Will the two sticks of RAM be compatible?

Question

Iron

I have an Asus P5Q motherboard with a DDR2-800 M3 78T5663EH3-CF7 RAM module. Will they be compatible with DDR2 800MHz memory modules from other vendors (in Dual Channel mode)?
Thank you in advance if you advise inexpensive options for compatible 2GB sticks.

Answer 1

On my p5ql-e, 2 bars, 667 and 800 from different manufacturers, work fine in dual-channel mode. But at a frequency of 667.

Answer 2

If the timings are identical at the corresponding minimum frequency, then they should start, but still need to be checked.

Answer 3

If the strips are of the same frequency, they will work. The last time I saw problems was in 2004 on the Socket A platform. Modern chipsets allow you to set different settings for different channels, which is what the BIOS uses with success. But with 4 slats, problems are already possible.

Answer 4

Frequency is not everything, timings still affect.
But they generally do not advise using different strips if you want two-channel
