Am in same situation i can get my 720 to 3.7 stable and a 955 seems pointless! But after what have seen today the system seemed alot faster a 3.1 with the new bios using all 4core! It must be a memory issue with F3B or something like that! If i cant get the 4core workin on the next bios i will have to get a new 955! Seems a con really making F3b and getting people excited to just cut the support for 4core after!
I was hoping to see 4Ghz or better as the avg...at 3.7 stable I got no reason to move on other than been able to use newer bios with better memory performance.
I will wait and see what people get with the 955.
I moved to f3L and have 3cores and system runs real nice. I can get higher mem and better timings. I think I am going to keep three cores for a while, I like this bios so far.Quote:

If a heatsink fits on a am2 it should fit an am3 right?
Yes, any am2 HS would fit on this board. IMO, If you want somthing quiet and good performance, then this would be the answer http://www.newegg.com/Product/Produc...82E16835608002Quote:

Hmmm. I am running 4 sticks of patriot viper with point heatspreaders. Might make buying a hs much harder. And when you say that the hs is mounted vertical you are saying that the air will be blowing up instead of out the back?Quote:

Listing your bios and hardware would help greatly.........
An example would be what charge PM'd me, a HT limit with crossfire enabled and not being able to get over 215 HT
Not looking for problems like I can't reach 4 gig...not all chips are equal yours may just not be capable.....
If the problem is with an unlocked 720 you are on your own as well.....locked 720's I will be glad to help with.
I haven't been very helpfull and active in this thread ( i've been very busy ) so lets get this board worked out.......
First off vdimm and vcore read points.......This is important because you always want to know what you are truly sending to your ram and cpu.....
These are probably not the best points to read them but they are read points none the less.........
My particular board overvolts .02 and in my case thats actually a good thing with some ram i'm testing.......this is rather normal as it differs depending on PSU used ( in my case a PC P@C )
Please please please be carefull if you feel the need to probe around, missing and shorting 2 legs of an IC together will most certainly be catastrophic and most certainly not be covered under warranty.................I probed around untill I found the read points so as to spare someone else the risk of killing a board searching for them...........
circled yellow is vdimm ( optimal read point is likely under that cap near readpoint......kinda hard to get to when board is in a case or laying on a bench )
http://members.cox.net/hoobahans/vdi...er%20point.jpg
The Vcore is almost perfect on this board overvolting by only .01
circled yellow is vcore ( the leg to the left of it reads .01 higher, I'm preety sure that is the feed side and the leg circled is consumption side )

Thanks Chew*, I finished Stability test and moved to the ram for a sec. i am current @ 240HT ref 3.6 CPU and 1600Ram. Boot righjt into windows. Gonne try higher little by little. Looks promising.:yepp:Quote:

Just wondering if anyone can help i would like to know what setting are the best to change in memory sub timing drive strenghts to get higher clocked memory!
Honestly even if you had the same ram and the same cpu model the settings would most likely be different........
Trying to get tony to write up an article when he has time on tuning drive strengths as he is better at putting it on paper than I am and can explain them better from a technical point of view.....
Ok mate thanx!
i am not able to change bus speed, anything i tryed ended with system unable to boot, i tryed all biosses
please help, i want to OC more :D
Have you tryed taking the battery out and leaving it afew minutes!
i did but nothing, i have this problem since the beginning, i tought this was premature bioss, but after al those biosses the problem is still there.Quote:

Sound like the motherboard to me maybe rma it!
So I'm tackling Prime stability atm with some new ram........
Those pushing for 1600 ram speeds with F3L bios and a 955 I highly reccomend using the 1333 divider and 240 fsb.....versus the 1600 divider and start from scratch.
Swap dimm's. Your memory probably does not like the dimm placement it is in.Quote:

Like I mentioned in your 955 thread, I'm having all sorts of weird issues. Chip will not accept 1.55Vcore at 4GHz. This voltage creates more instability. Cooling is not the issue.
I'm starting to think that the board needs a new bios revision. Or maybe, its just me or the chip.
More voltage will not help the majority of these chips.....they like low voltage...Honestly I really don't have time to try getting 4 gig stable ( I did it on the ddr II 790FX board ).....I'm very busy and working on other stuff currently.......like specifically ram clocking which is currently horrible with the 955's on this board......Quote:

