My new tually 1.1A arrived this afternoon and I have been playing around with it for a couple of hours on my ST6. Early test results are...... not as good as my last tually 1.2 so far. It took 1.6V to get up to 125FSB, 1388MHz. Been running Prime95 for about 30min at this speed with no errors. Would not even POST at 133FSB 1.6V. Mem settings are 2-2-2-7-9 using 512MB Kingmax. Temp is 46C under Prime95 load using stock retail HS/fan.

I am a little disappointed because its not as sweet as my last tually 1.2 which ran at 125FSB 1500 at default 1.475Vcore. It looks like my 150FSB hopes for this 1.1A are out the window. I will be glad just to get to 133FSB after I do the VID pin mod for more Vcore. I definitely think intel is binning lower these new 1.0A and 1.1A cellys. I am taking the system down now to perform VID mod, will be back later to report further test results. Stay tuned ...

thanks for the interesting information! (so the 1.3 is the only one not yet 'touched' by someone here) max

The system is back up with the VID mod and I made it to 133FSB, but barely. The 1.1A is currently running at 133FSB 1465MHz 1.675V 49C under Prime95. If I try to go any higher in FSB/Vcore the system locks up because temp gets up around 51-52C. Looks like this is as high as I am going until I get better cooling. Will put the Orb on it tomorrow and see if that drops it a few degrees lower than the retail HS/fan I am using. The system is real stable so far at this speed, been running Prime95 for about an hour with no errors. Will leave it burning in overnight and if Prime95 is still running tomorrow with no errors I will be happy with 133FSB.

I had high hopes for this CPU when I opened the package and saw that it was a phillipines chip. Its a week 51 SL5ZE, retail box. Thought I might hit 145-150FSB with it but theres no way for that without supercooling if even then. I am not going to go to all the trouble of supercooling with a water block or pelt though. this tually CPU is just temporary until the PIII-S 1.4GHz tually that I want hits around $250 price range in about 6 months. I just want a cool, quiet, fast system until then.

I guess I can't complain if it maintains Prime95 with no errors for 24 hours at 133FSB. It sure is not as easy hitting 1500+ with this 1.1A as it was with the 1.2 SL5Y5 though. It might be interesting to see how high it would go with 1.75-1.80V and a high-end air cooler like an alpha or glaciator, might try that too. I will need it later for the 1.4 PIII-S anyway. In summary, I would call this 1.1A OC a limited success.

Go for a better cooler...

With a better cooler I'd bet you'd hit 140fsb.

My system/overclock has issues starting at about 42C, but originally were at 50C I'd see problems. A btter cooler is most definitely in order. Good job squeaking life from her :D

What are some recommendations for a high-end air cooler for these tuallys with IHS? Let me know what I should get, thanks.

What would be faster though in overall performance...

A cel 1.1a @1463 133fsb or
A cel 1.2 @1536 128fsb

Both CPU's I'm sure can be overclocked more with better cooling and more voltage, (at least its been proven with the 1.2) but lets just assume in this case that this is the best we can get out of them.

Wouldn't they be about the same in overall speed? I'm asking that because it looks like I am having problems going over 133fsb with my ST6-R (with Raid in use) especially in Prime95. I think its the Raid causing probs but I am pushing 49C CPU temps running Prime with my 600e overclocked with retail HSF. (my Millennium Glaciator is on the way!)

I'm still hoping to get a 1.1a, but the 1.2 has now come into play because I probably might not get over 133fsb without problems. (I need the Raid) But I'm waiting to hear more people's experiences with the 1.1a before I make my decision.

Do you think it would be better for me to get the 1.2 if I can only get a max 133Mhz fsb?

Thanks

For good cooling and probably way more FSB: Millennium Glaciator II w/ ASII.

Lap it and that'll shave down those temperatures to maybe mid 30's full load.

Anybody here know how many degrees you drop by removing the IHS? Thinking of doing a little surgery, but only if removing it will drop 5C degrees or better under load. I dont think its worth the risk unless you can get at least 5 degrees lower temp. Anyone who has successfully performed this mod please let us know how much temp improvement you got. Thanks

it wont drop the temps all that much. I think 5C would be more than you could expect. 2-3 is what i think....
Spoode has done some work with de-capping other chips, have a look yourself

It seems he has had mixed results....
So, if you can afford to burn one.....

