Hi-Perf @ Low $$ -> 2GB DDR500 Patriot PDC2G4000ELK (Samsung UCCC) OCing Report!!!

[bachus_anonym]

Hello to all of you guys still interested in seeing yet another DDR OCing Report! :toast:
This time I decided to go for a brand, that although is very well known, has not been seen too often here on XtremeSystems Forums - Patriot Memory, which is a division of PDP Systems, Inc based in Fremont, CA :clap:
The kit I will be lookiing is PDC2G4000ELK, which is 2GB DDR set built with Samsung UCCC. It has been announced about 3 months ago but I have not seen anyone really showing any results with it on our Forums. As usual, I have kindly asked for a retail sample that is not cherry-picked for the purpose of my presentation on XS. This is what I was told as an assurance, which is good enough for me :)This is just a kit from our stock right out of production. We do not pretest these before sending out to review sites as I believe it is not a good representation of our products

So, after this short introduction, let's get on with clokin'! But first, let snap few shots...

A plastic package it came in

Part1: How good it is @ 8-4-4-3.0-1T

SPi32M & 3DMark03 @ DDR560 8-4-4-3.0-1T, 308x10=3080Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/308x10=3080MHz_DDR560_844301T_SPi32M_3DM03.png)

3DMark2001 & 3DMark06 @ DDR560 8-4-4-3.0-1T, 308x10=3080Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/308x10=3080MHz_DDR560_844301T_3DM01_3DM06.png)

SP2004 LargeFFT 1024MB used @ DDR560 8-4-4-3.0-1T, 308x10=3080Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/308x10=3080MHz_DDR560_844301T_SP2004.png)

SPi32M & 3DMark03 @ DDR566 8-4-4-3.0-1T, 312x10=3120Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/312x10=3120MHz_DDR566_844301T_SPi32M_3DM03.png)

3DMark2001 & 3DM06 @ DDR566 8-4-4-3.0-1T, 312x10=3120Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/312x10=3120MHz_DDR566_844301T_3DM01_3DM06.png)

So, 280Mhz is what this kit is able to take any task one throws at it. That sits quite well where good UCCC is going and this particular kit can go a bit further as far as benchmarking goes. Meaning, that 283MHz was good for everything, including gaming in FarCry and F.E.A.R, but not SP2004 or Memtest for Windows. Very good results, If I had to say something about it.


Part2: How good it is @ 8-3-4-3.0-1T

SPi32M & 3DMark03 @ DDR556 8-3-4-3.0-1T, 306x10=3060Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/306x10=3060MHz_DDR556_834301T_SPi32M_3DM03.png)

3DMark2001 & 3DMark06 @ DDR556 8-3-4-3.0-1T, 306x10=3060Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/306x10=3060MHz_DDR556_834301T_3DM01_3DM06.png)

SP2004 LargeFFT 1024MB used @ DDR556 8-3-4-3.0-1T, 306x10=3060Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/306x10=3060MHz_DDR556_834301T_SP2004.png)

SPi32M & 3DMark03 @ DDR560 8-3-4-3.0-1T, 308x10=3080Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/308x10=3080MHz_DDR560_834301T_SPi32M_3DM03.png)

3DMark2001 & 3DM06 @ DDR560 8-3-4-3.0-1T, 308x10=3080Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/308x10=3080MHz_DDR560_834301T_3DM01_3DM06.png)

This is an interesting part. I managed to get those sticks fully stable at almost same memory clock as in above Part1, but with a TRP=3! Very nice surprise and I liked to see it. Tweakers will love that, although it will not make a lot of difference in real-world gaming. But for us, XS'ers every bit of performance matters, right? :D


Part3: How good it is @ 5-3-3-3.0-1T

SPi32M & 3DMark03 @ DDR500 5-3-3-3.0-1T, 300x10=3000Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/300x10=3000MHz_DDR500_533301T_SPi32M_3DM03.png)

3DMark2001 & 3DMark06 @ DDR500 5-3-3-3.0-1T, 300x10=3000Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/300x10=3000MHz_DDR500_533301T_3DM01_3DM06.png)

