You might be confusing HT with NB. You want to try and keep your HT to 2000 and your NB as high as it will go. I can do 2600 NB, some people can get higher, some lower.

No im not confusing it with Nb But ive read it somewhere.. The chipset limitation is 5200, 2600x2.

Well i know i read somewhere that someone did some testing and if you kept the nb synced to the htt it actually gave you a performance boost. Although just increasing htt is surely not good.

You can only really Keep NB and HT linked up to a certain point Bro.

2700mhz = 5400HT. Why becuase youll flood error the Mobo in most cases.

For the most part keeping HT below 2600 = 5200 will save your Mobo and lots of head ache.. I can run Mine @2700+.. But over time it too will Flood Error once the HT becomes unstable.

Tweaking Volts will not matter .
The only Systems i see Push HTT/HT are Dice/Ln2 and lots of those guys keep the HT low because it give stability..


There is no real gain with HT/NB Linked to 2700+ This usually works to about 2400mhz-2600mhz Ht Max and usually you run the NB higher anyway . It highly depends on the HT divider you are using to do this.

Even on DDr2 i get great performance @4000mhz+/2500mhz+ NB and 1200+ ram .. (HT @ 2400 or below.) Stable as a rock.

There is a fine line in balancing a System , One of those is not pushing HT past 2600mhz on any givien Mobo. You can run HTT to the Max but the HT freqency craps at 2600-2700 once things get real high. NB can go over 3000mhz but also depends on CPU more so than the MOBO..

The HT is 100% dependant on the Mobo and how good the Bios is for that Mobo. Matter of fact Even if the CPU is only Rated for 1600/1800 i have pushed 5200 easily. Some Mobos are just better than others but will eventually crash Above 5200HT (the Real working limit of HT) ATM.

Untill we see 5600Ht or 5800HT or even 6000+ Ht mobos mines staying below 2600HT

Well thats what i ment ofc, keeping nb and htt synced up to 2600mhz.

You really shouldnt eat them, but you do anyway..

Thats what Ht does when it goes too high.

Haven't seen anyone mention it yet but, there appears to be a F6A BIOS out for the 790X-UD4P. Dated July 2 though.

Anyone try it yet? What's the verdict?

I will,, this was just released and wasnt available a few hours ago lol..I just retweaked my sytem too.


UPDATE
I believe it has CPU Code update for New CPU's.

It also clocks ram better,, It also has Stable Ram timming when using 7-8-8-20 with 1066mhz ram.

F6A I can now run DDR2 @ 1220mhz @ 4ghz vs 1200mhz @ 4ghz with F5bios.

So far its a nice Bios..Im also using AHCI .

The Bios Temp is still the Same as before .

No New visable Features ,, just optimization Tweaks for new CPU Code and better ram stability i guess.

F5 with max Ram,,
I could never use 7-8-8 timing with F5Bios and Partiot Viper ram.
4068mhz/2486nb with 1200mhz 7-7-7 was a loose as i could go. I even tried @ 3999mhz



F6A with Max ram,,
Now i Can run 7-8-8 timing and @ 1220mhz NB 2500mhz @4ghz



Note:
I tried to keep the CPU clock as clocse as I could with Higher freqency on the Ram ,, Its definatly improved with ram timing on a 1066 divider. Now i can use 7-8-8 20 as before i could not.
Patriot ram uses a real wired timing ,,Since its taylored for Nvidia Chipsets on the 9600 EL Vipers 2gig kit.

Also this Pair of Viper9600's @ 1220mhz while using a 550 unlocked . The M3A 79-T deluxe barely did 1180mhz on the ram with Both of 720 and 550 @Stock locked cores.

Im happy

Great info, f5 limited my clocks because of the 8gb of ram i m using, hopefully i ll be able to clock up a bit with stability

[gOtVoltage]

8gigs is tuff with AMD on DDr2 to get high freqency with it is a whole new challenge.

DDr3 will be a nice switch on the Same CPU. I Almost have enuff Beer cans for New Ram and my first DDR3 Mobo LOL.

When i set up DDr3 for some friends i was like crap im missing out..But hey DDR2 and PHII@ 4ghz is fun untill then.

[jlacy76]

Flashed to f6a this morning. This is my best overclock yet.

3760 (235x16)
8gb ddr2 800 at 940 6-6-6-18
HT link and NB both at 2500

Ram did indeed go higher on f6a than f5.

I still can't get to 4.0 though...

Would you please take a look at my settings and make some suggestions?

HT 10X and NB 10x ,,
will drop the HT and NB some but will allow you raise the HTT for some more CPU clocks.. You should be able to get 3.8mhz with Air but it will be pushing it .

4ghz on Air with that much ram is gonna be real hard .

You can try with Deafult ram divider and just CPUxmulti to see how high it can go with out moving th HTT or NB/HT at all.

