I had a 'good' stick of 512 MB Samsung PC2700, that did 2-2-2-5-1 at 200-210 on a P4S533 board. However it could only muster 2800/2800 Sandra marks. I could clear 3k on the 1st mark only by cheating: disabling my USB ports, which are good for 200 marks on that board.
On an MSI 645E Max-LRU, the same stick could only do 154 FSB, 4:5 or 193 mhz max, at SPD-N-N-N. Around 2650 Sandra marks.
Also have 2 sticks of 256 MB Samsung PC2700, CTL sticks. These will do DDR412 and DDR426 (one stick) on a P4B266-E board. Breaks 3k easy.
Anyways, the 512 MB stick crapped out on me, so I RMAed it to Newegg and ordered another. Got the DTL stick. I decided to give it a try before returning it.
'Guess what folks? It performs exactly the same as the CTL stuff. Maxes out at the same level on the MSI board, and I got it to do DDR412 on the P4B266-E (see my attachment). Now I couldn't see if it will do 2-2-2-5-1 on the P4S533 board as I got rid of that board, but it maxes out at the level on the MSI board so looks like it. And the stick wasn't even burnt in.
As expected, it won't do DDR426 on the P4B266-E board as I could only do it with one 256 MB stick. But breaking the 3k barrier at DDR412 is not bad at all for 2.5-3-3-7 (which the board is locked out at over DDR333).
I think if you can't overclock the DTL sticks well, it must be a limitation of your motherboard.
