So I guess it aint easy to remove the heatspreader and impossible to remove the leds.

These seem very nice 2x1 Gbs Kits, i allways loved corsair kits :toast:
Mine will be here today. I'll post results.
We use different thermal adhesive now, I wouldn't advise removing the heatspreaders from the Pros, you could pop an IC off fairly easily, especially on DDR2 modules, BGAs pop off even easier.Quote:

Still tweaking because I've only had these for a couple of hours. I did a quick run at 1:1 and got up to 281fsb 1T. Haven't tried, and probably won't try 2T. Aquamark3 scores went from 115K to 120K with this ram and the settings I'm currently using. So far, I'm a happy camper!
Here is some nice low latency lovin. I lost 1000 points in Aquamark with these settings though, so I'm going back to 2.5-3-3-7 and going to tighten those down now.
@Slammin,
I'm glad someone finally is sharing results with this new kit :up:
One word of advise If I may, though. Keep memory timmings as you show in your 2nd post's A64Tweaker) but switch to 3.0-3-2-7 and forget about 3.0-3-3-7 ;) Past ~255Mhz you might need to loosen to TRTW=3 and above ~265 you will very likely need to step down to TWTR=2 as well. But that depends on how good your 4400PRO is...
With this kit, you should be seeing at least 265MHz 7-2-3-3.0-1T (or as you write it, 3.0-3-2-7), fully stable including 3D. That's what I really hope for, that is :toast:
Thanks, BA! I'll give that a shot. Here is where I am right now and this shaved a second off SuperPi 1M (28 seconds now). Btw, these are bios loaded and not A64 tweaked in OS. I think this is the most versatile memory I've seen since my old G.Skill LE's. I'd swear this was TCCD!
By the way, tightening at CAS 2.5 seems to have had very little effect other than 1 second gain on SP 1M, and Aquamark3 scores remained at the 120K area so I will definitely give your settings a shot because it looks like I may need more bandwidth at this point.
Love this ram!
Can you add few "more demanding" benchmarks as you go further, please? SPi32M would be great and of course some 3D as well. Also, can you add MBM or SmartGuardian so we know what vdimm voltage you're on?
Keep your TREF @ 3684 (100MHz 1.95) or 3120 (200Mhz 15.6) and TRC=7 and TRFC=13/14 at all times. Infineon CE-5 does not really gain a lot in terms of higher OC, from relaxing TRC.
BA, thanks and I am able to get great response times with this ram. I still haven't looked to see what the absolute 1:1 ceiling is but I know it is less than 300 so most of what I've been testing has been with the 180 divider.
I am running into an issue that seems to be a limitation of the ram and that is that I cannot get any type of 3D stability once I pass 269fsb. I Just to make certain it wasn't an Opti/divider issue, I set it to 1:1 and I still fail 3D after 269 fsb. I've tried 2.6 - 2.8v, and even 2T and the result is the same.
Is there some setting I'm missing that might account for this?
Thanks!
Actually, I lose 3D stability right at 267fsb. Screen just freezes and a few seconds later I get a BSOD mentioning nvid.disp or something similar. I did try different vid drivers but nothing helped.
Also, when running rthdribl.exe I get some micro stutter and I'd never noticed this before, but I do also get it in games as well. I'm going to pop my HZ's back in to make sure, but I know this stutter wasn't there before, whatever is causing it, making any adjustments to the ram, including running as low as 250fsb does not seem to have any effect.
Not so sure about my purchase right now. Memory is dual prime stable, Windows Memtest stable, no errors at all. Even at 275, no errors.
Is 3D instability a known issue with the sticks?
Hehe, I take it that you have not read a lot into my testing :) It's not "an issue" with those particular sticks but Infineon IC in general. All brands experience that - Corsair, G.Skill, Mushkin, OCZ... When pushed to high frequencies - depending on the kit but most often it does not happen below 250MHz - this type of memory IC looses 3D stability for some reason. Nobody really knows why it happens but it does and we all got used to it. Some speculate that it has something to do with power draw in 3D mode but unless there is a way to ask Infineon engineers about it, we will not know :DQuote:

Well, the only thing I gained with these sticks is lower latency with decent fsb, which is what I was looking for, and they delivered in that area, and I would consider them a great upgrade if it were not for the stuttering. I get the stuttering regardless of speed settings. I guess this is so much more noticable for me since I use a 24" WS monitor and I play flight sims (at 1920x1200) more than anything else. The stuttering makes the ground appear to be 'swimming'. Really bad effect!
The nice things I can say about this ram is that is is extremely user friendly. Even a n00b like me can throw all kinds of settings at it and it just happily runs, assuming it does get into Windows. Translated: once into Windows, regardless of how I got there, I was never able to see MemTest errors, no matter how goofy my settings were!
Oh well, they are going back. I did read your review, and had great anticipation awaiting these sticks, with a hope that the time between your review, and release, was probably due to them ironing out the 3D stability issue. Wishful thinking I guess.
Oh well, my HZ 601's are back in, and I'll probably just leave well enough alone. My thought is that Corsair is going to probably take some heat over these sticks though. I can't imagine the grief folks are going to go through in trying to determine where this micro-stutter is coming from; "is it my video card, is it bad coding?" etc.
Then again, on smaller monitors, and especially with fps games, the stutter can easily go unnoticed. Still, I consider this a lesson learned.
Thanks again for your help!
Odd... I have just fired up rthdribl.exe and it even runs at higher frequency than I can actually bench 3DMarks or play games, which is 271Mhz. I'm at 274MHz now and going without any sign of stuttering at all - whether it's windowed or fullscreen :shrug:Quote:

