need help unlocking the multiplier

I have an Asus A7v266-E mobo with a thunderbird running at 1.4 Ghz. I updated my bios to 1011 so I can select higher multipliers but i'm stuck at 10.5x. I have tried the L1 trick with conductive ink pen but to no avail. I have increased my FSB to 141 but like to increase the multiplier too. Can anyone help me unlock my multiplier?

 

Just use your FSB, using multipliers gets messy. Oh, also you can up the voltage.

 

Thanks for the reply. I guess I will keep on cranking up my FSB but is there a way so i can set it to 11 or 12x multiplier. I can see in my bios that it can go up to 15x but it wont go past 10.5x.

 

When i mess with my multiplier i usually end up having to reset the CMOS because its not stable.

 

How high can i keep pushing my FSB? Im currently at 143 FSB at 1.5 GHz I run the stability test all the time and my comp is fine. I really dont want to damage my comp until I rebuild a new one.

 

Just as long as your temps are good and your comp is stable you can take it as high as you want.

 

Below is one of the best sites for modding the AMD cpus.

Go to the workshop.

From what I could see there, the pencil mod on the L1's is the only way to Unlock the multies. The other option is to actually cut and/or reconnect specific L3 bridges to get a certain multiplier. Perhaps it would just be easier to get a good used T-Bred, Maybe a 2100+, running around 1733Mhz for $40-50. Mine will do 2405Mhz all day long. Your trying to flog a dead horse overclocking that T-bird any further. The 1400 was about it for that process. They started hitting a wall. That's why they went to the Palamino and then Thoroughbred cores. Just a suggestion...

 

thanks for the reply. i tried the pencil trick, the wire trick and the conductive pen and i cannot unlock my multiplier. i just want to see how much i can overclock it. im building a new system and my old system as backup.

 

You want to be sure you have nice thick lines, not too thick though... (with pencil i mean)

Heres a KIT that www.CrazyPC.com sells specifically for unlocking AMD processors.. its only 9.99 too!

Thanks for the sites. I will give it another shot.

 

Just wanted to say a few words about your concerns about damage. I have been overclocking CPU's for better than 10 years, probably 18-20 different ones, and have not yet burned one up. My present CPU has been running around a 33% overclock at higher voltages for nearly 3 years now with no ill effects. As long as your careful and don't get crazy with it, you should be fine.

On your memory overclock, You will not damage it by going a little too far. The machine will lock up or refuse to post or generally act flaky with blue screens etc. When you set it back a little it will be fine. You'll know when you hit the limit. In some (rare) instances you can corrupt a file and maybe end up having to reinstall your OS, or it will be mess the bios settings and you'll have to reset the CMOS and start over.

Most electronics components are speced to run at +/- 10% of rated Voltage so giving your stock memory voltage a 10% boost is within tolerance and could help stabilize it beyond stock voltage speeds. Maybe. Depends on the actual sticks you have. Too much voltage creates line noise that causes read errors. As you can see though I am running nearly a 12% overvoltage on the cpu and 8% on memory (The MB max of .2v and the only bad thing about my MB. Poor voltage selections). No problems so far. Use small FSB steps and just enough extra Voltage to stabilize things and I wouldn't push voltages more than 15% over with air cooling.

Because your MB uses fixed PCI/AGP dividers of 1/2 and 1/4 repectively, you are also overclocking them when pushing up the FSB. In my experience Video cards will do ok up to around a 155Mhz FSB give or take a little depending on the Vid card. The AGP divider is 1/2 FSB so the AGP bus is running around 76-77Mhz instead of 66 and the PCI bus is running around 38-39Mhz instead of 33 @ 155Mhz fsb (as an example) Your actual Mileage may vary...

I think you may still have a little left in the CPU, but the Thunderbird core was a hot one and desipated around 65-70 watts @ stock speed as I recall, so you'll need excellent cooling to take it much farther. Bumping CPU Vcore voltages will push it into the 80-85w range quickly. Caveat Emptor!

Your System memory may be fine with some tuning up to 160Mhz. but your video card may not like the high AGP speeds. Or a hard drive may not like the 38Mhz on the pci bus. It's all a balancing act. It's actually the fun part of o/c'ing. Finding the best balance that gives you the best performance on your hardware. A bump in Voltage, slightly looser Memory timings. You just have to experiment.

Good Luck.

 

Thanks for all the info. Currently im at 1.6 GHz at a 153/38 FSB with 1.75 V. My temp for my cpu is 60 c idle and 64 c with load on MBM5 is that too hot. I have tried to oc my vid card but its starts to act funny and i have to restart the comp. Im using the ATItool to oc my vid card but if i increase it by a mhz its starts to act up. Do you know why the image starts to get distorted?

