I'm currently building a budget gaming PC and whenever I bought memory I was not paying too much attention and ended up buying Kingston HyperX 1866-ddr3 memory. It operates at 1.65V and my cpu is an Intel Pentium G3258 and it's recommended maximum is 1.575V. Should I lower the voltage on my memory or should I just ignore it?

You should be ok. Intel CPU's can work with memory up to 1.65v. Just be sure to go into your BIOS and find the setting for XMP, and turn that on so that your system will use the right settings to run the memory at the highest speeds.

I do hope you checked the motherboard memory compatibility list before you bought that memory though. Without the memory model number and motherboard model number, I could not check that.

As long as you keep the CPU properly cooled it won't make much of a difference. 1.5v is the recommended for 1155/1150 (I think, I might be off on that), but nearly all memory that's over 1600 is higher than that. The memory controller is on the chip, so your chip will get a little warmer but not to the point where you need elaborate cooling for it. It should be fine.

I don't have the model numbers but the motherboard is EVGA Z97 FTW. I don't think it is compatible! Thank you so much because I still have time to cancel!

If it is able to support up to 2666 MHz would that mean that it can run anything under it or does it have to specifically say so?

Ok, that is a Kingston 4GB kit on Amazon. No Kingston 4GB are listed as having been approved by EVGA for a EVGA Z97 FTW. The smallest Kingston kit approved was an 8GB kit.

Having said that, apparently pcpartpicker.com likes that memory as their logo is on the Amazon page.

I think I would go ahead and install it and see if things work out for you. I suspect they will. But, if you end up having weird little problems after putting your system together, remember this little conversation.
