Geil's new PC3200 Ultra X 2-2-2

[Sheik]

OK it is from another Anandtech review. And their reviews have produced some ... questionable results lately. But still have a look at this.
http://www.anandtech.com/memory/showdoc.aspx?i=2174


In fact, the highest speed we could achieve with Geil Ultra X, DDR561, sets a new record as the fastest speed yet achieved with a memory rated at DDR400. To be fair, DDR561 is a memory speed rarely achieved with any memory, let alone a memory rated at DDR400.

280.5 @ 2.85V 3-3-4-7 from DDR400 :eek:

Its based on Samsung chips as well.

Not to worry though.

Consider the A64 limit to be around DDR466 with this Geil Ultra X. That means for Athlon 64 systems, your best choices are still Crucial Ballistix or other Micron-based memory like OCZ 3500EB or 3700EB. The Micron-chip memory performs the same in our tests on either Intel or Athlon 64. If you prefer Samsung chips for your A64, then OCZ PC3200 Platinum Rev. 2 was the only Samsung dimm to reach DDR500, which was still far short of the DDR557 it reached on the Intel 875 platform.

is it an ondie controller thing? could be why I cant get my bh5 past 240fsb, is there a way to get higher? How am some of you guys hitting like 260-270?

[LorD_Kvadd]

Looks like som good memory... But I have bad expiriences from GEIL mems... Acctually I have bad expiriences from all mems I've ever used :(

its very simple.. You need to vmod, go boosterlistic or get a motherboard which has higher vdimm option..

[mcnbns]

I don't know why Anandtech insists on using tiny amounts of voltage to test the max speed of RAM. Surely they could at least go up to GEIL's rated spec of 2.95 max? Then they might be able to use some better timings for the high speed tests. :stick:

yes sir :D so I am assuming more volts also causes the ondie memory controller to overclock higher as well? If not then what good would it be if I throw in ram capable of 260fsb for example if the memory controller can only take 240MHz anyway?

[bias_hjorth]

I highly doubt the memory controller only takes 240htt. never heard any a64 board nforce board doing that bad.. most do 300htt+
And yes you could easily throw in some high clocking memory.. the onboard controller wont slow you dont :)

[thephenom]

I don't know anandtech keeps on talking about 2-2-2-5 at DDR400, quite honestly, I wanna see what the TCCD can do if you pump 3+v into it.

[Tony]

TCCD does NOT respond to voltage like Winbond or Micron does due to the small fab process.Smaller die=less voltgae tolerant.

[mcnbns]

Cool. Thanks Bigtoe. I learned something today. :)

[bh2k]

You know the saying mcnbns. ;)

[wfarid]

has anyone tested the Geil PC3200 Ultra X and see whether anandtech was right about the performance ?

[flapperhead]

nice ram..

[Kunaak]

I've had great experiences with Geils PC4000 and 4200 ram.
they do make some great ram if you ask me.
that mirror finish that comes on the 4400 ram is cool as hell if you ask me.

I'd be stoked to get some low cas ram from geil.
I think it would do pretty good.

running 7.5x320, ram @240 (bh-5), almost stock voltage (1.61). OCZ ram booster to go in today (been looking at it for two weeks now) as the max vdimm i can get is 3.44 (3.3 maxed via pot to 3.6). gonna make this BH-5 stuffs run with some insane voltage above 3.4...........

adding more volts via the 3.3 only adds addtional volts to the memory, NOT the memory controller on the CPU (vcore is responsible for that).

come on Tbird, you have been cruising with your a64 setup for awhile now, but you are now lagging with the overclockin' knowledge, wuts up with that???, there are tons of posts all over the place wtih great clues on how to max the clockage possibilities..................................... .....

anyway, back on subject, when the next wave of good a64 luving ram comes out, my wagon is pulling up to the back door and loading up...............these cpu's scream with the FSB.............as if i had to tell anyone that..............

