Product Description

Capacity: 4 GB

DDR2 is the next generation of DDR memory. DDR2 memory features faster speeds, greater bandwidth, lower power consumption and enhanced thermal performance. Although DDR2 modules are the same physical dimension as DDR modules, the plug-in connector configuration is different and as such DDR2 modules are not compatible with PCs requiring DDR modules, and vice-versa.

The ram I received from "NEMIXRAM" was not what is pictured/listed. Instead of receiving the ram in retail packaging, I received an OEM version. The RAM's were just in a static bag in a padded envelop for delivery.

Also, the item listing stated KD2-800 version. The part# for the ones I received ended with SD2-800. Instead of returning it, I decided to keep it since this will be used to upgrade someone else's NON gaming pc.

I am currently running memory test (memtest86) on both sticks. 8 Hours so far without any errors. I will be running it for at least 24 hours to thoroughly test both sticks and will post an update if the test shows any errors. The ram's latency is 6-6-6-18 when running at 800MHz / PC-6400. Keep in mind the KD2-800 version is stated to be 5-5-5-15 at this speed. I've tried to change the latency to 5-5-5-15 to run the tests, but both sticks defaults back to 6-6-6-18.

If you are going to order this ram, try the other seller besides NEMIXRAM. They might actually provide you with the correct version of this ram as pictured as well as the correct model ram.

Update 2/20/14: After running the test for 24 hours, memtest86 spitted out errors when testing at 800Mhz at 6-6-6-18. This leads me to believe that these sticks are NOT rated for 800MHz. I am testing both ram sticks at 667mhz now. According to memtest86, the default latency at this speed is rated at 5-5-5-15. Will post another update if errors are generated at 667mhz.

After installing the 4 sticks of RAM my computer would not boot up. It did the typical series of beeps which indicate bad memory.

I ran Memtest+ on each stick one at a time. Of the 4 sticks, one failed the test after the first pass. Contacted the seller "Xtreme Ram" and they responded promptly to go ahead and return the single stick for a replacement. I did so (on my dime) about 2 weeks ago and have not heard back.

The seller "as well as myself" are located in CA so I don't imagine the replacement should take too long. After all, the original order only took two days.

I am currently running the 3 good sticks of RAM in my PC (6GB) and everything is fine.
I will update this review when/if I receive my replacement RAM. If I don't hear back by this Friday, I will file a claim with Amazon.

*UPDATE*
Received the new stick of RAM. Threw it in with the other 3 sticks (totaling 8GB). Booted up fine but then Firefox, VLC, and IE started crashing after minutes. Then I got the memory dump blue screen. Forget it, I'm just going to return the whole order.

Put my old memory back in (4 sticks at 1GB each) and the computer runs flawlessly again. The old memory is a slightly slower speed and I checked the MOBO compatibility and this new memory should have worked. Oh well...
Will report back if the refund/return goes smoothly.

*Update 4/17/2013
Seller refunded all money with zero problems. Never did figure out why 3 sticks of memory worked but not 4. I ran out of patience on an already decent performing machine.

Very pleased with this order! Received my order on time, nothing damaged in transport. Just popped them in, fired up the computer and I was good to go :) Everything loads so fast now, and my games and chats don't lag or freeze anymore! Will order from this seller again when I upgrade my son's computer for Christmas.

I purchased this memory to upgrade our server to 8 gig. The order came in two days packaged in a bubble shipper. I inspected the chips under magnification for damage with none found. The line number matched and the serial number was less than 100 difference. This spec was important to me since it was filling dual channel slots. I am happy that it was not grab from a random box to make a sale. I like to think that the seller was paying attention to this so they ship matching memory.

The specs of the memory were true to the description. It is too bad there are no heat sinks, this would have been a bonus.
I will buy again and recommend to people I know.

It's 800MHz memory which has been out for a while now. I purchased this to upgrade a budget machine from slower 2GB to this 4GB set. A fine solution for the money. I have read some reviews here about latency not being up to snuff but this is budget RAM, what do you expect? The machine it was installed in can now do more tasks at the same time with no observable lag. It does what it's supposed to do. Budget.

I didn't know what rating to give this product... as the RAM is here, it works... but it is not actually the RAM in the picture. It is PNY RAM that I received, not my beloved Memory Master. (not beloved, kidding.) While I'm glad it was shipped and arrived quickly, and it works, it seems to me that I should have been sent exactly what I paid for, no? Sure, it caused me great pain to try to decide exactly what brand of RAM I should get, wondering what truly is the difference between all these lovely RAM companies. But hey... that's beside the point.

I can just hear the seller mumbling under his/her breath - "Eh, this'll do."

Well, I'm going to run some tests on this RAM and see how it stacks up - the CAS latency, etc.
