Mobo and RAM

[Ari1127]

So I recently ordered the Soltek SL75DRV4 mobo. When i recieved it i noticed that it can only support pc-2100. Thing is i've already ordered ocz's pc-3000 ram from webuildpcs.com . I've read in other posts that this is still ok, and that i can just overclock the fsb to allow it to run at the 3000 mark. Is this true? In addition, i've already freaked out about spending $90 that i shouldn't have and tried to contact webuildpcs.com about cancelling my order. They have not responded to my emails for about 1 1/2 weeks. It's really aggervating. Is there anything i can do about that situation too? Thanks for your help.

That is the maximum speed that it can "Officially" handle. PC2100's official clock speed is 133MHz and PC3000 is 187.5MHz. The 3000 is the bandwidth numerically.

Hence,

133MHz x 2(Double Data Rate) x 8 bits/per cycle = 2,136,000 or 2.1Gb or stated as 2100.

187.5MHz x 2 x 8 = 3,000,000 or 3.0Gb or stated as 3000.

What you need is 1, to know is what does the board require and 2, find a memory that is as fast or faster to maximize the throughput for the processor.

SDRAM and DDRSDRAM are backwards compatible. This means that you can plug a PC3000 stick into a DIMM that is specified for PC2100 and it will still work. The same is true for SDRSDRAM. I have one machine, a Celeron 333 on a i440LX motherboard which originally had PC66. That was the fastest memory type in its day. I now have a stick of Samsung 256MB PC133 CL2 in it where it once had a stick of Non-Name 32MB PC66. It works just fine.

If you are going to overclock the memory than the PC3000 will give you a lot of headroom because it is designed to handle up to 187.5MHz "Officially" where PC2100 is only at 133.33MHz. That gives you headroom of 41%, which you will probably never need on that board. (Well I don't think that you could overclock it that high and keep it stable.)

I hope this settles your fears.
