FS/FT: G.Skill DDR550 2x512mb TCCD RAM

[Kougar]

Looking to sell these, or possibly some kind of trade:

G.Skill DDR550 (PC4400) 1GB (2x512 Dual Channel) Samsung TCCD RAM.

Rated Timings:

DDR400 @ 2-2-2-5
DDR550 @ 2.5-3-3-7

Rated voltage specs: 2.7-2.9v
ECC: No
Unbuffered
Lifetime G.Skill Warranty!
Original Retail packaging included

I'm currently looking for $100 shipped (Insured) to anywhere for these. If anyone is interested complete info these and what I might be willing to trade for is over HERE (http://forums.anandtech.com/messageview.aspx?catid=45&threadid=1898095&enterthread=y)

I can't do anything with these, and am sure there has to be someone that is taking advantage of AMD's price slashing that could use the tightest DDR550 timings out there... ;)

Just so you know Kougar, that link you posted doesn't work ;)
BTW weren't these the sticks your motherboard had some issues with?

[Kougar]

Err, I did that intentionally to see if anyone would notice... yeah, that's it. :-P Thanks Gibson!

Yes, these infact are the same sticks... hence why I'm finally getting rid of 'em! I mentioned most of the details in that thread the link is to though... the RAM would run just great at 2-2-2-5 timings, but I never got a stable anything else unless the timings were put at 3-4-4-8 timings either due to a motherboard issue or the simple fact I couldn't give these the full voltage they required. They are rated between 2.7 and 2.9v, and from some digging 2.85v seems to be best for lighter overclocks. My motherboard tops out at 2.8v exactly.

I should have known that there was likely a reason G.Skill was not listed on Abit's website for supporting the IS7 series at the time I bought these... ;)

Too bad nobody seems to be interested, I think most people are holding on to get a conroe rig. I would have considered your offer if I'd had value ram, but I'm running 2gig of corsair ram which is rated at 2-2-2-5. Strangely enough it's only rated 2.5 instead of 2 on an AMD rig (don't ask me why, the info that came with it said so) The SPD seems to run it at 3-3-3-8 atm. Maybe I should look into lowering those?

[Kougar]

AMD rigs are very sensitive to latency, so yes you should try lowering those a little if you can. I didn't see your RAM config listed in your sig, but one problem with using 4 modules of memory on a rig is that it almost always requires more relaxed timings on the memory. If I'm correct in that you are using 4 sticks of RAM, then they might actually be the best your motherboard can handle... but it is still worth a shot trying to lower those. A DFI board should be offering better timings than those regardless of the config, if all the RAM is rated at 2-2-2-5.

Nope, I'm running 2 1Gig sticks. Yes, I think they should be able to run lower timings. Remember they are rated at 2.5 for amd systems (anyone know why? as they are rated 2 on intels). One thing though, can I try lowering them without my xp install getting at danger. I wouldn't like losing everything while trying to lower timings ;-)

[Kougar]

Well, ironically enough this is one big plus for having Vista... it has a built-in memtest program you can run at start up before Vista loads...

In most cases booting into windows on an unstable system won't do anything more than cause a crash or glitching that a reboot back to the previous settings can't fix. But there is always a small degree of risk of some fluke thing happening during a crash to futze your OS install.

So your best bet to play it completely safe and get a definitive answer would be to force lower timings in the BIOS, and then boot memtest off of a CD and let it run to find instability. ;) http://www.memtest86.com/ (http://www.memtest86.com/) 2.5-3-3-7 shoudl work fine, and 2-2-2-5 might work, although a little extra voltage might be needed for compelte stability. You'd need to research your exact make/model of RAM before playing with their voltages though... ;)

His DFi board should have MemTest in the Bios, just enable it and save and go. Some Corsair ram is really strange in AMD boards, but like you said, set it to the lowest setting (2-2-2-5) and give it a shot.
My 2 gig of OCZ will only do 2-3-2-5 at DDR400 speeds but will also do 3-3-2-8 at DDR500............;)

Well, I knew it had memtest built in. But what I want to know is that nothing can go wrong with my install if I boot with memtest turned on?
If I'm not mistaken I'm running TwinX2048-3200C2 which is rated at 2-3-3-6.

No nothing should go wrong. Its like using memtest on a bootCD.

With MemTest enabled, the system will boot into memtest so you can run your tests on the ram. When you're finished, you need to reboot and go back into the bios to disable it again so you can boot into windows. This totally isolates your HD from the testing.

K, thnx for the info. I'll try it out as soon as I get some spare time.
BTW, sorry for hijacking your thread kougar *blushing*

I don't care... I see it as getting free advertising anyway :-P

BTW, this memory does 2.5-3-3-7 at DDR550... :mrgreen: Just that I ran out of overclocking room at DDR500 and was effectively undervolting this stuff to begin with... :roll:

Voltmod the hell out of that board! :mrgreen:

[Kougar]

If I had the right tools and knew what the heck I was doing... maybe not till after I get a second system incase I wreck this one though. :-P

I can't even raise the MCH voltage though anyway, which would guarantee me a few hundred more mhz off this CPU I'm sure. I'd have to volt mod so many things it'd be ridiculous... And I'm not sure if I've seen any that work for a IS7 anyway... the IC7 is to much of a different board. ;)

I've read a few how-to's abou the topic and doesn't seem THAT hard if you know how to solder. It's basically soldering a variable resistance onto the board. But I agree there can go a lot wrong, certainly if you haven't ever done this kind of thing (I haven't either ;)) Though if you ever do get to doing a voltmod, let us know the results! ;-)
