Gigabyte GA-MA790FXT-UD5P Thread

[bro20000]

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!

[shaolin95]

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.

Alright so I have been unable to find an answer to this question. What would be a good heatsink that is going to fit on this board. I don't mind it being big and heavy (I'll just make a bracket for it) but I do want it to be quiet. I have been looking at a Scythe Infinity SCINF-1000. Would that be fairly good. 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...82E16835608002

One thing you need to watch out is the way the HS sits on AMD platform is vertical. So most the HS would be hanging over your first two memory slots(blue). For that reason dont get 4 sticks of ram with high clearance on them. you can only use two high clearance memory sticks and put on the right slots(white) but not on the blue slots.

I use this on 2 systems 940 and a 720

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?

Yes, the air blows up, unless you find or make your own mounting kit(like this http://www.xtremesystems.org/forums/...d.php?t=208592). I have the patriot vipers with the point spread pipes also and I cant put them on the blue slots with my xigmatek hdt-1283.

Here is how my memory looks like, I belive all the patriot vipers looks the same but just to make sure we are on same track http://www.newegg.com/Product/Produc...82E16820220371

Yea those are the type.

If you guys are having a problem with this board regarding bugs in the overclocking department......feel free to PM me......I'm not going to teach you how to OC the board but i will try to duplicate the issues you are experiencing to see if we can get it fixed...........Mind you I am limited to what hardware and OS I can use.....

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.

[chew*]

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 )



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.

Edit, Booted at these setting just now. To some this might not seem like a big move, but on my current setup it has been in the HT ref / Ram OCing department.

[bro20000]

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!

[chew*]

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.....

[bro20000]

Ok mate thanx!

[yaxo11]

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

[bro20000]

Have you tryed taking the battery out and leaving it afew minutes!

[yaxo11]

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.

i managed to oc my 720 up to 3.8Ghz but only with 1.4V, so i think there is a lot of oc potencial

[bro20000]

Sound like the motherboard to me maybe rma it!

[chew*]

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.

Chew. If possible, can you show me a 4GHz stable with the 955 on this board?

Not asking you to teach me how to overclock here like you stated against above, but just wondering if you have pulled it off.

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......

I have stated memory is the KEY to Ocing PHenom II's so this most likely is the source of your issue anyway..........try doing this instead.......And don't use 1600 divider for now.........if you can't get your RAM/NB(IMC) to pass prime blend you will never get the cpu to 4 gig.........You really really need to seperate everything into categories.........then try to mix them together.......Try finding voltage necessary to pass prime with higher NB frequncy with ram and cpu underclocked.........then try with ram clocked.............then turn those down and find voltage needed for a cpu clock only...........then put it all together............

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 Death to high volt ram kits................

[shaolin95]

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.