Well, one step down and we're hunting for highest MAX stable at 5-3-3-3.0-1T... And we found it at a round DDR500! Pretty cool, to be able to run a memory at it's advertised speed of DDR500, but with quite much tighter timmings :fact: Again, this result places PDC2G4000ELK up there - but was anyone surprised? :lol:


Part4: First conclusion

This OCing Report has not been finished just yet and I still have few tests to run. But from what I have seen during those last five days with this RAM, I can say that it deserves excellent marks. Plus, we know that UCCC is perfect for those on the budget, but yet not willing to sacrifice any performance. This kit can be found at Newegg at a great price of $135 after $55 MIR (http://www.newegg.com/Product/Product.asp?Item=N82E16820220084)! It's worth every penny :fact:


Update1: How about full stability @ 5-3-3-2.5-1T

SPi32M & 3DMark03 @ DDR490 5-3-3-2.5-1T, 294x10=2940Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/294x10=2940MHz_DDR490_533251T_SPi32M_3DM03.png)

3DMark2001 & 3DMark06 @ DDR490 5-3-3-2.5-1T, 294x10=2940Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/294x10=2940MHz_DDR490_533251T_3DM01_3DM06.png)

SP2004 LargeFFT 1024MB used @ DDR490 5-3-3-2.5-1T, 294x10=2940Mhz (http://www.clockmehigh.com/ddr/PDC2G4000ELK/294x10=2940MHz_DDR490_533251T_SP2004.png)

"Tightening" to CAS2.5 appeared to be as easy as going to BIOS and changing it :) I got DDR490 which is good for probably everything but DDR500 was not quite stable. I almost got it to pass SPi32M, though...

Stay tuned for more benches and thanks for reading!

[shuRe]

god dang it how can you push out so many great reviews!

looks like another great set of UCCC has been discovered, and at those stunning looks and price i think ill have a look :p:

[Cooper]

Nice sticks. Those surely cost every penny.

OT Jeez I love those close ups.
Bachus you surely know how to handle camera. :up:

[Deathspawner]

That is some hardcore performance for that price! Good to see UCCC is still kicking some serious ass :D

Those are some nifty spreaders also.

[georgekh]

WOW!!! amazing results for a 2GB set!!!

[mrkram]

some good old UCCC loving

[ZeroX]

great review as always bachus ;)

[wa77ss]

+1 Patriot :fact:

Nice review :)

[Eldonko]

Nice work once again Bachus :)

[irev210]

very cool, I just ordered this same memory the other day. It just arrived, so Ill play with it in my DFI expert.

For 135 A/R it was a bargin for UCCC.

update #1-

Seems to be working great at DDR560 right now @ 3-4-4-8


woohoo, we'll see how high I can go.

[bachus_anonym]

I'm glad you guys like it :toast: The more variety the better and bringing it to XB is what I want to do...
Yes, this set looks quite nice, that's true. I will have few more benches done today, including CAS2.5 results - just for kicks :)

@irev210
Very cool :up: Can you post few results here, once you're done playing? Can you include CPU-Z SPD Tab too? Thanks!

[wtkprol]

Nice! I might have to check out a pair of these. Wonder how 2.5 looks.

[bachus_anonym]

Nice! I might have to check out a pair of these. Wonder how 2.5 looks.Just added - Update1 @ 5-3-3-2.5-1T ;)

absolutely, just give me awhile to get things rolling, imma be tuning for awhile


any suggestions? Im on a DFI EXPERT with an opteron 170 running a 1:1 ratio

[Big B]

Do you know if this applies to the 1GB kits of PC4000ELK and PC3200ELK stuff?

[bachus_anonym]

Do you know if this applies to the 1GB kits of PC4000ELK and PC3200ELK stuff?Hmm... It seems like PDC1G4000ELK (http://www.patriotmemory.net/products/detailp.jsp?prodline=5&catid=1&prodgroupid=7&id=3&type=1) is also assembled with Samsung UCCC chips. It says on their webpage - "Available in high capacity up to 2GB dual channel paired kit". But I don't think that PC3200ELK is UCCC, though...

