JestaGeek Posted December 11, 2008 Share Posted December 11, 2008 These are the memory modules that I originally used: RAM » DDR2 240pin G.Skill DIMM Kit 4GB PC2-6400U CL4-4-4-12 (DDR2-800) (F2-6400CL4D-4GBPK) (Quantity: 1) 2x 2048MB Module, 2.0V-2.1V, Lifetime guarantee Unfortunately, I've placed an order with an online shop here in Germany for another pack of these, as well as a replacement for my optical drive which quit working a while back, but both items are out of stock all of a sudden, and they don't give an estimate of when either will be back in stock. It's simple enough to find a replacement for the drive, but I'm not sure how much flexibility my motherboard and/or BIOS provides for mixing and matching RAM. I'm using a Gigabyte GA-EP35-DS4 mobo with the aforementioned RAM running in dual-channel mode. I have a couple of options for similar modules from other makers: 4096MB-Kit GEIL Ultra+ PC2-6400 DDR2-800 CL4, 1,9V-2,3V http://www1.hardwareversand.de/1Vo_lKEa8Vu...41&agid=599 4096MB-Kit Mushkin XP2-6400, CL4, 2.0 - 2.1 V http://www1.hardwareversand.de/1Vo_lKEa8Vu...18911&lid=2I think this might be the same as this item on Newegg.comOr would it be better if I'm either patient (and wait for my exact G.Skill RAM to come back in stock where I've ordered) or cancel and find that elsewhere? If anyone has experience with running two brands of similar RAM on motherboards similar to (or the same as) mine, I'd appreciate any feedback you can provide. Thanks in advance to any who reply.

MacNutty Posted December 11, 2008 Share Posted December 11, 2008 While adding new RAM the only thing which you have to care for is the bus speed. If your existing RAM is of 800 MHz then RAM with any brand of same speed would do. Also keep in mind that while adding RAM use the slot near to the earlier one.

If your existing RAM is of 800 MHz then RAM with any brand of same speed would do. Also keep in mind that while adding RAM use the slot near to the earlier one. Sometimes you need to set the timings of the ram to manual in the BIOS then use the highest timings of the set of ram that will be in there as some boards will get confused by seeing two different ones or the higher timing ram cannot be run at the lowest in there if the board defaults to it, plus you want the voltages set to the highest value of the different ram sets put in.

Thank you both for your replies. I ended up canceling the order, and was able to find another company which had my existing RAM in stock as well as the DVD drive that I wanted. I'm hoping that by increasing my RAM to 8 GB, I'll be able to run more applications better without as much need for virtual memory. With the new drive, hopefully I'll also be able to experiment with Boot-132. Thanks again to both of you.

As they say you can never have enough ram plus it is dirt cheap for DDR2 now a days so why not fill er up.
