That is one of the strangest things I have heard, infineon is very good and all but I never thought Crucial would send it out, since it is made by seimen(sp). It cost more, and for a long time was considered the best. But it should work fine.

Is this a 512MB DIMM? I remember seeing in another thread that Crucial was using Infineon chips on their 512MB DIMMs.

kevman,

No, they're not as good, but they're close...just a few MHz difference in their max attainable.

From my personal experience Infineon chips are the best to overclock. I personally get most of my memory from CompUSA (their brand) which is made by PNY with Infineon chips. I can easily get the FSB to 150MHz while still at CAS2. The last memory I bought was a 256mb stick which was $25 after MIR. What a deal!

I just wanted to let you know that I have a 512 meg chip from crucial (pc2100) with infineon chips and it runs perfectly stable at 150Mhz 2-2-2

I think Crucial puts Infineon chips on all 512 MB DDR sticks... That's what I have on mine. They run perfectly stable at FSB 150 CAS2 but I have to turn down the settings from "Ultra" to "Normal"

Thanks all, I think I should be good then. I'm bought a 512 Stick from them and I hope to oc with it.

Hmmm......I just ran into a similar situation today. Received my 512 stick of DDR from Crucial and it has Samsung chips on it. I thought Crucial claimed on their website that one of the reasons their RAM is superior is because they manufacture it and control the quality themselves. What gives? I'm a little disappointed...this was going to be partnered up with a 1.8a northy and a P4B266....hope the Samsung chips are up to the task.

Don't want to be the bearer of bad news, but Samsung chips are not supposed to be the greatest overclockers on DDR modules. Good quality and all, just not for running too far outside of specs.

Here is an email I got from Shelley at Crucial when I emailed them awhile back about this question.

Hi Mark,

"Currently, the 512MB DDR modules we sell contain either Micron or Infineon
chips. Although we are a division of Micron, we do occasionally sell
products manufactured by other companies to meet the diverse needs of our
many different customers. At Crucial, it's our goal to bring customers the
high-quality memory products they both want and need. We've received
countless requests for 512MB PC2100 DDR, and because there has been higher
than anticipated demand from Crucial's customers, Micron cannot supply the
needed volume to fulfill all the requirements at this time. As with all
our memory, Crucial 512MB PC2100 DDR is fully-tested and qualified to meet
the most stringent requirements of the world's largest computer
manufacturers. And all Crucial DDR comes with the same lifetime warranty and
expert customer support you've come to expect when you buy memory from us.

Let me know if you have any more questions!

Thanks,
Shelley"

"Other companies" would include Samsung. I have a stick of 512 MB DDR RAM from Crucial that has Samsung chips and can run them at a 155 FSB with the memory settings at 2.5-2-2-2-5 (or however many 2's there are) with a Turbo 2 setting on a P4B266. Anyone know what the limit on the memory really is? I've run my computer at 160 for half and hour to an hour before getting a blue screen, but from what someone described, the problem is the CPU because they fixed the blue screening by increasing their CPU voltage.

hmm where can i check what speed my ram is? All i can see is MT...does that stand for micron technologies?

I've been playing with my new P4 1.8A/P4B266 and am using my Crucial 512Mb sticks with the Infineon chips.

I can get 115FSB (305Mhz @ 3:4 divider) to run fine (Prime95 for 15hrs, no errors). I can't get 125 FSB (333Mhz @ 3:4 divider) to boot into Windows.

Just bought 2 x 256 sticks of Kingmax PC2700 (DDR333) to play with.

I'm hooked on the idea of being able to run my RAM at 333Mhz. The 305Mhz Sandra scores are real good already (2317MB/sec vs. 2070MB/sec at 266Mhz. PC800 RDRAM is 2450MB/sec)


Edit: BTW - if I set it to 125 FSB and 1:1 divider (250Mhz) it boots fine and runs Prime95 fine, so it is the RAM speed that's the issue here. I use "Turbo 1" to fix my PCI/AGP bus speeds.
