Best ram for AMD platform

[Mastiffman]

So how do you guys feel about the OCZ Flex EX C8 2000mhz 4Gb kit? Stock Votage is 2.0-2.05v I have had them as high as 2.4v. Still have them and they're running strong right now @ 1704Mhz C6.... With a 2982CPU-NB and 4.048ghz CPU.... Any thoughts?

EDIT: Yes, prime95 Blend stable. 6+ hours... So far

We do 1760+ 6-6-6 with 2x2g at 1.65v 24/7 prime stable. D9 great for benching but this stuff is far more versatile. D9 is also pulling no stability above 1800 with c6 while this stuff is breaking 1900 32m stable @ cas 6.

Thanks CHEW!

So this stuff is Not D9? It IS "This Stuff" which is "more versatile"? Or it IS "D9"? Sorry for the misunderstanding....

EDIT: So what do you think is holding me back my IMC. Need to lower the Freq a bit and could possibly push the ram a bit further?

Read that, so the picture that I posted is of Micron D9GTR, right? Gotcha....

Mind if ask a bit about Drive strengths? If I'm not technically OCing my Ram (2000 Rated) then Drive strengths can be raised? If the forementioned is correct, if I were trying to run a 1600 kit @ 1700 then I would lossen the Drive strengths. Is all of this accurate?

If so, then what are the most focused on Drive strengths? I've heard Data, Clk and DQS... What about ODT ohms adjustments?

Drives are dimm specific, not speed specific....memtest is your friend with all memory settings and options.......

Drives are not needed for 24/7 use.

So I should just leave those alone then...

Just for clairification (And thank you for being patient with me on this!), If I'm using the Dimm Slots furthest from the CPU socket on my MSI GD70 I may need to increase the drive strengthe for that Channel? Do the DRam ODT termination values play any part in stability?

So basically it just comes down to Memory IC and IMC Quality paired with Voltage and timings? IForgive me but I'm still on the newer side of this venture and just trying to understand as much as possible...

For 24/7 honestly the best approach is the KISS method keep it simple stupid and for 24/7 use you don't need uber timings.

Set the primaries and voltage and leave the rest alone. Whats holding back your IMC is your timings, most d9 with any shread of stability save 1m top out around 1720 with C6, need to drop to c7 for higher.

This thread is about the best ram is preety much that, not necessarily the most budget minded and in real world will net small gains but it is the best.

LOL- Regardless, I want URBER TIMINGS! Just like you!

What's wrong with that. I'm not going to go out there and try break some world record. I just want to KNOW for sure what settings are required for high speed low timings Ram clocking and what the settings do? I'm not affraid to Spend the money on Ram. I have this kit and I'm wnting to max it out. If I have to end purchasing Some Cosair DomGTX's then I will!

But for now I wanted to try and "Pick Your Brain" a tad and Continue to make things "Difficult" (I Don't like simple. It's no fun!) in my OC adventure...

Fair enough?

Problem is most people want to screw with stuff that they don't fully understand. You want to play with drives, thats fine but they are useless until the cpu see drastic changes, like -180 temps drastic and even then only worth gaining a couple mhz .

Anyways I'm more than happy to help on the 24/7 stable stuff. Run the corsairs at 1.68-1.70 volts with 6-6-6-18-24 and you will be happy.

Run your d9's at 7-7-7-15-11 and they will go alot further.

Benching is a competitive sport however and everyone has to drive there own rig.

Gotcha! Thanks brother! Good advice too!

Question. Does a higher Ht ref Clk play a factor in how well the system can handle Higher Ram freq's? Some, have implied this in other threads... And will one ram Strap/ Divider possibly work better with the Ram than another. Just trying to figure out if I should really be using the 1:4 Strap or trying the others out with higher HTRClk Freq's....
Why are they useless without LN2 or LHe? Just because things (the rest of the systems freq's) advance further therefore they become a factor?