It has nothing to do with the ondie memcontroller.
Here's some BH-5 (2x256) @261MHz with3.3V:

[Geforce4ti4200]

this is strange cause with command rate to t1 I cant get over 240MHz on the ram(yes I can get over 300fsb with ram async) but ram cant do over 240MHz unless I use t2 but this cancels out performance :mad:

It's probably because you aren't giving it more than 2.88v. :rolleyes:

I guess you checked his sig. GfTI4200 is consistant from day to day, he never lets me down with his posts.

[eshbach]

you mean bh5 needs voltage to get high fsb :confused:

[Nimrod0031]

I have had some of the OCZ ddr400 rev2 for about a week now and i have managed to hit ddr560....280fsb 1:1 but havn't really tested it further. I'm not sure what kinda voltage these things can take. I have only given it 2.9v so far. I'm scared to go over 3v right away.

[Geforce4ti4200]

if volts were the problem, why does using t2 command rate gain me 5fsb on my bh5 and 10fsb on my corsair value? changing any other timings does squat, just command rate. on my old 2800+ a64 I didnt have this problem, I could hit 250fsb out of the box with corsair value!

[bias_hjorth]

Running t2 command gains you nothing besides higher mem speed.. The performance is significantly slower than t1.. And almost every RAM flyes on t2 command..

[Madril]

How do this babies behave @ 2-2-2-11 1T ? Meaning ... @ what speed can u run stable with that timmings.

Thanks **

[Ubermann]

If they are the same as OCZ el rev 2 then:
Cas 2-2-2 = ~220
Cas 2.5-3-3 = ~280
Cas 2.5-4-3 = ~310

At 1T single stick.
If they are good ones.

[Crankster]

2 T stresses a lot less. Thats a fact, it's like driving your car on wet ground, the wheels spin faster but do less. It stresses the components less than 1T witch is like with slicks and Tracbite.

my bh5 does about 230 on 2.9v
and it does ~255 on 3.15v

so i definately think you just need some voltage.


on another note, my 3200 EL rev. 2 should be here in a few hours :)

[Geforce4ti4200]

how much of an increase would I need to get from 240ish to 260fsb with my bh5 if I can do like 245 at 2.88v? how high can the chaintech vnf3 feed? 3.1v max?

[blinky]

[Subsequence]

Mine does about the same but i didn't want to up the vmem that high and it doesn't play nice when working together coz it's DS 2x512.

[Nimrod0031]

I have only tested mine up to 220fsb 2-2-2-5
270fsb 2.5-3-3-10

Almost got into windows at 300fsb 1:1 just need to play with them some more.


All this was done on 2.85v

[Geforce4ti4200]

your BH does 245 @2.88v?, would say hella no, but i have some BH6 that did 240 @ 2.95v


maybe not memtest stable but my mobo goes up to 2.88v and I can run 3dmark2001 up to 245fsb at t2 command rate but t1 at 240 is faster anyway

[wfarid]

did anyone get this ram and test it out?

[blinky]

maybe not memtest stable but my mobo goes up to 2.88v and I can run 3dmark2001 up to 245fsb at t2 command rate but t1 at 240 is faster anywaymine did 240 3dmark stable 1T (CPU interface enable) @ 2.95v real, but it was single channel, 1x512. the bh6 i have now does 255 3dmark stable with 3.3v dual channel :)

[loonym]

Ok, sorry to get off the GF bashing topic. :p: I'm not really a bencher cause I don't have gobs of money to throw at my system but I do have these sticks. Tightest timings (CL1.5) good to about 210-212, cas2 to around 230 and 2.5 to maybe 270.

[wfarid]

so like no ram would be able to do like 280 to 300 t1?

[loonym]

They're always at 1T on my setup, I have no option to change it.

[wfarid]

does the asus p4c 800 e dlx always have 1t too?

[loonym]

I don't really know about that wfarid but the sticks really seem to get along well in my lp-ut 250 in spite of my crappy CO 3400+.
