Could BSOD errors be caused by the PSU?

Most definately

what is Timing?

Example: Timing: 2.5-3-3-7

<{POST_SNAPBACK}>

Of the timings you listed (2.5-3-3-7) the 2.5 rating is for CAS, and I think I have the others after in the proper order, but Im not 100% certain.

Memory Timings (lower numbers are better):

CAS latency (CL)

RAS to CAS delay (tRCD)

RAS precharge (tRP)

Cycle time (tRAS)

what's this smokee

CAS latency (CL)

RAS to CAS delay (tRCD)

RAS precharge (tRP)

Cycle time (tRAS)?

hehe, and what do each mean? i tried googling em but couldnt find a clear definition for em.

The example timing numbers you posted 2.5-3-3-7 contain four numbers (the dashes are just separators) that correspond to the four descriptions I listed. The first number 2.5 is CAS (Im 100% sure of that). The first 3 is RAS to CAS delay, second 3 is RAS precharge (tRP), and the 7 is Cycle time. As I was saying, Im NOT 100% sure about the order of the last three. If I have it mixed up, hopefully someone will correct me.

As for definitions I dont know....except for these two things:

CAS = Column Address Strobe

RAS = Row Address Strobe

All you need to know about ´em is this, the lower number the better. The best timings you could have is 2-2-2-5.

This Crucial 512mb PC 2700 any good? because my ram that i have right now is PC 2700

I wouldn't recommend buying a RAM that's different in size as it could cause errors in some computer configurations. Always match ´em, 256+256, 512+512 and so on.

EDIT: If you're not OC'ing then you don't need to know much about timings.

With single channel memory, different memory sizes arent a problem. Dual channel memory is where that will cause problems.

so ok, lets say this, i run a 512mb in one slot, and a 256mb in another slot, in single channel mode, it shouldnt cause a problem right? but if i run those in dual channel, something will go wrong right? the dual channel part is not a problem for me cause my mobo doesnt support it anyways.

I didn't know that. Ok, then go ahead and buy a RAM. How much you got (or plan to have) to spend on the RAM?

right now i have 256mb, im going to buy a stick of 512mb for now and then later im going to take ou the 256mb and put in another 512mb stick. i want to spend around around $30-$50 on a 512mb ram.

these are some decent RAMs within the price range you wanted:

1.

2.

3.

Personally, if I would be forced to buy these kind of RAMs, I would go with nr 1.

then, number 1 it is , thanks everyone for all your help. ugg i guess i wont order until august since my mom keeps saying she will order all the parts for me later X_X.

Good Luck
