Re: [Asus P/I-P55T2P4 Rev 3.10] Help! MoBo with K6-III 450 restarts after bios all the time. Maybe poor power supply on

Posted on 2023-11-19, 19:56

"I have unplugged all cards and stuff except the graphics card and found out that the system boots when I have also unplugged my USB header with keyboard and mouse. (?)" Have you tried using a PS/2 mouse and keyboard? Assuming that you will be using Win9x, a PS/2 mouse is a good idea anyway since …

It seems you are trying to do two things at same time from your posts. Upgrade cachable ram and get a K6-III 450 working. you should focus on one first and then the other once the first is fixed, depending on the board/bios revision you may not be able to get both working perfectly at the same time …

Try removing and reinserting your RAM. If you have more than a pair of SIMMs installed, try it with just one pair installed, and if the problem persists, try the other pair instead. Maybe inspect the RAM contacts and the RAM slots for any corrosion? I have checked the RAM and have additionally …

Thanks for your replies! MoBo works fine and 100% stable with P133 and P200MMX. Both here on my table. Its mysterious. Just with the K6-III the MoBo has a problem. @Repo Man11 I'll check, but it's strange that the other CPUs are running fine. Any other ideas :( Can the power supply really be ruled …

[Asus P/I-P55T2P4 Rev 3.10] Help! MoBo with K6-III 450 restarts after bios all the time. Maybe poor power supply on 5V?

Hey folks, i got my AMD K6-III 450MHz today and of course installed it straight away. Unfortunately, the system keeps restarting after the BIOS almost every time I switch it on. Following settings are set: - BIOS: 0270-2 - Vcore: 2.2V and tested up to 2.5V with no change - Multi: 6 - FSB: 66MHz runs …

today i got my COASTt-Modul. Unfortunately it does not work with my P55T2P4. I updated my BIOS up to the latest official version but it did not change anything. What do you mean by "does not work"? If the system still boots fine but doesn't use 512KB cache instead of 256KB cache, make sure you …

Cache modules can be finicky, yet another reason to prefer later revisions of the board and/or using a K6-2/3+. I thought I got lucky with the cache module that I bought to use on my PCChips M520 because it initially worked when using a P55C, but when I tried to use it with a K6-3+ 450 it wouldn't …

Good evening folks, today i got my COASTt-Modul. Unfortunately it does not work with my P55T2P4. I updated my BIOS up to the latest official version but it did not change anything. Does anyone have any idea why the module is not working on the mainboard or has it working on the own mainboard? COASt- …

Re: [ASUS P55T2P4 Rev 3.1] Is the latest BIOS 207 in the VOGONS library the BETA 2 version and which CPUs are supported?

Posted on 2023-11-14, 07:28

That BIOS has been superseded by Jan Steunebrink's patched BIOS available on his page: http://www.steunebrink.info/k6plus.htm Many thanks. Does this mean that's the best choice for the K6-III? I am a bit confused. In WWW everybody talk about latest revision 0207-2 from 04/28/99 but on the ASUS page …

Hello folks, I am currently working on an ASUS P55T2P4 and would be very happy if I could get a K6 III 450Mhz to run on it. Various sources have recommended to use the BIOS V207 BETA 2. Unfortunately, every posted download link is offline. Does anyone know where I can get this bios version. On the …

Thats really interesting! In the manual to the ASUS P55T2P4 is written that up-to 512MB of cacheable RAM is only possible with Pipelined Burst Cache Module which means, no COAST module - no cacheable area bigger than 64MB. See attachment. That's not how I understand the attachment. The comment is …

To enable a cacheable area of 512MB RAM you _need_ to populate the 2nd TAG chip on the mainboard with a 16Kx8 12 or 15nS DIL chip and jumper everything correctly. This makes a lot of sense, because this chip will be used for 3 extra tag bits, multiplying the cacheable area by 2³ = 8. You also need …

Hello guys, first at all thanks for your replies and information. I guess i understand it and i am really interested in buying such COAST-module and TAG-SRAM chip to upgrading it with more then 64MB RAM. Combined with an 233MMX and Voodoo 2 it seems to by a nice build. Thanks and best regards. JF

Hello colleagues, First of all, I would like to say that I have really tried to read up. But I am still confused. Yesterday I got an offer for an "Asus P/I-P55T2P4 Rev 3.10" with SRAM chip socket and slot for a COAST module. I'm very interested in it, but I don't really understand the SRAM upgrade …

Re: [Gigabyte GA-586S] How do I get the maximum performance out of the motherboard?

Posted on 2023-10-30, 07:09

Hello CoffeeOne, thanks for the information. I must have overlooked that. Neither the system nor the chipset manual says anything about it. Somewhere I read that the cacheable area generally depends on the size of the cache. With 256KB cache the cacheable area is 64MB and with 512KB it doubles to …

Re: [Gigabyte GA-586S] How do I get the maximum performance out of the motherboard?

Posted on 2023-10-29, 23:27

I made a quick search and it seems that the cacheable area is 64MB. So doubling the RAM to 128MB will make it slower. Where do you get this information? In the manual of the mainboard is written it can handle up to 512MB. Don't know how to get this with only four slots :D Greetings JF I used Google …
