Corsair PC4400 (2X1GB) Rocks!!!

[DAK1640]

This Corsair PC4400 is da bomb...I have used Crucial Ballistix (till it died), GSkill HZ, OCZ, and now this. I have yet to find it's upper end, but this is FANTASTIC stuff if you've got the deep pockets for it. A Few screenies...

[pcdoc1]

Won't it run at rated speed? I would think you'd be running 10 X 275 1:1...

EDIT: Sorry, I meant 10....

[DAK1640]

That's over 3Ghz...holy geez...I run too many other apps on my PC to run it that hard.

[pcdoc1]

Have you dropped the multiplier to see where to ram tops out? I'm looking for a 2GHz kit that will run 285 -290...

[DAK1640]

I have only tried what the screenies show, I am running 8 VM's for Dimes, Rosetta (2 instances), and playing Counter Strike. I don't want to kill my compy...It's blazingly fast at 2.6Ghz 2.5-3-2-6 @1T...I am happy;)

[creidiki]

PC4400 = DDR550, no?

Should be able to drop it in @ 275 mhz @ rated timings and off you go. If you cant, RMA it. :P

[n91htmare]

You should be able to get 160+ with that ram AT THE LEAST.. lower your multi and push that sucker...

[v0dka]

It's already been said but here it goes again: 275*10 1:1 ofcourse!

[Bootsy]

yes, lets see 275+ i am thinking about getting this ram.

[thunderstruck!]

It's DDR550 at 3-4-4-8 and is ~$275.:p:

[DAK1640]

OK, I'll do 275 x 10...I guess I need to change HTT to 3 then huh? I have only been running the ram at 1.65V, I did go upto 1.7V when I did 250x11 but just for a short bit.

[Deathspawner]

"I have only been running the ram at 1.65V, I did go upto 1.7V when I did 250x11"

I assume you mean CPU, and 1.7v is retardedly high for 2.75GHz. If you can do x10 multi, then I would love to know if you find these modules 3D stable at stock speeds. I have not been able to run games stable at stock speeds, but 272MHz is completely stable all around.

[DAK1640]

OK, I had them upto 280x9 and it did Pi2M no problem. This is really cutting into my Dimes running time...lol

Screenies for 275x10 as requested...That's all for this weekend. Very Fassst RAM indeed.

[creidiki]

Thats better! :D

Is it 3D stable?

[DAK1640]

OK, Imma noob...How do I check to see if it is 3D Stable?

[Deathspawner]

Open up MS Paint and draw a cube. If your computer crashes, it's not 3D Stable.

Seriously though, 3D Stable means game stable. Can you run any game reliably for more than 10 minutes at a time? I personally use UT2004 since it's incredibly sensitive to overclocking, and also HL2 because it stresses the CPU and ram quite a bit.

3D Mark 01 is also probably the best 3DM out there to check for 3D stability also.

[haste]

i just ordered one of these kits from zipzoomfly
$246 after $25 mail in rebate.
i havent been very satisfied with my g.skill 2gb hz so i am hoping for good results from the corsairs...

[Bootsy]

for 246 I might get a pair of these myself:)

[haste]

for 246 I might get a pair of these myself:)


the rebate ends today so u gotta hurry if u want it at that price...

[farksy]

Cherry Picked UCCC ram =D

Hmm ... looks like some good stuff you have there !

My new sig, that's hilarious :banana:

[haste]

These modules use Infineon Rev C chips...is that UCCC?

[pcdoc1]

My new sig, that's hilarious :banana:Very nice........ :)

That is a wicked price.

No.. UCCC is Samsung.

Still waiting for a 3D Stable report :)

[haste]

i should have my set by wednesday.
i'll give a report then also...

[DAK1640]

OK, I have no idea how to draw a cube in Paint. Am I pitiful? Any other way to QUICKLY check 3D Stability?

[toolboy]

OK, I have no idea how to draw a cube in Paint. Am I pitiful? Any other way to QUICKLY check 3D Stability?