As For the ram speed go down one Divider and see what it gets ya too..
With 8gigs on DDR2 6400 around 800-900mhz is good. You should only need to use 2300-2400nb @ 3800mhz..


Also maybe lowering the NBvoltage chipset @ 1.3v instead of 1.4v ,, its easier on the Mobo unless your ram dosnt like it.
Your Volts are already getting kinda High for CPU with +275...
Maybe see what the chip will do with just Cpuvoltage +.200 . Phenom II's like the Vcore around 1.48-1.5 for 3800mhz Air..
Water will be even lower.. It all depends on you room temp(ambiant)

Another thing about your ram,, you can run 5-6-6 800 and it will be almost as fast as 6-6-6 900 basically.You Can also run the row cycle time@ 26 or even higher with all banks filled. this will add stability to your ram when clocking it higher too.


To begin this little adventure try lowering the HT and NB to 10x and Ramdivider dowm to 3x..first. Then try getting more from the HTT with same CPUmulti 16x...

You may even want to try 16.5 or even the 17x CPU multi with the Ram on 3x. Using a lower HTT.. which ever gets you around 800-850 on the ram.

Once you achieve 3.8ghz then tweak ram for speedTight timing) or bandwidth(loose timing)

your close now but i think you ram freqency is holding you back most.

Hope that gives ya something to work with for now.

gOtVolTage

[jlacy76]

Awesome thanks!

Ok, dropped to 10x ( 2330) NB and Htt
Dropped vcore to .225 but left NB at .275
3x on the ram 233x16.5 = 3844

my ram is running at 777 though and still 6-6-6-18, I don't have a 20 tras option.

Where do I go from here?

Ok I get it, htt/nb under 2400. At 2600 it was holding me back. Just went 1:2 on the ram (932) and 3844.

[chew*]

About HT guys.......

I have found it to have one benefit and one benefit only......

3d in multicard configs.......the more processing power of the cards the higher you can go.......I have tested from 2000-3000 and it breaks down like this.......

2300 HT good for say 2 4850's + 6 gig cpu.

2500 good for 2x 4890's + 6 gig cpu.

2700-2800 good for 2x 4870 x2's and or tri and quad 4890's.....

I had one gigabyte that would 3d at 3000+ HT link but scores actually got worse....

On air you are so cpu bottlenecked in 06 you willl never ever notice a diff....not even on phase change....this goes for most 3d benches as well.....

I did notice some gains with HT in vantage around 4200+ and multicard .cfgs but it could have been variations in the runs as the gains were rather small.

[gOtVoltage]

Nice info on HT Chew*,,

Ill never need to raise mine ,, since i only see 4ghz lol....

Is it just me or does the Boot up seem faster when the HT is Higher than Stock..?

Its always been like that on AMD's although there is no real benifit except for Uberbenching with Insane Multiple cards installed.


jlacy76

18tras is fine.

Try for More CPU freqency using the HTT .. bump it up in small amounts. You can even try lower CPUx multi. Just keep your NB .

720's like the 14x 15x multi's and you can use 2x ram divider with Higher HTT too.

Theres lots of ways to get more , It just takes time.

Just watch the Max temps..
Youll probally top out around 3870/3900mhz with that chip on air with about 800mhz on the ram.


Just take your time.

[FlanK3r]

I tried HT with only AIR 3700MHz, for superpi was the best about 2400MHz, for Cinebench about 2000MHz, for wprime 1800-2000MHz, others aplication as encode video or winrar not diferrent.

[jlacy76]

I think I will just stay at 3828, going past that is beyond my capabilities I think. I just bought this board a few days ago. My 720 was running 3 cores at 3.6 and my ram running at 800. I think installing this board was well worth the 100.00 upgrade.

I'm a photographer by trade, I often process 2000 13mb raw images into 35mb tiffs files at a time. Opening up the 4th core has cut my processing time by over 40%. My goal was 3.6 and 4 cores, I went past that, so I have to be happy given what I know to do in overclocking.

On a side note: I just helped a photographer buddy of mine build an i7 box. 920 D0, 12gb 1600 ddr3, P6t. We overclocked it to 4.0 and ram at 1700. It's a screaming beast alright but surprisingly, I'm not "that" far behind him in time it takes to do our work. When you consider what he spent vs what I spent, I win for price/performance. He spent more on just his motherboard that I did for my 8gb of ram + a 720 + this MB. In actuality, processing the same number of 2000 files takes me 3 minutes longer.

