RAM Question

Currently, I am running a GA-7N400 Pro2 MB with an AMD XP-3200 (Barton) and a set of Dual Channel Hyper-X DDR400, for a total of 2 gigs. My question is that I have 4 RAM slots with the capability of carrying a total of 6 sides of RAM. (The Hyper-X is dual sides for a total of 4 so far) I have 2 sticks of Kingston DDR-400 (2x512) value RAM (single sided). Can I use the value RAM WITH the Hyper-x for a total of 3 gigs? The Hyper-X is overclocked very mildly and would that effect the value RAM, which has NO OC capabilities? Would installing the Value RAM cause the Hyper-X to default to the timing value of the Value RAM? Or would it be better to re-set the Hyper-X to default timings and then install the Value RAM? I figure that 3 gigs of RAM is better than 2 gigs, even at the default timings, but I'm just not too sure if it would work.:confused Any ideas?? THANKS!!!!

 

Firstly I would DL and run CPU-z and obtain the SPD info of your Hyper-X, noting the timings and MHz (eg. 4-4-4-10@400MHz);

You may find that the Kingston has different timings at that speed (MHz) and therefore require you to set the timings in BIOS for "all" modules to get them to play well together.

 

Even if you don't set the timings, the different types of RAM should all run together without issues. However, adjusting the timings is a good idea in order to optimize the memory's performance, but this step isn't required, but it is recommended.

 

The one thing to pay attention to is if the HyperX needs a different voltage than the value RAM. If it does, it is not recommended to run them together, since all four modules need to run at the same voltage and timings. The motherboard treats RAM as one single unit that runs at the timings and speed of the slowest installed module.

If the HyperX needs a different voltage than the value RAM, then you will end up giving either too much voltage to one pair of memory or too little. Either way, it is bad and can hurt the memory, so check the voltage. You should be able to find spec sheets on Kingston's web site.

 

First of all, I need to apologize to the people that answered my question. You see, I posted this the day we left for San Diego on vacation and have just returned. Actually, I just returned yesterday, but my 8 year old wore me out totally and was just too darn tired!! Again, sorry for not acknowledging your replies!!

Okay, I downloaded that little program and it was quite helpful...thanks Bold Eagle!! To make a long story short, I got it all working except for the one stick of 512, so I'm only running 2.5 gigs of RAM, but I' satisfied!! However, one thing does have me stumped. Why would I want to run my RAM @133 when it's rated @200? That program told me how to set the timings for 133, 266, and 200. I left it at 200. Is there a reason for wanting to run it at a slower speed? Just curious!!

Again, I do apologize for not getting back to ya'll sooner, and I do thank you all very much for your replies...they were very helpful!! Okay, time for a GROUP HUG!!!:-D

 

I upgraded my processor 4 months ago from a 805D to a Q6600. The Q6600 has a slower rated clock speed then the 805D but because it is a quad it runs faster and better. I can lower my RAM speed to match it with my Quad core to maintain a 1:1 ratio. Personally it is better to have faster RAM and run it at lower speeds, allowing for more head room at a later date if you ever want to OC the CPU. I will be undertaking a cooling project soon to increase the thermal management of my case, stripping motherboard chipsets, increasing case inflow and building a memory cooler which will then allow me to increase my CPU clocks and I wont have to OC my RAM as it will be running closer to spec.

Bold Eagle, you mentioned a memory cooler. What does that consist of? I'm using an Antec P-180 case with 4 120 fans on high, so I really don't have a cooling problem, but that memory cooler sounds like something I could probably use just to make sure I have NO cooling problems. I was told that the Hyper-X Dual-Channel has a tendency to run hot. I've had no problems yet, but then again this is only the 2nd day I've run this RAM and alittle extra protection sure wouldn't hurt!! THANKS!!! Oh yeah, and thanks for explaining that thing about running faster RAM at a lower speed. Believe it or not, I actually understood that!!:-D

 

I found this RAM cooling build recently and thought I would give it a go, the best part of it is it will be as good as the fans you buy and should outperform most commercial memory coolers I have seen at a fraction of the cost (plus you can disassemble and replace individual fans if ever needed). Furthermore my motherboards warranty has expired so time to rip of NB and SB HS and replace with quality TIM and mod them a bit.

HOW TO MAKE YOUR OWN MEMORY COOLER

You may have to chase down parts with different measurements (imperial) but you will get the drift, just remove one of the motherboard mounting screws and ensure that your longer screws will properly thread into the spacer and your set.

As you started this thread I don't feel like I'm hijacking :-D:-D.

 

Well, here I am...late again!!! Thank-you very much for the link and pictures on making a memory cooler! This is one project I'm going to undertake and, like you, my MB is long past the warranty period. If I do happen to screw it up, that won't be a problem because I have another new, identical board in the computer room. I bought 2 because I was going to build my son an identical system, but his grandfather bought him a new Dell desktop instead.

I have the fans already and just need to find those rather lengthy screws and stuff. Granted, 2 80s may be a bit of an overkill in my system, but one things for sure....I won't have an overheating problem!!

Again, thank-you for replying and for the link. You have VERY helpful and it is much appreicated
