Best ram for AMD platform

[I.nfraR.ed]

Well, finally I managed to run my GTX2's at 1800 CL6. It was impossible with Crosshair III, now with M4A89GTD everything is ok.
Currently testing "on stand" with the box cooler and some helping 120mm fans, so I can't push the cpu really hard.

NB@2934MHz and RAM@1800 6-6-6-18-24 1T 90ns 1.65V SuperPi 32M



And some Everest with raised multiplier for fun



Everything on Windows 7 Ultimate x64
I'm gonna push it further on water when my parts arrive. So far, so good

[God_bg]

Very well, Infrared
890 chipset is good. And your new processor also

[I.nfraR.ed]

Actually it's my old cpu

I mean this in your signature

Not tested thoroughly, but it looks promising I was running it at 4.2 before the water setup cleaning, but I can't say it's Prime stable (only ~20 minutes).

You should be able to get the timings even tighter though, i've ran 6-6-5-16-24-1T last night with my dominator 2000CL8,
32M that is.

[I.nfraR.ed]

Yes, 6-6-5-17-22 1T was possible, too. This was a test only for the "rated" specs of the RAM, because I couldn't achieve it with Crosshair III. Otherwise it can do much more, no doubt

Anyone know anything about this kit?

http://www.newegg.com/Product/Produc...pk=ddr3%202000

Is it Elpida, Samsung based or Micron? Somethings tellings me Samsung.

2000 6-9-6-24. If only the tRCD was better and not so important.

I'd like to get some better ram for benching and use this OCZ in a 24/7 machine cause 1333 6-6-6 is perfect for that. I'm trying to avoid having to pay $250+ for Corsair. I saw alot of interesting kids @ cebit/ces but I haven't seen any of them hit the market yet.

EDIT: These too. http://www.newegg.com/Product/Produc...-322-_-Product

[I.nfraR.ed]

Someone tested the first kit, they are not for AMD, unfortunatelly. I was wondering about them and the Dominators, because of the price and was hoping to tighten the timings, but when I saw that test I went for the Dominators.

TheBlueChanell, best cheap kit for benching , by far, would be 2000 cl8 kingston hyperx with elpida mgh-e hypers

gskill pis are all powerchip, run high freq but with high latencies so in the end performance isn't good

[runnin17]

If you guys had a chance to get 6GB of this for $475, would you guys do it???

I will likely be picking up another 2GB for a complete 8GB, but I figure right now this is a decent price for it.

800$ for 8gb mem. if you think it is decent price, let it be

Ummm, doesn't really answer my question at all

[Zeus]

I.nfraR.ed, good to see you've got it steaming now, the sticks are expensive but awesome.

That chip of yours doesn't look too shabby either, that NB freq is not bad at all, especially on a boxed cooler. Is that a week 1001 chip?

[I.nfraR.ed]

Nope, this is my first C3, it's 0945DPAW. I think it's a high leakage chip, because I hardly make 4.1GHz Prime stable on water or it takes a big bump in voltage, but it scales nicely with more of it It has max stable NB of around 3050MHz, but since I was using the box cooler, I couldn't push it further. Wonder what it can do on ln2, lol. The 1001 chip is waiting on the shelf, it was running fine at 4.2 before I pull it off, but I didn't have the chance to test it good. We'll see if it scales with voltage, or not.

[Cele303]

What was the problem with Crosshair III and 1800mhz frequency? I love your memory, I'm thinking about switching from 1866C7 to GTX2, I can hardly wait for chew's stage 3

[I.nfraR.ed]

Instant memtest errors, I couldn't get it stable over 1700, no matter what I do - timings, voltage...It seems that something is very wrong with my particular board.
Additionally it's overvolting with at least 0.06V. I will get rid of it very soon. Nothing is overheating, the memory didn't run at desired speeds even with everything other on default with increased voltages. As you can see, they are running flawlessly on the other board with high NB and default voltage at 1800 CL6

[Tomasis]

Ummm, doesn't really answer my question at all

what do you mean with 3x2 gtx2? there is a kit for such? or i did misunderstod?

Hi my friend

My first question would be : which bios are you currently running on the Crosshair III ? My board came from the factory with 1301 which was released at the end of December. With that version I have had great success running OCZ's inexpensive AMD black Edition into the mid 1800's stably, and have booted into Windows in the low 1900's and benched (but not very stable @ 1900+). Overclocking is excellent on this bios also, as I'm running clocks on a 965BE between 4100 and 4200Mhz with a Corsair H50 without issue.

