790gx/PH II

[chew*]

Well my board finally arrived and since the PH II thread is a little cluttered I decided to start my own thread as I will be documenting alot of results and settings and comparison.

System specs are as follows and subject to change. I will note any changes made as I make them.

Motherboard - gigabyte MA790GP-DS4H
CPU - Phenom II 940 AMD ( courtesy of AMD )
Memory - 4x1g corsair ddrII 800/OCZ 2x2g ddrII 1066 [*EDIT*] These have been swapped out for 2x2gig OCZ golds (1066 5-6-6 2.1v), they do so far over 1100mhz @ 5-5-5-15 2.1v on this board.
PSU - Trusty old seasonic S12 500W [*EDIT*] This has been replaced with a PC P&W for general purpose and crossfire testing
HD - trusty old 36g raptor
Cooling - OCZ vindicator ( for initial, High end air, Phase and DI/ln2 results to come )
IGP 3300 for intial testing [*EDIT*] Currently using 2x 2600 pro 512mb in X fire [*EDIT*] Currently using 2x 4850 512mb in X fire

Initial setup and first power on was a success, it appears the bios needs updating. I will start with F3i.

All right XP sp3 is all in, registry is backed up for those OOps OCing sessions, couple of problems to note, Audio device on HD audio bus, ( had this problem on another board, I will tend to it in a few days ) and AOD ( AMD over drive ) doesn't seem to think i'm using an AMD cpu


*EDIT* fix for hdaudiobus, you will need to install the HDaudiobus driver before installing audio drivers, If you point it towards the unzipped realtek drivers it will install in XP, vista is a little more complicated and requires you to drop the files needed in the windows bin32 driver folder.

*EDIT* AOD 2.14 works fine and appears to report correct temps, bios reports bogus temps......

***EDIT*** those looking for max Oc's on board I highly suggest F2 bios for now, I will see if I can pull some strings for a better bios, If you are looking for an everyday use bios turn away now....
***EDIT*** F3o Bios is probably the best current bios for this board now with Phenom 2, Those attempting to OC with 4gigs installed and getting a paging faults error on boot should try this bios....

It takes considerably more to get it prime stable with a rather poor performing heatsink.... ( possible its the F3 bios holding it back atm, further testing will see )

2x1gig ddr2 800 quick test. Will optimize bus/ht later.


4x1gig ddr2 800 quick test (still on air)


4x1gig ddr2 800 test, with minor optimizations ( still on air )


A shot of some benches after the above prime run just to show stability (not performance)


A validation as well........


I did a 32m, then tried to run a cinebench and crashed, adjusted a couple things and got cinebench to pass, You will have to take my word for it that cinebench is more intensive than PI 32m as I'm to lazy to wait for 18 minute bench again. 4.0 air. Still not quite 3dmark stable, working on it, could be my IGP, its acting weird now at clocks that worked fine, I did hammer it preety hard last night.



Started to drop Volts and stress stability at lower volts. 1.475 and +.025 NB vid for 3720.
The benches I have chosen are best represtative of overall stabilty, etc you can get PI 32m stable but them cinebench crashes, you can get cinebench stable but PI 32m crashes, you can get both 32M and cinebench stable then prime or 3d06 crashes.......Pay no attention to scores as i was doing other task while obtaining scores, plus I ran them one after another with all programs open.


Next up is 3840 which is testing as we speak. It appears although I hammered it preety hard I haven't lost anything clock wise, nor gained, so much for burning in.....


3840 testing with the F3o bios from gigabytes site.......as you can see its far superior in performance to F2 at same clocks.


It also seems far superior in vcore needed......1.525 vcore .050 CPU NB vid

First shot with DI, bear with me as I was stuck using the IGP which limits my ability to clock NB ( If i go in windows with high NB clocks I get artifacts ). I was also stuck using 2 gigs of ram, namely because 1 of the sticks had alot of pressure against it with my doughnut and would not post. This botched alot of my results......

Picture show first......





