Problems with additional RAM aand NIC
X posted. 2nd attempt as the first time I left the header off and it hasn't
appeared! I recently purchased additional RAM for my system. The existing was 2x256k and for the remaining slot I bought 512k.(All the same spec/supplier/manufacturer). The system has been stable for some time so I added the vcache 512000 entry into the system.ini and let that run with no problems for a couple of days. I then added the 512k RAM which the Award BIOS recognised and dealt with. Unfortunately, I then realised that there was no Internet access. The 2091 router saw the PC power up but no data sent to line. Checks on the system revealed a problem with the VIA Rhine II fast Ethernet adapter. Now try as I might with reloads of software from the ASUS and Windows CDs, I couldn't get the NIC to be accepted by Windows. Even turning the LAN off and on in the BIOS was recognised by Windows but did not resolve the problem. Finally I powered off, removed the additional RAM (no difference) and then restored a previous version of the Registry and hey presto all OK. Question was I just unlucky or is there a tie in between the additional RAM and the Rhine adapter? Alan |

Alan I cannot think of a reason the NIC would fail when adding memory ...but then again NIC drivers do get corrupted ... reboot into safe mode and remove all entries relating to your NIC (and any other NIC cards found there) ..you may have a ghost NIC in there...(control paneldevice manager reboot and let windows go through the install of the drivers again .. post back : |

Some time ago I did clear out ghosts but I will check again. In the meantime, I also took the liberty of e-mailing ASUS and spent time surfing to see if there is anything the MOBO can or cannot do. One of ASUS posts for the A7V8X-X suggested there may be a problem depending on the speed of the FSB. I am using an AMD Athlon XP 2200+ and the BIOS is set to auto for this and I am having difficulty finding what speed it is running at in terms of FSB. The spec. for the MOBO for the Memory says 3 x DDR DIMM Sockets, Max 3 GB unbuffered PC2100/1600 non-ECC DDR SDRAM. A note then says:- PC3200 maximum to 2 banks only. PC2700 maximum to 4 banks only. I am using PC2700 so am limited to 4 banks - but does anybody know what the deffinition of a bank is? In addition the CPU socket spec. says that when using 333MHz FSB CPU, system memory supports DDR333 only. I don't understand this, can anybody explain the significance. Thanks Alan |

FSB of the processor has to match the FSB speed of the motherboard/memory or they do not communicate properly (Front Side Bus) |

I don't appear to have a pause option during POST but do confirm the correct speed of 1800 is being given. At present System Info giving an IRQ of 3 for the Rhine LAN. I have been spending time checking over everything - just to make sure. I found this little gem buried deep down in the ASUS web page for the MOBO and it wasn't there a little while ago when I last checked. Anyway what it says is concerning the memory banks and according to ASUS, one single sided DIMM means one bank, one double sided DIMM means two banks, two single sided DIMMs means two banks etc. Banks doesn't mean slots in their logic! So in my case there are three slots on the MOBO and using PC2700 I can use 4 banks, i.e. 2 doubles or as I have one double and two singles. Why they don't put this in the user's manual is beyond me. I have had all the RAM out and checked it against the Samsung DDR SDRAM Module Code Information and as I thought, it is all the same type. When I was running the 2 x 256 modules I also logged onto www.crucial.com/uk to check what they said and use their little routine to analyse the memory options for my MOBO. Very useful and confirmed what I had done was correct with the same option for upgrading to 1 Meg. Next step was to put the 512 into slot one and nothing else and see how it runs. At present all OK and no failing devices! I shall then upgrade the system.ini again and try one 256 at a time and see what happens. Alan |

Question was I just unlucky or is there a tie in between the additional RAM and the Rhine adapter? Alan I cannot think of a reason the NIC would fail when adding memory ...but then again NIC drivers do get corrupted ... reboot into safe mode and remove all entries relating to your NIC (and any other NIC cards found there) ..you may have a ghost NIC in there...(control paneldevice manager reboot and let windows go through the install of the drivers again .. post back : I note your comments. Some time ago I did clear out ghosts but I will check again. In the meantime, I also took the liberty of e-mailing ASUS and spent time surfing to see if there is anything the MOBO can or cannot do. One of ASUS posts for the A7V8X-X suggested there may be a problem depending on the speed of the FSB. I am using an AMD Athlon XP 2200+ and the BIOS is set to auto for this and I am having difficulty finding what speed it is running at in terms of FSB. The spec. for the MOBO for the Memory says 3 x DDR DIMM Sockets, Max 3 GB unbuffered PC2100/1600 non-ECC DDR SDRAM. A note then says:- PC3200 maximum to 2 banks only. PC2700 maximum to 4 banks only. I am using PC2700 so am limited to 4 banks - but does anybody know what the deffinition of a bank is? In addition the CPU socket spec. says that when using 333MHz FSB CPU, system memory supports DDR333 only. I don't understand this, can anybody explain the significance. Thanks Alan a "Bank" is the slot the memory goes into (what you are using sounds ok ...did you try just the 512mb ?) FSB of the processor has to match the FSB speed of the motherboard/memory or they do not communicate properly (Front Side Bus) I can't seem to find what FSB speed the processor is running at. When I check in the BIOS nothing appears to relate to it and the settings are auto. The BIOS correctly identifies the AMD OK at POST but no FSB detail. Alan if hit "pause" quick enough at boot time , you should see the CPU speed and stepping.(and IIRC you can see it in sysinfo under accessories/tools ..going from memory here :) most motherboards will detect and automatically adjust bus speed to match the CPU and Memory Thanks for your input. I don't appear to have a pause option during POST but do confirm the correct speed of 1800 is being given. At present System Info giving an IRQ of 3 for the Rhine LAN. I have been spending time checking over everything - just to make sure. I found this little gem buried deep down in the ASUS web page for the MOBO and it wasn't there a little while ago when I last checked. Anyway what it says is concerning the memory banks and according to ASUS, one single sided DIMM means one bank, one double sided DIMM means two banks, two single sided DIMMs means two banks etc. Banks doesn't mean slots in their logic! So in my case there are three slots on the MOBO and using PC2700 I can use 4 banks, i.e. 2 doubles or as I have one double and two singles. Why they don't put this in the user's manual is beyond me. I have had all the RAM out and checked it against the Samsung DDR SDRAM Module Code Information and as I thought, it is all the same type. When I was running the 2 x 256 modules I also logged onto www.crucial.com/uk to check what they said and use their little routine to analyse the memory options for my MOBO. Very useful and confirmed what I had done was correct with the same option for upgrading to 1 Meg. Next step was to put the 512 into slot one and nothing else and see how it runs. At present all OK and no failing devices! I shall then upgrade the system.ini again and try one 256 at a time and see what happens. Alan Now running 768 with no apparent problems. Alan good to hear : Just tried the last of the RAM (256) to bring it up to 1Meg and again the Device Manager reported problems with the Rhine adapter under NDIS and of course no access to the internet via the onboard LAN interface. It said it was either faulty or bad/incorrect drivers. It Control Panel/Network the Rhine adapter properties didn't change. This time I didn't try reloading any drivers but just powered down and removed the 256 RAM stick and powered up again and all OK with 768. FYI whether 768 or 1Meg the POST says the RAM is OK. Any clues? Alan |