Now in saying that, I'm always game for trying different bios' and updated to the newest release 1503. Everything went downhill from there. I could not overclock stabily as high, and memory overclocks were non existent and unstable. I couldn't even get past 1700Mhz with the memory no matter the voltage applied.

So bottomline is: check bios versions and don't be afraid to try older versions to alleviate issues. Again, the 1301 is very good.

Best regards,

Randi

I don't think there is a kit, but the guy had 6GB of GTX2 and was selling it for $475. I have since bought the set from him and they are in the mail.

Seemed like a pretty decent deal since a 2GB GTX2 stick is now $250 a pop.
So I just bought three sticks for less than the price of two sticks brand new

I have tried all the versions out there, but without success with the memory overclock. I'm currently running 1301.

Randy,

I'm using bios 1003 on the Crosshair III Formula. I tried newer bios' but found that latency in Everest memory bench increased over bios 1003.

So back to 1003 it was for me. I think some internal chipset timings have been relaxed a little in the newer bios', probably allowing higher memory clocks.

Didn't see much difference in bandwidth between the several bios' i tried though.

Note that once over ~DDR1780 w/ tight timings, bandwidth barely increases anymore. Unless you've got plenty of CPU power.

[MrIcee]

Zeus my man

Thanks for the headsup on the bios'. I will have to give some of the earlier versions a try , such as the one that you are currently using. I'm playing catch-up to you guys with my R+D preparing to bench 3D again, much different setup than what I was used to on the old DFI NF4 boards indeed. Only been at it a couple of weeks

Just pulled a 224,000 plus on Aquamark @ only 4184 MHZ with a pair of Asus 5870's stock on air. I'm only on a Corsair H50 for now until I get my test bench equipped and set up. I'm within 2000 points of you in 2005 without much tweaking yet.(31K vs 33K).

My 965BE might be a dud as far as the CPU-NB is concerned, as on air I cannot get it over 2890Mhz without lockup issues or failure to boot. I understand they will scale under cold, which I'll be doing in the future with the modded Prommy, but I had hoped for at least 3000Mhz for useable bandwidth development on my current cooling. I have a killer watercooling setup I'll move to before the Prommy, so getting to and over 3000Mhz+ NB was certainly my hopes before going cold.

Anyways, thanks again...onwards and upwards !

Best regards,

Randi

PS: Crosshair IV Formula just arrived at my doorstep..woo-hoo !

[Zeus]

Randi,

Good to see you back in benching and nice to see you chose to go AMD, most ppl go Intel nowadays but with the upcoming Thuban some ppl might change their minds.

It's been a long time since i ran Aquamark, my believe is that it runs best under windows XP and since i'm on windows 7 i haven't given it much attention. After i reached my goal of 300K on my E8600 i haven't benched it again.

05 on the other hand is a nice bench for AMD/ATI but it's mostly about CPU power and a bit about memory/timings. Pretty sure you will slaugther my 33K score soon.

My 965BE C3 has a very weak CPU-NB too, the 955BE C3 i have now benches 3D at 3GHz but the cores don't clock as good as the cores of my 965.

Grats on the Crosshair IV my friends, i will be getting one for my birthday, at least that's what i asked my wife.

Oh, i think this topic was about best ram for AMD platform...sorry for ot ramblings.

I'll bring it back by saying the Dominator GT 6-6-6 kit that Dumo talked about earlier is the cats meow. I'm pulling quite similar numbers, despite my poor NB, with it.

With everyone clamoring Epilida over BBSE, you would think this was a BH5 vs TCCD thread from back in the day. TCCD clocked darn well on low volts compared to the BH5 and really made more since for the casual OCer. Speaking of the amateur OCer, does anyone here know of some lower priced 2x2gb kits that will not break the bank, but let you experiment from 1333 up to 1600 or 1800 with decent timings and volts (cas6 or 7 at 1333 and cas8 around 1800) and fit under the fans of most backward facing air coolers out there? It seems awful dam hard to find any RAM made for AMD much less RAM that will do advertised timings on AMD. I see the OCZ AMD BE RAM, but i have been burned by OCZ lately in DDR3 builds that i have done for customers (web surfing and word and games that IGP's tear em up). I know the platinum's that i have gotten have been bad and doing 2-3 RMA's to get a decent batch that failed soon after, i went with some Geil sticks at Cas6. Works like a champ in my Mom's computer and they were very well priced, though only 2x1gb. Unless Thuban manages to magically makes the higher speed DDR3 worth it, i dont see why a some nice timings at 1600 wouldnt be the thing to get. It is so hard to find decent reviews for RAM on AMD setups these days.
