I have Dell Dimension 4700 with 1GB RAM module installed. This system uses DDR2-400 (3200) RAM modules, up to 4GB, according to Kingston.com. I bought 2GB RAM, made by Gigaram, 256MX72 PC2-3200 DDR2 ECC REG, 128MX4, 2 Ranks. This module perfectly matches the Dell module I've already got under the hood. Both dual-sided, both same pin configuration.

When I put in the 2GB RAM module, either in combination with the old one, or by itself, the computer would not boot up, and starts beeping. One long, three shorter, then pause, then two more, sort of long. I am thinking, the RAM module I bought is defective. I've tried inserting it by pressing on one end, then another. Tried shifting it. You name it - I've tried it.

Should I return this for a replacement, or should I just request refund, lose the 20% restocking fee, and ask Dell for the same module?

Thanks ahead of time.

Wow, here's something interesting I just found out.

The RAM module I've received from Newegg is ECC and Registered. Also, it is a 2GB RAM module. Newegg told me to call the manufacturer for help - and guess what....

Apparently, Dell Dimension 4700 uses non-ECC, non-Registered RAM, and only in 1GB increments (that's why it has 4 slots, for a maximum of 4GB capacity).

At first, I was upset - but Gigaram offered to send me 3 GB of correct RAM in 3 modules, if I shipped them the 2GB module - at no extra cost!!! Turns out, the ECC/Registered DDR2-400 RAM is a lot more expensive than non-ECC/non-Registered.

Anyway - I love happy endings. I just wish there was a place somewhere on the web (perhaps on Newegg website - duh!!) telling the consumers EXACTLY what they need to order to prevent situations like this one.

I hope this article will help somebody else like me!

Thank you.

Crucial is good at this at:http://www.crucial.com/

Along with Crucial, as gunner suggested, there's also Kingston, and Corsair.

All of these companys make quality RAM.
One place you don't want to be cheap with the money, is the RAM.
Also, check out the info on their sites, there's a lot of good info about RAM.
Definitely worth the read.

This is what I found on the Dell Dimension 4700 Series.
MOBO: GIGABYTE GA-MA790X-UD4P, CPU: Phenom II X4 955 Deneb BE, HS/F: CoolerMaster V8, RAM: 2 x 1G Kingston HyperX DDR2 800, VGA: ECS GeForce Black GTX 560, PSU: Antec TruePower Modular 750W, Soundcard: Asus Xonar D1, Case: CoolerMaster COSMOS 1000, Storage: Internal - 2 x Seagate 250GB SATA, 2 x WD 1TB SATA; External - Seagate 500GB USB, WD 640GB eSATA, 3 x WD 1TB eSATA

Ok, the saga continues...

Just received the 3 GB RAM modules - new ones.

Plugged them in, computer reported in the beginning of boot-up that new memory is detected, press F1 to continue or F2 for setup.

Went into Setup - it shows 4 modules in, 2 ranks, everything nice.

Computer booted up, just opened windows - boom computer shut off and started making beeps.

I turned computer off, and reshuffled the ram modules - put the original one in the opposite slot, and the new ones in remaining slots. Computer booted up fine (hence I'm on it right now), but in Control Panel only shows 3 GB RAM instead of 4GB.

Before I do anything stupid - anyone have a clue as to what's going on? Did the old RAM module become jealous and revolt??

I suspect the slot (since the mobo works in one config, but not another).

Try one of these free, floppy based memory testers:


Run for a minimum of 2 hours (overnight is better) - then swap the sticks around and test them there. Also, you can try testing just one set of the sticks, then testing the other set to help to rule out the sticks and isolate it to the slot on the mobo.

Well, unfortunately...it may have to do with the fact that Windows can only see 4gb of ram period...system ram, and virtual ram. Since you have 4096 of system ram, and your pagefile is on...you've passed the Windows memory limits. Remember, Windows sees the pagefile as system memory.

The only solution you could try to get Windows to see all of your ram, would be to shut off the pagefile. Not recommended but could just to see what happens.

Also take note, that with 4 x 1 gig memory modules, the latency (clock cycle time) is slower than 512mb modules. Your system would perform faster with 4x512mb (2gig), than 4x1gb (4gig).
