Corsair ValueSelect 2GB kit @ DDR520 test

Hi guys...

Just wanted you to know about the new Corsair VS1GB400C3 modules.
Here they are, Samsung UCCC ICs, BrainPower D6800 PCB (only diffenrence from the B6U808 being the module's height):

http://www.xtremesystems.org/forums/...id=36688&stc=1

They are rated CAS 3, with default SPD settings of CAS 3, RAS to CAS 3, RAS Precharge 3, Min RAS Active 8 (in short: 3-3-3-8). Here's for some short OC tests. All below screenies are done using the Abit AN8 and a voltage of 2.8V (adjusted DDR Ref. Voltage to -30mV) + crappy Venice 3200+ (sorry, had nothing else on hand at the time of testing).

Memtest86+ #5 & #8 stable @ 260 MHz 3-4-3-7 1T (Read to Write Delay is 2) - notice the high bandwidth at only 2600 MHz (over 3500 MB/s):

SPI 32M stable:

CPU-Z Validation: here.

Forgot to mention: Memtest was done with Winnie 3200+ and SPI test with a Venice 3200+ (board having problems with reporting CPU temp in Winchester's case - causes shutdown when I stress the CPU, so I had to use Venice for the SPI test)...

I realy think it's a screaming result for a value memory... especialy if it can compete (frequency wise) with G.Skill's and OCZ's 2GB kits. :banana:

Nice find :up: were they under $300

They're around 280$ without VAT in my country - here

Are you sure they're 1GB modules (VS1GB400C3... not VS1GBKIT400C3 aka 2x VS512MB400C3)? AFAIK the 1GB kits are performing like they should... like normal value memory I mean. :)

Unfortunately the ValueSelect series cannot be identified by anything else other than it's model #... unlike the XMS where you have a "choice" of revision and lot #.

nice oc on value ram
can u give a try on 270 3-4-4-8 1T ^^
thx

I see...

I'll go ask some info about the avalability of these special modules... maybe they changed production lines... new stock at retailers doesn't necessarily mean new stock at Corsair. :D

These I got, just arrived yesterday. :)

guess2098: I'll give it a try given that I'll make some more time.

The Brainpower PCB seems to be the common denominator in all sticks now. My UCCC on non BP PCB won't even get to 230. Nice budget sticks you have there. :)

i just found out that
http://www.xtremesystems.org/forums/...id=36688&stc=1

the week is 525

the 525 uccc is the best oc week, most 525 can up to 270~275
other then 525, can not oc as high as 525......

Can someone tell me about this? => Corsair PC3200 2048Mo XMS Twinx (2x1024Mo)

DDDR Dual Channel XMS PC3200 (400mhz) 2x 1024Mo - Cas 3 (3-3-3-8-T1) @ 300€ .

Do they OC well?

wow. those are whats underneath my ocz pc4000 gold 2gb

Let us know where they are available. Would be really nice to get some value ram that uses UCCC + Brainpower PCB.

I'll be doing a thorough search of every retailer/distri in AU in the morning for these particular sticks, I am sure they will compliment my nice new X2 :clap:

Just picked up a stick of this memory from my local supplier in Hull, he got a new batch of 10 last wednesday.
Running at 230mhz cas3 4-4-7 2T at the moment at 2.7v , lowering to 4-3-7 means a bsod on windows booting. Still tweaking at the moment.
My chips were marked: Samsung 525, K4H510838C-UCCC.
Seems ok, just have to push them a bit harder.

Rob H

What MB, CPU... etc? :)

So these new batches are Samsung UCCC? That's pretty nice.

Using asrock K8-nforce3 250 motherboard, Sempron 2600+ 64 E6, 1 gig Corsair samsung valueram, Leadtek 6800Le and 2 200gig maxtor sata drives. Cpu happily runs at 310mhz FSB with ht at 3x, using my 2x PQI trubo pc3200 2-2-2-5 Samsung Tccd I can run 310mhz 1:1 at 2.7v but 512mb is not enough ram for BF2, so I am running the corsair instead, will look to get a second stick soon

Rob H

ah sweet......
time to figure out where to find these sticks in my country.

Man, if you find out let me know! :bounces:

I am now Superpi32m stable and 3dmark2001se stable at 244mhz 2.7v at cas3 4-4-8 1T.
I have the option of going to 2.8v with this mobo but i always got the best out of my Samsung TCCD at 2.7v, so I will keep pushing at this lower voltage for the time being.

Rob H

Now got a validated 250mhz ddr , just checking it for 3d stable now, passes superpi 32m.

250mhz (500mhz ddr) validated

Rob H

260mhz fsb validated link
Definately getting better, doesn't like tighter timings at this 2.7vdimm but is prime stable and superpi32m stable.

This is a sweet stick, now at 270mhz superpi stable. Going to do a bit of gaming to test it out.

