Now with AM2 out and Conroe due in July, I think it's about time we started having a discussion and benches in terms of bandwidth for DDR2 modules. I've been searching around on the net and there hasn't been a properly collected DB of DDR2 overclocking.

Do share with us your results and screenies. Even if you're running it on P4

In order for a recognised database, please include links to CPU-Z's verification page for your rig and post screenshots of SiSoftware Sandra bandwidth test (Unbuffered)

Ranking will be done in terms of DRAM speeds obtained. Not processor clockspeeds or percentage of gain. However in the event of equal frequencies, I'd like a screenshot of bandwidth utilising preferably SiSoft's Sandra (Unbuffered)

Which DDR2 to get for overclocking?

Timings and rated Mhz are actually divided in 2 for general reference to DDR. It'll be easier to look at it that way. The advantage DDR2 has over DDR is that the bandwidth has increased significantly if clock to clock (For example DDR 400 Vs. DDR2 800)

thanks for posting but I had a look at it before this. It's just a list of possibly clockable modules but we need a proper database of proven clocks like those currently available for DDR's (e.g. screenshots, settings and stuff) like tone has posted. I wanna start gathering an OC'ed database

and thanks tone

This post has been edited by almostthere: Jun 8 2006, 12:31 PM

wouldja believe Corsair hit PC10,000 already, with DDR2 clocked all the way up to 1,200MHz? still in pre=pro though, but probably out in the next couple months.

True but with current limitations on chipsets, I'd wanna see benches on AM2 for bandwidth actually. TonyOCZ hit 7k unbuffered and 11.7k buffered in his Sandra benches already

where are the intel ddr2 guys?

kamon lah....

can i ask newbie question? ddr2 is hotter than ddr or not when oc? sry since that i still use ddr so i wanna make my new pc soon... thx..

Generally, no as DDR2 as per JEDEC specification works at a VDIMM of 1.8v wherelse DDR works at VDIMM of 2.6v. So in conclusion, DDR2 runs cooler comparably when OC'ed unless you plan to whack harder voltages then active cooling is recommended

from what i read, it's cooler compare to DDR

but i might be wrong as well if it only applies to certain ddr2 chip only

Anyway.... regarding the Micron's D9 chips...

from what I understand, D9 is just a code for Micron's DDR2 chips. the superior one was the 'fat body' D9 chips. but how does the normal D9 chips overclock (which are not fat body)?

This post has been edited by soulfly: Jun 14 2006, 01:21 PM

hermm.. so ddr2 is better than ddr meh?? i'll check later on my budget... hahaha

azrko, referral link is prohibited in signatures.

hence my intention to start a DDR2 database. To get as many feedback possible about all available DDR2's prefereably by chip

In terms of bandwidth, yes actually. Just don't expect very high DDR speeds. The highest known so far is 250Mhz

ADATA DDR2-800 512 x 2 Elpida GE-E chips @ 2.4 volt



i will post the mem b/w later

got something to ask here....

Does it mean that DDR2-800 will run at 400MHz FSB if no divider is used? meaning it is not only twice the frequency of the normal DDR400, but also twice the data rate per clock, since DDR2 is supposed to carry 2 times more data... which makes it 4 times more bandwidth compared to a DDR400?

if a system is running with both FSB and DRAM in synchronous, the memory will run four times the speed of the FSB (actual speed).

ex:

Intel 200MHz FSB (800MHz quad pumped) : DDR2-800 = 1:1

This post has been edited by soulfly: Jun 21 2006, 03:50 PM

for example, DDR2 PC6400 (DDR2-800)is supposed to run at 400MHz, so meaning if my FSB is overclocked to 400MHz, and with a 1:1 divider, the memory will also run at 400MHz, right?

Precisely if you're running 1:1 in terms of dividers. The added gain would come in terms of bandwidth as DDR2 will carry 4 bits of data per cycle compared to 2 bits on DDR

oi oi ..... Team Xtreem DDR2-667 <---- value for money... good overclocking!!!

i was wondering wat chipset does gskill memory use? im curious cz gskill seems cheaper thn any other ocz or team xtreem price...

On what rig laaa you're comparing dude?

So how? Mau include it in first?

Ok, will await then

My guess is Elpida's unless someone can prove it otherwise

Can also... but it's just single channel mode.

Gskill most likely using Elpida chips, or maybe Aeneon or any other 'value chips'.... only the 1GBHZ/2GBHZ are confirmed using Micron D9 chips (most probably D9GMH).