 

Firstly, The MBM temps... Your Motherboard is using a temp probe in the bottom of the CPU socket to sense temps. These are notoriously innaccurate, and your CPU will be running anywhere from 6-10C hotter than reported temps. So I would bet that your CPU is running closer to 70-74C than 64C. That is getting pretty warm but Max Temp for the T-Bird is around 90 or 95C so it should be Ok. Cooler is always better though.

What CPU Cooler are you using? Could you mount a more aggresssive fan on it with a higher CFM rating? That could help, But it depends to some extent on your ambient room temps and how well your case is ventillated. As an example Room temps could be 22c, but the ambient Case temps could be 28C if airflow through the case is poor. It's hard to cool a CPU efficiently if your starting with warm air. (You can always cut a nice round hole in the side of the case and use a short duct to deliver room air directly to the CPU... I know! a bit radical, but you get the idea...)


As For your Video Card, I'd need to know what card your using to start. I don't see any mention of that in the thread. But at 153Mhz fsb, It may be an AGP problem. That's a little low to start causing problems, but every card is different. In some cases, setting your AGP protocol in bios to 2X instead of 4X can help that problem and gain you a few more MHZ, if that is what the problem is. So What Vid card are you using? Driver version?

Also, desribe "distorted". What exactly is it doing? with a little more info, I may be able to be more helpful.

 

Yeah i know that MBM5 is not accurate but i set it up if my processor hits about 69 c it will automatically shutoff. Im using the stock HSF that came with the processor but i gonna get rid of it and get a copper one. I have 2 intake and 2 exhaust fans plus my PS is sucking out air out in my case. I was thinking bout putting a 120 mm blowhole on top and add a watercooler but i saving all that for my new comp.

Currently in using my ati radeon 7000 vid card wit 64 mb. The driver date is 12-12-03 version 6.14.10.6414. I tried to update to the newest version but it acts up. I dont know how to describe it but when i surf the internet before the page load it like blinks. But when i rollback the driver it goes away. I see a lot of artifacts i think thats what you call it but its like a bunch of color spots all over the place when i try to oc it. I might throw in my bfg geforce 5500 wit 256 mb in to oc instead of the radeon but i dont know if i want to.

With your 2100+ running at 2405 it that with aircooling or watercooling? I was thinking about getting this processor. Is the processor multiplers unlocked on the chip?

 

IF your running ATi Overdrive, and try to run ATITool too, it will get distorted, thats what happened to me. So its run ONE or the other.

 

I only have ATItool installed and i still get the problem or should i install the radeonator. Which one is better?

 

Last question First... My Motherboard has 6 DIP switches that allow me to unlock the multipliers and set any multi I choose. Right now It's 11.5X204fsb.
During the summer months I drop it back from 2400Mhz a few Mhz because of the warmer weather. On a really cold day last winter, and using a vcore of 1.925v I had it running at 2500Mhz most of the day. Ran through all the usual benches, and it was quite stable, but running at that high of a core voltage is pushing your luck so I don't do it.

To answer your next question, I am using Air cooling as it says in my sig., A Thermalright AX-7 and a variable speed 80mm Y.S. Tech Fan that pushes 49 C.F.M. at full speed. During the summer it runs around 44-45c idle, and upwards of 50-52c loaded. In the winter, with cooler ambient temps, It idles around 38-39c and hits about 47-48c under load. I have lapped and polished the HS base, and am using Arctic Silver 3 HS compound. Thermalright are, IMHO, the best Heatsinks on the market.

As for your video card, I actually have a PCI version of the 7000 in an old machine I use for back-up in case this machine goes down. I have been able to overclock it a little, but not nearly as much as my last 2 cards, a Radeon 9500Pro, and this X800Pro. It sounds like you just got a card that doesn't want to overclock. There are no guarantees. The hot pixels you describe, are usually associated with video memory problems. Newer drivers are written more for the newest cards, with legacy support for older ones, so Your probably doing the right thing by running an older driver that was written back when the card was more current. You could try removing the HS and using a good quality HS paste to see if you can bump the Core speed up some, but it sounds like your memory is not going to stand up to any overclock. Sometimes overclocking is just Luck of the Draw as to what card you have and what it will do. Some overclock like Bandits and some don't do S***.

I have to cut this short and get ready for work... If I come up with any ideas, I'll post later today. Good Luck!

 

I have some silver compound on my hs and it dropped my temp a lil bit. I gonna get a copper hsf in a couple days. You are right how hot the t-bird get. I had to dropped it from 1.6 to 1.5 GHz cuz at 1.6 it occasionally locks up. I prolly need to bump up the voltage on the Vcore to keep it stable but not until i get a new hsf.
