Biostar Tforce overclocking stories??

Hi!
Can anybody help me with my T-6100 ocing.
CPU - A 64 3700+ San Diego E4 1.4 v
The MOBO can do only 247 FSB ( cpu multi - x7, HT - x1, SB<->NB HT speed - x1, BIOS - CU51MB02, memory lock at 133).
By setting the CPU voltage to 1.7v in BIOS (in CPU-Z -.1.616v) the MOBO can do up to 265 FSB
Is this result the problem of the board, or the CPU ?
I tryed with the latest CU51M127 BIOS, but the situation is same.
In both BIOS (CU51MB02 and CU51M127) there is no NB voltage regulanor, how can i set it higher?
Thanks very much for your attention !
 
biostar under volts though. 1.7 isnt what is really is. Sounds like the cpu is the issue to me.

My Biostar undervolts too, but not enough to even consider a 1.7vcore. 1.55vcore is the highest I would go.
 
As I wrote, the 1.7v CPU Vcore - is the BIOS settting, in BIOS "PC Health Status" the CPU Vcore is 1.6v - same as CPU-Z show me (1.616v).
I have a question to fireburster: With 293 FSB what is the NB voltage on Your rig ? Can You change it in the BIOS ?
I think, that the problem can be solved with the raizing up of the NB Vcore.
 
Hello All!


I'm back again! I bought a Zalman CNPS9500 for my AMD64 3200+, the stock cooler was making too much noise for my taste. It cools it ok, but I'm running a python script to eat up cycles, with the intention of curing the Arctic Thermal Paste I used. Now, I was noticing that my NB was getting quite hot while using the stock cooler. Now, I don't have any temperature measurements to back this up, only the fact that it was too hot to comfortably touch, so let's assume 45+C. Now, that bugged me a little. With this new Zalman, I have it clocked at 2.4Ghz -- btw, I got it to 2.7Ghz (well, 2691Mhz) bumping the Vcore up to 1.8V (in BIOS), 1.69V actual -- but it had trouble posting at that speed. You could get it to post if it started off cold, but memory errors would occur after a while (memtest86+) and it wasn't really stable. So my point it, I'm using Biostar's V8 overclocking program. I've lowered the video card fan speed, cause it was too loud as well, and now my XFX 6600GT runs quietly at 58C idle. (Used to be 55C idle, fan full speed). I have good airflow in the case. The PSU has a 120mm (12cm) fan on it, and the Zalman is equipped with a 92mm fan. Now to the important part. I'm running this python program to heat up the CPU and cure the Arctic thermal stuff faster. I feel the NB heatsync, and find it's WAY too hot to touch. Now, I bust out this old thermomiter, and pop it on the NB heatsync, right in the middle.

Nice eh?

So it starts jumping from the 20C it was at (room temp, been sitting for days with no one touching it, no hot spots around it, no direct sunlight...) to 30 in a couple of second, then to 35, then 40, 45, 47, 49, and 50C! My NB is running at 50C, and that's the heatsync part of it! I'm not using the internal GPU (as you can see my 6600GT in the background), so that shouldn't be it.

Picture 2 (50C, WTF!)

So, my question is... is the NB too hot, and could it be preventing me from reaching a higher clock speed?

Is this a dangerous temperature?

Do I put a fan on it? (God I hate noise, so expect this to be the last thing I do)

Do I call Biostar and tell them that their design sucks, and the NB is way too hot for practical use?

Thanks for the help.

I forgot... (running the 100% usage Python program)

CPU fan: 1380 RPM
CPU Temp: 48C-51C
NB Temp: 50C

CPU fan: 2445 RPM
CPU Temp: 45C-47C
NB Temp: 46C

i dont think you can change the nb voltage without a mod. Mines just stock. Im still using the default nb cooler also but i might switch it out for a zalman.
 
Hey I have a biostar Tforce4 SLI skt 939 motherboard and I tested it and it overclocks to 333FSB, I havn't tried higher, right now I'm just sitting at 260FSB, but thats cause I don't want to overvolt my cpu. (Gets to max of [email protected], max of [email protected])

Can You give a link or send me by e-mail ([email protected]) Your BIOS and settings, which are critical for the MOBO's OC-ing.

I tried with the 3200+ and the situation is same, but the results are better: 270 FSB - Vcore 1.4v; 290 FSB - Vcore 1.65v

One thing I dont understand: the CPU is underclocked (multi is x6 or x7) and the MOBO must do 290 FSB with the stock Vcore, but it won't. Only if I upper the Vcore to 1.65v I can reach the 290 FSB. For the 3700+ CPU the values are 247 with stock and 260 with 1.65v Vcore.

I want to define the max clock with the MOBO can run.

Thanks for Your attention!
 
Will the Tforce 6100 go above 300 HTT easily or is it a crap shoot depending on the board you get

I have an Opteron 165 that I know can take 2800 Mhz [ 312 x 9 ] easily

Crapshoot, my quit at 304.
 
Before I get this board can you guys post back the highest you got the HTT clock and whether you thought it was the board or the cpu that did not let you go any higher

Thanks
 
311 is my highest but i think its cpu also since thats with 1.65vcore and still failed prime.
 
put my friends opteron 144 in my board sitting the table with fortron 600 watt psu and zalman 9500 cooler

running memtest from the bios because i had no hdd.

