Ok, Upgraded my HP dx5150 cpu from AMD 3200 to AMD 4000, CPU works just fine. But Two of my four sticks of ram do not work anymore. The two that don't work 256 pc2100 and 256 pc2700. Upgraded bios to ver 1.19. Why do these two sticks not work anymore?

My operating system is Windows XP pro, And the two sticks that work are identical 256 pc3200. Before I could put the afore-mentioned(pc2100, pc2700) sticks in without a problem(with the athlon3200 cpu).
Now If I put them in(athlon4000 cpu), or even one in, Windows will not boot. The screen says a windows 32 file is corrupt(sorry dont remember the exact name of file).
Do they have to be identical? Maybe the athlon 4000 just works with identical sticks? Maybe the athlon 4000 just works with pc3200? That last question seems to sound most logical.

I can put "other" sticks in there, most recently: 2x 1gig gskull pc3200, 2x original HP 256 pc3200, and not have any problems. So maybe my older sticks were zapped. I still think its the new cpu, but not confident. Frying ram is easy to do:(

You do know that the pc2100 and p2700 runs at different speeds. You also have pc3200 ram stick which get clocked down to pc2100 speed which you don't get the full speed.

You are better off to put those 2 1GB G.Skill stick in as they are pc3200.

agreed, but those giga sticks are not mine(friends). Just wish i could use the older ones... which bring up the reason for this TOPIC. My pc will not recognize 256 pc2100 stick and 256pc2700 stick after cpu upgrade. Now that I think of it... After I put in my socket 939 cpu, I went into BIOS and "loaded optimized defaults" could this be the culprit? Doubtfull knowing that u can't even overclock HP pc's right?

Loading optimized defaults is pretty much standard procedure when making a major hard ware change. = processor.

You may be able to revert the BIOS settings to what worked before with the mixed memory. Or, by doing so you may run into trouble with the new processor.

If at all possible, upgrading the memory to matched sticks is the way to go.

So,
older sticks can slow a pc's ram down? I just did not think u had to match ram sticks. NEED MORE INPUT
Newegg is cool but ebay can have deals...

When RAM of mixed speeds is used then all RAM is automatically under clocked to match the speed of the slowest stick.
