Lol, Okay, I bought two sticks of 512MB DDR PC3200 (PC2100 Compatible) PNY Optima Memory, I put the two sticks in, after taking out my one 256MB stick. (I noticed that the PNY Sticks had an even amount of black chips on them, the 256MB stick had an odd number.) Okay, I shut the case, plugged it in, and I turned it on. no screen, and three long beeps.

I powered it down, and I opened it back up, took out one stick, and put in the original 256MB stick. It booted. Somewhat faster than before, I could tell. I looked at CPUZ and it was able to recognize the extra ram.

After that, I powered down again, opened, replaced the 256MB stick with the 512MB. It did that black screen and three long beeps.... OKAY, I'm mad now... Lol. I did switch the sticks (512MB) to check if it was one of them was broken or something... they were not. So after pulling out one of the new sticks and replacing it with the old one. I went into the BIOS, and I looked around at the Advanced Settings. I changed some of the SDRAM settings from "100MHz" to "Auto".



It still did the black screen with three beeps..........

Any help?

EDIT: Further inspections...

I took out the 256MB stick, and just left the 512MB Stick, and it looks like it won't turn on with out the PC2100.

I'm guessing that the new PC3200 Sticks will not work without the PC2100 stick to copy it's speed from, so in that case, I believe I must return the two sticks for 1GB of 2100-3200 and input that with the 256MB.

Am I right? or is there some other possibility?

I believe your problem is your motherboard only supports pc2100 ram. When you put the pc3200 stick in with it it clocks down to the pc2100 speed also. If you don't have your older stick of pc2100 in the sticks don't clock down and your motherboard can't support them. Hope this makes sense.

@Garmanma
It's a PC Chips M920.



@Sterling
Yes That is what I figured out... and I also bought this ram from Best Buy *sniffs*...

I might just have to trade my two 512MB sticks for one 1GB stick, and If I do that, I might want to find a PC2100 stick, for future thinking.

CAS Timing again pc2100 is 2.5. pc3200 is 3.0, dual channel 3200 is 2.5. this should work in your board. Not all boards time correctly with the incorrect speed in the board Crucial lists the best type of ram for your board as PC2700, and shows support for 2 gig max.

Well, I just returned the two 512MB sticks, and bought a 1GB PC3200 stick....

I see a little bit more of a difference, but I had hoped it would immensely speed up the computer.

But thanks for all your helpfulness guys.

Ya you'll notice things will load a few seconds sooner, but its mainly your processor doing the work ( I believe).
