1st OC attempt - Page 2

post #11 of 33
Thread Starter 
Yes I set the divider to run DDR2 400.

I THOUGHT the steps were the ones I listed above, I got them from the guide (section 4) I listed in my second post (guide is also in your sig). I didn't start at 200 ref clock as the guide states.. I started at 240 because I already knew that worked, but otherwise I think I did everything. The way I understand the guide is with the above settings nothing is stressed but the board, therefore when I can't go beyond 240 ref clock, the board is the limit as the cpu is at 5x (not stressed) and HT link is not stressed, and memory timings are loosened. Isn't that isolating the max ref clock of the chip set (board)?

Again, I think we are talking the same thing, but some terms are so similiar maybe not.

Steady, sorry if I'm misunderstanding you. Have you tried 250HTT * 10x? Have you tried applying some voltage to your chipset. Before doing so please make sure you have adequate cooling.

Let us know

Good luck

No. The highest I've had it that worked was 240 * 12.5 . I have tried
245 * 5x , but that no booted. So I'm assuming 250 * 10x will also no boot.

I haven't tried increasing voltage to chipset yet. (Not vcore correct?? as thats the cpu??).

I'm at work atm, so can't actually test any of this now.

Steady, when you get home give 250HTT * 10x a try and let us know if that works. 245HTT * 5x might of been just to low. Was it not POSTing or was Orthos failing on you?

Good luck

O.K. I'll give it a try when I get home. It wasn't posting at 245 * 5x. It went to safe mode (not windows safe mode) motherboard I guess, gave me the option to enter setup or continue. I entered set up and returned to the last safe config. I never got a chance to try orthos at that setting.

Thank you for you patience, I'm sorry if some of this isn't making sense. Just so we are on the same sheet of music. This is the section of the guide that I used to isolate my Motherboard (guides wordings), which is the same as isolating the chipset (your wording).

Ok, time to get started! Set your computer to the following values (i.e. take them off Auto and manually set them to the following):

Reference Clock: 200
CPU Multiplier: 5x
HT Multiplier: 5x
CPU Voltage: 1.35v
Memory Setting: DDR2 400
Memory Timings: 5-5-5-18-26-2T (keep all other timings on Auto)
Memory Voltage: Whatever the default voltage is for your memory, you should have already researched and figured this out before attempting to overclock.
Motherboard Voltage: Whatever the default voltage is for your motherboard, you should have already researched and figured this out before attempting to overclock.

Save the settings, restart the computer, and run CPU-Z to verify that the settings took effect (CPU speed should be 1000MHz, HT Link should be 1000MHz, memory should be 200MHz, timings should be loosened, etc). You’re now ready to overclock! Do the following:

1) Increase the reference clock by 3-5MHz, go to step 2.
2) Once the computer restarts with the new settings, run an Orthos Blend Test for 2 minutes. If Orthos ran for 2 minutes with no errors, return to step 1. If Orthos failed before the 2 minutes was up, go on to step 3.
3) Drop the HT multiplier by 1x, go to step 4.
4) Once the computer restarts with the new settings, run an Orthos Blend Test for 2 minutes. If Orthos ran for 2 minutes with no errors, return to step 1 and write down the reference clock value that required a drop in the HT Multiplier. If Orthos failed before the 2 minutes was up, then the problem wasn’t the HT Link, and you’ve probably reached the maximum reference clock that your motherboard can handle. You can try bumping up the motherboard voltage to regain stability, but this will probably only allow for a few extra MHz.

After completing this process, you should now know the max reference clock of the motherboard and the values that required a drop in the HT Multiplier.

O.K. 250 * 10 is also a no go, went to safe mode again. I only have passive cooling on the mb itself, here is a picture. http://www.biostar.com.tw/app/en-us/...c.php?S_ID=310. So should I try upping the voltage on the mb or is it at it's limit?

Steady, perhaps 240HTT is the limit. Upping the voltage on the chipset might be helpful. Keep an eye on the chipset temperatures when you do change the value.

Let us know if that works

Good luck

O.K. will do that tonight. What is my high safe temp for chipset? Looks like by my screen shot is was about 23 idle same as my CPU.

Thanks Thlnk3r for all your help, + rep even if I can't squeeze any more out of this. You've been alot of help.

Steady, I believe my nForce chipset can with stand temperatures up to 80C but I typically like to keep the temps below 45C full load. I don't have any experience with your board so I can't really tell you but I would to keep them below 40-45C full load.

Good luck

NF4 chipsets can take quite a beating in temps..my DFI UltraD used to be at around 55C for like 3 years..still going strong..anyhow that is a nice overclock. If you just cant get over 3.0ghz it could be the limit of the chip or you could try a few more things..the ram does sound fine and shouldnt be at its limit already but run a higher divider to get it out of the equation, also add a little voltage to your chipset, 1 increment should do it and the same for the cpu..
