Problems with PC2700 memory, will interest anyone buying PC2700.

[blinky88]

A time ago I purchased on ebay 1GB of PC2700 memory from a company in the USA which turned out to be 512MB of PC3200, I assumed the seller must have labeled it PC2700. I didn't complain or go to the trouble of sending it back, I simply sold it for less than I paid as PC3200 and accepted the loss. All this time I believed the company in the USA had a shot at me, needless to say, I have never bought memory from the USA again.

My wife just purchased 1GB of Hynix PC2700 memory from Hong Kong which also turned out to be PC3200, this leads me to one conclusion, the supplier labeled it PC2700 in error and the seller unknowly sold it on as PC2700.

I bring this to everyones attention because new motherboards cater for Dual DDR as in my wifes case, so, if for example you have a new M/B with 1GB of genuine PC2700 and decided to take advantage of Dual DRR by adding an additional 1GB of PC2700 the chances are, it could be PC3200. If you have recently bought a Hynix PC2700 chip and installed it beside a genuine PC2700 chip, I suggest you do a bench test with the new chip installed and another bench test after removing it. You will find the PC is running much faster after removing it as PC2700 and 3200 clash. Some motherboards will accept PC2700 in 1 slot and PC3200 in another, the BIOS confirms the additional memory ..but.. it does not indicate whether or not chips are identical. By the way some M/B's will not boot with PC2700 and PC3200 installed, leaving you with problems that cannot be explained.

I hope this information helps some members who have experienced this problem.

ddr needs matched pairs of memory sticks to work properly. not just the same speed, but from the same maker, same timings, etc. it is usually sold in packs of 2 matched sticks.

This is only true if you want it to work as dual channel, otherwise it will all work at the lowest speed.

Even dual-channel mode will work with mis-matched sticks. But for best results, it is recommended to use matched pairs.

In the OPs case, regardless of how the sticks are labeled or what speeds they are, it is a matter of MB/BIOS support. It has nothing to do with memory from different manufacturers or different speeds. Just because a MB supports 2700 memory for instance, doesn't mean that it will function with ALL 2700 memory that is manufactured. The manufacturers website and the user manual typically have a list of all supported memory. If it's not on the list, then it isn't guaranteed to work.

Also, aside from just the speed, you also have single sided/double sided, parity/non-parity, low density/high density configurations.
