Hey guys, managed to get a bios for my motherboard that had decent overclocking abilities, so now i wanna overclock, sadly i dont know what to change exactly, i had a mess around on it but couldnt get anything that would run sstable without flagging some kind of bios deep alert.

The main 3 components im using is a Biostar Tforce 6100-m9 with an opteron 165 and 2gb gskill zx ram.

Lukcily enough its got a automated overclock and ive got it on the highest one which give me this.....
Automated Overclock
but i think the timings are a bit loose but is that just me.

I ve got the 4 main screens needed for overclocking but wasnt sure on what details to put in the fields so was wondering if u guys can help me out, maybe suggest some timings that should work and maybe if someone is kind enough is explain the obscure settings.

Any help would be great, Thanks in advance.
 
I wouldnt mess about with automatic overclock to much. I would look up a decent guide and follow that. You should be able to overclock it a few 100 mhz minimum.
 
Heya guys, right i managed to imrpvoe on the automated overclock quite a bit (well on the ram side)

Thing is i cant seem to push the cpu past 2250mhz (250mhzx9). as you can see from the pick above my ram is 204.6mhz though in the bios i set it to 166mhz.

Do you guys have any idea what i can do to my current settings to get a better overclock overall?

CPU Vcore is currently set at 1.4v and my Ram voltage is at 2.6(according to the bios)

Cheers for the help already guys, i gave that guide a brief look but got me a bit confused.
 
You need to up the volts on the cpu up mine is around 1.52 dont go mad though I thing 1.55 to 1.6 MAX! EDIT: BEST CHECK FOR OPTERON MAX VOLTS FIRST MINE IS A VENICE CPU.

(MY SETTINGS ARE: venice 3000 at 2.65, 9 x 295, 1.52V, 133 divider, 1T command rate, CAS2 2GB G.Skill ZX)

I would suggest you try the following steps:

Drop the divider to 133, a 166 divider will push your RAM too hard hence why you are failing prime etc.

HT x 3

and keep raising the HTT till prime fails

This will end up underclocking your RAM slightly but to not much effect as your CPU will be much faster

Google this: Quick and dirty A64 clocking guide
Its pretty good at explaining dividers etc also there is a script which helps you see exactly what multipliers etc are avaliable to you.

You wont be able to push that RAM too much but tight timmings are probably better than higher frequency IMO.

I assume you are trying all this in the BIOS as application overclocking is flaky at best! GOOD LUCK

Cheers for the help guys, ill try those as soon as these files have finished transferring.

Yes i am indeed using bios ocing as i finally found a good bios that has tonnes of options for me.

This is what im going to try and do:
Raise cpu volts by one notch
drop the HTT to x3
raise the cpu frequency to 270/280mhz
drop the ram to 133mhz (thought that would make it crap but will give it a go)

If that all works i will push the fsb and htt until it craps out, trying to find the best balance of them to see which one gives the best performance boost overall.

Any further tips would be great.
 
Don't worry about having the memory on a 133 divider with tight timings. Reports are that A64's run equally as good when at say 200mhz 2.0-2-2-5 1T as they do at 275mhz 3.0-4-4-8 1T. :)
 
Running a high HTT and a 133 divider will put you RAM roughly where it should be ie: 200Mhz, mine works out at 190Mhz, still bloody quick at 2.6 with good temps.

I can't get it to post at a 166 divider as the RAM would have to run at 240-250Mhz which it can't... if your board has more dividers (some do apparently?) you may have one inbetween 133 and 166. which may let you run the RAM closer to its spec. If you check out the website I mentioned earlier and also this:

http://math.gogar.com/athlon64.cgi

It works out your optimum dividers, multipliers etc. It let me confirm that I was heading in the right direction. Underclocking your RAM slightly is no big deal with tight timings.
 
right ive just done some more overclocking and i have now got it to this...

I was pushing the HTT to 290mhz, it booted the bios fine but wasnt booting windows. Anyone know why?

I did get an atapi bsod first time when i used these settings, but i restarted and it seemed fine.

Anyone got anymore tips and tricks that can help me out?

Cheers
 
Is that clock Prime Stable or super pi stable, even a quick test to see if things are okay.

One thought is I see your CPU-Z RAM timings are tight at 2,2,2,5, I have got them set to 2,4,2,5. this might help a little.

I think if you used a higher divider you would be like this
280/200 x 166 = 232Mhz or there abouts, too rich for the RAM.

That clock isn't bad tho.. Better than earlier :p
 
Right i messed with it a bit and i cant seem to push past this current clock (shown in previous post)

I tried your recommendation, but was the 200mhz on the ram or something else, cause ive only got 2 settings which are in mhz, one being the htt and the other being the ram.

Anyone got any tips for what i can do to push this to 2.6 or 2.7. i bought this chip expecting i would get 2.7 quite easily.

Cheers, Nixeh
 
Pci-e frequency is set to 100mhz.

Yeah i have tried other volts but it doesnt seem to even help it boot into windows.

I have had it upto 290 whilst booting bios, but it wont boot windows.

Anyone know good settings that should get me to 2.7ghz?
 
Could be that you're hitting your motherboards limit, I don't know how good that particular motherboard is.

RAM shouldn't be a problem at 2-2-2-5 @ 180MHz, which is where it's at now.

Might also be your PSU not giving a stable enough voltage under load. What PSU do you have?

The Hiper PSUs are pretty good, so it's probably not that that's behind your problems.

I'm unfamiliar with the Biostar motherboards - perhaps someone else who is could comment on their overclocking capabilities?