9x362mhz for 3250 it would run memtest forever without crashing or getting any errors.
(i know this says very little for the stability of the cpu)

still thought it was cool i think this cpu will be stable at or over 3ghz :D

btw never tried a lower mulitiplier so dont know if the board can go to a higher htt

3x htt multi btw
 
Nice to see a lot of good overclocks. Mine isn´t impressive at all, 12x225 with an opty 150 on a rev 1.0 s939 T-Force 6100 board, it doesn´t go any higher no matter what I do. To even reach this I had to up the Vcore to 1,55. Ok, I can live with a poor overclock but what bugs me is the memory frequency, I can´t get it above 180 Mhz! Both Sandra and CpuZ confirmes this speed. Even if I set the memory frequenzy in bios to 233 or 200 it ends up as 180. Setting it to auto equals 112,5 Mhz, 166 equals 140! Has anyone seen this before?

I run the latest bios of Biostars website. My Ram is OCZ 3200 EL Rev 2.

Any ideas to whats causing this?
 
Hell, I can't even get 270 FSB on mine. Anything over 266 and I get crashes, even with a 133 divider and 1.65 vcore.

I have an Opty 148 at 2.8ghz, 255fsb with a 166 divider, timings at 2.5 cas, 2-3-3-6 with (2) 1 gig sticks of Corsair PC4000.
 
It seems logical when overclocking and lowering the ht ratio in the overclocking section of the bios to lower the ht ratios for the north to south and south to north bridge in the advanced chipset section. Any thoughts?

You're correct. Gained me 30htt
 
Is the on board video good enough to run pshop very smooth?

Could someone please dl cinebench and with the onboard video check out the ogl performance [ Graphics Benchmarks ], please report the cinebench ogl score and wheter or nor not you visually see any stutterring during the test ... the benchmark only takes seconds

cinebench.com/

Thanks
 
I just wanted to know if there is anything I should be aware of for this build ...

What drivers to install / not install ... any specific order, etc ...

voltages... cpu ... ram ... does the board undervolt ... if I wanted to run the cpu at 1.4, what should I set in the bios

Tforce 6100 939
Opteron 165

Is there anything like Smartgaurdian for the Tforce board. I installedmany times both the Tforce HW utility and fan utility but they will not work.

I do not like MB monitor, just a simple window like DFI smartgaurdian ... I need to monitor temps while I test for a stable oc

Also, I do not have a floppy installed so I installed the Biostar windows flashing program, is it safe to update the bios with this or with winflash which I also installed from the utility cd

Anything I have to do after updating the bios with those programs?
 
Something real odd is that core0 of the Opteron 165 is the weak core on this board. I have seen tons of posts around the net and 99.9% of the time core1 is the weak core during stress prime testing

I can not pass core0 at all with sp2004 and have much better luck with core1. I am using the default bios the board came with which is from 11 - 2005. I am at 310 x 9 with no chance of passing with core0 but windows works fine

Do you think updating the bios will help?

Also, why is my keyboard scroll lock led flahing when I stress test it

I use smartfan, and I updated my bios using winflash.
 
Has anyone had difficulty getting a stable overclock with this board? I'm using an Opteron 165 dual core, theBiostar TForce6100-939, and Gskill 3-4-4-8 HZ (black heatspreader) ram. I can only crank up my OC if I switch the ram to 2T, instead of 1T.

So far its stable at 2.5ghz CPU, 278FSB, and 227mhz RAM. Anyone else run into quirks with that ram and this board? Or have to change your command rate to 2T?
 
I just got a second TForce6100-939 in the mail and this one has colored plastic on the front-panel headers. It says "VER 1.1" and there's a little "A03" sticker on it. I'm anxious to get it home and compare this with the one I already have.

with the orig. bios I couldnt get anything stable oc wise.

I have that same setup but on an Ultra - d and with stock cooling and volts I get 312 x 9

On The Tforce 6100 939 using the 11 - 2005 bios I have the same setup [ cpu, stepping, stock heatsink and fan, stock volts, etc ... ] except this time I am using Ballistx, so far I am at 310 x 9

Disable Cool and Quit in the bios, make sure HT speed is at 3x and Hammer Fid is at 9x. Put vcore at 1.425, mem divider at 166, and enter in the memory settings manually
 
Turned off Cool n Quiet, unfortunately it didn't make any difference. I'm using 1.450v,currently on the CPU. Everything else is the same as what you specified. Prime crashes after 2 hours.
 
i just got some gskill ddr500 and the only way in this board i could hit the ddr500 was leaving the memory settings to auto. If i put them in manual i couldnt break 240fsb on the ram. Im currently primeing with 260 memory using 2.7vdimm and auto memory settings in a 1:1.
 
u can't use auto memory timings on to overclock.

the rams have an SPD setting which the board will default to under auto timing but the SPD setting are for DDR400.

u need to manually setting your memory timing to the appropriate DDR500 timings.
 
i have it set to 200 but the timings are set to auto like 3 8 4 4 . If i set those manualy i cant get over 240 fsb.
 
This is odd. I have 2 Opteron 165 with the same stepping, same stock heatsink and fan. One is on an Ultra - d and the other is on a Tforce 6100 939

On the Ultra -d, when idling, the temps report much lower and I think more accurate because i have seen tons of smartgaudian screen grabs from other users and they are are all the same. The temps are 30 - 32 celc

On the Tforce, when idling, the temps are 37 - 39 celc

Are you also geting these idling temps on your Tforce? If not then maybe I have seated the heatsink the wrong way ... I have the heatpipes towards the middle of the board