All latest results posted. Check first page for details.

pcmoddingmy and soulfly, do provide also details such as mobo and VDIMM to allow better cross referrals

posting edited : added mobo

wahlao..so nice rams..where did you get them?how much?you always get nice stuff ehh...hehe

reviewer always get nice stuffs

Added mobo info in my earlier post. VDIMM and other info is in the screenshot.

I got them from OCZ. I searched online for the pricing and it's currently for sale at above RM1.6K for a 2GB kit.

you got it for review purposes or you bought it from them?

Fankew pcmm and soulfly. All updated. Now we're getting somewhere

hey just a small idea...i think u guys shd put the timing in the listing as well

Will consider that but I prefer to concentrate later on the bandwidth obtained as it's pretty neck-to-neck between the 2 platforms and is a better evaluation of performance when overclocked

What I know is Corsair Value Select DDR2 can overclock at least one grade above stock without Altering the timing.My one is 512MB Value Select DDR2 533Mhz@4-4-4-12-16-1T which can up to 667Mhz@4-4-4-9-9-1T with 2.05V.It is not the max.So I don't understand why people intested in low latency RAM which cause few hundred ringgits more than that.In real world application,low latency only get 1-5% advantage.

any good oc chips in DDR2 value ram?
anyway to check?

elpida chip is good, but better if u can get micron.

normally elpida chip is marked with a 3 dot at the edge of the ram chip.

while micron is marked with single brown dot at one of the edge.

any code to recognize it?
any possible to get fatboy D9 in value ram?

fatbody D9 is no longer in production.. however the newer D9xxx are good as well.. though its hard to hunt for them in value rams...

Can share some pics for me to see the ram chip?

Ur bandwidth efficiency is 88-89%? That very high, mine is around 63-64% even my timing is tighter at 2T.
I guess it like S754, single channel give 90+% even on any timing at 1T.

no, especially nowadays fatbody is no more in production.

anyway... it's fatbody... not fatboy.

X2 will benefit DDR2 a lot. 10k in memory benchmark is so easy with X2 AM2.

probably DDR is a bottleneck for X2 S939.

some Elpida chip are quite good... like the 6E-E

but generally, Elpida can be considered moderately okay.

Micron square BGA are the current best. There are smaller rectangular type, but they don't do as well as the squares. 'Fatbody' is rectangular BGA, but the chip is big like DDR TSOP, but slightly wider.

They are Aeneon (a division of Infineon).

Still better to use Brand like Kingston.

Please justify your point.

Kingston is long time ignored by overclockers for your information.

I'm scouting for DDR2 667 2x1GB.

I saw Patriot CL5. Is this good RAM? It come with RAM sink.

Which brand confirm have Micron Square BGA?

One reseller told me she can get Kingston CL4. I'm doubting her. She's going to bring one to me soon. But not yet arrive. So I still doubt her

the new Kingston Value RAM DDR2-800 1GB have Micron on it. I think at Compuzone is RM600... expensive...lol! 512MB module will probably have different chips I guess.

forgot about the timing for that KVR

Mine i mistaken elpida for apacer chips..

My TeamXtreem already arrive... will do testing tonight

post ur result ~

Bagi spec's rig la. No point I see benches if I dunno what you're whacking

cepat2 lai2 can't wait to see what those babies can do since over at XS the benches are a bit too hard to believe

BTW updated the rankings

owh, I was at LYP the otehr day and I saw a few KVR's DDR2 533Mhz's which were using Micron chips. Might be tempting

This post has been edited by almostthere: Aug 15 2006, 07:08 PM

look for Hynix C4... they do great as well.

Yeah I saw those too for the DDR2 667Mhz sticks. all that I was talking about are of 1Gb density in case you guys didn't know

Confirm the dealer don't know nuts about CL. So I'm back to square one. Still scouting for 2x1GB DD2 667.

Where to find Hynix C4? What is the brand of the RAM?

My friend can source Micron brand RAM. Wondering what ram they use? Is it square BGA micron ram?

Hynix do it again??

sorry for not being able to do some testing for my TX-DDR2, I was at my friend's house(ddww) the whole night testing his Hynix (OEM) C4-based 2x1GB modules (they aren't dual channel kits). The RAM was rated at DDR533 CL4-4-4-12.

As was expected... it ran all the way up to DDR1060 with CL5-5-5-12 without any issue (tested with SuperPi 16M/32M) on Intel P4-630 and Gigabyte DS3 with 2.2Vdimm. We used 1:2 divider to push the RAM to the max.

