RAM problems..

Ok, so I moved my computer from my office back to my room, and now I only get 1 gig of RAM anymore.

The BIOS only detects one gig, in single channel (1 stick), instead of the two.

I was running a virus scan and noticed that It was abnormally slow, and I checked the Memory usage bar and it said 77%, and that I was using 700MB, so I was suspicious. This is how I found out about this issue.

So I ran the Built In RAM test that the BIOS gave me and it turned up as 0 results, I took my RAM out and blew out the DIMM slots to get any dust out, and reseated the ram, no dice..

So what do I do? I'm hoping that one of my DIMM's isn't dead.. then I'd really be in big trouble, I'd need a new motherboard.. *sigh*, I'm not fond of mem-test or if it will even work, if you recommend it then I'd need directions to set it up.

Any help or suggestions is appreciated, thanks.

EDIT: Just to let you know, I was extra careful when moving my computer, I always am - to make sure my hard drives don't get bumped and stuff.

I'm going to start up some games and see if I BSOD or lock up, so far I only had one lockup (while my virus scanner was on), not even sure if it was a lockup, maybe Vista + the scan made me run out of memory, who knows. I'll report back with results.

Ok, tried Call of Duty 4 for a few minutes, and Guild Wars too, no crashes yet.. just insanely slow, tons of lag. You really can't use Vista on 1 gig.

Did you build your computer yourself? Sometimes some brands of memory aren't compatible with certain brands of motherboards for whatever reason. The memory may quit suddenly after working just fine for months. Instead of a new motherboard, you may need new memory (from a different brand). It's hard to say without knowing what the specs are on your computer though.

If you can state the specs on your computer, people maybe able to give more specific help.

swap the memory into different dimm slots. if the bios doesn't recognize the ram in a different slot then bad ram, if it doesn't recognize the good ram in the other slot bad motherboard.

also might want to check for a bios flash for your motherboard if they have one. that could possibly fix it too.

I found the problem.

It was RAM stick #1 in DIMM slot #1, computer would not boot with only that stick in. I put RAM stick #2 into DIMM slot #1 and the computer booted.

So basically I'm going out to buy new RAM, and yes I built my computer myself.

I think I'm going to buy Corsair X2 1GB sticks next, the ram that died was 1GB of 800mz DDR2 Kingston Hyper-X gaming RAM.

*Sigh*

Or, does anyone have any suggestions for new RAM? I was thinking of going Corsair because I heard they are good.. but theres other brands too.

I personally prefer Kingston but Corsair makes great memory for gaming as well. Patriot is another good brand. They are keep their specs really close to industry standards, most others have far more leeway with their specs and qa.

If possible, also check your motherboard website. See if they have a list of compatible memory brands.

Having said that, basically agree with arch psyker.

Doesn't matter which path you go, XMS from Corsair or HyperX from Kingston, they're both fast.

Of course I recommend any of the Micron D9 chips, especially from mushkin.
Anything but valueram would be a good choice.

http://www.newegg.com/Product/Produc...82E16820145034 This is what I was thinking of getting, since my Kingston died I will take a new path and try out new RAM.

Not that I'm shunning Kingston cause it died, I just figure I'll try a change for once.

Kingston has lifetime warranty. Wrap it up, and send it back.

Those Corsairs are very common gaming RAM. They will do you proud.
They were also my first set of DDR2 RAM back in 2003. And they *STILL* make it, so they must have done something right

They don't overclock at all, if you push them, they'll fall, so don't try.

I don't OC anything and I really don't plan to, but yeah.

Sheesh that is old RAM then, but it doesn't matter, it's the speed and quality that I want, and it's what my Mobo uses so it doesn't hurt.

Objections?

Man, RAM got cheap. I recall forking over $140 a just a couple years ago for two 512 mb sticks of OCZ gaming ram (which at the time was good but not the cream of the crop).

Nope. I used it in my AMD 6400+ as well.

