Computer freezing after new RAM installation

[Jrudster]

Hello. I recently installed a 8gb stick of Ram into my pc adding to the 4gb stick i already had. Immediately after i booted my computer it froze on the desktop. Sometimes it can go hours, days, or even just minutes until it freezes. Here's what i have tried:

Using only the 4gb stick, using only the 8gb stick
Memtest to run through 6 times
Changing the timings

Here are my pc's specs
Mobo:Asus P8Z77-V LX
CPU:i3-3220
Gpu:EVGA 650 Ti sc
psu: corsair cx 500
Ram: 4gb- kingston hyperx blue 1600mhz ddr3
8gb-Pny ddr3 1600mhz

Thank you for any help.

This is what can happen when mixing DRAM, there's never a guarantee mixed DRAM will play together. Always best to get a full package of the amount of DRAM you want/need. If you can give us the model #s of the DRAM, we can try some voltage and/or timing adjustments to get them to play - no guarantees, but have had a lot of success in the past

Ok that makes sense the model #'s are as follows:
8GBH2X04E99927-15-H
KHX1600C9D3B1/4G

Try 1600 9-9-9-26, 1.6, 2T, and raise the VCCSA voltage + 0.06

I did as you suggested and my computer continued to freeze immediately after boot, unless there are any other fixes you can think of would it be a good idea to just get new ram?

Last thought, try 1333 at 9-9-9-24 1.5

I did what you said and my computer has not frozen for about a day now, however I will tell you if anything occurs.

Will be watching

Yep it froze this morning, now before i look into getting new ram, is there a possibility of any other hardware being harmed from this?

 

[Tradesman1]

Nothing should be harmed or damaged
