Getting a decent PSU is now my top priority! :happy: Following on from the test set up above, I decided to alter the PSUs configuration before rerunning the tests. I did this: On the mobo, I removed 2 of the 3 chassis/CPU fans. I removed the HDD power cable from the "mobo PSU" I removed the DVD-ROM …

So far, so good. I've got the "aux" PSU providing power for just the nVidia 6800GT graphics card. Everything else is being powered by the other "primary" PSU. I ran 3DMark2001 first edition 4 times, and get these scores: 10025, 10132, 10131, 10146 (Consistent values) I max out all of the 3DMark2001 …

Thanks a lot, this works. I tried a simple set up to begin with: the "aux" PSU is simply providing power for the DVD-ROM drive. That's it. But it works, because I tested it in Windows 98. Now, I'm going to get the "aux" PSU to power a meaty graphics card. In fact, I'm going to try an nVidia 6800GT. …

Thanks a lot 5u3! :happy: I must just double-check something: I'm looking at my PSU power plug, and I can see that green wire. I'm looking at this green wire, as if it's on the "top row", as in your photo. Immediately to its left is a single black wire. Immediately underneath that single black wire, …
Re: Testing an Abit KT7A mobo
Posted on 2009-11-23, 13:54
I've just noticed something a bit unusual about an Abit KT7A non-raid rev 1.2 board. I'm testing a t-bred 2000+ rated CPU in it, and sometimes when I cold boot, the keyboard lights momentarily flash but I get no POST. The way to get around this, is to just press the Reset button on the mobo when you …

I've got a nutty idea! I can't afford a dedicated supplemental PSU ATM, but would this work instead: Get 2 "normal" PSUs, and plug them both in to 2 mobos. 1 PSU powers a "dummy" mobo which is not used for anything, the other PSU powers the mobo you are actually working on. The "dummy" mobo is …

I joked about a PC Chips fake cache mobo on this Vogons thread here - http://www.vogons.org/viewtopic.php?t=23065 This particular cache is not completely fake, as it isn't made of plastic! I think it's just normal RAM - no faster than SIMM RAM. If you enable the L2 "cache" in the mobo's BIOS …

Even though the mobile barton was only 1.35v, I couldn't get the FX5950 to work sensibly in the 1.2 board without problems. So I removed it, and replaced it with a t-bird 1200 (133fsb). It has a much greater core voltage of 1.75v, but I guess it uses less PSU power, as it's a much less powerful CPU? …

Now I'm using a mobile barton (1.35v, 2200+ rated, 1666mhz), instead of a t-bred (1.65v, 2000+ rated, 1666mhz), the FX5950 POSTs OK in the 1.2 board. I guess as the mobile barton is consuming less juice, there's more left over to get the FX5950 up and running?! I run 3DMark2001 f.e., but after a few …

I just tried a mobile barton in the 1.2 board. It's 2200+ rated. Looking at cpu-world, it has a core voltage of just 1.35v. The CPU code is AXMD2200FJQ4C. I took absolutely no chances, and popped out the mobo's button battery and also cleared the CMOS jumper! The BIOS POSTed first time. But to my …

I wanted to see why the FX5950 failed to POST in the 1.2 board, so I plugged this board back in again, and continued to use a t-bred 2000+ CPU with it. Rather than try the FX5950 once more (I see no point), I tried a Radeon 9800 Pro instead. And I get the same thing: no POST. But here's another …

I've swapped out the 1.3 board for a 1.2 board. The latest BIOS on this board is I think "A9" - (July 2002). It's older than the 1.3 board's BIOS, which is "B4" - (August 2002) Here's some "quick test" results - * Like the 1.3 board, this 1.2 also will not POST with a t-bred 2200+ (I must check if …

It's an interesting problem. It's only now that I realise and appreciate (from reading Prophase_j's postings) why the Intel Pentium 4 boards adopted that new 12v CPU dedicated power plug. I reckon they must have seen the problem coming by simply looking at the very last generation of old Athlon …

Hehe! Yes you're right regarding the "SET BLASTER=A220 IXX DX" line. I was just trying to be clever, and anticipated that as I hadn't run any setup procedure, I thought I'd convert those XXs in to meaningful numbers! I like the opening DF theme - those cornets or trumpets (or whatever they are …

Can you plug in a PSU on to a mobo in the regular way, but also use a second PSU to power just the graphics card? (I can have 1 PSU for the mobo+CPU+RAM, and another for just the AGP graphics card.) Also, can I buy a gadget that will tell me how much juice the PSU is consuming, on its 3 rails? That …

Dark Forces problem solved : Inside the sound setup utility, I selected Soundscape as the digital audio card. That detection process was successful. Then, the music card detection (for Soundscape) was successful. Strange. In other words, I had to set the digital audio first, then the music. As for …

I've got a couple of questions. :happy: 1) Can't get Dark Forces to play any music. 2) Can't get the IDE CD-ROM working/detected. 1) Dark Forces: inside its sound setup area, if I select "Soundscape synth" or General Midi (330) for the music, and then select the Test option, the cursor flickers …

Wow! I just got it working. :happy: I'm sure there was something amiss with my previous Ensoniq soundcard (a "Reveal clone"), because this one sounds very good! My current DOS set up is very limited ATM, and I've only had a chance to try Doom, but that opening track where you start sounds great. …

Following on from the post above - the only thing I've now done is swapped out the FX5950, and replaced it with an nVidia MX 440 (using the 45.something drivers). Everything else stays exactly the same. 4 lots of 3DMark2001 first edition testing = 3665, 4372, On the 3rd test, the benchmark utility …