But I would rather have you check that at the source :fact:

[irev210]

So far, i am doing 280mhz @ 3-4-2-8

You were right bachus_anonym, just as easy as changing it.


Ive tested 3-4-4-8 with lots of 3D games and zero issues, this ram seems just _unreal_ for the price of 135. Probably the best investment i made.

I do miss my winbond 260 @ 2-2-2-5 high voltage sticks, but 1gb just doesnt do it for me anymore lol

[bachus_anonym]

That's sweet irev210 :up: Is that a typo or you're actually running them at 8-2-4-3.0-1T? I have to try that as well...

Anyone else around here with those? Come on, don't be shy people :D

[Bail_w]

Not on sale anymore :(

I was thinking the same thing :P howd that 2 squeeze in there :P

[irev210]

sorry, Typo!!!!

i ment 3-4-3-8 -1T

[farksy]

Nice ! =D. That's a great review ... should do more of this ! And this pair of rams is a steal @around 220 USD ... grab it while stocks last ! :D

[creidiki]

*whistle* nice stuff... too bad the only patriot sold in the uk is the drr2 kits :(

[irev210]

Hey bachus, what week is your samsung UCCC? Upon further inspection of my dimms, the heatspreaders suck. The Thermal tape maybe makes 20-30% contact with IC, some of them, the IC doesnt even touch the thermal tape... like a mini oven.

I carefully took off the heatspreaders and put them aside incase I need to RMA.

My samsung memory is week 552. I wonder if newer UCCC is better. Any thoughts?

Really wish I could get some higher speeds out of these.

[bachus_anonym]

@farksy & crediki,

I'm glad you guys liked my little write-up :)

I know there are Samsung original 2x1GB modules built with IC's weeks of 0601-0603, 0610 but I really have no idea If those are any better. From what we have seen, 280MHz 8-3-4-3.0-1T is very good UCCC so you should be fairly happy :)

[irev210]

bachus, ive spent a lot of time trying to squeeze 5 more mhz out of the memory, and it just isnt having it. I will go ahead and do my screen shots now that i know this is pretty much the limit.

I was able to do a 1m pi at 290 8-3-4-3-1T just once... but that was luck lol.

in about 35 minutes, ill have my 32m pi up

[-47-!]

;[ 200 on newegg now no MIR I wanted these suckas

Well i always thought that heatspreaders just hindered the overclockabiliy of your rams, as the contact and heat transfer isn't very efficient, even if lab tests from the ram manufacturers have proven otherwise.

Personally i can't take mine out as it's under warranty. [Parent's $$, so better not fool around with it.]

[bestmancajun]

Heat up the ramsinks with a heat gun and give it a squeeze.

[eva2000]

excellent work bachus... knowing how much longer it takes to test 2GB kits over 1GB kits, i appreciate your hard work :)

G.Skill - Personally used and its great! Had 270 @ 343
Patriot- tempted with the rebate

[macaddict]

I just went with the G.Skill HZ but if it doesn't work out I'll sell them and go with these Patriot's. They look really nice indeed.

[tommo123]

i've been trying to find RAM that can run in the yellow slots in my DFI NF4 mobo. crucial ballistix/G.skill etc. no joy. tried these patriots and they worked sweet. got them to 270mhz @ 2.5-3-3-7 and will leave them at that

love this RAM :D

[tommo123]

just noticed that OP got these to 2.5-3-3-5. wonder if mine will do too.

p.s, anyone with this RAM tried getting tighter timings than this? i.e 2.5-3-2-5 etc?

[azrael201]

Anyone have luck with this RAM...as much as the reviewer?

I know I know someone will point me to Praz's post but just hopeful for the right BIOS and settings. Interesting yellow slots are also good for this ram?

Suggestions?:confused:

I've tried orange and yellow slots and 704BTA and 0406 with the same stable 250MHz. There is not even enough headroom to tighten the timings.

