Please log in for more thread options each, exactly the same. Both sticks work in either slot. The bios recognizes it as 2gb of ram. I'm having trouble getting both sticks to post. One stick is 100% successful. I have to power off and on many times to get it to post with both sticks in. Custom PC. It runs great with two sticks. If I try and restart it with the two sticks I have the no post problem again. All the fans come on and the HDD spins for about 20 seconds and stops. Monitor is completely black. Never any beeps from the bios. System and processor are running cool. If I can't get it to work with the two sticks I will just use it with the one stick. My MB don't laugh to hard is a PC Chips M930LR. It has been good. Not many jumper options on the board that I know of other than clearing the cmos which I have done. The manual is horrible and says any jumpers you see on your board that you don't see in the manual are for testing purposes only. I can't see or adjust RAM voltages in my bios the way it is. Is this possibly a configuration problem I am having or something else? Some people suggest a PSU problem but I don't think it has a problem. It's 400W I have a Intel Pent4 2.6 processor. This does the job for me and fast enough as I'm not a gamer. It brings Photoshop up fast with 1gb of ram. Any tricks I can try? Thanks | |||||||||||||||||||

I've got an M920LR and it is very fickle. It took me awhile to find memory it was happy with. There was no pattern to what was acceptable, and what was not. Sorry I can't give you a better answer. The board sort of fell into my lap so I can avoid being hypocritical by saying: Don't ever buy a PCChips (PCChimps) board. Before I ever got the M920LR I knew they had a bad reputation, but the frustration I've endured since has made be a believer. > Not many jumper options on the board that I know of other than

My M920LR has a RAM voltage jumper, as well as a whole line of jumpers for selecting between DDR and "DIMM" memory, which presumably is DDR vs. SDR. Those jumpers were mentioned in my manual, which appears to only be marginally better than what you have for the M930. Any reasonably designed board should be able to sense which set of slots are populated and adjust accordingly, but we are talking about PC Chips here. > Some people suggest a PSU problem but I

The power supply is always suspect. The rating on the label is not part of the electrical composition of the supply, neither at the time it's new, nor when it's older and failing. It's good general advice, but you can reduce the load by stripping your system down to its minimum state. If your PC will fire up every time with two modules and just a hard drive (no optical drive, floppies, add-in cards, etc.) then I might wonder more about the power supply. (If you can eliminate your problem by going to a minimum state, just start adding bits back in until the problem reappears.) > Any tricks I can try? Thanks
I like the severed thumb bit, but have had to ply it upon random kids in the supermarket since my nieces and nephews have made it to junior high. http://youtube.com/watch?v=PbTIsLcnofw And, no, that's not me in the video. | |||||||||||||||||||

The SIS645 Northbridge is the one that interfaces to the RAM. The largest SDRAM I have here, is in the form of 512MB sticks. The largest DDR is 1GB. So my first question is whether it is SDRAM or not. I did find one example here, of a PC133 1GB stick, so I guess they do exist. This one is pretty ordinary looking, no tricks. Uses (16) 64Mx8 chips. They probably weren't making these in 2001/2002. http://www.valueram.com/datasheets/KVR133X64C3_1G.pdf The PCchips manual for the board, is on the ECS site now. It is an MSWord document. The board must be auto switching the voltage to the SDRAM or DDR, based on what it detects by scanning the SPD EEPROM. (Some dual RAM type boards used to use a jumper for that, but those boards probably killed more RAM than they worked with.) http://download.ecsusa.com/dlfilepcc/manual/m930/930s15.zip You could have a look in CPUZ (a windows program), and see how the actual memory running conditions, compare to the values stored in the SPD. Maybe you'll notice too aggressive a setting in there. http://www.cpuid.com/cpuz.php Paul | |||||||||||||||||||

I expect you have to make a choice as to what voltage to apply to VIO on the Northbridge. The Northbridge interface should run from the same voltage as the VIO on the memory. You could leave 3.3V on the SDRAM slot, 2.5V on the DDR, but make a decision as to what to apply to the Northbridge VIO. I have a board here, that has both SDRAM and DDR, and they used what look like QuickSwitches between the two pairs of slots. (They hid them, by putting an Asus brand name on the chips.) As transmission gates, that clips the signal level, and allows mixing two voltages. But you need a bit of spacing between the RAM slots, to put down the (ten) tiny chips. That sounds a bit too fancy for PCChips. I don't see enough room between the two pairs, for that here. This might be the M930LR here. http://www.clubedohardware.com.br/imageview.php?image=6350 This is the TUA266 for comparison, with chips between the two sets of RAM. http://www.multi-hardware.com/bdd/imgnews/TUA266.jpg What is also amazing about the M930, is that the benchmark results are so close for the two memory types. http://www.clubedohardware.com.br/artigos/639/5 Paul | |||||||||||||||||||
