OC potential of Phenom II on SB600

[MadUser]

I have clocked a 920 with 284x12.5 on Gigabyte 790fx/SB600 board. It works just fine.

correct me if I'm wrong but your CPUZ validator shows SB750.


Edit:

Kei,
you managed almost 3.8GHZ with 790FX/SB600 chipset on FSB tweaking?
this is an amazing score I must say.
if I'll get 3.5GHZ-3.6GHZ I'll be more than happy

So I guess this means that I can buy the Gigabyte GA-MA790FX-DS5 with the X4 920
and be very optimistic...

Thanks

I have 5 Different 790fx/GX boards I bench with. My 2 favorite boards are The AsRock in my CPU validator link and the Gigabyte 790fx-DQ6. In the past I have had 2 Giga 790FX-DS5 boards and they suck. I cant recomend you get that board. It has awful power regulation and allot of bios bugs.

haha Kei, I was just about to go look for your posts and link MadUser to it, but here you are buddy

Not sure how you thought I was on SB750, but look again at the first Everest shot and it shows you ASUS M3A32-MVP

I never bought an SB750 board because I was waiting for AM3 to be released before I bought another board.

As for clock speeds, I went all the way up to 3.71Ghz on the stock heatsink/fan combo so these processors have no problems clocking upwards by very far amounts at all even from the bios.

If I had enough voltage available I don't doubt I could've hit 4.0Ghz on this processor but I don't have the voltage available with my current setup. 1.552v is the top setting I can use with this processor and I don't think that's even a truly reliable setting anyway. I settled for 3.5Ghz as my max clock so that I could have everything else nice and even...can't help it I like 'round' numbers even though I could go higher.

I still use 2.8Ghz as my setting everyday since even that is more than enough to do pretty much anything I want. When I'm benching or doing some encoding or photo work I might bump up the speed but even that is rare. I just had to know what it could do if I do end up needing it.

well,
i can post at >300mhz htt on an amd 770/sb600 board with phenomII (this is BETTER than with a X2 6400+) and i have been running the last 2days 9 hrs etc at 275htt without a hitch.
benching at about 285 is possible - im limited, btw, to posting at 275 not by the chipset or cpu, but by the pwm. OCP trips loading windows with much over 2500mhz nb, and i have no control of nb multi so 300 = 2700mhz nb = far to much for the pwm.

i cant comment on maximum clock, but it seems that sb 600 boards have no excuse not to run high speeds with even locked phenoms.

My Ph II 940 can do 3700 with my MSI-K9A2 with pure multi's. That's SB600.

I run 3.8Ghz on a M3A32-MVP fine. Phenom II 940 18 multi X 214

3.9 here on M3A32-MVP Deluxe Wifi Bios 1406......

Honda guy,

been following these threads but sine AMD rig is still down I havent messed around with any AMD lately so i've been quite

Anyhow, thats great for a SB600, think you can do better with a SB750???

[Lightman]

i have managed 4.4GHz on air, just look at my sigb
4.3GHz was pi1m stable. I have not push for high htt but still benched at 275htt

Been able to hit 4.1 on M3A79-T, so far still testing out this chip

There is no difference in the clock between SB600 and SB750 as said several months ago. Mine chip also does more than 4200MHz for validation and 4150+ for benches. I've tested with the default multiplier x15 and managed to reach 4.2GHz(FSB 280). The board does 350 with alhlon x2, so I think it can be no barrier for the cpu, it only depends on the concrete chip.

What a shame, the MA790FX-DS5 is significantly cheaper solution for full CF mobo.

Bottom line:
1. SB600 is not an obstacle for good OC.
2. Gigabyte MA790FX-DS5 is not recommended at all for that matter.

Thanks Guys!
