Hi, right im gettin memory errors on my pc and have run memtest86 for 2 hrs and found no prob. But ive been toying with gettin some G.skill, i currently have 1gb of Kingston Value Ram, my 2500-m is @ 2500mhz (195x13) on a dfi infinity i usually go by the rule more = better and thus was thinkin of going for 2gb of memory... i want this mem to last so i will be using it in my next few systems (thus was thinkin 4800) which of the following would you get if prices isnt too much of a option ( ~<£400) 2x512mb DDR 4400 2x1024mb DDR4400 (if anyone knows if this is possible please say, and where to get it ) 2x512mb DDR 4800 2x1024mb DDR4800 (as again please if and where) 4x512mb DDR4400 4x512mb DDR4800 Also can you please post your views on G.Skill memory Thanks N4N01D
that wouldnt run @ dual chan tho, also was it when you put 4 sticks in it runs at 3200, its stuff like this i aint 100% sure on.
Actually, on most AMD64 systems, 4 sticks will run at PC2700. I vote 2x 1024MB DDR4400 (if you can find it).
If you're running a 2500XP-M on a DFI Infinity (assuming NFII Ultra obv), doesnt that limit you to 3 sticks? So I'd say 2*1024mb PC4400, or just some 'plain' old cas2 PC3200 if you're not going above 195mhz
yea it is only 3 sticks in my dfi, but my next board will have 4 , but the only reason im at 195 is my mem wont let me go any higher, if i could i would these are the only sticks of 1gb ive seen over 3200 so far, but they aint matched either and are only 4000 http://www.crucial.com/uk/store/MPa...304&WSMD=NFII+Ultra+Infinity&WSPN=BL12864Z503
In that case, if you really want to push it, I'd probably recommend 4*512mb, as 512s will overclock better than 1024s. Maybe 4*512mb OCZ VX
2x512mb pc4400. 4800 is overkill, 4 sticks is rubbish for overclocking, and you only really need 1gig of ram, 2gig is just overkill
i'd use 1gb of ram quite often, also it was my way of future proofing it... were all going to end up with 2gb of memory sooner or later imo alastor - 4 x512 will runn at 2700 so even to get them to 195 will involve oc'n :S
Have a sneeky feeling you might have issues finding 2*1gb sticks at 4800/4400 tbh. Highest I've seen is 3200. It really depends what you're after tbh, 4*512 will default to 166 and 2t most likely which will kill performance. However 2*1gb sticks will more than likely clock like crap. Running the 166 divider on A64 isnt too bad, you can still hit 300 htt, and have the memory running at 250. This would be faster (most likely) than crappy 1gb sticks stuck down at 200/220 running 1t. If you get a good mobo (dfi for example) 320+ htt shouldnt be a problem, allowing you to run the memory even faster on the divider. However 4*512 is gonna put some serious strain on the mem controller, so its a case of swings and roundabouts running the 2gb route. IMO the best bet is to get a gig of whatever now, and if you find you need more memory add another at a later date. No doubt, in the near furture we'll start seeing higher density chips on some of the faster modules... Either that or everything will do ddrII....
same as this guy.... still totals just over 2gig and so windows wont b***h about it either!!! i mean i know u said money is of no relevance, usually is with ALL of us monkeys in here , but even 1gig would do you easily unless ur doing some serious 3drendering work or similar pro work. either way enjoy timing the sticks ....
ok what? 2 GB???? what the f do u even need that for, i hear a waste of money, u dont need it for any software out there except like msf2005 but do u even play that or have a graphics card to make it run as smooth as u expect youre memory to run it? think in 3 years when that will cost jack **** because 20gb ram chips will be out lol, but yeah i would just wait and find out what ur really gonna need it for.
Well, playing HL2 or doom3 witha 6800GT and 2 GB of RAM (provided the processor isn't too slow ) would prolly make the best gaming system available right now I wish I had that kind of money.
well the thoughts were 2gb because - 1) i do a lot of large image work 2) the system is sometimes used as a domain controller/fileserver/exchange server etc 3) this is also a gaming system. 4) i do a lot of movie encoding/re-encoding these are the main reasons i can think off the top of my head.
Ok, If I may insert some thoughts here... 1) You run an AMD system. This means that timings rule, speed does not. Save the high FSB for us intel boys, and go for some CAS2. 2) Go with 1 gig, then see if you really can benefit from 2. Chances are you won't. Even with the large image work, most of that work gets passed off now to various spots in the system (I am using maya and worldbuilder on at least a weekly basis, and I don't think you'd be running more complex than the leading render software for movies). It goes to the GPU for part, the CPU for the other part. That sharing removes the need for such gross excess of ram. If you were truly running an image powerhouse, you'd be using a Quadro anyways instead of a 6800. 3) Since timings rule more than FSB, 4 sticks dropping you down to 166 won't be crippling, but it won't be good, either. You'd be better having 2 sticks for your games. And 4 will overclock HORRIBLY. Overall, I would say just go with a gig of the PC4000 in CAS2. If you really want to spend money, buy it ECC registered for the boost in performance you're looking for. That alone will swallow nearly your 400 pounds, but it will melt anything that comes close to it as far as ram speed goes. Also, most of the work you mention requires small packets moving quickly through the ram (file sharing, encoding, etc). This is not a function so much of the FSB (which control how quickly large blocks of data move into and out of the ram) but of the timings, which count how many clock cycles it takes to move a byte from point x to y. Hopefully that helps.
I would agree with everything you said but this. There's no reason to get ECC registered, except for a huge server environment. The ECC drops every timing down one setting, so instead of running 2-2-2-5, you're running 3-3-3-6, and that's the fastest you'll ever get. Besides that, it's not worth it for gaming. Like you said, timings are king, why sacrifice them for a bit of useless error checking ?
Correction, zephyr is right. The best ecc/registered ram you can get at CAS2 right now is pc3200 (that I have found) after double checking that...for pc4000, the tightest I can find is 3-6-3-3. And Zephyr, the reason for ECC/registered is because the error check/register process DOES increase the overall system speed, because the ram is passing on high fidelity information (less drops and reloads) at the same speed that normal ram could pass bum info. I'd love to explain this in more detail, but it would take a page or two to explain it and a proofread by my Electrical/Computer Engineering friend (who works on some chip design) correcting the parts I still can't quite wrap my head around. But, that won't account for the difference in timings when the lowest available is 3-6-3-3.