The answer for question no.1 is pretty obvious...
No.2 - have U heard about progs called 3dmarks?:confused:

[DAK1640]

OK, I ran 3D03 without problems and SuperPi 2M, all ok...Now no more down time on Rosetta & Dimes...

[Deathspawner]

DAK1640,

If you could be ever so kind to run 3D Mark 01 I would really appreciate it. I am talking about stock ram speeds (2T, 275MHz, 3-4-4-8). If you want a quick download link to the program if you don't have it already, I can PM it to you.

I don't have problems with 03, but it's not as touchy to overclocking at 01 is.

Ram at 2T ? Stock settings? Why is it when I run 275 x 9.5 CPU-Z says ram at 261 ?

[ozzimark]

Ram at 2T ? Stock settings? Why is it when I run 275 x 9.5 CPU-Z says ram at 261 ?
because when you run 9.5 cpu multi, 1:1 sets the ram speed to cpu/10, for 2612.5mhz / 10 = around 261.2mhz ;)

[DAK1640]

Now that makes sense...Thank You.

I find that HTT = 4X is better than HTT = 3X even at higher FSB's...At least per Sandra SI Memory bench. Does that make sense?

250 @4X is > 275@3X

[ozzimark]

makes no sense at all cause i put a lot of work into proving that the HT link speed does exceptionally little for performance. :toast:

[DAK1640]

Most interesting article, thanks for sharing...I guess the answer then is on the Ram timings.

[Deathspawner]

Is your 4400+ not stable at 2.75GHz even on water cooling? Or is there another reason you don't use a 10x multi?

[bachus_anonym]

Looks good, DAK :toast:
Can you lower multiplier to 9 (If your CPU doesn't do ~2800MHz) and try to max it out in 3D (3DMark2001, perhaps) @ 5-2-3-3.0-1T? That 261Mhz is good, but I want to see more :D

[Slammin]

I'm still waiting for the Rocks!!! part to kick in too. :rolleyes:

Actually, sorry for that bit of sarcasm, but I went through two sets of these sticks and could not get either set to perform anywhere near advertised spec with 3-D stability.

It's always a bonus when you can push/tweak beyond spec, and I do love doing that, but it is a real downer when you cannot even reach spec.

[DAK1640]

Thanks my friend bachus_anonym. I can try it this weekend. I am busy with Rosetta & Dimes presently. I am trying to determine my max output. I think dimes updates hourly?

The reason I don't OC higher is cause this is my main rig, I do 238x11 at stock Vcore 2.5-3-3-7 @1T and I am happy. It will do 275 x 10 but I have to up the volts to 1.475; also have to change the timings to CAS 3. I don't see any memory bandwidth improvment per Sandra, so I say why bother.

Yes I have had it as high as 2.8Ghz (255 x 11) and I was able to run SuperPi 2M without issues. Again I had to have the Vcore at 1.4875 and I love this rig, don't want to hurt it. This Ram is AWESOME.

Sorry XS, I guess I am just a whimp...

[Slammin]

I think you would have been just as good to get lower latency ram, which could be had for much less $$$ since you really aren't utilizing PC4400 with your rig. That said, that ram is pretty flexible with timings and does do quite well with tight timings, but you have to use dividers, but at least that ram is flexible enough to leave you with that option.

Really though, Rocks!!! nor AWESOME come to mind for me when it comes to this ram.

[Slammin]

And, furthermore, unless, and so far as I've seen, nobody is able to run these sticks stable at their rated speed, I will interject my own experience with this ram, hopefully preventing someone from wasting money.

Nothing at all directed towards the OP since this ram does what he needs. In his case, this ram can most likely be tweaked some, but that is not the point.

I'm not that much of a newb, and considering that an expert (BA) cannot realize the stated potential of this ram, makes me pretty comfortable that this ram just plain old does not do what it SHOULD do, as stated.

Rocks!!! AWESOME.


NOT!!