Little tip......errors at 8K, 10K and so on are cpu errors........errors 1024K 768K and such are memory controller/memory related.........
Example memory and NB ( internal memory controller ) clocks combined........These are the new low voltage OCZ animals I'm using here.....1.65v :cool: Death to high volt ram kits................
http://members.cox.net/hoobahans/amimals3.JPG
Good info Chew. I see you we are in the same line of thinking with low voltage ram...I love my OCZ 1.65v Ram too. :-)
Yah honestly although the IMC appears to be impervious to damage with high volt ram ( at least for benching have not tested for 24/7 useage ) its not to keen about it......I notice after 2.0 volts its not very happy.....if you can get ram that can pull the same timings at reasonable volts I see no point in the high volt stuff.Quote:

I went with the low voltage of course and couldnt be happier. :-)
How much are those DIMMS? I am looking at getting the 955 and 2x2GB DDR3.Quote:

What would be a popular heatspreader option or you guys not bothered?
Personally I care more whats below them:DQuote:

For the higher end ones, the reapers are nice, but due to potential issues with cpu coolers (Air coolers keep increasing in Size) I'd think the ones from the Blade series would be the best option.

I'll post back with results.
I think for compatibility reasons you guys should stick with the low profile heatspreaders....I can fit this ram under my true 120 and xigamatek without having to remove the heatsink........
We won't talk about what I had to go through with another ( we won't say names ) manufacturers "high" performance ram.........that apparently wasn't to compatible with the outer banks......
Slappa I think I was using +.275 for that screenshot.....It realy depends on cooling capacity and the chip though. I would highly reccomend for now using the F3L bios and disabling bank interleaving.....There will be a small performance hit but alot less aggravation.....the above was done with bank interleaving on but it took me quite some time to find the sweet spot....with bank interleaving off it will be far easier....
I will put some settings up once I am happy with them and feel they are consistent/reliable.
+1! :up:Quote:

All right in an effort to help you guys out despite the fact that I really don't have the time to be fooling around with prime stabilty on a "benching rig" I decided to pop up something that should be fairly easy to acchieve........
Forget the 4gig OC I did. I did it with NB underclocked to keep the heat down etc not geared for performance. Can you bench at 4gig with NB up yes.......can you Prime? I highly doubt it, not on air....

Last but not least.
For this particular ram dimms 1 and 2 will offer you the best performance/clocks, I will be tweaking them further in the next day or so but unfortunately from this point on the tweaking will be of no help to 90% of you......Drive strength tweaking tends to have individuality, not only what the user is going for but the individual cpu/motherboard and ram will really determine the best drive strengths to use.....
Trying to get Tony to post up a How To Tune Drive Strengths sticky as he can explain how to do this better than I can.......Be patient he is a very busy guy and has his plate more than full at present time.....
Also would like to note that bank interleaving off has a side effect/performance hit.......unfortunately the gigabyte needs more work in the ram department. I will be getting on there case to address these issues ASAP as shutting bank interleaving off is just a bandaid......However for now it will save alot of you headaches if you shut it off.
After thinking it over. I think I am going to RMA the 790x for the FX version. It seems stable and pretty straight forward. Would anyone say otherwise?
Chew what bios is that am using F3L and it doesnt look like that and thats the latest!
Well my guess is that the 955 BE unlocks some of these options ;) It's F3L off gigabytes website. As I stated.........my settings will help those with a 955BE............using these settings for chips other than 955 BE won't do much good........the IMC revision is not the same.....For future reference you can look at my cpu-z screenshots.........I include them almost always for a reason...the mainboard tab ID's what board and what bios I am using.....
In fact I know for a fact these settings will not work, 720 BE's require far more voltage.
955 will be ordered this weekend...if wife doesn't find out shhh:p: I will most like have to sell a 940.Quote:

