Best ram for AMD platform

[chew*]

Hypers were best for deneb, thuban does better with psc.

It appears Llano is partial to psc as well........

I go strictly by measured/calculated performance.

Deneb hypers


Thuban PSC


Llano PSC


Llano should overtake both deneb and thuban easily if the cpu was at sub 4500.

[crazydiamond]

thuban psc need 2200mhz @ 797 and also +200mhz cpu-nb bump to be same as 1870mhz 666 hypers? i think hypers are hard to argue for thuban especially since thuban imc isnt guaranteed 2200mhz ram

i still want to see how hypers rip on llano with integrated gpu disabled

[crazydiamond]

My Kingston HyperX sticks with Hyper ICs are running very good with my Asus Crosshair V 990FX.

They're doing more than DDR3-1800 with CL6 timings easily^^

906 MHz @ 6-6-5-15 22 1t @ 1.73v - 32m



929 MHz @ 6-6-5-15 22 1t @ 1.76v - 1m

FANTASTIC results!! exactly what ram? have you tried any other hyper kits on that cpu?

Ahhh but you forget, Hypers on thuban lose 10 secs at same speed's run on deneb We've already been through this before.......

Same identical settings with hypers

Deneb 10:40 http://www.hwbot.org/submission/1028...in_40sec_422ms

Thuban 10:50 http://www.hwbot.org/submission/1026...in_50sec_281ms

Makes the 200 mhz NB difference a moot point.

10 secs can not be had from 200 mhz NB so in order for thuban to be matching deneb there is only one conclusion..........Thuban is faster with PSC.

As far as hypers on Llano at least on the UD4 they are not going to do what you think or wish they will do.

These are 2x2 GB Kingston HyperX 2000 CL8. SPD says they're from 04/10, so I think there are MGH-E on it!

The mainboard is just two weeks young so i didn't try a lot of but I also have tested my 2x2 GB G.Skill Perfect Storm 2200 CL8 and they ran very equal!

I think in the next weeks or maybe months i will post further results with my Elpida Hyper kits...

Basic stuff with Kingston:

735 MHz @ 5-5-5-15 22 1t @ 1.66v - 32m



765 MHz @ 5-5-5-15 22 1t @ 1.71v - 1m

[halofanman]

has anyone tried the G.Skill Flare 2000Mhz CL7 kits for amd? it was made specifically for the P2 x6.
I wanted to get this kit but new-egg is out of stock, can't find it anywhere else.

[Spcial]

They don't produce them any more i think, but they run very good on AMD.

stunned_guy from Hardwarluxx Germany tried them for benching and over 900 mhz 6-8-6 or 1000 mhz 7-9-7 were no problem.

I read through the first half of this thread and my eyes feel like dropping out of my sockets, so forgive me if this did get asked and answered :\

When buying kits online and not having the option to know certain things like production date, revision etc, how does a person know what IC they have? I'm looking at these kits and I personally am uncertain as to which they could even possibly posses
F3-12800CL6D-4GBPI

6-8-6-24 1.6V

F3-12800CL7D-4GBECO

7-8-7-24 1.35V

F3-12800CL6D-4GBXH (Ripjaws X w/ Black heatsink, I think = XH)

6-8-6-24 1.5V

F3-12800CL6T-6GBPI

6-8-6-20 1.6V

F3-12800CL7D-4GBRM

7-8-7-24 1.6V

OCZ3RPR2000CL7LV4GK

7-9-7-30 1.65V

OCZ3RPR1600C6LV4GK

6-8-6-24 1.65V

The goal is to have a kit that (hopefully) will do 2000MHz with tighter timings still than most of the stuff on the market. Usage for the memory is for review systems (AMD) with Thuban currently, Llano in route, and Bulldozer when it's finally released. Which yes, I also realize the scarcity of PSC/Hyper equipped modules :\

Thanks!

