Gigabyte GA-MA790FXT-UD5P Thread

[Cele303]

I'm still not blind

That is way too big voltage, lower it down man... 1.550v+ cpu-nb voltage is for ln2 cooling to achieve 4000+ mhz nb frequency, you can achieve your nb frequency with +0.175 (1.350v), maximum +0,225 (1.400v)...

This is my nb 3000mhz testing, 1.300v with water cooling, ram is not optimized, it can be tighter, around 1700 CL6, unlocked 550 in general have weaker IMC than 955/965 but there is no efficiency ih higher nb anyway...

It's still alive and ready for next step... If you better know me, you should know that I don't give a damn about "safety" voltages. I'll measure it with DMM to see the real voltages but tbh it's ok for me if it's working the way I want it to work

3GHz for NB on water cooling it's nothing weird and it's not big success imho.

[neo mike]

Never said it was something new or big success, have had the board 3 days just havent been able to reach it, and im not on water, its air. Im wondering why cpuz is showning wrong readings was my question. Am i detecting a attitude.

Man, I'm trying to help you here with some informations... No need for "I'm bad, I don't give a damn about hw" style...

So you think running nb 3000 1.30v with two times cheaper 550 X4 is nothing but running nb 3100 1.57v with 955 is kick ass result? Give your 955 1.65v cpu-nb vid for 10mhz more nb freq

[Bullet92]

Doh, you still don't get it. I never said that this is kick ass result with that voltage. I didn't say that I'm using those voltages for 3D benching. That was just for 32M and I was surprised when I saw 3100MHz on air with ambient temperature for 32M and 3150MHz for 1M. I can try lower it and tweak it more, that's not the problem but I'm time limited every day

[Cele303]

Yeah, nice story for PCE

[Bullet92]

If you think on the 1.36v that I've said, I didn't say anything wrong. The NB voltage is 1.36v but NB-CPU was +0.400V and that wasn't question there. If you have some problems with understandin my posts, you have my msn and speak there. I'm off with OT

[ah_khoo]

no super high nb freq nor high ram freq coupled with tight timing, but this is what i managed with some helps from ACC & old air cond in my room...

[stetsonaw]

just put mine in a couple days ago...

looks like i'll hang out here, as the thread i created on overclock.net has 2 people in it, me and another.

[neo mike]

Good Job Ah Khoo, im feeling some tension in this thread. Well im really liking this UD4P still deciding if i want to upgrade to UD5P, so far this is a pretty decent overclocking board, but have to see when i get my GT 1866 cas 7. Cpuz is showing 4.0 ghz, but in bios is showing 3.7 but 250x16x is 4.0 so maybe the bios is wacked out on its readings ??????

[stetsonaw]

i would about say flip a coin on that one.

[neo mike]

I thought that to. I did run sisandra memory test for bandwidth and 1632 cas 7 has quite a bit more bandwidth than ddr 3 1500 cas 6, but its very close, thanks for your reply.

[Stanley Pain]

How far should you push NB, and NB VID voltages and still remain fairly safe? I've got nothing in the red, but most of them are a tick or two down from the RED ONES.

[neo mike]

Need some help here, i just bought the corsair GT 2000 cas 8 4gig kit, i was hoping to get over 1600, well much to my surprise it wont even post at 1600, it runs fine if left on 9-9-9 ???? shouldnt i be able to hit 1700-1800 ? man my cheap patriot vipers did much better than this ?

[Bullet92]

What voltage and subtimings?

[neo mike]

Im running 1.65 which is stock , and im on auto its going to 9-9-9, i did try cas 8 and cas 7, but over 1600 is a no go, wont let me in windows at all ???

[Bullet92]

Stock HTT?
Try to go with 1333 divider if you running on 1600 now.

[neo mike]

yeah stock htt, i will try 1333 div and see what happens, i dont think im going to get far, but let me try.

[neo mike]

Well i upgraded to the UD5P, definitly has more bios options, now i cant even get my cpu to 3.6 could use some help, ??

Chew, right now I am at 3.9 OCCT stable under Windows 7 64bit with 1.488vcore
I am using the F3K Bios. Some people think the F3K is the same as F3L but with the added unlocking feature.
Since now I have a 955 not the 720, do think the F3L is going to squeeze that extra 100Mhz to get me 4Ghz under W7 or does that seem very unlikely?
I know there is not going to be a real difference between 3.9 and 4 but this is all about achieving a goal with air cooling under a 64 bit OS :-)

[neo mike]

Thanks for that link Chew, i will check that out, what is the best bios for this board i have flashed to F7, thanks again.

[chew*]

I prefer F3L. I'm not saying the unlock feature will cause you issues however I use the bios for the same reason I would use a board with less onboard stuff, less things can act up.

Less code needed compiling = less issues. Keep it simple.

The only real reason you should update is to fix a bug.
If your bios works leave it alone.

90% of new bios releases do not actually do anything for overlockability, if anything they adress bugs and sometimes limit overclockability.

The latest is not always the greatest, at least not for everyone.

Take the GD70 for instance. Latest bios's, now they have artificial ram clocks and NB clocking walls

[shaolin95]

I need to share this with you guys, and specially Chew thanks to his help.



Finally I did 4Ghz under Windows 7 64-bit

[neo mike]

Ok thanks Chew, i didnt know that about bios, i thought the more up to date, the better overclockability, i may try F3L, i dont even know what unlocking the cores does ?, been in core2 duo land for years, havent touched a AMD since the 939 FX days. So far this ud5p and the ud4p i had, i cant get any higher on my memory clock with this ud5p, i will keep trying.
