I recently built 2 almost identical machines. only difference is one has an original Geforce 256 DDR 32mb ram and a USR 56k. modem one has an extra NIC. A friend is experiencing the same problems with the same case, processor, MoBo, Ram, Hard Drive. Another friend had zero problems with his AMD 1.4 and the K7s5a, same ram (different batch number I believe though) not sure of other components
Enlight Case with 340w Power supply ATX (AMD Recomended)
ECS K7s5a with lan/on-board sound
AMD 1.4GHz Athlon 266FSB Retail
256mb Crucial DDR Ram PC2100 (Crucial's part # CT3264Z265.16T and Micron # MT16VDDT3264-265A1 PC2100V-25330-B1 CL2.5)
MSI Geforce2 Pro 64mb DDR Video Card
Using On-Board Sound and NIC
Dlink 530TX additional network card.
Sony 52x CD-Rom
IBM 40GB ATA100 7200rpm Hard Drive
Both machines run stable under clocked to 1.05GHz with 266FSB (Though SiSoft Sandra says the bus speed is 200 regardless of bios settings of 100/133 FSB). Once I clock it up to normal 1.4 with 266FSB I get wierd seemingly memory related errors. (says a file is corrupt running 3dmark2001 though it runs fine in 1.05GHz. Other programs like Quake 3 for example will not load bots at 1.4 everything else plays fine it just wont load bots, at 1.05 it does everything fine. Though at 1.4GHz and 266FSB SiSoft Sandra recognizes the correct bus speed of 266. It does not recognize the ram maker though.
I am running the latest bios 01/09/20 I believe (Bios revision has removed Trendaway anti-virus). I installed the AGP driver using the .inf method (v.1.06)
According to the Bios temp monitor (SiSoft reads the same) @ 1.4GHz the cpu temp is around 40-42C under minimum load and reached 50C after an hour of Quake 3 (I got the bots to load one out of 10 tries @1.4GHz) with the system temp was near 28C at most times never seen it higher than that though.
When I go to Mainboard info in both, 1.05GHz and 1.4Ghz, the performance tips say...
Notice--SMBios/DMI information may be inaccurate
Warning--FSB exceeds chipset rated speed. Reduce FSB.
When attempting to install an OS while clocked at 1.4GHz was almost impossible. Cab read errors would slow installation from cd-rom and Hard drive, if it did finish the windows setup would come up with errors and FUBAR the OS. Tried WinME, Win981st, Win98SE all the same. Underclocked the thing to 1.05 and install of Win98SE went fine.
Anyone have any ideas to get this thing running at the recomended speeds? I have played with various bios settings but no luck. This mobo has been really bothersome. Though another friend had zero probs getting his up and running. Thats 3 out of 4 that are a pain or we are doing something wrong and dont know it. Just dont seem it likes anything @266FSB since @1.05GHz 266FSB SiSoft Sandra reads it as a 200FSB. Clocked to 1.4GHz 266FSB the machines flakes out.
Any help is much appreciated
Note MBM5 with K7s5a patch says I am only getting a core voltage of 1.71 Core 0 voltage. Shouldn't this be 1.75? My mainboard bios reads it at 1.744 to 1.760. This power supply is certafied by AMD...