PSC chips aren't rare, in fact all of the kits you listed are probably using PSC chips. If you want a kit that can do 1000MHz, buy a kit that is binned for 1000MHz, or you'll end up with a kit that can only do 1000MHz at very relaxed timings or higher voltage. Check some reviews and tests of the kits rated 800MHz 6-8-6, that's actually a mediocre bin for PSC, and binning is very important with those chips.

[Erklat]

tRCD = CL+2 is like modus operandi for PSC chips. If you want 2000 and tight timings you're best off with 2000 rated kit as Dan suggests, and then tighten the latencies yourself. With lower rated kit you probably won't get both especially for 24/7 stability.

Don_Dan is 100% correct, I picked up a Ripjaws X 1600 6-8-6 1.5v kit to try out on AMD...needs 1.6v to run 6-8-6 at 1600...or did it run 6-8-6 at all? ...
The kit doesn't do 2000 7-9-7 or 8-9-8 at all on AMD, tried up to 1.8v under 110CFM fan, not even boot for 7-9-7, 8-9-8 boots sometimes. 7-10-7 boots fine up to 2030 albeit 1.7v, 8-10-8 however goes all the way to IMC's limit.

Hypers are still usable...but no high freq.

I just traded a Hyper kit for 4GB of PIS 2133 7-10-7 1.65v...

Yea, I did find that out. I've been doing lots of reading and what I had found out at the time of my posting had given me the impression that PSC ICs of Hyper clocking caliber were also extinct. I did find out that isn't the case though and my Kingmax kit (2200 10-10-10) uses PSC also, but it was misbehaving and wouldn't do the advertised speeds for the owner of the site I edit for, so they aren't exactly a shining sample. Most I've been able to muster is 8-9-8 @ 1833. Not matter what I've tried, 1900 or 2000 won't go. Heavily playing around with Drive strengths did get me a few POSTs under 1900, but it wasn't long before it locked :\ I really appreciate the info though. I figured that capable of 6-8-6 @ 1600 1.6V still would've had the capability of higher speeds at reasonable timings, but it's good to know that isn't necessarily the case! Was about to nab a G.Skill Pi kit for $50 rated for 6-8-6-24 1600 @ 1.6, and there's a Ripjaws X (black heatsink) I could get as well with same specs but is 1.5V.

http://www.xtremesystems.org/forums/...-X6&highlight=

Yea, I tried to get the site owner to nab them back when released, but no dice Alas, it is virtually impossible of being found for sale anywhere, and the site I did find has them for a fair bit o' cash (for me at least) :S You selling either of yours, or I assume you've long since abandoned them huh? lol

[Erklat]

If you aren't after benching, I'd snag a nice 8gb for cheap and see how sheer quantity stomps a few mhz more or timings less in the dirt.

Yea, but the thing is, they are for benching. To a degree at least, as I'll be using them to do reviews for AMD Motherboards (Llano and Zambezi) :\ I'll have to do a search to try and find a comparison of module capacity performance gains, and hopefully it'll include modules of lesser latency, but it wouldn't necessarily have to be included. Unfortunately all I have are 1GB modules, so I could only compare 2x1GB vs 2x2GB.

[Erklat]

Okay, I missed it was benching stuff.

[Formula350]

Okay, I missed it was benching stuff.

That's quite alright I appreciate the info either way It brings up a valid point as well, since 8GB is really coming into the market. It will have to be considered for it's performance worth for the exact reason you indicated.

[FlanK3r]

Chew: have u time (or chance) try all three chips at the same clocks? Im curious, if Llano will be really better than Deneb/Thuban or not - at example 3990-4000 Mhz

2200 10-10-10 is not a stellar bin as well, although I'm surprised they're that bad. If you want to try one of the cheaper kits, go for it, but don't expect too much from them. You might find some lucky sticks especially on older kits, but if you want very good PSC ICs, check out G.Skill's 2133 7-10-7 or 2200 7-10-10 kits.

He has done that already, at those clocks with high memory frequency, Llano is faster than Thuban/Deneb in 32M.

