mattic Posted December 18, 2006 Share Posted December 18, 2006 I've just bought 2 x 1024 sticks of Corsair DDR2 Twin2X XMS2-6400C4PRO In my machine (P4 3.2Ghz, ASUS P5GD2 Premium Motherboard) I already have 2 x 512 sticks of Corsair DDR2 Twin2X XMS2-4300C3PRO When I put all the RAM in, I get an audible error that says, "System failure due to CPU overclocking" and the system fails to boot. If I remove the two 512 sticks, the system comes up with a visual error, "Overclocking Failed! Please enter set up to reconfigure your system." I also get the option to load default settings and continue, which I have done and everything seems to work fine. But, obviously with only 2Gig of RAM. The system is not overclocked in any way. How can I get all 3Gig working? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 19, 2006 Corsair Employees Share Posted December 19, 2006 I am sorry but that MB will not support 800 Mhz memory especially with a 533 FSB CPU. I would just stay with your 4300C3 modules for the time being! Link to comment Share on other sites More sharing options...
mattic Posted December 19, 2006 Author Share Posted December 19, 2006 Well, it's working with the two new sticks at the moment. System says 2GB RAM and it's faster. I just need to know how to make it 3Gb and why I'm getting an overclocking error when the system is bog standard. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 21, 2006 Corsair Employees Share Posted December 21, 2006 All of the modules would need to be exactly matched with most MB's these days sorry! Link to comment Share on other sites More sharing options...
mattic Posted December 21, 2006 Author Share Posted December 21, 2006 Righto, cheers. Given the fact that the new 2GB RAM is recognised and is working as expected (without the old 1GB), contrary to your advice above. Can I expect the whole thing to explode shortly? Or is it likely to be ok? Link to comment Share on other sites More sharing options...
dalems97 Posted December 21, 2006 Share Posted December 21, 2006 I think you have missed something: Your 800 Mhz capable RAM (currently installed) is being underutilized. If a Bios recognizes your memory, as yours has, and if that memory is faster than FSB of processor (533 vs. 800Mhz), then the bios simply runs the faster memory at the slower speed of your processor's FSB. The RAM Guy was 100% correct with everything he told you. But your system still should be stable, and enjoying the nice new memory! Especially with an ASUS board (Good choice). Cheers, dalems97 :D: Link to comment Share on other sites More sharing options...
mattic Posted December 21, 2006 Author Share Posted December 21, 2006 Thanks, mate. I really am a novice at this sort of thing. Wasn't trying to dis RAM Guy, just didn't understand. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 22, 2006 Corsair Employees Share Posted December 22, 2006 No worries I did not take it that way! Do you still have any questions? Link to comment Share on other sites More sharing options...
mattic Posted December 23, 2006 Author Share Posted December 23, 2006 Not really, I'll just run it this way until I buy a PC in the new year. I know it's an arse-about way of doing it, but what motherboard (ASUS) and CPU (Intel) would drive that RAM to its full potential? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 23, 2006 Corsair Employees Share Posted December 23, 2006 I cant really suggest one MB over another as it will cause a conflict of interest for me. But I would suggest looking in Dominator Qualifications and Testing! and start with the MB's we use for testing the modules. And the Core 2 Duo is the way to go for now; there is not really any reviews on the Quad core CPU's yet but they might hold promise, just check out the most popular review site I am sure they are soon to come out with them.

I have no conflicts. :) I would choose either the Gigabyte 965P-DS3, 965P-DQ6 or the ASUS P5B-E Deluxe motherboards. The Gigabytes have solid capacitors so that made my choice and they are great, stable boards. Link to comment Share on other sites More sharing options...