[gOtVoltage]

Now that is one fine example of why i use AMD,,
Money saved, buys beer, popcorn for a year and keeps the Girl friend happy on weekends

[jlacy76]

Well, not to go OT here, but AMD needs to step it up IMO. Intel I7 vs. Amd 955? I7 is something new + triple channel ddr3, 955 is the same old same old and ddr2 is still it's sweet spot. Add to that, Microsoft is working directly with the Intel I7 developers for Win 7 which is the future for us, like it or not. I'm not an intel fan boy at all, but if I was building new it would be an I7 given the price of the I7 920 is roughly the same price as the 955. DDR3 cost the same, x58 boards are 100.00+ more, but given the fact the I7 actually uses ddr3 to some benefit, the price justifies the cost for something actually "better" this time. Yeah, I can buy a 720 for 140.00, hack it (maybe) and have a 955, but we found a new i7 920 D0 stepping locally at a B&M store for $200.00. IMO, the AMD price/performance advantage is slipping if you need serious bandwidth and actually gain some benefit from DDR3. The 6 dimm slots on some x58 boards are a big plus for people who are ram hungry. Fact is, Intel is moving forward, what will AMD do to keep me next time? I'm off my soap box now...

Seems I was not the only one with Lan problems on this board. We have another discussion going on here. http://forums.extremeoverclocking.co...81#post3490581
I think it's a combination of things, pwr management, drivers, wrong PCi-e slot and OS versions. Mine is working for the most part, but sometimes it STILL does not connect and I have to reboot and it connects fine. I am running win 7 (7600) and using the Lan drivers from that build and it's working now 99% of the time so I'm leaving it.

My OC failed last night, I let off the ram OC to 460x2 and 3798 on the core. The fastest I have ever seen this ram go is 922 so at 460x2=920, so I'm in the ball park.

[wez]

No it's shows installed, but no lights on the back. (that's new) I used to be able to uninstall the driver then boot and windows would find it, then connect. It won;t even do that now. I've tried win xp32, 64, win 7 and several fresh installs of each. I have pci-e locked at 100 but I'm not convinced it's locked and maybe it's corrupting the driver once I overclock. I'm using a usb right now to type this, but even it fails, so I have to uninstall the driver then restart, even that does not work all the time, so I have to uninstall the device not just the driver. The only thing I do know is this is my 3rd GB motherboard and the last two ended up in the trash and this one looks like it's headed that same way.

I have a single video card, it has a PCI Express x16. I "had" this card in the blue pci-e slot and decided to try it in the orange pci-e and when I did the Lan powered up and connected. Could this have been my whole issue all along?

I had/have the exact same problem on my MA790FXT-UD5P. But only when I use a specific bios (f3l). The other bioses I've tried works like a charm.
Can also be noted that I run my gfx in the bottom pcie slot.

[doompc]

I just did a quick testing with the MA790XT-UD4P:


This 925 is awful (no SuperPI @ 4GHz even with 1.6v), but the board looks very nice.
Later I'll try a X3 720 Black

[Rezag1000]

quick question for those with a 790X-UD4P

How does your CPU temp (TMPIN 1 in HWMONITOR, TMPIN 2 in AOD), compare to your core temps?

My CPU temps are MUCH higher than my core temps.

I am confused. Which should I be paying attention to? Besides, wouldn't it make more sense if each core was hotter than the overall "CPU" temp?

Thanks!

EDIT: with excel, I managed to come up with this equation: Core temp=32.592*ln(CPU temp)-88.185

TMpin1 reads the Bios Temp..
Thats what i go by when im UNlocked..

When locked i Go By CPU-Z and Coretemp.. They read about the Same and are usually close to what my DVOM read when i place a sensor at my W/B.


GMA 790X- UD4P ....EPP now works @1066 and Higher with out reboot Bios F6A has fixed the AUto Ram AutoEPP detect setting ....

Before when you would try and Run on the 1066 divider with Auto EPP..It would Shut down or Lock up PC.

Now setting the the Ram speed to Auto instead of 533/800/667/266/200 you can use (Auto) to detect Your EPP settings for DDR2 1066mhz and higher ram .

You are no longer stuck with 5-7-7-20 timing and buggy ram @default timing Of the MOBO if you were running 1066 that has EPP setting.

You can now set the EPP Auto timing which applies to your Ram Cas /trp and mid timings... It is even stable past 1150mhz now..

Sorry i didnt post this up above in first Post..
When i Clocked 1220mhz ram i was so happy.. I forgot all about the EPP and was trying to check High Timing stability which this Mobo never had Until F6A.

Tested with Patriot Viper 9600 2x1gig ,, Ram is good for 1255mhz @ 2.3v

F5 Bios was Only faster here because my NB is @2800mhzMG]
Using 800 ram divider @1150 ,, about the Most i could use above 4100mhz no matter what NB freqency or CPU multi i used. Since timing and Stability was a problem using 1066 divider i had to use the 800 divider .



NOW im able to use the 1066divider with EPP
Auto EPP (auto timing) and 533 to get this timing as my default with 1066 divider and while using any NB/Cpu multi combo,,

Good work Gigabyte cant wait for the Official Bios