Perfect for casual gaming. I recommend it!

What's your take on 2X 2GB sticks? Then I'd have 4 gigs.

I want at least two sticks so I can do Dual Channel mode, but I don't know if having 2GB on one stick makes performance worse or not.

Hmm.

On paper, there is no difference. 2x2GB is better than 4x1GB because of two things, the obvious upgrade potential and less power consumption (4x1GB would cost more vRAM to power than if you were going 2x2GB).

But from experience, 2x2GB RAM often times perform slower than the 4x1GB counterparts. I'd stick with 1GB DIMMS (either 2x1GB or 4x1GB) because they're more reliable.

This is of course from my experience and research.

EDIT: More reliable: Yeah, by the time you'll need 8GB+ you won't be using FSB limited memory, or better(?) memory would be avaliable.

Figured, I'll stick with 2X 1GB then. I think I have my mind dead set on another pair of Kingston Hyper-X or the Corsair I showed you, but it won't be till Friday..

..So I'm on Windows XP now, thank god I still have it, always trusty. Can't run Vista with 1GB of ram, I lock up when I start doing simple things cause I just run out of memory heh.

Don't waste money on Corsair ram..... ewwww...

Say hello to Crucial Ballistix, the best RAM for the dollar on the market, period, end of discussion, please proceed to checkout and PC ecstasy land.

Here ya go:

Buy it. I run 3 PCs overclocked like crazy on this stuff. Rock solid, runs cool, plays nice with most overclocks, and can run at lower voltages at stock speeds, which saves power and heat. Did I mention it is a cheap as hell?

Can't run that Rahja, I need 6400.

http://www.newegg.com/Product/Produc...82E16820146565 If this version runs as good then I'll check it out..

What is wrong with Corsair though? I heard they have a good reputation for RAM.

Hmm, I'm checking CPU-Z and it says my RAM is volted at 1.8, and on the sticker on the RAM it says the Voltage is 2.0V.

Maybe it was under-volted and just wasn't running right, so I got problems? I don't know.. I'm too tired and pissed off tonight to mess with it, I'll try something tomorrow I guess.

As some guy said in a review on my RAM:

Other Thoughts: Per Kingston's website, this RaM will boot at 5-5-5-15 @1.8V and must be adjusted to 4-4-4-12 @2.0V to achieve best performance. Newegg lists the voltage as 1.95V, but thats not exactly correct. Enjoy! http://www.newegg.com/Product/Produc...82E16820134066

When in doubt, always add more voltage!

Nothing is wrong with Corsair. You get what you pay for, moderately performance for a moderate price! Corsair manufacturers most of their own RAM (if not all) so they're generally in a league of their own.

To be honest, unless you're a real enthusiast, you can probably live with the Corsair XMS2 6400's. There are so many different chips out there (not to be confused with DIMMs) and none of it would make a difference unless you plan to overclock (and you aren't).

Some manufacturers don't list voltages correctly because they don't make the RAM themselves, technology is not perfect, you can't go by the label, you have to figure out what works best!

Those Corsairs XMS2 6400's I had booted fine on Auto @ 1.8v for as long as I had them... I found it weird that customer support told me to run them at 2.1v when 1.8v ran just fine. If you haven't upped the vRAM in your BIOS, then thats why it's running at 1.8v instead of 2.0. *YOU* have to manually up it.

Well, that's just it.. they booted happily and have ran for 4 months that way happily and I've had no problems with it, but apparently on the sticker, and on the site, it says go with 2.0 volts.

But I really do think that stick is dead, if the computer won't boot from it then there is nothing left of it, but I doubt an under-voltage killed it. RAM just goes iffy sometimes, not much you can do about it.

Did you try what Admael said? I fried a stick of Corsairs XMS by my own fault and they didn't ask any question. They only ask me to run a memtest+ and when it failed they send me brand new sticks. You should talk to Kingston to make sure they won't pass on the warranty.
