If it weren't for the white securing clips and previous matched pair of 512MB memory I might not have known what was the "Channel A" memory slots. So I moved the preexisting matched pair of 512MB (PC2-4300 533MHz) memory from the "Channel A" slots to the "Channel B" slots and installed the matched pair of 1GB (PC2-5300 667MHz) PNY's into the "Channel A" slots. Once I started the computer, I instantly wanted to make sure the computer recognized the memory and went into the BIOS. I did this since I moved the preexisting memory AND I installed new memory with a higher clock speed capability (667MHz versus 533MHz). I had to trust that the PNY would work, but I had to verify the motherboard would work with them also. Thankfully the motherboard recognized all the memory and did not show any conflicts. And I resumed the boot in to Windows and no issues there either; it went straight to the Windows login screen.When I opened the Dell E521 (AMD Processor), I saw that the "Channel A" memory slots were actually next to each other as I expected with the previous matched pair of 512MB (PC2-5300 667MHz) memory. As before, I moved the preexisting matched pair of 512MB memory from "Channel A" to "Channel B" and installed the PNY's into "Channel A." Again, I instantly went into the BIOS to make sure the computer recognized the memory. The computer did recognize the memory and so I resumed the boot in to Windows. However, this time on the Dell E521 it didn't get to the Windows login screen. And after about 30-minutes of moving the memory around I figured I needed to see if I could even get Windows to recognize the memory. So I put the memory in how I wanted it, PNY 1GB's into "Channel A" and preexisting 512MB's into "Channel B" and booted into the Windows Safe Mode by pressing "F8" multiple times after the BIOS screen. Low and behold, Windows gave me a "New Hardware Found" dialog box and indicated it was memory. Therefore, I rebooted to get out of the "Safe Mode" and Windows went straight to the Windows login screen.So now both PC's are working wonderfully with a total of 3GB of memory and both are using the memory at different speeds (533MHz versus 667MHz) without issues.Note: I moved the memory because the computer tries to utilize the "Channel A" memory first and having a larger amount of memory there means my computers would run "better" even though all the manufacturer instructions explicitly told me not to do it. In addition, what happened on the Dell E521 could have been narrowed down to just the addition of memory as a single change versus multiple changes like I made...maybe they knew what they were talking about. ;-) ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great Value RAM for A Optimal Price *by J***Z on Reviewed in the United States on April 15, 2012* This is not the first time I have bought PNY RAM. In fact this is the 4th or 5th time I have purchased PNY RAM. I buy PNY RAM because it is one of the cheapest in the market and it is also one of the best performing RAM companies in the market. When I am building a gaming PC or a high performance PC I usually buy much more expensive high performance RAM, but for normal everyday desktop PCs this is the way to go. I just recently bought a low-end Dell PowerEdge 840 server that does not require that expensive server RAM. It only requires normal 667 mhz PC2-5300 DDR2 DIMMs. It maxes out at 8GB of RAM, so that is what I purchased. This RAM even performs great in a low-end server. It can handle all the common tasks of a normal power user, checking email, surfing the web, and creating documents. It also handles all of the tasks that a low-end server is used for. I use this server as my primary domain controller on my network since domain controllers do not need a lot of resources, 8GB of RAM is overkill, it only uses 1GB of RAM at any given time. It is never too early to plan for the future when it comes to computers and servers. So to sum it all up, PNY RAM works great in my low-end server. It performs just as any other expensive PC RAM would for almost half of the cost of the other RAM out there today. I will definitely buy more of this RAM if I ever need more. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Good purchase, solid hardware *by M***1 on Reviewed in the United States on September 3, 2010* I purchased this memory upgrade for an older desktop in use at home. I received it quickly, and in good condition. Installation was easy, and the detailed instructions included in the packaging would be helpful for someone unfamiliar with adding peripherals to a system. Overall, performance is good, speed of my desktop has definitely improved. I would recommend this product to anyone looking to boost their desktop memory capabilities at a (relatively) low cost. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1784413-pny-optima-4gb-2x2gb-dual-channel-kit-ddr2-667-mhz](https://www.desertcart.tn/products/1784413-pny-optima-4gb-2x2gb-dual-channel-kit-ddr2-667-mhz) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-16*
