View Full Version : Throwing in the towel on this Celeron 1.1a

Well after a little more than a week of trying everything I can think of, I have to throw in the towel. I bought a VH6T and a retail 1.1a Celeron in hopes of running it at 1463. When it arrived I was pleased to see it was a Phillipines chip and proceded to set it up. It would not boot into Windows at 133 fsb so I decided to burn it in for a week. Set the fsb to 66 and ran CPU Burn at the highest level for almost a week at 1.775v, (did the wire trick). The CPU consistently runs very cool with my Alpha and ASII at any speed, 30C at idle and never over 32C at full load at 124 fsb. Also it will now boot into Windows at 133 and everything runs fine until I try to play any 3D game or run 3DMark 2001. It runs perfectly fine now at 124 fsb but won't go any higher with stability. So now I have to decide whether to run the CPU at 1364 and suffer a decrease in performance in everything else or run it at 1210, (110 fsb), and my memory at 143 cas 2 and my other devices a little above default.
If anyone has any ideas I haven't tried please let me know.
I'm seriously considering selling the VH6T and 1.1a for much less than I paid and going back to the dark side.
Hmm I would say sell that motherboard and get a Gigabyte 60 XET I'm pretty sure its the mobo or something is the bottleneck.
Did you check the ram and psu?

You need more voltage!! Your Vcore is a bit too low, that's why all the 3D games crash!!
Just set it to 1,825V and it should be fine at 1466 MHz!! If your temps are OK, then I think you could go for 1,825V. My Celeron 1 GHz A is also runing at 1,825V and it'as stable now at 1500 MHz.
Hope it helps!:beer:
skitzer, I have that same mobo and chip...let me tell you a few things about mine.
I couldn't get past 123 with mine for almost a week. My HDD or either my sound/vid cards didn't like it. It may have been a little of my chip not liking it as well. I did a burn-in at max voltage (1.750 after the vid-pin) at 66FSB, then booted up...still a no-go. So, I ran prime95 and sandra for 2 days at 123FSB at full voltage. I turned it off and went to bed. The next morning, I booted up, went into the BIOS and set it at 125 (after talking to Pinky), and it has been all downhill since. It wasn't easy, by any means, and several times I thought I had a bum chip, and had wasted my money. Just remember, when you do a burn-in, you are "burning" all your components in at that FSB and voltage, not just the CPU. Try the burn at 120+ for a day or so, and see what happens. Also, check Sandra often, and keep an eye on your peripherals...HDD, vid, sound, and so forth...they all have to work at that speed. Also check your RAM timing, and do a few benches on your mem...it may be the bottleneck, as Yodems suggested. Trust me, I think even a crappy 1.1a could still get at least 133...these are some strong chips...good luck brother! :D

Well, the PSU is an Antec PP352X 350 watt and it powered my 1.4 TBird to over 1.6 with the same components I'm using now. I don't think there is a lack of power here. My memory is Crucial cas2 and is 3 256meg sticks. I have tried all different settings and timings with the memory and it hasn't made any difference. I will remove one of them to see if that matters and will also try moving them around to different slots. The max Vcore voltage I can get from this board is 1.775 after the vid 1/vid 2 pin trick. I simply can't go any higher.
Yodums, where can I get this Gigabyte 60 XET mainboard? All searches find a reference to it but nowhere you can buy one. Send me a link.
takiwa, I'll try the burn in at 124 fsb for a couple days and see what happens Although I doubt it will help.......who knows though, can't hurt to try.
Thanks all for your help and concern, I do appreciate it!

Sounds like maybe you oughta rip off the IHS. It may help. SOmetimes too much vcore is bad for these chips. I know my 1.2 @ 1.6 can't be stable at any vcore above 1.725. Some are different than others. I noticed in one of the four IHS's I ripped off I found that the inside of the IHS had a nick in it that woiuld indeed make too much of a gap. I am thinking your temps are off cause at those vcores and speeds your temps should be around 40 deg. C even at lower room temp. I use the pal 6035 on two of these chips. I know how they are supposed to act.
Skitzer it must be the mobo. First of all I would try Tawika's idea.
Try an FSB of 125 or something as the 124 doesn't have the 1/4 divider.
You should be able to find the Gigabyte 60 XET @ newegg.com

Maybe the vh6-t is different than the ST6 but the st6 can handle FSB's over 133MHz with only a 1/3 divider. Something is wrong and I doubt it is the chip! Lower vcores don't help huh? I find the most stable vcore for my cel-t at 1600MHz is 1.625v. If I set it too 1.7v it will give problems.
I am thinking your temps are off cause at those vcores and speeds your temps should be around 40 deg. C even at lower room temp.
ol' man has a point...what are you using to get your temps? I have to compensate about 4-5C on MBM5 to get a real temp...my mobo reports 35C, Sandra reports 35C, but MBM5 says 30-31C...check your temps again...my chip craps out at a little over 40...

