 11 MB/sec (MR BIOS) to 67 MB/sec (back to Award BIOS). ------------------------------------------------------------------------------------------ This space intentionally left blank

Is it possible to switch between different types of BIOS? I have Award right now, and there is no option in my BIOS for Pci latency. Wasnt Tyan supposed to meet about the rendition problem?

Yes, but I haven't heard anything from rendition on any NGs about the results. ------------------------------------------------------------------------------------------ This space intentionally left blank

Please visit the Tyan website <http://www.tyan.com> and leave a message for the Tech support "asking/demanding" that they give us a PCI latency timer switch in the Award BIOS. Please send the e-mail to the Tech support not the webmaster. Regarding flashing an AMI over the Award: It can be done, I have heard others doing this. Tyan does not recommend it. Or you can buy an AMI BIOS for your Tyan board (contact your vendor). -- **************************** Michael E.