[Deathspawner]

The reason I don't OC higher is cause this is my main rig, I do 238x11 at stock Vcore 2.5-3-3-7 @1T

So why exactly did you get this ram and why do you so strongly believe that it rocks? You haven't run any 3D stability programs at stock speeds; all you do is underclock it.. but you continue to brag this stuff up.

I will be receiving another kit shortly that Corsair tested on their rigs that proved 3D stable at stock speeds. I strongly believe this is an issue specifically with DFI boards. Everybody who has had issues with the memory at stock speeds, have had DFI boards. That's why I was hoping to see some 3D stability tests done at stock on DAK's ASUS ;)

[kraggy]

I have had my sticks for a few days and I got them to 288fsb with stock timings. I am using the "up divider" of 250 in the bios (5-4) and then setting my CPU frequency to 238 fsb. alas, I never did take a screenie of it cause I am still tweaking it. but I pegged 275fsb on the nose. My bios is set to 250 (5-4) with Cpu freq at 225 to get me these results.

Why the 250 divider? Because my FX-60 suffers from the low fsb issue just like Major's.

[Slammin]

Benchmarks are really cool, but to pay $300 for bragging rights that really don't equate to anything else you can realize in actual use is a little bit much for me.

I do appreciate the 2D benchmarks you can get with these though.

[NinjaWreck]

This is one of the most misleading thread titles I've ever seen here.

[Bootsy]

kraggy nice sandra scores. what is the low fsb issue with your FX60?
mine also seems to run better with the 250 divider?

[thunderstruck!]

I don't get those sandra scores with my gskill uccc running at 275+, weird.

[kraggy]

kraggy nice sandra scores. what is the low fsb issue with your FX60?
mine also seems to run better with the 250 divider?

It wont' do 1:1 OC'ing past 235.

The only way I can get high bandwidth is to do what you just mentioned. I start out with the 250 divider and then run the cpu frequency up to 230-235fsb to get my above score.

[haste]

i bought some of this ram unaware that corsair tests it at 275mhz with a 2t command rate. no where on their website does it say anything about this.
i want my money back. i currently have a thread going on their forum so i'll see how it plays out.

Yeah, I was kinda freaked out about that part too. But I am able to get it to 1T at the rated speed & timings. Have yuo tried it yet?

yeah, ive tried 1t at 270mhz and it fails at 3-4-4-8 timings.
fails on test #8 in memtest
2t works fine though.

[haste]

well. my memory is working fine now at 269mhz 3-4-4-8 1t command rate.
all i did was switch to the black slots on my a8n32-sli =/
i did a complete test with memtest and got no errors like i had been getting.
i will do some more tweaking in the coming days but im just happy its working right now!

[bachus_anonym]

I've been saying that in my 4400PRO testing thread and I will say that here as well :) Two things you should just stop worrying about with those sticks:

1. Forget about running it at its controversial rated 275MHz 8-4-4-3.0-2T already. Treat it like any other 2GB PC4000 kit based on Infineon CE-5/6 chips. Drop that idea of 2T and stick with 1T. Period! If it's not 3D stable at 275Mhz then don't go RMAing it just yet but look around the forums and read what Infineon CE-5 does on average, OK?

2. If your set does fully stable (including 3D) e.g. 265-270Mhz 8-4-4-3.0-1T then there is a 95% chance it will be same stable at much tighter latencies of 5-2-3-3.0-1T and same speed. Seeing people running it at loose 8-4-4-3.0-1T just makes me cry :fact: This is a low latency RAM not UCCC-type RAM, got it? :D

i just dropped it down to 3-3-3-6...
just testing it slowly 8)

[haste]

running it at 3-3-2-5 now, it passed a loop of memtest once before i left home.
i'm leaving memtest running until i get home from work.
what other memory do you think i could mess with? i tried changing the TRC to 14 but memtest failed. it seems to work at 17 so far. i have never really messed with a whole lot of memory timings before other than the main ones so this is new territory for me.

i'm using an A8n32-SLi Deluxe mobo