[phi|os]

I just got some last week, and I'm already RMA them because the :banana::banana::banana::banana:ed up my windows install. The highest I could get those to boot was 245mhz, lol. I'll let ya know what happens when the next set comes in.

[breakfromyou]

wtf?! if it overclocks that well, why is it just being noticed?

i <3 patriot. right now im playing with my XBLK 1gb kit. right now im screwing around at 290x9, 2.5-3-3-7. its working alright so far haha. now wheres that guide that tells you about the more advanced memory timings...tRRD = !?

nice review. i was telling myself not to upgrade to 2gb until i get a DDR2 system. i think i just forgot about that...how well does the Patriot LLK 2x1gb overclock?

[azrael201]

Well me and another user, Playah believe that the chips were changed. In order to get the advertised 250MHZ you might need to crank up the voltage to 2.9V. Patriot forums said that should be the highest. Playah was only able to hit DDR500 after increasing to 2.9V.

We bought our ram around the same time him from the egg and me from zzfly. However, mine only needs 2.7V to hit 250Mhz. But it only maxes out on 260 using yellow slots.

[phi|os]

I got the RMA'd ram, and it's behaving just like the former. Can someone post up some timings (from the newer batch) cause the timings that bachus has up are just a no go. It just screwed up my windows config file, after booting up FOUR times. Can you believe that?

Just figured out that my board probably just isn't compatible with this RAM. Stupid picky DFI bull:banana::banana::banana::banana:.

[azrael201]

try 2.9V and stock 3-4-4-8 timing that is the advertised setting.

maybe if u keep RMA'ing you'll get the UCCC.

[KoHaN69]

My rig: dfi lanparty ultrad nf4, opty 148, ocz powerstream 520w, x1900xtx, PDC2G4000ELK

I got the same sticks phi|os was using.

I changed the timigns to 3-4-4-8, but didnt touch anything else.
I didnt change trc or anything.
it's been over a year since I overclocked memory, im gonna hav eto reread the definitive guide :rolleyes:

anyway. What's the stock voltage for 250Mhz 3-4-4-8 2.8v or 2.9v ? is the stock command per clock 1T or 2T ?
Is it better to use this ram in the yellow or orange slots of a Dfi Ultra-D nf4?

I got it to run @ 250, 3-4-4-8, 2.8v all tests ok except Half Life 2 (the ultimate memory stability program :p)



azrael201- your sig says
2x1GB Patriot PDC2G4000ELK (3-4-4-8 1T @ 2.7V 9/10 185Mhz)
DDR? 370MHz? fsb? or ur really doing low the low 185, 65MHz under the stock speed?

[KoHaN69]

Well, this thread seems dead :stick:

I RMAed the chip and got a replacement

The new pair do 265 @ 3-4-4-8 1T 2.9v, memtest86 and half-life2 lost coast stable

I know the general rule of yellow slots for UTT/BH & orange for TCCD, but does size of modules matter? what about these? they work seem to both :shrug:

:help:

:help:

Nice, good to see they worked out great for ya. I don't know about the ultra's slots, but 265 ain't to shabby. I think the best test for memory is dual spi 32M, and then a few hours of BF2 or BF2142, since EA really knows hows to screw :banana::banana::banana::banana: up, if you can survive an EA game, your stick could also probably survive a nuclear blast.

[KoHaN69]

Well, it was only 1 pass in Memtest, and I was playing gothic3 and it crashed, so i brought it down to 260, and i just had gothic3 crash again - must be the game :P
My results aren't nearly as great as Bachus though

I'll test it out throughly later. The reason I did Lost Coast is because (although EA is bad with memory too) valvE's and all source games are EXTREMELY depended on memory stability (even more than BF2)

What's the stock voltage? 2.9 or 2.8 ?