No dragon platform is complete with out the dragon desktop







Insulation job, I was quite impressed with kneaded rubber, not one drop of condensation.



All cleaned up like it just came out of the box



Better than new



Back to work it goes.

DI bench results

System specs

Gigabyte 790gx
Phenom II 940
2 gigs corsair DDRII 800 5-5-5-18
onboard IGP HD3300
500watt seasonic S12
36g raptor (because it still works)
10LBS DI and a home made DI tube

My 3dmark scores were borked due to lack of ram but If I had to take a guess it would have scored somewhere around 3600.

I honestly didn't even screenshot it as I was pissed off at the results due to my lack of making a mount that didn't take the ram into consideration. I think I benched it around 4.7
http://service.futuremark.com/compare?3dm06=9762407

Some cinebench, No clue what i'm supposed to be scoring, seems low to me, probably IGP/NB speed limited.



Some PI and everest.


Same with higher NB


Max Suicide was 5+ gigs.

High end air results.....the product of all the grueling stabilty testing pays off in the end...........I should hope this puts naysayers about this boards abilities to rest.....I have only had this ram for one day, I'm quite sure I can squeeze some more out of them and tighten subtimings as well...........

Reserved 5 for LN2 Results

[G0ldBr1ck]

I thought AMD was gonna be sending you the AM3 chip?

[soundood]

Well my board finally arrived and since the PH II thread is a little cluttered I decided to start my own thread

how modest of you....lol

and isnt that board sitting on the anti static bag a little dangerous, it is conductive after all, used for creating a Faraday cage round the item?

look forward to the results chew*

[ubuntu83]

look forward to the results chew*

specially the LN2 ones.

[chew*]

I thought AMD was gonna be sending you the AM3 chip?

Eh I'm not to picky, maybe they forgot, maybe they just decided not to, either way I still plan to go AM3.

[Lightman]

LOL at your CPU Fan
really nice

Seriously tho I'm awaiting your scores (especially ones with HD4870 and mark06)!

Eh never had a problem on them before, If it makes you feel better i can throw it on a piece of carpet

[Frontl1ne]

Yeah, free chip is free chip. I'd kill for a free Phenom II

Have fun overclocking and can't wait for the results

[chew*]

which one Light? the dual fan blowing cold air in from outside, the high amp delta on the back side of the vindicator or the clip on fan FYI cpu temps 15C....... Hmmmm memtest just passed fine at stock timings with 2 gigs installed gonna install OS now.

[EnJoY]

Looking good buddy, we still on for Saturday then I assume? I'll have all my parts in by Thursday and I expect to have my initial results posted by Thursday day as I will be tweaking endlessly.

[chew*]

yah still on, initial testing just screwing around feeling the cpu out 1.325 volts got me to 3.7 typing and posting now at 3.8 with a .25v increase. Kinda in the dark here with temps till I get AOD situated.

Very nice! Mine is the same stepping, but a slightly lower batch...so I'll be looking to one up you however I can.

[G0ldBr1ck]

nice OC for just jumping in.

[EnJoY]

nice OC for just jumping in.

Me thinks he bluescreened.

[cdawall]

very cool hopefully i can share some results with you soon i have a ES on the way


and 3.8ghz is nice for air i saw 4ghz somewhere here though

[G0ldBr1ck]

crap, my 920 wont be here for 3 more days. I have 5 790fx/gx boards to try it in and find out the best for HT clocking.

[chew*]

Me thinks he bluescreened.

Sort of but the bluescreen i'm on isn't the BSOD

Yah working on that, been awhile bios is a little diff and I seem to have hit a wall at 3900. Must be something i'm overlooking or possibly bios, wouldnt be the first time a bios that actually supports a chip kills it's OC.

[cdawall]

are you on internal VGA?

i hit a wall on my 780G caused by the internal VGA swapped to external card and could push the HTT higher but that was an AX2....

[crazydiamond]

how much voltage did you need @ 3.9 and how much did you bump it to try to go higher?