This link (http://www.cigmall.com/gigga6sk3.html) leads you to a XET board. I shamelessly ripped the link from a thread that Big Red had posted.:D
Sorry Big Red, hope you don't mind.:p

Well, it is not the mainboard. I just went in and lowered the Vcore to 1.65 and it is actually running more stable at 133 fsb.
takiwa, you were right about the temps, in the Via hardware monitor it says 31C but Sisoft says temp is 36.8C. Big difference. It seems that temp may be the problem cause it still will not complete 3DMark 2001, gets about halfway through and then drops me back to the desktop. Which direction should I go now? Should I pop the cap? I haven't tried lapping the heatsink or IHS yet either. I think I am very close to solving this. Should I raise the Vcore a little more or drop it down a little?
Let me know what you think and as always I appreciate all the help and advice :)
****UPDATE****
Just dropped the voltage to 1.6 and it still boots right into Windows at 1463. I can even play RTCW for a while but it will not finish running 1 loop of 3DMark 2001, crashes and drops me back to the desktop or sometimes reboots. Also the temp goes up to 40C. I'm sure it's a heat problem now because the CPU runs fine 1463 at 1.6v until I put it under heavy load. Any thoughts?
If it is a heat problem, that is something you can fix eventually, with better cooling solution. But how does it do on other benches? Is 3dMark the only thing it doesn't do well on? I am inclined to believe that it may be your vid card at that FSB too. Try clocking your vid card back down to stock. Your voltages are fine...hell, mine won't boot into Windows with that low of a voltage, so the burn-in must have worked. I would concentrate on your periperals, and your BIOS settings for RAM timing...there is a magic setting in there, you just have to find it, my friend....but never give up!

Ahh you got one of the good chips that runs better at lower vcores but takes a dump at higher ones. I like my cel-t 1.2 cause it is like that:D Well that and it can do 1650+MHz on 1.65v:D Set it to 1.7v and crash city. 1.8v will not even load windows!
just tested my chip once again after reading your successes on low vcore... just power off and set the dipswitches correct ;D (wire coming out of my comp case) I tried 1.625V = no windows @1604Mhz (stops loading), back to 1.825V and everything is running fine again.

I wish mine was like that...anything under 1.705, and I can't even post...need 1.75 to load Windows, but I idle around 34C. Funny thing is, with that high vcore and idle temp, I still only see 37-39C under full load...strong damn chips :D

Maybe you've tried already, but if your using games to judge stability, try clocking your vid card lower while you're testing for cpu stability.

Well, here's the scoop. It was my video card after all. Dropped the settings down to 200/500 and ran 3DMark for several hours with no problems. Then I got brave and raised the fsb to 137, booted right into windows and ran 3DMark for about 3 loops without a problem. Downloaded CPUBurn and ran it for about an hour before it locked up. Went in and raised the Vcore to 1.65 and tried it again with success! Ran CPUBurn at highest setting for 5 hours without a problem. Looks like 1507 at 1.65v is the sweet spot for this chip. It does get warm though, 39.2C after heavy load, but I'll work on that later. My memory settings are tweaked to the max and everything seems to be running perfect.
I want to thank takiwa and ol' man for their encouragement and advice. If not for you guys I probably would have given up on this.
I'm gonna run CPUBurn at highest settings all night tonight to make sure she's totally stable. I'll make a final post here tomorrow.

Don't ever talk about the dark side again:D
Wow and to think that you didn't get far you went from 1.23 or something to 1.5 :D
Congrats and keep on going lol

If it wasn't for the guys on this forum, I would have given up on mine, too....I also had some problems. I'm happy I could help!
PS: A burn-in should help with you temps...

I knew you and the 1.1a could do it !
Crank some more fans in your case, and turn it up some more !
:D :p

hmm... my little celery 1.1a @ 1466 shows temps of 59°C (prime torture test, seems stable)... 1,675v, retail fan... the strange thing is... even at default voltage and speed the idle temp is around 43°C (my case cooling isn't THAT bad)
How dow you guys get those low temps? the retail fans aren't that bad, are they?

please say you removed the heat pad and used as2 or as3 instead.
im looking at my retail hsf right now for my 1.2 and its in SERIOUS need of lapping, hell i could cut my finger on those grooves in it.
i strongly reccomend you either lap that thing and use as2 or get a new hsf

Agreed...too bad Intel can't make a HS like they make processors...

removing the pad and applying asII was the first thing i did... i just can't believe the temps... mayby the board (asus tucl2-c) reports them wrong... the heatsink doesn't get very hot... :(
i'm considering removing the heat spreader... i cannot afford an expensive heat sink...
what are you using to monitor the temps?
ol' man
02-05-02, 03:47 PM
Get a better HS. Do not remove the IHS as your HS will not suffice and you may see higher temps actually.

Well. it has passed everything I can throw at it at 1507 at 1.65v and I can say with total certainty that it is rock stable. Took it up to 1540 and it seems to run fine there also, (didn't leave it there too long). I am going to run it at 1507 and am extremely happy with my 400mhz overclock. Bang for buck?? You bet!
Thanks again to all who gave me encouragement and help. I like this forum and think I'll stick around.
Regards, Bob.
congrats on a successful o/c, Bob, and thanks for hanging around...I may need your help someday :D And yes, bang for the buck is the understatement of the year when the tuallies are concerned...this is one mean little chip! Intel might have actually made up for the Willamette core (read: disaster) with this one...
