Buying FAST Memory

Madgoat1979 · Feb 21, 2003, 09:27 PM

OK,

I have a couple questions.

First, I have a 266ddr Board... I ovclock and would like to get some memory that can hold up to at least 150fsb (300ddr). But I also would like to use some nice Ram timing's.

So the question: Can I buy (instead of 2100 ddr) say, 2700 or 3200 ddr ram and run it under speed and pump up the timings? would that work, or does ram run certain timings that its said too no matter what the FSB?....

So basicly I want to overclock from 133fsb but keep memory timings up while not having stability problems.

Right now i have 512mb of 2100ddr and it cant handle over about 140mhz (and thats with slow timings.). I want to hit (and stay at) 150 (300) .... but I know it my memory in the way.

COuld someone point me in the right direction for memory??

thanks,
Peace,
MadGoat

Yes generally, if you buy faster-rated RAM, you can push your memory bus and memory timings faster and stay stable.

But I think your board may hold you back . . .
the K7S5A wasn't meant to be overclocked, so if new RAM doesn't help much, that would probably be the factor.

But I dunno how fast K7S5A FSB's have been successfully run at; perhaps you know better than me

Madgoat1979 · Feb 22, 2003, 07:38 PM

yes,

there are many people that are running it great at a 166fsb... I can get it to 150 now with my system... But the memory timings have to be REALLY slow and it still will crap out within a couple minutes.

So then heres the question.

Im thinking about running my proc at a 150fsb.... seeing as though this puts my AGP bus at a 60mhz, instead of a overclock. BUT! Do you think my ti 4200 would have a problem running at a faster Bus speed? Like say if I were to kick it to 147fsb instead? ... (effective 73.5mhz agp bus with the system at 147fsb)

the reason I ask is: I want to see what memory I need to buy, I know 2700 runs 166fsb... But If Im overclocking my board to a close 150, would I still be able to get the timings I want? Or should I get some 3200 and be completly safe with the speed and timing?

I want to run no more than 150fsb (300ddr) and or 147.

(147 for the overclocked agp bus, the speed is WAY noticable with the overclocked AGP bus, but my worry would be if the card would handle it?)

now I know what Im typing isnt making much sense... ... if you have any questions, please ask.... I just need to know a good type of stable "FAST" memory to buy... that is rated faster than my 2100... thanks.

oh, and I also was wondering if I should buy ONE stick of ram... (I want 512) Or two sticks of 256?

Which would be better?

Anyhoo, Lookin like ddr 3000 is a good bet... what do you think?

Peace,

Vampyromaniac · Feb 23, 2003, 06:21 AM

I think as long as you get good-quality RAM (eg Corsair), I'm pretty sure that PC2700 would be enough for a 150MHz memory bus with aggressive timings. If in doubt, sure go for the faster RAM . . . couldn't hurt if it doesn't cost too much more

I really don't think it's a good idea to run your vid card at 73.5MHz AGP speed

I'd always keep it in the 60's.
So if the 147 FSB gives 73 AGP, definitely go with 150 FSB.

I think 1 stick of RAM is preferable. But it really doesn't make a whole lot of difference.

ToshiroOC · Feb 23, 2003, 06:50 AM

Don't get OCZ memory though - I have some, and if you use CAS2, you can't get anywhere near the claimed speeds, but have to use the absolute worst timings possible to get anywhere above 100fsb...

Madgoat1979 · Feb 23, 2003, 05:38 PM

im thinking I wanna get "ONE" stick of ram .(with 512) ... So I can get up to 1gig latter.

But I was searching around, and I found a stick of ....512 samsung 2700 ram for $65...... ................Is this good?

Im thinkin this will be the route I'll go.

anymore thoughts on to what I could do?

thanks guys.... OH and so you think running 166fsb RAM at 150fsb would be enough of a buffer to hit some good ram timings? Thats only 16mhz ..... (Im sure you guys would know better)

ok thanks Guys!

(oh and I've heard all kinds of stuff about OCZ mem, I wont touch it with a stick)

Peace,

If pushing the FSB is your goal, corsair XMS or kingston hyper-x is usually your best bet. I currently am running 1 gig of crucial pc2100 @ 147mhz. Most corsiar pc2100 can get close to ddr266.

I see many people buying corsaor xms pc2700 and hitting 180 FSB and higher. Coarsair is deffinatley a FSB overclockers dream.

shuki · Mar 17, 2003, 09:50 AM

If you're buying ram, the only real choice for the best bang for the buck is kingston hyperX from newegg.com!! Only $77 for 256MB and like $155 for a single 512 stick!! I bought 2x256 and am running 175fsb with absolute lowest, most aggressive timings in all my BIOS settings. 2-2-5-2-2-1T. Go with the hyperX!!

Funkybuffalo · Apr 22, 2003, 07:56 AM

From my experiences with a K7S5A, I would go with 1 stick of ram. I think they have some issues with 2 sticks from time to time, so better safe than sorry. I have had my system running at 150 before, but toned it back down because of the noise involed in cooling (i live in the south, kinda warm). For my system, it ran more stable whenever I disabled the Autodetect DIMM/PCI clock option (even though that would save power..hmmm), but I could never get real agressive with the memory timing w/ OCZ PC2700 RAM. If you don't already know about this site, go to www.ocworkbench.com and check out their ECS forum. It is definatly the best K7S5A resouce out there. They have overclocking bios and tons of knowledge. I always use the latest CheepoBIOS.

Funkybuffalo · Apr 22, 2003, 08:03 AM

OH, MAN. Don't know how I was looking at a thread that old. Sorry to bring it back up. I thought I saw the date as recent......my bad. ahhhh 2-21 not 4-21!

I've heard some good things about Corsair's Low Latency series of memory. You should check them out.

Hornizuka · May 1, 2003, 09:20 AM

I don't think u can goto 150FSB. Your MB is the problem. It will held you back. If you want to go for 150FSB, you need a new MB.

Wiz4rd- · May 1, 2003, 10:59 PM

Name brand memory is for the overclocking enthusiest. Save yourself some time and buy some cheaper winbond pc3500 chips @ a fraction of the cost and run them at spec speed. Why people spend tons of money on corsair pc3200 just to squeeze a few more mhz out of it when they could buy cheaper pc3500 and run it at that same speed the PC3200 corsair would. I jsut bought 2 sticks of pc3500 cas2 from hardcorecooling.us @ under $100 for each stick and it does 220 fsb stable with tight timings. I saved myself $120 bucks and got the same performance.

Kgentatszu] · May 3, 2003, 11:46 AM

guys, speaking of ram, in US or what so ever you are living in, have you heard of a brand named "APACER" ?? if so, what's the price like??
