Best ram for AMD platform

[Ph0bLif3]

I just managed to run 8Gb Corsair Dominator GT 2000Mhz @ 2000Mhz with timings 8.8.8.24.2T on ASUS Crosshair IV Formula + Phenom II 1090T. Image is below.

But did 8Gb 2000Mhz give any performance boost on Phenom II 1090T @ 4Ghz? It was stable but no performance boost at all. As I mentioned a couple of posts back on this thread, I think the CPU needs to be in the 4.2Ghz+ region to even benefit from such high memory frequency. I will provide images of benchmarks and stats below of my current 24/7 OC. Same as in my sig.



And some more below. Notice CINEBENCH. See how I placed myself at top. I think this is because the new 6 core 1090T fully uses my 2x 4870x2 in CrossfireX without any bottleneck.

By the way...I will tell you all a little story while I was overclocking Phenom II 1090T. At first I tried it out with my old MSI 790FX-GD70 mobo and everything was going fine until it just shut down. I could no longer start computer at all. Something shorted out. Luckily I did have one spare 790FX-GD70 mobo as a reserve but even that one broke down on me @ 4.1Ghz with 1.48v. My reserve was a completely new one and never used. So I pulled out my mobo and started examine it more closely. I unscrewed the heatsinks on both of the mobo's and saw that on both boards the NB had been burnt. I came to the conclusion that the 790FX-GD70 did not have enough "Phase Power" to handle the CPU at 4.1Ghz with a HexaCore. With regular Phenom II 965 C3 there used be no problem with like 1.55v at 4-4.2Ghz. It simply overloaded and became too much. The new 1090T is rated 125w TDP but I think it is only max temperature that is still same @ 62C and not the voltage. Otherwise I can't explain my 1090T OC @ 4Ghz with 1.36v on Crosshair IV Formula. 4Ghz with 965 C3 used to be for me at 1.45v. It would seem like max volt with Thuban is only 1.4v as to Denebs 1.5v. Just telling everyone this so you'll be careful if you are running 790FX-GD70 with updated bios and using Phenom II 1090T that "if" you go over 4Ghz+ and 1.4v+ it might break the board. Depends on what type of cooling you have also ofcourse but on AIR or like H50 only and not custom loop, then it is not enough. Atleast not on GD70.

thanks for the heads up.. i will be getting a new mobo i guess i was planning on using this one for awhile but dont want to take any chances.

[Hondacity]

that is awesome phoblif3!!!

ddr3 for amd has improved

asus rog ftw

[Smartidiot89]

The problem with these frequencies are that you need your NB twice as high as the RAM-clock to take full advantage of it, so for people who uses 3000MHz NB 1500-1600MHz is a better choice... I can sure see the benefit of 2000Mhz RAM when running DICE/LN2 where you can OC the NB higher.

Hi !!! anybody used http://oc.adata.com.tw/1_product_det...id=AD32000XU2K I keep trying to hit 2000mhz or is it the CPU? so far...http://hwbot.org/community/submissio...r3_623.4_marks , I can't push the CPU until I'll finish the water cooling+TEC ; I've used different voltages NB, HT ,SB ,RAM ,not the CPU because of the temp ,weather in romania is kinda funny ,in the winter its -15 and in the summer is 43+ and rising

[mav2000]

Just started working on timings for a new kit, and probably something that has not been discussed here till date. Am down to 1600 7-7-6-15-16 1T on a CPU NB of 2600. So thats not bad at all for a set that costs this low. Am going to keep working on the timings for now and then work my way up for speed. But at these settings they are running quite well. Memtest passed as well.

Have heard they are samsung chips. Any ideas on how to take this forward will be great.

[crazydiamond]

6.7.6 @ 1600 possible w/ more vdimm?? or start upping htt & see how high you can get them stable w/ those timings. looking good so far if they passed memtest at those timings.

[mav2000]

6-7-6 not happening at 1.65V...will try upto 1.68V dont want to blow a brand new set of ram...lets see how it goes.

i had a set and to be honest it was
thankfully mine died and i was refunded

EDIT:
Removed wprime results since there was no change, with it being a CPU intencive bench.

eco!!

my eco running @860 CL7 8-7-24 1T & @800 CL7 8-7-22 1T

[G.Foyle]

GoodRAM PRO 2000 CL7 @ 1800 6-7-6-20 @ 4 sticks (2 per channel)
How's this for a memory setup this is 64-bit OS, tRFC 110 and proper NB speed


Voltage is ok, they are rated 1.7-1.9 V

[crazydiamond]

wow very impressive

[DEVIL K-ce]

G.Foyle

Tell me Your full settings for memory in bios, because when I put the same memory on 790XT-UD4P I cannot go to bios, always is freez and nothing more Vdimm @ 1.8v and more is the key, and high trfc ?

Thanks.

[G.Foyle]

Voltages and clocks you can see on the screenshot, timings are set to 6-7-6-20 tRFC 110 CR 1, rest on auto

[richierich]

For the G. Skill Eco, what tRFC should I put?

[Lastviking]

I´m testing my TR3X6G1866C7GT sticks today...have trouble to make them run 900mhz 6-6-6 is it impossible with this sticks or something?, or are my IMC not enogh good?

They can do 900mhz 6-7-6 @ 1.74v 3dmark2006 , super pi without any trouble..

955BE C3
Gigabyte 790FXTA-UD5


And also do they die easy with to much vdimm? safe is what with air + fan?

[BeepBeep2]

1.67 to 1.70v is moderately safe...1.68v max for 24/7?
1.73-ish for benching

And here are some links to kits for those in the US who can not afford Corsairs $250+ prices:

Have you got your sett yet and tested them? , i wonder if they do 1800 6-6-6.

[BeepBeep2]

Not yet. Still waiting on my board too, it will be at least a week before I get to test these. crazydiamond ordered some too so hopefully he gets to post some results.

[wez]

Kingston low voltage kit. Seem to do ok

[Zeus]

Nice pair wez! Seems like Hypers, what volts for that?

[wez]

Nice pair wez! Seems like Hypers, what volts for that?

1.75v for that screen, although the benefit of going above 1.66-1.7v is questionable atm, other than for tightening up sub timings.

[mav2000]

1.75 is a bit much...I guess for benching it may be fine..

[TheGreenFoX]

Do you know what they can do with 1,65v CAS6?