System:
Opteron 148
Dfi Lanparty Ultra D, rev b
2x 1gb PDC2G4000ELK
X1900xtx

Stability testing method: bios's MemTest86 1 pass, Half-Life 2 Lost coast, superpi 32m 1.5 xs

RESULTS SO FAR:

1:1 ratio
265 MHz @ 3-4-4-8 1T 2.8v

1:1 ratio
230 MHz @ 2.5-3-3-6 1T 2.8v

loosening timings to 2.5-4-4-8, or highering the voltage did not improve clocks


Current Testing config:

fsb: 330 MHz
cpu: 330 x9 (2.87 GHz)
ram: 330 * 7/10 ratio (231 MHz) at 2-3-3-6 1T 2.8v

-Why does CPU-Z report the memory to be 228.5 :confused:


-not too shabby, but i still doubt these are UCCC, if someone could tell me how to safely remove the heatspreaders to check the ram, that would be just super :thumbsup:

[halo112358]

What's the stock voltage? 2.9 or 2.8 ?
UCCC should be in the 2.6-2.8 range, I have some g.skill UCCC that I've played with a bit and voltage over ~2.75 doesn't seem to help much at all.

Is 7/10 ratio a DDR143 divider? If that's the case then your ram divider is 13, so you calculate ram speed like this

FSB * mult = ramFreq / divider

-> ramFreq = ( FSB * mult ) / divider
-> 330 * 9/13 =~ 228

:D go here (http://www.xtremesystems.org/forums/showpost.php?p=539462&postcount=7)

Here's what I'd do for UCCC, loosen the timings to 3.0-4-4-8 @ 2.7v and start them right around 250-255mhz - it should work like a champ. Make sure you read up on how the a64 memory controller handles dividers, it's a simple calculation but not the same as the 7/10 bios setting would lead you to believe. I had that same problem forever, it's much easier to OC on the a64 platform once you understand this.

[KoHaN69]

Thanks, appreciate it. Should I leave all the other timings on AUTO? I couldn't find a definite UCCC guide, and I'm not sure my chips even are UCCC

does running at memory speeds with remainders decrease performance?

thanks for the help halo112358


update: Although 260 1:1 was stable for Memtest86 and superpi, PCMARK2005 bsod-ed

I reread THE DEFINITIVE DFI A64 OVERCLOCKING GUIDE 's memory section (I know the forums are currently down, I grabbed a pdf from one of the members in the chatroom)

So I loosened the memory timings for pretty much everything, and it seems stable now, with PCAMRK 05 score of 4540

[halo112358]

Thanks, appreciate it. Should I leave all the other timings on AUTO? I couldn't find a definite UCCC guide, and I'm not sure my chips even are UCCC

I'm not sure about the other timings, they depend on the combination of your motherboard & your ram. I use an Abit AN8, it sounds like you use a DFI, so our settings are going to be different even though we both use UCCC.

Running your ram on a divider shouldn't decrease performance if it lets you run your cpu substantially faster :D You can test by running 1:1 with your fsb set to your highest stable ram speed (260) and benching then use a divider to push the cpu clock higher and bench again.

I bet you can get your UCCC stable at higher speeds, you just need to figure out what all the timings do and pick the right ones for your board & ram.

I just posted this (http://www.xtremesystems.org/forums/showpost.php?p=1965866&postcount=9) over on the g.skill board - I'm running my UCCC at 2.4v 265/1T 24/7 stable. The biggest thing that helped me was making sure I picked the right Tref for my ram (3120, aka 15.6us). I had to flash a modded bios to set Tref, then things were a lot easier. I think also that UCCC likes weak drive on DFI, I know it likes normal drive on the AN8 - weak drive crashes the machine on boot.

edit:

if you're sure it's UCCC go look at gskill technician's settings for F1-4000USU2-2GBHZ on your DFI board in the g.skill support forum, whatever settings he gives should work.

The new pair do 265 @ 3-4-4-8 1T 2.9v, memtest86 and half-life2 lost coast stable

I know the general rule of yellow slots for UTT/BH & orange for TCCD, but does size of modules matter? what about these? they work seem to both :shrug:

:help:

my sticks work the best in orange...they can boot in yellow but it causes my BF2 to crash after a while despite a 16hr prime stable test. There is no more crashes in BF2 after i switched to orange. it's probably because they are not UCCC's anymore.
