NO offense.....

WELL PUT E!!!!!

Newegg doesn't always have the nest prices either....

But HERE is the 2x1 1800Mhz Crucial Kit. These ARE B.A.M.F. sticks!!! 2 sets is even equal to one set of the 1600Mhz kits...

Check it!

And HERE is the 2x2Gb 1600MHZ Crucial kit.... In Four different colors for you too!


These Will easily OC to 1750Mhz+

What are your sticks rated at? If they're rated for 1.9v I would imagine that they should be able to run @ 2.1v no problem depending on the IC's. My Patriots have D9GTS (AFAIK) IC's and they can take a beating.

But at any rate, when I was trying to stabilize my NB @ 2700 with my ram @ 1600 7-7-6-20-26-1T every 0.05v I upped the RAM it helped stabilize it longer. @ 2.05v it was stable for 8.5 hours, then locked up. Temps were great too, 48C on the NB. And just recently I figured out my XFi was the problem. For some reason the board doesn't play nicely with it and causes some games to lockup even at stock speeds. But I've been too busy to retest. Currently I'm running NB @ 2600, CPU @ 3600, RAM @1333 (7-7-6-20-26-1T).

Is it jsut me or does command rate not make any difference to stability? I've run @ 1T and 2T and didn't make a bit of difference.

Command rate dosent seem to make a difference that ive seen. I got the RAM i have (2x2 OCZ platinum 7-7-71.9v) to POST at CAS6 with 2.05v but windows dosent like it and gets a bluescreen after it boots. Are you only upping the DDR voltage what about any of the other DDR voltages?..just makes me nervous because 1.95 is in the red and 2.05 is way in the red.

I'm trying to get my RAM to run at 1600. I can do it with the memory at 1.65v, NB at 1.4v and HT at 1.5v. I was wondering is that voltage ok for the NB and HT? Its not in the red but close to it.

Also I can run 1600 at 9-9-9-24 2t with above mentioned voltage increases or 1333 at 7-7-7-24 1t at stock volts, which one would be better?

from my experince, it seems that Command Rate has a difference only when at the extreme opposite ends of the spectrum for the Ram Modules settings. So either very tight timings or very high frequency's.

As far as other DDR voltage settings... I found from my little bit of stability testing that there seems to be a sweet on the DDR-PHY voltage when running speeds of 1720Mhz+ at 1.25-1.28v It really has allowed me to become stable all the way up 1776-1780 Range.. But only for about 3-3.5 hours of Prime95 Blend...

SobePmp,

First, nice work on the 1600Mhz stable. Secondly, I would definitely try to work the HT voltage down. I know that it does have some affect on the stability of the NB I/O APLL (Analog Phase Lock Loop) but if you can, work that down some closer to the NB voltage... If you are not running the HT much higher than 2000Mhz, you shouldn't need to much over stock voltage of 1.2v...

As far as the timings and speed combos above, as long as you could run the 1600Mhz in conjunction with the CPU-NB up at 2600-2800Mhz I would try to get the 1600Mhz at CL8 with a mild voltage increase of the Dram. That wil help stablize the CPU-Nb being the Dram voltage acts a reserve/ backup voltage for the CPU-NB.

Others have experienced this effect as well.

Im just trying to get CAS6@1600 stable. What about the DDR Vref Voltage Mastiffman?

I've only upped the DDR voltage as that is theonly one that seems to affect anything. Upping the DDR Vref didn't make a bit of difference. As far as I can tell, that is only a reference voltage which allows different increments of voltage (0.025, 0.05, etc) rather than actually applying voltage to the CPU.

As for it "going in the red" I'm not sure if that's a motherboard limitation or is that MSI's way of saying "your RAM voltage is too high fool".

When you refer to "HT" do you mean HTT or HT link?

As for your RAM and timings, if you can run it @ DDR3 - 1600 then do that. At 1600 see if you can run 9-9-8-24-32-1T. Dropping that one the 1 tick will make your throughput on botht the RAM and CPU higher. I can post up some screen shots of my DDR3-1600 testing with various timings for you guys to look at and use as a reference if you so choose.

I'm just used to my good old 939's where command rate played a much larger role in the RAM overall speed, and at higher clocks, stability. With 939's 2T offered considerably more stability than 1T. However, with DDR I was able to achieve 2-2-2-5-1T timings .

And thanks for the tip on the DDR-PHY voltage. I'll mess around with it some when I get a chance and I'll see if I can get my RAM to POST at a higher frequency.

EDIT: I just had a thought, it would be nice if we could make a list with all the voltages and what they exactly do. I think that would benefit our OCing greatly.

You know, that's good question.

If you have CPU-NB running higher, like say 2600+ I would have the CPU-NB (V) @ 1.425v Dram (V) a good .15+ above stock volts and I would try 1.23-1.25(v) for the DDR-PHY. I've never really needed it with tighter timings. normally a bump in DRam(V) will do that...

On another note... Looking back on "the burnin process" and it's effect... Check out this dual core s939 toledo. Playing with it until my board gets back and I get my C3.

It's a 2.6Ghz right now with the Ram (pc3200 max standard) running at 475Mhz. I was stable at 2.585Ghz at 1.52(v). 235 x 11. When I bumped the BUs to 237 to yield 2.604ghz I couldn't get past 4 minutes on "core 0" everytime. I adjust the skew on channel A three different times and finally got it to Prime95 on Blend for 12 Minutes.

So I ran Blend again at the same settings agin and again and now it's still going...

reenforcing that burnin, in my eye's helps the CPU get use to running at the new frequency... Check it out... It's another 15 minutes past what it shows in the pic as write.

Black,

I don't think that you will get the board to post past 1710Mhz "Without" using the Multistep OC booster.... The max BUS MHz for the board seems to be @ 321Mhz from my records, which is 1 MHz higher than what HardwareZone.com could reach during their "Race for the AM3 Crown review" between Asus, Gigabyte and MSI...

Now, 321MHz is not the Max the board will do if one uses the Mulitstep OC Booster. There are two options un MOC Booster.
Step 1,
Which lowers your set BUS Mhz by 20mhz to boot into windws and after 30-45 seconds it raises the Mhz back up 20Mhz.

Step 2,
Lowers the Mhz by 40Mhz and once again, does the same as descibed above. but I haven't found that step to be very stable beig that a 40mhz jump is kind of like having EMI... LOCKUP!!!!
