Dumo's MSI 890FX GD70

[chew*]

Lets start this off with a bang and i will add stuff later.

http://valid.canardpc.com/show_oc.php?id=1210266




Just a shot of me first testing it to make sure everything was in working order before i swapped heatsinks.



This board has secrets like it's predeccesor.











Thats all I could find without removing anything.

PWM sink is very warm to the touch just idling.

No HT fluctuation but vcore reports wrong in both AOD and cpu-z.

Turbocore disabled and C&Q disabled works



Battery of tests at known good prime stable speeds of this chip.



1m and 32m effeciency aren't spectacular.





Not my board so i'm not gonna hammer it in prime but i wanted to know the point at which my ram would not instafail prime 95.

Just by swapping to an older graphics card?

4.8ghz at 1.3v, gotta be a vapo right?

[Dumo]

You and MSIMAX did an early ops on MSI 790X last year

The board is in a good hand

None of those are 4.8ghz.

The highest I see is 4.48ghz. Wonderful clocks for how little time you had with it.

valid at top of post

valid is 1 core on air. Thats what the chip should do and thats what it's doing on MSI so thats a good sign.

on vapo 5.0+......I can vantage at 4.6.....

[FlanK3r]

what is real vcore?

Sorry to quote myself but I'd really like to know what took it from not booting to benching like a champ

Woops. My bad. Not sure how I missed that. I guess I skipped it and went to the pictures.

[Movieman]

Nice numbers Brian!

Bios V1.4 have compatibility issues with 4870X2 and 5970. Boot up ok with other Gpus

[Yancey]

Chew at this point what is your opition of this mobo, As of 5/18/10 a new bios has been released for the GRAF X card issue..

[richierich]

omg golden cpu only 1.3vcore????

on a more serious note, thanks always for your testing chew

[Genghis Khan]

Looks like I need to head over to the 4-sale section and post up my 790FX-GD70! Great work! I think you found me a replacement.

[chew*]

what is real vcore?

real vcore for valid. 1.55.

real vcore for tests at 4.5g 1.525.

real vcore at my known prime stable settings 1.48v.

Will address other issues as we go but first I wanted to find a baseline of how the board should react before I toss newer gpu's at it that cause issues.

Currently i'm afraid to run prime 95 on it. PWM runs very warm. If it was mine i would to see if it would blow up but it's not mine so trying to be gentle

So far noted 240 bus not bootable, 235 will instacrash prime due to memory, not my GTX2's though so i say 1800 6-6-6 is not bad

When Lan 1 or Lan 2 disabled in bios hang on windows splash/load screen.

When set OC dial to reset on boot, keep option comes back.

I usually don't take air benching to seriously or get competitive but my buddy mad22 is making my life difficult raising the bar all the time.

Madd I will see your 4.9 and raise you 50mhz

[FlanK3r]

Chew: uff, thats impossible! Normal ambients? Vcore? This last 2 resluts (mad and you), is challenge to for me...bad think, my limit will at 4850-4900 MHz with 1.55V ....And whats max superpi air run?

thats 1.6v i just am not fond of tossing 1.6v on air.

1m is 14.50 running 32m now.

Room is 72F whatever that works out to in Celcius.

Hmmm...so there are a few issues with the board, specially the NB area and HTT clocking...I think MSI has made the same weak PWM setup here as they have done on the MSI GD70 790FX. Fine for x4, but not all that good for X6...

Not sure where you got that info on the NB......

MSI has always clocked NB higher than any other board. We were hitting 5000NB on retail chips np....I doubt this board is any diff as i've been up to 3400 on air so far.

1m and 32m is certainly not this boards strong point but ehh ran it to show you guys.

Nice clocks chew*. Could have slack internal latency have something to do with the ability for higher CPU-NB clocks?

How much volts did you need on those 1600C6's for 1840 6-6-6 32M stable? Or can't you tell cause Dumo is not supposed to hear?

Yah we noted even with the other board it was stellar at validations, NB clocks insane and 3d was very good but was somewhat behind in 2d performance.

Likely something slack but nothing visible that can be changed to pull it in.

The ram is mine. Seems they needed 1.7 on MSI. I'm using them becasue thats what he has. Need to play with vidcards and drivers and issues next figure out bugs to list them then try the beta to see what it fixxes and breaks.

[Manicdan]

im a little lost, all these upper 4ghz runs are single core? on air? at about 1.5-1.6v? why do all cpuz show 6 core/threads?

Becasue cpu-z valid always shows 6 cores/threads on AMD.

The final 1m run and 32m run don't show any amount of cores considering it's covered