I'm convinced that this is junk ram. I'm sending it back.
I'm sure I've not found the exact failure points with this ram regarding 3D stability, and as you can see, have no desire to.
I really, yes, really did expect to be running 1:1@275fsb in a fully operational mode with this ram. It does seem that these modules are just not capable of doing that. I'm sending them back.
I already know that I will have to run a divider (boy do I miss my ballistics, when they were working), but these XMX sticks looked promising with a 180 divider, per spec, but as it turns out, I still had to use the same 166 divider with the XMS as I have to use for my HZ's because of the 3D stability issue with the XMS. No problem! The XMS have much lower latency, and was a pretty good upgrade because my in-game fps did increase, but, that stuttering is definitely a deal breaker.
Does the fps in rthdribl.exe drop down like 20 fps every now and then? For me, it will be getting 125fps, drop to 90fps for 1 or two frams, and then back to 125fps. I see the same behaviour in games that have sensitive fps counters.
Anywho, already packed this ram up for refund. Definitely, FALSE ADVERTISEMENT, since even your review sticks still cannot do what they are supposed to be able to do.
don't know what your smoking dude, but he already posted 285 at the rated speeds... which is Above its advertised speeds :stick:Quote:

you might want to double check things, before calling someone a liar.
PC 4400 = 275 x 2 for 550 mhz.
his top posted shot... 285 at 1:1...
or DDR 580.... well above "what it's suppose to do" ;)
Oops!
Maybe I worded something wrong somewhere!
No way was I intending on calling someone a liar. My point is, these sticks, as fast as they may be, do not do what I expected/supposed them to do. Of course if they could be 3D stable above the advertised speed, I'd be way more than happy (unless they stuttered there too), but the fact is, they are only 3D stable way below their advertised speed. And they stutter no matter what!
Not tryiing to start anything. Hell, my 601 HZ's really suck compared to what the newer ones are doing, but, they do what they are supposed to do (and a little bit more) for what they are advertised to do, so I have no valid reason to return them, and will keep them.
Thanks, but I don't smoke.
@Slammin,
This is something that I think you should know... If you read my post #16 you would see that I sort of suggested Corsair to use PC4000 rating due to the nature of Infineon Rev.C (3D stability at high frequencies; 2T not helping solve it at all). Now, take a look at official release below and pay attention to so called "dual specification"...
I'm not justifying Corsair's decission here. I have always said, that this is a very nice product, with impressive performance. The only thing I was concerned with from the get-go was its high rating, which none of the other vendors dared to sell their Infineon Rev.C parts with :fact:
I just didn't do enough homework when purchasing this ram I guess. This ram is built for high OC benchmarks, but not for high OC 3D stability.
Granted, as I've observed, and stated, it is also some very flexible ram, which is really nice, but what does that all matter if you cannot do anything other than get high Sandra Memory benchmark with it?
I'm not convinced, at least from what I've seen that the rating of this ram is a factor. Even at PC3200 speeds, the stuttering is there, at least for me. There just seems to be some inherent flaw in the design if this IC. News flash? Was for me!
No biggie, newegg has been really good with me and I will be promptly returning this ram for refund.
You did point out the very flaw that I am seeing, though at a slightly higher clock than I see it, but again, and probably due to my monitor size and the res, and predominant type of games I play, the stuttering is definitely a show stopper for me, and it is noticible even at lower ram clocks and I cannot get rid of it with this ram.
I can say with confidence that I would not advise anyone with similar goals and equipment as mine to purchase this ram.
If benching is all I was interested in, I'd just throw my old G.Skill LE's in and post some really (relatively) impressive numbers, but my need for 2gig is almost strictly for gaming, so, I'm not really interested in synthetic benches in that perspective.
I hope I'm not unwelcome here, but I also hope I save someone else from tossing $300.00 in the wind.
TWINX2048-PC4400PRO is built with Infineon Rev.C that has been also used by other vendors on their 2GB - G.Skill (PC4000 2GBHV), Mushkin (PC4000 Redline XP), OCZ (EL PC4000 Platinum). It did not matter what brand you bought - they all behaved the same way. It's something people are getting used to and average one gets is somewhere around 265MHz, 5-2-3-3.0-1T, fully stable including 3D and games. There are some that can pull 270MHz+ as well. On the other hand, they are "desktop stable" often a lot higher, even into high 280'ies. You can find quite a few threads about it here ;) The set I have here passes 270Mhz at anything I throw at it - 1600x1200 gaming (FarCry, NFSMW, F.E.A.R, Doom3, Quake4, FIFA06, BF2...). No sign of any stuttering, screen freezing or going blank until I decide to go with 272MHz.
If you can't leave with a side effect of Infineon IC then I would think this type of RAM is not for you... If you're getting stuttering @ PC3200 then there has to be something else that causes that. It's simply unheard of to see this at such low speed with ANY of the Infineon CE-5/CE-6 kits.
The 3D BSOD's go away below 268fsb. The stuttering never goes away. It's really easy to see in LockOn. Matter of fact, when I enable the fps counter in LockOn, I can see it dropping 10 fps for about 1/2 second, then back to where it originally was, and this is on a static screen with nothing moving. I've got my HZ's back in now, and am not seeing this effect anymore.
I guess my system just doesn't like this particular IC so I'll be sure to stay clear from any ram that uses it.
thank you bachus_anonym...:banana:

very happy with purchase....no where the hell is that coolit system ;)
That's a good start :p: Come on, crank it man :D This RAM can do at least 265MHz 5-2-3-3.0-1T, fully stable...Quote:

Thanks :toast:
I'll provide some of those benchies as soon as mine get back from RMA. Hopefully this week.
I tried to do some benchmarking with mine today, but MemTest would freeze at stock settings (DDR550). Going to hook up a fan to blow on it to see if it helps. These modules get very warm without a fan though.
