Overclocking and Need Help....

[BC]

Hey BC, when I was running at the faster FSB and it was giving me the error I had the memory timing at 2T. I only changed it to 1T after turning it back down to 204 FSB. So far after 3 days it hasn't puked on me or given me any errors.

Ok... so running at 204 FSB, you can get away with a 1-tick command delay.

the previous FSB speed was too much for 2T (it must have been a 3 or 4T need then... something was wacko.... or is the BIOS backwards??? )


May I suggest that once you are certain you are stable ... write down your settings... and then just switch to 2T at 204. See if that runs ok. It better, otherwise you have a hardware problem and need warranty replacement.

Once 204-2T is stable (2T because you have AT LEAST CL2) start
stepping up 1 or 2 Mhz at a time... you better make it to 210-2T.

210 vs 200 = 5%... I'm sure your board is not THAT restrictive. Most
specs are +/- 10%... unless you require tight tolerances (like in power regulation which is +/- 3%).

If you can't get even 204 at 2T to work, I'ld get the warrantly replacement saying the board wont run stable at specs. All you have to say is you have a NewCastle instead of a Clawhammer core and their tech support folks will understand.

let me know please how it works out... I'm bigtime curious now.

BC.

I am anxious to try OCing more this weekend. I downloaded a new BIOS that finally fixed my temperature reading 70-75 deg Celsius under a load so atleast now I know where I am running. My die temp. is running at 123 deg. Farenheit under a load which is cooler than my XPs do. My Asus board confused me because it didn't read the die temperature so it was always reading about 10-15 deg Farenheit cooler on the same chip.

Keith...

PLEASE tell me that's 123 F ?????? Otherwise Glad you found out where the readings were coming from and why... ALWAYS good to know.

The chip should run cooler overall.. My NewCastle (at Dad's) is running 42C typical under load... 44-45 MAX under extreme load at 210 w/ 2T.... but it is still a 32 bit bus... so the dual channel-ness of the Newcastle can't be used (it's in a 754 pin package).

If you read my other posts, you'll find Im in a BIOS or burnt hardware
situation... and it's also memory related.

1T vs 2T is available on Newcastles and dual channel machines.... Please watch out and make sure you have a dual channel machine with that 1T setting.

I'm trying to get some details from ASUS about how they implement the 1T... if it has anything to do with single vs dual sided memory boards, then I definately know they have a bug and aren't taking the switchover time into account.

I'm going bios hunting tonight myself.... I'll report back if I find anything.

I think I found a bug. I may drop back a rev and see what happens.

Any suggestions?

I managed to OC my amd 2400+ into a 2600+ by upping the fsb.

But before switching it on, I reversed the air flow on the cooler as Chuck suggested somewhere. When I started, temp under predictor load went up to 60C.

So I reset the fsb but the temp stayed around 57-58C.

Question: could I have upset the "gunk" between cooler and chip?
should I reseat it with as5?

[BC]

Stu,
Obviously, put the fan back the way it was for now and
get AS-5 ... it has the best thermal conductivity going except for
certain very expensive ceramic glues.

just remember that w/ as-5 a b-b size (or gain of rice) is all you
need.

I dont understand the temp rising when you flipped the fan, but if you
can tell me which one you have, it is possible your model doesn't
draw air cleanly that way...

You will gain more from better compound than flipping the fan.

a rule of thumb i always use... If you break the bond between cpu
and heatsink... you wipe it all off with alcohol and start fresh.


let me know if i can be of any other help

Yes, I think that is what happened. The bond broke when unscrewing and rescrewing. I could see the whole thing rocking as I was reseating it.

So, I had a Copper Silent 2L from Arctic Cooling sitting around, added a rice grain of AS that came with it (sorry no AS5) and fitted that.

The cpu is now oc'ed at 2600+ from 2400+ and runng at 55C under load.

I'll leave it for a few days to cook.
