The NEO2 is a Rock!!!

[Duvie]

I got my new Gskill ram that is supposed to be able to run 2.5,3,3,7 at 550ddr...So far so good....

However one of the sticks is a bit more flakier....I have one stick that in single channel mode with 2.85v I was able to run at 625ddr cas 3,4,4,8 with 3dmark, superpi, and what not test. With possibly more left. Passes 3 passes of memtest....However with both of them in I can't get 580, cas 3 stable...amy be voltage needs...

HOwever when I first installed them one of the sticks when in the slot 1 would only beep and no post. Placed it in the 2nd slot and it was fine. However that stick will not run 600ddr in single channel. I also tried slots 3-4 and they are BAD!!!!! With the flakier stick in slot 3 i would get missing or corrupt windows file at bootup. Swap thembetween 3 -4 and fine, but not stable at 580 and BSOD pretty quick, slots 1-2 does not BSOD just prime and 3dmark errors........

580 would be 290 at 1:1 which I would run if it could be stable...some reason it is not....


That leads me to my current testing....

I can run 166 divider but at 294x9 my current running speed the ram speed was below 500ddr.....So I decided to try again (could't get anything above 311fsb with my geil sticks stable no matter the vcore, vimm, dividers, cas settings, etc.) at getting 310x8.5 to work.....and then so on...I though it was the board but that must not have been it....

8.5x310 with 166 divider 1.58v, 2.85vdimm cas 2.5,4,4,8.... prime passes for 2 hours, memtest 5 pass, all apps run no issues

8.5x310 = 2635ghz....I knew this was fine but would probably hit limit at 312 or so and had plenty of ram speed left....

decided to try 8x multiplier


8x325 = 2600mhz w/ 166 divider 1.58v, 2.85vdimm cas 2.5,4,4,8....prime pass for 3 hours, memtest 5 pass, all apps run no issues


Pic!!


8x330 = 2640mhz w/ 166 divider 1.58v, 2.85vdimm cas 2.5,4,4,8....prime running 1 hour so far....all apps ran fine so far...


Pic 2!!

Anybody have an idea what 325 and 330 make with a 166 divider??? Bios says 270 for 540ddr at 325 and 275 for 550ddr at 330fsb.....

It might not be one bad stick, instead just the board not being able to go as high in dual channel.

Not to piss on an awesome overclock, but that mobo will be dead in approx a year I predict. MSI mobos don't live long overclocked IME.

It's a rock, it will sink to the bottom of the river faster. :laugh:

Finished 330fsb testing!!!

Things are a lot different now. With locks on the boards, vcore not that high, AMDs unique memory controller ondie, I am wondering where much of the stress is going to be....

I am popping off NB chipset and placing some good thermal paste and maybe new cooler on it (haven't decided). NB chipset now feels fine (compared to past intel systems). POwer caps are not as blazing hot as past Intel systems as well...

It will only (likely) run this speed for another 4 months and then it will be retired likely for an Nforce 4 chipset.....When I see one worthy of it...

 

[Zebo]

cool, All at 1T I hope...

You should run 5 and 6. Test #6 is the A64 failer IME w A64.

 

[Zebo]

Also in my tests ~290HTT unless you can run the 166 mem setting @ 3-2-2, 1:1 3-4-3 will be faster..

 

[Stormgiant]

Great news Duvie

I'm also trying to see if it's overall faster 9x290 or 8x320...

Do you use A64 Tweaker to change some options ?

Not sure what you mean....

At 290 I cannot run 1:1 even with cas 3 and make it stable. I have to go down to 280 or less and that is losing a lot of clock speed.


What I have found is that 2640 with this 150+ddr from what I was running with my geils helps me beat all more scores at 2700mhz with the 400ddr. Just like I have always said clock speed is more important and it takes alot of ddr speed to trump same amount of cpu clock....




What I want to get is 333fsb with my 3x multiplier to put HTT back to 1000, give me 2664mhz and the fastest ddr clock I can get stable so far...Then I will try to drop cas timings...

 

[modalone]

I tried
325 FSB
3 HT
3:2
8 CPU multiplier
Ram 3-4-4-8

No Luck though

I ran 10 pass all test cache on = passed

I then ran your suggested #5-#6

20 passes of each = passed


remember at 330 I am pretty much running them at spec.....


333fsb was a no go at current vcore, vdimm, and cas timings....I dont want to give more vcore...gave all the vdimm I have...and cas 3 will suffer a performance hit that will totally take away any added benefits of 550ddr....

Just set mine at 325 x 8, ram at 166 divider and 2.5-3-3-8. All semms fine so far. Will be testing it out the rest of the day. On another note, the northbridge really needed some AS5, as I had problems running 3d 01 and other heat intensive programs (prime as well) for a very long time without the rig locking up. took off the HSF on the NB and put on some as5 and low an behold, ran right through 3d 01! Love this board!

 

[Duvie]

Any special tips for removing the NB chipset???

 

[jpetermann]

it was not hard at all. Just have to remove the mb from the tower, and then there are push-pins to get it off. There is some white goo on it, which cleaned up very easy. You have to push the pins in to be able to squeeze the bottom of the pin together so it will slip out. Very easy though

 

[Duvie]

Alright...I will be doing that later...Good info for others...

 

[wicktron]

GSkill is really some amazing stuff

I doesn't sound like something coming from you...
It has been "word on the street" for several weeks now, that for big htt on Msi Neo you should do that "trick" when you get the board.

Yeah I know I never got around to it in my overzealousness to get started with this chip. I never thought it was an issue cause I was not trying to go much over 290. IN my recent attempts I know I need to do it. Again my chipset HSF is not hot at all.....

My zalmann hsf/ heatpipe contraption on my 5800u floods that part of the board with cold air. My new house temps in my office are at a nice 68f where I like it.

Pastorjay says very hot...I am not really even much over warm...
