Ram

[Anti_Shock]

Recently my pc wouldnt boot up because one of the ram sticks was a different model compared to the other ones so i went down to 4gb of ram and recently i added a gpu to it and ever since i added it my pc wont load websites and it says website took to long to load please try again im maybe thinking i dont have enough ram cause a lot website says you at least need a minimum of 8gb of ram and i only have four is my ram a problem?

if my ram is a problem are these good ram sticks to replace in my system? https://www.amazon.com/Corsair-CMY16GX3M2A1600C9-Vengeance-Desktop-Memory/dp/B00D2LGRPG/ref=mp_s_a_1...

@Anti_Shock -- is this your computer: HP Pavilion p6722f Desktop PC Product Specifications | HP® Customer Support

It was first manufactured: 15-Dec-2010 -- quite "vintage".

That web-page states:

Memory upgrade information:

• Four DDR3 DIMM (240-pin) sockets
• Supports 1 GB, 2 GB, and 4 GB DDR3 DIMMs per socket
• PC3-10600 @ 1333 MHz -- DDR3-1333 modules run at 1066 MHz if three or more modules are installed.
• PC3-8500 @ 1066 MHz
• Supports up to 16 GB on 64-bit PCs (DDR3-1333 DIMMs will run at DDR3-1066)

So, in your case, 4 GB is barely enough. Adding another 4 GB is essential.

Maxing-out the 4 sockets will give you 16 GB of RAM.

Observe the special notes about the RAM running slightly more slowly when more than 2 sticks are used.

So in that case will the ram I linked up above will it be good for my system or do you recommend something else?

@Anti_Shock --  are these good ram sticks to replace in my system?

The web-page that you cite states:  Corsair Vengeance Pro Series 16GB (2x8GB) DDR3 1600 MHZ (PC3 12800) Desktop Memory 1.5V

while the web-page that I cited states a slower maximum speed for the RAM that is compatible with your motherboard.

So, the short answer is: not good. 

But, it is possible that the "slower" clock-speeds available with that RAM might be compatible with your motherboard.  Are you willing to risk it, and then have to return the purchase, if the sticks are not compatible?

Instead, see:  www.crucial.com and run the program on that web-site to identify  RAM that will be compatible. You don't have to purchase from CRUCIAL, but you will get the specifications that will work.

Alright then after a fair share amount of research i found this ram is this good? https://www.amazon.com/PC3-10600-DESKTOP-Modules-240-pin-Tech/dp/B00C537AWQ/ref=sr_1_1_sspa?dchild=1...

@Anti_Shock -- I went to that www.crucial.com web-site, and did a search, to find several compatible sticks:

Memory RAM & SSD Upgrades | hp - compaq | pavilion p6000 series | Pavilion p6722f | Crucial.com

Note that you need RAM with the "L" ("Low Voltage") specification.

Does this mean I can't get ram sticks that have 8gb because most of the ram sticks I see are 4gb and voltage shouldn't be a problem since I upgraded the psu

@Anti_Shock --  Does this mean I can't get ram sticks that have 8gb because most of the ram sticks I see are 4gb

Information on that CRUCIAL web-site indicate that your computer has 4 sockets, supporting a maximum of 16 GB, which is four 4 GB sticks. So, this means that 4 GB sticks will work. It does not mean that two 8 GB sticks will not work, but I doubt it.

> voltage shouldn't be a problem, since I upgraded the PSU

Not the same. A typical CPU consumes 65 to 90  Watts.

A high-end graphics adapter can consume over 400 Watts.

That's why you needed to upgrade the PSU.

But, the motherboard supplies only 1.35 Volts (not Amperes) to RAM branded as "L" -- low voltage, instead of the usual 1.5 Volts for "standard-voltage" RAM.  Using "standard-voltage" RAM will "under-power" that RAM, possibly causing the RAM to function incorrectly. 

Your research has found RAM that is priced at the same amount as the RAM from CRUCIAL.

Find a local computer-store that sells CRUCIAL RAM.
