My PC is like this: 2,8Mhz Prescott Intel Pentium 4 on an ASUS MB P4R800V-DELUXE with a Kingston ValueRAM 512Mb DDR 3200/400 memory chip and an NVIDIA GeForce FX 5700 LE 256Mb graphics card.
I have this machine since March 2004.
About two weeks ago i bought a second Kingston ValueRAM 512MB DDR 3200/400 ram chip to upgrade my machine and use the dual channel capabilities of te Motherboard. I installed the second memory chip according to the manual, but about ten minutes later, while working, a blue screen came up and the PC, after emptying the memory to the HD, restarted. This went on for about 3 or 4 times.
I then quit and tried to start the machine only on the new chip. The blue screen came up just before logging in in Windows. Three times. I then reinserted the old memory chip and everything worked fine.
I took the new memory chip to the store i bought it and they gave me a new one, exact same maker and model. I retried with both chips and the blue screens just continued coming up while working in windows.
I retried also to restart only with the new chip and i also got blue screens before logging in in Windows.
I then checked the manual again. It says that when using DDR 3200/400 i can get up to 2GB of memory using dual channel installation, with only one chip per channel (while on DDR266 and 333 you can get up to 4GB on all 4 slots). I then checked the updated manual of the Motherboard in the ASUS site and it stated the same, also reporting that Kingston chips will work fine on the MoBo and are recommended. I went on and searched on Kingston's and ValueRAM's site, and here comes the funny story. Kingston says that my motherboard will only support 512MB DDR3200/400 (in total) ram on dual channel (one chip per channel), while with DDR266 and 333 it will indeed support 4GB ram on all slots!
Well, i mentioned that to ASUS support and they asked me to download the latest BIOS and try again. I did that, but when i again tried to start the PC only with the new memory chip, it gives me blue screens, but now they come up even sooner, while the Windows XP loading logo is on. And of course, i reinstalled just the old memory chip and everything is working fine. I posted again to ASUS support, but i must say that i do not expect much from there.
Well, what do you say? Any suggestions?
I am anxious, because i do not know how to upgrade my machine and don't know what to do with the new chip i bought for 52,90 euros. It definetely doesn't work with my MoBo. And time passes by and i need to know what i could do in order to get my upgrade and not lose my money. The guys from the store stated that they would change the memory chip once more, but i believe i should better ask for my money back as it seems that there is a serious compatibility issue between the chip and the MoBo. What do you say?
And a last thing. Do you think i could search for a memory chip manufactured about the same time my first DDR chip was? Would that make any difference?
That's my story. Waiting for some kind of advice or solution.
Thanks in advance.
PS: Could it be a Windows XP issue? Here is the last message i got on the blue screen, with only the new memory chip onboard.
