BIOSTAR TA770 A2+ AM2+/AM2 AMD 770 ATX at the Egg

[Ugly n Grey]

I'll start benching Friday, I dug up an old Powerstream 620 to use with it but my eyes need more daylight to work with when it come to plugging things into motherboards. I did put together the basic package... teaser pic I'll post a new thread with the build process, I'm still waiting for the 3850 so I'll start with a PCI basic card and do CPU only. All costs in this will probably make an excellent budget gaming system. If only I played games ... lol

Nice...X2's do good with em..i cant wait for Biostar to get a More optimal bios with memory settings that work with Phenom.Also the Multiplyer function Dosnt work With Phenom at the moment..All my over clocks are just on FSB and HTsettings.

This is funny , Did i set a Ts770 FSB record, Also note the uber Low Multi

nice setup Ugly n Grey...
but u change the chipset cooler??

Yeah, I'm sure the passive cooler is fine for a stock box but I hope to
a) push this as hard as I can
b) I wanted to lower the height of the chipset cooler, the stock passive was just too high.

It's just a cheap LED solid copper cooler but it removes a point of air turbulence coming into the Ultra and stops (I think) the chipset heat sink from picking up some thermals from the video card.... I admit, I didn't even test the passive cooler, just changed it before I even fired up the board.

Edit: gOtVoltage that is a super low multi... wtf.... hehehehe

Polygon just posted a new bios over at rebelshaven, apparently this one allows for multiplier adjustment.

wow..updated.. i hope it can work well at am2 proc.. wanna oc my am2 proc..

[gOtVoltage]

The updated Mod Bios should work Just Fine on a X2 Im testing it as im typing ..

Heres a stock bech on 9600BE... CPU score is lot faster than my 6000+@3.5ghz which only did 2700+ for CPU Score Seems that my GTS is held back..This dosnt happen with X2 Cpu's.I believe its because the Bios cant properly optimize memory and HT while running a X4, thus it also affects Videocard performance. Using a X2 you wont see this type of problem..Ive read where Bad Bios was crippling the M2N32deluxe and Videocard performance with Phenom,,((Kazgirl)) has updated from a buggy Bios with M2N32deluxe .The new one she is using also doubled her 3Dmark06 and overall performance basicaly..Shes now @11500+ on the M2N32deluxe...This leads me to say that if a AM2 can get a boost ,the Ts770 is in dire need of a well writen bios..So far i can run 230fsb with stock multi..

Ts770 a Wolf in Sheeps skin.
Below is the First Bench Run @2300mhz and all stock settings//800mhz memory 5-5-5-18 2T ,,Running Newest Modded Bios from Polygon @ Rebelshaven. He's really on top of things for this Mobo

[tictac]

wow.. more bios from polygon. great. way to go..

[gOtVoltage]

By the way Polygons newest Bios works better than any of the BIOSTAR bioses..

Biostar has also removed the 116.BST from thier site! It did not work properly,,..NPT FID was suppose to be adjustable and was not for the 9600BE or 5000+BE from Biostar.

I believe the Mod from Polygon has fixed this for the 5000+BE...It is not yet fixed for the 9600BE though..

[JWilson]

Rebels have this listed as an alpha release meaning it may be a little buggy still. Their download page is here.....

This is what was added:

[gOtVoltage]

Also with newest Bios....NPT FID does not work on PhenomBE yet so this is with the FSB Only...

I have time to test Bios but no time to bench..Once i get what i feel is a decent 100% Oc ill start with some Prime SuPi and 3Dmark06...Im just working on what bios functions do what ,,Its getting realy interesting now!


The NPT Fid option had to be set Above 2900mhz to get 2760mhz..Although the Fid dosnt work for 9600BE , it affected the actual Mhz @boot up. Also the Screens below were with CnQ OFF! I Can run with it on ,but wanted to see what would happen with the Startup Voltage when set to off..I found it very interesting! 2760mhz Screens are below. no Bsod's no reboots, just crazy!

If i did not adjust (NPT FID) in this way it would show 1600mhz @boot or even some random overclock ..(Most interesting AMD i have Ever OverClocked)..Tweaking a X2 on the ts770 will be pure pleasure compared to playing with this thing.

All My Oveclocks are only able to run with memory @400mhz, Cant change divider it defaults to 400mhz..Only way to raise is by FSB overclock.

240fsb x 2 = Memory @440mhz x2 = 880mhz real clocks 5-5-5-18- 2T for now.

bro, can show some oc using phenom or X2??
waiting for Ugly n Grey setup

[Ugly n Grey]

I'm trying now with the stock BIOS so I understand for myself what difference are before I use a mod BIOS.

At stock volts with only a multi change on the stock BIOS I'm 3.3 Ghz prime stable so far. Cooling is the Ultra seen in the pic above, temps hovering at 33-34c when loaded.... (is that normal btw ?) ambient is about 22c.

Im currently trying the Mod Bioses for stability and to see what options really function and what dosnt under a Phenom 9600BE only at this time..

The X2BE 5000+ and 6400+will overclock with 300+ FSB and the 5000+BE can use the Unlocked Multis' from wha tive already seen. I havnt had time to test my 6000+@3.5ghz or have access to a Nice 6400+ for max clocks on my 770 yet! Regular X2's work fine as well as my LE 1620..