[websmile]

In spite of the fact don_dan is right, like most of the time I´m surprised by the fact that it took so long before people realized OC-mems are extinguishing - by the way I would never trade in good hypers for PSC, even good PSC are no match for good BBSE, this would be different thing. If these high clocks I´ve seen on new 990 are read correct at timings is another question for me as AMD Noob, friend of mine tested highest ram divider on 990 Crosshair five and foung out that timings read 6-9-6 or 7-9-7 for example had all same bandwidth- testing on other plattform fact showed that timings were always 9-9-9 and the lower cas for example which was put in Bios and read by CPUZ and so on wasn´t really set

It depends on the platform...
On SB for example Hypers have huge compatibility problems and only some sticks run, not many sticks will bench 2133+ CL7-7-7 or 7-8-7 while high bin PSC might do 2200 7-9-7...the difference is not large, unless youre using GTX2 or something, that costs twice as much. I hear some of those dont even do well.

On AMD I can't even boot 2000 with Hypers, (though I validated DDR3-2133) however PSC hum right along up to 2060. 1800 6-6-6 gets beat or is very close to 2000+ at CL7...

[websmile]

As said, AMD is not my special case, but on SB I can tell that I have 24GB of Hypers that run flawless even on UD5 and Maximus4 Gene, I always have and had PSC, but htese were beaten easily by my BBSE, where even very good PSC had TRCD limit of 9 under 1100, which is normal, so that I could only run 7-10-7-27 above 1100 to BCLK-limit my BBSE on G.Skill 2133 C8 for example did 1150+ 7-9-7-24 easily at 1,65V. So I stay with the sentence that I wouldn´t trade hyper for PSC, but accept your better knowledge on AMD, there it might be different

I had contacted them last night about Flares (if they planned to resurrect the line with Llano and BD coming out), and if they did anything like Spire where they contact a reseller for sending out review samples (I found a Flare kit, but @ $168). Got back to me today saying the Flares are in real short supply, but they could supply the RipjawsX 2133 @ 9-10-9. Didn't want to at all sound picky or ungrateful, but mentioned seeing the Pi modules doing well with AMD, if there are any of them available. Yet, if they aren't then that's cool and the 9-10-9 would still work great to help find the limits on boards

The Kingmax indeed might not be an awesome bin, but that's also not too surprising. Their "Nano" tech used for the modules and cooling seems to work quite well. Sure, all I've got for comparison are old D9JNL OCZ Reapers (2GB 1600 7-7-7 1.9v) and some 1GB Nanya 1066 7-7-7 ECC modules, but the Kingmax run very cool even under extreme voltage (DIMM voltage on this board is higher than BIOS, oops! PSC likes 2V, right? lol Thankfully I wasn't running them long at that). TigerDirect has (till the end of today, Aug 31st) PNY XLR8 2x2GB 1600@8-8-8 for $19 after MIR, 2 kits per rebate. A friend is building an AM3 but wouldn't have funds for about a month, so I nabbed 2 kits of them heh I don't know what they run, I suspect Hynix? Either way though, they will get the job done for him. He's probably going to buy both from me, but I said I'd test all four together to make sure they'd run happily in 4x2GB (since I'm going to sell him my 890FX Deluxe3).

AMD likes PSC over D9JNL too.

[BeepBeep2]

Actually I believe D9JNL works quite okay on AMD and really well on Deneb...I know GTS fly on Deneb compared to psc. I can get 2000 CL9 on Thuban with GTS.
I can't believe JNL being rated at 1.9v though, most kits rated 1.9+ I thought are GTS/GTR...

As far as Pi modules working well with AMD? I wouldn't go for the 1600 C6...2000-2100 8-10-8 isn't all that impressive for PSC. It works, sure...
I've got some Pi 2133 C7-10-7 coming my way, I was wanting 2200 C7 Pi/Ripjaws but settled for that. actually the owner had 8GB but traded four to me for STT 2200 C8

If you can find them, I think the 2000 C8 dominators will do well on AMD...