[chew*]

If you freeze anything with "copper" distances change as the metal shrinks when cold, you need to compensate for these changes, even a resistors value can change at -180.

To give you an idea back in the 939 days drives played a role in getting around cold bugs or at least allowing to run a little colder.

IIRC GD70 works well with 1333 divider, however it's usually board/bios dependant.

It's funny you should happen to mention this... All BIOS (even beta) released for this board only allowed upto about 1680 -1697Mhz, no matter the settings. And it seems that ALL of the Officially realeased BIOS "Hoover it up!" if you catch my drift.

The Latest Beta BIOS, which has been out for a few weeks IIRC, has enabled me to boot (not just post) into OS at 1800Mhz+! Before I would ahve had to use the "Multistep OC Booster" option in windows. Which has 3 modes:

1.) Disabled
2.) Mode 1 which downclocks the HTRClk by 20Mhz or to 200 if 19 or < above the HTRefClk.
3.) Downclocks the HTRClk by 40Mhz or back to 200 if less than 40mhz above 200.

I would use mode 1 and it would enable me to have my Clocks back up 20mhz (HTRClk) after abuot 45 seconds of idling in the OS.

No need for that now. Another thing that I, among others, noticed with diff ver. of BIOS is that most users of the GD70 with BE processors installed Can't Cold Boot (Shut PC competely down and then pwoer up from the off state) with the CPU-NB multi set to x14 or more... BUT one version of the BIOS allows this (but only upto the x14 multi fro the CPU-NB) BIOS 1.51b. So that told me that it was a BIOS issue. Maybe with Coding...?

Anyway, Thanks for the tips thus far. Do you use the Dram Ref Voltage at all? I've noticed that it will allow lower Dram Voltage Operation... but I haven't really seen a patern with it yet. I'm mostly tuned and tested with it to get results.

My 2x2Gb OCZ 1800MHz kit (OCZ3P16004GK) seems to be doing ok with AMD. Was previously using it with my p45 setup.

Voltage is 1.94V

Unable to get my D9KPT to do 1600 at even as high as 1.7v, with severely high timings, I swapped out for this G.Skill ECO 1600 CL7 stuff. Works beautifully at 1600 7-8-7-24 @ 1.5v...haven't pushed it because I hate this GD70. Running the latest official BIOS, and just stick with raising/lowering multi's because this thing refuses to POST if i change anything else.

can somebody give me a hand at taming this POS board? ...or should i say beast? Not understanding this whole DDR3 subtiming thing only lets me read the SPD and make assumptions based around that, 1 timing at a time. It kind of works, but I know I could squeeze more out of this RAM (2000 CL7 on 1156 i7 at 1.6v), just now knowing what i'm doing in BIOS with it. I had to take a picture of the "XMP" section in BIOS and set timings manually. Auto = no post at 1600 even with 1.5v+

So are you guys thinking this is good ram albeit expensive worth the money CMG4GX3M2A1600C6?

If you are pushing an 965BE to 3.8 and above. Is this a good pairing?

[Mastiffman]

Hey Chew, were you able to get a decent Clock on the NB with the Ram that high at all?

Well not hard to hit 2900-3000 NB at 32C load temps when cold.

Mine was done on basic water, if 970 32m stable cas 6 ( as everest stability is useless) with 2900 NB is good at 50C then yes.

[crazydiamond]

just below the temps it shows cpu utilization 0%, 32c seems pretty standard for idle temps

Guess I didn't see that.

[Cele303]

This beta bios for MSI is awesome... I'm playing with memory and old big typhoon cooler, maybe I can break 1900 with motherboard outside computer case and some aggressive fans?

[chew*]

Might need water for a little more control.

The imc gets funky with varying temps which is why I didn't use phase.

I'd be curious to see how the PP is compared to ch III or m4a79, usually msi has been just "backing" off on performance to get higher clocks.

[Cele303]

Thanks for the tip

I've noticed that PP is not good, I think that final PP will be worse than my Giga and much worse than your Asus mobo's