Im patiently awaiting more Bios tweaks for optimization on the Phenom, ill swap chips and Retest all settings with my 6000+ once the Phenom has working NPT FID..and a few more tweaks.

So if anyone else has a X2 on this mobo with the Mod Bios,, let us know how its functioning.

Currently ((Polygon)) is working with the Phenom tweaks in particular.

[xixo_12]

for the moment, i didnt try the mod bios, will try after get back my PSU from RMA, before this using the bios from biostar website n have difficulties in oc, the multiplier auto change.. so the clock speed will reduce n cant get any stabiliy there.. so sad, but will try later with this mod bios.. i want my psu faster

The Biostar Bioses are auto defaulting...The MOD Bioses YOU should RUN WITH PHENOM the stock bios will be fine for X2.

Also Make shure DUAL CORE OPTIMIZATION DRIVER is UNINSTALLED from system before you INSTALL AMD CnQ driver!

I had installed the Phenom driver and removed the dual core driver after , Its a big mistake! Simple to overl@@k.

It gave the TA770 and Phenom a 3000 piont performance hit in 3Dmark06 @ stock clocks @2300mhz with my GTS512mb.

((((This will only happen with a Phenom installed , it does not affect any X2!))))

I am still below what a 2200mhz Phenom should bench with simalar card due to the TLBpatch. this causes a 20/30% performance loss with my GTS512mb.

Tommorow i will install a 3870 and rerun my benches for a chipset to videocard comparison.

Proggress is very good with the TA770 Even though i still have the TLB performance hit and a fully un optimized Bios! this is with the Biostar 116.BST recalled driver. I now need to bench the Newest Mod driver with the changes i have done and see how this affects my Oc!

1st bench run @ 2300mhz Phenom and GTS512



(Same settings 2300mhz )
After finding and full removing Dual Core Optimization Driver.
ADD/Remove programs only removed it from the list and did not install it! Most likely because i had installed the (AMD phenom driver) before i uninstalled the (Dual Core Driver)

Temps seem about Right ,,Its very low TDP My LE1620 @3.3ghz on water is just below That and barely makes 24c fully loaded at 21c ambiant

You are only 2c higher than the 10c Delta ambiant differance which is good if i remember correctly.

Told you guys the TA770 is very X2 Oc friendly..Im Not trying to be smart ,its just worth every penny!

[Ugly n Grey]

I have to agree, in terms of the ability to OC my BE 5000+ the board is absolutely nuts for the price. I've switched to the current BIOS posted on the BIOSTAR website and that fixed the problem I was having generating high FSB's.

I'm currently sitting at +.050 voltage increase (1.425) at 3.25Ghz~ pushing the RAM . The sticks are a cheap set of OCZ's but I've managed to tweak some more performance out of them with tighter timings..... so basically I'm testing FSB at the moment. sitting at 250FSB and ram at 464~ 4 4 4 12 2T with the 13x multi

I had to push some more volts to stabilize the FSB increase, I may have a chip that's a little weak in the memory controller area. Temps are barely affected by the volt change (3c ~) and I'm increasing FSB 5Mhz at a time.

What I absolutely hate so far, is that everytime you enter the BIOS it drops the CPU multi by .5 .... how frigging annoying....

[xixo_12]

that why hate for.. why when restart it will drop .5.. no stability in bios.. hope they will fix faster..

[Ugly n Grey]

I have the cheap DDR2 RAM running stable at 535 (1070 DDR 2 effective 5,5,5 15) with the proc running at 3210MHz. There is definitely more in the FSB of this RAM and this board. Once I hit a point I think is good I will try and tighten up the RAM again though for 40 bucks worth of RAM (total 2x1Gig) I'm not sure I'd be radically disappointed if it stopped there.

Downside: high FSB on my chip requires .05 additional volts in order to keep the RAM stable. Not that it's a bad thing, I have tons of cooling headroom.

Prognosis: BIOS needs work, but I have no fear BIOSTAR will fix it and guys like Polygon will mod it to make it even better, so there's a good future with this board. It sure is clocking the x2 nicely.

[xixo_12]

luckily we have polygon, so many thanx. if not maybe is the time to say gudbye to this mobo

[tictac]

looks like polygon managed to control nptfid of core0 in his latest mod. gotvoltage has you test it? wow.. would be great if we can have independent multiplier control for phenom..

[lemonlime]

I just picked up the board as well. Great bang for the buck, but the BIOS is definitely buggy. I'm using an X2.

So far, I've noticed the following:

• CPU multi decreases by 1/2 every time you enter the BIOS.
• CPU multiplier can increase regardless of what is set in the BIOS. Forcing the Vid to something other than 'Auto' seemed to correct this. I set 8x, and can get 10x once booted.
• HT Multi (1000/800/600 etc) reverts to 'Auto' after reboot, or entering the bios. This one is causing me headaches at high HTT, I think.

I'm also getting no-post after reboots. I have a feeling this has to do with the HT muliplier/frequency failing to 'stick' in the BIOS. On a positive note, I am able to get into windows at 350MHz I think that once these kinks are worked out, the board will be a great, stable overclocker--especially for X2s.

[xixo_12]

before this i'm using ta690g.. i have the feeling that this mobo will have same capabilities as much as ta690g.. so i just straight away to buy it eventhough the bios is still buggy..
ta690g is a very good mobo to overclock .. n it seem applies to this mobo.. but need to wait the bios first..
u can still oc your rig but will face some trouble...
