Cheapest RAM that will allow 240FSB?

[imported_zenwhen]

I need something cheap and stable. I will be using it in an IS7 with my 3.0C.

Adata PC4000 from the egg or even better Kingston Value RAM from circut city or BB I forget which...$68 for 512 with rebate. You can look through the packages until you find one with Hynix BT-D43 chips, which are capable of 270MHz using 4-4-3. Just awesome and found on expensive PC4200 modules.

Zebo, you've used the Adata PC4000 ram before ? I can only get 220 on my 3.0c w/ hpx pc3500 .. prime95 gives me errors. also memtest fails past 225 .

Regards,
Jose

Geil ultra series 400mz. $125 for 512megs last i checked,mines pulls 250@ cas3 7-4-4, or 215 @ cas2.5 6-3-3.

you can pump 3 volts through it and thats still within its specs,so it has lots of room to grow.

I used it on a 2.4C, Well not adata brand name but adata chiped (hynixBT-D43) in Komusa PC4000. At the time it was only $120 for 2 x 256 and I had it running 250 MHZ 1:1 2.5-3-3-5 with measly 2.8 volts on abit IS7..unfortunatly thats all my chip not ram could give before I fried it or I'll still have it. (I'm used to high Vcores being an AMD/PIII guy...little did I know 1.75 was a bad idea)


This ram can run over 300Mhz and 270-280 Easy from what I've seen in various forums.Link and link

Edit It appears to be a moot point now since newegg only has the 256's left and is OOS in 512

Thanks Zebo, I'll keep an lookout for the adata pc4000 ram. I'd like to hit 3.7Ghz

NP good luck to ya.

KomUSA is very expensive right now @ $260 for 2x512. If you decide to get it don't orget to select "adata" from the drop down menu which adds $10 or you could get anything.

1:1 with lousy timings is no faster than 5:4 with good timings. It is often slower. Why pay extra for reduced performance?

I'd like to see some matrix. Heard above 260 it takes over 2-2-2 @ 200-210. Thugs did some testing and it seems to jive with this. more data needed.

 

[oldfart]

Its been tested tons of times by many people including myself. You dont gain any performance with the high latency, high DDR speed ram. Again, it is often slower. In real world apps, the performance difference one Vs the other is very small. Not worth spending the extra money on.

 

[Zebo]

Good high speed 4200 and good low latency 3200/3500 run about the same price. Can't even get Bh-5 anymore and if you can it's more, used. So I'm not sure what you mean but it's not worth spending xtra on?

But more along the lines I'd like to see a matrix with all platorms, p4, AXP, A64 plotting FSB vs. LL.



Found thread 252FSB wins 4/7 against LL BH-5 @5:4 252Fsb, natually @ 260 it would get uglier 270 more so and so on.

Thugs testing showed what mine and others have shown. No real difference unless you care about Aida and memtest scores. Real apps perform about the same unless you consider incredibly minute differences like

Aquamark3:
KHX = 51.59 fps
OCZ = 51.60 fps *

Quake3 Extreme: ~1280x1024
KHX = 204.0 fps
OCZ = 204.8 fps *

UT2003 Demo: ~1280x960
KHX = 212.3 / 100.8 fps *
OCZ = 212.3 / 100.2 fps

X-Isle Tech Demo: ~1280x1024
KHX = 150.3 fps *
OCZ = 149.6 fps

to be significant.

I haven't shopped for mem in awhile. The stuff is like pork bellies. It changes too much to keep up with. The point is dont go out of your way to spend a lot of $$ on one Vs the other. You can run 1:1 or 5:4 with similar performance. Get whatever costs less.

 

[Zebo]

True.

The thing is now, the high speed PC4000/4200 stuff can be had for $100-$130 for 512, while LL 2-2-2 3200 is an outragous $150 for 512 at it's in short supply only made by those smart enough to hoard BH-5 and BH-6 chips. Most name branded 2-2-3 3200 is well over $140 even. So this is why the Hynix/miron chipped high speed mem is getting popular as of late. Better price for more or less equal performance.

The good old days of winbond are gone unfortuatly welcome to bandwidth and crazy high timings

 

[oldfart]

Its a shame the good low latency ram is in short supply. There is some new 2-2-2 stuff out. I haven't used it or priced it out. I dont think it is quite as good as the BH5 of old.

Since P4 went DC DDR, the performance differences between different mem setups are not that big. Any DC DDR setup runs very well. It is not worth spending big $$ on high end ram. The performance gain/$$ is just too small. For a 240 Mhz FSB, you are looking at ~ DDR500 1:1 or ~ DDR 400 5:4. Get whatever wont break the bank and has decent timings if possible.

 

[maluckey]

Of course, everyone is forgetting that there IS BH-5 still available. It takes effort, there is still lots still on the shelf. I got 1gb of BH-5 for 225 dollars U.S. just a week ago. Most all KHX300/512 and KHX2700/512 are BH-5, and what's not BH-5 is BH-6. I got one BH-5 KHX2700 a year ago, and the 1GB of BH-5 from the 2 sticks of KHX300/512 just last week. Remember that Kingston remarks WinBond chips, so chips marked ****DW-50 are BH-5....ALWAYS.

DOH! Why didn't someone tell me this earlier! I'm going to have to hit up BB or CC...

Komusa Adata isn't terribly expensive. I bought Komusa Adata PC4000 256mb for $60 shipped, and I should receive it next week. I paid $55 for Adata PC4000 256mb from Newegg couple weeks ago but now it's like $68 there. I've tested Newegg Adata and it does 2-3-3-11 @ 200. Sure it's not 2-2-2-11 like my Buffalo PC3700 BH5 but that's not bad for PC4000 memory running at low 200fsb. Adata PC4000 or 4200 is cheap and will give me flexibility down the line with chip choices as it will run decent timings at 200 FSB and will run crazy high FSB at loose timings without extreme voltage.

That new 2-2-2 Samsung PC4000 is nice but at almost $200 for 512mb stick I think I'll stick with cheap Adata PC4000 and PC4200.

People have been posting about this at other sites for awhile. Anandtech is usually not the best site to get this kind of info. Much of the stuff here is just general tech.

 

[Megatomic]

I'd give you my Corsair XMS PC3500 C2PT (BH-5) for your current RAM (in the sig) and $150. It'll do what you want to do.