Here are some screenies (sorry....did not capture 32M)


SuperPi 16M @ DDR2-1060 5-5-4-12 (2.2Vdimm)


*Please note that these are OEM Hynix DDR533 1GB modules, not Kingston/Corsair/Apacer or whatsoever.

Unless they're old stocks, most OEM Micron nowadays are using the smaller rectangular BGA which are actually less overclockable compare to the classic 'fatbody' Micron or the newer square BGA Micron. The good square ones are supposed to be 'premium' chips....so they're the least expected on OEM DDR533/667 Micron. Those Micron DDR2 on Lelong.com.my are just the normal ones.

This post has been edited by soulfly: Aug 16 2006, 01:37 AM

Yeah but with all KVR DDR2 667Mhz's being remarked, it's pretty hard to tell which from which unless someone can give a decent description of how each chip looks like

my mobo cannot use ddr800 divider.... so this is what i can do for now....

mobo : Tforce550
ram : 2x512MB TeamXtreem DDR2-667 CL3
divider used : ddr667
vdimm : 2.41v (vdimm pencil mod, measured with dmm)

Link : http://forum.lowyat.net/index.php?showtopic=313858

Sheesh, kinda makes this topic redundant already. I'd suggest this be closed. Your call since you're the mod

nah... the benchmark thread is strictly database, discussions will be done here

easier to manage

yahh, me agree too
go goo gooo firefly, ehh soulfly

I think I'll most probably get Patriot RAM 2x1GB DDR2 667. Do tell me if this decision is wrong. It does come with ramsink.

wrong....

unless it's LL or XBL series

I don't have money to buy such expensive RAM
So is signature line good enough? Do you know what RAM it use?

OMG, you pawned me in another thread....

not sure about the signature line.... but probably some 'mainstream' chips like normal Elpida, Nanya or something...

Try get good Kingston or Corsair la... at least you can see what chips they're using (not covered by heatspreader). Or if possible, look for Hynix C4 (oem, DDR533)... should be cheap enough. They clock great as well.

This post has been edited by soulfly: Aug 17 2006, 11:14 PM

Nothing better to do....

Just now I did an experiment on how Tras value affect memory bandwidth in AM2 K8 system. Surprisingly.... lower Tras doesn't mean better. The following values were taken from Memtest86+ bandwidth display.

AM2 memory divider : DDR667
CL-Trcd-Trp : 4-4-3
Tras : 5-18 (options accessible from Biostar TForce550 BIOS)



*Will do more updates and testing with other benchmark like SuperPi etc...

hrmm.. you might want to visit MyPC. they are selling Patriot LL version 667 1gx2 (grey ramsink) for only rm780. version 800 is around rm8xx. the best part is that it's Micron D9DQT. at least according to xtremesystems. as far as i know, CVR 1g per stick is already rm330. 2g = rm660. add another rm120 you get a dual channel Micron D9 performance ram. if you ask me, worth it.

i'm quite sure that the patriot shown above is the one selling in MyPC. PDC22G5300LLK 4-4-4. i was very tempted to buy it but malaysia pc enthusiast still can't seems to accept patriot. own a patriot before tccd xlbk version but had a hard time selling it. the only draw back that i didn't actually buy it yet is after considering the second hand value. for my experience with xblk? it rocks.

This post has been edited by Sanko: Aug 19 2006, 02:59 AM

Sorry but D9DQT can only be found in very old modules with RED heatspreaders. Newer ones had been replaced with either Elpida or the newer Micron (most of the time is Elpida).... or could be anything.

This post has been edited by soulfly: Aug 19 2006, 09:36 AM

then luckily i didn't buy. thanks for the information.

newer Micron should be quite good. the advantages of the fatbody is that they can run on 2ns on Trcd and Trp... but at such tight timing they wont go very high as the new D9s do.

hrmm... been to lowyat today to get refund of my fortron epsilon. after asking pczone, they are selling kingston ddrII hynix but only got 533 version. don't know whether it's C4 or not.

Do you think it is a good buy? Or should I get Patriot LL series instead? Help...will need to get it soon

I think not only Nanya. I would say the chips are random. Probably normal Elpida as well.

OMG. Then Patriot LL series are better buy? How about second hand value? Or warranty? If you, what you'll choose? THanks

off topic: it's 12v is only 15A. the version dinster selling is 18A. that's why

which value ram is more Reliable ??
