Review: Excellent RAM; great price - I have an old but extremely functional Dell Dimension 4550 that now has new life. After upgrading the BIOS to AO8 I ordered the PNY Optima 2GB (2x1GB) modules from desertcart which I received in a few business days. desertcart's new easy packaging initiative is a welcome process. The box was just the right size, afforded proper protection and was easy to open. Insertion of the RAM into my PC was quick and very straightforward. After closing the case I powered up the system and the RAM was instantly recognized and performed flawlessly. System Info and Belarc Advisor both testified to the full 2048kb of RAM. The newest version of Turbo Tax, which somewhat overwhelmed the previous 1GB (2x512MB) modules, now performs smoothly with the additional RAM. My only complaint is the vendor packaging. The RAM is well protected but, as with most electronics these days, the only way to open the plastic is to cut it open with scissors or utility knife. In addition to the added difficulty, the possibility of damaging the RAM while cutting it open creates considerable angst. All in all however, the PNY RAM filled the bill. Highly recommended. Review: Made A Noticeable Difference - I own a six year old eMachines 6410 with Windows XP. After a household youth downloaded several programs, videos, and music files, the system crashed. I removed most of the downloaded programs, transferred the document/music/video/picture files to an external drive, cleaned the registry, searched/removed malware, then defragmented the hard disk. The system performed but it was slow. With a few windows open (Internet, MS Word, file search, messaging) the windows required repeated mouse clicks and patience to change/exit. The windows would scroll fom top to bottom to close. This system had 384 MB of RAM. I ordered the PNY Optima and the difference is notable, not just to me but to others in the household who were complaining about the slowness of the system. Windows just blink to close and almost pop when opened. It was really worth it for a student who is trying to multitask. Installation was easy. Open the case and install. Follow the instructions. It took less than 10 minutes. Be sure that your computer has been optimized for speed with system cleanup and maintenance first. If there is still the need for speed, more RAM might do it for you. Ensure that this type of RAM is compatible with your machine. There are plenty of site on the Web where you can find out. ## Features - Memory capacity upgrade provides improved system performance and responsiveness - Deliver all the productivity your PC has to offer with PNY Memory - Compatible with PC3200 (400 MHz), PC2700 (333 MHz), and PC2100 (266 MHz) systems - Helps prepare your PC for running Windows Vista - Easy installation, Free 24-hour Technical Support, and Lifetime Warranty! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00076ZUZM | | Additional Features | Lightweight | | Best Sellers Rank | #12,616 in Computer Memory | | Brand | PNY | | Compatible Devices | Desktop | | Customer Reviews | 4.6 4.6 out of 5 stars (955) | | Data Transfer Rate | 400 MHz | | Form Factor | Desktop | | Global Trade Identification Number | 00751492226484 | | Item Weight | 0.1 Pounds | | Manufacturer | PNY | | Memory Speed | 400 MHz | | Number of Pins | 184 | | RAM Memory Technology | DDR4 | | RAM Size | 1 GB | | UPC | 021111179270 846764219063 088021274938 151903064412 751492226484 078667264141 521227116058 763615923057 132017637532 021113078380 086000565633 071030620124 523160899333 001910719273 163120296699 | | Voltage | 2.5 Volts | ## Product Details - **Brand:** PNY - **Compatible Devices:** Desktop - **Computer Memory Size:** 1 GB - **Memory Speed:** 400 MHz - **RAM Memory Technology:** DDR4 ## Images ![PNY Optima 1GB DDR 400 MHz PC3200 Desktop DIMM Memory Module MD1024SD1-400 - Image 1](https://m.media-amazon.com/images/I/61YymWnLBBL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent RAM; great price *by T***N on March 29, 2011* I have an old but extremely functional Dell Dimension 4550 that now has new life.

With the 2GB of memory provided by these(max for the Dell Dimension 4550 P4 2.4GHz system)I'm able to stream video off the internet and still run other apps in the background. This is good memory, not the fastest around, but good memory at a reasonable price. --- ## 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.co.th/products/5353619-pny-optima-1gb-ddr-400-mhz-pc3200-desktop-dimm-memory](https://www.desertcart.co.th/products/5353619-pny-optima-1gb-ddr-400-mhz-pc3200-desktop-dimm-memory) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-29*