I am a little worried about the cpu-voltage. Do you guys think, is it too much for 24/7? Temps idles around the 30s and never above 50C on full load.
Also, thanks to Chew, I found the solution for my random freeze ups. It was memory voltage and needed to be higher. Glad it is not problem anymore!
On average with air cooling, you will have about 200MHz more headroom with Vista 32 over Vista 64 at like settings once you hit the 3.7~3.8GHz range. On good water, the difference is about 300MHz between operating systems and on LN2, oh about 2.1GHz. ;) Right around the 3.95GHz range with Vista 64 or Win7 64, you will hit a clocking wall. So far today, we finally hit 4.3GHz stable on V64 with LN2, exact same settings on V32 got us 6.4GHz.Quote:

Honestly haven't used the MSI long enough to give you an unbiased opinion at this point in time.....the gigabyte is a very tough cookie however, it lags a little in performance it seems.....but has proved to be very reliable for me.
If you have choice, what would you pick? With situation like it is right now
Me personally, I would have one of each board.............in order to tackle a bench you need the right tool........some benches require 4gig modules......certain boards OC 4 gig modules better and have better performance........certain boards are better in CPU intensive tasks.......and certain boards offer more choices for 3d benching......the right answer is there is no answer......
There is a right tool for every job, it's up to you to use the right tool.....
Ok guys. I got some questions before I order this board.
How high can you get the NB clocks and does it come out of S3 Sleep mode without issues?
I think every setup/OC hits different NB clocks, but I can say that mine sleeps correctly as long as I am not at bleeding edge OC.Quote:

I hit 2.88GHz on the CPU NB @ +.300v . I could do 3GHz but it required too much voltage to warrant the increase.
Ok seriously last question before I order. Does this board have cold boot issues when overclocked?
Yes and no............it will give you a message sometimes....OC failed at boot.....hit delete....go into OC page....change Fsb back to manual, reboot and good to go ;)
ON a failed OC.....clear cmos......go into bios, load last known good and right back to where you left off ;)
:(:shakes:
Does the new bios fix those issues?
I'm on f3L and this is only when hammering an OC......if you have a 24/7 prime stable OC this won't be an issue.Quote:

Congrats...have fun!
I know that this is a thread about GA-MA790FXT-UD5P. But I got a nice ref-clock with GA-MA790XT-UD4P that I would like to show:
http://valid.canardpc.com/cache/screenshot/561801.png
371 mhz out of the box
Board is under normal air cooling, nothing special done. Just out of the box I can boot up to 360 mhz (with slightly raised vsb and vnb). 3d ist stable up to ~350 mhz, wprime runs at 360 and max validation is 371 (until now).
How good can you oc the NB?
To be honest I didn't try hard. But it seems that nb is a bad clocker. If I use stock reference clock I can't use 2.4 ghz nb - even with up to 1.3 volts. If a run high reference clock I can work with multiplier 6 (~2.2 ghz) but if I set higher multiplier system won't boot.Quote:

I think you are going to like it. :-)
BTW, any hints on when we are getting the same new ACC options that the other gigabyte mobo just got?
Soon I need to test something, need to wrap up some loose ends on another board first though.
Sweet news chew!
Thanks for letting me know. :D
Thanks Chew, I really like the use of my fourth core.
Same ere mate! Just ashame bios isnt up to scrath using F3B compared to F3L!
But finally there is hope bro20000.....I cant wait! :D
I just reilized something, if you are on F3B and if you have the warning message due to OCing on start up, it can be skipped by just using Ctrl-Alt-Delete. It doesnt really go away, but you dont have to get in bios and F10. It just restarts with saved bios settings, it is still annoying but hopefully with the new bios we dont ever have to worry about it.
yes, i found anything higher than 11 multi won't boot.Quote:

Preety sure it does.....we have had the NB all the way up to 4600-4700 on LN2.....Quote:

Sounds about right, took them awhile to get NB clocking up to par with the 720's. Will most likely take them a few tries with 955's as well.
I just recently got this board with the Phenom II 955 and I cannot boot into Windows at all with anything at 4Ghz or over. I've tried all different kinds of voltages, none of them worked. And yes, this is the first time I'm overclocking an AMD CPU, been cruising along with overclocking with an E8500 and a Q9650. Help please? I suck at overclocking.
The features on this motherboard is great, but I think the latest BIOS is buggy. Anybody having problems with it? Any news on the upcoming BIOS?