270mhz (540mhz ddr) one hell of a sweet stick Of corsair value ram!!

Rob H

This is great results for value kit. I'll check if I find it in my country :)

280mhz seems to be the best this stick can do at 2.6v/2.7v. If i increase to 2.8v then my overclock drops to 255mhz!! So it looks as if this stick doesn't like too many volts!!.

Got a validation at 280, was running 285mhz but it was too flaky.

280mhz validation

Pretty good for value ram. Looks as if Samsung have got another winner with these UCCC chips.

Rob H

Will check local stores for these UCCC sticks

Wow... Nintek in Australia has them
http://www.nintek.com.au/x/scripts/p...idproduct=3042

Looks very impressive.

Why dont you buy some then we can see if they are REALLY the chips and PCB being talked about here

They have a direct linky to this page trying to sell this ram so if it is not as per what is shown here, with the 525 uccc + BP PCB then I wonder if they could be sued as some of ninteks previous selling practices have been err, well, lets say less than honest :fact: :nono:

Nintek have confirmed with me that they have week 525!
http://www.nintek.com.au/x/Scripts/p...idproduct=3042
They said they'll be uploading their own 525 pics soon and will be guaranteeing them.

For the OZstralians, here's my little search for them.

Looks like you have done a more thorough search than I J0hnB :)

I wonder when they will be uploading their own 525 pics ?????, their guarantee, going by past performances, are worthless :fact:, though I really would like to be proven wrong (which I highly doubt) with piccies showing the week 25 chips on brainpower PCB's, then for someone more daring (and trusting) than I to hand over their hard earned then get the actual same product we are talking about here :)

edit: After looking at the Patriot 2x1GB kits HERE its certainly harder to choose which kit to buy

The pics are up now.

A couple of piccies do not an order make :nono: :D

Especially when a supplier has a known serious credibility problem, not to mention morals, or more aptly, the lack of :)

results look good

has anyone tested on DFI NF4 rigs.....

Well you order them, and let us know how it goes. :p:

I don't get it. Why do these 2x1GB sets have such monster bandwidth w/ such high latencys? (3-4-3-7 / 260MHz / 3508MB/s)

vdimm?

Anyone found a US supplier? NewEgg has 1G sticks listed, but since they dont assure what CHIPS/ETC I wouldnt risk $220 on a lark with them.

But I'd luv to have a pair of these to mess with.

Only 2.7v, my stick doesn't seem to like 2.8v.
At 2.6v and 2.7v I can run upto 280mhz, 285mhz is very flakey.
If I use 2.8v, then my max overclock is 265mhz.

Seems this samsung doesn't like too many volts, so stick the boosters away lads.

Rob H

Anyone found a supplier in EU for week 525?
Scandinavia or Germany?

Monge

Has anyone confirmed if the UCCC on non-BP PCB week 25 can OC like this. I have found some UCCC on KVR but the price is a bit hi to just buy.

Might be worth a risk, as it is week 25 it should be as good modules as the Corsair, not sure how much pcb performance will affect the overclock. Going to get a second gig tomorrow. I hope he still has some sticks left!!

Here's your answer right here, on the previous page. :)

So I'm guessing the non-BP modules won't OC as well as these. But you never know... might be worth a try. BP modules usualy affect ~10 MHz when OCing 2x 512 MB setups. Maybe 2x 1 GB is totally different when it comes to OCing, so that BP realy makes a great difference. :)

I still have a few more MHz to squeeze out of these sticks, however 250MHz failed memtest86 in test 5... maybe abit more tweaking will get me there, but on these results alone I'm quite happy with there bang for buck performance.

I bought some value select mainly after reading this and another thread on vr-forums:
http://forums.overclockers.co.uk/sho...71#post6017871

Not tweaked it with timings, but I needed to bump it to 2.8v in bios to make it post reliably, at default 2.7v obviously wasnt posting all the time although when it did I could run memtest #5 and prime without error.

Thx for the tip Varzmaster! :toast:

yeah yeah very good
i shall buy dual kit corsair 1gx2

megatron: I actualy managed to squeze 275 MHz 3-4-4-8 1T on the Abit AN8 with the Corsair VS 2x 1GB UCCC modules. They're quite a bargain at that price.

BUT pay attention as Corsair is now using Infineon ICs (relabeled as VS) that are left ofer after the binning of the 3500LLPRO 2GB kits ICs... as they have very low yield ;)

The only Corsair memory with UCCC ICs is the 4000PT 2GB kit... at least for now.

I dont know my chip http://www.amtech-vn.com/attachment....tid=5534&stc=1

Update for my value select: with a bit of tweaking I managed a rock solid 255MHz :) these sticks will go to 270 ~ 275MHz for benchtesting but will not pass memtest86 @ 260MHz.... overall I'm quite happy with these results for such cheap ram!
