PCChips m598lmr

Post by mshail »

I have a PCChips m598lmr v5 motherboard with very few hours on it. It currently has a k6-2 550 running at 570. It also has 512mb of ram. I plan on using it as a Debian server (ssh, file, and proxy). I also own a K6-2+ 475 which this board should support but not without a bios update. I have already tried installing the processor but the system will not boot with the current bios. Should I risk ruining this board to upgrade the bios to use the K6-2+ processor or should I look for another socket 7 motherboard to drop it in and use the system for a light linux desktop distribution or even xp standard? Any suggestions would be greatly appreciated.

If you are going to flash the bios, I would first downclock the machine while running the K6-2 550 in it. To be really safe try about 500Mhz. Use the old processor for the flash. Make sure you are getting the right bios for the board, (That can be tricky, since some motherboard manufacturers, like Gigabyte, choose to provide 2 different versions of the bios with the SAME name, one from AWARD, and one from AMI; - if you use the wrong one your board is screwed.) Once you are sure you have the right bios, the next step is to make sure you have a good floppy disk. Format the disk and check for bad sectors etc before you copy the files onto it. Given a good floppy, and the right bios, things should go ok. One other detail, sometimes when you are flashing the bios, it will ask you if you want to save the old bios. I usually say NO, because if you say YES, then sometimes it asks questions to which you may not know the answers. THAT can be a problem because bios flashing is something you want to go smoothly with no screwups whatsoever.

Thanks for the tips to flash the bios. It went off without any problems. I have 1 question though. I am unable to run the new K6-2+475 at 2x(remapping to get a 6x multipler). The bios boots no problem but my operating system (Damn Small Linux) stops loading. I find this to be strange behavior because my regular K6-2 550 can do 2x without a problem enabling me to run at 570. Any suggestions?

P.S. I also just picked up a K6-III+ 450 that I am going to drop in this weekend.

I am not sure why you are having problems getting the 2x multiplier to remap as 6x. Never encountered that one before. This I will say however, -- You will get the best possible results by using the 5.5x multiplier with the fastest FSB speed you can run with it. 5.5x100 actually gives better memory read and write speed than 6x100. It is something to do with the way AMD optimized the processor. So for best possible results try to shoot for 5.5x112.

Thanks for the tip. I am currently running the processor at 5.5@97(2.0v) which gives me a speed of 522. I will try the 5.5@100 and see what happens. Do you suggest 2.0v or should I bump it up to 2.1v? I am running standard cooling and these boards are known for not having the best voltage regulators.

With a K6+ processor, raise it to 2.1v without hesitation. Higher than that, start being carefull. If I were you though, I would get a better than "Standard" heatsink fan combo. You don't have to get elaborate, just something like one of these :

I just installed the K6-III+450 in the system and I am able to get 570 (6x100) at 2.0v.

I have 2 questions. First, does the same 5.5 multiplier rule for best performance still stand for this processor? Second, who makes the heat sink/fan combinations you show and where can I get one? A specific brand and model would be greatly appreciated.

Yes, the 5.5 multiplier works best in my experience, see this thread for test results from 2 of my machines :

http://www.k6plus.com/index.php?name=PN ... pic&t=1434

If you have any doubts about it, you can check your own machine by running Everest on it using both the 5.5x multiplier and the 6x multiplier. You will find you get better memory performance with the 5.5.

As far as the heat sinks are concerned they are "Socket A" heatsinks which are interchangeable with socket 7 ones. The one with the closely spaced fins is an AMD, (it does give better cooling initially, though the closely spaced fins tend to collect dust which in time makes it worse), and the others are mostly Cooler Masters, though I don't know the exact model numbers because I got them second hand. If you want, I can send you one, because I have more of them than I'll ever need.

NOTE : If you carefully go through that thread I gave you a link to, you'll find this :

Having installed three 256 Meg sticks of Hynix HYM71V32635HCT8P-K, (PC133 CL2), in Superpuppy 2, I decided to see if I could get 112 MHz FSB stable.

Superpuppy 2 : ASUS P5A-B Rev 104 w/ K6-3+ 450 ACZ @ 5.5 x 112 MHz @ 2.3v. w/ mobo cache enabled. (First attempt; - has gone well, will try to reduce to 2.2v. later).

Everest :
Memory Read = 361 MB/s
Memory Write = 177 MB/s
Memory Latency = 182.8 ns

Sandra :
Performance Rating (Estimated) = 740
Arithmetic = 1521 D ALU MIPS ; 731 W FPU MFLOPS.
Multimedia = 3544 INT MMX ; 4217 FLOAT 3D NOW!
Memory Bandwidth : (Run repeatedly on account of rising results)
INT MMX : 210 ; 213 ; 229 ; 231 ; 238 ; 241 ; 240.
FLOAT FPU : 210 ; 216 ; 228 ; 234 ; 237 ; 237 ; 237.
Cache & Memory Bandwidth : 1164 - 2k ; 1179 - 4k ; 1183 - 8k ; 1164 - 16k ; 1120 - 32k ; 1036 - 64k ; 915 - 128k ; 630 - 256k ; 268 - 512k ; 236 - 1Meg ; 236 - 4Meg ; 235 - 16Meg ; 237 - 64 Meg ; 236 - 256Meg.

Rerunning Everest AFTER Sandra gave the following results :
Memory Read = 365 MB/s
Memory Write = 201 MB/s
Memory Latency = 184.3 ns

All tests run under WIN98-SE ; w/ Power Tweak 2's tweaks ; w/ : CAS Latency = 2T ; RAS to CAS Delay = 2T ; RAS Precharge = 2T ; RAS Active Time = 6T ; Row Cycle Time = 9T. - & my usual mess of 10 taskbar items running.
