Intel DG33TL MB memory selection

Your memory configurator http://www.corsair.com/configurator/product_results.aspx?id=294056

 

indicates that I should use the above memory for my Intel DG33TL MB, but the tech document from Intel sates that it should only use 1.8V memory with a 5-5-5 or 6-6-6 timing. This document states that this is a 2.1V module, and it has 4-4-4 timing. I would think that this voltage difference would not work with this board? Will the timing adjust to the slower numbers (set by the SPD from the MB), or will the MB just work the faster numbers? The optional over-clocker and extreme parts that are recommended use even higher voltages (up to 2.4V). I don’t see how this can work.

 

 

 

Is this module a better fit or a poorer fir (will it work)?

I think that you should hold off until the staff are back on Monday. There seems to be a problem with the Configurator as that DRAM is of a higher end than that board should be able to accept.

 

RAM GUY or another staff will be back Monday and will answer this issue then.

This motherboard is one of many Intel-brand motherboards which have no provision at all whatsoever to manually set the DIMM voltage. You might want to use a TWIN2X2048-6400C5DHX kit instead of the memory that you mentioned.

Is the configurator broken or at least inaccurate then?

Do most non-Intel MBs have programmable POL VRMs for the memory?

[RAM GUY]

The configurator is displaying incorrect modules for this board. We can only guarantee that Value Select modules would be compatible with this system since there is no way to adjust the memory voltage. The TWIN2X2048-6400C5DHX would likely function on the board, however we can only guarantee its functionality at 1.9 volts.

Most higher end motherboards have the ability to program voltages. Not on a Point of Load conversion or VRM, but they do respond to the VRD steppings when applied in the BIOS. Most of the older POL VRM modules have been changed to VRD stepping modules.

I just wanted to share that I run these modules (TWIN2X2048-6400C4) on my Intel DG33TL which only supports 1.8v @ 1.8v 5-5-5-18... I just can't go 4-4-4-12 due to the voltage restriction on the motherboard... However, the modules work great at these settings... :D:

OK thank you for letting us know, please let me know if you have any more questions!
