Prize K6-2+ brings life to P5A-B

Post by mulvihill »

I picked up my K6-2+ from k6plus on Friday and harnessed it to a P5A-B which had been limping along with a K6-2/400. All it needs now is a decent vid card. The old 8MB PCI Rage Pro is not quite making it. It has a lot of nice features like TV-out but it is bootlenecking the system now. That Voodoo 5500 from Tweakmonster would have looked good in there. <br>Before installing the 2+, I swapped out the old AT for an ATX PSU. It fired right up like nothing had happened. It didn't even need a BIOS tweak but I flashed it anyway to the 1011.005.<br>I set the voltage to 2.1<br>FSB to 105<br>multiplier to 5x<br>Explorer took "exception" to this so I checked the temps and found the CPU at 70 degrees C. When I set it back down to 2.0 the temps dropped to 43 C. and everything was cool (so to speak). <br>Anyway, it is as happy as a clam at these settings and so am I, but you have to wonder - how could 0.1v. make that much difference? <br> <p></p><i></i>

I don't think it could make that much difference. Are you absolutely sure that the jumpers were set to 2.1?<br><br>A K6-2+ running at 525 is abnormally warm at 43C. When I run my III+ at 618 at full load, it only gets to 36C ($6 Coolermaster HSF). Maybe the ASUS board reads hotter by nature though. <p> Epox MVP3G5, K6-3+450@618, 256MB SDRAM, CL GF2 GTS, IBM 60GXP 20GB, Fortissimo II Sound<BR><br>ASUS TX97-XE, K6-3+450@500, 256MB SDRAM, Voodoo4 4500 PCI, WD 40GB, SB AWE64 Sound <BR><br>ASUS A7N8X Dlx, Athlon XP 2400+, 512 Crucial DDR, Radeon 8500, WD 80GB SE, onboard sound/LAN</p><i></i>

How do you read the temps?<br><br>I remember that my P5A gave way different temps<br>depending on which bios rev it was using, probably<br>due to the thermistor offset compensation (should<br>only be applicable if you're using MBM or similar software) <p>------------------------------[ my rig ]------------------------------<br>K6-3+ 450@577 (115 x 5), Gigabyte GA-5AX rev5.2<br>386 MB generic RAM<br>15 GB Quantum Fireball LCT + 60 GB Seagate Barracuda IV<br>Radeon 8500LE @ 294/326 MHz (core/mem)<br>SB Live!

heat

Post by mulvihill »

I am reading temps from the BIOS, but I did take the first temp from the 1007 Bios and the second from the 1011.005 version. I wouldn't have thought it could make that much difference.<br>The other thing is, the heatsink has one of those pads on it. The pad is about 1.5mm (1/16") thick or more and has a few wrinkles in it so I honed it down a bit and added a bit of Radio Shack heatsink compound. I'm not sure of the make of the heatsink. It has a Coolermaster fan on it but I sometimes just swap a fan when it gets too loud rather than R&Ring the whole thing. I have a hard time believing that a soft substance like that could conduct heat efficiently but I thought it may help by conforming somewhat to the irregular surface of th K6-2+ cap. <p></p><i></i>

another P5A-B owner! here's some random info...

...in case you don't already know any of this...<br> I've been running a k6-2+ 450 at 518 (115*4.5) for about 9months now w/ win98se, 256mb pc133 cl2, & a radeon 8500. A few things to note; I couldn't run any fsb higher than 100 w/ the onboard L2 enabled. Seemed to run faster w/o the onboard L2 (or L3 as it became) anyway. That latest beta bios not only correctly id's the cpu and speed, but also correctly enabled write allocation; did not before. The cacheable limit w/ the k6-2+ is 512mb; vs. 128mb with a non-on-die-l2 chip.<br> On the note of voltages, I'd always recommend starting at the minimum and working up, cuz a lot of cpu's will not great (and cool) at a lower V. I just sold my old comp w/ a k6-2 450 2.4v core that I run at 1.9V (Asus TX97XE). And I've run a P233mmx 2.8vcore at 2.4v. Anyway, I've done lots of testing on this board if you have any ?'s. <br> I have had major problems running my radeon w/ any drivers newer than Catalyst2.2 though. I've tested -everything- except for removing the Promise Ultra100 controller, and disabling AGP sidebanding. I'm going to be getting another p5a-b system today to build for my sis and am going to test it barebones style; w/ win98se and winXP.<br> Finally, I use Asus Probe 1.12.? or something (newer versions wouldn't work) at ftp.asus.com.tw. Ali AGP drv 1.90, IDE drv 3.56, ide cache and mode utilities, agp control panel 1.40; all available at aliusa.com. The agp control panel can control frame buffering, agp bus, sidebanding, write allocation, write combining, GAT modes, lots of stuff. I'm still in the midst of testing that stuff.<br> <p></p><i></i>