I'm using a Glaciator II on my 1.2 Celly and even at 1.8v temps under load top out about 40C. Comes with a blister pack of ASII. I did lap the sink and IHS.

I have around the same results with mine.

As you can see from this heatsink test (http://www.overclockers.com/articles491/) , Joe calculated that the cap was worth about 2°C.

I just ordered a Glaciator II after reading Joe's review and the above recommendations. This cooler looks awesome...hope it will get my 1.1A up to 140FSB stable.

Does not look like removing the IHS is worth the trouble/risk for only 2-3C improvement. Thanks for the replies... will let you know how the 1.1A works with the Glaciator II after it gets here.

I have my wife's Celeron 1.0a running 1.43GHz at 1.71v. I lapped the heat spreader removing about half the material, using an old FOP38 with a YS-Tech 27cfm fan, artic silver II, max load cpu temps are 39c.

Her motherboard is an MSI 6337 LE5. With the cpu voltage mod the bios gives me settings up to 1.80v. But the board will not boot with anything above 1.675v (bios reads 1.71v). Had the same glitch with her Celeron 800@1100. The bios gave me options up to 1.90v, but 1.80v was the maximum that booted. Tried the cpu mod on that for 1.90v, but again the board would not boot. I have flashed to the latest bios, no improvement. I am kinda frustrated because this was oldfart's cpu and he got 1400MHz at 1.675v, 1.71v got it to 1430MHz. Cooling is good and I know it will hit 1500MHz+ if I could juice it at 1.80v. Any ideas?

Vid pin....The problem you mention was the exact same one Oldfart had and is common among 815 chipset mobo's (it is therefore not 'isolated' to any one manufacturer as it is not the fault of the manufacturer)....Dosen't look like the Gigabyte mobo was a poor overclocker at all - Just as I said! Considering your results are about the same as his....

The mobo tries to boot on the 'default' vcore (1.475 volts) and switches to the user defined vcore in the bios at the bios post screen....The way to fix it is to 'trick' the mobo into thinking the default vcore is higher than it is (1.6 volts is a good starting point, or whatever is easiest, but I would consider 1.6 volts to be a minimum).

Good luck!

Is the glaciator II better than the sk6, becasue I'm not getting very good performance out of it. I have the sk6 with the 7000rpm delta and my temps at idle are 44c at 1.703ghz . Now my coolermaster with the delta running seti@home for 9 hours are 42c at 1.703. Can anyone help me out as to why the coolermaster gives me better temps when I oc compared to the sk6 and the sk6 has been lapped to. Is the glaciator II worth buying.


heres my celeron/tualatin @1.703 1.703ghz (http://community.webshots.com/album/25562246TNHtGnyieo)

I have removed two IHS's without a scratch to the IHS or base of the CPU. I have also made a shim from clear packaging tape that works very well and allowed me to place the HS exactely on the core. I have also covered this many times and at the moment I don't have time to find the threads but they are here. I explained how to remove the IHS and also make the shim for it. I would not do it without a shim. You have such a sweet chip I would not even think of doing this without knowing exactely what you are doing. You could send it to me and I could remove the IHS for you as also add the shim as it is semi-permanent:) I would hate to see you muck up such a sweet chip as the one you have!

In other words clock your chip down or find better cooling. I would be happy with 134fsb!

Thanks ol' man for clearing that up. I didnt really want to do it I more or less wanted some suggestions on better hsf for this chip. You know it's weird as the days go by this chip seems to go a little higher each to time. I started a burn in at 1600 mhz at the default voltage and let it run for 36 hours with seti@home and everytime I do that it goes a little farther everytime. Who know, but any suggestions on hsf would be a big help.

Lucky. You've got a great chip there. Despite more than a week of burn in at 800 and 1.8 v, my own Celery 1.2 has not budged from its original high.

When I first got it, Prime 95 Self test would complete at 126 FSB but immediately error out at 127...and it's the same thing now. :\

The Glaciator is a great HSF. The Glaciator I is an even better deal at 20 bucks from the website. I can't think of any other HSF that comes close in terms of bang for the buck.

Thanks for the help ! Also when you tried to get 127 fsb was it the explorer exe error or did you get the bsod.

Sklathill
01-15-02, 09:46 PM
No, just errors in Prime95. I think I'm going to settle in on 1.52 GHz. Do a day of testing at 1.8 v to make sure, then I'll pop the voltage down until I get to the lowest while still stable.
